In this day and age when downsizing seems to be the norm in the automotive industry, a V8 diesel seems like a dinosaur. Nevertheless, it’s what the Volkswagen Group chose for the European Audi SQ8 as well as for the Volkswagen Touareg and Bentley Bentayga. A new video courtesy of 1001cars / YouTube shows the SQ8 TDI putting its electrified twin-turbo 4.0-liter engine at work for an acceleration test.
Before we even begin to look at the juicy performance numbers, let’s take a moment to appreciate the soundtrack delivered by the engine. You can hardly tell it’s a diesel, but it is worth mentioning Audi installs a sound actuator in the exhaust system, allowing the driver to modify the soundtrack via the drive select system.
The SQ8 TDI demonstrated its sports car-like capabilities in the acceleration test, needing just 4.75 seconds to hit 62 mph (100 km/h) from a standstill. That’s actually slightly better than the time provided by Audi, which isn’t all that surprising since the German luxury brands are known to understate the performances of their cars.
The test didn’t stop there as the driver continued to push the SQ8 TDI, reaching 124 mph (200 km/h) in 18.4 seconds. The impressive time was possible not only because of the immense power delivered by the big diesel, but also thanks to the quick launch control system, Quattro all-wheel drive, and the eight-speed tiptronic transmission.
Putting the full 435 horsepower and 664 pound-feet (900 Newton-meters) to work, the SQ8 TDI eventually got up to 160 mph (258 km/h) as per the onboard GPS. Later on, the large diesel SUV is put through its paces to show how fast the automatic gearbox reacts when kickdown is triggered under hard acceleration.
At the end of the video, there are a couple of charts showing all the performance numbers and how these stack up against other large luxury SUV, some with diesel engines and others running on gasoline. As you can see, the SQ8 TDI came out on top.
