Rolls Royce EX200 (RR4) about to surface
Tue, 10 Feb 2009There’s been a whole heap of shots of the new baby Rolls, the RR4 as it’s known internally, and we featured some last month. To add to the mix, we’ve also grabbed an interior shot of the new Rolls, which we reckon will be known as the Rolls Royce Ghost or the Rolls Royce Silver Ghost. But news has now arrived that Rolls Royce is actually planning on revealing the EX200 concept car at Geneva, which is pretty much what the new Rolls will be.
Sergio bows at Pininfarina Tribute Rally
Wed, 05 Jun 2013Pininfarina showed its Sergio barchetta concept at an event in the UK last week where the main aim was to set a record for the largest number of Pininfarina cars gathered in a single location. As Autoweek went to press, the total was nudging towards 200, an early audit of the delectable selection of machinery arranged on the lawns around Hurtwood Park Polo Club suggesting at least 180 cars with more still to report. “We're hoping to get over the magic 200, but will have to wait and see,” said Gary John on behalf of the organizers, Brokersclub.
Fiat 500 Abarth (2008): first official pictures
Wed, 20 Feb 2008By Tim Pollard First Official Pictures 20 February 2008 10:00 Watch out Mini, the Fiat 500 – CAR’s car of the year 2007 – is getting the high-performance treatment. The Abarth version unveiled today is pitched as a new interpretation of the Sixties road racer, but can they make a bigger, heavier hatch as exciting as that?The 500 Abarth 2008-style uses the Fiat group’s 16-valve 1.4-litre Fire engine breathing with the assistance of an IHI variable-geometry turbocharger to deliver a warm 135bhp at 5500rpm. So this car won’t challenge the upper echelons of hot-hatchdom that now have to pump out closer to 200bhp to be in contention.
