Fiero Specs

[Year By Year Fiero]     [Accel Times]     [Detailed Tech Specs]    


"...the car is beautifully balanced and almost refuses to do anything
but go where you point it. In its tenacious stick and ability to go very
fast over a mountain road with a minimum of driver effort, the Fiero GT
feels more like a smaller, tighter Corvette than a direct competitor to
any of the imported 2-seaters. It feels solid, strong, fast and a little
bigger than it looks. ... It looks racy and exotic, sticks to the road
like glue, sounds good and gets you from one side of the mountains to the
other quicker than all but a few cars on Earth."
