Top Gear decided to take on the Herculean task of harnessing two AWD monsters for a 1,500-mile trip to establish which is better: the all-new BMW M5 or the Mercedes-AMG E63S.   They claim the war between BMW M and AMG has raged for long lengths of history, so they hope to settle it once and for all with these two highly-powerful, highly-coveted models.

Both have the all-wheel-drive systems that allow them to be functional daily drivers in all sorts of inclement weather while also having a rear-wheel-drive mode to allow for some thrilling drift sessions when the rain is coming down and the kids are in the back.  The 7th generation M5 arrives with a 4.4-liter twin-turbo V8 with 600HP and 553lbs-ft of torque.  0-60 times are at an astonishing 3.2 seconds, while climbing to 124MPH arrives in 11.1 seconds (but don’t do that on a public road, please).  Even with the addition of the all-wheel-drive system, the all-new BMW M5 is actually lighter than the last generation.

For Car and Driver, when they took the first BMW M5 to their test facility for a thorough appraisal, they managed to get it to produce some astonishing times, including 2.8 seconds 0-60.  Car and Driver claimed this made the new M5 “the quickest sedan we’ve ever tested”.  They also went on to explain how there is no turbo lag and an “instantaneous big whacks of power similar to a massive naturally aspirated engine. There’s no slush in the gearbox, either; the torque converter locks up almost as soon as you get rolling”, says Car and Driver.

As for Top Gear’s head-to-head, they distinguished BMW M5 from the Mercedes in several key ways.

“The BMW M5 is keener to knuckle down and be serious. Its 592bhp lags slightly behind the E63S, but it feels more agile, and to a greater degree than its slim 25kg weight advantage suggests. It favors assertiveness over aggression, and its steering is quicker, its pedals more responsive and its front tires more willing to bite. That also means it can snap a bit quicker than the Merc, which seems to slide in slow-motion. The M5’s engine has sound fed into the cabin, and it’s sharper and higher pitched. The thunderous AMG appears to be gargling its own mechanical components in comparison”, says Top Gear.

They also described the M5 as the more serious car, as well as the more “sedate cruiser”, also considering its media system superior to the Mercedes, finally naming the BMW the “more rounded, comfy car” thanks to its astonishing depths of engineering, making it a wonderful choice for an enthusiast and a thoroughly sophisticated model in every attribute worth consideration.
