THE MOST EFFICIENT CAR EVER CREATED? MERCEDES EQXX

EV Channels Review

The Mercedes EQXX is presented as a groundbreaking vehicle, pushing the boundaries of electric car efficiency. The video highlights Mercedes' ambitious goal of achieving 1,000 kilometers on a 100 kWh battery, targeting an exceptional 10 kWh/100km consumption rate. The reviewer meticulously breaks down the key factors contributing to this efficiency: aerodynamics, weight, rolling resistance, and powertrain. Notably, the EQXX boasts a drag coefficient of 0.17, a frontal area of 2.12 m², and a significantly lighter chassis compared to production EVs. The innovative passive cooling of its battery is discussed, along with its implications for longevity versus charge cycles. The powertrain efficiency of 95% is lauded as near theoretical limits. Ultimately, Mercedes successfully achieved and even surpassed its range and efficiency targets in real-world tests, reaching 8.3 kWh/100km and over 1200 km on a single charge. The video concludes that while further improvements are possible, the theoretical efficiency cap for such vehicles is around 8 kWh/100km, indicating significant but not limitless potential for future EVs.
