Corvette Five-Seater: The 1956 Corvette Impala Concept

More than once, Chevrolet designers have toyed with the idea of a four/five-place Corvette. One of them even joined the GM Motorama show car fleet for a time—the 1956 Corvette Impala. 

 

 

Work began on the five-place Corvette project, known internally at GM as XP-101, in July of 1955, and the Impala made its first public appearance in the General Motors Motorama at the Waldorf Astoria Hotel in New York on January 19, 1956. GM stylists Carl Renner and Bob Cadaret included key elements of the two-seater production Corvette in the Impala’s look, including the large, Italianate radiator opening in the front, filled with a chrome grille bar with 13 sparkling teeth. (Production 1953-1957 Corvettes used the same number of teeth, coincidentally.) Discrete badging on the front header panel and rear deck indicated that despite the rear seat, the Impala was indeed a Corvette.

The body—fiberglass, naturally, with a brushed stainless roof panel—rode on a conventional Chevy sedan chassis with 116.5-inch wheelbase, with short-long arm independent front suspension and a live axle with leaf springs at the rear. A Corvette 265 CID V8 equipped with two-four-barrel carbs, rated at 225 hp, was coupled to a Powerglide two-speed automatic gearbox, with the exhaust pipes snaked through the driveshaft tunnel. It was all fairly standard underneath, although real wire wheels with knock-off hubs supplied some sports car flavor. One area where the Corvette Impala broke new ground was in its innovative styling and interior.

 

A folding armrest allowed occasional three-abreast seating in the front, with roofor two more passengers in the coupe’s rear seat. The dramatic Interior fabrics included blue vinyl seat covers with a contrasting silver cloth in a heavy crossweave pattern. Instruments and controls were concentrated in a module directly in front of the driver, with an unusual speedometer that featured a horizontal array of sequential lamps that lit up in progressively brighter red as vehicle speed increased.

 

Originally finished in metallic turquoise, the Impala was repainted in medium metallic blue for the 1957 Motorama show season, and it made its debut in the new color at the Chicago Auto Show that year. While the Impala was said to be fully roadworthy, unlike many GM show cars, it was reportedly scrapped at some point after the ’57 show season, unfortunately.

As we know, there would never be a production Corvette with a rear seat, though there were a few more experiments. However, two of the show car’s features did find their way into Chevrolet showrooms in 1958: the novel reverse-angle C pillar and the Impala nameplate, which is used on Chevrolet passenger cars to the current day.

 

One thought on “Corvette Five-Seater: The 1956 Corvette Impala Concept

  1. Fantastic car, but Chevrolet is probably fortunate it did not take this path. The Corvette brand probably would not survive to today.
