Bentley Flying Spur vs Mercedes-AMG GLC63

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.

It doesn't feel like that long ago I spent a day with the brand spanking new Mercedes-AMG GLC 63 S when it first arrived in Australia. It's a car that stuck with me, the SpaceX-worthy thrust of AMG's 4.0-litre twin-turbo V8 translating into that dirty V8 exhaust note.

Turns out it wasn't that long ago, but time waits for no car - the 2020 GLC 63 S has arrived, with some useful upgrades and a deep suspicion that someone, somewhere thought the car needed some changes.

And they may be right, because in June 2018, the GLC 63 S assumed an empty throne. Now in 2020, it has the Jaguar F-Pace SVR and BMW X3 and X4 M twins to deal with.

So, under a scorching hot Bathurst sun, I examined the box-fresh GLC 63 S for signs of nefarious activity, hoping things have not changed for the worse just because there are a couple of challengers in town.
