I know diesels are best for "long" motorway mileage and hybrids are best for town traffic (and that official MPGs are not realistic), but I can't work out what's best for me. My round trip to and from work is 37 motorway miles and 16 A/B road miles a day half of which is stop start, plus about 10 miles in town travel a week with the occasional 60 mile motorway trip thrown in (about once a month).
I currently drive a bit nun-like in an Auris 1.4 T3 from which I get about 530 miles between fills of about 42 litres diesel (think it works out about 55 mpg). I've been thinking of getting a hybrid Lexus CT 200H (mainly for looks and spec) but reading user reviews, it seems people are happy getting about 50 mpg from this - I would have expected more considering what I get from my car? Then I'm thinking of a hybrid Auris (official combined mpg a bit better than the Lexus but gear changes are awful) or a diesel Peugeot 208.
Can anyone suggest which of these would be best, or make another suggestion based on my usage? (I can only drive automatics btw)
