The Audi Q4 will be launched in 2019

SUV will compete against the upcoming  GBMW X2, Range Rover Evoque and Mercedes-BenzLA. It is scheduled to follow the Q6 and Q8 into showrooms in 2019. Plans for the Q4 were originally revealed by Audi in the form of the TT Offroad concept, which first appeared at the Beijing motor show in 2014.

As with that car, the design of the production Q4 is set to include a heavily curved roofline and a lift back style tailgate. Inside, the Q4 is set to benefit from a range of developments already under way at Audi and parent company Volkswagen for inclusion the next generation of MQB-based models. These include full-HD instrument displays, gesture control functions, a 9.2in touchscreen navigation monitor, inductive smartphone charging and the latest connectivity features.

Among the powertrains earmarked for the Q4 is a new generation of four-cylinder petrol and diesel units that have a common 1.5-litre capacity. They will be joined by updated versions of today’s 2.0-litre four-cylinder petrol and diesel engines, as well as an all-new 2.5-litre fivecylinder petrol unit with up to 400bhp in a range-topping RS Q4 mode.  The new Q4 line-up will also feature a plug-in petrol-electric Q4 e-tron model with an electric-only range of up to 31 miles — as prescribed by China’s green vehicle regulations.
