GC Automobile GC10-V8 race car based on Bmw 1-Series M Coupe

Global Concept Automobile, also known as GC Automobile unveiled today the GC10-V8 race car based on the Bmw 1-Series M Coupe. For those who don’t know, GC Automobile is a France-based racing team which also designs, builds and races silhouette race cars. As you can see from the photos, the car kept the front and rear ends of the Bmw 1-Series M Coupe, while the rest is completely changed.

The new GC10-V8 comes with a new body kit with wide fender flares as well as an impressive rear spoiler and rear air diffuser.

And if you thought that this is just a kit you have to know that you are wrong as everything on the GC10-V8 is functional including the roof scoop which was designed to redirect air into the intake. The big surprise is under the hood, where the standard 3.0-liter inline six was replaced by an American Chevy V8 engine tuned by Sodemo Development capable to deliver 550 hp.

This power is delivered on the road by the 18″ wheels with suspension handled by a 3-way OHLINS suspension system. For those who don’t know, the standard Bmw 1-Series M Coupe delivers 250 kW/340 bhp and a maximum torque of 450 Nm, and it can sprint from 0 to 100 km/h (62 mph) in just 4.9 seconds, to 200 km/h (124 mph) in 17.3 seconds and has a top speed of 250 km/h (155 mph).

In creating the new BMW 1-Series M Coupe, the engineering team needed to hurdle a number of challenges. One of these was how to make sure that this luxurious and powerful coupe would deliver remarkable handling response to result in high performance while ensuring that total weight was kept under control. To answer this, the engineers used the aluminum suspension, first made for the present M3. They also brought it to its test center at Nϋrburgring Nordschleife, tuned it specifically for the 1-Series M Coupe.

The use of aluminum is not limited to the suspension as almost all of the components on the front end are composed of aluminum as well. These include the swivel bearings, front struts, and central subframe. Underneath the engine, an extra thrust panel has been fitted in allowing the front section’s lateral stiffness to be fully maximized. Being a BMW model, it is rather clear that when the BMW M was first designed, it began with setting up its major parts in a way that it would be able to attain an almost perfect balance for the front and rear, or about 51.7/48.3.

Total length is at 4,379 mm (172.4 in), which means it is longer compared to the 1988 M3 by 33 mm (1.3 inches). It is even wider by 122 mm (4.8 in) with width at 1,803 mm (71 in). Wheelbase is at 2,659 mm (104.7 in), which is larger compared to the 1988 M3 by 3 in but the same as that of the 2011 BMW 135i Coupe. Despite that, the 1-Series M Coupe is longer by 5 mm (0.2 in), wider by 53 mm (2.1 in), and taller by 13 mm (0.5 in).

Meanwhile, the track is the same for both the front and the rear at 1,542 mm (60.7 in), but compared to the 2011 BMW 135i Coupe, it’s wider by 71 mm (2.8 in) on the front and by 46 mm (1.8 in) on its rear. Preliminary weight has been found to be lower by 35 kg (77 lbs) DIN.

Overall DIN weight is estimated to be 31,495 kg (3,296 lbs).Since the track is now wider, the brand made sure to widen as well the rear quarter panels and the fenders before placing it in a unibody made of high-strength steel. Utilizing a metal roof panel, this new model, when compared to the 1-Series versions with the moonroof, has a weight that is lower by 15 kg (35 lbs).

This moonroof will not be available for the 1-Series M Coupe as it has been designed to be a performance-oriented model from BMW. Because of this lower weight due to the roof, the center of gravity is lowered as well and thus enhances the driving dynamics. This also allows for the headroom, or in some cases the helmet room, to be fully maximized.
