2016 Audi Q5 spotted with new grille and interior

While the prototypes spied here are comprehensively disguised, the new SUV remains close to the existing model in size with a length of around 4700mm, a width of 1950mm and a height of 1650mm.

A moderate increase in the wheelbase, which currently stretches to 2810mm, promises to provide added levels of accommodation, most notably in the rear, where officials suggest the model benefits from additional leg and shoulder room. Boot capacity is also said to have increased beyond the nominal 540 litres of today’s Q5.

Audi design boss Marc Lichte has given the Q5 a more rugged look than that of the recently introduced Q7. Seen here, elements such as prominent wheel arch flares and large wheelhouses are evident underneath the camouflage of these latest test mules. Like the original model, it also appears to feature a clamshell-style one-piece tailgate with integrated tail-lights.

As with the new A4, buyers will get to choose between standard bi-Xenon headlights, with LED and LED-based Matrix units set to be made available as an option, according to highly placed Ingolstadt insiders.

Inside, there is a highly contemporary dashboard similar in look to that first unveiled on the third-generation Audi TT and continued with mild changes on the latest Q7 and, most recently, the new A4.

Buyers will get to choose between three different control systems: the standard and base MMI arrangements operate in combination with a 7.0in free-standing monitor and rotary dial, while the top-of-the-line MMI Plus system combines with a larger 8.3in monitor, rotary dial and touch pad.

As with the A4, the Q5 will also feature up to two separate Nvidia Tegra 30 chipsets – one for the free-standing monitor and the other for an optional active instrument display, each capable of supporting the latest Google Earth 7.0-based navigation in combination with MMI Plus. Audi is also working closely with driver assistance system specialist Mobile Eye to provide the Q5 with the latest in 3D camera technology for a variety of driver aids.

The new Q5 will be sold with a range of four-cylinder and V6 petrol and diesel engines from the outset. In combination with efforts that are claimed to have reduced aerodynamic drag to less than 0.30 and brought about a significant lowering in mechanical drag, they are said to provide fuel economy savings of up to 15% compared with the first-generation model.

The four-cylinder petrol and diesel engines and standard V6 diesel units are set to be carried over from the latest A4 without significant changes, while the V6 petrol engines form part of a new generation of powerplants being developed in a joint engineering project between Audi and Porsche under the codename KoVoMo.

Also planned is a new plug-in hybrid driveline option. It uses a 2.0-litre four-cylinder petrol engine in combination with two electric motors, with one mounted within the gearbox and the other within the rear axle. Already highlighted on the Audi Allroad Shooting Brake concept revealed at the 2014 Detroit motor show, the new system is said to provide the new Q5 with an electric range of up to 31 miles.

Moves are also afoot to provide the Q5 with a wider range of performance engine options. The 3.0-litre V6 diesel engine used in the existing SQ5 is rumoured to receive a moderate increase in output, taking it from 306bhp to around 325bhp. Also planned is a twin-turbocharged 3.0-litre V6-powered range-topping RS Q5 model developing in the region of 500bhp.
