MIVEC

2008-08-13T17:27:00.018+07:00

MIVEC (Mitsubishi Innovative Valve timing Electronic Control system) is the brand name of a variable valve timing engine technology developed by Mitsubishi Motors. MIVEC, as with other similar systems, varies the timing, lift and duration of the valves by using two different camshaft profiles. At low speeds, a mild (low-lift) cam lobe provides stable idle, lower emissions and increased torque at lower speeds, while above a fixed engine speed a second set of cam lobes are activated, providing higher lift and duration; therefore a greater quantity of air into the combustion chamber which increases the power and torque output over a broad engine speed range.
From 4B1 engine family onward, MIVEC has fully evolved into a continuous variable valve timing system (dual VVT on intake and exhaust valves). MIVEC incorporated in 3B2, 3A9 and 4A9 engine family continuously varies only the intake valves. Many older implementations only vary the valve timing (the amount of time per engine revolution that the intake port is open) and not the lift.
MIVEC was first introduced in 1992 in their 4G92 powerplant, a 1,597 cc naturally aspirated DOHC 16 valve straight-4. At the time, the first generation of the system was named Mitsubishi Innovative Valve timing and lift Electronic Control. The first cars to use this were the Mitsubishi Mirage hatchback and the Mitsubishi Lancer sedan. While the conventional 4G92 engine provided 145 PS at 7000 rpm, the MIVEC-equipped engine could achieve 175 PS at 7500 rpm. Similar improvements were seen when the technology was applied to the 1994 Mitsubishi FTO, whose top-spec GPX variant had a 6A12 1997 cc DOHC 24 valve V6 with peak power of 200 PS at 7500 rpm. The GR model, whose otherwise identical powerplant was not MIVEC-equipped, produced 170 PS at 7000 rpm by comparison.
Although initially designed to enhance performance, the system has subsequently been developed to improve economy and emissions, and has been introduced across Mitsubishi's range of vehicles, from the i kei car to the high-performance Lancer Evolution sedan.

Operation
Some types of variable valve control systems optimize power and torque by varying valve opening times and/or duration. Some of these valve control systems optimize performance at low and mid-range engine speeds. Others focus on enhancing only high-rpm power. MIVEC system provides both of these benefits by controlling valve timing and lift. The basic operation of the MIVEC system is altering the cam profiles and thus tailoring engine performance in response to driver input.
In essence, MIVEC serves the same function as "swapping cams", something that car racers might do when modifying older-design engines to produce more power. However, such swaps come with a compromise - generally yielding either greater low-end torque or more high-end horsepower, but not both. MIVEC achieves both goals. With MIVEC, the "cam swap" occurs automatically at a fixed engine speed. The cam switch operation is transparent to the driver, who is simply rewarded with a smooth flow of power.
Two distinct cam profiles are used to provide two engine modes: a low-speed mode, consisting of low-lift cam profiles; and a high-speed mode. The low-lift cams and rocker arms - which drive separate intake valves - are positioned on either side of a centrally located high-lift cam. Each of the intake valves is operated by a low-lift cam and rocker arm, while placing a T-lever between them allows the valves to follow the action of the high-lift cam.
At low speeds, The T-lever's wing section floats freely, enabling the low-lift cams to operate the valves. The intake rocker arms contain internal pistons, which are retained by springs in a lowered position while the engine speed is below the MIVEC switchover point, to avoid contacting the high-lift T-shaped levers. At high speeds, hydraulic pressure elevates the hydraulic pistons, causing the T-lever to push against the rocker arm, which in turn makes the high-lift cam operate the valves.
In summary, MIVEC switches to the higher cam profile as engine speed increases, and drops back to the lower cam profile as engine speed decreases. The reduced valve overlap in low-speed mode provides stable idling, while accelerated timing of the intake valve's closing reduces backflow to improve volumetric efficiency, which helps increase engine output as well as reduce lift friction. High-speed mode takes advantage of the pulsating intake effect created by the mode's high lift and retarded timing of intake valve closure. The resulting reduced pumping loss of the larger valve overlap yields higher power output and a reduction in friction. The low- and high-speed modes overlap for a brief period, boosting torque.
In the systems latest generation (4B1 engine family), intake and exhaust cam timing is continuously independently controlled to provide four optimized engine-operating modes:

Under most conditions, to ensure highest fuel efficiency, valve overlap is increased to reduce pumping losses. The exhaust valve opening timing is retarded for higher expansion ratio, enhancing fuel economy.

