Ecoboost is Ford's name for using smaller displacement turbo engines to replace larger naturally aspirated ones. My experience with these types of cars is that with typical real drivers they do not deliver anywhere near the EPA fuel economy numbers, because they're essentially designed to make the turbo never spool up in the EPA tests. You can get the EPA numbers if you drive very slowly though.
- rjsw 9y agoI have a 1.6 EcoBoost Mondeo, it gets pretty close to the published economy numbers and I don't drive particularly slowly.
- opencl 9y agoThe Mondeo is apparently the UK version of what's known as the Fusion in the US, maybe the UK has more accurate fuel economy testing than the US. Or everyone I know who complains about not getting EPA numbers just has a lead foot.
- userbinator 9y agoI recall the summary phrase from an article about Ecoboost a while ago: "You can have Eco, or Boost, but not both." It's possible to get better fuel economy with a larger engine than a smaller one, since the larger one won't need to be flogged a lot to get the needed power. The old American cars with big V8s could get surprisingly high (20+mpg) mileage this way. Of course, the trick with a big powerful engine is to resist the temptation to use all that power all the time. ;-)
