The current generation of the BMW M3 has been with us since 2007. As it nears a refresh, the company built a limited run of 200 special M3 coupe Lime Rock Park Edition cars to celebrate the racetrack in Connecticut. Skip Barber, owner of Lime Rock, and BMW collaborated on the vehicle, which will only come in what BMW calls fire orange.

Geely Englon TXN (w/ Gallery)

Geely is poised to show 39 new vehicles at the forthcoming Auto China 2010 motor show in Beijing, among them will be this new TXN taxi. While most of the new cars on show won't be built around entirely new sheet metal - some will feature new powertrains, for example - the Englon TXN is indeed all-new. Sitting in Geely's Englon range, a sub-brand initially created for the taxicab, the TXN is intended as a replacement for the aging TX4 built by British automaker LTI (as well as at Geely's Shanghai Maples factory).

Audi readies flagship Sport Quattro concept for Frankfurt

Audi will unveil its new Sport Quattro concept at next month's Frankfurt motor show, previewed in a number of sketches. We first saw the Quattro concept back in 2010 at the Paris motor show and three years later the carmaker has produced another iteration, a 2+2 coupé, that measures in at 4,699mm – 419mm longer than the Quattro concept (4,280mm). From what the sketches show, the Sport Quattro retains the chunky C-pillar of the 2010 Quattro concept, the 1984 Sport Quattro and the original Ur-Quattro models, while the four headlamp units are another nod to the original.