When maximum power is demanded (high engine speed and load), intake valve closing timing is retarded to synchronize the intake air pulsations for larger air volume.

Under low-speed, high load, MIVEC ensures optimal torque delivery with the intake valve closing timing advanced to ensure sufficient air volume.

At the same time, the exhaust valve opening timing is retarded to provide a higher expansion ratio and improved efficiency.At idle, valve overlap is eliminated to stabilize combustion.

MIVEC-MD
In the early years of developing its MIVEC technology, Mitsubishi also introduced a variant dubbed MIVEC-MD (Modulated Displacement), a form of variable displacement. Under a light throttle load, the intake and exhaust valves in two of the cylinders would remain closed, and the reduced pumping losses gave a claimed 10–20 percent improvement in fuel economy. Modulated Displacement was dropped around 1996.

Overhead camshaft

2008-08-07T11:49:00.004+07:00

Overhead camshaft, commonly abbreviated to OHC, valvetrain configurations place the engine camshaft within the cylinder heads, above the combustion chambers, and drive the valves or lifters in a more direct manner compared to Overhead valves (OHV) and pushrods.Compared to OHV pushrod (or I-Head) systems with the same number of valves the reciprocating components of the OHC system are fewer and have a lower total mass. Though the system that drives the cams may become more complex, most engine manufacturers easily accept the added complexity in trade for better engine performance and greater design flexibility. Another performance advantage is gained as a result of the better optimized port configurations made possible with overhead camshaft designs. With no intrusive pushrods the overhead camshaft cylinder head design can use straighter ports of more advantageous crossection and length.
The OHC system can be driven using the same methods as an OHV system, which include using a rubber/kevlar toothed timing belt, chain, or in less common cases, gears.
Many OHC engines today employ Variable Valve Timing and multiple valves to improve efficiency and power. OHC also inherently allows for greater engine speeds over comparable cam-in-block designs.
There are two overhead camshaft layouts:

Single overhead camshaft - or SOHC
Double overhead camshaft - or DOHC

Single overhead camshaft

Single overhead camshaft A single overhead camshaft cylinder head from a 1987 Honda CRX Si.
Single overhead camshaft (SOHC) is a design in which one camshaft is placed within the cylinder head. In an inline engine this means there is one camshaft in the head, while in a V engine or a horizontally-opposed engine (boxer; Flat engine) there are two camshafts: one per cylinder bank.
The SOHC design has less reciprocating mass than a comparable pushrod design. This can allow for higher engine speeds, which in turn will increase power output for a given torque. The cam operates the valves directly or through a rocker arm, as opposed to overhead valve pushrod engines which have tappets, long pushrods, and rocker arms to transfer the movement of the lobes on the camshaft in the engine block to the valves in the cylinder head.
SOHC designs offer reduced complexity compared to pushrod designs when used for multi-valve heads in which each cylinder has more than two valves. An example of a SOHC design using shim and bucket valve adjustment was the engine installed in the Hillman Imp (4 cylinder, 8 valve), a small early 1960s 2-door saloon car with a rear mounted alloy engine based on the Coventry Climax FWMA race engines. Exhaust and inlet manifolds were both on the same side of the engine block (thus not a crossflow cylinder head design). This did, however, offer excellent access to the spark plugs.
In the early 1980s Toyota and Volkswagen also used a directly actuated, SOHC parallel valve configuration with two valves for each cylinder. The Toyota system used hydraulic tappets while the Volkswagen system used bucket tappets with shims for valve lash adjustment. Of all valvetrain systems this is the least complex configuration possible.

