Consulier GTP Series I
A Florida builder tried to make speed from low mass, wrapping a familiar turbocharged Chrysler engine in an unfamiliar composite structure.

Research pending
A matching completed auction sale has not been verified for this exact year, body, trim, engine, transmission and market.
Joyride shows this gap instead of substituting an asking price, unsold bid or mismatched special vehicle.
More than a set of wheels.
Investment manager Warren Mosler conceived the GTP in the mid-1980s and Consulier developed it in Riviera Beach, Florida. A contemporary MotorWeek test aired in June 1989, while a later federal notice records the transition from development to the first handful of production cars that year. This profile stops at the original Turbo II Series I; the more powerful Turbo III Series II and later Mosler Intruder and Raptor are different evolutions.
Look a little closer.
The gearbox was related to the Getrag-built five-speed used with Chrysler's turbocharged Shelby models, a practical donor part inside an otherwise unusual car.

Composite was structure, not just decoration
The GTP combined a fiberglass-and-foam monocoque with carbon-fibre and Kevlar body material. This was not merely a thin cosmetic skin over a conventional steel passenger shell. Reducing structural mass was the central idea: the modestly sized Chrysler engine could produce strong performance because it did not have to accelerate the weight of a typical contemporary grand tourer.

Retrospectives give several starting years because prototypes and race development preceded sale. The federal record provides a firmer boundary: Consulier described the project as research and development through June 30, 1989, then reported four production cars before September 1 and a fifth afterward. That evidence supports 1989 for the initial production Series I without relabelling every earlier prototype as a customer car.
