Why Ford detuned its EcoBoost engine for the Ranger PHEV TechTricks365


Ford was willing to sacrifice performance for efficiency in developing its first Ranger plug-in hybrid (PHEV) ute, which features a heavily detuned version of the turbo-petrol four-cylinder engine found in the Ford Mustang EcoBoost.

While standard variants of the Ranger are offered with a choice of two turbo-diesel engines – a 2.0-litre four-cylinder and 3.0-litre V6 – the PHEV pairs a 2.3-litre four-cylinder turbocharged petrol engine with a 75kW electric motor.

It’s a version of the same engine that’s been used to power performance models both past and present, from the Focus ST and RS to the current Mustang EcoBoost. The EcoBoost powertrain also has a home in the US-market Ranger and the Volkswagen Amarok ute, which shares its platform with the Ranger.

But while outputs tally 232kW/475Nm and 222kW/452Nm for the Mustang and Amarok, respectively, the Ranger PHEV makes do with just 138kW and 411Nm, albeit supplemented by electric power.

Senior global product executive, Jim Baumbick, says the decision to detune the engine for this application was made in the name of efficiency.

“Could you add more performance? Yes. Would it come with tradeoffs? You bet – fuel economy,” Mr Baumbick, the vice president of advanced product development, cycle planning and programs, told Australian media in Iceland.

“One of the critical attributes of a hybrid is total cost of ownership and fuel-efficiency.”

Ford claims average fuel consumption of 2.9L/100km for the Ranger PHEV, while carbon emissions tally 66g/km.

In isolation, plug-in hybrid versions of the Ranger are an eco-friendly option in the mid-size ute market. However, key Chinese rivals have the Ranger beat in terms of efficiency – the BYD Shark 6 and GWM Cannon Alpha PHEV consume a claimed 2L/100km and 1.7L/100km, respectively.
