Head-to-head on the roads in what could be the best two megasports saloons you can buy
What are the ideal ingredients for a brilliant 2018 sports saloon? A thundering twin-turbocharged V8 making pots of power? Four-wheel drive, but with the option of switching off the fronts for a little extra fun? Enough doors, interior space and luxury to allow you to share a stonking experience with three others?
That’s what both BMW and Mercedes-Benz reckon makes a super saloon, sports sedan or whatever else you care to call it, because both the M5 and the E63 S deliver exactly that package.
The 4-litre twin-turbo V8 Mercedes has 603bhp and 627lb ft of torque. It weighs 45kg short of two tonnes, does the 0-62mph run in 3.5 seconds and goes on to 186mph.
The 4.4-litre twin-turbo V8 BMW has 591bhp and 553lb ft of torque, but weighs 100kg less than the Merc so is even quicker – slightly – through the 0-62 at 3.4sec. Its top speed is limited to 155mph.

Now it’s your turn to decide between these two cars. The good news is that it’s a no-lose situation. They’re both amazing.
