Ralliart, the Mitsubishi Motors Corporation’s motorsport division manufactured a World Rally Car commonly called as Mitsubishi Lancer WRC in 2001. It was designed particularly to compete in the World Rally Championship. As the previous Lancer Evolution series was designed to compete in the Group A class, there was a need to design a car to compete with the World Rally Cars manufactured by other automakers.
The engine used in the Lancer WRC was no different than the one used in sports and rally cars since 1980s, i.e. 1996 cc 4G63 engine. However, the current version can generate up to 300 PS (221 kW) at 5500 rpm and torque of 540 Nm (398 lb-ft) at 3500 rpm.
Like WRC, the WRC2 also comes with 4G63 engine with an output of 300 PS (221 kW) at 5500 rpm and torque of 540 Nm (398 lb-ft) at 3500 rpm and paired with a 60-speed INVECS-type sequential transmission through a triple-plate carbon clutch and utilize front, center and rear active differentials to distribute the power to all four wheels. The WRC2 features an independent suspension, i.e. Macpherson struts and coil springs on each corner of the vehicle. The car also features vented disc brakes mounted by 6-piston calipers at the front and 4-piston calipers at rear.
The Lancer WRC04 also came with the similar 4G63 engine mated to a 5-speed semi-automatic transmission. A new 4-wheel drive system was also introduced in the lineup and developed in collaboration with Ricardo Consulting Engineers by Mitsubishi Motors Motorsports (MMSP). The car had gone through an extensive aerodynamic testing at the Lola Cars wind tunnel. The WRC04 received upgraded front brakes, i.e. 8-piston calipers clamped with 370 mm (15 inch) discs.
The WRC04 participated in the 2004 World rally Championship under the hands of ex-Peugeot drive Gilles Panizzi along with his brother Herve who was a co-driver.
Although, there were no changes made under the hood of the new WRC05, the width of the car was increased by 30 mm (1.2 inch) in consent with the new WRC regulations. In order to improve the stability of the car, some aerodynamic changes were made in the bodywork. The suspension links and driveshafts were both extended in length. The WRC05 featured a steering-mounted gearshift paddles featuring extended rations for the first, third and fourth gears.
