For the first time - in 1956 - all Buicks used the same engine: Buick's 322 cubic-inch V-8 that developed 200 horsepower and was capable of 110 miles per hour top speed.
All 1956 series cars, including the Special, now featured the rear wheelhouse cutout. The Special also featured three oval ventiports on the front fenders - a Buick styling signature. Standard special equipment included dual horns, map lights, front and rear armrests, directional signals, sliding sunshades, cigarette lighter and glove box light.
For 1956, Buick climbed to number three in sales, with 572,024 units sold, which represented nine percent of the total market share.
