New SAE paper says EVs worse than ICEs at hitting EPA-rated range estimates
Story by Jonathon Ramsey • 3h ago
 
Anecdotally, we probably come across the same number of comments here and elsewhere about how battery-electric vehicles don't achieve their EPA-rated range estimates versus how they do achieve or exceed their range estimates. A new technical paper from the Society of Automotive Engineers (SAE) co-authored by Car and Driver asserts that "most BEVs tested to date fall short of both their electric consumption and range label values." Not only that, the writers say that the disparity between claimed and actual EV driving ranges is wider than the same disparity for vehicles powered by internal combustion engines. Presenting the paper at this week's SAE World Congress Experience that discusses the hurdles facing transportation and mobility, C/D testing director Dave VanderWerp and SAE's Gregory Pannonethe assert the problem isn't with BEVs, but with EPA testing and calculation procedures.
 
The quick backstory is that in 2016, Car and Driver added a highway portion to its fuel economy testing. The route is a 200-mile out-and-back loop on I-94 in Michigan, run with the cruise control set at 75 miles per hour, the speed backed by GPS verification. The mag explained the process in detail in 2020, including how EV testing adds a few extra steps to ensure state-of-charge consistency, measure range fluctuations over time, and extrapolate data points to adjust for last few percent of unused charge. Last October, VanderWerp explained, "We chose 75 mph for our test because driving at a steady elevated speed is the worst range case for an EV (this is not the case for a gas-powered car, which we run at 75 mph to get a highway fuel-economy figure). Another reason is that range matters most in a scenario like a highway road trip where you're driving a lot of miles in a day; nearly every EV on the market has sufficient range when stuck in slow city traffic for hours upon hours."

Fascinating, but it will go right over the head of 99.9% of the voting public.

We are approaching the point of no return, when it comes to investable ROCE on EV's.  Too many feckless GOP and socialist dims are on the train.  It will take some serious disasters and degradation in our lives before they realize it.

I do know, that I am keeping a keen eye on those automakers who plan to continue ICE vehicles for investment opportunies.   They are going to mop up when the consuming pubic revolts.
