I have not been able to find a measure of the Lightning's MPGe. There's a post on this site that has MPGe in the title, but nothing in the actual post that gives it. I was discussing the truck with a friend and realized that while we have a ballpark for the range, I couldn't come up with the efficiency numbers. Thanks!

That's correct. The MPGe will not be measured until Ford starts testing the pre-production prototypes, which they haven't started building yet.

For the Mustang Mach E, EPA ratings came out about the same time as customer production began, November 2020.

Thanks, Marlin. I thought we were well past that point, as I've seen video of pre-production prototypes in the wild (

shows six at a California Electrify America site) and had this quote from Ford back in September: “One year after Ford confirmed construction of the Rouge Electric Vehicle Center in Dearborn, Mich., the first Ford F-150 Lightning pre-production units begin leaving the factory; the all-electric F-150 Lightning goes on sale next spring.”

Nope. Those are the early, hand-built prototypes. As discussed in another thread, the assembly line i just reached phase 2 builds. They won’t be making pre-production (assembly line) pro types for a few months.

@verbwashington 85-mpg is what this one source is estimating it will be.

Plug In or Gas Up? Why Driving on Electricity is Better than Gasoline

Electricity power plant emissions data and the latest assessments of fuel emissions and vehicle efficiency show 97 percent of people in the US live where driving an EV would produce fewer emissions than a 50 mpg gasoline car.

blog.ucsusa.org

"The official efficiency data is not yet available, but based on the range and charging performance information released by Ford, we estimate the efficiency to likely be between 0.46 to 0.50 kWh per mile. That would make it one of the least efficient EVs available. However, the average gasoline F-150 model is also inefficient for a gasoline vehicle, with a fuel economy rating around 20 mpg. The Ford F-150 Lightning will produce fewer emissions than the gasoline-powered F-150 while driving, even on the dirtiest electric grids in the US. And on the cleanest grids, the electric pickup will likely be responsible for less than a quarter of the global warming emissions of the gasoline truck. For example, in California, driving the F-150 Lightning should produce global warming emissions equal to an 85 mpg gasoline vehicle, better than any gasoline car or truck. For over 70 percent of the population in the US, driving the electric version of this vehicle should produce less than half the global warming emissions of the gasoline model."

Thanks, that's a useful article in many ways. I can live with 85 MPGe!

Likewise, I can get by on less but of course more is better. I have high hope in Ford's battery tech, especially after listening to what Sandy Munro had to say about what they're capable of.

This article is comparing the carbon footprint which shouldn't be confused with MPGe.

 

[Eclectic]

Will the instantaneous MPGe be visible on the display?

 

[ChasingCoral]

Probably not. It’s not a very useful metric. The display provides miles per kilowatt-hour. Miles/kWh is the equivalent to mpg.

 

[Prof1ig8tor]

Actually, an emissions equivalent is not MPGe. It is assumed the US grid is about 60% fossil fuel powered (in most these comparisons) MPGe is a measure of energy use, not emissions. More accurate measures would be in kilowatts / mile.

The Rivian R1T is around 70 MPGe. My Tesla M3 is about 135 MPGe. I am expecting the Lightning standard battery to be slightly better than the Rivian and the max battery to be slightly worse.

There is a whole lot we do not yet know about the Lightning. Does it have a heat pump? Is the design limited by the abilities of suppliers who are not yet building efficient HVAC systems? How is thermal management of the battery handled?

The spice in Tesla’s secret sauce is that they in source and build all their own sub systems. Tesla has a heat pump which replaced inductive heating. Tesla has little cooling lines and has even optimized their in car chip boards to use very little power (self driving system is less than 100 watts for two redundant systems, yet it has about 7x the video processing power of a gaming PC which are 700 plus watts these days) All of this adds up to a 25 to 30% more efficient vehicle which is then easier to charge, uses a smaller battery, is lighter and goes further.

Ford may very well have come a long way from the Mach E. We just don’t know yet…. Lucid hit it out of the park on their first product. The Rivian’s inefficiency surprised me (many blame the tires). Ford has done a lot of aero work with the truck and the aluminum body may make this a great EV. We will just have to see.

Yes, sorta.

It is in KWH/Mile
