Autocar has learned that Mercedes’s AMG performance car division will join the production electric cars with an even more powerful model. According to a senior Mercedes engineer, it will have reserves equal to those of the existing S63 4Matic, which is powered by a 4.0-liter V8 petrol engine with twin turbochargers.

This suggests that the AMG EQS, which is slated to be released in 2022, will achieve well over 600 hp and 663 lb-ft from a twin-engine configuration similar to that used by the most powerful of its standard siblings.

For comparison, the most powerful version of the Model S today, the P100D, develops 784 hp and 841 lb ft.

Nothing is official at this point, but AMG would have signed a modular electric transmission strategy similar to that in place with its more conventional combustion engine models.

The likely scenario, according to a source, is that the next AMG versions of the EQS, the smaller EQE sedan and the eventual electric all-terrain G-Class (which should be dubbed the EQG) will all share the same high transmission. performance, reflecting how the current 63-badge AMG models use a common combustion engine. It is not yet known whether more compact models, such as the EQA and EQB, will benefit in the same way.

According to a manager familiar with Mercedes ‘Electric First’ plans, the AMG transmission was developed in part to meet the looming challenge of Tesla’s ‘Plaid’ transmission. The California-based automaker’s three-engine configuration is shrouded in secrecy, but it is already rumored to develop up to 800 hp and over 1,000 lb-ft.

Volkswagen is also known for working on high performance electric transmissions. The German automaker recently confirmed that it is using the technical know-how acquired in the development of its prototype sports car ID R as the basis for a new transmission for its R performance car division.

As the concept shows, the AMG version of the EQS will send its reserves on the road via a new advanced four-wheel drive system capable of varying the amount of power and torque delivered to each individual wheel.

The new model will have even more powerful acceleration than the standard EQS, which Mercedes says already has the potential to go from 0 to 62 mph in 4.2 seconds. Unlike the current EQC, which is limited to 112 mph, it is also likely to have a high top speed at 155 mph, in line with its performance car positioning.

The power of the EQS motors is supplied by a 100 kWh lithium-ion battery. It is housed in the flat floor and is expected to offer a range of up to 430 miles on the WLTP test cycle, although sources close to Mercedes suggest the actual figure will be closer to 320 miles. Like the Taycan, it will support fast charging of 350 kW – a development that Schäfer says will allow the battery to be charged to 80% of its capacity in 20 minutes.
