The American racing, research and automotive development company's latest turnkey car promises nearly twice as much horsepower as a standard Mercedes-AMG GT and 10 times the exclusivity of even the upcoming range-topping 320-km/h GT R model.

The DIME Racing Edition AMG GT promises an output of 745hp, that's 283hp up on the standard GT's 4.0-liter twin-turbo V8 and 168 more than even the 2017 GT-R will be able to deliver.

What's more, the GT-R will be limited to 2000, which will make it comparatively common compared with the DIME. Just 100 are planned over the next 12 months, and each will have a special VIN number for future collectability.

The final touch will be a complementary Stefan Johansson Växjö watch (the Swiss watch company founded by the renowned Swedish racing driver) complete with a serial number matching that of the finished car.

Unlike a number of companies in the hot-rodding and customization community, Huntington Beach, California-based DIME's upgrades and improvements aren't simply exercises in carbon-fiber excess or taking a screwdriver to a car's supercharger or turbos and plugging a PC into its on-board computer.

Instead, any adjustments or improvements it offers customers for their road cars or individual race cars were honed on the track -- particularly in the GT3 class, where DIME competes with cars developed in-house based on AMG-powered Mercedes.

So, when the company announces it can do something special to the already special Mercedes-AMG GT, it should generate a ripple of excitement among those that know. It's also why, as well as boosting horsepower and engine breathing, each car will get a completely revised suspension set-up, a new cooling package, unique wheels and reworked aerodynamics, the most prominent of which is a huge, adjustable GT3 class rear spoiler.

Best of all, all of the refinements will not alter the car's classification. It will still be a road-legal ride.

Prices for the DIME Racing Edition AMG GT will start at $150,000 plus the cost of a donor Mercedes-AMG GT, but for that outlay, each car will come with what the company describes as a "bumper-to-bumper" warranty.
