Audi?s Bi-turbo V6 Diesel puts out a very impressive 313bhp and 479 lbs/ft or torque. Tunit increased power to 353bhp and torque jumped up to 533 lbs/ft. The overall drivability of the car benefits from increasing torque, making throttle response and acceleration smoother and more immediate. More power in lower revs also means that the 8 speed automatic gearbox can change up at 1000 revs rather than 1100 or higher, bringing better economy.
Economy is the one area that hinders most 4 wheel drive SUV?s and for the Audi, it is the one are that rival BMW X3 35d does better in. The official economy figure according to Audi is 39mpg. Tunit also gives an average 12% increase in fuel efficiency. Having extra torque when setting off or to get up to speed when traveling long distances means Tunit puts the SQ5 back into the lead.
