Mercedez Benz and BMW seem to be on agreement in at least one thing. They’re both working on three-cylinder petrol engines that will be launched within the next five years. The three-cylinder turbocharged unit will be installed in all Mercedes-Benz cars up to and including the C-class.
BMW, on the other hand, is designing cars that will suit the noise, vibration, and harshness associated with these three-pot engines. Dr. Thomas Weber, Daimler’s board member in charge of R&D, said that a three-cylinder engine in the C-class is “quite conceivable.” Daimler strategist Johannes Reisenrath said that to improve economy, it’s logical that from four cylinders, BMW can still go lower. Continued after the jump!
He cited that with a 1.2-liter three-cylinder, the car can have 16bhp with a turbo, plus 150-185lb ft, which is sufficient for a mid-sized car like the C-class. Its 6% fuel consumption benefit together with the 95g/km of CO2 fleet fuel consumption as a target means that it’s definitely an option it will consider. Mercedes is working to figure out a way to serve their customers economical vehicles. In a survey it conducted, consumers want three-cylinder cars to be as fast as their current cars. Reisenrath said that the three-cylinder vehicles have a “nice torque punch.”
With the advancement in turbocharging and gearboxes, the cars will be improved further. According to Autocar’s sources from BMW, the next 1-Series has been engineered to cope with the noise and vibration of a three-cylinder engine. BMW has had the same experience in its motorcycles, where its priority is reducing NVH.
