A guide to power units and safety systems on the Audi Q3

The Audi Q3 has a range of four engines available all combining direct fuel injection with turbo charging and all backed up by start-stop and energy recuperation systems - the 2.0-litre TFSI petrol unit in 170PS and 211PS forms and the 2.0-litre TDI with 140PS and 177PS.

The 2.0-litre TDI 140PS unit powers the front-wheel-drive model only.

The 2.0 TDI 140PS and 2.0 TFSI 170PS engines are linked to a six-speed manual transmission as standard, while the 2.0 TDI 177PS and 2.0 TFSI 211PS units feature a development of the seven-speed S tronic transmission.

The Audi drive select adaptive dynamics system is available as an option to enable drivers to tailor the Q3’s driving characteristics.

The system incorporates comfort, auto, dynamic and efficiency modes which influence the responses of the throttle and steering, and also the optional adaptive light and cruise control systems where these are fitted.

When the efficiency mode is selected, the electronic climate control and cruise control systems operate at the optimum level for minimal fuel consumption, and in models with S tronic transmission, the active clutch is disengaged each time the driver lifts off the throttle, allowing the Q3 to use the momentum already built up to ‘coast’ without the need for engine input.

The Q3 has a wide range of safety systems, adopted from executive and luxury class Audi models, designed to help to prevent collisions and to make it easier for drivers to keep in lane on the motorway, to change lanes, draw attention to important traffic signs and assist with parking.

The Audi side assist system activates at speeds above 19mph to help drivers change lanes on motorways and dual carriageways.

Two 24-gigahertz radar sensors in the rear observe what is happening behind the Q3 to a distance of 70 metres. If another vehicle is in the critical zone – if it is travelling in the blind spot or approaching rapidly – the so-called information stage is activated. A yellow LED indicator illuminates in the casing of the driver's side mirror; the driver sees it only when looking directly into the mirror. If the driver then activates the indicator to change lanes, the indicator becomes brighter and pulsates.
