The Mercedes-Benz EQS580 and AMG EQS beat their EPA scores in our 75-mph vary check, a feat solely 5 different EVs have completed.

The 516-hp EQS580 went 10 miles farther than its 340-mile estimate, and the 751-hp AMG EQS went 13 miles farther than its 277-mile estimate.

Many components are at play, however a giant one is that we suspect Mercedes—like different German manufacturers which have performed it—is conservative with its EV vary estimates.

    Welcome to Automobile and Driver’s Testing Hub, the place we zoom in on the check numbers. We have been pushing autos to their limits since 1956 to supply goal information to bolster our subjective impressions (you may see how we check right here).

    It is uncommon that an electrical automobile beats its EPA vary estimate in our 75-mph real-world check. How uncommon? Effectively, we have run vary assessments on greater than 50 EVs so far and to this point solely seven—about 13 %—went farther than marketed. The most recent to hitch this choose firm are the Mercedes-Benz EQS580 and the Mercedes-AMG EQS, which exceeded their mixed EPA figures by 10 and 13 miles, respectively.

    Each Mercedes fashions have an electrical motor powering every axle and a 107.8-kWh battery pack. The 516-hp EQS580 is predicted to journey 340 miles on a full cost, and the 751-hp AMG EQS is predicted to go 277 miles, in accordance with the EPA. For the failed mathematicians on the market, that is a distinction of 63 miles. And, in our highway-range check, we noticed practically that very same hole, the place the EQS580 lined 350 miles and the AMG EQS traveled 290 miles.

    The share of EPA vary achieved by the EQS580 and AMG EQS is 103 and 105 %, respectively, nevertheless it’s notable as a result of so few EVs have performed it since we first began testing freeway vary in 2016. The checklist of different overachievers presently consists of the Audi e-tron Sportback, the Audi e-tron GT (and RS variant), the base-model Porsche Taycan, and the Taycan 4S Cross Turismo. Amongst these, solely the Porsches achieved a better share of their EPA ranges than the Benzes—112 % for the wagon and a powerful 124 % for the sedan.

    What’s noteworthy about that group is all of them come from German manufacturers. What’s equally notable is that the Lucid Air and Tesla Mannequin S are lacking, regardless of the Tesla being the primary to crack 300 miles of real-world vary after a 320-mile end result, and the Lucid being the primary to interrupt the 400-mile mark after masking 410 miles at a gentle 75 mph. The reality is, each the 2022 Lucid Air Grand Touring and 2021 Tesla Mannequin S Lengthy Vary Plus we examined fell woefully wanting their EPA vary estimates. The Lucid missed its 516-mile ranking by 106 miles, which is just 79 % of its EPA estimate. The Tesla missed its 412-mile ranking by 92 miles—solely finishing 78 % of its EPA vary.

    So, what is the distinction between the Germans that outperformed their EPA-rated ranges and the People that did not? Merely put, we suspect the previous group is way more conservative than the latter in relation to estimating how far their respective EVs will go together with full batteries. Particularly with the EQS duo, their 107.8-kWh internet capability is just 3.9 kWh greater than the Mannequin S Lengthy Vary Plus’s (103.9 kWh) and 4.2 kWh lower than the Air Grand Touring’s (112.0 kWh). Nonetheless, Mercedes’s mixed EPA estimate for the EQS580 is a startling 176 miles decrease (about 34 %) than Lucid’s estimate and 72 miles decrease (about 17 %) than Tesla’s. The gaps are even wider between the 2 American fashions and the AMG EQS, however you get the image.

    In fact, different issues performed an element within the Benzes beating their EPA-rated ranges, nevertheless it’s troublesome to quantify every contributing issue. Each fashions are tremendous slippery due to their aerodynamic-focused, cab-forward design that helps ship extremely low drag coefficients of 0.20 for the EQS580 and 0.23 for the AMG EQS.

    Tires even have a huge impact on vary. Whereas our AMG model wore Michelin Pilot Sport EV rubber that is designed for sporty dealing with and low rolling resistance, our EQS580 wore surprisingly aggressive Goodyear Eagle F1 Uneven 5 summer time tires and nonetheless beat its EPA ranking. Maybe there is a technique to squeeze much more vary out of Mercedes’ electrical luxurious barge? Both means, for now, the Benzes are a part of an unique membership of vary beaters.
