Engine of the Year 2008
SUBARU 2.5-LITRE TURBO (FORESTER, IMPREZA, LEGACY, OUTBACK)
Few automotive manufacturers have given more to the boxer engine cause than Subaru. The past 12 months alone have seen engineers from the Japanese manufacturer introduce two brand new concepts to the world stage that make use of the flat cylinder formation: a 3-litre six-cylinder petrol engine, and the world’s first boxer diesel with 150bhp.
But the 65 judges on the International Engine of the Year Awards 2008 committee have bestowed a trophy on a different flat-four unit, and one that has triumphed in this category before. When it replaced the 2-litre turbo in 2006, this 2,457cc engine scooped first prize in the 2-litre to 2.5-litre category, beating BMW’s 2.5-litre straight six by two points. Fast-forward two years, and the same two engines are locked in battle for mid-range powertrain supremacy, and the outcome is the same – only the winning margin is down to a single point.
