Vintage Sports Cars That Weren't Really That FastMany sports cars released in the 20th century looked fast, but many were slower than their design suggested.Muscle cars promised power, but their limited technology made them less fast than expected. These vehicles, however, captured the attention of enthusiasts because of their design and the experience of driving a car that seemed destined to win on a racetrack.For example, the Triumph TR7 had an incredible design, but its engine was modest and underpowered, as was the Pontiac Fiero of the 1980s, whose aesthetics led people to believe it had high performance.The following photos show cars idealized by collectors and vintage car enthusiasts, where image is more important than power.20.
