Pontiac Banshee

The Pontiac Banshee is a line of concept cars designed by Pontiac. Beginning in 1964 they assumed the role previously established by General Motors' Firebirds of the 1950s. Four Banshee "dream cars" were fabricated through 1988 as design exercises intended to establish exterior and interior themes that could be modified for production versions of Pontiac sports and performance cars.

In 1964 Pontiac unveiled their newest concept car, which they dubbed the Banshee. During its development it was called the XP-833 project. This car was a small two-seater with a long, sweeping hood and a short rear deck. Several different versions were constructed, but only two drivable prototypes were ever built. One was a silver hardtop with a straight six engine and the other is a white convertible with a V-8. Both survive today and are in the hands of private collectors. The silver hardtop version of the Banshee can be seen in the classic car section of Napoli Indoor Auto, In Milford, CT.

The styling on these cars is highly reminiscent of what appeared on third-generation Chevrolet Corvettes in 1968. Another styling cue that made production was the design of the taillights, which are nearly identical to that found on first-generation Pontiac Firebirds. Indeed, the high performance and sensuous styling of the Banshee may have led to its demise. Head of Pontiac John DeLorean called this car the "Mustang Fighter" and rumor has it he fully intended to bring it to production. However, his bosses at GM felt that it would be a threat to the Corvette, cannibalizing its sales, and (if DeLorean had his way) outperforming it as well.
