Chevrolet is bringing CNG power to the Silverado HD

Chevrolet is taking CNG-powered vehicles seriously, with so many of their trucks being used in commercial fleets, so it was perhaps no surprise that we'd see a version of the 2015 Silverado HD that can be run either on gasoline or compressed natural gas before long. Chevrolet brought the 2015 Silverado 2500 HD CNG to the Chicago Auto Show, to let prospective buyers as well as the media to learn about at the savings that could be realized with this environmentally friendly setup. The HD CNG truck will offer bi-fuel capability coupled with its 6.0-liter V8 engine that's been modified with hardened valves and valve seats to run on compressed natural gas.

Renault Twingo Renaultsport (2008): first official pictures

By Tom Clarkson First Official Pictures 31 January 2008 18:17 Renault today unveiled its new 133bhp Twingo RS in Paris - with a little help from F1 stars Fernando Alonso and Nelson Piquet Jnr, who were in town for the launch of their R28 F1 car. The Twingo RS has a naturally aspirated 1.6-litre engine that produces 20bhp more than the 1.2-litre turbo of the Twingo GT. There are cosmetic differences between the two cars as well, such as extended front and rear wings, a rear spoiler and a lower front bumper on the RS.

But Hyundai are being pragmatic. There is a desire from the public for all electric cars – however misplaced that may be – and Hyundai aren’t going to be left out.
