Plus 745 hp and a 'track-capable' chassis.

The 4.0-liter, twin-turbo V8 motor under the long, long hood of the Mercedes-AMG GT is ripe for tuning, and plenty of companies have shown off their hopped-up iterations.

Piecha, RevoZport, Mansory, and RennTech have all had a go. Even AMG itself has got in on the act, unveiling the hardcore, 577 horsepower (430 kilowatts), rear wheel steering-equipped GT R.  

And now we have American outfit Dime Racing, which has produced one of the most powerful tuned AMG GTs to have hit the streets.

Dime is something of an AMG specialist and races a GT3-spec SLS in the Pirelli World Challenge. So the engineers there know what they’re doing when comes to tuning engines and fettling chassis.

The Dime Racing Edition AMG GT produces a claimed 745 hp (556 kW) through unspecified means, but bet on bigger turbos, hardened internals and a bespoke management system.

Likewise, Dime is vague on the details of the upgraded suspension and cooling. At least the new front and side splitters, huge rear diffuser, and enormous wing are obvious. No claims have been made about their performance, though.

Speaking of which, Dime hasn’t mentioned a 0 to 60 miles per hour (100 kilometers per hour) time or top speed, either. For reference, Mercedes claims the GT R dispatches the sprint in 3.6 seconds, and runs on to 198 mph (319 km/h). So it would be reasonable to expect Dime’s car to reach 60 in the low three-second range, and top out well beyond 200 mph (320 km/h).

The company explains all of the modifications “create a unique track-capable experience that’s bred from Dime’s extensive experience in various racing series.” Should be good, then.

Dime will build just 100 AMG GTs every year, each with its own unique VIN number. It’s even sold through selected AMG dealers around the United States and comes with a “bumper to bumper” warranty.

The price? $150,200, which isn’t quite reasonable of a car with this kind of power and a warranty. And it includes a free Växjö watch, a rather handsome timepiece made by former F1 driver Stefan Johansson.
