Performance boost costs less than $4,200.

The Mercedes-AMG GT is pretty impressive but that hasn't stopped Lorinser from developing a new tuning program for the high-performance model.

Described as a "vigorous power upgrade," the tuning program consists of a new performance module which fits both the AMG GT and the AMG GT S.  The module costs $4,148 (€3,650) and enables the biturbo 4.0-liter V8 engine to produce 595 horsepower and 553 pound-feet of torque.  The extra power allows the cars to run from 0-62 miles per hour in 3.6 seconds, 0-124 mph in 10.1 seconds, and 0-186 mph in just 27.3 seconds. 

Styling changes are limited but the company recommends a new set of RSK 8 light-alloy wheels which measure 20-inches up front and 21-inches in the rear.  The three-piece forged alloy wheels are available in black or gold and pricing starts at $12,986 (€11,424) - excluding the cost of tires.

For those brave enough to drive the car in winter conditions, the company offers a winter tire and wheel package which adds 19-inch RS9 light-alloy wheels with all-season tires.

The Mercedes-AMG GT S starts at $129,900 and has a biturbo V8 engine that produces 503 hp and 479 lb-ft of torque.  It is connected to a seven-speed AMG Speedshift dual-clutch transmission which enables the car to run from 0-60 mph in 3.7 seconds.
