A higher specification Mercedes-AMG GT prototype has been spied conducting preliminary testing.

A higher specification Mercedes-AMG GT prototype has been spied conducting preliminary testing.

Featuring a widened and more aerodynamic body, the prototype being tested by Mercedes-AMG is most likely a road-going version of the track-only AMG GT3 taking into account AMG CEO Tobias Moers has previously said the range-topping Black Series derivative won't be out in the near future. Chances are the car spotted in these spy images is a lighter and more powerful version of the AMG GT S.

Likely competing with the Porsche 911 GT3, the road-legal Mercedes-AMG GT3 (will get different name) will continue with the same twin-turbo V8 4.0-liter engine but its output is going to increase compared to the AMG GT S which has 510 HP (375 kW) and 650 Nm (479 lb-ft). Aside from getting a power bump, the new version will also be lighter so expect weight to go down a bit from 1,570 kg (3,461 lbs) of the AMG GT S.

Since the AMG GT S needs 3.8 seconds to cover the 0-62 mph (0-100 km/h) sprint, the hotter version should shave off 0.2 seconds. Aside from the more power less weight combo, the road-going GT3 version will get a front splitter, canards and a new rear wing which will be different from the one fitted to the AMG GT Edition 1 version.

This new variant will probably be out sometime next year and is going to cost significantly more than the AMG GT S which in Germany kicks off at €134,351.
