Mercedes-AMG SL 63 S E-Performance - more muscle than fat
For those seeking a high-performing convertible, the Mercedes-AMG SL has been a source of joy for decades. But this time, with the SL 63 S E-Performance, the Germans have taken it to the next level. No other manufacturer offers a hybrid convertible this powerful - but then again, no one needs this much power.
It's already clear that we can't expect a completely laid-back product from the "SL" department, given that AMG has taken over the development of the luxurious roadster. It's been that way since the R107 (1971), with the model name suggesting a sporty-light vehicle, but it's more comfort-oriented with a tendency towards substantial weight. However, the newly released top model appears relatively trim at 2.1 tons. The emphasis is on relatively.
Let's just say, the adjective "athletic" fits here - this top SL has more muscle than fat. Under the hood, there's not only the familiar 4.0-liter V8 with 450 kW/612 PS, but also a compact electric power unit (150 kW/204 PS). Additionally, there's a two-speed transmission, which also has the potential to increase the weight.
Comparatively small battery
But there's a reason why this plug-in hybrid powertrain doesn't fare too badly on the scales. The battery is relatively small, at just over 6 kWh. And that shows that the top SL isn't primarily concerned with ecological issues, but with maximum performance. You might even wonder who would bother to charge the Benz externally, with just 13 kilometers of electric range.
Sure, the clientele with 223,720 euros in mind will likely park the open beast in a garage with a power outlet. But probably with the thought that it will then move forward as optimally as possible. But in the end, it doesn't really matter, because the eight-cylinder has no problem producing that little bit of electricity during moderate driving to store it in the battery and convert it back into propulsion when needed.
At least, that's the case when you choose the driving mode accordingly. Then, the V8 also delights with its presence, with a subtle rumble. And if you're driving aggressively, you shouldn't be surprised by fuel consumption of over 20 liters. You should consider whether the current road and traffic situation is suitable for a quick test of full throttle. Because with the combined 600 kW/816 PS (1,430 Newton meters of torque), this SL accelerates so violently that the previously distant front car suddenly seems much closer than you'd like.
Monstrous acceleration
That's a good point to bring up, because how much can one love a convertible that accelerates so monstrously that there are almost no words to describe it? Can too much also be too much? Sure, you can assume that the vast majority of customers won't constantly take advantage of the ability to accelerate from 0 to 100 km/h in 2.9 seconds. And reaching the top speed of 317 km/h is likely to be rare. In most cases, the feeling that the hybrid SL can be as brutal as it is will be enough. And of course, the certainty that you've bought the most expensive model.
We've long since lowered the electric roof and are enjoying the sun's rays in conjunction with the wind up front. To be honest, we could do with a bit more of that roaring. After all, we're forgoing raised windows and wind deflectors. But even in its most powerful guise, an SL is still more gentleman than rowdy - that's the preserve of British roadsters. You'd have to stay in the back to get more storm, but the space is only really suitable for children. The SL badge stands for 2+2 par excellence.
Relaxed Comfort Tourer with Power-Plus
Is there anything else to know? Certainly - namely that the particularly comfortable seats with their various high-tech functions (climate control and massage) match the semi-active suspension, which operates quite smoothly in the most comfortable setting. It compensates for any swaying movements on fast laps and a standard-fit rear-axle steering ensures sovereign cornering performance without making the SL feel hectic. It remains the relaxed comfort tourer - with the added extra portion of power here.
The question remains of how such a complex car can be operated. Traditionally, Mercedes does this quite well with voice control and, apart from that, with a responsive touchscreen and relatively few, but clear menus compared to what else is on the market. The large monitor unit can be adjusted in angle by an electric motor in case of unfavourable light conditions. Unfavourable is also the price of the top SL. But then, a dream car wouldn't be a dream car anymore.

Despite being a luxury convertible with a hefty price tag, the Mercedes-AMG SL 63 S E-Performance doesn't shy away from embracing hybrid technology. It's one of the few hybrid convertibles available that offers such extraordinary power, boasting a combined output of 600 kW/816 PS.
With its focus on performance, this SL model doesn't prioritize electric range, as its battery capacity is relatively modest at just over 6 kWh, offering only 13 kilometers of electric range.
