The standard 2.0 TT is itself quite a brisk device, well able to spin its front wheels in the dry if you turn of the traction control, so it’s as well that the TTS gets four wheel drive, because it is obviously quicker still. This is very accessible power too, the strengthened balancer shaft four reaching peak torque at a low 2500rpm and staying there all the way to 5000rpm.
Such is its enthusiasm that at times you must deploy deft footwork to avoid jerking changes, an issue completely banished if you go for the S Tronic version. That fat torque spread makes it effortlessly easy to surge across the countryside, the all-wheel drive system heightening the Audi’s reassuring aura of stability.
However, tight bends in the wet can trouble it if you’re over-ambitious, with understeer setting in pretty determinedly, if briefly because the ESP soon quells it.
That’s a bit of a surprise given that the quattro’s Haldex clutch has scope to send as much 100 per cent of the available torque to either axle, and that it’s quicker to react now that it uses an electric rather than a hydraulic pump.
But it’s not quick enough if our experience on this tight, sodden bends was a guide, extra torque reaching the rear wheels only after you’ve gone in briskly, backed off, and re-applied the throttle, the TTS then sitting on its haunches to slingshot, quite impressively, out of the corner.
There’s shortage of finesse here, and not as much feel as you’d enjoy in the quite closely priced Cayman either. The steering in the TTS is precise and its weighting, which varies with speed, is generally well judged, but it doesn’t offer the crisp feedback you’ll enjoy from the Porsche.
The TTS ride is firmer than you’ll experience in the standard car, and firmer still if you prod the sport button on the centre console, which stiffens the magnetic dampers to the point that the car bobs and jerks uncomfortably on motorways.
Firm ride apart the TTS is a civilised thing, the pleasure of sitting in that high quality, satisfyingly well-crafted cabin underscored by refinement that persists at speeds well into three figures.
Also mighty impressive is the combination of performance and fuel consumption delivered by this engine. True, it has the advantage of less weight to push around, but the combination of a 5.5sec 0-62mph time and a combined consumption figure of 29.4 mpg (and CO2 emissions of 191g/km) is a real achievement.
The engine is pretty civilised too, but you won’t be hearing particularly tuneful sounds from it because it sounds rather flat despite those quad exhausts.
If you’re after the best driving experience in this class, then you need to direct your money Porsche’s way, both the Cayman and the Boxster outpointing the TTS Coupe and Roadster on this score. If dynamics are less of a priority, then the TTS makes an excellent car to live with, its security, general agility, refinement and build quality all strong draws.
If Audi could apply some more of the dynamic polish that makes the R8 such a fine device this TT would be serious challenger to Porsche’s position. But despite these shortfalls, there will be plenty of buyers who’ll find it hard to resist the second most potent TT behind the outrageous TT RS.
