Volvo FH420 Used Trucks - Current Offers for Sale

Powertrain Evolution and Performance Variants

The Volvo FH420 features a 12.8L inline-six engine, transitioning from the D13C (EUI, 2010–2012) to the D13K (Common Rail, Euro 6, 2013+) architecture. The D13K offers 420 hp (309 kW) at 1,400–1,800 rpm, with torque split into two primary variants: standard (2,100 Nm at 860–1,400 rpm) and Turbo Compound “I-Save” (2,400 Nm from 900 rpm). The I-Save system utilizes a second turbine to transfer waste exhaust energy to the crankshaft, delivering torque comparable to higher-rated engines. Gas-powered G13C 420 variants supply identical torque (2,100 Nm) through a diesel-cycle LNG system, with up to 1,000 km range.

Transmission and Driveline Technology

From 2010 onward, the I-Shift 12-speed AMT (AT2412F, AT2612F) became standard, with adaptive software (TP-LONG, TP-DIST) optimizing shifts based on gradient, load, and topography. Dual Clutch (SPO2812) is not offered on the FH420, retaining the lighter, single-clutch I-Shift for maximized efficiency. Predictive cruise control (I-See) manages gear changes, throttle, and engine braking using a GPS-connected, cloud-based topographic database, ensuring momentum is conserved throughout varied European terrain.

Chassis, Suspension, and Cab Configuration

The “New FH” platform (2013+) introduced modular chassis rails and expanded interior cab volume by one cubic meter over previous designs. Most FH420s use rigid front axles with air or parabolic leaf spring suspension, while rear air suspension (ECS4) with wireless remote height control is standard on 4x2 tractors. Independent Front Suspension is rarely specified for this power class. LNG options provide identical chassis spec and operational integration with diesel variants.

Steering and Safety Systems

Volvo Dynamic Steering (VDS) is available, overlaying traditional hydraulics with an electronically-controlled electric motor, offering torque overlay, disturbance rejection, and active driver assistance, including Lane Keeping and Stability Assist (from 2019+). Camera-based mirror systems and advanced HMI are introduced on the latest FH Aero models.
