The Audi Allroad Shooting Brake concept has been revealed at the Detroit motor show. Officially, Audi says that two-door crossover is a “concrete look into the near future”.
Unofficially, this car closely previews the exterior of the new Audi TT, as well as hinting that Audi may have finally given the green light to a two-door shooting brake version of the TT. The company previewed a very similar TT shooting brake concept nine years ago, but it failed to make production.
The Allroad Shooting Brake concept, which is just 4.2m long, has a skin made from aluminum and carbonfibre-reinforced plastics (CFRP). Although the production TT will be made of mainly aluminium, it is highly likely that a least one future high-performance TT will be partly constructed from CFRP.
It is powered by a hybrid e-tron transmission that, Audi says, combines a 2.0-litre TFSI petrol engine with twin electric motors built into the double-clutch transmission. There is also an electric motor on the rear axle, which, combined with the front-drive set-up, offers on-demand all-wheel drive.
This drivetrain is backed by an 8.8kWh battery, which is mounted forward of the rear axle to aid weight distribution. Audi says that it will allow up to 31 miles of pure EV driving.
At full bore, with the engine and electric motors driving the wheels, there is 402bhp of ‘system power’ and 480lb ft of ‘system torque’. Audi says that the show car weighs about 1600kg unladen but can hit 62mph in 4.6sec. Top speed is 155mph. Audi claims an official CO2 rating of 45g/km and an average consumption of 123.8mpg.
Audi states that the 288bhp/199lb ft TFSI petrol unit is a “high-end engine” equipped with a large turbocharger and both direct and indirect fuel injection. The exhaust manifold is integrated into the cylinder head for maximum thermal efficiency.
The Allroad Shooting Brake has three drive modes. In EV mode, the powertrain in the nose is idle while the rear-mounted axle powers the car up 80mph. In Hybrid mode, the various elements of the drivetrain “work together in various ways as necessary,” according to the manufacturer.
However, much of the time, the engine couples with the electric motors in the transmission to work as a range-extender, generating electricity to recharge the battery pack and power the rear axle motor.
In Sport mode, the TT’s ‘full system power’ is available as the engine and rear electric motor drive all four wheels. Audi says that when the driver releases the accelerator pedal, all drive units can be decoupled to allow the car to coast with minimal mechanical drag.
Speaking to Autocar at the Detroit motor show, Audi marketing boss Luca de Meo said: "The original Audi TT had a huge impact on the market and the image of Audi. We know the new car must be a leader in technology and design especially, and it is critical that the new car continues our success in the market."
