The Car Connection's Take
TCC Rating
6.8
7.2
TCC’s Bottom Line
The redesigned 2021 BMW 4-Series has evolved into a technology powerhouse with wonderfully responsive powertrains, but the coupe lacks playfulness. Svelte, sporty, and somewhat understated, the 2021 Mercedes-Benz C-Class should be at the top of your compact luxury sedan shopping list.
