Checker built automobiles around one simple idea: keep them working. Its taxis were designed for constant commercial use, heavy passenger loads, rough streets, and extremely high mileage. The company eventually produced some of the longest-lived American taxi designs ever made, with the famous A8 architecture remaining fundamentally recognizable until production ended in 1982.

Checker Model T

The Checker Model T was introduced in 1933 as one of the company’s important prewar taxi designs. It used a Lycoming straight-eight engine and was developed during the period when Checker was expanding its purpose-built taxi business. The Model T was also closely related to the Auburn Saf-T-Cab, giving it an unusual connection to the Auburn-Cord-Duesenberg organization. Today, surviving Model Ts are exceptionally rare reminders of Checker’s prewar engineering.

Checker Model A4

The Checker Model A4 was one of the company’s early postwar taxi models, continuing the rugged engineering philosophy established by the earlier A2. Built around a conventional six-cylinder drivetrain and a spacious taxi body, it was designed for the demanding conditions of commercial service. Most A4s spent their working lives carrying passengers rather than being preserved, which explains why surviving examples are now exceptionally rare.

Checker Model A8

The Checker Model A8 was arguably the most important design in the company’s history. Introduced in 1956, its boxy body established the basic appearance that Checker would retain for decades. The heavy-duty chassis, bolt-on exterior panels, and service-friendly construction were specifically suited to taxi operators. The A8 also laid the groundwork for the A9 and the later A11 and A12 models, making it one of the most influential forgotten Checkers ever built.

Checker Model A9

The Checker Model A9 updated the A8 design for 1959 with quad headlights and revised front-end styling while retaining the same fundamental architecture. It was also important because Checker began expanding beyond the traditional taxi market around this period, eventually offering civilian versions of the platform. The A9’s relatively short production run and hard commercial life mean that surviving examples are extremely uncommon. Only a small number of pre-1960 Checkers remain today.

Checker Superba

The Checker Superba was the company’s first serious attempt to sell a Checker directly to private customers. Introduced for 1960, it was derived from the A9 taxi but offered additional equipment and a more passenger-oriented interior. It was available as a sedan and station wagon and remained in production until 1963. Although it never became a mainstream competitor to Detroit’s major family cars, the Superba demonstrated that Checker’s rugged taxi engineering could be adapted for everyday civilian use.

Checker Aerobus

The Checker Aerobus took the company’s durability philosophy to an extreme. Built from 1962 through 1977, it stretched the Checker platform into a huge airport and hotel shuttle available in six- and eight-door sedan forms as well as long station-wagon configurations. Some versions could carry up to twelve passengers, while the later Aerobus 15 accommodated even more. Only a few thousand Aerobuses were built, making surviving examples far rarer than ordinary Checkers.

Checker A11

The Checker A11 became one of the final and toughest generations of the legendary Checker taxi. Built from 1961 through 1982, the basic design endured for more than two decades while other American taxis changed repeatedly. Heavy-duty components and easily serviced Chevrolet engines helped these cars survive enormous amounts of commercial use. One famous New York A11 accumulated nearly one million miles before retirement, while the final Checker built was also an A11.
