Scania R450

Powertrain and Performance

The Scania R450 is powered by a 12.7L (DC13) inline-six engine, evolving from Euro 5 and early Euro 6 SCR-only variants to the advanced 'Super' DC13 with DOHC architecture introduced in 2021. Peak output is 450 hp with torque delivered from as low as 900 rpm on ‘Super’ models, supporting lower cruising speeds and improved efficiency. The Twin-SCR aftertreatment system in the ‘Super’ powertrain employs dual AdBlue dosing, enabling high combustion efficiency and further reducing fuel consumption by 8% compared to predecessors. Opticruise automated transmissions range from early GRS905 units to aluminum-cased G25/G33 models featuring a 14-ratio spread, integrated super-crawler/overdrive gears, and reduced internal friction for extended service intervals.

Chassis and Axle Options

Typical R450 configurations include 4x2 and 6x2 (mid-lift or tag axle) tractor units, with the NTG generation introducing the Modular Architecture Chassis (MACH) for enhanced flexibility in component placement. Rigid chassis variants are also available for specialist applications. Rear bogie setups can be specified for high-capacity work, and suspension options include full air or parabolic leaf springs. The R756 rear axle accompanies the ‘Super’ powertrain, maintaining the model’s low-rev operation philosophy.

Cab Variants and Driver Environment

Cab choices for the R450 encompass the R-Sleeper Normal, Highline, and, on pre-2016 units, Topline. The NTG redesign moved the driver position forward, lowered the dashboard, and adopted a larger windscreen for improved direct visibility. Interior upgrades feature quieter cabins, premium materials, and reworked storage, with air-suspended seating standard across most variants. Sleeper cabs offer increased standing height and storage, with upper bunks in Highline/Topline models designed for extended comfort.

Technology, Efficiency, and Customization

R450 trucks are equipped with progressive ADAS including AEB, ACC, Lane Departure Warning, and Blind Spot Detection. Integrated driver support systems coach for optimal fuel economy, while connectivity tools such as fleet management platforms are standard on later models. Factory options include auxiliary hydraulics for tippers or walking floor applications, tailored to operational needs. Consistently recognized for class-leading consumption, the R450 has set efficiency benchmarks in independent European tests, consolidating its status as a reference in long-haul transport.
