In 1973, Buick created a mid-sized luxury car called the Regal. It was a heavily optioned and highly trimmed Century, thus many of the Buick Regal parts will be interchangeable. However, the Regal was a notable improvement with woodgrain trim inserts throughout the interior, nicer upholstery, and a collection of convenience features. Of course, the same engines were offered throughout. The next generation debuted in 1978, and was downsized along with all other GM cars in that market segment. This, however, was far from a death sentence. In 1982, the first Grand National model was released and had a turbocharged V6 engine. Only producing 175hp at first, within 5 years Buick had their last model GNX putting out 245hp. Later generations, however, would not be as focused on performance. The Buick Regal would return to its roots and target a slightly upscale customer who wanted a relatively tame mid-size family car. From 1997-2004 Buick did produce a Regal GS with a supercharged V6 engine, but was not as fast as the Grand National. After a brief hiatus, the Regal returned to its position in the luxury mid-size market and is stealing customers from other non-GM carmakers. Fun fact: extremely limited edition Grand National Pursuit Special vehicles were produced with engines making 380hp and charting times under 4 seconds from 0-60mph.
