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.

Nissan Juke R takes to the track on video

The road-legal Nissan Juke R may never be built, but today Nissan showed off its the GT-R-powered Juke performing on track.  It's a madcap one-off Juke pepped up with the GT-R's 523bhp 3.8-litre twin-turbo V6. The video below was recorded at the MIRA track in Warwickshire, as engineers had a chance to fine-tune the chassis.

Some Chevrolet dealers have stopped carrying the Volt after deciding that their sales didn't justify an additional $5,100 for tools to service the plug-in hybrid. Last month, General Motors notified Chevrolet dealers of the added cost for tools, among other requirements, to keep selling and servicing the Volt. The math didn't work for Allyn Barnard, owner of Jim Barnard Chevrolet in Churchville, N.Y., near Rochester.
