The Audi RS6 Avant is one of the easiest cars on the market with which to make epic power. Its 4.0 liter twin-turbo V8 might not be the most potent of its kind in its class — only making 591 horsepower from the factory (it’s crazy that’s the least amount of power in the class) versus the 600-plus from BMW and AMG — its tuning potential is immense. Hennessey, the Texas-based tuner famous for insane power figures, recently built an Audi RS6 Avant with 800 horsepower and used it to set a world record for hauling a Christmas tree.
Hennessey was actually testing its bespoke hypercar, the Venom F5, and working toward a potential 300 mph top speed (!) when it decided to have some festive Christmas fun. The Audi RS6 Avant in question actually belongs to John Hennessey’s wife, so they decided to strap a Douglas Fir to the roof of it and see how fast it could go. Hennessey actually did this once before, with a 1,000 horsepower Jeep Grand Cherokee Trackhawk and reached 181 mph with the tree on the roof.
However, the Audi RS6 Avant with just 800 horsepower was able to reach 183 mph with the Christmas tree on the roof. That’s seriously impressive because the tree not only adds weight but it also adds a ton of aerodynamic drag. You might not thing the tree makes a big difference but the same RS6, on the same runway, with the same driver, reached 205 mph without the tree. So it makes a big difference.
At 183 mph, the Audi RS6 Avant is the fastest Hennessey vehicle down the strip with a Christmas tree. So if you’re looking to haul your family’s tree back home in record time, you now know which car to get. If only Clark Griswald had an RS6 Avant, he’d have had an easier Christmas Eve.
