The new BMW M5 is a terrific sports saloon. Or super saloon. Or sports sedan. Call it what you will: it's a big four-door executive car with a stonky twin-turbocharged V8 making shed loads of power, which it puts it through all four wheels - unless you stick it in rear-drive mode, in which case it only puts it through the rear wheels, obvs. Subscribe now:

And if that sounds familiar, that's because it's exactly what the Mercedes-AMG E63 saloon does too: what with its four-door body, luxurious executive car interior, twin-turbocharged V8 engine and four-wheel drive with the option of rear ... well, you get the idea.

But which of these big saloons is best? Both as an everyday executive car, but also as an enjoyable car to drive. Step forward Autocar's two video-ready testers, as we find out which you should have: BMW M5 or Mercedes-AMG E63 S.

      Dragy's all time fastest 0-60 runs lists 35 verified runs under 2.0 secs. 18 of those 35 records are held by Nissan GT-Rs. 0 are Mercedes. Dragy proves, irrefutably, that there is only one supercar in the world today, and nothing else can touch it. Nissan towers over all other makes, they utterly dominate every speed category and no other manufacturer even registers. Thats the hard data, everything else amounts to pussies whining about losing.

      It's a matter of taste, I drove different BMWs and different Benz's. Both has good interiors, Benz is probably more reliable, bot exterior looks are beautiful. With all that I find BMWs more exciting. And less pricy 😜

      I'd be happy behind the wheel of any of these cars, really. I don't know why BMW and MB fanboys keep bickering about.

      M5 is and will always be the benchmark in this segment and so is M3. Merc S Class is a benchmark to the rest

      Car reviewers need to stop describing vehicles as "special" because it's meaningless.
