1. Mercedes-Benz CLA 45 AMG - 4.2 seconds
The Mercedes-Benz CLA-Class has already done wonders for the German automaker in terms of sales, and the CLA 45 AMG model is setting a new benchmark in luxury performance. Boasting the world’s most powerful four-cylinder engine, the CLA 45 AMG is powered by a 2.0-liter turbocharged four-cylinder engine with 355 hp and 332 lb-ft of torque. Perhaps even more impressive is the fact that the CLA 45 AMG delivers 23 mpg in the city and 31 mpg on the highway. Best of all, real-world testing proves that the CLA 45 AMG accelerates to 60 mph in 4.2 seconds, even faster than what the German automaker advertises. You can have it all for just $48,375.
