As more and more people are getting their hands on the new Audi RS6 Avant, aftermarket specialists are eager to see the tuning potential of the twin-turbo 4.0-liter engine. UK-based Durham Remaps has managed to get a hold of the super wagon and tweaked its Electronic Control Unit (ECU) in an attempt to squeeze more power. Following a dyno run, the V8 generated some impressive output numbers.
With only a stage 1 remap, the engine pumped out 728 horsepower at 5,540 rpm and a whopping 1,052 Newton-meters (776 pound-feet) of torque at 3,836 rpm during the dyno test. There’s more to the ECU remap than just massaging the engine for extra power as Durham Remaps says fuel consumption is down by as much as 8%, so it’s a win-win situation.
As great as these numbers are following the ECU remap, we’re more impressed by the stock output of the engine – 633 hp and 840 Nm (620 lb-ft). As you may recall, Audi rates the V8 at “only” 600 hp and 800 Nm (590 lb-ft), but it turns out it’s actually got more oomph than advertised.
It’s not that big of a surprise since the three German luxury brands have the tendency to deliberately understate the output figures of their engines. With the right mods, there’s a pretty good chance the new RS6 Avant will eventually reach the four-digit horsepower figure. Come to think of it, German tuner Wheelsandmore has already bumped the V8 to 996 hp, and the car hasn’t even been out for that long.
Whatever the tuners can do to the RS6 Avant’s engine they should be able to do with the twin-turbo 4.0-liter V8 installed in the RS7 Sportback and the RS Q8 since these three cars share essentially the same powertrain.
Power numbers aside, the attached video gives us one of the first opportunities to see the new RS6 Avant on a dyno looking mighty fine in the Nardo Gray paint scheme. This particular car is a right-hand-drive example with the optional ceramic brakes as denoted by the red calipers and it sits on the 22-inch alloy wheels that also cost extra.
