One Lap of the Web: Remembering Ayrton Senna

-- Hard to believe it's been 20 years since the passing of Formula One legend Ayrton Senna, but one Jalopnik reader remembers the bloody weekend in San Marino vividly. A dream vacation in Europe cumulating in the ill-fated Grand Prix: Alan Dahl saw Senna's wrecked car coming into the pits, but like the rest of the crowd, he wouldn't find out Senna's fate until he left the track. "For years afterwards I felt guilty that, not knowing that the tragedy had happened," he said, "that I had fun at the race." -- The excellent 8W, a site of racing driver stories, recounts the last 96 hours of Senna's life.

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.