Double overhead camshaft

A double overhead camshaft (also called DOHC, dual overhead cam, or twin cam (TC)) valve train layout is characterized by two camshafts being located within the cylinder head, one for inlet and one for exhaust valves. Typical automotive engines equipped with dual overhead camshafts can have from two to four camshafts in total, depending on the engine configuration. The term Twin Cam doesn't tell the exact location of camshafts, but it is mostly used to describe DOHC structure.
Double overhead camshafts are not required in order to have multiple inlet or exhaust valves, but are necessary for more than two valves that are directly actuated (though still usually via tappets). Not all DOHC engines are multivalve engines — DOHC was common in two valve per cylinder heads for decades before multivalve heads appeared. Today, however, DOHC is synonymous with multi-valve heads since almost all DOHC engines have between three and five valves per cylinder.

Mitsubishi Sirius engine

2008-08-07T11:38:00.001+07:00

The Mitsubishi Sirius or 4G6 engine is the name of one of Mitsubishi Motors' four series of straight-4 automobile engines, along with Astron, Orion, and Saturn.

The 4G61

The 4G61 displaces 1595 cc (82.3 x 75.0 mm bore/stroke). This engine was always DOHC 16-valve and used either Multi-point (MPFI) or Electronic Control (ECFI) fuel injection. A turbocharged version was also produced for the Mirage and Lancer. The 4G61 does not have balance shafts like the other 4G6x motors. Instead, it has different components, some of which can be used on the "Silent Shaft" engine.
Performance:

4G61 91kW-124HP/6500 142Nm/5000
4G61T (USA/Canada only) 99kW-135HP/6000 191Nm/3000
4G61T (Japan) 160HP-117.68kW/6000 220.65Nm/2500

Applications:

1988–1992 Mitsubishi Mirage / Mitsubishi Colt (MPFI)
1988–1992 Dodge Colt / Plymouth Colt
1988–1992 Eagle Summit1992–1995 Hyundai Elantra

4G62

The larger 1.8 L 4G62 was an SOHC 8-valve unit for longitudinal rear-wheel drive and all-wheel drive use. With an 80.6 x 88.0 mm bore / stroke, it displaced 1795 cc.

Applications:

1983–1989 Mitsubishi Cordia
1988 Mitsubishi Tredia

4G63

The 4G63 was a 1997 cc version. (85mm Bore x 88 mm Stroke) SOHC and DOHC were produced. The DOHC version was introduced in 1987 in the Japanese market Galant VR-4 and came turbocharged or naturally aspirated. It is found in various models including the 1988-92 Galant VR-4 and the U.S. market 1990-1999 Eclipse.
The SOHC version was used in Mitsubishi Galant models until 1993. It has 76 kW of output and 157 NM of torque at 4750 rpm.
The Mitsubishi Eclipse, Eagle Talon and Plymouth Laser introduced the DOHC turbocharged intercooled version to the U.S. in 1989 through Diamond Star Motors, a joint venture between Mitsubishi Motors and the Chrysler Corporation. 1990 to late April 1992 came with beefier rods and used 6 bolts to secure the flywheel to the crankshaft, May 1992 to present EVO versions have lighter rods and use 7 bolts to secure the flywheel to the crankshaft. They are referred to as the "six bolt" and "seven bolt" engines, respectively.
Output for the 2003 Japanese/US Mitsubishi Lancer Evolution is 271 hp (202 kW) at 6500 rpm with 273 ft·lbf (370 N·m) of torque at 3500 rpm. It has a cast iron engine block and aluminum DOHC cylinder head. It uses multi-point fuel injection, has 4 valves per cylinder, is turbocharged and intercooled and features forged steel connecting rods. With the release of the Lancer Evolution IX ( 286 hp @ 6500rpm, 289ft*lb of @ 3500rpm, 7000 rpm redline), it has received Mitsubishi's MIVEC variable valve timing system, which gives smoother power delivery and a flatter torque curve.
In the United Kingdom, a special Lancer Evolution, the FQ-400, produces 302.13 kW (405.2 hp), from a 4G63 engine. At 202.6 hp (151.3 kW) per liter, it has possibly the highest specific output per liter of any production engine.

Racing
Its turbocharged variant, 4G63T (also sometimes referred to simply as the 4G63), has powered Mitsubishi vehicles in World Rally Championships for years in the Mitsubishi Galant VR-4, Lancer Evolution, Carisma GT and Lancer WRC04. It was the powerplant of the Lancer Evolution when Tommi Mäkinen won his four sequential WRC championships.

