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.

NHTSA safety consultant dies at 64

Miami trauma surgeon and preeminent car-crash researcher Jeffrey Augenstein would often tell the story of the time he was talking to a crash victim who collapsed and died from hidden injuries in the middle of the conversation. The experience led Augenstein to research and then call attention to the unexpected injuries that could occur when drivers interacted with airbags. It's but one example of the achievements of Augenstein, who died recently at age 64.
