2020 BMW 420i M Sport Coupe Review: To The 4

Pricing & Rivals 

If you want more, there’s the 430i M Sport Pro, which should be enough to please any driver unless they are willing to wait for the inevitable M440i or the new M4. 

As mentioned in our comprehensive launch story, you can have the 4 Series Coupe in any trim you want, so long as it is M Sport and with a 2.0-litre turbo engine.

The standard 420i M Sport, as driven here, comes with 18-inch wheels and non-M Sport brakes, while the jump up to 430i M Sport Pro nets you nicer seats, M Sport brakes, adaptive M Sport suspension, and with an optional rear-diff for even more fun. That’s a S$48k price difference though, but we suspect the 430i will be ffully capable of hunting sports cars when corners appear. 

Audi’s A5 is the closest German competitor

In the small-midsized executive coupe class, there are plenty of rivals for the 420i including the Audi A5 2.0, Mercedes-Benz C 180 Coupe, Infiniti Q60, and Lexus RC Turbo. 

All of these cars are more relaxed than the 420i, but can’t hold a candle to its handling prowess. The Audi and the Lexus run the closest: The A5 is more comfortable and handles well but isn’t as involving, while the Lexus is the unique, Japanese spin on what an executive coupe should be, its handling is almost as sweet, but buried under a layer of refinement.  


The 4 Series’ nose-nod to its forebears has more significance now that we’ve found out how it drives, it brings the brand back where it belongs. Once upon a time you could rely on a BMW coupe to be the best-driving amongst mainstream luxury brands, and in hindsight, that hasn’t been the case in the past decade. But with cars like the current Z4, the 8 Series, and the new 4 Series, it should be a comfort to long time fans of the brand that despite its drive to the future, it’s not putting drivers in the backseat.
