I always got poor fuel economy can be
compared to the Viper with less than
half the horsepower. Got the a rebuilt
engine and it did not improve much.
problem is that Mazda is trying to use
a sweep seal(seal at bottom of your
entrance storm door) to follow a rather
complicated architecture. Anyway when
the mechanic changed the coolant he did
not fill the radiator properly. The
engine overheated & the seals went.
After this I did not put more effort
into the car and bought a Chev Camaro
which I am pleased with.
Body design. Body and chasis built
around engine. Higher engine revs.
Use of better seals such as those use
in high performance windows and
entrance doors that can also withstand
higher tempuratures. This should
improve the efficiency of the engine.
