Aston Martin DBX 707 vs Porsche Cayenne Turbo GT: verdict

These two musclebound monsters sit at the very top of the sports SUV tree, but which is the king of the jungle?...

New Aston Martin DBX 707 vs New Porsche Cayenne Turbo GT rear cornering

Our verdict

The Porsche Cayenne Turbo GT sets a new benchmark for handling among sports SUVs. Its grip, balance and poise have to be experienced to be believed and could give unsuspecting supercar drivers a fright on track days. It’s also outrageously fast in a straight line, reasonably practical and, in this company, quite reasonably priced.

However, those looking for the ultimate super-SUV experience should plump for the Aston Martin DBX 707. Not only does its bombastic engine note add an extra dimension of theatre to its face-melting acceleration, but it’s also comfier, quieter, more spacious, better equipped and more interesting inside. We’d go so far as to say it’s the best Aston Martin we’ve ever driven.
