'92 AMS Argyle 2.0T ZRD
Originally created for TMCC37 in conjunction with @Riley (who did the exterior styling) - I handled the engineering aspect.
The yellow car on the left is the original version, with a skid tray and 205-section medium compound tires, plus a softer suspension for better off-road capability. The red one on the right was made later, and is more tarmac-biased, losing the skid tray but having 225-section sports compound tires and lighter magnesium wheels in its place, while the suspension was stiffened up to exploit the extra grip they provide. Both trims are powered by a 2.0L turbo I4 driving all four wheels via a 5-speed manual gearbox and a helical LSD, with a helical center differential.
