We will have a panel discussion with many distinguished members of the original Fiero design, engineering, and manufaturing teams. Bring those questions you have always wanted to ask of the people who were there back in the day. Guests to be announced at a later date as schedules are finalized.
The general public has always known the Fiero as a 2 seater automobile, but those who have been around the Fiero community for the longterm know that there was one exception to this perception - the 2 + 2 Concept Car. GM modified one of the original 1984 pilot cars to study the impact of stretching the space frame. The 2 + 2 evokes the feeling of a Fastback with a little extra room. This silver car contains a custom luxury interior and the drivetrain includes a pre-production 2.8 liter v6. The car was never planned as a possible prodcution model, but was a study in using the space frame technology with larger vehicles. The rear seat is likely one of the smallest back seat spaces ever placed in a GM vehicle making it suitable only for small children and pets.
This car is #25 of the 31 Pilot Build MY1988 built in the second week of March 1987. It has the factory EHPS. The 16,128 miles were accumulated at Milford Proving Grounds. The car was also a test car for the proposed dash and instrument cluster for the MY1990. It is claimed that the car remained at Milford for further development of the instrument cluster for use in the production 1993 Firebird. In 1991, the engineer responsible for the car drove the car home regularly and suddenly passed away. His parents sold the car after storage all these years. The deceased engineer's brother confirmed the story about the cars time at Milford as he still works there and is part of the team that is building some of GM's wicked high performance stuff. There are engineering stickers all over the car including the all important "non-compliance" DOT emissions and safety waiver stuck on the back of the decklid.
One of the three cars prepared by John Callies for the 1984 Indianapolis 500 contains a race-prepared Super Duty 4 cylinder motor with a heavy-duty, race-prepared Getrag transmission. This 2.7L motor reached 300hp and inspired the production of 2000 Indy Fiero Replicas which contained a lesser horsepower, Iron Duke engine. The car was later rebodied for use as a pace car for the Indy Car World Series. After it was retired, it was on display for a number of years at the Chicago Museum of Science and Industry.
Autostyle Plastics was called upon to modify 6 Fieros to serve as vehicles in PPG Industries' Precision Driving Team exhibitions. Renamed Fiero GTPs, these 6 cars were painted in PPG pearl metallic colors to be driven in pre-race demonstrations during the 1986 and '87 Indy Car racing seasons, the latter largely in Europe. Female drivers performed a variety of different stunts and maneuvers to highlight the products and relationships of GM, PPG and Autostyle Plastics. In addition to cosmetic upgrades performed on the interior and exterior of the vehicles, a variety of mechanical upgrades also occurred including the installation of a 3.0L V6 block, bigger lift cam with modified duration that compliments a custom intake. The engines also contain flat-top pistons and reinforced connecting rods that pair with a stock crankshaft and large oil return galleys.
2 of the 6 cars (red and yellow) were ultimately donated to vocational schools while a third (blue) was retained by General Motors for their collection, where it remained until its sale in 2009. The remaining 3 original PPG cars were crushed. All 3 of the surviving cars will be on display at the 35th Anniversary Show.
This unique special project by GM contained a 2.7L Super Duty 4 cylinder. The SD4 is an early cast block that was later upgraded from a cast iron head to an aluminum head. It has a custom fabricated header with no cat, stock exhaust. and 5-speed manual transmission. The car also has electro-hydraulic brakes and electo-hydraulic power steering. Its body styling featured IMSA-style wide body panels and the whaletail spoiler on the frame of a production 86GT. Despite its racing look, the car was fitted with features such as air conditioning, cruise control, power windows and a stock stereo. To date, the purpose of this car build by GM is unknown. It contains 6,902 miles on the odometer.
GM Goodwrench sponsored Fiero. Designed by Pontiac Racing / Engineering, built by Huffaker Racing. Raced from 1984-1991 in the GTU, T/A, and GTO classes. Driven by Bob Earl, Terry Visger, and Dominic Dobson.
