Ultra effecient combustion cars, under 1.5 litre, thoughts, pics, comments, designs, concepts Options

Given todays economic climate, possible scaricity of fuel, and of course just the raw challenge of building a car with high mpg,
we should have a thread on cars of this nature, in production,prototypes,homebuilts, concepts and pictures.
( I wish i had the time and energy to build a car with a sub 1 litre engine, and maybe one day i will)

but lets keep it to combustion power, for now

FWIW, my commute car is a 2009 Honda Fit Sport, with the paddle-shift AT. It replaced my '98 M3, which while enjoyable, was the most expensive car to maintain I've ever owned, used premium fuel, and got about 19 mpg on my commute. I replaced the skinny OEM tires with 205/50's, which helped handling and braking. It's a really fun car, I can drive it flat-out with barely anyone noticing, and still get 30 mpg on my commute. On flat highway drives it gets 40+ mpg. Extremely practical, gobs of front and rear seating room, fold-flat rear seats for a huge cargo area. Full of safety features, too. 5-star crash ratings, airbags galore, seatbelt tighteners, and active front headrests. It's also reasonably cute looking and fun to drive. 100K miles before the first tune-up, too.
