The range kicks off with the TDI Ultra Sport, which is powered by a 182bhp 2.0-litre turbodiesel, hits 0-62mph in 7.1sec and has a top speed of 150mph. It's by no means a slouch.
Next up in the range is the 178bhp 1.8-litre TFSI engine which is punchy enough to reach 62mph from standstill in 6.9 seconds, while the 227bhp, 273lb ft front-wheel-drive TFSI manual we’re testing, resident at the lower end of the model hierarchy but expected to account for a majority share of the sales mix. The flagship 2.0-litre TTS packs 305bhp and cracks 0-62mph in 4.9sec (4.6sec with S tronic gearbox) and is limited to 155mph.
Not much more than a decade ago, a claimed 0-62mph time of 6.0sec precisely would be enough to earn a coupé the label of junior supercar. But such is progress that today the performance claim applies to this least powerful of petrol Audi TTs. What’s just as remarkable is that it is supposed to achieve it despite the drawbacks of a manual gearbox, front-wheel drive and 'only' 227bhp.
Yet the TT is no slouch. Rain hampered its acceleration tests, but still it managed to reach 60mph in 6.6sec. For a better reflection of its performance, though, you have to remove the traction-limited sections of its run and compare it over, say, a 30-70mph sprint, which the TT completes in 5.0sec.
A previous-generation Porsche Cayman wanted hardly less, at 4.9sec. Left in fourth gear, the TT will reach 70mph from 30mph in just 8.0sec. The Cayman? It took 10.6sec.
