... Toyota's third-gen Prius... will somehow manage to be both more efficient and sportier. Toyota has had a few years now to tweak its Hybrid Synergy Drive and has created both performance hybrids and super-efficient hybrids from the technology. According to Toyota managing director Miguel Fonseca, the next Prius will emit less than 100 g/km of CO2 while offering sportier performance. The automaker could have gone even lower, and rumors indicate that a second, even lower carbon emitting model will in fact be available in Europe.
