Japanese firm wants to be more open with customers about achievable economy figures

Mitsubishi is planning to be more open with its customers about what kind of fuel economy its models can achieve in the real world, according to UK MD of Mitusbishi, Lance Bradley.

It would start with the new Outlander PHEV (plug-in hybrid electric vehicle), which claims 148mpg, since hybrids often perform deceptively well during official testing. Bradley tells us that in the real world, though, “customers came back saying it only did 90mpg. It’s crazy that people think that’s bad, but it’s all relative to the official figure.”

“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 buyers could input their real world fuel economy to make it clear to prospective owners what they should expect.

It’ll be an important next step for Mitsubishi considering it is planning to have every single one of its models offered as a plug-in hybrid electric variant in five years’ time. The next-generation ASX for example will get a less complicated PHEV system than the Outlander, making it front-wheel drive only. That’ll be followed by a PHEV Shogun and Mitsubishi is planning another small all-electric car, too.

This will be interesting because I can guarantee that I can better the government figures published for any car.

I would actually love all auto manufacturers to do this, especially the VW Group who always seem to tweak and play the testing system.

A nice graph viewable to the public taken from the trip computer averaged out would be so welcome. Plus little bits of information such as what road it was driven on, what
was the outside temperature at the time, what revs did the driver
normally change gear and so forth would go a LONG way to showing actual
figures from an actual human behind the wheel

Well done Mitsubishi!

This policy is no doubt to avoid the "C-Max Syndrome" whereby Ford obscured the benefits of its C-Max Hybrid by saddling it with an overstated EPA rating derived from the Fusion Hybrid, a more aerodynamic car. The C-Max is a lovely 43 MPG car. It's a lousy 47 MPG car.

Current figures work fine as a basis for all manufacturer's to be compared side by side under the same conditions. Sadly the public views these figures and expects them in the real world of Aero drag, interference drag , heating and airconditioning etc. It is up to car mags to do real side by side reviews to give real world figures and that includes EVs kWh/100km and emissions based on UK grid CO2.
