The petrol engine runs through a six-speed paddle-shifted sequential transmission (again adapted from Mini), and in the sport mode it runs full-time. That's why you get such a natural impression of speed, and a real engine noise. At the moment the noise is a bit like that other turbo triple, a Smart. But they are about to add an active exhaust system to make it fruitier, as well as an electronic noise modification system through the hi-fi-speakers.
The official cycle economy figure is 104mpg. But this includes some electric range which doesn't count towards the 66g/km CO2 figure. The engineers admit that this makes it unrealistic, but they say it should do 40-50mpg even when you're pressing on.
