Supposedly, the MX-3 had a Cd of .32 and .31 in GS trim.
For comparison, the '92-95 Civic hatch had a stock Cd of .31 ( While oddly enough, the Civic coupe had a higher Cd of .32 )
I have seen the MX-3 Cd figures elsewhere and think these quoted on this site are legit, but I have my doubts about the mileage figures listed.
( I notice that the site is Canadian and was wondering if the Canadian version of the MX-3 did indeed get better mileage. )
Is it a Canadian thing Metro ??
