Bye, Bye, Diesel: Mazda's United SportsCar Prototype Is Getting Gassy

We loved the Mazda6 Diesel race car that started off in Grand Am’s class for alternative fuels. It’s a diesel! So weird and quirky! Yeah!

Is This A Real Prototype Jeep Pickup, Or Just A Home-Made One-Off?

A reader spotted this single-cab Jeep Wrangler JK pickup truck with manufacturer plates in the Detroit area this morning. It's probably a product of the aftermarket, but maybe, just maybe, a Chrysler employee is field testing the very thing many of us have been dreaming of for ages: a modern, factory, Wrangler pickup. »8/22/14 6:28pm8/22/14 6:28pm
