EV scope ratings are wished by nan EPA pursuing a standardized trial connected a dynamometer that simulates urban, highway, and steady-state driving conditions successful nan United States. It's not a cleanable science, though, arsenic immoderate EVs under-deliver connected their EPA scope while others overperform. A Lucid Air Grand Touring precocious set nan world record for longest EV travel connected a azygous complaint astatine a bladder-busting 749 miles, but a situation arises erstwhile you return a roadworthy travel and nan immense mostly of nan miles you screen are driven connected wide unfastened freeways astatine precocious speeds. This is nan slightest businesslike measurement to thrust an electrical vehicle, since sustained precocious speeds taxable a conveyance to important aerodynamic drag, and unless you deed a postulation jam there's little-to-no opportunity for an EV to recuperate power done regenerative braking. Car and Driver conducted a test to find really precisely precocious speeds impact EV range, and arsenic it turns retired there's a important effect connected scope nan faster you drive.
In bid to execute these findings, Car and Driver drove 2 EVs and 1 gas-powered car astir nan 4.7-mile oval trial way astatine Stellantis' Chelsea Proving Grounds astatine 4 velocity intervals — 35 mph, 55 mph, 75 mph, and 95 mph — and utilized each vehicle's in-car telematics to cipher their maximum cruising scope astatine each speed. The 2 EVs successful nan trial were a Lucid Air Pure sedan and a Kia EV9, while a Subaru Forester carried nan torch for soul combustion vehicles.
The findings

Lucid
The mixed EPA maximum scope estimates are issued pursuing a laboratory trial cycle, truthful real-world scope will alteration greatly. The EPA does rumor a dedicated road scope estimate for EVs, but nan number that gets nan astir publicity is nan mixed estimate. Car and Driver took a look astatine nan EPA-issued maximum road scope estimates for nan Air and EV9, and utilized information from this trial to find nan mean velocity that each conveyance would person to recreation successful bid to execute nan maximum range. In bid to scope its EPA-issued 410-mile road range, nan Lucid would request to beryllium walking astatine an mean of 49 mph. The Kia's EPA-issued road scope estimate is 253 miles, and based connected this trial it would person to person an mean velocity of 71 mph, which is much realistic than nan Lucid's rating.
The Subaru knowledgeable overmuch higher scope degradation arsenic speeds increased, but its maximum cruising scope was higher than nan EVs to statesman with, truthful it had a cruising scope of astir 500 miles astatine 75 mph, down astir 200 miles compared to its maximum scope astatine 55 mph. That alteration is much important than either of nan EVs, but since its cruising scope is truthful overmuch higher it's little of a concern.
While nan electrical vehicles successful this trial took important hits to their maximum ranges astatine precocious speeds, their ranges are still overmuch higher than EVs from conscionable a fewer years ago. There are an infinite number of variables successful nan existent world that effect EV scope arsenic good arsenic nan substance ratio of soul combustion vehicles, but sloppy of really you look astatine it, electrical cars person travel a agelong measurement successful a comparatively short clip span.
