The Electric Porsche Cayenne Just Torched The V8-Powered Audi RS Q8
The RS Q8 is a 631-horsepower super SUV but it stood no chance against Porsche's electrified SUV.
The Audi RS Q8 is no slouch. It's basically a Lamborghini Urus Performante in a classier business suit. Its 4.0-liter twin-turbocharged V8 makes 631 horsepower and 627 lb-ft of torque. It hits 60 mph in about three seconds and has a top speed of 190 mph. Those are supercar numbers in a five-seat SUV. And yet, despite the RS Q8's impressive credentials, it gets absolutely smoked by the new Porsche Cayenne Electric.
In this new video from Autotrader UK, Rory Reid puts both mega SUVs to the test to see which is better, but not just in a straight line. He also tests their ride quality, range, practicality, and track performance. And, spoiler alert: the electric Porsche dominated.
Through the quarter-mile, the go-fast Audi took 11.6 seconds, a highly respectable time for any SUV, and it crossed the line at 162 mph. The Porsche, though, did it in 10 seconds flat, at 170 mph. That's just nutty for an SUV.

To test their ride comforts objectively, Reid took both cars on a series of rumble strips and used a seismometer app to determine how well they could handle it. In both of their most comfortable settings, the Porsche won yet again, netting itself two wins to zero.
On track, you might think the Audi would have an advantage. It's a hefty thing, at just over 5,300 pounds. But the Porsche weighs as much as medium-sized meteor, at over 5,900 pounds. So even though the Cayenne makes almost double the power, at 1,139 horsepower, you might think its extra 600-ish pounds would hurt it through corners. But nope. The Porsche was almost five seconds faster through the road circuit. So it's faster in a straight line, it's faster around a track, and it's even more comfortable. It's also considerably more expensive, so it had better be better, but it's shocking to see just how much faster and more capable it is.
EVs being quicker than gas performance cars isn't news. It's easier to make big power from electric motors, and they deliver that added power instantly. So it's no surprise that an EV performance SUV is faster than a gas one. But to see the RS Q8, one of the fastest SUVs on the planet, get its ass absolutely handed to it in almost every measurable way is quite the surprise.
