Kenworth K100E – a cabover tractor unit from the PACCAR group in Kirkland: 14-litre six-cylinder engine, gross weight 23,000 to 24,410 kg, lengths from 6,900 to 7,150 mm
Kenworth K100E is a cabover (forward-control) tractor unit from the American truck maker Kenworth, headquartered in Kirkland near Seattle and part of the PACCAR group. The cabover layout, with the cab set forward over the front axle, was especially common in the 1980s and 1990s in US states with restrictions on overall combination length. The register entries K 100 E, K 100E and K100E denote the same type.

The register lists 3 versions with a 14-litre six-cylinder engine (14,000 to 14,016 cm³), kerb weights from 7,860 to 9,150 kg, gross vehicle weights from 23,000 to 24,410 kg, and vehicle lengths from 6,900 to 7,150 mm with widths from 2,500 to 2,550 mm.
As a heavy tractor unit, the K100E worked long-haul routes on US highways, where its compact cabover form allowed a shorter overall combination than conventional trucks such as Kenworth's own W900 for the same load area; as US length regulations changed, the cabover layout progressively lost ground to conventional long-nose tractors.
For a used example, check the chassis and axles for corrosion, clutch and gearbox condition, air brake system operation, and access to and the sealing of the forward-tilting cab; parts run through the Kenworth dealer network under PACCAR.

- Check the hour meter against the service records — a replaced instrument is the most common gap.
