Rolls-Royce Ghost V-Specification dialed up to 593-hp

Just before a refreshed Rolls-Royce Ghost debuts at the Geneva Motor Show in March, the British automaker has rolled out a performance edition of its "entry level" sedan with 593-hp underhood. The standard Ghost sedan wasn't exactly short on power until the announcement of the V-Specification version -- the company's 6.6-liter twin-turbocharged V12 engine produces 563-hp and 575 lb-ft of stump-pulling torque in standard form. Yes, gone are the days when Rolls-Royce declined to disclose exact power figures and simply listed their powerplants' output as "adequate." Now Rolls-Royce is forced to compete in this cutthroat market with its performance stats, it seems.

GM says natural-gas Chevrolet Impala on the way

General Motors said it will sell a version of the Chevrolet Impala sedan with the ability to switch between gasoline and natural gas, part of the automaker's plan for taking advantage of a U.S. drilling boom that has made natural gas a more viable fuel for cars.

2015 Subaru WRX and STI prices revealed

Subaru enthusiasts will be able to get into a 2015 WRX starting at a base price of $27,090, including destination, for the standard six-speed manual model. That's a bit more than the 2014 model, which started at $26,790, but with Subaru’s entirely new platform, we’d like to think the extra $300 is worth it. This 2015 WRX will sport a 2.0-liter direct-injection turbo flat-four engine under the hood, making 268 hp and 258 lb-ft of torque.
