MPGe is the complete opposite of a useful number. MPG itself is already a misleading metric. The relative value of each mile improvement declines exponentially as MPG rises. An improvement from 10 to 11 MPG, saves the same fuel as an improvement from 16.5 to 20, or from 33 to 50 MPG. Low MPG vehicles e85 gas stations colorado use substantially more fuel than high MPG vehicles. MPG is bad enough as a metric, but MPGe makes it worse by confusing electricity usage with petroleum usage under the guise of an efficiency measure. Most of the social reasons we care about efficiency in petroleum-fueled vehicles simply do not exist for electrically-driven vehicles or exist at massively lower levels. For petroleum combustion vehicles, increased efficiency directly reduces emissions responsible for increased health costs and death. It reduces the economic and political influence of foreign powers. It reduces capital outflows. Fuel economy requirements associated with MPG were created to address these many social issues. These issues are generally much lower or non-existent for electrically driven gas efficient cars under 5000 products. Virtually the only reason to care about efficiency in an EV powered by wind, solar, hydro or sustainable biofuels is the vehicle’s usability. And the mere existence of the EV … Read more »

“so the model 3 is more efficient than the ‘s’, right?” Sure. It’s a smaller car, with about equally aggressive streamlining and similar acceleration, so naturally the TM3 uses few kWh per mile. “I thought I had read here the S was particularly inefficient at least compared to the bolt or maybe the wb state electricity board bill pay leaf?” You can unfortunately read a lot of Tesla bashing FUD from a few serial Tesla bashers here. Here are the facts, per the U.S. Dept. of Energy’s website (link below): The 2017 Tesla Model S AWD – 90D is rated by the EPA at 32 kWh/100 miles, vs. the 2017 Nissan Leaf at 30 kWh/100 miles. (The “P” performance versions of the Model S are less efficient… which is also expected.) For the much heavier and much more powerful Model S, that surprisingly small difference in efficiency strongly indicates superior engineering as compared to the Leaf. And no, it has almost nothing to do with permanent magnet motors vs. induction motors. That’s a trivial difference, and has more to do with cost electricity symbols than efficiency. Tesla was using induction motors because permanent magnets were quite expensive, but now that a way has been found to make those … Read more »

40% more power, 40% more range, vastly improved styling, and AutoPilot rivaling driver assistance is “lipstick” to you? I’d say so. “vastly improved styling” is the definition of a cosmetic, “lipstick” improvement. So it got a face lift, so what? 40% more battery is very nice, but given the SEVEN year gap between the first leaf and this one and the dramatic progress made in the EV industry during that time, a battery with less than twice the range of the original is, yes, “lipstick”. It’s way below the industry leaders long after they already started gas turbine shipping. And worse, no other efficiency improvement at a time when competitors are doing so much more – the same efficiency, just bigger. They didn’t even improve the weight ratio, just added more of the same battery that is now hopelessly uncompetitive. “auto pilot” is basically trying to distract from the fact that they have done NOTHING to the electrical side of the car except add more of the same old technology battery. If you are buying a car for this technology, well great. But if you are buying for an EV the LEAF is the last choice anyone should consider, especially after their … Read more »

“Worrying about, or even talking about this efficiency electricity generation efficiency number is a seriously ‘inside baseball’ thing for us to be indulging in. Have you talked to non-plugheads about the chances they’ll buy an EV?” Okay, but InsideEVs isn’t just a place for proselytizing to gasmobile drivers; it’s also a place for EV advocates to share info and ideas, and discuss issues. Tesla is now ignoring the whole issue of watts and kWh in its advertising, simplifying things to just talk about range and charging time. That may tropico 5 electricity be the best approach. But as soon as someone buys an EV, then he’s going to need more info. There are a lot of posts on the still relatively new InsideEVs Forum from new EV owners who suddenly want to know all about kWh and battery pack capacity and charging rates and other sorts of technical issues. I think the best advice here is “Begin as you mean to go on.” We shouldn’t have one set of measuring standards for people who know little about EVs, and another set of measuring standards for “inside baseball” discussions of EV technical issues. People should already know what a kilowatt-hour is from their electrical bill, and explaining … Read more »
