What is it?
Audi’s good looking fastback coupé has been around since 2010 combining good looks, refinement and luxury in a package designed to rival the BMW 6 Series Gran Coupé and Mercedes-Benz CLS.
With a new A7 being penned in the horizon, the current five-door coupé’s range has been condensed to reflect its twilight years – with three core trims, supplemented by three 3.0-litre V6 diesel engines - while those craving a petrol version are limited to a 4.0-litre V8 powering the S7 and RS7.
On this occasion we are interested in the most powerful diesel on offer – the bi-turbo 3.0-litre V6, which on paper produces 315bhp and 479lb ft of peak twist pushing the Sportback to 62mph in 5.2 seconds and on to its 155mph limit. And yet it remains relatively frugal with a combined economy of 44.8mpg and produces 167g/km of CO2.
What's it like?
The engine shows all the signs of the potency its bi-turbo title indicates with the power arriving in two stages. Lowdown the 3.0-litre diesel is torquey and pushes you along smoothly but without the sudden urgency others give, before the turbos spool up and allows the A7 to rev more freely.
The engine cleverly flits between its two characters at a dab of the accelerator – from being a fast, quiet and smooth operator through to being a muscular feeling sports coupé. Such is the flexibility of this engine that no matter what your default driving action is the engine is happy to reciprocate. The noise is also rather good for a diesel engine with the V6’s vocals being rather pleasing on the ear, not to mention its visceral tones once you push on.
The Bi-Turbo A7 is fitted with an eight-speed torque converter automatic as standard compared to the dual-clutch units fitted to the other diesels in the range. The gearbox can feel a little sluggish to delicate accelerator inputs in first, but otherwise it’s quick to respond and switch ratios. It does like to hold onto a ratio far longer than its dual-clutch equivalents would but that does mean being able to exploit the torque available more readily.
Slot the hefty gearlever into ‘S’ and the gearbox transforms the A7 into the muscular sports coupé that its look and demeanour transmits, with the changes made snappier, and ability to reach the limiter under heavy acceleration before shifting up.
Even the ride is surprisingly good – seems crazy to say about a car at the luxury end of the spectrum, but let me explain. The Black Edition specification fitted to our test car, fitted the A7 with 21in alloy wheels, on lowered, firm suspension combined with standard steel coil springs.
Despite reducing the amount of travel in the suspension, it rides supremely well over the indiscretions littering the UK roads. Only larger potholes cause larger reverberations but a lot can be put down to the low profile tyres fitted.
The way the A7 steers is precise and predictable, providing all the assurances and confidence you would want when turning the wheel. However, if it’s feel and excitement you are after the A7 isn’t the car for you, as it can feel rather remote and detached.
