Chrysler's new problem is a shortage of vehicles

A two-month factory shutdown and the cash-for-clunkers government rebates accomplished a feat that had eluded Chrysler Group: It turned several slow-selling vehicles into scarce commodities.

2014 Subaru WRX STI revealed – and it’s coming to the UK

2014 Subaru WRX STI revealed – and it’s coming to the UK We learnt last week that the new Subaru WRX STI was heading for a debut at the Detroit Auto Show and it’s now arrived, as has confirmation that the new WRX STI is going on sale in the UK too. Subaru UK has confirmed that because the Yen has weakened there’s now a strong enough case to put the new WRX STI on sale in the UK, and that it will cost less than the original list price of the old model at £28,995. The new WRX STI gets the familiar 2.5 litre four-pot delivering 305bhp and 290lb/ft of torque, sent to all four wheels through a six-speed manual gearbox.

Watch the Jaguar Project 7 F-Type go up the Goodwood hillcimb

Jaguar Project 7 F-Type (pictured) tackles the Goodwood FoS hillclimb One of the surprises of the 2013 Goodwood Festival of Speed has been the debut of the Jaguar Project 7 car, an F-Type with the more bountiful 542bhp supercharged V8 and styling stolen from the D-Type. Jaguar are saying Project 7 isn’t heading for production, but we’re pretty sure most of what’s underneath it – principally the 542bhp version of the supercahrged V8 – is in a production F-Type R. Perhaps surprisingly, fitting the 542bhp vresion of the V8 doesn’t seem to have done a lot for the F-Type’s sprint times, with 62mph coming up in 4.1 seconds, just 0.1 seconds quicker than the 495bhp engine in the standard Jaguar F-Type V8.
