GM continues work on fuel-saving engine technology

Sometime in the next decade, you might be able to enjoy some of the benefits of a diesel without driving one. A technology called HCCI improves fuel economy 15 percent and releases fewer emissions by using a combustion process similar to what is used in diesel powerplants. General Motors continues work on the project, which could be applied across a range of engine sizes and used with other advanced fuel-saving technologies to help the company comply with the proposed new mileage and emissions targets announced Tuesday by President Barack Obama.

Aston Martin CC100 Speedster Concept celebrates Aston Martin’s Centenary (video)

Looking like a modern interpretation of the legendary AM DBR1 Le Mans car from the 1950s, the CC100 is a dramatic ‘Speedster’ concept powered by Aston’s latest V12 and makes its debut – driven by Ulrich Bez – at the 24 Hours of Nurburgring Race event in Germany today (19th May 2013). Aston put together the CC100 in less than six months (did no one tell them 2013 was Aston’s centenary year until last Christmas?), and roped in carbon fibre specialists Multimatic to create the body and interior from carbon fibre, and Aston Martin used the VHM platform to create the underpinnings for the CC100, and have powered it with the latest version of the V12 AM11 engine with a six-speed sequential gearbox. Chief Exterior Designer, Miles Nurnberger, said: The brief was very simple, yet enormously testing: create something that reflects the 100 years of Aston Martin heritage and signals the future of the brand.

Choice of UK police cars massively slimmed down

Car enthusiasts will soon be able to relax a little after it was announced that the range of police cars approved for use in Britain is being slashed. Those backward glances in your mirror will now be a simpler mental process. This week’s Government spending review will purge many of the wilder police cars favoured by some constabularies, as they launch a drive to save £3.4 million each year by standardising procurement of patrol cars.
