According to Carnegie Mellon University electric vehicle researchers Shashank Sripad and Venkat Viswanathan, who track the relative efficiencies of various electric powertrains and have been analyzing the Lucid Air over the past several weeks, the new car scores 218 watt-hours per mile in overall efficiency—factoring in the car’s stated range, weight, drag, frontal area, and rolling resistance—while the Tesla Model S requires 250. (The lower the number, the less energy the car consumes with each mile.) “So far most of the new EVs unveiled were not able to achieve the powertrain efficiency of Tesla,” Sripad says. “All of the previous EVs needed much bigger battery packs to achieve similar ranges because of their lower powertrain efficiencies. This car breaks the trend that all the new EVs faced when being compared to Tesla.”
