The BMW 4-Series’ natural rival is the Mercedes-Benz C-Class, which is newer with better tech.
The base engine in the C-Class isn’t as confident as the BMW’s base engine, but neither one is a bad pick.
The Audi A5 offers similar body styles to the BMW; its A5 Sportback is a stunner.
The Alfa Romeo Giulia is a sedan, but it’s entertaining to drive and deals should be plentiful.
The Lexus RC is a coupe only, and top powertrains could be a tempting proposition compared to the pricey BMW.
The Cadillac CT4 is new for 2020, we’ll report back once we’ve driven it.
