The rich reserves are channelled to the rear wheels via a lightly revised seven-speed dual clutch transaxle boasting four modes – Comfort, Sport, Sport Plus and Manual. It receives the same updated software as that brought to the regular SLS AMG GT. The promise is a faster and crisper shift action and a double declutching feature.
Cosmetically, the last SLS AMG model gets a carbonfibre splitter up front and fixed wing at the rear – both taken from the SLS AMG Black Series, which also donates its carbonfibre bonnet with a central air outlet. Together, the exterior changes are claimed to reduce lift forces acting on both the front and axles while improving heat dissipation from the engine bay.
Further modifications include a set of forged aluminium wheels – 19in in diametre up front and 20in at the rear. They are shod with new Dunlop Sport Maxx Race tyres, which are described as being developed specifically for the range-topping Mercedes-Benz model.
Despite the adoption of these lightweight features, AMG quotes the same 1620kg kerb weight as previous coupé models, endowing this latest variant with a power-to-weight ratio of 359bhp per tonne.
Inside, the SLS AMG GT Final Edition receives quilted leather upholstery, carbonfibre trims and a liberal application of Alcantara – all from Mercedes-Benz’s Designo line of optional equipment. For all this you pay £189,880 in coupé guise as driven here, which seems excessive until you learn that early customers for the SLS AMG GT, without the carbonfibre exterior embellishments, trick wheels and more luxurious interior appointments, were originally quoted a price of £180,485.
What's it like?
First off, it handles the urban environment extremely well. The low end flexibility of the engine and automatic nature of the gearbox in anything but manual mode sees the SLS AMG GT Final Edition make light work of stop/start traffic, while the compliance of the suspension when set in the first of two settings for the variable dampers allows you tool around town without too much compromise in comfort. Yes, it’s firm, but it manages to swallow potholes without any real harshness at low speeds.
Still, it is out on the open road where the SLS AMG has always excelled, and the same holds true of this final variant.
The engine remains the main attraction, endowing the brawny two seater with truly impressive pace, both from a standing start and through the gears. The low end flexibility that provides it with such docile qualities around town is more than matched by the ability of the engine at the business end of the scale. From around 5000rpm, the big V8 comes alive. The changes made to the inlet manifold give it a more free-revving nature than earlier incarnations of the SLS AMG, bar the Black Series, and with it a more focused nature.
Official figures put the 0-62mph time at 3.7sec, placing the GT Final Edition among some fairly exclusive machinery in terms of outright acceleration. You need to be well on the way towards its 199mph top speed before experiencing the added downforce brought on by the aerodynamic changes. There is a noticable reduction in front end lift, with greater longitudinal stability when you’re pushing along, making it a more agreeable proposition at high speeds on Germany’s unrestricted autobahns.
It also possesses one of the finest exhaust notes ever. The big V8 emits a hearty baritone rumble at lower revs, growls with real intent through the mid-range and then explodes into an all-encompassing Nascar-like howl near its 7200rpm cut out. You’d buy one just on this quality alone.
