VW e-Golf & e-Up! electric cars Frankfurt debut

The VW e-Golf & e-Up! electric cars (pictured) will debut at Frankfurt.

Lamborghini reveals 2011's new V12 supercar engine

Lamborghini today announced the first details of its new V12 engine and transmission, which Lamborghini president and CEO Stephan Winkelmann promises will be 'the strong heart of the Murcielago successor next year.' It's to be the first clean-sheet Lamborghini engine since the original V12 first appeared in the 350GT, nearly 50 years ago. Lamborghini is keen to promote the low weight yet high performance of the new V12, which produces 700bhp yet tips the scales at only 235kg. Sant'Agata has also announced a new transmission for the Murcielago successor.
