Mercedes CLA and GLA 45 AMG
Nobody expected Mercedes would enter the compact performance class or hot hatch class. After all, Mercedes is famous for big sedans that define luxury and comfort, rather than compact cars with screaming engines. And most of all, nobody expected Mercedes would do it so well.
The secret of the performance of the CLA, GLA and A Class 45 AMG is the unbelievably powerful 2.0-liter four-cylinder engine. It started with 345 HP, and for the 2017 model year, it produced a whopping 381 HP. For a comparison, the 2.0-liter four delivers as much power as the 5.0-liter V8 from a couple of years ago.
