Jaguar celebrated its 75th anniversary with a number of special models, including the fleet-footed XKR 75. And a British tuner is goosing this lithe coupe even more. Arden boosts output to 580 hp and 531 lb-ft of twist, while bolting on a high-performance exhaust system and sport catalysts.

New Ferrari California T gets new twin turbo V8 with 49% more torque (+video)

The new California T (pictured) revealed ahead of a Geneva debut It’s been a long time since Ferrari gave one of its cars a turbo charged engine, not since the late ’80s and the Ferrari F40, but that all changes – and no doubt points the way to the future – as the Ferrari California T gets revealed ahead of a debut next month at the Geneva Motor Show. Based on the V8 Ferrari build for the Maserati Ghibli, the California T’s new engine is a 3.8 litre twin turbo with 552bhp and a mountain of torque, 557lb/ft, a massive 49 per cent more than the current California produces. That improves performance marginally – 0-62mph in 3.6 seconds and a top speed of 196mph – but has a big impact on economy; the new California T improves on the current California by 15 per cent, recording official figures of 27mpg and 250g/km.

How Mercedes sees into the future

Mercedes' crystal ball is named Alexander Mankowsky. At 56, he's dressed for CES in khaki trousers and a leather vest, with thin glasses perched on a round face; his frizzy white hair resembles what Einstein's would if he were caught in a wind tunnel. He might be a long-distant uncle, or he might be Doc Brown, fresh from the DeLorean.
