That heavy? This explains why Evo 1,2,3 are around 1200kg which is like 200kg heavier than Wira. The 4WD parts, heavier engine and perhaps the reinforced chassis.
Yes, I know about 4WD having much better grip on the road compared to 2WD. For a 4WD machine to launch during start, it is much easier than 2WD. For 2WD, you really need to time your RPM right before launching or else you'll risk losing grip and wheel spin. Grip and acceleration is one reason why I like 4WD cars compared to 2WD. I like cars like Evo, STI, Skyline GT-R...
Are you referring to this Optima Evo? Because I remember seeing an Optima Evo here before.
