The 2020 BMW M4 Convertible has been around for five years now, and is still somehow part of the same first generation M4 which was brought to us by this European automobile manufacturer back in 2015. The lighter and stiffer 3 series, now known as the M4, has had eyes only for performance, and was destined to be an athlete from the moment it was born.
Vehicle images are guides only and may not reflect the model's exact specifications/features– exact specifications/features should be confirmed with the seller.
The 2020 BMW M4 Convertible sources power from a 3.0-liter turbocharged inline six-cylinder engine. This engine makes 425 hp and 406 lb.-ft. torque. But that doesn’t mean BMW forgot about people who are lifestyle enthusiasts. So the M4 Convertible allows you to take its top off on days you don’t feel like taking off.
With a powerful inline-six motor that still manages to return a combined fuel economy of 19-20 miles per gallon, and a car that costs $77, 650, the 2020 BMW M4 Convertible offers style and exclusivity like the Mercedes-Benz AMG C43 and the Jaguar F-Type. In fact, it even manages to be a whole league above them.

8.0/10
The 2020 BMW M4 Convertible is an all-inclusive trim of the M4 family. It has a hardtop sibling, the M4 Coupe. This drop-top M4 is based on BMW’s 3 series, and comes with plenty of standard features. To begin with, the 2020 BMW M4 Convertible is powered by the same 3.0-liter turbocharged inline six-cylinder motor standard across the 2 series Bimmers.
Other standard features include a six-speed manual transmission and rear wheel drive. While the rear wheel drive unit is a stand alone option, the six-speed manual transmission can be swapped with a seven-speed automatic one. Other options include an Executive package, carbon-ceramic brakes and wireless device charging.

The 2020 BMW M4 Convertible is undeniably one of the best convertibles you can own. It’s fast and it looks good from the inside and out. For the real joy of driving around in this rear-wheel driven, drop-top Beamer, get the one with the standard six-speed stick shift.
2020 BMW M4 Engine and Performance
8.2/10
The 2020 BMW M4 Convertible comes equipped with a 3.0-liter turbocharged inline-six motor. This powertrain configuration is standard across the range. The 3.0-liter turbo-six churns 425 hp and 406 lb.-ft. torque. Another no-choice option on the 2020 BMW M4 Convertible includes a rear-wheel drivetrain.

All the power that the 3.0-liter inline-six makes, is sent to the wheels at the back of this Bimmer with the help of a six-speed manual transmission. There’s an optional seven-speed M Double Clutch Transmission on offer too.

While most other competitors offer an automatic transmission as standard, this Beamer shies away from it. Also, as compared to the other cars, the M4 Convertible’s engine is the most powerful on paper.
How fast is the BMW M4 Convertible?
Any car that makes as much power as the M4 Convertible does, is bound to be fast, and this Beamer does not disappoint. As soon as you put your feet down on the pedal, the 3.0-liter turbocharged is sprung to life. The motor delivers all the power to the two wheels at the back, and the M4 Convertible takes off as if it were running away from its hunter.
2020 BMW M4 Convertible hits 0-60 MPH in 4.4 Sec
The drop-top setup of this M4 does take a slight edge of this Bimmer’s performance though. All the extra weight that is added as a result of the convertible mechanism, makes this Bimmer 0.3 seconds slower than its Coupe sibling. However, even with the increased weight, the M4 Convertible rockets past the 60 mph mark in as little as 4.4 seconds.

All the other cars are faster in getting to the 0-60 mph mark as compared to this BMW. But some of the cars have two seats only, while the BMW M4 Competition can seat up to 4 people. Also on a quarter mile, this BMW is much faster than a lot of cars.
What about the braking performance of the BMW M4 Convertible?
It’s not just the way this Beamer accelerates but also the way it brakes that makes the M4 Convertible an extremely fun-to-drive automobile. For the year 2020, BMW has equipped the M4 Convertible with 15.0-inch cross-drilled brakes at the front, and slightly smaller 14.6-inch discs at the back.
2020 BMW M4 Convertible has Front Brake of 15.0 in.
The front brakes get six-piston calipers while the smaller ones at the back get four piston calipers. For all the more improved braking performance, BMW offers carbon-ceramic brakes as an option.

As compared to the rest of the competition, the 2020 BMW M2 Convertible gets the biggest brakes in the segment. It seems only fair that this convertible be equipped with such stout rotors as it is the heaviest car in this class after the Mercedes-Benz AMG C 43 Cabriolet.
What about its driving dynamics?
There are several cars that make a lot of noise about how powerful their engines are, but take them in on a curve and you probably won’t be able to come out of it. That is not the case with the 2020 BMW M4 Convertible though. All Beamers are known for their great steering response, and the M4 Convertible is no different.
The 2020 BMW M4 Convertible is one heavy car. Thanks to the mechanism which allows you to take it’s top off and on again. However, the engineers at BMW decided to take advantage of the extra weight since they could not get rid of it. Instead of making the roof out of cloth, they used metal. Thus improving the overall body rigidity of the M4 Convertible.
2020 BMW M4 Convertible Front View
Also noteworthy is the superb body control. The M4 Convertible does feel a little less rigid with its top-down, but the accurate steering makes it incredibly easy for the driver to scythe this Bimmer through corners at mind-blowing speeds. A special electronic rear differential allows for a lot of controlled fun. However, this Bimmer is a joy to ride on most roads.
The 2020 BMW M4 Convertible comes equipped with adaptive sport-tuned suspension from the factory. That along with the standard 18-inch wheels ensure a real joy of driving. This BMW also benefits greatly from its 48:52 front-rear weight distribution. As all the power from the engine is sent only to the rear wheels, a heavier back-end helps keep this M4 Convertible under control.
2020 BMW M4 Fuel Economy
5.0/10
BMW optimizes its engines in a way to strike as much balance as possible between performance and practicality. The 2020 BMW M4 Convertible’s powertrain is also part of the same heritage. The 3.0-liter turbo-six is as fuel-efficient as can be. However, the MPG figures vary with the choice of transmission paired to the M4 Convertible’s engine.
The seven-speed dual-clutch transmission is more fuel-efficient with a combined MPG rating of 20 miles per gallon. The six-speed manual unit manages to return a combined MPG rating of 19 miles per gallon, which is not bad for a car that offers so much performance. However, this Beamer gets the smallest fuel tank, and that means more stops at fueling stations. That’s a compromise that M4 Convertible owners will have to make.

