It was about time. After the first video reviews of AMG’s latest GT S, we now have the chance to see how good is the 503hp coupe against the mighty 911 Turbo.

EVO magazine drove them against the clock in the stunning Anglesey circuit with a clear winner on this track battle.

Although very few of the owners will ever take them on a track, this battle demonstrates how the differences between the powertrains of the two rivals translate on pure performance terms.

On the yellow corner we have a rear-wheel drive, front-mid engine 503hp Mercedes and on the red corner a four-wheel drive, rear-engine 513hp Porsche.

Which one wins? Watch after the jump.
