Mercedes-Benz likes to make a rather large song and dance about the fact that the 415hp A45 S utilizes the most powerful four-cylinder engine in mainstream production. It’s an incredible unit which you can read all about by clicking these blue words.

The B45 also gets new 20-inch wheels and height-adjustable sports springs that lower the hot hatch by up to 3cm.

All of Brabus’ work means a 0-100kph time of just 3.7sec, and obviously, there’ll be worries about the stresses placed on a four-cylinder engine that’s making as much power as a Porsche 959, so the B45 also comes with a three-year/100,000km Brabus Tuning Warranty.

See, it is sensible after all.
