Hybrids are a massive success in the USA. We find out why that is, by testing the most popular American hybrid - the Toyota Camry Hybrid.

We also bring the latest offering from BMW, the ActiveHybrid 7. The other Beemer on the list is the soon-to-be launched i8 sports hybrid - the car aiming to become BMW's most compelling sports car.
