competition, including a record of four consecutive overall titles between 2016 and 2019 and additional four ''Best Performance Engine'' titles. The powerplant also won the 2016 ''Best New Engine'' recognition at his debut. Between 2016 and 2018 the engine was classified at the first place in the ''3-to-4 litre'' class. Following the adoption of new power-based categories instead of the previous ones based on displacement, in 2019 the F154 variants won both ''550 to 650 PS'' and ''Above 650 PS'' awards. In 2018 the F154C engine was crowned ''by Johannes'' as the most significant engine since the launch of the International Engine of the Year in 1999.
