2 cylinder turbo'd "boxer" engine would be lots of fun, it would idle like a dam tractor but does that matter when your pulling 60mpg out of it??
as for tourque im impressed its almost half of what my 1.2L motor produces (300nm of pushrod power)
,
acceleration would be "snappy" on it but i do believe that it would struggle moving 2 people, especially if it is a 4 stroke
