Bentley Bentayga shocks the world – and rightly so
Ladies and gentlemen, the world’s fastest diesel SUV is…the Bentley Bentayga.
Yes, you read that right – the company that only recently started making SUVs currently makes the world’s fastest diesel SUV.
Back in 2015, Bentley shocked the car world with a major announcement.
The company known for making low-volume, bespoke luxury grand tourers was entering the SUV game.
It was an announcement that was met with a mixture of groaning and ridicule.
Why would a legendary luxury brand such as Bentley try to stick its nose in the SUV market?
But Bentley proved to be deadly serious about its SUV ambitions.
Sharing a basic platform with the Audi Q7, the Bentley Bentayga shocked and wowed in equal measure.
But what shocked and wowed the masses even more was the powerplant that dwells within the engine bay.
Powering this luxury beast is a powerplant that is a true, bespoke work of art.
It just so happens to be a 4.0-liter V8 diesel – and it comes with some serious firepower.
Sequential turbochargers and a supercharger provide some incredible kick to this engine.
It all adds up to 429hp and a whopping 664lb-ft of torque.
Back in 2018, the world’s fastest diesel SUV put up some truly staggering numbers.
It managed to hit a 0-60 time of just 4.2 seconds, and completed the quarter mile in just 12.6 seconds.
World’s fastest diesel SUV vs Ford Mustang Dark Horse?
So how would the world’s fastest diesel SUV perform against a Ford Mustang Dark Horse?
Well, a quarter-mile drag race would be far closer than it probably should be.
The 500hp V8 powers the Ford Mustang Dark Horse to a 0-60 time of just 4.1 seconds.
It will also complete the quarter-mile in 12.5 seconds – literally a touch faster than the Bentayga.
But there is a point where the world’s fastest diesel SUV will actually overtake the Ford Mustang Dark Horse.
The Bentley Bentayga will complete zero to 100mph in just 9.5 seconds.
That is two-tenths quicker than the 9.7 seconds of the Ford Mustang Dark Horse.
The world’s fastest diesel SUV also has a slightly higher top speed, if you can believe that.
It turns out that the Bentley Bentayga has a top speed of 168mph.
The Ford Mustang Dark Horse, on the other hand, has a top speed of 166mph.
Of course, the Dark Horse is much, much lighter than its Bentley rival, and that would be the difference.
But nobody can argue that a Bentley Bentayga should be capable of that level of performance.
The world’s fastest diesel SUV is certainly not to be disrespected.
