This isn't your grandad's Mercedes sedan.
To hear the brand tell it, the EQXX was born out of a desire to design the most efficient Mercedes of all time. And if the specs prove accurate, the marque may have done just that. If the EQXX were to go into production today, it would easily be the longest range EV on the market, besting the current title holder, the, by more than 100 miles. The car will also use just 10 kWh of energy per 62 miles, according to Mercedes.
Of course, it should be noted that the EQXX’s range hasn’t been certified by the EPA or reached under Europe’s more-forgiving WLTP test cycle. Instead, it is based on “internal digital simulations in real-life traffic conditions,” according to the brand.The EQXX can achieve its range feat thanks to an all-new powertrain that can produce 201 hp.
Technical details are relatively scarce, but at the heart of the single-motor setup is an ultra-dense nearly 100 kWh battery pack that is 50 percent smaller and 30 percent lighter than the pack that powers the brand’s current flagship EV, the. It’s aided by an innovative thermal management system that only kicks in when needed. This “cooling-on-demand” approach significantly reduces cooling drag.
