World record: BMW Coupe with a top speed of 370 km/h

Creating the ultimate BMW, nothing less was the set target for the G-POWER engineers when they started to designe the G-POWER M6 HURRICANE CS.

The starting basis for this project is the currently most exclusive model in the BMW product range, the BMW M6. Due to the combination of this fantastic basis with the technical innovative products of G-POWER, it was able to create a sports car of superlatives. Powered by a V10 SK III RS twin-supercharger engine with 750 hp / 552 kW, which enabled the G-POWER world record car to achieve a top speed of 367,4 km/h, the G-POWER M6 HURRICANE CS has got what it takes to be a member of the super car league.

Further characteristics of the G-POWER M6 HURRICANE CS is the multipart widebody kit, the high performance Carbon-Ceramic break system, the individually adjustable suspension kit and last but not least the nifty 21 inch G-POWER wheels with MICHELIN tyres.After the G-POWER M5 HURRICANE RS broke the world record for the fastest sedan, G-POWER developed this idea to use this potential to build the world’s fastest BMW coupe, the G-POWER M6 HURRICANE CS.

For this project, the redesigned twin supercharger system of the world record car for the fast-revving V10 was used. Compared to the standard system, both belt-driven ASA T1-313 superchargers, each providing charge air for one cylinder bank, were replaced by larger ASA T1-316 models. They have the capacity to increase the volume of charge air by up to 25 percent but only a fraction of that was utilized in this engine. The air volume these chargers are capable of would theoretically be sufficient for a rated power output in excess of 900 hp. The pre-compressed air from both superchargers is cooled for maximum power yield in a dual-flow water-to-air intercooler painted G-POWER orange. This sophisticated cast-aluminum component replaces the stock airbox above the engine. Because of its close proximity to the engine it produces the same instant throttle response as the production engine, albeit with considerably more torque.

The inner workings of the ten-cylinder four-valve engine are optimized with forged high-performance pistons from Mahle that reduce compression. They have been precisely matched for weight and are much stronger than their production counterparts. The production piston rods and pins also had to make way for special components that can handle the much higher forces.

Further optimized mapping of the engine electronics also contributes to the increased power output of 750 hp / 552 kW, available between 7,500 and 8,000 rpm. The engine delivers its peak torque of 800 Nm at 5,000 rpm. The G-POWER M6 HURRICANE CS sets new performance records not just for top speed with more than 370 km/h. With sprint times of less than 4.4 seconds from rest to 100 km/h, 9.6 seconds to 200 km/h and 26 seconds to 300 km/h the nearly two-ton coupe is at the head of the pack in these categories as well.

Two tons and a top speed of 370 km/h naturally place extreme demands on the tires, which were mounted on G-POWER light-alloy wheels. Technology partner Michelin provided high-performance Pilot Sport PS2 tires in sizes 255/35 ZR 19 in front and 305/30 ZR 19 on the rear axle. These tires were the only ones capable of handling the extreme stress. In everyday driving the G-POWER M6 HURRICANE CS runs on 21-inch Silverstone Diamond wheels with size 255/30 ZR 21 and 295/25 ZR 21 tires, due to the capacity of the tires the top speed has to be limited to 340 km/h, than.

In addition to the most powerful BMW engine ever to power a street-legal BMW, favorable aerodynamic properties were of elementary importance. The needed body kit has to fulfill to function at once. First of all it has to generate enough down force to keep the G-POWER M6 HURRICANE CS on the ground at speeds of more than 300 km/h and secondly it responsible for transform the standard BMW M6 into a super sports car. That is why G-POWER designed a unique widebodykit made entirely from carbon fibre. In addition to producing the desired downforce it is also designed to supply much more cooling air. It consists of front apron, bonnet with vents, rocker panels, wheel arche attachments, rear aprons with diffusor and a rear spoiler wing.

At the same time G-POWER puts the BMW M6 on a diet and makes it lose weight bit by bit. The biggest share is taken by the G-POWER complete exhaust system made entirely form titan which lets the dynamic back pressure drop just like the weight. 24 kg are saved compared to the standard exhaust system.

In the vehicle interior G-POWER switches the standard front seats against racing seats made from carbon fibre, which ensure a perfect support for the drive in its fight against the centrifugal forces. Of course these seats are lighter than the standard seats as well and again the M6 has lost 24 kg.

