1966 Pontiac 2+2

By 1966, it was evident to car enthusiasts that midsize vehicles had taken over as the dominant force in the muscle car arena. Despite this, Detroit held firm to its proven strategy of pairing the largest cars with the most powerful engines. This approach ensured that the top contender in the intermediate muscle category also produced the ultimate full-size performance vehicle -- the 1966 Pontiac 2+2.

By 1966, it was widely recognized among enthusiasts that midsize models had claimed the muscle car crown. However, Detroit was hesitant to abandon its long-standing tradition of combining the largest cars with the best engines. Consequently, it was no surprise that the frontrunner in intermediate muscle cars also crafted the most exceptional full-size performance car -- the 1966 Pontiac 2+2.

Introduced in 1964, the Pontiac 2+2 initially served as a specialized package for the Catalina, featuring enhanced engine, suspension, and trim. By 1965, the 421-cid V-8 became standard, and in 1966, the 2+2 was elevated to a standalone model, retaining its foundation on the Catalina two-door hardtop or convertible. With its bold design and imposing dimensions, the 2+2 exuded unmatched charisma and delivered competitive performance against other high-performance vehicles.

The Pontiac 2+2 debuted in 1964 as a performance package for the Catalina, offering upgraded engine, suspension, and trim. In 1965, the 421-cid V-8 was included as standard, and by 1966, the 2+2 became a distinct model, still built on the Catalina two-door hardtop or convertible platform. Its striking design and commanding size made it a standout in terms of presence, while its performance capabilities rivaled those of other high-performance cars.

The standard setup featured a heavy-duty suspension, with options for even firmer springs and shocks. The premium Catalina interior was upgraded with bucket seats and a console, complemented by optional sport steering wheels and advanced instrumentation, including a tachometer and oil-pressure gauge. Distinctive exterior elements included "2+2" emblems, dual-lens taillights, and chrome side gills, while Pontiac's iconic eight-lug aluminum wheels served as the ultimate optional upgrade.

This was the only Pontiac model to come standard with a 421-cid engine. The base engine was a 338-bhp four-barrel, with two optional tri-power 421s offering 356 bhp and 376 bhp, respectively. The latter, known as the 421 HO, featured a high-output camshaft and valve train, along with a declutching fan, specialized exhaust manifolds, and chrome low-restriction air cleaners. Chrome accents also adorned the rocker covers and oil-filler cap.

Transistorized ignition was an available feature. The standard transmission was a three-speed manual, with optional upgrades to a four-speed or automatic at an additional cost. Manual versions were equipped with Hurst shifters. Optional extras included a limited-slip differential and gear ratios as high as 4:11.1.

Harnessing immense power and a balanced 55/45 weight distribution, the 2+2 could accelerate with minimal tire spin and navigate corners with remarkable precision. It offered a quiet, smooth ride, surpassing the harshness often associated with intermediate muscle cars. After reverting to an optional package in 1967, the 2+2 was discontinued, leaving behind a legacy as a proud symbol of an era when large cars, especially Pontiacs, dominated the roads.
