Porsche Cayenne S Diesel: The V8 diesel Cayenne arrives

Porsche has revealed the 2013 Cayenne S Diesel with a 4.2 litre V8 diesel offering 378bhp, 626lb/ft of torque and 0-62mph in 5.7 seconds. Back in April we reported that the Porsche Cayenne S Diesel was on its way with a V8 diesel engine to take on the BMW M50d and the upcoming offerings from Land Rover with a 2014 4.4 litre Range Rover Sport seeming a likely possibility. Now Porsche has caught up and revealed the Cayenne S diesel, which gets the 4.2 litre diesel V8 with a healthy 378bhp and a very useful 626lb/ft of torque, enough to scoot the Cayenne S Diesel to 62mph in 5.7 seconds – a bit slower than the M50d, but all that torque should make it feel at least as lively.

Bentley brings even faster Continental V8 S to Detroit

Bentley first showed the Continental V8 S at the Frankfurt Motor Show a few months ago, but the slightly more powerful V8 Continental makes its North American debut in Detroit. More horsepower is always welcome, and the handsome new grand tourer delivers precisely 21 more. While Bentley has been concentrating on W12-powered Speed models -- even suggesting that it might be an entertaining drive on a racetrack -- the V8 range has been bolstered by its own modest performance enhancements: 21 more horsepower and 15 more lb-ft of torque bring the 4.0-liter engine's figures up to 521 and 502, respectively.

Renault Formula E racer (2013) at Frankfurt motor show

Formula E, the new elite racing series for electric single-seaters, has got the FIA’s backing, confirmed the major cities that will host the races, and now we've finally seen the crucial racecar. This is the Spark-Renault SRT_01E, a joint project developed between Renaultsport and Spark Racing Technology (SRT) which has just been unveiled at the 2013 Frankfurt motor show. There’s also been input from F1 legends Williams and McLaren, plus Dallara (which builds all the cars for the IndyCar series in the US).
