The 1.5-liter TwinPowerTurbo inline-three hybrid engine powering the BMW i8 has just won the 2015 International Engine of The Year, breaking the 3-year streak of Ford's 1.0-liter EcoBoost.

With twin-scroll turbo aspiration and the help of an electric motor, the 1.5-liter hybrid powertrain produces a combined output of 362 PS while also achieving significant fuel economy as it only averages 47.6 km/l as claimed by BMW.

With multiple awards in hand, BMW states that these accolades further furnish the performance potential of the Efficient Dynamics technology package, which provides driving pleasure while also reducing fuel consumption and emissions.

Even though Ford's 1.0-liter EcoBoost was dethroned, it still won under the Sub 1-liter category. PSA Peugeot Citroen's 1.2-liter three-cylinder turbo engine was the winner in the 1.0 - 1.4 division while Mercedes-AMG's 2.0-liter turbo unit won in the 1.8 - 2.0 class.

Winners of the 2.0 - 2.5 and 3.0 - 4.0 liter categories are Audi's 2.5-liter turbocharged five-cylinder engine and McLaren's twin-turbo 3.8-liter V8. Topping the 4.0-liter and above category is Ferrari's 4.5-liter V8 that powers the 458 Italia.

Tesla's all-electric powertrain garnered victory in the Green Engine class while Ferrari was also able to win the Performance division with the 458 Italia powerplant.
