This still leaves a comfortable margin between the 2011 BMW 740i and the 750i, which hits 60 mph in 5.2 seconds and the quarter-mile in 13.5 at 103.7 mph.
But the 740i leaves V8 sedans like the Hyundai Equus and Lexus LS 460 for dead. It’s also a bit quicker than the 2011 BMW 535i (with the single, twin-scroll turbo N55 engine), even though the latter weighs 300 pounds less.
Porsche is the only other manufacturer with the gall to put a straight-up gasoline six-cylinder in a large high-end sedan (Mercedes-Benz has been discreetly slipping V6s into hybrid and diesel versions of the S-Class), and the 740i matches the performance of the lighter but less powerful Panamera V6
