Audi has confirmed its first ’S’ variant of the Q7 SUV will cost upwards of £70k OTR. With the German brand claiming it’s the most powerful diesel SUV on the market, it seemed only right to put the SQ7 TDI’s 900 Nm of torque to work.. against a fighter jet. With 435 PS, 0-62 is dispatched in 4.9 seconds thanks in no small part to Audi’s new electrically driven turbochargers. Powered by compressor technology rather than exhaust flow, the new system effectively consigns conventional ‘turbo lag’ to history. The Audi SQ7 TDI is on sale now.
