The two are base on the same VW Group platform, which the chassis being put together at the same factory. In terms of luxury, the Bentayga is a cut above the rest, but that also makes it quite heavy. We also want to point out that it costs four times more than the Alfa Stelvio Quadrifoglio, which in any other company would seem like an incredibly fast vehicle.
The 608 PS, 900 Nm W12 engine makes the Porsche seem like it's not trying hard enough since it only makes 550 HP and 770 Nm of torque. And in the drag, we see pretty much what everybody expected. The slightly lighter Porsche gets a better launch and gets to 60mph quicker, maintains its lead to 100mph and passes the quarter-mile mark in 11.8 seconds.
The Afla Stelvio performs admirably, edging just ahead of the W12 by the quarter-mile marker. But because of its lower top speed, it can't keep up with the big boys over the half-mile. Still, you can buy both the Italian SUV and the Porsche and something left over with the money spent on that Bentley behemoth. So is it worth it? If you're looking at it that way, then you're probably not one of the few thousands of people who can afford to buy one every year.