Misubishi Evo X

2008-07-14T18:31:00.044+07:00

In 2005, Mitsubishi introduced a concept version of the next-gen Evolution at the 39th Tokyo Motor Show named the Concept-X.Mitsubishi unveiled a second concept car, the Prototype-X, at the 2007 North American International Auto Show (NAIAS).The Lancer Evolution X sedan features a newly designed 4B11T 2.0 L turbocharged, all-aluminum inline-4 engine. Power and torque depend on the market but all versions will have at least 280 PS (205.9 kW/276.2 hp) (JDM version), the American market version will have slightly more. The UK models will be reworked by Mitsubishi UK, in accordance with previous MR Evolutions bearing the FQ badge. Options for the UK Evolutions are expected to be between 300 hp (220 kW) and 360 hp (270 kW). Two versions of the car will be offered in the U.S. The Lancer Evolution MR, with 6-speed Twin Clutch Sportronic Shift Transmission (TC-SST). The other version is the GSR which will have a 5-speed manual transmission system. The car has also a new full-time four-wheel drive system named S-AWC (Super All Wheel Control), an advanced version of Mitsubishi's AWC system used in previous generations. The S-AWC uses torque vectoring technology to send different amount of torque to any wheel at any given time.
It also features Mitsubishi's new sequential semi-automatic six speed Twin Clutch SST twinclutch transmission with steering-mounted magnesium alloy shift paddles. A 5-speed manual gearbox will also be available. Mitsubishi claims that the 5 speed manual transmission has always been preferred in rallying and should be very refined, resulting in a more satisfying drive. New Lancer Evolution will incorporate Mitsubishi's next generation RISE safety body.
The production version of Prototype-X has begun production in Autumn 2007. The Evolution X went on sale October 1, 2007 in Japan then in January 2008 in the U.S.A., February in Canada (as the first version of Evolution in Canada) and in March 2008 in the UK at prices between £27,499 and £37,999.

Misubishi Evo IX

2008-07-14T17:21:00.012+07:00

Mitsubishi introduced the Lancer Evolution IX in Japan on March 3, 2005, and exhibited the car at the Geneva Motor Show for the European market the same day.The North American markets saw the model exhibited at the New York International Auto Show the following month.The 2.0 L 4G63 engine got MIVEC technology (variable valve timing), boosting official power output at the crankshaft to 286 hp (213 kW) and torque to 289 ft·lbf (392 N·m). The Evolution VIII first offered in 2003 would produce dynamometer readings of approximately 225 WHP and 225 lb·ft (305 N·m). WTQ with a flywheel power rating of 271/273 respectively. The Evolution IX typically pulls 255 WHP and 250 WTQ on a wheel dynamometer, a difference of 30 hp (22 kW).
The USDM Lancer Evolution IX models (standard; "GSR" in some markets), RS, SE, and MR) varied slightly in their performance capabilities. Subtleties unique to each model accounted for variations in acceleration, handling and top speed. The RS excluded features standard on the standard, SE and MR models (stereo system, power windows and locks, rear wiper, rear wing, trunk lining and sound insulation). The resulting weight savings of over 60 lb (27 kg) gave the RS a subtly sharper handling responsiveness that helped it shave fractions of a second off the lap times of other models on an identical course.[citation needed] However, the top-end MR had a high top speed, since its 6th forward gear allowed it to reach 165 mph (266 km/h) at 7,000 rpm compared to 157 mph (253 km/h) at 7,000 rpm in 5th for the RS and middle-positioned IX models.[citation needed] (Note: Data relevant to U.S. model specifications)
The IX MR retained the features of the Evolution VIII MR, like Bilstein shocks, a 6-speed manual transmission, a rooftop vortex generator, BBS forged wheels, HID xenon headlights, foglights, accessory gauge package, "zero lift" kit, special badging and an aluminum roof. All models continued to sport Recaro bucket seats, Brembo brakes and MOMO steering wheels. Additional revisions from 2005 included a closer gear ratio for the 5-speed manual transmission, new lighter Enkei wheels on non-MR models, a redesigned front end with a more efficient air dam (the most noticeable feature are the two small oval ducts to cool the intercooler pipes), and a new rear bumper with a diffuser undersurface to smooth out the airflow coming out of the car for non-US models. In an effort to reduce the price increase on the Evolution IX model,[citation needed] HID headlights were no longer standard equipment on the base IX (nor were they standard on the 2005 VIII), and were available only in the SSL package (Sun, Sound, and Leather), SE (Special Edition) and MR trims.
Three trims were available for Japan, Asia and Europe. Although all models used the same 286 hp (213 kW) engine, the torque differed from one model to another. In Europe, however, the Evolution IX was advertised to have 280 hp (206 kW). The GSR produced 295 ft·lbf (400 N·m) of torque, while the RS and GT produced 300 ft·lbf (407 N·m).

