In 1997, the WRC developed a new "World Rally Car" class, and while these cars still had to comply with the rules of group A do not have to meet standards for approval. Mitsubishi redesigned the Evolution IV with this in mind, and presented the evolution of V in January 1998.
Many aspects of the car were changed such as:
* The interior has been enhanced in the GSR version with a better class of Recaro seat.
* The body kit had burned arches in the front and rear and a new aluminum rear spoiler
replaced the IV FRP version and gave an adjustable angle of attack to change the force back.
* The track has been widened by 10 mm (0.4 in), the wheel offset changed from ET45 to ET38
along with the diameter of the wheels from 16 "to 17" to accommodate Brembo brakes which
were added to improve braking.
* In addition, the brake master cylinder bore increased by 0.3 millimeters (0.01 in).
* The engine has been strengthened in some areas and the duration of the campaign increased.
evo V and evo X
The pistons are lighter with a smaller skirt area. 510 cc injectors were replaced with 560 cc injectors for better reliability due to the electric motor more "free" and the ecu was changed to include a flash ROM.
Furthermore, the turbocharger was again improved. The torque was increased to 275 ft lbf (373 N m) at 3000 rpm. Officially, the power stayed the same, 280 hp (276 kW hp/206) as agreed by Japan in the automotive gentlemen's agreement that all cars would have 276 hp or less, but some say horsepower was actually somewhat higher.
