Bentley Flying Spur vs Mercedes-AMG GLE53

What's the difference?

In any other super car, it would seem deeply strange, wrong even, to loll (and LOL) in the back seats while a colleague blasts you around a race track at insane speeds, and not just because cars with V12 engines making 575kW and 1000Nm don’t normally have more than two seats.

The Bentley Flying Spur Speed is, of course, no ordinary car, it is a super sedan, a luxe limousine crossed with a rocket ship, and if Sir wants to get to the rooftop helipad in a spectacular hurry, then these are the back seats to be sitting in.

We flew to Japan, and the spectacular setting of the Magarigawa Club, a members-only race track carved out of the rolling hills outside Tokyo at a rumoured cost of $US2 billion, to try the back seats, and the driver’s seat, of the new and very impressive Flying Spur Speed.

You might have some traditional notions of what a 'sports car' is.

Low and light, slick and aerodynamic, purely mechanical and centred around the driver. These notions may have held true for a long time, but in an age where Lamborghini makes a Touareg-based super SUV is there room for those parameters to move?

Especially with consumer sentiment indicating the somewhat oxymoronic idea of a low-slung coupe SUV with an AMG powertrain is more than just a niche.

Mercedes told us the previous generation GLE coupe was a major success, amassing up to 25 per cent of the model line's sales split, and its research indicated  a buyer of this massive SUV was drawn to its "performance, style and technology" and was even "a motorsport fan."

Sounds like this buyer would have once been looking for a 'sports car' and like it or not, performance coupe SUVs are here to stay. But does the new GLE 53 Coupe really make for a compelling experience behind the wheel? We found out at its local launch.
