For the fifth year in a row the winner of the International Engine + Powertrain of the Year award in its class is the powertrain of the BMW i8.

This year it was competing in a brand new category: Best Hybrid Powertrain. A big surprise was the distance in score: The powertrain of the BMW i8 took the lead earning 233 points against 138 points for the competitor finishing in second place.

The BMW i8’s powertrain came onto the market in 2014 and has scooped the coveted award in its category every year since. In that first year, it was also crowned Best New Engine and took the overall award for good measure. By collecting an award again in 2019 –

The latest version of the BMW i8 combines sports-car performance with fuel economy worthy of a compact model. Its three-cylinder combustion engine delivers 170 kW/231 hp to the rear wheels. The electric motor, whose output has now been upped to 105 kW/143 hp, draws its energy from a lithium-ion battery – which can be charged from a conventional domestic power socket – and sends its power to the front axle.

The more powerful of the drive duo powers the rear wheels and uses the electric boost from the hybrid system to deliver hallmark BMW driving pleasure combined with trailblazing efficiency. The sprint from 0 to 100 km/h (62 mph) takes just 4.4 seconds, yet combined fuel consumption – as calculated in the EU test cycle for plug-in hybrid vehicles – stands at 2.0 litres per 100 kilometres (141.2 mpg imp), plus 14.5 kWh of electrical energy.

This year was the 21st edition of the International Engine of the Year awards. Since the event’s inception, power units developed for models from the BMW Group’s brands have racked up a total of 70 wins in their categories and overall. The task of electing the best engines in numerous different classes falls to a jury of experts, which this year was made up of 70 motoring journalists from 31 countries.
