The 1972 Silver Arrow III, Buick Riviera concept, was designed by Bill Mitchell and introduced at the 1972 Detroit Auto Show. Based on a production Riviera equipped with a 455 V8 engine, the car received many new features, including a lower roofline and redesigned quarter windows.
Other advanced details included:
High-level warning lights doubled as secondary turn signals.
Six square halogen headlights upfront for better visibility during nighttime driving.
Four-wheel anti-lock brakes.
To maximize traction, the Silver Arrow III, like all Rivieras of 1971, was equipped with Max Trac, a forerunner of today's traction control systems.
The Silver Arrow was equipped with a plush, silver leather interior highlighted with black piping inside. Driver comfort was aided with an adjustable brake, accelerator pedals, and a tilt and telescopic steering wheel. Equipped with these features, no horizontal adjustment was needed for the driver seat.
There were two more versions of the Silver Arrow III. The Silver Arrow I and Silver Arrow II incorporated unspecified but relatively minor changes to Riviera's production.
