Evolution
I, inherited the 2-liter 4G63-type in-line 4-cylinderDOHC intercooler-turbocharged
plant. For Evolution I, the engine was given a largercapacity intercooler,
a higher compression ratio, modified port configuration, new injectors,
and lighter crankshaft, con rods and pistons. These changes resulted
in a 10PS increase in maximum power to 250PS at 6000 rpm, and maximum
torque of 31.5Kg-m at 3000rpm.
Evolution I also inherited the VR-4 driveline. Modifications included the use of double-cone synchromesh on second gear for improved shift action and durability, an uprated clutch with more positive pedal action. To match the heavier front end and the substantial increase in suspention inputs, the body underwent a major strengthening and stiffness optimization program resulting in a 20% increase in torsional stiffness over the base model. To alleviate the weight increase stemming from the extra reinforcement, the vibration-damping undercoat was totally eliminated. Evolution's suspension used MacPherson strut and a multi-link arrangement to locate and control the front and rear wheels respectively. Optimized to increase stiffness, pillow ball upper mounts were used to replace rubber bushings on the rear upper and lower control arms and the outer control links. Evolution's exterior was distinguished at the front by an aluminum engine hood with large air outlets, and open grille-integral front bumper extended 40mm forwards to house the uprated intercooler unit. At the rear, a large reardeck spoiler reduced lift by 18%. At 1,170kg (RS), Evolution I weighed substantially less than the 1,350kg of Galant VR-4 and with the extra 10PS squeezed out of its engine, this well-finished sports sedan delivered superb performance on the road. |
