THERE are many stand-out features in the Evo, not least the adjustable double-deck rear wing, the weight-saving aluminium bonnet, the superb Recaro seats and Momo steering wheel, the 103kW/litre engine and throttle body water-spray. But the most interesting and effective is the Active Yaw Control diff. Using a number of engine, steering and wheel sensors to detect when the car yaws, or gets sideways, the system works ingeniously well without dulling the driving experience.
