The CityCruiser W4 is not so perfect for spirited driving. You asked for it, a CityCruiser W4 which is good enough for spirited driving; the W4S. The W4S is based on the normal W4 but with lowered ride height and somewhat stiffer springs so it's not as bouncy as the W4.
Specs? It has the same 160hp 190Nm Inline 3 Turbo 1.5 litre 'Z' engine. It powers all the four wheels via a 7-speed dual-clutch transmission. To enhance handling, the CityCruiser W4S has electric clutch-type limited-slip differential at the front and back. The power split is helped by Quadvector, to achieve the most optimal power distribution.
The W4S is sitting on the same set of 16-inch magnesium alloy wheels. This time, the W4S received a bit wider tires; 215/45/R16 with V speed rating.
