2016 Mercedes-AMG SL 63 first drive

For those of you familiar with the glacial pace of Mercedes-Benz SL development, prepare to be alarmed. Just four years after it was launched, here’s the facelift. 

It’s okay, calm yourself. Mercedes clearly did. This is one of those mild tweaks, as befits a car that Mercedes, presumably, will be disinclined to throw vast sums of development money at because of the small numbers it sells in. Britain is its second-largest market, where fewer than 1000 of them a year find owners. 

So, mild facelift it is. Most notably, the front – the face, if you will – has been, er, lifted. It’s now a bit more reminiscent of both the rest of the current range and the first SL, the racing one that the modern SL doesn’t otherwise particularly resemble. AMG’s GT is Merc’s racy car these days, the SL is a luxurious two-seat roadster, even when equipped with a 5.5-litre, twin-turbocharged V8 that puts out 577bhp. 

The other options are an SL 400 (a 3.0-litre V6), the SL 500 (a 4.6 V8) and the AMG SL 65, which has a 6.0-litre V12. All of those have two turbos apiece because, let’s face it, a 6.0-litre V12 wouldn’t be sufficient without two turbos.

The 63, though. At £114,100, do you need it over a £73,805 SL 400 or the £82,850 SL 500? Unlikely, although somehow a car like the SL feels like it wants a V8, and if you’re going to have a V8, then I’m inclined to think that it’s worth having one that somebody has made as rowdy as the AMG engine. 

The 63’s motor makes 577bhp which, when driving an 1845kg car, means performance is fast-sports rather than supercar quick. It can reach 62mph from rest in 4.1sec and is limited to 155mph. All versions do it in four-point-something, mind you, so none is slow, but only one makes this sort of noise. So it sounds like a sports car. Does it drive like one? 

The SL 63 will do a passable impression of a sports car. Don’t think that it ever rides anything other than well – no matter whether you put its adaptive dampers into their sport or comfort modes – while truly agile it is not. But it is willing, and bear in mind what this car is asked to do: it weighs nearly two tonnes because there is a roof in place, making it almost as quiet as any coupe in the district. That roof can be lowered into the boot in 18 seconds.

And while, yes, it has only two seats, they are impeccably comfortable and electrically adjusted. Interior fit and finish are superb too, and there’s lots of kit to fit and finish in here. The SL is, for all intents and purposes, a luxury car. It is the kind of car that you’d look forward to sitting in every day of the year. If it did an even passable impression of what a sports car is, then, that would be no unremarkable achievement.

It does rather better than passable. Engine response, despite two turbos, is good: although the automatic gearbox presumably masks some of it. The AMGs get seven-speed transmissions (although they’re each different from each other; the 63’s has a wet clutch and the 65’s is a torque converter) rather than nine-speed torque-converter units that the 400 and 500 have just adopted.

The 63’s shifts well enough left to its own devices, but is less crisp than the eight-speeder of, say, a Jaguar F-Type. Ditto throttle response. Pull shifts yourself though and, occasional obstinate downshift aside, it’s on your side.
