The 2.5-liter Ford HUWA turbo engine was produced at the Swedish plant from 2006 to 2010 and was installed in the first generation of the popular S-MAX minivan, but only before restyling. Such a power unit is essentially just a modification of the Volvo engine with the B5254T3 index.

Disadvantages of the HUWA engine
- The weak point of this motor are the valves and couplings of the phase control system;
- Also, many are faced with lubricant consumption due to clogged crankcase ventilation;
- For the same reason, oil often presses through the front camshaft oil seals;
- Carefully monitor the condition of the timing belt, as when it breaks, the valve bends;
- On a run of 150 – 200 thousand km, the fuel pump and turbine often require attention.
