Audi have decided the RS6 Avant and RS 7 Sportback haven’t yet been fully corrupted by power and therefore have given the two performance stars more power in the hope of absolute corruption. However the absolute power from the 4.0 twin-turbo V8 TFSi has been increased by slightly by 45bhp to 605bhp and 700Nm of torque. An ‘overbost’ function increases torque to 750Nm. The eight-speed dual-clutch transmission has been revised which allows both of these performance cars to snap from 0 to 62mph in just 3.7 seconds, an improvement of 0.2 seconds over the respective standard RS model. The top speed is electronically limited to 155mph however this can be increased as an option to 174mph, or 189mph if you go for the dynamic package plus option. Both models get Audi’s permanent Quattro all-wheel drive which is programmed to distribute torque as needed via the centre differential. In the standard configuration, 40 per cent flows to the front axle and 60 per cent to the rear. A sport differential acting on the rear axle is also standard, and enables active torque distribution between the inside and outside wheel. That means you can corner at lunatic speeds, that is if you are indeed a lunatic. Both the RS 6 and RS 7 will offer the very best of refinement and a new name to distinguish what are in effect minor upgrades. These upgrades also include 21-inch aluminum wheels and carbon-fibre ceramic disks, but as options. You can order either the RS 6 Performance or RS 7 Performance from November onwards priced respectively at £86,000 OTR and £91,600 OTR. First deliveries are expected in February 2016
