The Roadjet is a hatchback/estate/SUV vehicle sized between the A4, with which it shares in underpinnings, and the A6. It measures 4.70m in length and 1.85m in width and in the metal it seems more like a big brother to the A3 Sportback.
Audi could opt to name the production model the A5 or keep the Roadjet name, but insiders say that this vehicle is probably not to getting the Q5 designation. The latter will be more of a baby Q7 and will rival the BMW X3.
However, the Q5, which is due for introduction in the next year or two, will also share its underpinnings with the A4 and Roadjet, but will be taller and more rugged.
The concept car seen in Detroit had a 220 kW version of Audi's 3.2-litre V6 FSI direct-injection petrol engine and a seven-speed DSG transmission.
