New Porsche 911 GT3 (991) technical highlights (video)

Ahead of its arrival with customers, Porsche has delivered a new video of the GT3 designed to make it clear just how some of its technical highlights work to make the GT3 swifter and more nimble than ever before. Power is of course the key to the GT3 – 468bhp and 324lb/ft of torque – but the power is no good unless the GT3 can put that power down as efficiently as possible in all circumstances. Porsche assert that the GT3′s chassis is engineered for Motorsport, and key elements of the new GT3 make it even more able.

Ram introduces CNG-powered pickup

Aside from the Honda Civic Natural Gas, compressed-natural-gas-powered vehicles have usually been converted after the fact, generally for fleet use. Chrysler is hoping to carve out a niche in the corporate-pickup segment by selling a factory-built CNG Ram 2500 that can seamlessly switch over to gasoline operation when the natural-gas tanks run dry. The twin 4.6-cubic-foot CNG tanks (which store the equivalent of 18.2 gallons of gas) take up a section of the bed, while an eight-gallon gasoline tank provides fuel during start-up and then reserve capacity when the compressed tanks are tapped out, allowing the bruiser a measure of operational flexibility.
