The Fiero was created in response to the MR-2 and (arguably) the CRX. The CRX being unarguably the superior execution, since the front engine design left room for a usable hatch, and an aluminum 109hp 4-banger really wasn't enough to overload the front wheels.
The Fiero was a noble effort. Being mid-engined, they could afford to throw more displacement at the problem. Unfortunately, engine tech and emissions restrictions in the 80s meant that the "big" V6 was a wheezy, underpowered piece of shit.
If they tried to recreate the CRX today (mention CR-Z and I'll cut you), it would be a disaster. Cars are too heavy, so it would either be underpowered, or if they put a sufficient powerplant into it, it would be too front-heavy and succumb to the perils of FWD.
However, if anyone tried to recreate the Fiero , they'd have an aluminum 300hp V6 at their disposal. And I'm not just talking GM. Everyone has an aluminum 300hp V6 that would put an NSX to shame. They're all derived from boring sedan motors bred for durability, they're all being produced in massive numbers, and they'd all be perfect in the middle of a 2800 lb coupe.
OTOH, no automaker currently has a cheap mid-engine platform, and with the death of the last MR-2, I can't see anyone resurrecting one. I feel like we've finally got a dearth of great V6 engines, and crash test standards and economics of scale mean we'll never put them in anything awesome.
Any rebuttal?
