Adiesel Bentley. I'm cursing the idea right now, but not due to misplaced nostalgia. Nope. The Bentayga diesel has inspired the boss back at TG Towers to lay me down a seemingly impossible task: driving one back home from the Marbella press launch on just two tanks of fuel. That's 1,400 miles, if you're wondering. The theory is sound. Bentley knows that its owners don't require 35mpg economy, but that there is luxury in making as few monotonous fuel stops as possible. The reality, though, is that I'll need to squeeze 700 miles from a tank of fuel, when Bentley's claimed range is 621. Impressive for a 2.5-tonne, 429bhp V8-engined SUV, but not enough.
