If you were to show pictures of the Lamborghini Aventador SVJ and Porsche 911 GT2 RS to someone who doesn’t know much about cars and asked them which of the two accelerates the fastest, most would guess the Lamborghini. But is it actually quicker than its German rival?

To find out, Formula E driver Daniel Abt brought the two along to a runway for a series of drag races, both from a standstill and from a roll. The results may surprise you.

Powering the Aventador SVJ is a 6.5-liter naturally-aspirated V12 pumping out 759 hp and 530 lb-ft (718 Nm) of torque while the Porsche delivers 690 hp from its twin-turbocharged 3.8-liter six-cylinder. However, the Porsche has a torque advantage with 553 lb-ft (750 Nm) and is also rear-wheel drive, meaning it has less drivetrain loss than the Aventador. It also weighs less than the Lamborghini.

In the first race from a standing start, the drive of the SVJ nails the launch and accelerates into a quick lead while Abt, behind the wheel of the 911 GT2 RS, struggles to put the power to the ground without spinning up the rear wheels. In fact, it took 3.8 seconds for the Porsche to reach 62 mph (100 km/h).

In the second race, Abt got a much better launch and was able to get off the line better than the Lamborghini, despite only having rear-wheel drive. As the speeds started to build, the Porsche continued to stretch out its lead, easily defeating the Lamborghini.
