We talked with senior AMG officials to understand that F1 technology will reach the level of the powerful AMG GT Coupé and AMG C-Class this year.
üThen, the brand’s stone fortress was admired by millions of consumers. Petrol head (Read fans of cars with gasoline engines, almost always sporty) as Electrification The car takes irreversible steps.Now it’s here AMG About to start your The first 100% electric model (Still this year) based on the new EVA (Electric Vehicle Architecture) platform and The first plug-in hybrid car High performance (PHEV) with label Electronic performance.In the latter case, the technical principle Derived from the Project One supercar (We call it the Mercedes F1 highway, In the hands of the first customers in a few months)move to AMG GT 4-Door Coupe and C-Class AMG That will also hit the market 2021.
Of course, the supercar is designed for other “flying”. It has five engines: two electric motors on the rear axle and the rear wheels. 1.6-liter V6 engine (from F1 racing car) The first two, one Maximum power exceeds 1000 hp, 350km/h Maximum speed, Reach 0 to 200 km/h in less than 6 seconds (Faster than Bugatti Chiron), and the price matches Over 2.8 million EUR.
About the first Fully electric AMG, The file will be submitted this year, only they will use engine (One permanent magnet synchronous motor for each axis, so it is four-wheel drive), it will use one 22 kW car charger, Accept direct current (DC) load Up to 200 kW.In addition, they will be able to achieve Performance level of models equipped with a 4-liter V8 twin-turbo engine. That is, for a sprint from 0 to 100 km/h under 4 seconds, the maximum speed is 250 km/h.
In order to adapt to the ever-changing era, AMG remodeled its headquarters (located in Affalterbach, on the outskirts of Stuttgart), which now includes a test center for high-voltage batteries and electric motors, and a center for the production of hybrid engines. in.On the other hand, it Strengthen cooperation with Mercedes-AMG F1 Petronas team engineers In this way, technology transfer can be carried out in the most direct and fruitful way.
“AMG hopes to keep up with the development of the times Electrify your products without giving up positioning. We will continue to produce high-performance cars to make profits. Young customer base one left Higher proportion of customers“, CEO Philipp Schiemer In an exclusive zoom interview, in this interview, key technical concepts are introduced Jochen Hermann, Technical Director (CTO) AMG.
The first innovation and Motor placement, As Hermann explained: “Unlike traditional plug-in hybrid cars, in this new system, the electric motor is not installed in the front part between the gasoline engine and the transmission, but On the rear axle.This makes the weight distribution between the front and rear of the car become more fair.Moreover, the speed at which power is distributed to each wheel on the rear axle through the limited slip differential is faster, which makes Cars ground power faster, Obviously benefited from Turning agility“.
This Rear motor (Synchronous permanent magnet, the maximum performance is 204 CV and 320 Nm) Is the so-called Electric unit (EDU),by Shift two gears And electronic self-locking device.Motor generator replacement At 2 mph at 140 km/h Maximum (corresponds to a motor speed of approximately 13,500 rpm).
One of the reasons the AMG engineering team is proud of New high-performance battery (Also installed on the rear axle), composed of 560 battery cells, Continuous power 70 kW or peak 150 kW (Last 10 seconds), and it was developed “at home” with the strong support of the Mercedes F1 team, as Hermann promised: Technically close to the kind used by Hamilton and Bottas cars,able 6.1 kWh, weighing only 89 kg. Its energy density reaches 1.7 kW/kg, which is about twice that of a high-voltage battery that is not directly cooled in a traditional plug-in hybrid system. “
Explain succinctly, the basis of the high-performance 400-volt AMG battery is Direct cooling: For the first time when Permanently wrapped in refrigerant Based on non-conductive liquids.This 14 liters of soda water Circulate from top to bottom in the entire battery, through each battery (with the help of a high-performance electric pump), and also flow through Oil/water heat exchanger Connect directly to the battery.
In this way, the temperature may always remain at 45 degreeRegardless of the number of charging/discharging, it is performed in a stable and consistent manner, which is different from a hybrid system with a conventional cooling system in which the battery loses its performance as the temperature rises. As the technical director of AMG explained, “Even in a very fast lap on the track, when acceleration (discharge the battery) and acceleration (charge the battery) are frequent and intense, the energy storage system can still maintain its performance.”
Same as F1, due to Powerful energy recovery system And because there is always one Accelerated power reserve Fully or medium, even when the battery is low. The system provides the usual driving mode (Tram speed up to 130 km/h, comfortable, sporty, sport+, race and individual), you can adjust the response, steering feel, damping and sound of the engine and gearbox, and you can use the controls on the center console or the buttons on the front of the steering wheel to select.
