> It's hilarious to me that 34mpg is considered remarkably good, though

I was curious too, I have a manual, petrol engine, Citroën C4 Picasso (called a minivan in English I think? but then I didn't think a Golf GTI was called a minivan so I'm not sure) from 2011 that's not hybrid at all and that's about what I get (7 L/100 km). It's comfortable to be in but not interesting to drive at all though.

I get a very consistent 4,3 L/100 km (54 mpg) on my diesel C4 (basically the same size as a Golf GTI) from 2013 and I like driving this one.

edit now that I've read the sibling comment, Google uses US gallons for its conversions and that's what I've used here.
