The new 2015 Audi TT is on sale now ahead of first deliveries this December, with prices starting from £29,770.

Two engines are available initially, starting with a 2.0-litre TDI turbodiesel with 184PS and 380Nm of torque, fitted to an entry-level model Audi is calling ‘ultra’.

It can propel the TT ultra from 0-62mph in 7.1 seconds and boasts a 150mph top speed.

Respectable though those figures are, it’s the TT ultra’s efficiency that’s particularly noteworthy, with fuel economy of 67.3mpg on the combined cycle and CO2 emissions of just 110 g/km.

The other option is a 2.0-litre TFSI turbocharged petrol unit with 230PS and 370Nm of torque available from 1,600 to 4,300rpm.  In the front-wheel-drive TT, it completes the 0-62mph sprint in 6.0 seconds and has a 155mph top speed, yet can return 47.9mpg with CO2 emissions of 137 g/km.

When coupled with quattro four-wheel-drive and Audi’s six-speed S-tronic dual-clutch transmission, the same 0-62mph sprint takes just 5.3 seconds, although there is a marginal impact on economy at 44.1mpg and CO2 emissions of 149 g/km.

Two trim levels are offered – Sport and S line – with both featuring a 12.3-inch LCD display that replaces the traditional analogue dials in the instrument cluster, and offers a choice of display modes.

S line models receive larger 19-inch alloy wheels, LED headlights and tail-lights with sequential indicators, plus the option of a 10mm reduction in ride height.

A 310PS Audi TTS version will be available to order in October, with first deliveries expected in March 2015.
