Remember the Shelby Series 1? The sexy sports car was the first and only standalone car developed by Shelby American. The company has now announced a conversion package that enables output to be more than doubled to 800 horsepower.

Chevy's redesigned Silverado 1500 has a six-strong powertrain lineup. One of the new options is a 3.0-liter turbocharged inline-6 diesel. It will be available early next year.

Volkswagen no longer sells a van in the United States, but the automaker has a good assortment in other markets. One is the California van designed for camping, and we just tested one on U.S. soil.