- RS - "ralli sport", revised 5-speed, aluminium roof, gauge pack, minimal interior, LSD and a titanium-magnesium turbine, left-hand drive option available.
- GT - revised 5-speed, this is basically the RS mechanically, but with some of the GSR's features (mainly interior pieces).
- GSR - 6-speed, Bilstein monotube shocks, aluminium roof, gauge pack, SAYC (Super Active Yaw Control), and double-din radio (this is roughly equivalent to the USDM MR).
In the United Kingdom, the Evolution IX used a different model scheme based on the car's horsepower. There were initially three models available: the FQ-300, FQ-320 and FQ-340 each with around 300, 320 and 340 bhp (254 kW) respectively. An FQ-360 model was subsequently released as a successor to the Evolution VIII FQ-400. While the new FQ-360 produced less horsepower than its predecessor, it had more torque at 363 lb·ft (492 N·m) at 3200 rpm - 8 lb·ft (11 N·m) more than the FQ-400. All four models were designed to run on super unleaded petrol only.
- FQ-300, 320, 340 - 6-speed, Bilstein monotube shocks, AYC (Active Yaw Control), super unleaded petrol only
- FQ-360 - 6-speed, Bilstein monotube shocks, AYC (Active Yaw Control), Ralliart Sports Meter Kit, carbon front splitter, Speedline alloy wheels, super unleaded petrol only
All four models were available in the US. All models used the same 286 hp (213 kW) engine. All models used a front and rear Limited Slip Differential, and an Active Center Differential.
- Standard - revised 5-speed, standard model
- RS - ralli sport, revised 5-speed, aluminum roof, gauge pack, minimal interior
- SE - Special Edition, aluminum roof/hood, and front fenders, split seven-spoke forged aluminum BBS wheels in "diamond black" finish, HID headlights with integrated fog lights, red-stitched Recaro seats
- MR - 6-speed, Bilstein monotube shocks, split seven-spoke forged aluminum BBS wheels, aluminum roof, hood, and front fenders, gauge pack, HID headlights with integrated fog lights, vortex generator, and custom MR badging.

All of the American models are the same in power and performance. The only thing that sets them apart is the Evo RS, which is 80 lbs lighter than the MR and SE models.
To the standard (or "GSR") model, the Sun, Sound and Leather package added a power sunroof, HID xenon headlamps with integrated fog lights, a slightly different stereo headunit (with no integral amplifier), slightly upgraded speakers in the front doors and parcel shelf, a 4.1-channel amplifier under the driver's seat, a powered, trunk-mounted Infinity subwoofer, black leather seating surfaces, leather-trimmed door panels, slightly revised center armrests in the front and rear, and separate rear side headrests. This model deleted the GSR's headliner-mounted sunglass holder to make room for the sunroof.
A 2,500-piece, limited edition Evolution IX station wagon was released in Japan soon after the sedan's debut. It used the back end of the Lancer Sportback wagon grafted onto the sedan. Two trim models were introduced: the GT with a six-speed manual transmission and the GT-A with a 5-speed automatic. Other than the station wagon rear end, redesigned seats and some chromed trims, the car's interior was the same as the sedan.
Mitsubishi also developed the Evolution MIEV, based on the Evolutions IX's chassis but with four electric motors connected to the wheels as a test bed for the Mitsubishi In-wheel Electric Vehicle (MIEV) next-generation electric vehicle. The in-wheel motors used a hollow doughnut construction to locate the rotor outside the stator, unlike other electric motors where the rotor turns inside the stator. The result of this was a lighter motor which translated into lower unsprung weight than a system with the motors mounted in the wheels. Each in-wheel motor produced a power output of 68 hp (51 kW), thus giving a combined output of 272 hp (203 kW), comparable to that of regular, petrol powered Lancer Evolutions. The car competed in the Shikoku EV (Electric Vehicle) Rally 2005.

