Mitsubishi Wants to Publish Real World MPG Figures on its Cars


2012 Mitsubishi Mirage

Automakers like Ford, Hyundai, and Kia have been under fire recently for selling cars that fail to deliver on the fuel economy promised by their EPA MPG ratings. In a bid to distance itself from those automakers finding themselves in hot water with their customers, Mitsubishi is planning to be more open with its customers about what kind of fuel economy its models can achieve in real world driving.

The plan is to start with the company’s upcoming Mitsubishi Outlander PHEV, which carries a “claimed” 140+ MPG rating. Mitsubishi’s UK director, Lance Bradley, explains that hybrids often don’t perform as well as advertised in terms of real world MPG, making setting expectations for Mitsubishi’s high-profile PHEV launch critical. “Customers came back saying it only did 90 MPG. It’s crazy (to think) that’s bad, but it’s all relative to the official figure,” he explains. “We’d like to do a graph, maybe just a figure, starting with the PHEV but then rolling it out to other cars. It would come from customer information,” said Bradley, suggesting that early adopters or auto journalists could input their real world MPG to make it clear to prospective owners what they should expect.

If the move is embraced by Mitsubishi customers, expect to see real world MPG stickers start to appear on cars like the Outlander Sport (which I loved, when I got to drive it) and the Mirage CVT (the highest EPA rated MPG car in the US that’s not a hybrid) sometime next year.

  • They should publish the entire range of MPG that different people get, and the mean number, too.

    Just driving a car any old way (like a bat out of hell!) means that you may or may not be similar to the published number. Giving the range will *encourage* people to try do well.

    Ecodriving is a learned skill.

      One of the things that helped me learn ecodriving was a rented Kia Forté. It has a little “Eco” light — just an idiot light — but I had fun accelerating slowly to keep the light illuminated.

      I then took that knowledge to my (at the time) ICE vehicle and got significantly better gas mileage.

      Now that I drive an i-MiEV, its power gauge helps me drive more efficiently too. There is no reason ICE vehicles couldn’t also have a similar power gauge (without the “charge” part, of course).

      • Better yet, every ICE car should have both an ‘instant’ MPG and an average MPG gauge. If these are one above the other – the instant on top and the average below, then you try to keep the instant number higher than the average, and you will continue to improve the average.

    How about saying things like “your mileage results may vary”. I remember car advertisements saying things like that.

    • I’m pretty sure they say that still – but that is fine print and most people ignore it, or don’t really stop to think what it means.

    • Jason Carpp

      And not many people read the “fine print.” Perhaps they should make it so that it’s easier to read.
