Each time tuning company G-Power unveils its work, we could expect a tuned car that is significantly more potent than the standard unit it was based on. This has been the case for several of BMW’s high-performance cars – all of which were made more powerful by the incredible tuning work of G-Power.
The latest of G-Power’s works include, however, another German premium carmaker – Mercedes-Benz. For its latest project, G-Power has picked the Mercedes-AMG GT sports car. In the non-tuned form, the 4.0-liter twin-turbocharged V8 engine found in the AMG GT sports car only delivers 462 hp of max output and 600 Nm (440 lb-ft.) of peak torque.
This level of power already allows the AMG GT sports car to do a very quick sprint, accelerating from zero to 62 mph (100 km/h) in just 4.0 seconds while reaching a limited top speed of 189 mph. For many, this level of performance is already incredible. But the people at G-Power knew they could improve the dynamics of this engine and make the AMG GT sports car a better performer.
So, G-Power commenced its project. The tuner installed its own Bi-Tronik 5 high-performance plug-and-play module (€2,563 or $2,679) that links to the factory-side ECU (engine control unit). The power module’s microprocessor modifies the data provided by the vehicle sensors and then transmits this revised information to the standard ECU.
Thanks to this configuration, G-Power is able to ensure a great working harmony between the AMG GT’s original engine hardware and the Bi-Tronik 5 power module while keeping untouched both the diagnostic and the engine protection functions. Interestingly, since the Bi-Tronik 5 power module is installed outside the ECU of the V8 engine, it won’t be affected by any factory software update. In addition, since the Bi-Tronik 5 is a “plug & play” power module, the driver can employ it only when he or she feels like using it.
With the Bi-Tronik 5 power module, the V8 engine could now deliver up to 610 hp (448 kW or plus 148 hp) of output at 6,500 rpm and 755 Nm of torque available between 4,000 rpm and 5,500 rpm (plus 155 Nm). This level of power now allows the tuned V8 engine to dash from zero to 62 mph (100 km/h) in only 3.6 seconds.
Aside from the engine upgrade, G-Power also gave the AMG GT a revised front fascia. The tuned AMG GT rides on silver-finished Hurricane RR light alloys wheels (9.0 x 20 inches at the front, and 10.5 x 21 inches at the rear) wrapped in tires measuring 275/30R20 on the front and 305/25R21 at the rear. This Hurricane RR wheel-and-tire combo is being offered by G-Power at a price of €7,645 or $7,988.
