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.

New BMW Zagato Concept teased for Pebble Beach

A surprise new BMW Zagato Roadster Concept is teased ahead of a debut at Pebble Beach later this month. Following on from the BMW Zagato Coupe we saw at Villa D’Este earlier this year, BMW are now teasing what appears to be a Roadster version ahead of a debut at Pebble Beach later this month. A one-off collaboration between BMW and Zagato at Villa D’Este is one thing, but to follow that up a few months later with a Roadster version makes us think the protestations that the Villa D’Este car was a one-off were a tad disingenuous.

Motown rockers Dale Earnhardt Jr. Jr. serve up Horse Power

NASCAR fans looking for a new soundtrack to their auto-racing season can trade in their Lynyrd Skynyrd records for an offering from Detroit-based indie-pop duo Dale Earnhardt Jr. Jr. In a nod to their Motor City roots, band members Josh Epstein and Daniel Zott take the stage wearing racing suits and trucker hats and croon covers of Gil Scott-Heron's “We Almost Lost Detroit.” The band, which is touring the East Coast this week, released an EP titled Horse Power last summer and is coming out with its first full-length album, It's a Corporate World, on June 7.
