Kenworth's dealer network is extensive — verify service center proximity for your primary operating corridors.

It uses the PACCAR MX-13 engine (510 hp, 1,850 lb-ft torque) with the PACCAR TX-12 automated transmission.

The W900 is Kenworth's iconic long-nose Class 8 truck with a conventional cab and long hood design dating to the 1960s. It is preferred by owner-operators for aesthetics, driver visibility, and customization options. It is also used in vocational and specialty hauling applications where its traditional design is advantageous. Production is limited — expect longer lead times.
Who makes PACCAR MX engines?
PACCAR MX engines are proprietary engines manufactured by PACCAR — the parent company of both Kenworth and Peterbilt. The MX-13 (13L, 510 hp) is the primary Class 8 engine. PACCAR designed and builds these engines in Columbus, Mississippi. They are not licensed from Cummins, Detroit, or Volvo — they are PACCAR's own powerplants.

The T680E is the battery-electric version of the T680. It is powered by a 484 kWh battery system providing up to 150 miles of range per charge. It is designed for regional distribution and urban freight where predictable routes allow scheduled charging. DC fast charging at up to 150 kW via CCS. Starting at approximately $250,000+.
How does Kenworth compare to Peterbilt?
Kenworth and Peterbilt are sister companies under PACCAR — they use identical PACCAR MX engines, transmissions, and axles. The differences are in cab design, exterior styling, dealer networks, and regional preference. Kenworth is generally preferred in the western US and Pacific Northwest; Peterbilt in the South and Southeast. Build quality and reliability are essentially identical.
