Hanging onto the steering wheel for dear life while mumbling expletives is not what you imagine when you think of driving an S-Class. However, when it wears a ‘63’ badge, things are slightly different. More so when that badge gets red highlights, because that means the S-Class in question isn’t the usual, sophisticated, good boy, but its evil cousin. The Mercedes-AMG S 63 E-Performance is an 802hp limousine that is ready to rip a hole through time, and as its name suggests, it’s all about the performance. For once, the back seat takes a back seat in an S-Class.
Mercedes-AMG S 63 powertrain and performance
The S 63 is a plug-in hybrid gone rogue. It gets a 4.0-litre twin-turbo V8, putting out 612hp and 900Nm, but then a 13kWh battery and electric motor on the rear axle put out an additional 190hp and 320Nm, bringing the total output to a hysterical 802hp and 1,430Nm. Deploying 1,430Nm of torque to the tarmac is like putting Usain Bolt on your home treadmill. There is so much grip that it feels like the car is trying to stretch the road beneath it every time you put your foot down. As a result, despite its 2.5-tonne heft, it can go from 0 to 100kph in just 3.4 seconds. The top speed is limited to 250kph, but if you opt for the Driver’s Pack, you can remove the limiter and get it up to 290kph. Clearly, range is not the priority for this hybrid.
The numbers on the S 63 are intimidating, to say the least, and the experience from behind the wheel is, too. The car picks up the pace with zero lag, and you need to keep an eye on the speed readout; otherwise, it’s just a blur as you accelerate.
What helps bring this earth-shattering performance to the road are two transmissions. The engine uses a speedshift 9-speed MCT, and the motor gets its own 2-speed transmission, because it spins at a different RPM from the engine. First gear on the motor is good enough for up to 140kph and only after that does it switch to second for a smoother torque transition.
What you’ll be using most is the 9-speed with its paddle shifters. Needless to say, it is extremely responsive, and in Sport and Sport+, it’s extremely aggressive as well. When you push the car hard, shifts are immediate, and for total control, you can switch to ‘M’ or manual mode, where it will not upshift unless you tug at the right paddle. However, for everyday driving in the city, it isn’t the smoothest. There are noticeable jerks at low speeds, and even in Comfort mode, you’re constantly made aware of the massive power waiting to be unleashed. Then there is the exhaust, which, sadly, isn’t all-natural. A lot of it is fed through the speakers, and for the most part, you’ll barely hear it outside. Rev it high enough, though, and the V8 roar is very much there, along with pops and bangs that add to the drama.
We’ve seen this powertrain in the GT 63 S E-Performance, where it had even more power (834hp) but a smaller (6.7kWh) battery. The S 63’s larger 13kWh battery results in a higher claimed electric-only range of 33km.
Mercedes-AMG S 63 hybrid technology
The 13kWh battery pack uses Formula 1-derived tech and contains 1,200 individual cells that have a dedicated coolant line for thermal management. Not only is that better for packaging, but each cell can also be cooled individually, so you can push the car and not worry about overheating the battery. There are four recuperation modes—varying the level of regen—and you can charge the battery using a Type-2 port and the onboard 3.7kW AC charger.
Exclusive to the S 63 is a ‘B’ or Battery Hold mode that helps preserve the SOC. This allows you to switch to the all-electric ‘EL’ mode in heavy traffic and save some precious high-octane fuel.
Mercedes-AMG S 63 ride and handline
Because this is an AMG S-Class, there are two contrasting ideologies at work—sportscar handling and luxurious ride comfort. If you want S-Class levels of soft and supple, this won’t do the trick. The ride is inherently firm, and although it gets adaptive air suspension, you will feel jitters in the cabin even in Comfort mode. It also gets active engine mounts, which help keep things composed, and once you find a winding ribbon of tarmac with long swooping bends, the AMG side of the dynamic package is really felt. That said, on our bad roads, the one thing that you absolutely have to be aware of is the low ground clearance. Sure, the air suspension has a raise function that helps you gain some crucial millimetres, but you still have to crab crawl over big speed bumps to avoid grazing the underbody.
