Audi has announced plans to offer a new, powerful diesel version within its successful Q5 model lineup. Alongside the Audi Q5 3.0 TDI, the new Audi SQ5 TDI becomes the first S-Line model powered by a diesel engine. The SQ5 TDI will also be the first S-Line model in the entire Q-series.

With the announcement of the Audi SQ5 TDI, Audi is following its toughest competitor in the premium segment, BMW, which unveiled three diesel-powered BMW M performance automobiles in the beginning of the year.

The Audi SQ5 TDI will be powered by a 3.0-liter diesel engine developing 313 hp (230 kW) and having a massive 479 pound-feet (650 Nm) of torque, available between 1,450 and 2,800 rpm. To generate this power, Audi uses a twin-turbo design and has modified several other engine components, including the cylinder head- and oil-jet cooling and the intake camshafts.

The modifications also include an increase of the injection pressure of the Bosch common rail system to 2,000 bar (29,007 psi) and an eight-speed tiptronic automatic transmission (by means of comparison, the Audi Q5 3.0 TDI is equipped with a seven-speed S tronic automatic transmission and has an injection pressure of 1,800 bar (26,107 psi).

To deliver all of this power onto the road, the Audi SQ5 TDI is of course fitted with Audi´s proven quattro all-wheel drive system.

The Audi SQ5 TDI accelerates from 0 – 100 km/h (0 – 62 mph) in 5.1 seconds and offers a top speed of 250 km/h (155 mph). According to Audi, the average fuel consumption is 7.2 l/100 km (32.67 mpg).

In an interview with The Diesel Driver, Audi confirmed plans to introduce several diesel-powered models for 2013. These include the Audi A8 TDI, A6 TDI and the Q5 TDI. Audi has not yet indicated if the SQ5 TDI will also make it to the U.S. but European customers will be able to start ordering the Audi SQ5 TDI in the first quarter of 2013, with prices starting at €58,500.
