2019 Ford Ranger Raptor Bi-Turbo Engine & Powertrain – Video – Update
The Ranger Raptor powertrain features cutting edge technology to offer more power and torque, better fuel economy, less weight and with off-road specific calibrations for engine, transmission, driveline, steering, brakes and Electronic Stability Control (ESC) system.
In a revolutionary move to deliver incredible performance and responsiveness, a 10-Speed transmission is combined with a new 2.0-liter Bi-Turbo diesel engine in the Ranger Raptor to deliver a maximum of 213PS (157kW) of power and 500Nm of torque.
Ford engineers have tested the new powertrain extensively in order to prove out durability.
This testing includes running a ‘thermo cycle’ on the engine, heating both turbos to the point of glowing red for 200 hundred hours non-stop. It can withstand this torture thanks to the turbo bearings and low-pressure (LP) turbo being water cooled to reduce temperature, avoid over-heating and protect the air induction components.
Working as a team, the smaller, high-pressure (HP) turbo is connected in a sequence to the larger, LP turbo and is controlled with by-pass valves that determine the operating mode depending on engine speed. At lower engine speeds, the two turbos work in series, enhancing torque and responsiveness, while at higher engine speeds, the small HP turbo is bypassed, and the higher LP turbo provides boost to deliver more power.
The Ford-designed and Ford-built 10-speed automatic transmission is shared with the F-150 Raptor and has been created with high-strength steel, aluminium alloys and composites to optimize durability and weight. Having 10 gears means a wider ratio-span resulting in better acceleration and responsiveness. With more room to optimize gear spacing, engineers could customize gear progression far more efficiently than before, providing more accurate – and quicker – upshift and downshift capability.
The all-new electronic system features real-time adaptive shift-scheduling algorithms engineered to help ensure the right gear is selected at the right time. A unique transmission calibration also includes a ‘Live in Drive’ function, meaning that the paddle shifters are always available for manual gear selection override.
