New Audi RS6 vs BMW M5: video exclusive

► Audi RS6 vs BMW M5
► Video: Teutonic twin test
► A 1200bhp power struggle

We've already driven the new Audi RS6 Avant and know it's a fearsomely fast, capacious estate car that thinks it's a more bootiful R8 supercar. 

But how does it stack up against one of our favourite high-performance executives, the evergreen BMW M5? Only one way to find out. Across twisting Welsh mountain roads, we drive the two back-to-back.

The M5 is in Competition spec, which brings power to a heady 616bhp from its turbocharged 4.4-litre V8. That's more, even, than the very latest RS6, which musters 592bhp from its 4.0-litre twin-turbo V8. Make no mistake: both cars are ferociously fast, dispatching 0-62mph in around 3.5sec.

But is that ultra-performance actually usable in 2020? On Welsh roads famed for their slip and endless precipitation, can you actually enjoy all that muscle? A rainy Snowdonia is the perfect backdrop to our latest twin test.

Join our reviewer James Dennison in the film above - and be sure to sound off in the comments below. 

Stay tuned for the full magazine triple test, when we throw a Mercedes-AMG 4-Door into the mix too. Coming soon in the April 2020 issue of CAR magazine.
