Rolling chassis

Last updated

A rolling chassis is the fully-assembled chassis of a motor vehicle (car, truck, bus, or other vehicle) without its bodywork. It is equipped with running gear (engine and drivetrain) and ready for delivery to a coachbuilder to be completed. Historically, bespoke luxury automobiles were finished inside and out to an owner's specifications by a coachbuilder, and specialty vehicles (such as fire engines) were outfitted by firms devoted to that task.

The term is also used to describe the chassis and running gear of a vehicle in a body-off restoration.

Automobiles

Prior to unibodied vehicles, the rolling chassis stage was common to the manufacture of all motorcars. Mass-produced cars were supplied complete from the factory, but luxury cars such as Rolls-Royce were supplied as a chassis from the factory to several coachbuilders, in its case J Gurney Nutting & Co, Mulliner, Park Ward, and others. These handcrafters would supply a body and interior to a customer or dealer's specifications. Important names in the United States included Lebaron, Fleetwood, and Rollston.

Over time top luxury automakers absorbed one or more of their vendors and moved vehicle finishing in-house.

Heavy vehicles

Separate chassis remain in use for almost all heavy vehicles ranging from pickup trucks to the biggest trucks and commercial passenger carrying vehicles.

The rolling chassis is delivered to the commercial body maker, coachbuilder, or bulk transporter on its own wheels, under its own power.

Body-on-frame is a traditional motor vehicle construction method whereby a separate body or coach is mounted on a strong and relatively rigid vehicle frame or chassis that carries the powertrain and to which the wheels and their suspension, brakes, and steering are mounted. While this was the original method of building automobiles, body-on-frame construction is now used mainly for pickup trucks, large SUVs, and heavy trucks.

The Austin 7 is an economy car that was produced from 1923 until 1939 in the United Kingdom by Austin. It was nicknamed the "Baby Austin" and was at that time one of the most popular cars produced for the British market and sold well abroad. Its effect on the British market was similar to that of the Model T Ford in the US, replacing most other British economy cars and cyclecars of the early 1920s. It was also licensed and copied by companies all over the world. The first BMW car, the BMW Dixi, was a licensed Austin 7. In France they were made and sold as Rosengarts, and in the United States they were built by the American Austin Car Company. In Japan, Nissan also used the 7 design as the basis for their first cars, although not under licence. This eventually led to a 1952 agreement for Nissan to build and sell Austins in Japan under the Austin name.

The 4000 lb (1800 kg) car won the 24 Hours of Le Mans in 1924, with drivers John Duff and Frank Clement, and again in 1927, this time in Super Sports form, with drivers S. C. H.
