A smaller list of two cars that are historically significant and should be included to the GT family of cars.
If the way to go is the EV way then I believe this next car should be added for it's contribution to the start of modern EVs...
The General Motors EV1 is a battery electric car produced by the American automaker General Motors from 1996 until its demise in 1999.
A subcompact car, the EV1 marked the introduction of mass produced and purpose-built battery electric vehicles.[2][3] The conception of the EV1 dates back to 1990 when GM introduced the battery electric "Impact" prototype, upon which the design of the production EV1 was largely inspired. The California Air Resources Board enacted a mandate in 1990, stating that the seven leading automakers marketing vehicles in the United States must produce and sell zero-emissions vehicles to maintain access to the California market.
Mass production commenced in 1996. In its initial stages of production, most of them were leased to consumers in California, Arizona, and Georgia. Within a year of the EV1's release, leasing programs were also launched in various other American states. In 1998 GM unveiled a series of adaptations for the EV1, encompassing a series hybrid, a parallel hybrid, a compressed natural gas variant, as well as a four-door model, all of which served as prototypes for possible potential future models. Despite favorable customer reception, GM believed that electric cars occupied an unprofitable niche of the automobile market. The company ultimately crushed most of the cars, and in 2001 GM terminated the EV1 program, disregarding protests from customers.
This next car should be added for its premise of alternative powerplants for road cars...
The Chrysler Turbine Car is an experimental two-door hardtop coupe powered by a turbine engine and was manufactured by Chrysler from 1963 to 1964. Italian design studio Carrozzeria Ghia constructed the bodywork, and Chrysler completed the final assembly in Detroit.
A total of 55 cars were manufactured: five prototypes and a limited run of fifty cars for a public user program. All have a signature metallic paint named "turbine bronze", roughly the color of root beer. The car was styled by Elwood Engel and Chrysler studios. They featured power brakes, power steering, and a TorqueFlite transmission.
The Chrysler turbine engine program that produced the Turbine Car began during the late 1930s and created prototypes that completed long-distance trips in the 1950s and early 1960s. The A-831 engines that powered the Ghia-designed Turbine Car could operate on many fuels, required less maintenance, and lasted longer than conventional piston engines. However, they were much more expensive to produce.
After testing, Chrysler conducted a user program from October 1963 to January 1966 that involved 203 drivers in 133 cities in the United States cumulatively driving more than one million miles (1.6 million km). The program helped the company determine problems with the cars, notably with their complicated starting procedure, relatively unimpressive acceleration, and sub-par fuel economy and noise. The experience also revealed the advantages of the turbine engines, including their remarkable durability, smooth operation, and relatively modest maintenance requirements.
After the user program ended in 1966, Chrysler reclaimed the cars and destroyed all but nine; Chrysler kept two cars, six are displayed at museums in the United States, and one is in comedian Jay Leno's private collection. Chrysler's turbine engine program ended in 1979, mainly due to the failure of the engines to meet government emissions regulations, relatively poor fuel economy, and as a condition of receiving a government loan in 1979.
