Bob Bondurant at 80

Last fall, as we waited for our turn to partake in a braking drill at Bob Bondurant's driving school in Arizona, a black Cadillac CTS-V coupe came screaming out of the facility's parking area and onto the tarmac where we sat. The driver hustled the big two-door around a tight autocross course at a startling pace, though he likely would have been faster had he avoided some of the smoky, sideways stuff. Our instructor, Johnny O'Connell, grinned, “I guess it's good to be the boss.” Bondurant -- who turns 80 on Saturday -- started racing an Indian motorcycle as a teenager.

VW Golf GTI priced from £25,845 in UK

The new Mk7 VW Golf GTI is now on sale in the UK priced from £25,845. That's only a £195 rise over the old Mk6 Golf GTI, despite the extra power, performance, and a 2.2mpg improvement in economy. Hang on - nearly £26k for a VW Golf GTI is a bit steep, isn't it?  Actually, it's better value than the old Mk6 Golf GTI. For a start, the new Mk7 Golf GTI's 29E insurance group rating is five groups lower than the old model's, so you should save on premium renewals as well as road tax and fuel fill-ups.

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.