Misubishi Evo VIII

2008-07-14T17:21:00.001+07:00

The Evolution was changed again in 2003, this time sporting Super Active Yaw Control to handle traction and a 6-speed manual gearbox. It was available with 280 PS (276 hp/206 kW) in three trims: standard (GSR in Japan), RS (devoid of all excess components, such as interior map lights, power windows/doors, and radio) and MR. RS Editions came with a revised limited-slip front differential. The new Evolution also sported Altezza taillights.
The Lancer Evolution VIII is unique among its successors and predecessors, since it is so far the only Evo that used the same central semi-triangle core that was used by Lancer, Adventure, Strada, Grandis, and Outlander.
The Lancer Evolution VIII MR uses slick-response Bilstein shocks for improved handling. The aluminium roof panel and other reductions in body weight have lowered the centre of gravity to realize more natural roll characteristics. Detail improvements have also been made to Mitsubishi’s own electronic all-wheel drive, to the ACD 5 + Super AYC 6 traction control and to the Sports ABS systems. The Lancer Evolution VIII displayed at the 2003 Tokyo Motor Show took the MR designation traditionally reserved for Mitsubishi Motors high-performance models and used first on the Galant GTO. Other parts on the MR include BBS alloy wheels, Bilstein shocks, and an aluminium roof. In the United Kingdom, many special Evolutions were introduced, which included FQ300, FQ320, FQ340, and FQ400 variants. They each came with 305, 320, 340, and 400 hp (227, 239, 254 and 298 kW), respectively. It is rumored that the 'FQ' stands for 'Fucking Quick'.The FQ400, sold through Ralliart UK, produces 302.13 kW (405.2 hp), from its 2.0 L 4G63 engine as the result of being specially modified by United Kingdom tuning firms Rampage Tuning, Owen Developments, and Flow Race Engines. At 202.9 hp (151.3 kW) per litre, it has one of the highest specific output per litre of any roadcar engine. With a curb weight of around 3200 lb (1450 kg), it achieves 0-60 mph in 3.5 seconds and 0-100 mph in around 9 seconds, top speed is 174 mph (280km/h), whilst costing about £47,000. BBC's television series Top Gear demonstrated that the FQ-400 could surprisingly keep up with a Lamborghini Murcielago around a test track. The Stig recorded a Top Gear Power Lap Times of 1 minute 24.8 seconds, 4.2 seconds quicker than the Murcielago's time of 1 minute 29 seconds.In a similar test conducted by UK supercar magazine evo, the Evolution was able to lap the Bedford Autodrome faster than an Audi RS4 and a Porsche Carrera 4S.