Weight neutral, but not without effects is the G-POWER suspension package CLUBSPORT. It optimizes the road handling of the G-POWER M6 HURRICANE CS to perfection and is consisting of the continuously height-adjustable G-POWER coil-over RS suspension with nine selectable settings each for bound and rebound and the G-POWER anit-roll-bar kit for front and rear axle.

The option list of the G-POWER M6 HURRICANE CS ends with a true highlight: a Carbon-Ceramic break system with 6-piston calibres and brake discs with 380 mm in diameter. This heavy duty brake system delivers declaration rates beyond the gravity on a constant rate and at the same time are 50% lighter than the standard brakes.

The standout cockpit of the G-POWER M6 HURRICANE CS features a speedometer with 400-km/h scale, clear-coated carbon-fiber panels for dash, center console and doors, as well as an ergonomically shaped G-POWER sport steering wheel with especially pleasant perforated Kjerba Nappa leather.

The G-POWER M6 HURRICANE CS can be ordered as a complete car starting at 360.000 Euros.

After the G-POWER M5 HURRICANE RS with bi-supercharger engine and 750 hp / 551 kW broke the record for the “world’s fastest saloon car” at the end of 2008 with a speed of 367.4 km/h, G-POWER went one step further in 2010, taking the existing record to a new all-time best of 372 km/h with the next evolution of the same car – the M5 HURRICANE RR.

The 800 hp 588 kW V10 bi-supercharger engine familiar from the G-POWER M5 HURRICANE RR is now also available in BMW’s full-size coupé, making the G-POWER M6 HURRICANE RR the world’s fastest 4-seat Coupé.

The necessary power increase comes courtesy of a further developed version of the 750 hp / 551 kW SK III RS bi-supercharger system, with the 800 hp evolution featuring two ASA T1-316 radial supercharger. The charge air, which is pre-compressed inside the two superchargers, is cooled to performance-enhancing temperatures by the dual-flow, water-cooled charge air cooler system finished in G-POWER’s characteristic orange. This complex aluminium casting replaces the standard-production airbox on top of the engine and, because of its short intake channels, facilitates the same spontaneous throttle response as the series production engine, combined, however, with a substantial increase in torque.

The inside of the ten-cylinder four-valve engine has been optimised by lightweight, precisely balanced Mahle high-performance forged pistons with lower compression and increased stiffness. Dedicated components are also required in place of the series-production con rods and piston pins, which are not specified to handle the significant increase in forces. Modified mapping for the engine electronics also contributes to the higher peak output of 800 hp / 588 kW at between 7,500 and 8,000 rpm. The maximum torque of 800 Nm is generated at 5,000 rpm.

Of course, the outstanding performance figures delivered by the G-POWER M6 HURRICANE RR are not limited to top speed alone. With less than 4.35 seconds from 0–100 km/h, the almost two-tonne coupé sets a standard that is just as impressive as the 9.5 seconds it takes to 200 km/h and the 24,9 seconds to the 300 mark.

Alongside the most powerful BMW engine ever to power a road-legal BMW M6, aerodynamics also played a fundamental role. Thus, the HURRICANE RR has been equipped with a G-POWER carbon-fibre front skirt and a rear spoiler for greater aerodynamic downforce at high speed.

The G-POWER M6 HURRICANE RR maintains its contact to the road with 20-inch G-POWER SILVERSTONE CLUBSPORT forged wheels clad in 255/35 ZR 20 and 285/30 ZR 20 rubber. Optimisation for performance was, of course, a priority in this department, too. Consequently, the all-new SILVERSTONE CLUBSPORT forged alloy wheels, measuring 9.0 x 20 inches and 10.5 x 20 inches, are no heavier than the series-production wheels, despite their far greater dimensions.

Further contributors to the high-speed capability of the M6 HURRICANE RR are the G-POWER high-performance braking system and the G-POWER RS coil-over sports suspension, with 9-way adjustability for compression and rebound plus infinitely variable height adjustment.

The exclusive nature of this automobile is clearly indicated by a tachometer that measures up to 400 km/h, visible carbon-fibre panelling for the dashboard, centre console and door trim, as well as the ergonomically shaped G-POWER sports steering wheel upholstered in perforated and highly tactile Kjerba Nappa leather.

The G-POWER M6 HURRICANE RR is available for order as a complete vehicle from G-POWER in Autenzell, Germany. The same G-POWER engine technology is also available in a 750 hp version for the current BMW M5 and M6. The G-POWER SK III RS bi-supercharger engine conversion with 750 hp / 551 kW is offered at a price of EUR 56,000 (net plus assembly).
