Jaguar XJ Diesel – The Swansong plaudit

The Jaguar XJ 2.7 Diesel has won the 'Greenest Luxury Car' Award And although one of the strengths of Jaguar has been its heritage it has, to a degree, also become its Achilles Heel. The first Jaguar XJs were a triumph when they were launched in 1968, and put Jaguar leaps and bounds ahead of the German competition, in the same way Jaguar had taken the world by storm with the E-Type a few years before. But things started to fall apart for Jaguar in the ’70s with the fiasco that was British Leyland, and by trying to emulate Porsche by making each iteration of the XJ an evolution of the original all they managed to do was cement in the public mindset the failings of the XJ.

McLaren 12C Can-Am at Pebble Beach

A (currently) one-off McLaren MP4-12C – the McLaren 12C Can-Am – is heading for Pebble Beach, previewing a track-day MP4-12C. The McLaren MP4-12C is a one-off track-focused MP4-12C, developed by the same McLaren GT team which developed the MP4-12C GT3 race car, and its heading for Pebble Beach this month to tempt US track-day enthusiasts. Developed without the constraints of a racing series, the 12C Can-Am is based on the GT3 car and adds a new aerodynamic package – which improves downforce by 30 per cent – with a carbon fibre splitter with little winglets atop, a huge rear tray of a spoiler and a carbon fibre diffuser.
