Fast, small German cars are back, compares and contrasts the Mercedes-Benz CLA45 AMG with the brand new BMW M235i. Mercedes and BMW have had small car rivalries like this in the past, most notably the Benz's 190E 2.3-16 versus Bimmer's E30 M3. Fast forward three decades, and times have changed. Forget natural aspiration, as turbocharging rules the day. The CLA45's engine is even mounted sideways in a complete departure from Mercedes' tradition. Regardless of the details, both cars are fast and fun. Watch and enjoy!
