Default The Evolution of the Evolution

Evolution I
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 2730 lb (1238 kg) GSR, while the former came with all of the conveniences of a typical street car. It came with Mitsubishi's 4G63 engine producing 247 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 Evo models. 5,000 Evo Is were sold between 1992 and 1993. It uses the frame CD9A.

Frame: CD9A

Evolution II
The successful Evo 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. Also, Mitsubishi decided to change the frame this year to CE9A, a spin off the CD9A used in the previous edition.

Frame: CE9A

Evolution III
January 1995 saw the arrival of the Evo 3- and this time the 5000 strong production run was brought up more quickly than the Evo 2. The Evo 3 looked more serious, with its new nose moulding (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 aluminium bonnet a new TDO5-16G6-7 Turbo, new exhaust system and increased compression brought another 10ps power rise, Torque output was unaltered, apart from a higher final drive ratio. Both GSR and RS still used the same 5speed gearbox. Interior tweaks were limited to a new Momo steering wheel (GSR only) and new fabric on the Evo 2 type Recaros. The specs on this vehicle were an engine size of 1997 cc, 270 [email protected] rpm, Torque was 228 lb ft at 3000 rpm. weight is 1260 kg (rs 1190 kg) A top speed of 149 mph and 0-60 in 4.9secs. This model still uses the same frame. (CE9A)

Frame: CE9A

Evolution IV
The Lancer platform was completely changed in 1996, and along with it the Evo, 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 2 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" 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-just heater, 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 6500 rpm and 260 ft·lbf (352 Nm) of torque at 3000 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 Evo IVs produced all sold quickly. The Evo IV can be distinguished by its two large foglights on the front bumper, and the newly designed tail lights on the rear, which became a standard design to Evo 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 and the GSR being 1345 kg. This was the only model year to use the CN9A as its frame.

Frame: CN9A.

Evolution V
In 1997, the WRC created a new class, "World Rally Car", and while these cars still had to abide by Group A standards, they did not have to meet homologation rules. Mitsubishi redesigned the Evo IV with this in mind and introduced the Evo 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 relaced the IV FRP version and gave an adjustable angle of attack to alter rear down force. The track was widened by 10 mm, 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 mm. 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.

Further more, 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.

Frame: CP9A

Evolution VI

Evo Evo 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 Evo VI received new bodywork yet again, with the most easily spotted change in the front bumper where the huge foglights 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, and was tuned by Ralliart to be lighter and more powerful with 330 hp.

Yet another special edition Evo 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 Red/Black Recaro seats (with emmbosed T. Makinen logo), 17" ENKEI white wheels, a leather MOMO steering wheel and shift ****, a titanium turbine that spooled up quicker, front upper strut brace, lowered with tarmac stages in mind, a quicker lock to lock and amongst others colours, 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 Evo 6¹/² .

It was during the Evo VI's model run that American car enthusiasts, who had been previously denied the Evolution models, began to clamour for its introduction to the United States. This was primarily due to exposure of the Evolution in video games such as the Gran Turismo series.

This was the last Lancer Evo Homologation Special

Frame: CP9A on both the TME and standard edtions.
