Audi unveiled the SQ5 TDI as its R18 sports prototypes dominated the Le Mans 24 Hour Race in France.

The new super-SUV is the first TDI-powered "S" model in the history of the Vorsprung durch Technik brand.

The 3.0-litre BiTDI engine powering the SQ5 TDI produces a 230kW and 650Nm of torque between 1450 and 2800rpm. Channelled through an eight-speed tiptronic automatic transmission and via quattro all-wheel-drive it is good for a 0-100km/h time of 5.1 seconds. A specially developed sound actuator in the exhaust system has been included to enriches the exhaust note and give it a sportier sound.

Sport suspension lowers the body by 30 millimetres. The standard 20-inch wheels, which at the front frame black brake callipers with "S" badging,  feature a five parallel-spoke design and are fitted with 255/45 tyres. Optional wheels measuring 21 inches in diameter are also available. The optional Audi drive select system can be expanded upon request to include the dynamic steering system with its steplessly variable steering ratio.

The most eye-catching design cues distinguishing the new SQ5 TDI are the platinum grey single-frame grille with its galvanised double bars in an aluminium-look finish, the roof spoiler and the modified bumpers. The high-gloss package and the aluminium-look exterior mirrors accentuate the area around the windows. Audi offers the new top model in the crystal effect paint finishes Estoril Blue or Panther Black. The body includes a high proportion of ultra-high-strength steels, making it very light, safe and rigid.

As is typical for an S model, the interior is finished predominantly in black, but the headlining is optionally available in lunar silver. The power-adjustable sport seats are leather-upholstered as standard, complementing brushed aluminium inlays. Inlay options include Carbon Atlas, Piano finish and the new Aluminum/Beaufort wood black trim panels.

The instrument dials are grey and include a 3D-design S badge, the needles are white and the pedals and shift paddles have an aluminium-look finish. Additional visual highlights in the interior are the S gear lever knob, the S badges on the door sill trims, the start button, the specially-shaped steering wheel and the lighting package.

Luggage capacity is as much as 1560 litres.
