Peugeot Onyx Concept: Paris 2012

The Peugeot Onyx Supercar Concept is a concept that will never be built and based on the underpinnings of the Peugeot Le Mans car. So Paris 2012 gets treated to the appealing Peugeot Onyx – a Gallic Jaguar C-X75, if you like – looking sexy and sleek on the floor in Paris with its copper and carbon fibre body and use of unusual materials like crystal glass and compressed paper. But it seems, as if we didn’t already know, that Peugeot aren’t planning to build an Onyx supercar – or at least not in their current financial muddle - and have even nicked its underpinnings from their own Le Mans 24hr diesel engine car to give the Onyx some eco and supercar credibility.

New Chevy pickup gets luxury trim

General Motors plans a luxury trim level for its next-generation Chevrolet Silverado pickup, its answer to the leather-swathed top offerings of its rivals. GM will name the model the High Country, according to dealers briefed on the plans during a national Chevy dealer meeting this month in Las Vegas. It's a response to the proliferation of high-end pickup models, such as Ford's F-150 King Ranch and Limited and Ram's Laramie Longhorn, which have sticker prices that can top $50,000.

A look at Cadillac future products

General Motors has green-lighted the development of a large flagship sedan for Cadillac, sources say, part of its plan to position its luxury brand's lineup to take on the German luxury stalwarts in every key sedan segment. The flagship sedan is to be built on a new rear-wheel-drive platform and arrive by 2015. The long-rumored rwd flagship would challenge the BMW 7-series and Mercedes-Benz S-class and is a key to GM's ambitions to expand Cadillac in China.
