Mercedes-AMG Project One

At the end of 2016 Paris Motor Show , Mercedes-Benz announced the release of a new hypercar, presenting only an image teaser with the outlines of a future model ^{[4] [6]} . New illustrations were also presented at the CES Consumer Electronics Show. At the beginning of 2017, it became known that the car will be equipped with a 1.6-liter V6 engine, which has successfully proven itself in Formula 1 races on the Mercedes F1 W07 Hybrid ^[7] . Information about him was presented in January at the North American International Auto Show ^[4] . According to information provided by the company, it is known that the car body will be made of carbon fiber ^[4] , and the hypercar itself will receive active spoilers ^[2] . The front axle will receive a drive from the electric motor, and the torque vector will go where it will be possible to get the most benefit from it. The weight is expected to be about 1000-1300 kg ^[1] . The assembly of the hypercar will be carried out by the Mercedes-AMG division of Affalterbach and Brixworth of Northampton , UK , responsible for the Formula 1 powertrain.

At the end of January 2017, the Peisert Design Internet resource, based on public images presented by Mercedes-Benz , made a sketch of the possible appearance of the car ^[8] . According to the assumption of a number of print publications ( Car , Autozeitung magazines and others), the hypercar can be presented at the 2017 Frankfurt Motor Show on the occasion of the 50th anniversary of the Mercedes-AMG division ^{[2] [6] [9] [10]} . Presumably, one of the first owners of the new items will be Lewis Hamilton ^[10] .

At the Geneva Motor Show in March 2017, it became known from Tobias Moers that the company plans to release a total of 200 to 300 models ^{[4] [8]} , each of which will have a capacity of about 1000 horsepower and a mass of not more than 1000 kg. The car will be equipped with three engines: one gasoline ICE and two electric motors ^[5] . Melissa Witek, a Mercedes-AMG project manager in charge of hypercars, reported that a car exhibited in Switzerland had only 85% of the approved project completed ^[11] .

In April 2017, according to the Road & Track automobile magazine, it became known that Mercedes-AMG plans to release 275 units of the model. In addition, the publication reported that the German company stopped accepting orders in some countries, such as, for example, the USA (orders were accepted until March 17, 2017). Moreover, to place an order, potential customers had to be owners of Mercedes-Benz products, as well as to convince the representative that the car would really be used for movement, and not stored for a certain period of time in the garage with subsequent resale for profit ^{[11 ]} .

In mid-April 2017, the head of Mercedes-AMG, Tobias Moers, confirmed that the circulation of the model will be only 275 copies. He also noted that a large number of customers showed interest in hypercar. In addition, the company representative also said that before the start of mass production, the model will undergo sea trials not only on the company's test tracks, but also on racetracks. One of the members of the test team will be a British rider who plays for the Mercedes team , five-time Formula 1 champion Lewis Hamilton ^[12] . Tobias Moers also previously told Top Gear the cost of the hypercar, which is 2.275 million euros ^[13] .

At the end of May 2017, before the start of the 24-hour Nurburgring marathon, Mercedes-Benz presented the entire technical component of the car. It became known that a modified hybrid powerplant from a Formula 1 racing car was installed on the hypercar, similar to that used on the 2015 Mercedes F1 W06 Hybrid ^[14] . It is based on a 1.6-liter gasoline internal combustion engine in the V6 configuration, which, unlike the sports version, is equipped with a different crankshaft, pistons, and also an ECU.

The car was presented in September 2017 as part of the Frankfurt Motor Show ^[15] .

Exterior

The exterior of the hypercar has not yet been officially presented, only the general outline of the body has been demonstrated, in which something is reminiscent of sports prototypes performing in Le Mans in the most powerful category LMP1 ^[16] . The official images published by Mercedes-Benz show the rear of the car with a roof air intake and a characteristic fin fin, like racing sport prototypes. The presence of branded doors in the style of " gull wings " from the original SL-model of 1954 is also assumed.

The design of the car consists mainly of carbon fiber (chassis and body), as well as aluminum and other light metals (in the front and rear) ^[16] .

Engine

According to official information, the car will be equipped with a 1.6-liter hybrid power unit (gasoline ICE + two electric motors, one for each front wheel ^[16] ) with 6 V-shaped cylinders from the race car Mercedes F1 W07 Hybrid , the maximum power of which will be about 1000 horsepower. The engine will be able to rotate at speeds up to 11,000 rpm. The declared engine resource, according to the chief of the Mercedes-AMG unit, is 50,000 kilometers (replacement or repair will be carried out at the expense of the buyer) ^{[5] [17] [18]} . With such a power unit, the hypercar will accelerate from 0 to 100 km / h in 2.5 seconds. The maximum speed will be 355 km / h. In an interview with Evo magazine, Tobias Moers said that AI-95 or AI-98 gasoline can be used as fuel ^[16] .

The red zone of the power unit starts at 11,000 rpm (lower than 13,500 in the racing version). The declared thermal efficiency is 43% (for comparison, the same indicator for a 4.0-liter biturbo V8 engine is 25% ^[19] ). The idle speed is approximately 4000 rpm, which is also inherent in the sports version of the engine ^[14] . The mass of the power plant along with a 100-pound battery is 420 kg. Front electric motors can be activated without starting the engine and in this mode the maximum distance covered is about 24 km.

Batteries

To ensure the operation of the electric motor, the batteries used by the company on Formula 1 cars - “Motor Generator Unit-Kinetic” (MGU-K) and “Motor Generator Unit-Heat” (MGU-H) will be used. The MGU-K is mounted on the main propeller shaft and has a power of 120 kW (163 hp). This system is designed to rotate the rear wheels and restore kinetic energy during braking ^[20] . MGU-H is mounted on a turbocharger shaft and has a power equal to 80 kW (109 hp) ^[14] . Its purpose is to eliminate such a phenomenon as a “turboyama” (a delay in the set of engine revolutions due to inertia of the turbine) ^[20] . This system is also able to use the exhaust gas from the exhaust pipes, turning it into kinetic energy. Two more batteries will operate on the front wheels to support the all-wheel drive transmission, together providing a capacity of 161 liters. with. (120 kW) ^[21] .

The traction battery, which is located behind the front axle, is similar in design to what is installed in the car of the company for Formula 1. It uses the same chemistry, cells and connectors as the sports version, but its capacity is four times that which was done to achieve zero emissions ^{[22] [14]} . The batteries are collected by ABC, which is their suppliers for Formula 1.

Transmission

According to officially submitted information, Mercedes-AMG engineers will equip the car with a sequential (before the disclosure of technical specifications it was assumed that the gearbox would be robotic) 8-speed gearbox with one clutch, since, in their opinion, no preselective automatic transmission can control the power of the hypercar power unit ^[17] . Power transmission will be carried out on all four wheels ^[16] .
