2021 BMW 4 Series Coupe vs. Mercedes C-Class Coupe, Audi A5 Coupe

The Germans utterly dominate the compact luxurious coupe market, and now there’s a brand new big-grilled selection in the marketplace: the 2021 BMW 4 Series. BMW has chosen to disclose the automobile in base 430i type and warmer M440i xDrive trim. Because no stone is ever left unturned by the German competitors, this automobile already has opponents which are creepily much like it from practically each facet.

Homogeneous is one of the simplest ways to explain the three automobiles we’re pitting in opposition to one another. Some issues are noticeably completely different, just like the design, however discovering a transparent winner from the numbers isn’t any straightforward process. Even because the 2021 BMW 4 Series is completely new, each the Mercedes-Benz C-Class Coupe and Audi A5 Coupe are current designs. That means everyone is on a comparatively even footing going into this.

And simply to be clear, we’ve stored this comparability to the usual variations of the 4 Series and its competitors, as a result of the M4 hasn’t been revealed but. When it does, we’ll have loads to speak about between the Mercedes-AMG C 63 Coupe and the Audi RS 5 Coupe. Without additional ado, right here’s the comparability chart. Some figures are highlighted in order to level out a win for that mannequin over the others.


Every single automobile in its base type makes use of a 2.0-liter turbocharged four-cylinder engine. BMW ties with Mercedes in horsepower at 255 horses, however Bavaria takes a convincing lead with its stout 294 pound-feet of torque. The 21 pound-foot benefit over each the C 300 Coupe and A5 Coupe is probably going sufficient to be noticeable in acceleration, and the 0-60 mph occasions present precisely that.

BMW is quicker than everyone to 60 mph, in keeping with the producer estimates, coming in at 5.5 seconds with rear-wheel drive or 5.Three seconds with all-wheel drive. The benefit over Mercedes is relatively giant, however the Audi is correct behind BMW. They use completely different transmissions to get there. BMW makes use of one in all our favorites, the ZF 8-speed automated; Mercedes makes use of its personal nine-speed automated transmission, and Audi makes use of a dual-clutch seven-speed transmission, which can also be an inside job. All of them behave a bit otherwise in follow, however the BMW and Mercedes must be inherently smoother than Audi’s sportier dual-clutch transmission.

We don’t but have gas financial system for both BMW engine, however Audi is firmly forward of Mercedes on this class. We’ve been impressed with the real-world gas financial system out of the three Series up to now, and we think about the 4 Series will supply equally spectacular outcomes.

BMW manages to distinguish itself with its M440i xDrive. While the Mercedes and Audi opponents use V6 engines, BMW has put its glorious 3.0-liter turbocharged inline-six below the hood. We’ve pushed a number of automobiles with this engine (together with the 2021 Supra), and it’s splendid in sound, energy supply and sheer thrust. The 48-volt mild-hybrid electrical system is a neat bonus, too.

Despite all of that, the Mercedes-AMG C 43 nonetheless wins from a numbers perspective, because the twin-turbo V6 produces a hair extra horsepower and 20 pound-feet extra torque. It additionally has Mercedes’ multi-clutch automated transmission, whereas the opposite two make do with conventional eight-speed automatics. That doesn’t appear to assist in the 0-60 mph division, although, as BMW nonetheless estimates its M440i is faster than each the Mercedes and Audi S5. As these automobiles are solely a tenth or two completely different from one another, although, the distinction is negligible.

All three of those automobiles are mighty comparable, but when we’re going to assign a efficiency winner on paper, it’s going to be the BMW. Both variations of the 4 Series are faster to 60 mph than the others, and the candy inline-six engine is sufficient to have us leaning its method. The hole is shut, although, and driving all of them back-to-back might simply sway us in a unique route.

BMW: high; Audi: backside left; Mercedes-Benz: backside proper


Here’s the place BMW has thrown a curveball on this small coupe battle. The 4 Series is about three inches bigger than each the C-Class Coupe and A5 Coupe. It’s additionally wider than the others, and falls within the center on the subject of general peak.

That further size leaves the 4 Series because the clear winner within the all-important rear seat legroom class. It’s a full 2.5 inches bigger than the Mercedes and 1.Eight inches bigger than the Audi. It’s nonetheless comparatively small at 34.5 inches, however backseat passengers will certainly be extra comfy within the BMW than the others. Unless they’re particularly tall, as a result of BMW is available in final place for rear headroom. Audi leads the way in which right here with 36.1 inches. Coupes are inherently limiting in head area for rear seat passengers, so it’s no shock to see a bunch of low numbers on this class.

When it involves trunk area, the numbers say BMW has a transparent benefit. However, as we present in our BMW 3 Series baggage take a look at, the numbers aren’t telling the entire story. BMW’s method of measuring the area seems to be completely different indirectly in comparison with others. Until we are able to bodily begin shoving baggage into this coupe, we’re going to chorus from declaring it the last word utility coupe.


BMW has priced each the 430i and M440i to nearly completely line as much as Mercedes. At $46,595, the 430i is simply $350 cheaper than the C 300. The A5 Coupe is the most affordable of the bunch at $43,895.

The S5 can also be the most affordable efficiency variant, coming in about $6,500 cheaper than the M440i and C 43.

For the budget-conscious, the S5 Coupe is a good way to get right into a scorching German automobile for much less. However, possibly you’re a fan of the grille. If so, the brand new M440i might be your sort of automobile. It actually stands out greater than the others and makes a grander (for higher or for worse) entrance than any of its friends. We’ll additionally word the existence of the Lexus RC and Infiniti Q60 alternate options, each of which supply strong efficiency variants however do not utterly matchup to the Germans. If there have been a Japanese wildcard on this battle, it is the RC F and its spectacular 5.0-liter naturally aspirated V8 engine.

Now, examine all of them out in pictures.
