G-Power BMW 40i Tune  for M240i/340i/440i

G-POWER GP 40i Limited Edition:

Exclusive customization for the BMW M140i/M240i and 340i/440i

The B58B30 in the 40i models is undoubtedly the spearhead of the latest gasoline powered modular engines from BMW. Becoming an increasingly rare example even in Munich, the straight six-cylinder engine, runs between 326 and 340 HP from the 3.0l capacity in the BMW M140i/M240i and 340i/440i depending on the stage of development. Just like the legendary, high-revving V8 and V10 from the M models, G-POWER once more shows its passion for charismatic BMW engines and honors the straight six power unit with an exclusive customization program: the GP 40i Limited Edition.

This package is strictly limited and only 50 vehicles will feature this exclusive customization.

This not only means an increase of 94 HP and 150 Nm as opposed to the standard model, but also another 20 HP and 20 Nm on top compared to regular Performance Software V1!

This power enables the 440i (F36) shown here in the

GP 40i Limited Edition to accelerate to 100 km/h in just 4.2 seconds, while the maximum possible speed reaches well beyond the 300 km/h mark. A stainless steel rear muffler featuring two carbon tailpipes of 90 mm in diameter rounds off the technical modifications on the Gran Coupé.

The GP 40i Limited Edition also includes a set of high-quality velour carpets for the interior and luggage compartment bearing the company’s logos or lettering, as well as the G-POWER identity package, which includes interior badges with serial numbers, license plate holders, as well as emblems and logos for the engine cover, front hood, trunk lid and vehicle key. Exclusive to the GP 40i Limited Edition, the decor set which is also included reinforces the dynamic G-POWER design of the particular car further with additional logos and lettering for its flanks, hood and tailgate.

In addition to the limited customization package, G-POWER has also mounted a set of the popular 20 inch HURRICANE RR forged wheels on the 440i Gran Coupé. The lightweight twin-spoke wheels are fitted with high-performance 245/30 R20 tires. On top of that, a G4 – RS coilover suspension has been installed, which enhances both the look thanks to lowering and handling.
