> We've never owned a gas vehicle that met it's EPA range and the Tesla is no different. No one takes EPA MPG * GALLONS of gas and expects it to be a real life estimate of range.

Why is this exactly? It's been true - MPG is lower than estimated - of every vehicle I've owned too except for my most recent, a '23 MX-5 (i.e. a sports car, which I tend to drive at higher RPMs and in lower gears.) I'm getting spot-on or a little above the EPA estimated on the car I'd least expect it.

(edited to clarify "it's been true")




There's an EPA website for this.

https://www.fueleconomy.gov/feg/browseList.jsp

I have a 10 year old Mazda 3 and the MPG estimate is on target: 32 combined 28 city 39 highway estimate and I get 36 mpg. User average is 35.2.


Consider yourself lucky. Off the top of my head both Ford and Subaru were subject to lawsuits about vehicles not meeting EPA range expectations. When I had an outback I was very lucky to get 17MPG and the EPA range on the window sticker was 27 which felt really deceptive.


FWIW, one of my vehicles which _does not_ get the EPA estimated is a 2017 Ford Fusion 2.0L AWD. EPA estimate is 20/29/23 (city/highway/combined.)

I normally get 21mpg combined, which is really not so far off. Lots of highway driving usually gets the average up to 23.5mpg. With that worst-case number, across a full tank of gas (16.5 gallons x 2 mpg), I'm shorted about 33 miles, or 8%.

Is that pretty comparable to what Tesla users see? The article claims it's much higher:

> Tesla was fined earlier this year by South Korean regulators who found the cars delivered as little as half their advertised range in cold weather. Another recent study found that three Tesla models averaged 26% below their advertised ranges.


27 hwy? My 2013 STI gets like 23/19 on a good day and requires 93 oct or higher. oof!

My fuel efficiency is horrid and advertised to be horrid.


I’m surprised you’re getting such good economy. I was getting 13mpg in my 2013 in stop and go traffic. Which is all I drove in at the time, and a contributing factor in selling it.


I think the EPA estimate for highway is based upon a totally flat windless road at 55 mph
