A fast car without a roof has something raw. The latest build from G-Power takes the BMW M4 Cabrio and turns it into something much more serious: the G4M-Bi-Turbo convertible, a machine with supercar numbers and the ability to enjoy it under an open sky. The visual upgrades are sharp, but not exaggerated. A GP Venturi carbon hood, a GP-shuriken carbon grille and a bumper corner and a set of GP-Hurricane RR Fored bikes are characterized without screams. Other add-ons, like splinters, wings or repeated internal standing, but the real transformation is under the bonnet.
The GP-720 package
In this M4, GP-720 performance software is carried out by G-Power, with the 3.0-liter twin-turbo inline-SIX raising to 720 hp (529 kW) and 850 Nm (627 LB-FT). This is almost 200 hp more than BMW’s own M4 competition. The top speed increases to 330 km/h (205 miles per hour) and moves the car firmly into the area, which is usually reserved for exotic. The backing IT UP is the G-Power DeeptONE stainless steel exhaust, which is coordinated for a deep burle and is equipped with a striking quad tail tube setup-two 100 mm pointed, paired with two even larger 110 mm tips, all of which are completed in coal fibers. It is the type of noise that you will be confused with no stock.
With these numbers, the G4M-Bi-Turbo convertible is sitting with some of the fastest cars from the past two decades. The difference is that you drop the roof and hear the turbos and the exhaust outdoors outdoors. An experience that not many supercars can match with a closed roof.
The interior shows that this G4M G4M is based on the cross-previous M4 convertible; Thanks to the smaller LCD screens with iDrive 7. You will also see that the use of carbon fiber spreads over the entire dashboard and the center console while the steering wheel receives its own carbon fiber inserts.
How much electricity costs
The GP-720 upgrade is not cheap 35,700 € ($ 41,630) in Germany. Lower levels are also available: 600 hp, 620 hp, 650 hp or 670 hp, from € 3,685 ($ 4,295). The 700 PS package tested here is in the middle at € 14,900 ($ 17,375). It is a wide range, but even the entry level has the price of a decent used car.
The standard BMW M4 convertible is already one of the most comprehensive open-top performance cars on the market. The version of G-Power not only sets up the volume, but also around the limits of the car. With 720 hp, 330 km/h high speed and a roof that disappears, the G4M-Bi-Turbo convertible is less subtle improvements than the type of performance that it was always capable of.
