M3 vs M4: What’s the Difference?

March 15, 2021
Red 2020 M4

What’s not to like about either of these beauties?  Nothing.  These BMW models are two of the most iconic in the manufacturer’s lineup.  The design engineers headed both cars into a daring and courageous new direction for 2021.  The biggest difference is that one is a sedan and the other is a couple.  There are a few subtle differences, as well, but not many.

2020 BMW M3

The 2020 BMW M3 sedan was proudly unveiled alongside the M4 coupe in the fall of 2020.  Both have BMW’s straight-six, twin-turbo, 3.0-liter engine that comes online with a horsepower of 473 for the regular model and 503 hp (375 kW) in the Competition series.  The Competition model can go from 0 to 60 in four seconds.  Starting prices for the 2020 M3 sedan is $69,900, while the Competition M3 model starts at $72,800.


It might be hard to tell the difference between the M3 and the M4 – they are very nearly identical.  The M3 is a sedan and would probably serve a family better than the M4 coupe.  If you don’t have kids you need to transport from place to place, the M4 might suit your style a little bit better as it’s a tad more like a sports car.  The difference between the M3 and the M4 also includes a hairline difference in suspension settings with the M3 having an extra 23kg.  The coupe is also 80mm wider than the sedan.


Nearly everything.  The sixth generation of these models with their striking looks added large dual “kidney” grills get your attention right away, being upfront and center in their aesthetically pleasing appearance.  Both versions of the car have chasses that are nearly identical (F80/F82).  Cost between the two is very similar as are the interior, components in the cars, safety features, and mechanics.  Both cars have a carbon fiber roof (you can get an optional moonroof at no additional cost), front and side-splitters that are M-specific, and wheels that are staggered (front 18s; back 19s).  The Competition model has 19-inch front wheels, while the back wheels are 20 inches.

The bottom line is that you can’t go wrong with either version of the stunning car.  Check them out in person today.
