Back in 2016, Mercedes-Benz introduced EQ, a sub-brand that would handle its electric car lineup. The German firm has already introduced the EQC crossover and EQV van and it plans four more models until 2022.

One of them is the EQS. Previewed by the Vision EQS concept, the EQS will become the brand's flagship model, essentially an all-electric S-Class with sleeker styling. Confirmed for 2021, the EQS will also spawn an AMG version that's said to be just as hot as the Mercedes-AMG S63.

The base Mercedes-Benz EQS will have close to 500 horsepower

Although it's part of a larger brand that will eventually include 10 models, the EQS will mark a premier for the company: it will be the first model based on Mercedes' dedicated modular electric architecture.

This means that it could be entirely different than the EQC. The same platform will be used in the EQE, which is scheduled to arrive sometime in 2022.

The sedan is expected to hit 60 mph in less than five seconds thanks to a smart AWD system and excellent aerodynamics.

The Mercedes-AMG EQS will boast in excess of 600 horsepower

But Mercedes-Benz will take the EQS' performance to a whole new level with an AMG model that will arrive for the 2022 model year. According to a report by Autocar, the Mercedes-AMG EQS will feature a pair of beefed-up electric motors that will generated in excess of 600 horsepower and 663 pound-feet of twist.

This setup will enable the EQS to go against the range-topping version of the Tesla Model S, which comes with 784 horses and 841 pound-feet on tap. AMG is also said to be working on a rival for Tesla's upcoming Plaid drivetrain, a tri-motor layout rumored to develop around 800 horsepower and 1,000 pound-feet of twist.

When it hits the market, the Mercedes-AMG EQS will probably become the most powerful full-size sedan in Mercedes' lineup. For the time being, this award goes to the Mercedes-AMG S65, powered by a 6.0-liter V-12 that churns out 621 horsepower and 738 pound-feet of twist.

The most powerful V-8 version, the AMG S63, generates 577 horses and 664 pound-feet of twist, but output will increase slightly with the redesign.

The Mercedes-AMG EQS will feature unique styling elements

Just like AMG versions of the S-Class, the beefed-up EQS will stand out thanks to a number of unique features. Mercedes will probably go with a sportier front bumper, a slightly different, but still closed-off front grille, and a diffuser-type element in the rear.
