In the past big eight cylinder engines were the norm under the hood of high-performance vehicles, but thanks to turbocharging and direct-injection technologies, smaller engines are now able to match the output of larger engines. Mercedes' AMG performance division has proved this with the 355-hp 2.0L four-cylinder engine that does duty in the CLA45 AMG and GLA45 AMG. Now it's being reported that AMG may use the turbocharged engine in some of its larger models, like the C and E-Class models.

What Car? recently spoke to AMG boss Tobias Moers who revealed that the automaker is considering using the 2.0L twin-turbocharged engine in several other models, which means a C45 AMG or E45 AMG could happen.

“It’s probably something we should consider,” Moers stated. “We haven’t decided anything but in my own mind, as an engineer, I think it could be an interesting solution to have a high-powered four-cylinder petrol engine that is not a compact — maybe even a saloon.”

If you're wondering if AMG will ever build a high-performance diesel model, the chances are slim. “The market for highly tuned diesel performance cars is very small.”
