What will happen, if you transplant the 4-liter Audi A8 engine into the engine bay of its smaller brother the A6 and while you are at it, take time to upgrade the interior of the A6? The result of this surgical effort is called by the well sounding name Audi RS6 Avant 4.0 TFSI quattro? The answer comes from the O.CT Tuning house.
If the “normal” values of the Audi RS6 with 560HP and 700 Nm of torque are not bad at all, the reprogramming of the engine controller will give this tuned A6 some 670HP with 880Nm of torque. While the acceleration from standstill to 100km/h gets improved to a supercar 3.4 seconds and top speed pushed further up the speedometer range to 320km/h where permitting.
