Not sure what the mpg was in the review above for the Nissan e-power, but the one I watched a couple of weeks ago, it was about 35mpg which didn’t seem very good if comparing to a Hybrid Sportage/Tucson. But if comparing to a Sportage/Tucson MHEV, then it’s quite good.
I think a lot of this new engine technology is helping the short journey mpg, but makes no difference to long runs, especially with the extra weight involved.
