Driving the 4.0L Petrol AT
The E63 S uses the M177 4.0L V8 engine, which made its AMG debut in the W205 C 63. In this car, it develops a whopping 604 BHP and 850 Nm, which is quite impressive. The M177 in the E63 S uses twin-scroll turbos as compared to the single scroll turbos in the C 63 S. In the E63 S, Mercedes 4MATIC system is standard, but it can now vary the torque split between front and rear axles by up to 100%. The claimed 0-100 km/h time is 3.4 seconds, and that is stupidly fast! This is quite a change from the previous E63 S, where the rear wheels would just be spinning well into 3rd gear.
The transmission used in this vehicle, along with a bunch of other AMG vehicles, is not a conventional torque converter transmission. In fact, it is not even a dual-clutch transmission. A little known fact is that Mercedes develops its own transmissions, and do not buy from other manufacturers like ZF or Getrag. The Mercedes 9G-Tronic MCT Speedshift transmission uses a multi-clutch system instead of a torque converter. And unlike a DCT, it has only 1 input shaft. The MCT system was developed in 2008 for AMG vehicles because a quicker shift time was needed than conventional torque converters, but the DCTs of the time could not handle the torque from the AMG engines. I do have to mention that this transmission is pretty quick when it comes to shifts, and Mercedes has got it pretty much spot on!
Sliding into the hard sports seats, I'm instantly reminded of the AMG GTR, because these seats seem like they are the same. The interior looks very familiar, except that unlike the other E-Classes sold in India, this doesn't feel like a limo thanks to the regular wheelbase. The carbon fibre all around and the quality Nappa leather feel really plush and sporty. And the flat bottom Alcantara steering is great to hold too. The startup is very tame, with not a lot of sound. At idle, the exhaust button didn't seem to make a large difference.
Driving inside the city is easy and the engine and transmission are tuned well in comfort mode and eco mode to suit traffic. There are no jerks, and in fact, it feels like a regular car completely. Even the refinement of the engine is impressive when it is not being pushed. The car does have a slight mechanical feel to it, which is nice and always desired in a performance machine. Torque is massive and even a slight dab on the accelerator is enough for most overtaking inside the city. Shifting into sport or race mode suddenly wakes the E63 S up. The suspension, steering, engine mounts, etc. all work together to suddenly make it feel a lot tighter. And if you put your foot down, my god! The torque from this engine needs to be felt. Its like it wants to rip up the tarmac with all 4 tyres! I daresay this felt a bit more brutal than the M5, even though the acceleration of both is pretty much the same.
Accelerating to a 100 is a joke, its over before you can even think about it. Beyond that also, it is insanely quick. I can't mention speeds here but let's just say the E63 S can give a lot of supercars a run for their money. The sound of the exhaust definitely improves when the engine is pushed. Beyond 3,000 rpm is when it really wakes up, and you do get a bit of the AMG growl. The E63 S certainly feels very tight when you're pushing it, and it feels far smaller than it actually is. It is extremely sporty! And the push in the back you get with the 850 Nm of torque is seemingly never-ending. Putting it in manual mode, with the traction on sport, and the drivetrain in race mode, was supremely fun and it was an awesome feeling to push it with everything seemingly synced so well. Now, it may be attributed to the worn-out tyres, but in spite of the 4MATIC system, the E63 S did have a wild kind of a feel to it.
Air suspension is available as standard. But if you think its a bit sloppy like air suspensions of yesteryear, you are wrong! The suspension is quite stiff. In fact, it may be a bit too stiff at low speeds. There is quite a bit of body movement, and all undulations and small bumps can be felt. The feeling was most probably exaggerated with the stiff optional seats, and possibly, the hard-worn tires. But it just didn't feel settled at speeds below 40 km/h. One big advantage with the air suspension is the option to raise the car, albeit by just 20 mm, but it still helps in clearing large speedbreakers or bad roads without worry. In terms of handling, the E63 is spot on. It is predictable, the steering feels well connected, and body roll is non-existent. It makes you want to push the car harder and harder. This is where I found that AMG has done the most catching up with the M cars - in terms of precision. On the highway, and at high speeds, the car is extremely stable, and bumps don't affect it a lot unless they are very large, and even the ride is completely flat.
The E63 S also does have a 'Drift Mode' which powers only the rear wheels. But again, like the M5, it means traction control is fully switched off. So you are on your own! I did actually go to a special place just to try this out, and boy did I have some fun. The pictures are further below in this post.
To conclude, the E63 S is truly a wild car and is extremely fast. Its caught up a lot in terms of handling ability and precision with the M cars, which is great! But it did feel to miss out on some of the everyday comfort which the earlier AMGs promised you along with stupid amounts of power. That said, it is by no means uncomfortable.
The speedometer is configurable. You can customize the type of gauges and what information is shown on the left and the right side:
This was my favourite speedometer view. There is an option of more conventional dials with a separate speedometer and tacho:
There is an individual configuration option for the drive modes. Its sort of like the M mode in M vehicles:
The next few shots are some sideways action at a special location which let us slide and slide till our desire was fulfilled. And that too without any wear on the tyres, since it was just loose sand. So no guilty feelings afterwards. I do have to mention that in drift mode, the E63 is very controllable and fun:
