Audi SA has said it is considering adding the hot SQ5 TDI bi-turbo diewel to its local line-up. It was billed as an “exclusive concept” at the 2012 Paris auto show but that was never going to last long… The biturbo SQ5 is now available to order in certain markets and Audi SA said: "It’s being investigated for local introduction pending diesel fuel quality testing."SPORTY SUVThis the first diesel 'S' in the Audi range has a three-litre V6 BiTDI engine that delivers 230kW from 2900-4500rpm and 650Nm from 1450-2800rpm. Its power is transmitted to all four wheels through an eight-speed auto transmission. It runs 30mm lower than the standard Q5 on an S sports suspension while 20” five-spoked alloys fill the wheel arches. Audi’s Drive Select system, which offers a choice of Comfort, Auto, Dynamic and Efficiency modes, influences the weighting of the steering, transmission shift points, throttle response and suspension settings. Typical of an “S” model, interior finishes are mostly black with aluminium accents.Standard equipment includes a 180W Audi sound system, a 17cm colour monitor, Bluetooth, cruise control, three-zone climate control, light and rain sensors and rear parking radar. Audi, when the car was shown in Paris, said it would produce the SQ5 TDI in a limited production run of only 50 vehicles.
