The new range-topping Mercedes-AMG S63 has been spotted testing. This V8 sporty limo is expected to come with a new hybrid engine when it goes on sale in 2021. 

  • 4.0-litre twin-turbo V8
  • Four-wheel drive
  • Hybrid tech
  • 700hp expected
  • Future S73 model with 800hp
  • Likely on sale in 2021
  • Expected to cost more than £125,000

The all-new, ultra-high-tech, seventh-generation Mercedes-Benz S-Class was unveiled earlier this year and a high-performance AMG version has been spotted undergoing testing. It marks a departure for Mercedes’ in-house tuners because it’s AMG’s first plug-in hybrid.

The new S63 will feature AMG’s signature 4.0-litre V8.

Like so many other AMG products, the S-Class will be powered by a twin-turbo, 4.0-litre V8 engine. Where it differs from other 63 models (including the AMG C63, E63 and G63) though, is that it’ll also feature an electric motor alongside its V8 engine for the first time. The car will also have 4Matic+ four-wheel drive.

New hybrid tech could bump the S63’s power up beyond 700hp.

Early reports suggest that the electric motor in the S63 will produce around 136hp, combining with the engine to produce more than 700hp. A more powerful version will also be offered, possibly badged S73, featuring a 204hp electric motor, which will boost the total output to more than 800hp.

A future S73 model could have more than 800hp.

No performance figures have been announced, but you can expect the S63 to dispatch the 0-60mph sprint in the low three-second range. It’s possible that the S73 could dip below the three-second mark, despite likely weighing in the order of 2.5 tonnes.

A big grille and larger intakes will help you tell the S63 apart from the standard S-Class.

Despite the heavy camouflage worn by the prototype in the images here, you can clearly see that the new AMG S-Class will feature similar visual tweaks over the standard S-Class as other AMG models.

Up front, there’s a huge grille and a deeper bumper with a lip spoiler and assorted air intakes that’ll give it a much more aggressive look than the standard S-Class. Big multi-spoke wheels, deeper side skirts, a rear diffuser and a quartet of exhaust pipes are clear to see as well.

Lowered suspension and new alloy wheels are expected for this AMG-tuned S-Class.

The regular S-Class heaves under the weight of high-tech gadgets designed to make it very comfortable and super relaxing to drive. Four-wheel-steering and adaptive suspension connected to scanners mounted in the nose of the car see to that.

AMG’s engineers will leverage all that tech – and no doubt add some tricks involving the electric motors – to allow the S63 version of the S-Class to get down a twisty road indecently quickly for such a big car.

The interior will feature Mercedes’ voice-controlled MBUX infotainment system in its most advanced form, and there’ll be massage seats, multi-colour ambient lighting and a thumping, crystal-clear stereo to boot.

Expect the new S63 to go on sale in 2021. 

2021 Mercedes-AMG S-Class price and release date

The old Mercedes- AMG S63 cost £125,000, while the now-discontinued V12-powered S65 cost £186,000. Expect prices for the new AMG S-Class to be in the same ballpark, with a similar difference in price between the S63 and S73. Both should go on sale in late 2021 or early 2022.