In terms of handling, you don’t really expect big things from an S-Class, but AMG’s pedigree clearly flows through this car’s veins. The 4Matic+ system, along with 3-degree rear-wheel steering, makes a huge difference in the bends as well as in U-turns and three-point turns. Despite having the same long 3,216mm wheelbase as the standard S-Class, in the corners, it is agile and sharp.
However, in seriously tight turns, its 2.5-tonne weight is what pulls it down, and at such points, all that handling tech can only do so much.
Mercedes-AMG S 63 design
In terms of design, there are many telltale signs of it being an AMG. Edition 1 gets the ‘Night Pack’ that replaces every inch of bling with blackened bits and the ‘Carbon Pack’ that adds racy carbon-fibre elements to the air dams, splitter, side sill, mirrors and diffuser. Apart from that, it gets sporty bumpers with huge air dams, the massive ‘Panamericana’ grille and an AMG logo in place of the Mercedes-Benz emblem. There are also 21-inch wheels wrapped in Michelin Pilot Sport 4 tyres and carbon ceramic brakes (standard on the Edition 1).
The rear, which many will find themselves looking at, features quad exhaust tips and red highlights for the badges, letting everyone know that this is an E-Performance and something that’s not to be trifled with.
Mercedes-AMG S 63 interior and features
On the inside, the S 63 prides itself on its AMG roots with a healthy dose of carbon fibre. The dashboard gets a carbon-fibre slab with a red weave within. The upper half also gets red stitching along with Nappa leather seats, which, though sporty, are superbly comfy as well. The new bit is the performance steering wheel that gives it full-blown AMG cred. Wrapped in Alcantara and leather, its plethora of touch buttons might seem intimidating at first, but it doesn’t take long to get used to. The steering also features context-sensitive AMG knobs that feature shortcuts to adjust the suspension, gearbox, drive modes and even the exhaust.
Also new are racier themes for the instrument cluster and telemetry, such as engine temperature, motor and battery readouts, and performance timing. The massive touchscreen in the centre is the nerve centre of the whole car, controlling everything from the AC to the chassis, and it’s super responsive. But rest assured, the screen has plenty of displays and data to satisfy your inner nerd.
The rear seat may not be the best seat, given this is an AMG, but it’s always going to be special in an S-Class. You have plenty of room to stretch out, and all the bells and whistles like seat massaging, heating and ventilation, along with the ability to move the passenger seat ahead and fully stretch out.
There is a superb Burmester 4D sound system, panoramic sunroof, incredibly comfy seats, rear entertainment screens, and even noise-cancelling headphones if the V8 is not sonorous enough for you. That said, with all that carbon fibre surrounding you and the grin on your chauffeur’s face, it won’t be long before you want to jump back into the driver’s seat. Also, since the S 63’s hybrid tech sits over the rear axle, the boot space is down to 310 litres, and you don’t get a spare wheel either.
Mercedes-AMG S 63 price
The S 63 E-Performance is priced from Rs 3.3 crore onwards, and the ‘Edition 1’ seen here, of which only three have been imported to India (and sold out), is listed at Rs 3.8 crore. It has supercar levels of power and all the luxury elements, and it is loaded with tech. Yet you’d struggle to justify the purchase. If you want a fun-to-drive car with lots of power, there are better options, and if you want a luxury car, the S-Class is already mighty impressive. It is difficult to see the logic, but as soon as you drive it, there is something about it that invokes your inner child. It won’t win track events or get you any drag race trophies. You won’t have a plausible justification. If you are the sort who looks for plausibility, this is definitely not the car for you. It’s a laugh, and you buy it because you can. If they ask you why you bought it, it’ll only take a quick spin to get them an answer.
