Interesting, how ICE release cars bottom up but EV do it top down. GM should have led with the Lyriq.Mercedes has announced some of the specs for the EQS AMG 53. It will have 649 hp, with 751 hp on tap with a Boost Mode (similar to the Tesla Plaid Launch Mode and the Lucid Air Dream Sprint Mode). Mercedes is claiming 0-62 in 3.4 seconds (about 3.2 for 0-60). No information has been released on range or pricing.
In its ICE lineup Mercedes has sometimes offered both an AMG 5X and an AMG 6X version (such as the S53 and the S63 or the old SL55 and SL65). So maybe Mercedes is leaving the door open for a more powerful EQS AMG variant further down the road? It's certainly going to need to if it hopes to become a performance contender against Tesla and Lucid.
