Bentley hasn't let much slip about the V8 that will be available in the 2011 Bentley Continental GT. However, each article that appears about Audi's use of the engine has one more little bit of information on it. According to what has been written we can piece together that it will be a 4.0-liter twin-turbo V8 with 550 horsepower. Bentley, though, hasn't given any indication of power output yet, though the 550 number was mooted in reference to next year's RS7 Sportback. If that were true for a V8 Continental GT, it could be uncomfortably close to the base V12 output.

Regardless, the latest news has the V8 will reduce CO2 emissions by 40 percent compared to the W12, listed as 396 g/km. Bentley said during the release of the second-gen Continental that the V8 would have "a class-leading CO2 emissions-to-power ratio," but even with that in mind, 40 percent is still a huge jump. Unless they're talking about simply piling on a huge amount of emissions equipment, there figures to be a serious rise in the Conti's EPA mileage rating, currently at 13 miles per gallon. It still wouldn't break 20 mpg, but it would be close closer, and not inconsequential.
