Following this week's leak, Audi has taken the wraps off the Allroad Shooting Brake concept which points to the design of the upcoming third-gen TT.

Although in April last year we heard something about Audi's plans to revamp its styling language, the Allroad Shooting Brake concept doesn't have a groundbreaking design which indicates the next TT won't stray away too far in terms of aesthetics compared to recent models coming from Ingolstadt.

The concept seen here is 4200mm long, 1850mm wide and 1410mm tall, with a 2510mm wheelbase and 19-inch alloy wheels wrapped around in 255/40 tires. It tips the scales at a rather hefty 1,600 kg (3,527 lbs) and its body is made from a combination between aluminum and carbon fiber reinforced plastic (CFRP).

Its heart and soul is a transverse-mounted 4-cylinder, 2.0-liter TFSI turbocharged gasoline engine delivering 292 HP (215 kW) and 380 Nm (280 lb-ft) of torque. The conventional engine works together with a disc-shaped electric motor which provides an additional 54 HP (40 kW) and 270 Nm (199 lb-ft) and has been integrated within the e-S tronic six-speed gearbox. There's a second electric motor installed on the rear axle which offers 155 HP (85 kW) and 270 Nm (199 lb-ft).

Thanks to this hardware arrangement, the Allroad Shooting Brake concept offers a combined output of 408 HP (300 kW) and 650 Nm (479 lb-ft) and will complete the 0-62 mph (0-100 km/h) run in 4.6 seconds before hitting an electronically-capped speed of 155 mph (250 km/h). More impressive is the fuel consumption which stands at a very frugal 1.9 liters / 100 km (123 mpg US or 148 mpg UK) with CO2 emissions of 45 g/km while the maximum range is of 509 miles (820 km). It has an 8.8 kWh battery pack which provides enough juice for a maximum electric range of 31 miles (50 km).

The vehicle will be showcased starting Monday at the 2014 North American International Auto Show in Detroit.
