Mercedes-AMG will bring to the Project One Formula 1 to the road. The hypercar, still disguised as a show car, sustaining over 1,000 horsepower and runs over 350 kilometers per hour. Premiere it at the IAA 2017th
- Engine Technology from Formula 1
- The drive concept
- Cockpit in motorsport look
Hyper Cars have come in recent years in fashion. Porsche has one built with the 918 Spyder. Ferrari with the LaFerrari. McLaren with the P1. For this, the armada of Koenigsegg. Aston Martin is working with the Formula 1 team Red Bull at one. And even in the halls of Mercedes-AMG created a prestige object that is called Project One, and the technology from Formula 1 to put on the road. 275 Happy at a price of 2,275,000 euros. Plus tax. Power depending on the tax rate 2.7 million euros. And so the Beast sounds when starting (from 4:00 minutes's interesting):
The price is a problem? Of course not. "Since we have shown the first teaser, the phone in Affalterbach no longer stands still!" Chatted Daimler CEO Dr. Dieter Zetsche at the world premiere in Frankfurt out of school. Means that the planned 275 Project One probably have already been sold.
The Project One, the first issue the Swabians show car at the IAA, is based on a carbon-fiber monocoque. Behind the passenger compartment, the heart beats. A 1.6-liter turbo-V6 in mid engine design that does so in racing cars W08 of Lewis Hamilton and Valtteri Botta service. neumatic instead of mechanical valve springs enable a maximum speed of 11,000 / min. Topic Lewis Hamilton: The drove the Project One trial in Frankfurt on stage. But for the next race, he would rather take back the W08 still. The first production Project-One was with him but in the best hands, there was finally his boss Dieter Zetsche on the way.
The high-revving concept sounds more like a motorcycle than to street sports car, reached in the top of the power values but not quite the level of Formula 1 where the crankshaft rotates reasons of efficiency from 12,500 to 13,500 times a minute. Permits would be even 15,000 / min. A limited fuel flow of up to 100 kg of fuel per hour but forces the engineers to compromise. therefore, they also limit the boost pressure to approximately 4 bar.
Superplus place racing fuel
With these restrictions, the hypercar does not deal with. It can burn as much Super Plus (instead of racing fuel) until the tank is empty, and so strong boost, as permitted by the AMG engineers. 11,000 revolutions per minute are i the series but taboo.
The speed limit but ensures a longer shelf life. An engine that is designed to only around 4,000 kilometers as in Formula 1, customers would not be reasonable. AMG puts the first revision laid 50,000 kilometers. An electric turbocharger supercharged intake air for the four V6 with overhead camshafts, which drive spur gears. Turbine and the compressor are in this case separated. One wheel sits in the exhaust, the other in the intake tract. They are connected by a shaft.
At this wave, the first of four electric motors located. This electrical machine, called MGU-H for motor generator Unit Heat, one hand operates as a drive to plug Turbo holes, on the other hand as a generator to fill the batteries. In the latter case, the MGU-H of the energy of the hot exhaust gases operated. The second electric motor is MGU-K (Motor Generator Unit Kinetic). It converts kinetic energy during braking into electricity and is connected via a spur gear drive directly to the crankshaft. The MGU-K developed 120 kW (163 hp). With this configuration, the drive Formula 1 car has about 950 horsepower in qualifying mode.
Mercedes-AMG Project One with four electric motors
At the front axle AMG hangs two more electric machines. Both be coupled via a reduction gear to the wheels. These electric motors, each releasing 120 kW, so two additional MGU-K are practically, there is not in Formula 1, and let the Hypercar on the paper to be stronger than the racing car. The powertrain operates with a voltage of 800 instead of the usual 400 volts, which will allow, among other things particularly fast charging processes of the plug-in hybrid. The Ansteckvorrichtung this is on the right side of the vehicle. The fuel cap, Mercedes-AMG below on the left.
