Audi says its new A7 combines the elegance of a coupe, the functionality of an Avant estate, and the prestige of a luxury saloon into one convenient package.

Reading between the lines, it’s difficult not to imagine that in trying to combine the qualities of three cars it will end up being slightly worse than all of them at those respective disciplines.

The company has surprised us in the past however and the original A7 remains one of the more successful proponents of the four-door coupe genre. In styling terms alone the latest A7 lives up to its predecessor, despite a this being a busier market these days, but style can only go so far – the A7 needs to work on the road, too.

Engine, transmission and 0-100km/h

At launch Audi will offer a pair of engines in the A7 Sportback, both displacing three litres, both V6, but one running on petrol and the other diesel. We’re familiar with both now, as they’re used widely elsewhere in the Audi range.

Both are competitive in terms of power and torque, the 3-litre TFSI (badged 55 TFSI) making 250kW and 500Nm of torque, and the 3-litre diesel (50 TDI) producing a lower 210kW but a meaty 620Nm. While both send their power to all four wheels, the route there is different for each. The TFSI gets a 7-speed dual clutch transmission, but the diesel, on account of its extra torque, uses the 8-speed ZF torque-converter auto used widely across the industry.

Those power figures are reflected in the cars’ respective performance numbers. The petrol is quickest off the mark, crossing the 100km/h barrier in 5.3sec, four tenths ahead of the diesel. Both are limited to 250km/h at the top end, and while combined economy and CO2 figures haven’t yet been confirmed for the diesel, the petrol is claimed to achieve 40.4mpg (on 19in wheels; 39.8mpg on 20in wheels) with 158g/km of CO2 (161g/km on 20s).
