Eric's Autos: 2021 BMW M440i
A few years ago, BMW stopped selling two-door versions of its 3 Series ... by calling the two-door versions of the 3 Series the 4 Series. When you add an M to 4, you get a high-performance two-door version of BMW's 3 Series sedan ... which isn't an M4, the much more expensive but fairly similar otherwise ultra-high-performance two-door version of the 3 Series BMW also sells.
Let's try to unwind that!
What It Is
The M440i is the high-performance version of BMW's 4 Series coupe, which is based on the 3 Series sedan.
It is similar in looks -- and under the hood -- to the BMW M4, which is an extremely high-performance coupe that's also based on the 3 Series but differs in being much less expensive -- $58,500 to start versus $71,800 for the M4.
Both have BMW's legendary inline 3.0-liter six-cylinder engine -- with a pair of turbos -- under the hood. But the M440i's version is mildly hybrid, with a 48-volt electrical system designed mainly to reduce emissions by enabling the engine to cycle off and on more often and less noticeably.
Also: The M440i is automatic-only and comes with all-wheel drive standard, while the M4 comes standard with a six-speed manual and offers all-wheel drive as an option.
The '21 M440i is all-new.
