Driving the 4.0L Petrol AT
This S63 facelift has downsized from the 5.5L V8 to the 4.0L M177 V8 engine we have seen lately in all the 63 badged AMGs. Like the E63 S, this too has the variable scroll turbos and is pretty much identical in terms of setup to the E63 S, except it has 50 Nm more torque. What is different in this flagship model is the fact that it is rear-wheel drive. So there is 950 Nm and 612 BHP always going only to the rear wheels! The claimed 0-100 km/h time is only 3.5 seconds, which is surprisingly quick for a vehicle of this size. Even though it is a RWD, the S63 manages to almost stick to the claimed timing.
The transmission is the AMG Speedshift MCT 9G-TRONIC, and it is an upgrade from the 7-speed offered on the pre-facelift model. In terms of the way it shifts and behaves, one cannot fault it. While there may be some slightly better tuned transmissions out there, this is quick to shift and doesn't hesitate to downshift. It is almost as good as the BMWs. What I do like is how it feels absolutely smooth when left in Auto, almost like a regular S-Class. And once it is moved into Sport or Race mode, the shifts really quicken up. And the response to the paddles is almost instant too. What is annoying, like other AMGs, is how in Auto, it starts off in 2nd gear, but when in manual, the gearbox doesn't let you shift to 2nd before 17-18 km/h.
Getting into the car, it really does feel like the S-Class in terms of seat size and comfort. Unlike the C and E, these seats are very spacious and soft to sit on. The slightly different dashboard of the coupe looks awesome with the large trim pieces and the leather which can be felt literally everywhere. The interiors come together and look simply stunning! There is not a single person who saw the S63 and was not thoroughly impressed with the interiors. I think a lot had to do with the well-chosen Bengal Red leather and the carbon fibre trim.
Starting up, the engine emits a growl, which is enhanced when the valves are opened. Apart from that, the exhaust is not really loud, but it does give out some nice pops and bangs when its heated up and even more so when the car is running high octane fuel. Driving around in city traffic was actually a pleasure. Maneouvering the S63 in rush hour traffic was not difficult at all since the length is much more manageable than the sedan. With a massage on, and listening to music, you don't realise or really bother with what's going on outside. Also, this being in a rather subtle matte silver, it didn't get as much attention as would be expected with a vehicle of this price. There were no bikers going crazy, no people jumping in front to take a picture as might have happened with a 911 or an Aston Martin. In a sense, it is good, since one can enjoy the vehicle rather than concentrate and worry about people all around.
With the RWD, comes all the fun. The S63 is tail happy, and with all the torque, it had better be! When you put your foot down, it does get better traction than you would expect, and just gives you a solid shove into the seat and accelerate to insane speeds before you know it. With the traction control in Sport mode, it gets even more loose and sometimes needs a tiny bit of counter steer! But somehow, it manages all this while still being elegant in a way an S-Class should be. The highlight of this car for me is the huge amount of torque coupled with the rear-wheel drive. It never feels like there is any dearth of power, whatever speed the car may be at.
In terms of ride quality, it is plush even with the 20-inch wheels and low profile tyres. Its certainly not as good as the S-Class sedans, but it is still very comfortable and manages to absorb a lot of the small and mid-size bumps, provided the car doesn't go over them too quickly. The raise function is great as always, and with the suspension raised, the car did not scrape even once. I did have to take it sideways over the larger speedbreakers. But it cannot be called impractical, or unusable. It is very much possible to daily drive the S63. On the open road, stability is very good and you do not realise the speeds you are maintaining. It does have a tiny bit of waftiness associated with an S-Class, but also the firmness to keep up with the sporty pretensions of the S63. In Sport mode, it does feel a lot smaller and one does feel confident of pushing this into a corner. It is actually quite a chuckable vehicle, unlike the first impression it may give. I was very impressed with this, since the earlier S-Class Coupes (pre-222) are similar to boats! The steering feel is quite accurate, but when driving enthusiastically, it did feel a bit disconnected from the road at times in terms of feedback. But it does give you the confidence to push the car hard.
Being a flagship vehicle, the S63 was loaded with all the safety tech one could want. The radar systems for adaptive cruise control, which also help with the auto brake, blind spot monitoring, and cross traffic monitoring. Now in Mumbai traffic, the first thing I had to do when I switched on the S63 was to go to the assists menu, and switch all of them off. The assists, invariably, would kick in unexpectedly and scare the crap out of the person driving, and also the people around them on the road. While on the highway, or an open road, it is certainly great, inside the city, I believe it may cause someone to rear-end the vehicle with the sudden braking. Another scary experience was with the blind spot radar - I was driving very casually at about 70 km/h, sticking in my lane. I saw a biker speeding in between lanes who was going to overtake from the left, and as he was approaching, maybe the S63 felt he was going to hit because I suddenly felt the car go a bit to the right and brake on its own at the same time. I couldn't for the life of me understand what was happening and I thought I was going straight into the wall. It lasted just a second or two, but that was enough to scare me.
All in all, the S63 is definitely a vehicle I would want to buy if I had the money. It is something which can be called an all-round sports car. While it may not have the brand name of an Aston Martin (whom I consider the S Coupe's competitor), it definitely does have the special feel.
