Concept Car of the Week: Citroën C-Airdream

In the 1990s and early 2000s one of the most charismatic, brave and forward-thinking car makers, Citroën, had been reduced to the maker of budget, mainstream Euro boxes such as the Saxo and Xsara. The company hinted at its intentions to break free from its mundane existence as the maker of line-of-least-resistance rental cars with its Lignage concept in 1999 that harked back to its past large sedans, especially the CX. But it was at the 2002 Paris motor show that Citroën put a stake in the ground with its fabulously avantgarde Citroën C-Airdream concept.

Renderings hint at 2015 Ford Mustang appearance

We're still waiting to see what the 2015 Ford Mustang will look like. Spy shots only offer glimpses of undisguised sheetmetal between pieces of heavy camouflage, so until the debut, this set of renderings that appeared on Mustang enthusiast forum Mustang6G.com is the next best thing to an official reveal. Mustang6G forum member chazcron is responsible for the images, which are said to have been built from the growing number of Mustang spy shots circulating the Web.

Peugeot Unveils Hybrid Le Mans Racer

By Ben Whitworth Motor Industry 07 October 2008 13:03 Peugeot used the final round of this season’s Le Mans Series at Silverstone this weekend to show off its new hybrid-powered 908 HDi FAP racer, which features a similar kinetic energy recovery setup to next year’s Formula 1 system.The 908’s ‘HY’ undertook a number of demonstration laps in front of the packed grandstands and showed how Peugeot’s passenger car technology is filtering through to its motorsport activities.Over the weekend, the Automobile Club de l’Ouest – the company that runs the Le Mans series – announced a raft of aerodynamic and air-intake changes to next year’s regulations to even out the advantages of diesel over petrol. But rather frustratingly for Peugeot, there were no moves to incorporate hybrid powertrains in the 2009 season.But Peugeot claims that it will enter the 908 HY into next year’s Le Mans Series as a ‘Double Oh’ non-competitor to further evaluate the car’s hybrid technology.The HY’s layout comprises three key components - an 80bhp gear-driven electric motor-generator which replaces the conventional starter motor, 10 lithium-ion battery stacks to store the recovered power (six in the cockpit instead of the conventional battery and four on the left-hand side of the floor pan) and an electronic power converter, located in the rear part of the front left wing, which controls the flow of energy between batteries and motor.The result is a 3-5% mechanical energy recovery – and the associated economy and performance benefits. Over a single lap of Le Mans, for example, the system will recoup lost energy for up to 30seconds.This is then converted into a 20second 80bhp kick can either be meted out automatically by the car’s electronics to bolster acceleration throughout the lap or be selectively used by the driver using a ‘push to pass’ boost button.The additional and modified components add a further 65kg to the car’s weight, but Peugeot’s engineers claim the racecar will still easily meet the minimum regulated weight. “As a car manufacturer we can use motor sport as a research and development tool for the Peugeot brand as a whole,” said Michel Barge, Peugeot Sport’s director.
