Mercedes-AMG Pumps 416HP From Its Puny Little 2.0-Liter Engine, Yah!
Mercedes-AMG will use the engine in a wide range of models, and they will all make their way to the United States meaning we will get to partake in this powerful four-banger. The engine will also be used in a lesser trim models where it will produce 382 hp and 354 lb-ft of torque. The new engine will be used in the A45, CLA45, GLA45, and the GLB45.
The engine is assembled by hand by a single technician using Industry 4.0 methods. AMG says that the process it uses gives maximum flexibility, is transparent, and highly efficient. AMG says that it created "ideal working conditions" in a bright, precisely organized, and clean environment for its employees.
The engine is designed so that the turbocharger and exhaust manifold are positioned at the rear on the side of the firewall when viewed from behind. That places the intake at the front allowing for the flattest and most aerodynamic front section design. Mercedes-AMG says that the new arrangement allows for improved air ducting with shorter distances and fewer divisions on the intake and exhaust side.
The turbo used is a twinscroll unit with responsiveness at low engine speeds with high power in the upper rpm range. The engine is designed to allow for higher torque at lower engine speeds. The shafts of the compressor and turbine have roller bearings for the first time that reduce mechanical friction. The turbo has a maximum speed of 169,000 rpm; the boost pressure is 2.1 bar or about 31.5 psi, the base version uses 1.9 bar of boost.
We're definitely eager to see this new engine -- especially its high-performance variant -- in action on the race track. With over 400 horsepower on tap, the engine is more powerful than many twin-turbocharged V6 engine currently on the market.
Mercedes product development isn't limited to internal combustion engines; the company recently started EQC production. This vehicle is an electric crossover with 400hp that has been designed to fight the Tesla Model X.