Exact performance conceals AMG. It is said that the hypercar strip over 1,000 hp. Torque? No information. There are, however, by supplier ZF, builds the couplings for Formula 1, a guideline. Which provides for the F1 powertrain: over 1,200 Nm. For this, the torque of the two electric motors would theoretically come to the front. In Formula 1, the output of the MGU-K is limited to a maximum of 200 Nm. The top speed estimated AMG dare to over 350 km / h. These are regions where play Lamborghini Aventador and Pagani Huayra. Bugatti Chiron, Koenigsegg Agera and Regera RS race even more than 400 kilometers per hour. Null 100 km / h? Rumor has to 2.5 seconds. So Chiron level. The 200 km / h to be covered by six seconds.
Larger batteries than in Formula 1 car
The battery packs in the underbody correspond to the structure of the cells and on the arrangement of the memories from the F1. However, AMG increases the storage capacity by four times. Thereby, the battery weight increases from 20 to 25 (F1) to about 100 kilograms. The weight by weight of the drive unit goes up to around 420 kg of at least 145 (F1). To the total weight Mercedes-AMG provides no information. Therefore also the power to weight ratio can not be calculated.
The Project One allows different driving programs, including an all-electric mode. Then only the electric motors toil at the front and bring the AMG good 25 kilometers. The electric motors on the front axle to brake the wheels and speed, can thus torque vectoring (torque vectoring). In passive mode, they collect up to 80 percent of braking energy. If the pilot obtains full power, the Project One is a four-wheel drive. an automated eight-speed transmission is used as a power transmission. A dual-clutch transmission or a converter would have been too heavy. The transmission from Formula 1 was not an option. Because it would be too noisy and rough for general traffic.
Cockpit with Formula 1 spirit
Active aerodynamics solutions such as the gills on the top of the front wheel arches and the two-part, extendable rear wing will also provide superior driving dynamics as the pushrod suspensions. The struts enable the spring / damper units.
The hypercar is the front on 19-inch wheels. Then you pull from Michelin specially designed Cup tires (Pilot Sport Cup 2) in size 285/35. the technicians assemble slippers size 335/30 ZR20 at the rear axle. For comparison, the tire size of the Mercedes-AMG GT R: 275/35 ZR19 and 325/30 ZR20. The 10-spoke forged aluminum wheels with central locking device was developed new. They have a radial, aerodynamically efficient designed partial cover of carbon. This should improve the aerodynamics and press the drag coefficient by a better flow around the wheel. At the same time three flat ventilation slots per spoke section provide an optimized heat dissipation from the brakes. A carbon-ceramic brake system delays the Hypercar.
The look of the Mercedes-AMG Project One characterize large air holes that run along the entire front bumper, narrow LED lights, an advanced cockpit, a skylight, a subsequent shark fin and a large diffuser. The air box on the roof supplies the engine with fresh air. The rear window allows a view of the V6 Turbo and the rear pushrods. Through the inlet air shafts, so-called NACA ducts, penetrates cooling air to the engine and transmission coolers. In addition to the central tailpipe AMG placed two small tubes. They mimic the wastegate tubes from the formula 1, in which a portion of the excess pressure turbine is passed to allow the V6 engines are louder. For road use, engineers must post-treated exhaust gases and insulate the noise a bit.
In the cockpit, the spirit of Formula 1 is dominated However, the cockpit takes two people. The bucket seats can not be adjusted in the longitudinal direction. For this, the driver can adjust the steering wheel, the pedals and the backrest. The steering wheel with integrated airbag is flattened top and bottom - as in a race car - piled over the first of two ten-inch screens. About the sparse center console AMG fitted the second. A rearview mirror in vain. Instead there is a Mirrorcam the headlining, which records the driver what is happening in the rear. A classic mirror would not be sufficient through the fin on the roof due to limited visibility. The paneled doors carbon is drawn to loops. Smaller items can cram into storage compartments the passengers. The hypercar also has air conditioning on board. The windows electrically drive down and up again.
