The Kalmar KVD440/441, also variously known as Tjorven or DAF Kalmar, is a delivery van based on the DAF 44, made in Sweden. The vehicle inherited the air-cooled, 844cc boxer engine and Variomatic transmission from the DAF 44.

Van covered transportation vehicle

A van is a type of road vehicle used for transporting goods or people. Depending on the type of van it can be bigger or smaller than a truck and SUV, and bigger than a common car. There is some varying in the scope of the word across the different English-speaking countries. The smallest vans, microvans, are used for transporting either goods or people in tiny quantities. Mini MPVs, Compact MPVs, and MPVs are all small vans usually used for transporting people in small quantities. Larger vans with passenger seats are used for institutional purposes, such as transporting students. Larger vans with only front seats are often used for business purposes, to carry goods and equipment. Specially-equipped vans are used by television stations as mobile studios. Postal services and courier companies use large step vans to deliver packages.

DAF 44 small family car

The DAF 44 is a small family car that was introduced in September 1966 by the Dutch company DAF. It was the first car to be built at the company's new plant at Born in Limburg. Styled by Michelotti, it represented a cautious move upmarket for the company which hitherto had produced, for the passenger car market, only the smaller slower Daffodil model.


Variomatic is the continuously variable transmission (CVT) of the Dutch car manufacturer DAF, originally developed by Hub van Doorne: It is a stepless, fully automatic transmission consisting of a "V" shaped drive belt and two pulleys, each of two cones, whose effective diameter can be changed so that the "V" belt runs nearer the spindle or nearer the rim, depending on the separation of the cones. These are synchronized so that the belt always remains at the same optimal tension.

In the mid-sixties the then Postverket (Swedish Mail) needed a new vehicle for mail delivery, and contacted Kalmar Verkstad, who developed and built it between 1969 and 1971. On the export market it was simply called Kalmar. In addition to the generous heating provided by the air-cooled engine, to provide appropriate heating for postmen, some units were fitted with a gasoline-powered Eberspächer heater under the driver's seat, with a dedicated exhaust pipe.

Kalmar Verkstad company

Kalmar Verkstad AB (KVAB) was a Swedish train and automobile manufacturer in Kalmar, Sweden that made the Tjorven and Terminal. KVAB was founded in 1902 and closed 2005 by Bombardier.

"Tjorven" was a nickname given to the Kalmar as its rather frumpy appearance was reminiscent of a contemporary Swedish television character of that name.

The name "Tjorven" comes from a popular Swedish family show on television in the early 1960s. Based on a script by the Swedish author Astrid Lindgren, the story is about a number of characters living in the archipelago outside Stockholm. A central character is a plump and sunny little girl nicknamed Tjorven.

It was RHD for easy driver access to road side letter boxes, frame-built with a fiberglass bodywork.

Letter box mailbox where mailmen or other people deposit letters to specific addresses

A letter box, letterbox, letter plate, letter hole, mail slot or mailbox is a receptacle for receiving incoming mail at a private residence or business. For the opposite purpose of collecting outgoing mail, a post box is generally used instead. Letterboxes or mailboxes use the following primary designs:

Fiberglass (US) or fibreglass (UK) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet, or woven into a fabric. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinylester—or a thermoplastic.

Heater core

A heater core is a radiator-like device used in heating the cabin of a vehicle. Hot coolant from the vehicle's engine is passed through a winding tube of the core, a heat exchanger between coolant and cabin air. Fins attached to the core tubes serve to increase surface for heat transfer to air that is forced past them, by a fan, thereby heating the passenger compartment.

Idle reduction

Idle reduction describes technologies and practices that minimize the amount of time drivers idle their engines. Avoiding idling time has a multitude of benefits including: savings in fuel and maintenance costs, extending vehicle life, and reducing damaging emissions. An idling engine consumes only enough power to keep itself and its accessories running, therefore, producing no usable power to the drive train.
