A redesigned Fleetline with reduced body contour and integrated rear fenders was offered for the 1949 through 1952 model years.

Many are made into street rods, with the common Chevrolet 350 small block V8 and the 350 or 400 turbo transmission being used.

In the 1941 and 1942 model years, the 216 cubic inch inline-six "Blue Flame" engine was the only one offered.

Also in 1950, a 235.5 cubic inch, single-barrel carburetor, six-cylinder engine producing 105 hp (78 kW) was added.

In very early models, the transmission was a manual synchromesh three-speed, with vacuum-assisted shift,[9] in which the "three-on-the-tree" shifter was able to be moved between gears by the slightest pressure on the lever.

Not a Chevrolet option but a popular after market feature was a large external sunshade that protects the driver from glare off of the metal dashboard.

The interior has cloth bench seats and a metal dash sometimes with a simulated burle woodgrain.

In the earlier model years the clock is integrated into the glove compartment door and is of a manual-wind seven-day type.
