Numbers like this were unthinkable only a few years ago, but it’s amazing what a little federal regulation can do to spur an engineering department — or industry in this case.
It’s nothing new that automakers are making leaps and bounds in improving fuel economy while trying to maintain the power a larger engine can provide. The high-end luxury segment has been one of the last bastions of big engines and obnoxious fuel economy, but even Bentley is starting to come around.
With the latest numbers on its 2013 Continental GT Coupe and Continental GTC Convertible coming out, it looks like even the ultra-rich can appreciate saving a little gas. The V8 GT and GTC are new for 2013 and offer significant improvement over the 12-cylinder engine being replaced.
The V8 coupe gets 15/24 mpg city.highway while the convertible is 1 mpg less efficient around town. Those numbers represent a 25 percent gain, though the car is still subject to a $1,000 gas guzzler tax.
Unfortunately, lopping off those extra four cylinders means a drop in horsepower from 567 with the 6.0-liter twin-turbo W-12 engine to 500 with the 4.0-liter V8.
