Kick the Prius, get a Mini
diesel version of the new new mini will be kicked in august...
...for a new diesel version, allowing to do 72.4 mpg and just 104g co2 (64.2mpg & 118g before). the same as the prius. it'll have start-stop automatic like its big brother the 1series beemer and it'll show you on a display, when it's time to change gear in the most economical moment.
but don't be afraid it won't look different again, so it's no new new new mini 
.
btw #1: why do some people here don't like the new new mini?
btw #2: which gallon is in "miles per gallon"? the imperial gallon or the US liquid gallon?