Misubishi Evo VII

2008-07-14T17:20:00.046+07:00

In 2001, Mitsubishi was forced by the FIA to race in the WRC using WRC rules for building a car instead of the Group A class rules, and thus did not need to follow homologation rules. The Evolution VII was based on the larger Lancer Cedia platform and as a result gained more weight over the Evolution VI, but Mitsubishi made up for this with multiple important chassis tweaks. The biggest change was the addition of an active center differential and a more effective limited-slip differential, while a front helical limited-slip differential was added. Torque was increased again to 284 ft·lbf (385 N·m) with engine tweaks that allowed greater airflow, and horsepower officially remained at 280 PS (276 hp/206 kW). Despite its pedestrian appearance, the Evolution VII can outrun many more expensive cars (such as the Ferrari 360 Modena, as seen in Best Motoring videos.)
The introduction of the Evolution VII also marked the first time an automatic drivetrain was included within the model lineup—the GT-A. Seen as the 'gentleman's express' version of the visually similar VII GSR, the GT-A model was only produced in 2002 and had the following distinguishing interior and exterior specification: GT-A-only diamond cut finish 17-inch (430 mm) alloy wheels, clear rear light lenses and all-in-one style front headlights (later used on the Evolution VIII). The GT-A had the option of either no spoiler, the short spoiler (as later used on the Evolution VIII 260) or the thunderspoiler as used on the standard Evolution VII models. The most distinguishing feature was a smooth bonnet with no air-grills on it at all. Although offering inferior cooling capabilities, the bonnet was designed to give a cleaner line through the air with less air resistance at motorway speeds.
Interior could be specified with factory options of a deluxe velour interior, full leather or the Recaro sports seats. The GT-A interior was different in that it had chromed door handles, a different instrument panel (to show the gear selection) and chrome edged bezels around the speedo and tach. The GT-A also had additional sound deadening installed from the factory and the engine manifold and downpipe had been engineered to be quieter.
The 5-speed automatic gearbox had what Mitsubishi called "fuzzy logic", which meant that the car would learn what the driver's driving characteristics were like and would adapt the gear change timings and kick down reactions accordingly. The gears could be manually selected as with most tiptronics via steering wheel + and - buttons (a pair both sides) or via selecting the tiptronic gate with the gear lever. Power was down a little from the standard manual cars with a very usable 272 bhp (203 kW). The GT-A gearbox did not appear again in the Evolution VIII but has been installed in the estate version of the Evolution IX Wagon.

Misubishi Evo VI

2008-07-14T17:20:00.044+07:00

The Evolution VI's changes mainly focused on cooling and engine durability. It received a larger intercooler, larger oil cooler, and new pistons, along with a titanium-aluminide turbine wheel for the RS model, which was a first in a production car. Also, the Evolution VI received new bodywork yet again, with the most easily spotted change in the front bumper where the huge fog lights were reduced in size and moved to the corners for better airflow. A new model was added to the GSR and RS lineup; known as the RS2, it was an RS with a few of the GSR's options. Another limited-edition RS was known as the RS Sprint, an RS tuned by Ralliart in the UK to be lighter and more powerful with 330 hp (246 kW).
Yet another special edition Evolution VI was also released in 1999: the Tommi Makinen Edition, named after Finnish rally driver Tommi Makinen that had won Mitsubishi four WRC drivers championships. It featured a different front bumper, Red/Black Recaro seats (with embossed T. Makinen logo), 17" ENKEI white wheels, a leather MOMO steering wheel and shift knob, a titanium turbine that spooled up quicker, front upper strut brace, lowered ride height (with tarmac stages in mind), and a quicker steering ratio. Amongst other colours, the Evo VI came in an exclusive shade of red with special decals, replicating Tommi Makinen's rally car's colour scheme. This car is also sometimes referred to as an Evolution 6½, Evolution 6.5, or TME for short.

Misubishi Evo V

2008-07-14T17:19:00.013+07:00

In 1997, the WRC created a new "World Rally Car" class, and while these cars still had to abide by Group A standards, they did not have to meet homologation rules. Mitsubishi redesigned the Evolution IV with this in mind and introduced the Evolution V in January of 1998.
Many aspects of the car were changed such as:
- The interior was upgraded in the GSR version with a better class of Recaro seat.
- The body kit had flared arches at the front and rear and a new aluminium rear spoiler replaced the IV FRP version and gave an adjustable angle of attack to alter rear down force.
- The track was widened by 10 mm (0.4 in), the wheel offset changed from ET45 to ET38 along with the wheel diameter which rose from 16" to 17" to accommodate Brembo brakes which were added to enhance braking.
In addition the brake master cylinder bore increased by 0.3 millimetres (0.01 in).
- The engine was strengthened in a few areas and the cam duration was increased. The pistons were lighter with a smaller skirt area. 510 cc injectors were replaced with 560 cc injectors for better engine reliability due to more electrical "headroom" and the ecu was changed to include a flash ROM.
Furthermore, the turbocharger was again improved. Torque was increased to 275 ft·lbf (373 N·m) at 3000 rpm. Power officially stayed the same, at 280 PS (276 hp/206 kW) as agreed by Japan's automotive gentlemen's agreement that all cars would have 276 or less hp, but some claim horsepower was actually somewhat higher.

