Drag race: Every Audi RS6 generation: C5, C6, C7, C8

The Audi RS6 is without a doubt a legend — you’ll be hard-pressed to find many cars that have so consistently delivered practicality and supercar-rivalling performance over the years.

It’s now in its fourth generation, and arguably it’s better than ever. With a 4.0-litre twin-turbocharged V8 producing 600hp and 800Nm on board, it’s no slouch and will scare some McLarens or Ferraris in a straight line.

But how does it stack up against its own bloodline? Well, today’s drag race pits each generation of the RS6 head-to-head to see which version of the powerful estate is the best of them.

Off the bat, you can guess the two that you’d expect to drop behind. The first-generation ‘C5’ RS6 may have kicked off a legacy, but its performance numbers are way down on what they are now.

Its 4.2-litre twin-turbocharged V8 puts out a subjectively meagre 450hp and 560Nm of torque, delivered through all four wheels through a five-speed automatic. It’s the lightest of the bunch though at 1,865kg.

Next up is the ‘C6’, which is a bit of an exception to the RS6 lineage with a 5.0-litre twin-turbo V10 on-board. It puts out 579hp and 650Nm, though weighs more than its predecessor at 2,025kg. It also sends power to all four wheels but through a six-speed automatic.

The car that should give the newest RS6 a real run for the money is the previous-generation ‘C7’, though. It uses the same 4.0-litre twin-turbocharged V8, with a touch more power at 605hp. It’s 750Nm torque figure is some 50Nm less than you get in a the ‘C8’ model, though.

That said the ‘C7’ is lighter than the ‘C8’ at 1,950kg compared with 2,075kg — and uses the same eight-speed automatic gearbox. Bit of a tough one to call, then.

Which Audi RS6 can lay claim to being the fastest of them all, then? You’ll have to watch to find out…
