SSC Ultimate AERO TT

SSC ULTIMATE AERO TT





D you want to drive fast? really seriously fast? you’re spoilt for choice at present – at least in terms of the machinery available, if not the roads to do it on... There’s the 253mph Bugatti Veyron, the 250+mph Koenigsegg CCXR and the Bristol Fighter T with a claimed top speed potential of 270mph, but which will be restricted to 225mph.
There’s also the Hennessey Venom Viper with a claimed top speed of 255mph.

The world’s most powerful production car, ever.
Boasting a truly gargantuan 1,183bhp, the small, little-known Washington State-based company claims a top speed capability of 273mph. In tests earlier this year on a closed section of Nevada highway the SSC managed 230mph in the two miles available, but had the originally intended 12 mile site not been hit by snow, then the Veyron could well have been humbled.

With strikingly rich paint, its all carbon composite bodywork looks like something from the mid 1990s.
There are echoes of Zonda at the front and Diablo at the sides, while at the rear function has priority over form.
There are noticeable variances in some panel gaps, but the giant alloys and big discs (more later) certainly look the part.

Despite the Aero TT’s massive torque, moving away sedately from a standstill requires a delicate balance of clutch and throttle.
It’s eager either to launch like a dragster, or stall. Despite SSC’s brochure claiming the TT’s rack and pinion steering is assisted.

On the road the SSC grips tenaciously. Its nose goes precisely where you point it, when you point it, and the steel tube chassis feels suitably rigid and well-balanced. I can only guess how the car might behave when pushed hard on a track, but with so much power, rear wheel drive and no electronic traction aides, considerable expertise, and prudence, would obviously be required.

Straight-ahead visibility is good, but the massive A-pillars can be a hindrance. Rear vision is effectively zero, save for the door mirrors and rear-facing camera with pop-out screen in the radio/stereo/satnav unit.
The adjustable suspension was set somewhere between firm and rock hard and so the ride was correspondingly unforgiving.
Driving one or more of those super-wide Michelins over cats-eyes sent loud staccato bangs and solid thumps directly into the cabin. At legal speeds the exhaust is quiet enough to allow conversation, but lifting off the throttle causes an almighty cacophony from the twin-turbo wastegates.
There’s the car’s throttle response, which is like nothing I’ve experienced before.
With just the slightest pressure on the pedal the car accelerates briskly.
With just a tiny bit more it surges forward with near-terrifying urgency.

Though the TT can deliver salt flat-shrinking speed, the brakes on this particular car are something of a mystery.
The brochure states that eight-piston calipers should be fitted at the front, but this one had four-piston units.
Pedal pressure required even from moderate speeds was inordinately high, with almost no feel or power.

And since when did all-American muscle have to dress up like posh European aristocracy? Some loud paint, serious wheels and an even louder V8 is all it really needs, and that’s what it’s got, in unprecedented abundance.
