Mercedes-AMG E Performance, Specs, Batteries, & Details, hybridization in power

Mercedes-AMG begins its green shift with the unveiling of two new electrically assisted hybrid powertrains. We first discover a V8 and a 4-cylinder that the manufacturer has developed together with the F1 team.

After the 53 versions, we will soon see under the hood of some AMG models engines that Mercedes-Benz has developed in partnership with the Formula 1 team .
At the moment, Mercedes-AMG is not particularly familiar with the concepts of fuel economy and reduced consumption. There are 53 versions that come with electric assistance, but we are still far from the full potential of electrification. During the year 2021, Mercedes-AMG will enter the 21st century in terms of mechanics with the launch of two new highly hybridized engines, a V8 and a 4-cylinder.

Born from F1

First, it is important to know that we are talking here about engines developed entirely by AMG, it is homemade. The Formula 1 team as well as AMG’s F1 specialists who work in the high performance powertrain department joined with engineers from Affalterbach in the design of the technology. So you can’t expect anything ordinary.

AMG maintains that there are two foundations to this strategy. First, we offer an independent hybridization system that can be added to almost all types of engines in the AMG family. This pillar bears the name E PERFORMANCE. Second, AMG supports the design of performance versions from Mercedes-Benz’s platform dedicated to electric vehicles, the EVA (Electric Vehicle Architecture). Collaboration with the EQ division will therefore be very important.

According to one of the heads of AMG, Philipp Schiemer, the approach could not be clearer: “With our new strategy, we are transposing our DNA into an electric future. Our performance hybrid vehicles, fully developed in Affalterbach, already outperform our current models in dynamism and do full justice to the technology and the E PERFORMANCE badge. With the 100% electric drifts based on the Mercedes-EQ, we continue to expand the offer with the electrification of the range.

Yes to hybridization, but performance

AMG embraces hybridization, but on its terms. All development is done by the performance division and according to its criteria. Therefore, we retain a fairly traditional strategy: heat engine at the front (4-cylinder or V8) and electrical hardware at the rear. In this way, it is easier to maintain the balance of the masses, an essential criterion for driving pleasure. All the better if that happens, but AMG is not necessarily aiming for lower fuel consumption. It gets a 10% drop, but the goal behind electrification is power gain and instantaneity.

Only high technology

We thus find a synchronous motor with permanent excitation with a peak maximum power of 201 horsepower (150 kilowatts) and a torque of 326 pound-feet (320 nanometers) on the rear axle. Generally speaking, permanent power remains at 95 horsepower (70 kilowatts). Not being in contact with the gearbox, it sends power directly to the wheels as needed (AWD, acceleration, torque vector). Thanks to the contribution of all-wheel drive, it is even possible to send a certain part of the power to the front wheels through the cardan shaft.

Mercedes-AMG E PERFORMANCE

The electric motor operates using an integrated 2-speed transmission. The second gear is only changed from a speed of 140 km / hour, when the engine reaches its maximum speed of approximately 13,500 revolutions / minute.

The battery, the heart

The design is also entirely up to the engineers at AMG. So we don’t do business with companies like SK Innovation or LG Chem. Integrated into the rear of the car, the battery has a capacity of 6.1 kilowatt hours at a voltage of 400 volts. Each of the 560 lithium-ion cells is cooled by non-conductive liquid separately from one another. This makes it possible to constantly maintain an ideal temperature of 45 degrees thanks to the work of a high-pressure cooling pump. AMG maintains that the contribution of this system makes it possible to completely abuse the engine on the track without the electric technology running out of steam or losing power and efficiency.

A new way of driving

AMG is integrating a new driving mode into the long list that already exists, “Electric”. In this case, depending on the mechanical configuration, it is essentially a rear-wheel drive. It will be possible to drive up to 130 kilometers per hour without using gasoline. Although the possibilities and the occasions will be rare, in the event of loss of grip of one wheel, through the gimbal, it will be possible to send power to the front wheels. On the other hand, in such situations, there is a good chance that it is the heat engine which enters the dance.

When it comes to the recovery of kinetic energy, AMG offers 4 charge levels. The first, level 0, leaves the wheels free just like a gasoline car. Level 1 will provide a bit of noticeable resistance to the conductor. At level 2, the vehicle will have an actual decrease in speed without coming to a complete stop. Level 4 is similar to one-pedal driving as in some electric car. In this case, there is no need for a button on the brake pedal anymore, the resistance is strong enough to immobilize the vehicle by modulating the pressure on the accelerator. For a strictly hybrid vehicle, this is a first.

It will push, watch out for 0-100 km / h!

AMG is embarking on more serious hybridization with the arrival of new versions including the AMG GT sedan whose expected power could exceed 800 horsepower. More reasonably, when it comes to the turbocharged 2.0-liter E PERFORMANCE 4-cylinder, the C63 would likely get it first. AMG maintains that even reducing the number of cylinders in half, horsepower and efficiency will be superior to the current V8. The numbers speak for themselves: the current 4.0-liter V8 develops 503 horsepower while the 2.0T E PERFORMACE 4-cylinder will be able to go up to 644 horsepower. The sprint from 0 to 100 km / hour is planned under 3 seconds. Need to say more?
