CAR's rating:
This is the Mercedes-Benz AMG SL65 Black Series, the star of CAR Magazine’s December 2008 cover. CAR was invited to an exclusive test drive of this outlandish machine on road and track at Mas du Clos, France. Just 350 SL Blacks will be produced, with only nine coming to the UK.
We’ll deal with the road test here, but you’ll read what it’s like to drive flat-out on track – as well as an exclusive interview with AMG boss Volker Mornhinweg and his amazing plans for AMG diesels, hybrids and the new Gullwing supercar – in the magazine.
How much is the Mercedes-Benz AMG SL65 Black Series?
You’d better take a seat. Prices aren’t yet confirmed, but UK customers might pay as much as £250k.
But remember, even the standard SL65 comes in at £154k, and the Black Series is a massive, low-volume re-engineering job. The folding hard-top has been ditched in favour of a carbon panel that’s been bonded in place, upping rigidity and lopping 250kg off the kerbweight which falls from 2120kg to 1870kg. Of the other panels, it’s pretty much only the doors that are carried over from the standard car. The other parts – the front wings, the front bumper, the aggressively scooped bonnet, the rear arches, the bootlid – are all ultra-strong, ultra-light and ultra-expensive carbonfibre composites. Even the rear screen and rear side windows are new, replaced to improve aerodynamics and create a more coupe-like profile.
It’s not, erm, black...
The Black Series moniker came out of a dinner that AMG held for key customers prior to the 2006 Chicago motor show. These people usually had a number of AMG products in the garage, but turned to other manufacturers for hardcore thrills. Black Series products meant they would no longer need to. The name, says AMG, suggests the pinnacle of the range, much like American Express’s most exclusive credit card and other premium products.
So, you can order Obsidian Black, but you’ll also choose from Iridium Silver, Paladium Silver, Fire Opal Red, Diamond White and Tenorit Grey.
These bulging panels are all very well, but what’s underneath?
The standard 6.0-litre twin turbo V12 is boosted from 612 to 670bhp thanks to improved cooling and larger turbos. Torque remains pinned at ‘just’ 737lb ft because the standard five-speed auto can’t cope with the there-for-the-taking 885lb ft. Apparently an extra 50bhp would be an easy tweak too, with no negative consequences for reliability. A stronger seven-speeder is in the pipeline, but it won’t see service in the Black, which makes do with revised software and an uprated hydraulic system to deliver 25% faster shifts.
The suspension, meanwhile, has been fettled by motorsport-proven experts KW. It’s not adjustable in-car, but it is a fully adjustable set-up that can be tailored to your requirements. New wheels were naturally required to fill those gaping arches (relatively narrow 265/35 ZR19 Dunlop SP Sport Maxx GTs up front minimise tramlining at the expense of a little understeer, 325/20s at the rear give the SL some hope of gaining traction). Yet the brakes remain standard, AMG claiming that the weight loss more than offsets the extra horses the stoppers have to restrain. Fewer kilos no doubt also help account for the marginally improved mpg.
What’s it like inside?
Surprisingly luxurious, with leather and Alcantara and fillets of carbon trim. The main clue to this car’s track-honed origins is its fixed-back bucket seats and the airbag-free, carbon-lined door cards. The seats are still comfortable, but they don’t offer quite as much lateral support as you might expect. Yet the majority of cars will retain the standard chairs, the 200 US-bound examples forgoing the trick, airbag-free seats and door cards to meet strict domestic safety regs.
