Plush new V12-engined, range-topping SL model boasts 621bhp and 737lb ft
4 April 2012

Mercedes-Benz has followed up the unveiling of the new SL63 AMG with a first look at its big brother, the mighty Mercedes-Benz SL65 AMG at the New York motor show.

The new range topping SL model adopts the aluminium body shell and other weight saving measures of its lesser-engined siblings in a move that has seen its kerb weight slashed by a considerable 170kg to 1950kg.

Under the bonnet resides a mildly reworked version of the old SL65 AMG’s potent twin-turbocharged 6.0-litre V12 engine boasting changes to its inlet and exhaust systems. Power climbs from a previous 603bhp to 621bhp on a band of revs between 4800 and 5400rpm, endowing the plush new two seat roadster with a power to weight ratio of 318bhp per tonne. Torque remains limited to 737lb ft between 2300 and 4300rpm.

Altogether, this represents a 91bhp and 111lb ft increase over the new twin-turbocharged 5.5-litre V8 powered SL63 AMG, or 64bhp and 73lb ft over the SL63 AMG running the optional Performance Package – something that is not offered on the SL65 AMG.

The revised V12 engine, which goes under the internal codename M279, drives the rear wheels via Mercedes-Benz’s 7G-Tronic seven speed automatic gearbox with a raft of BlueEfficiency features including automatic stop start rather than the two decade old 5G-Tronic used by the old SL65 AMG.

As a result fuel economy has been boosted by 17 per cent at a claimed 24.4mpg while CO2 emissions drop to 270g/km. Standing start performance is increased incrementally, Mercedes-Benz’s AMG division claiming 0-62mph time of just 4.0sec – 0.3sec inside the time quoted for the SL63. Top speed remains limited to 155mph.

Our Verdict

Mercedes-Benz SL

The Mercedes SL is perhaps the most splendid, single-minded luxury convertible in the world

Could do with a bit more grunt, couldn't it? ;-)

I've loved the glorious pointlessness of the various '65' engined cars, I'd glad they're carrying it on. I'm also glad they've managed to beef up the 7-speed enough to bring the everyday driving experience into the 21st century.

Unfortunately, these new 7-sp 65's will take a few years to filter through the used car network to the point it becomes attractive - like this:

Still not the looker it should be, the front is fat and slabby thanx to ped crash rules, The doors are ruined thanx to sprouting mirrors and the back is the only part that reamins ok.

The interior is a huge improvement over the outgoing model though, and if you buy one I expect you should use your keyless go, walk up to it eyes closed and only open them once inside.

Dont like side mirrors on doors (seems they're all at it now (shame on you Porsche). Funny coz new S Class (due soon) still has its mirrors in the conventional place not spoiling its lines, and the E Class has them in the corners too.

How bout the price ?

Will it tread on the " toes " of SLS sales ?

I dont think so.

Haha...yep I'm with you on that. 0-60mph in 4 secs, I need to go faster

It may be a technical masterpiece and no doubt it's well screwed together but it doesn't get the pulse racing does it ? More executive toy than fantasy car.

I have no doubt some people will knock it, but one thing I am sure of is this. Anyone not inclined to laugh out loud when they drive this car is reading the wrong web site. A hilarious mixture of good and barking mad.

All this does is highlight that both the AMG and non-AMG are criminally overweight for two seater cars. Frankly, this would be overweight for a minibus.

@Pepsi Max

You've obviously never driven one if you don't think it'll get your pulse racing.
