This is the new Mercedes-AMG S 63 E-Performance, a plug-in hybrid that features a 761-hp 4.0-liter turbocharged V8. It can hit 62mph (100km/h) in just 3.3 seconds, all while offering some of the best luxury features in the business.
Mercedes-AMG S 63 E-Performance Does 0-62 in 3.3 Seconds
The closest a Mercedes S-Class normally gets to Formula One is chauffeuring drivers to the track, but Mercedes-AMG says F1 tech tricks help make the 2023 S63 E Performance the most powerful S-Class ever.
While the latest AMG C63 S downsized from a 4.0-litre V8 to a hybrid-equipped four-cylinder engine, its S63 big brother sticks to its 4.0-liter guns, and adds hybrid power on top in the form of an electric motor on the rear axle.
The battery mounted above that axle is small at 13.1 kWh, and provides an unimpressive 21-mile (33 km) range, though it could be worse – the C63’s tiny 6.1 kWh battery only allows 8 miles (13 km) of Zero emissions driving. AMG claims the focus wasn’t on range, however, but performance, and the S63 certainly delivers plenty of that.
The old post-facelift 2017-20 S63 made 603 hp (612 PS) and 664 lb-ft (900 Nm), and the 2023 car’s V8 makes exactly the same. But by the time you’ve factored in the 187 hp (190 PS) from the hybrid system you’re looking at a total system output of 791 hp (802 PS) and a massive 1,055 lb-ft (1,430 Nm) of grunt. There won’t be a V12 S65 this time, but it’s possible Mercedes could liberate even more muscle from this hybrid setup to create a V8 S65.
Makes the V12 Maybach look underpowered
The 4Matic all-wheel drive version of the old car could get to 62 mph in a surprisingly rapid 3.5 seconds, and despite having almost 60 percent more torque the new one only snips two tenths from that figure – blame the hefty 1,157-lbs (525 kg) increase in curb weight to 5,556 lbs (2,520 kg).
But a 3.3-second 62 mph time still puts it a massive 1.5 seconds ahead of the 496-hp (503 PS) S580 and even 1.2 seconds in front of the 604 hp (612 PS) Mercedes-Maybach S680, the only S-Class still to offer V12 power. Top speed is limited to 155 mph (250 km/h) by default, but that can be raised to 180 mph (290 km/h) by throwing money at the options list and speccing the AMG Driver’s Package.
Air suspension with electromechanical anti-roll bars, adaptive dampers, rear-axle steering, carbon ceramic brakes and even active engine mounts, on the other hand, all come fitted as standard. That’s the kind of kit list you’d expect to find on an AMG sports car, not a luxury sedan, but the guys in Affalterbach are determined that the AMG-ness in the new S63 goes beyond the Panamericana grille, which makes its S-Class sedan debut.
Other AMG-specific visual tweaks include the “jet-wing design” front bumper with its large side intakes, trapezoidal tailpipes set either side of a diffuser, forged alloy wheels measuring up to 21-in in diameter (20s are standard) and a red-accented “S63” badge on the trunk lid.
Still a luxury car at heart
The four-seat interior gets a subtle AMG makeover, too. The S63’s luxury leanings mean carbon buckets are out, but the chairs do get bespoke AMG upholstery and stitching, plus AMG logos on the headrests, and the MBUX infotainment system and digital instrument cluster also feature AMG branding and unique performance-style displays.
There’s also a subtly-different AMG steering wheel with controllers to cycle between the four levels of brake regeneration and seven Dynamic Select driving modes. Those driving modes range from Sport and Sport+ that always keep the V8 in play, to Electric, which keeps it permanently disengaged while replacing the combustion growl with a low-frequency electronic rumble that can be heard both inside and outside the car at low speeds, and inside at higher speeds with flick of a button on the steering wheel.
Beneath the AMG makeveover and performance pretensions the S63 is an S-Class at heart and comes only in comfy long-wheelbase form, and with all of the luxury and safety equipment we’ve come to expect from the legendary limo. So there’s active distance control and steering assistance not just on motorways, but on open country roads without markings, and evasive steering assistance to help you swerve around pedestrians hell-bent on getting mowed down.
Curiously, Mercedes’ Drive Pilot Level 3 autonomous system, which is already available to order on the regular S-Class in Germany, and will soon be rolled out to other regions, won’t be available on the S63 until several months after it goes on sale next spring. The system allows drivers to travel along certain sections of road at up to 37 mph (60 km/h) while watching movies or working.
Mercedes hasn’t released prices for the new S63 E Performance, but considering the old S63 cost over $150k when it went off sale in 2020, the eventual sticker is going to be a hell of a lot closer to the $184,900 of the Maybach S580 than it is the $117,700 of the regular S580 4Matic.
Not cheap then, but the S63 doesn’t have a ton of direct competition if you still prefer combustion power to pure electric. The Bentley Flying Spur does luxury but is far less powerful, as is the BMW M760, and BMW has ruled out an M7. What would you pick? Leave a comment and let us know.
