We’ve already seen Hennessey Performance dyno test their latest creation tuned before, the Lamborghini Urus. Note that on paper, the Urus produces 641 horsepower (478 kilowatts) and 627 pound-feet (850 Newton-meters) of torque.
On the test bench, however, the Audi-derived 4.0-liter twin-turbo V8 of the Urus develops 546 hp (407 kW) and 606 lb-ft (822 Nm) of wheel traction. The Texas tuner applied their HPE750 performance upgrade to the super SUV, which increased the power output to 620 hp (462 kW) and 730 lb-ft (990 Nm) of torque transmitted to all four wheels. These represent a 74 horsepower and 124 lb-ft of update.
To showcase this performance, Hennessey pits the HPE750 against a production vehicle – a Rolls-Royce Wraith. Yes, we know, an SUV tuned to a production luxury vehicle drag race looks like a mismatch, but remember the Wraith and Urus are on the same ground on paper.
With a twin-turbo V12 under its hood, the Wraith puts out 623 horsepower (465 kW) and 642 lb-ft (870 Nm) of torque, at least in its Black Badge iteration. The stock Urus is already a plus, but wait until you see it run the luxury coupe with the updated HPE750.
As mentioned in the caption above, the outcome of this drag race was not at all surprising, with the power advantage and all-wheel drive telling us that the Italian SUV won this race. But how far was the gap between the two? You can watch the video at the top of this page.
The HPE750 upgrade for the Urus is now available from Hennessey for $ 24,950 plus vehicle shipping. You can also choose to apply the upgrade to an Audi RS Q8. Just give Hennessey four weeks to build your super SUV.
