The 'range' claims made by EV manufacturers are similar to the MPG claims made by conventional gasoline-powered manufacturers: Fantasy.
A little over a year ago, Forbes published an article detailing how the advertised range of EVs was often way off.
...“I’ve been road testing electric cars regularly for more than two years now, and not once has a battery-only vehicle met the claimed capacity for its battery,” wrote senior contributor Neil Winton. “The average shortfall is close to 20%.”......SAE International studied the performance of 21 EV models this year and found that, on average, the cars’ range was inflated by 12.5%. “Most (EVs) tested to date fall short of both their electric consumption and range label values,” the report finds. EVs, it turns out, do worse on long-distance trips than urban short hauls because constant braking helps recharge their batteries...
.
Oh, yes, it's really worse than that!
....Consumer Reports tested how well EVs performed in different weather conditions and “found that cold weather saps about 25% of range when cruising at 70 mph compared with the same conditions in mild weather. In the past, we found that short trips in the cold with frequent stops and the need to reheat the cabin saps 50% of the range.”
For example, Ford’s Mustang Mach-E, which is supposed to get 270 miles on a charge, could manage only 188 miles in the cold. Tesla’s Model Y, which has an official range of 326 miles, went just 186 miles in the cold.
Another report shows that battery performance deteriorates when outside temperatures get above 86 degrees.
Then there’s the fact that carmakers recommend owners charge their cars to only 80% capacity – to extend battery life – which cuts even more deeply into the real-word range of EVs....
Used to be that Disney held the claim to "Fantasyland."
No longer.
