The Bentayga is a bit of a departure from Bentley's usual offerings. However, that doesn't make it a bad car. In fact, this exquisitely-trimmed, 186 mph Bentley SUV can do seemingly anything you'd ever need a Bentley to do. Vast power from a twin-turbo W12 and electronic anti-roll bars that constantly adjust to suit driving needs mean this is a serious piece of kit.
BMW X5 M
The X5 M is the M5 for a big family. For those who want proper M-division performance combined with a high level of practicality, this is the go-to. Sure, the X6 M is essentially the same car with a sleeker roof line. However, the X5 M is the real SUV of the range. It combines a huge trunk and a quality interior with a meaty, twin-turbocharged V8 to produce a very well-rounded package.
Porsche Cayenne Turbo
Porsche's Cayenne Turbo has been a hit throughout its first two generations, despite its controversial styling. The new third-gen Cayenne Turbo continues to hone the recipe that has worked so well in recent years. The massive, luxurious SUV gets nearly 600 horsepower from its twin-turbo V8, which is plenty if you're ever running really late to a family get-together.
As I focused on the BMW X5 rather than X6, I'll be focusing on the full-size GLE here rather than its sibling, the GLE Coupe. This car is Mercedes' answer to BMW's X5, and is suitably large and filled with all the technology and leather you'd expect. The AMG model gets a hand-crafted bi-turbo V8 good for over 570 horsepower and one glorious engine note.
Tesla Model X P100D
While the Tesla is the only car on this list without a relatively large, turbocharged engine, it's actually the most powerful car on this list. That's right, the completely electric drivetrain in this car is taken straight from the stupidly-quick Model S. This means the Model X is capable of a whopping 762 horsepower in P100D guise. These upgraded batteries allow for huge acceleration and far more torque than your family will ever be ready for. It's also got gullwing doors. Name another fast SUV with gullwing doors.
