As far as performance SUVs go, the Audi SQ7 TDI is one of the better ones on the market. It also has the distinction of being one of the only diesels. Packing a triple-turbocharged 4.0 liter V8 TDI engine, the SQ7 is mighty quick. It makes a simply monstrous 435 hp and 664 lb-ft of torque, which helps it get from 0-60 mph in a claimed 4.8 seconds (more on that later). But it isn’t the only performance luxury SUV on the market. Another is the Tesla Model X and, in 100D spec, it’s very, very fast. So which can accelerate and brake the fastest? Carwow finds out.
With its 100-kWh battery and dual electric motors, the Tesla Model X 100D can supposedly nail 0-60 mph in 4.2 seconds, according to Tesla’s site. So that’s a bit quicker than the Audi SQ7’s claimed time. However, as you’ll see in this video, both cars are a bit off their claims. The first test of these two cars is a standing quarter-mile drag race. It’s the Model X that takes the win, doing the quarter-mile in 13.4 seconds, compared to the Audi’s 13.5 seconds. Oddly enough, the Audi SQ7 was actually going faster when it crossed the line, doing 106 mph to the Tesla’s 102 mph. That’s mostly because electric cars run out of puff at around 100 mph, while the SQ7 can keep pulling strong.
Now, as far as acceleration numbers go, both companies were a bit off on their claimed times. The Tesla Model X really took 4.9 seconds to get from 0-60 mph, rather than its claimed 4.2 seconds. The Audi SQ7 took 5.1 seconds, rather than its claimed 4.9 seconds. So the Tesla was still quicker that the Audi, just slower than Tesla says. The Tesla, thanks to its electric torque, also accelerates more violently. With a crew member in the third row of each car, holding a cup of water, they tested the ferocity of each car’s power. In the Tesla, the crew member spilled more water on acceleration than in the Audi.
The real surprising part was in the braking test. The Audi SQ7 TDI has much bigger brakes, with three-piston calipers up front and two-pots at the back, it’s lighter and has more aggressive tires. So you’d think it’d destroy the Tesla, in terms of braking. However, the Model X actually finished braking from 70-0 mph in about 10 feet less than the SQ7. That’s really impressive.
Carwow didn’t get into handling, dynamics, ride comfort or luxury in this video, but as far as just pure acceleration and braking go, the Tesla Model X is the faster car. It’s still awful looking, though.
