The tuning specialist has decided the summer needs convertibles such as the BMW M4 and since the Bavarian ride is already a thrill to ride, they just needed to ramp up the power delivery to make things look spectacular.
Now the G Power BMW M4 Convertible has under the hood a Bi-Tronik 2 V1-ECU remap which has easily taken the total power of the 3.0-liter BMW M TwinPower Turbo six-cylinder engine to 520 horsepower and 516 pound-feet of torque. This is a nice 89 hp and 110 lb-ft of torque bump but G Power can deliver even more and its specialists opted on a bigger turbocharger, new downpipes, and a titanium exhaust system with carbon fiber finishers. This has enabled the high performance convertible to return 600 horsepower and 545 lb-ft of torque – a sizeable hike of 169 hp and 140 lb-ft of torque.
This makes playing around in the M4 Convertible in sunny areas of the planet even easier, as the extra grunt and the removal of the electronically-controlled speed limiter has enabled the BMW ride to 62 mph (100 km/h) in just 3.7 seconds on its way to a new maximum speed of more than 198 mph (319 km/h). Since all that power needs to come with a measure of responsibility – and given that an M4 doesn’t have Spider senses – the tuner has also installed a coilover suspension and 21-inch G-Power Hurricane RR forged alloy wheels shod in the necessary high-performance tires. By the way, if you like to play Lego with your car, the components can also be purchased individually – the modifications to the car in the gallery costing the owner more than $25,295 (€22,332).
