The BMW 4 Series is a two-door coupe and cabriolet that shares many similarities with the 3 Series sedan. Except for the plug-in hybrid system, powertrain options are the same. There’s the base 430i model featuring a turbocharged 2.0-litre four-cylinder engine, as well as the sportier M440i and hardcore M4, both with a turbocharged 3.0-litre six-cylinder engine. For 2023, a limited-edition M4 CSL with just 42 units for Canada was added to the lineup.
