1. Pontiac Firebird Sprint

It is hard to believe that a Firebird is one of the obscure and rare classic muscle cars. The Firebird is one of the most popular and well-known Pontiac nameplates. In fact, from 1967 to 2002, it was the muscle car edge of the company. But there is one Firebird the automotive public forgot lost in the corridors of time all these years. And that is the 1967 to 1969 Pontiac Firebird Sprint.

They introduced the Pontiac Firebird in 1967 as the answer to the Ford Mustang. And along with the Chevrolet Camaro, it represented GM’s pony car weaponry. Since it was the height of the muscle car era, the public only paid attention to those high-powered V8s. However, Pontiac managed to sneak an interesting model into its lineup.

The secret of the Firebird Sprint was the engine. It had a 250 CID straight six with a single overhead camshaft. It developed 215 HP in the 1967 to 1968 model years, and 230 HP in 1969. Compared to the 350 and 400 CID V8, this was not impressive. But the Sprint’s six-banger with decent torque and the car’s small weight made it rev happily to 6,000 rpm. Compared to the nose-heavy V8 powered models, the Sprint was light with balanced handling and great driving dynamics.

In the days of V8 monsters, having a six-cylinder Firebird had an almost European feel. Unfortunately, not many people understood this model. Despite the modest price and unique characteristics, only a few thousand sold in its three-year production run. Today, the Firebird Sprint is a rare and seldom seen six-cylinder muscle car.
