Overall Track Performance
I think this is the perfect review for me to get back on the track after quite a break, as my absence seems insignificant to the paradigm shift that Mercedes-AMG has made in transforming the C 63 S E Performance.
Like for most people this is a shock to the system! Gone is the rear-wheel drive V8-powered monster that was such a raw and brutal driving experience, replaced with a 2.0-litre four-cylinder plug-in hybrid powertrain driving all four wheels.
This would have been an amazing head-to-head, old v new, but the memory of the outgoing model is still clearly embedded in my subconscious, and I knew the latest iteration would have to be something special to grab my attention.
Immediately on track it was a different experience, and it’s not just the sound or the power delivery. They are almost secondary to all the other changes that Mercedes-AMG has made. Dynamically it is a completely different package, more complete, more refined, more connected, and more sensible!
This is such a shift, that even Mercedes-AMG knows it won’t be for everyone. But in doing that, it has dragged the C63 S E Performance into modern times and beyond.
The outgoing model didn’t feel comfortable on the track – it wasn’t its natural environment. The outgoing model versus the BMW M4 Competition was an inevitable result when we last tested them together. Now the game is on as they have almost flipped roles.
Now the Mercedes AMG C63 S E Performance is so easy to drive fast on the track and with all the technology you only need to use a quarter of your mental capacity to lap faster than ever before.
Engine
As you would expect, base internal-combustion engine (ICE) numbers actually drop from 375kW to 350kW of power and 700Nm to 545Nm of torque; but when you add the hybrid technology total system output jumps to 500kW and a crazy maximum torque figure of 1020Nm.
The combination of technologies and power sources creates a strong linear power curve with instant and controllable response, using the engine, hybrid and turbo response system to cover the breadth of circumstances.
I find it hard to even to even put into words how well it blends everything together to make a seamless stream of energy.
Gone are the traction issues, replaced with pure acceleration and close to supercar performance. It’s a diametrically opposed experience that absolutely makes sense in outright performance terms.
The Mercedes-AMG C63 S E Performance has a claimed 0-100km/h sprint time of 3.4 seconds, which is half a second faster than the previous model but undeniably much more achievable, due to the traction and power delivery.
Braking
I had great confidence under braking and the pedal feel, travel and modulation was a step up on the outgoing model.
Because the chassis has improved so much, it also translates to an improved braking platform in turn inspiring confidence.
While I didn’t spend enough sequential laps to really gain an understanding of durability, the way I could modulate and control the release of the brakes on the way into the corner was excellent.
Chassis
This is a huge step up in terms of the dynamics of the Mercedes-AMG C 63 S E Performance overall, thanks in part to the ideal 50:50 weight distribution, combined with fundamental changes to geometry and technology.
The most impressive part is the increase in lateral grip, which builds up nicely as you rotate the car into the corner. The suspension arms are designed to flex under load, which widens the base of the car and adds grip.
Mercedes-AMG has also incorporated rear-wheel steer under 100km/h, which will help with rotation in the corner. Front-end grip is outstanding and when you push too hard, you are able to recover grip with ease and with limited loss of time. This increased flexibility of the chassis has elevated the potential of this car for all types of drivers.
If you think this almost sounds boring, you are wrong. The Mercedes-AMG C 63 S E Performance is potentially even more nervous and reactive than before, just without the rear end wanting to pass you every time your foot brushes the throttle.
It’s not a go-kart-like as the BMW M4 Competition, but I mean this in a good way, especially when living with a car on a day-to-day basis.
Transmission and Differentials
The Mercedes-AMG C 63 S E Performance has a nine-speed multi-clutch transmission that is engaging to drive, without ever being a hindrance on performance.
I don’t want to be too critical of the differentials, as I really didn’t have enough time with the car to explore the potential fully.
My initial feeling was that it is very well balanced and in control at all times, yet I would have loved the slightest tendency for the rear end to rotate on initial throttle, initiating a subtle four-wheel slide that I’m sure it is more than capable of.
As for traction and driveability, this was never an issue and with technology constantly assisting, there isn’t a lot for the driver to do apart from push on.
Suspension
The Mercedes-AMG C 63 S E Performance is more refined than before, offering sharp initial response but with more controlled movement than previously.
Mercedes-AMG has obviously been able to take advantage of the more equally distributed weight and power, to enhance the overall ride quality and grip.
Wheels and Tyres
The Mercedes-AMG C 63 S E Performance actually has slightly narrower front tyres, 265/35 R20 versus 275/35 R20 rears, using the Michelin Pilot Sport 4s.
These are a great tyre for a mixture of driving needs, and now with the improved chassis and drivetrain the stress on them is greatly reduced.
Driver Aids (Electronics)
Due to the fact I only had a handful of laps, I went straight to Race mode and got on with enjoying the car.
I never felt like the system was interfering with my driving and didn’t even need it to support me, because the underlying fundamentals of the car are so good.
Cockpit (Ergonomics)
The interior of the Mercedes-AMG C 63 S E Performance is excellent as always. The seats are comfortable and offer very good support on the track.
I absolutely love the carbon-fibre and Alcantara steering wheel. Its function, size and shape are spot on.
I like the mode buttons on the steering wheel, but would need to spend a whole day with the car and be someone with the technical knowledge of Paul Maric to understand the full potential of all the settings an options, including the power boost race track strategy, for the optimal lap time.
Lap Time
Unfortunately, the track layout we had to use on the day wasn’t our normal CarExpert circuit, so we don’t have a direct comparison. All I can say is this would be fast, and a lot faster than its predecessor!
But this isn’t even a fair comparison as Mercedes-AMG has taken what we knew as the C 63 and completely reimagined it. It may not be for everyone, but if you’re after a faster, more complete, more refined and more user-friendly package – it ticks every box.
While you may need to employ the assistance of a tech specialist to guide you through all the settings, the Mercedes-AMG C63 S E Performance is now an undeniably more complete car and brings an insane combination of everyday usability and track performance that so many can enjoy.
