Much as I hate using topgear as a source this raised my interest considering current rumours:
For the avoidance of doubt I am not suggesting this TT is a mule for an f1 engine, just that there appears to be a chunk of synergy...under the bonnet is the same 2.5-litre five-cylinder engine from the RS3 and RS Q3, but boosted - thanks to a human-head-sized turbo - to nearly 600bhp, north even of last year's mad A3 Clubsport Quattro.
It's a trick turbocharger, too. Using a 48-volt electrical sub-system in the boot, the blower is electronically spooled to minimise lag. So even with a manual 'box, 0-62mph takes just 3.6 seconds and the top end is a bottom-clenching 193mph.
Reading too much into it? Almost definitely or perhaps not.
