The new Audi RS6 Avant is powered by a twin-turbocharged, 4.0-liter, V-8 engine that delivers a total of 560 horsepower, making it one of the most powerful sports wagons out there. Even the best can be better sometime, so the German tuner O.CT Tuning found a solution to improve this output even further.
The tuner is offering two stages of upgrades for the RS6 . In Stage 1, the engine electronics are heavily modified, pushing the V-8 engine to a blistering 670 horsepower and a peak torque of 649 pound-feet.
With the extra 110 horsepower under the hood, the RS6 awakens to a tune of 0 to 60 in 3.4 second. Top speed is increased to 190 mph, but an optional set of tires allow O.CT to unharness the RS6 to a top speed of 200 mph.
A Stage 2 upgrade is also available, and it includes an additional sports exhaust system that adds another 10 horsepower to the output level delivered by stage 1.

Audi RS6 by OCT Tuning in Detail
The Audi RS6 Avant is already a sick-looking rig, so O.CT Tuning opted to keep all of its focus on pumping the most power from the V-8 powerplant. Still, that black exterior paint draped on this wagon is simply sinister.
Audi unveiled the new RS6 Avant in 2012, and it may be the best A6 ever. It is about 220 pounds lighter than its predecessor, more powerful, faster, and of course, better looking.
The new RS6 Avant is powered by a twin-turbocharged, 4.0-liter, V-8 engine that delivers a total of 560 horsepower between 5,700 and 6,700 rpm, and 516.29 pound-feet of torque between 1,750 and 5,500 rpm. This output is enough to sprint the car from 0 to 60 mph in 3.9 seconds and up to an electronically limited top speed of 155 mph. An optional Dynamic Plus package will increase top speed to 189 mph.
The RS6 Avant is priced from £77,000 - about $124,000 at the current exchange rates.

What will happen, if you transplant the 4 liters Audi A8 engine into the car
body of its smaller brother A6 and improve the interior of the latter in the
same time? The result of this surgical effort is called by the well sounding
name Audi RS6 Avant 4.0 TFSI quattro „NEW“. Is it all? The answer to even
this question is researched by the O.CT Team. You better believe it! Once
more, a mega stunner comes from the development department of the
Oberscheider Tuning GmbH Lustenau, Austria.
The specified target is totally clear. In particular, the performance
optimization by modification of the engine electronics is to be perfectly
coordinated with the engine characteristics. If the “normal” values of the
Audi RS6 with 560 HP / 412 kW and 700 Nm of torque are not bad at all, the
reprogramming of the engine controller will give imposing 670 HP / 493 kW
with 880 Nm of torque. While the acceleration from stand to 60 mph with
serial power does not exceed 3.9 seconds, after the “intervention” fabulous
3.4 s order of the day. By the way, Vmax can be improved in different ways,
whereby 300 kmph (190 mph) is standard improvement. Optionally, 320 kmph
(200 mph) or more is possible, demanding, however, special tires.
It is understood that O.CT emphasizes the fact that all kind of offered by
this company performance optimizations are exclusively exactly verified own
developments. To fulfill highest demands and to deliver best quality is for
O.CT in the same way matter of course, like its top motivated team with many
years of experience and an all-wheels performance test station with recent
electronic and computing equipment and high-tech data gathering system,
leaving nothing to be desired. Thus, moreover, the coordination of all
involved into the performance optimization particular devices is made
perfect. In the result stands pure driving fun with undreamed-of driving
dynamics, without influencing the vehicle’s longevity.
There is still to be mentioned that O.CT offers already metamorphose stage 2
with additional sports exhausting system (Hammer V8 Sound by touch of
button). In this case, the engine power increases slightly up to 680 HP/880
Nm. Thus, probably, the Audi RS6 4.0 TFSI quattro by O.CT nearly demands a
