Potentially, but bit late now I've sold it! There was mpg on the table with the tyres too, but the biggest problem is inherent to the car, it's just wildly aerodynamically inefficient. I suspect someone living in say, the Netherlands where it's mostly flat and speeds away from highways are pretty low would get way better figures, but in the UK you're always fighting hills and air resistance.

The Insight is just much better in most like-for-like scenarios. It's hugely more aerodynamic and has more power in reserve when conditions are suboptimal, such as punching against headwinds or climbing hills.

(Edit: In case you missed it, those figures were US mpg, so it was averaging 72mpg in imperial gallons - looking at Fuelly, where there are a lot more of these things than on EM, my 60mpg US/72 UK is higher than the majority of similar cars on there)

It's an automated manual, yeah - semi-auto was just my shorthand for that.
