It shows the exterior styling, advanced interior features, powertrain technology and various chassis developments set to be adopted by Audi’s future generation of production models, and is powered by a twin-turbocharged 4.0-litre V8 engine developing 597bhp (445Kw).
The concept is said to closely resemble the upcoming Audi A9 – a plush new flagship coupe planned to be launched in 2016 as a rival to the likes of the Mercedes-Benz S-class coupe.
With an aluminium and high-strength steel body, the concept is 40mm shorter and 70mm lower than the current A8, with official figures of 5100mm and 1390mm respectively, and is the same width at 1950mm. It also sits on a wheelbase that is 50mm shorter than the A8’s, at 2940mm, and gets 22-inch wheels.
Power comes from Audi’s twin-turbocharged 4.0-litre V8 petrol engine – as used in the existing A6, A7 and A8 as well as various Bentley models.
With drive channelled through an eight-speed automatic gearbox and Torsen four-wheel drive system, this provides the Prologue with a theoretical 0-62mph (100km) time of just 3.7sec, according to Audi’s own computer simulations.
As well as using a cylinder-on-demand arrangement that shuts off four of the eight cylinders on light throttle loads for added fuel efficiency, the engine also uses a 48-volt electrical system that should be adopted on the next A8 as part of a new raft of fuel-saving initiatives. The Prologue is claimed to return 32.8mpg (8.6 l/100km), giving it a CO2 emissions figure of 199g/km.
The new Audi concept also provides clues to the advanced chassis ready to be adopted by the new A8 and its more sporting A9 sibling; it uses a new five-link suspension with adaptive air springs capable of varying the ride height.
Inside, the dash incorporates a full-width instrument panel featuring an OLED display that enables digital interaction between the driver and front seat passenger.
According to Audi chiefs, about 80 per cent of the concept’s design will filter down into production vehicles. Three production cars based on the concept have been decided and will appear in the next two or three years’ time. The design of the next A6, A7 and A8, for example, will incorporate elements of this new design.
