At first glance, it may seem unfair to pit a Bentley Flying Spur against Aston Martin’s snarling, AMG-powered DBX707. The SUV is named after its prodigious amount of power, after all. But it’s a closer race than you might think.

The premise is this: The DBX707 is the most powerful four-door vehicle Aston Martin sells and the Flying Spur W12 is the most powerful four-door vehicle Bentley sells in Europe. Since both are British luxury brands, why not see which is the quickest through the quarter-mile?

Despite those similarities, however, there are some differences. Powered by a 4.0-liter, twin-turbo V8 sourced from Affalterbach, the Aston Martin makes 697 hp (520 kW/707 PS) and 663 lb-ft (900 Nm) of torque.

The Bentley, meanwhile, gets more cylinders, but less power. Under the hood lies a massive 6.0-liter W12 engine that makes 626 hp (467 kW/635 PS). It is a torquey beast, though, and makes 663 lb-ft (900 Nm) of torque, just like the DBX707.

That power proves pretty useful when it comes to lugging around all of the wood, leather, and sound-deadening equipment that makes this four-door limo the luxurious experience that it is. Even though it’s a sedan, it weighs 5,373 lbs (2,437 kg), 424 lbs (192 kg) more than the 4,949 lbs (2,245 kg) SUV.

Despite weighing more and generating less power, though, the Flying Spur acquits itself pretty well in this race. Capable, first of all, of doing a surprisingly good burnout, the W12 is a little more raucous than one might have, at first, expected.

Indeed, its torque helps it get off the line really well and in two of three races, it gets the better launch. The Aston Martin‘s lower weight and extra horses, however, mean that it can reel in the Bentley in all three races.