Misubishi Evo IV

2008-07-14T17:19:00.008+07:00

The Lancer platform was completely changed in 1996, and along with it the Evolution, which had become extremely popular throughout the world. The engine and transaxle was rotated 180° to better balance the weight and eliminate torque steer. There were two versions available, The RS and GSR. The RS version was produced as a competition car with a limited-slip front differential and a friction type LSD at the rear. It also came with GLX seats and 16" (41 cm) steel wheels as these were items that would be replaced by anyone entering the car into competition events. The RS also had wind up windows, no air conditioning, and a few extra brace bars to strengthen the chassis, one behind the front grill and the other across the boot floor. The RS also had a factory option of thinner body panels and thinner glass. The GSR and the RS shared a new twin scroll turbocharger which helped to increase power to 280 PS (276 hp/206 kW) at 6,500 rpm and 260 ft·lbf (352 N·m) of torque at 3,000 rpm. Mitsubishi's new Active yaw control appeared as a factory option on the GSR model, which used steering, throttle input sensors and g sensors to computer-hydraulically controlled torque split individually to the rear wheels and as a result the 10,000 Evolution IVs produced all sold quickly. The Evolution IV can be distinguished by its two large fog lights in the front bumper (option on RS version), and the newly designed tail lights on the rear, which became a standard design to Evolution VI, which would become yet another trademark of the Evolution series. This new generation was slightly heavier than previous Evos—the GSR in particular due to the added technology systems—but to counter this the car produced even more power—the weight of the RS being 1260 kg (2778 lb) and the GSR being 1345 kg (2965 lb).

Misubishi Evo III

2008-07-14T17:18:00.001+07:00

January 1995 saw the arrival of the Evolution 3- and this time the 5,000 strong production run was bought up more quickly than the Evolution 2. The Evolution 3 looked more serious, with its new nose molding (to channel air better to the radiator, intercooler, and brakes). New side skirts and rear corners, while the rear wing had grown again to reduce lift. Under the vented aluminum bonnet a new TDO5-16G6-7 Turbo, new exhaust system and increased compression brought another 10 PS (10 hp/7 kW) power rise, Torque output was unaltered, apart from a higher final drive ratio. Both GSR and RS still used the same 5 speed quaife gearbox. Interior tweaks were limited to a new Momo steering wheel (GSR only) and new fabric on the Evolution 2 type Recaros. The specs on this vehicle were an engine 4G63T size of 1997 cc, 270 bhp (201 kW) at 6250 rpm, torque was 228 lb·ft (309 N·m) at 3000 rpm, weight is 1260 kg (RS 1190 kg). A top speed of 149 mph (240 km/h) and 0-60 mi/h in 4.9 s.

Misubishi Evo II

2008-07-14T17:16:00.001+07:00

The successful Evolution I was changed in December of 1993, and was produced until 1995. It consisted mainly of handling improvements, including minor wheelbase adjustments, larger swaybars, bodywork tweaks including a larger spoiler, and beefier tires. Power output was increased to 256 PS (252 hp/188 kW) from the same engine and torque was unchanged for both GSR and RS models.

Misubishi Evo I

2008-07-14T17:10:00.001+07:00

The Evolution I was introduced in 1992 to compete in the World Rally Championship.
It used the 2.0 L turbocharged DOHC engine and 4WD drivetrain from the original Galant VR-4 in a Lancer chassis, and was sold in GSR and RS models. The latter was a stripped-down club racing version that lacked power windows and seats, anti-lock brakes, a rear wiper, and had steel wheels to save approximately 155 lb (70 kg) less than the 2,730 lb (1,238 kg) GSR, while the former came with all of the conveniences of a typical street car. It came with Mitsubishi's 4G63 engine producing 250 PS (244 hp/182 kW) at 6000 rpm and 228 ft·lbf (309 N·m) at 3000 rpm, along with all wheel drive which would become a trademark on all Evolution models. 5,000 of the first generation Evolutions were sold between 1992 and 1993.