When it comes to fuel efficiency numbers, the M4 Convertible does seem to suffer in comparison. Almost all of its rivals have better fuel economy and range. Although one must remember that the M4 Convertible can seat 4 people, unlike the Porsche or the Jaguar, which seat only 2. Also, the 2020 M4 Convertible is significantly heavier than them.

7.1/10
Some might not like the way an M4 Convertible looks from the outside. To them we say, the true joy of driving is achieved from the inside the car. You will feel as your horizons alter the moment you step inside the 2020 BMW M4 Convertible because it simply cannot be that you take the driver’s seat in any M car for that matter and do not feel a sense of luxury and premium-ness taking over.
At the front are the M Sport heated and power-adjustable seats. The front row seats are very accommodating and will be incredibly comfortable even on long journeys. The same cannot be said for the second-row seats though. The legroom in the second row is a bit compromised. A downside of the convertible mechanism, but there’s a lot of headroom.
2020 BMW M4 Convertible Front and Rear seats
Overall, the cabin feels exceptionally well-made. Leather upholstery is standard, and the surfaces that are not covered in it, you’ll hardly notice. The quality of material used feels premium and there’s hardly any scratchy or plastic-y nook or cranny to be found.

No other competitor of the 2020 BMW M4 Convertible offers the kind roominess it does in general. Front row headroom and legroom are simply best in class. And even though the M4 Convertible suffers a bit because of its soft-top design, it offers to free up a lot more space on the inside.
Does it come loaded with tech inside?
The 2020 BMW M4 Convertible boasts BMW’s iDrive 7 infotainment interface on an 8.8-inch touchscreen display which is available with Apple CarPlay but misses out on Android Auto. BMW’s infotainment is well received by people all over, and everyone has come to acknowledge it as one of the best infotainment systems. The 8.8-inch touchscreen features the following:

What about utility?
The drop-top setup of the 2020 BMW M4 Competition has its own quirks. The most noticeable of them all is the compromise that this Beamer makes on its usefulness. The mechanism which allows you to feel the wind in your hair adds a significant amount of weight, and also takes up a lot of space.
2020 BMW M4 Convertible Cargo Volume with rear seats up 7.9 ft.3
Now, there’s only so much space inside the BMW M4 Convertible. Still, this Bimmer manages to maximize comfort and space. The trade-off is its relatively smaller trunk. However, there are several cup holders and cubby spaces inside the cabin to hold your belongings.

BMW has a very unique way of putting the entire car together. All BMWs look somewhat the same up to some extent, but certain subtle styling cues are unique to each one of them. As far as the 2020 BMW M4 Convertible is concerned, BMW completely redesigned the panels from the 3 series and topped it off with a retracting roof.

An approaching M4 Convertible features an aggressive front bumper. The trademark BMW’s air curtain design houses the typical BMW kidney-style grille with the M badge upfront. The sharply-styled LED headlights all the more cool factor. At the sides, above the standard 18-inch wheels, flared fenders and sculpted doors disguise the M4’s heft.
Moving on to the back, the air curtain design follows. The M-specific diffuser houses the signature quad exhaust pipes, a trademark of all BMW M cars. The BMW organic OLED taillights help put the entire car together.

BMW M4 Convertible vs. Mercedes-Benz AMG C43
The Mercedes-Benz AMG C43 is significantly cheaper than the BMW M4 Convertible. But the M4 Convertible will give you value for every buck you spend on it. The M4 Convertible’s engine is bigger and more powerful. The availability of space inside the cabin, in general, is much better than that in the AMG C43. Plus the M4 Convertible is loaded with tech and features, probably not as much the Merc. In all honesty, though, you might not even know what to do with all the tech that the AMG C43 has to offer.
2020 Mercedes-Benz AMG C43
BMW M4 Convertible vs. Jaguar F-Type
The Jaguar F-Type and the BMW M4 Convertible have more in common than one can think. The M4 Convertible does everything that the F-Type does, only better. To top it all off, the M4 comes with an additional row. The F-Type can seat only two people, but in the M4 Convertible you can seat up to four. And in case you don’t need a second row, it can double as extra storage space.

2020 BMW M4 Final Verdict
If you are in the market for a car that offers unmatched performance, plenty of comfort and convenience features, and also lets you take off the roof for those days when you really want to soak up the sun, the BMW M4 Convertible is definitely the way to go. The M4 Convertible is subtle yet aggressive, and packs a punch strong enough knock ‘em all out yet delivers a sense of elegance. It is a great car for the kind of money it costs. Yes, the price is on the more expensive side of things, but you know what they say, “when you are good at something, never do it for free.”

Everything makes sense when you drive a bmw. The price point, the name hype, and the sports tag to it. Bmw is always known for the driveability of their cars and M4 helps will clear all the air on that once you hop in. It not only leaves a driver grinning on the seat when hitting the gas, it surprises with the high speed stability and no vibration on the steering wheel. On the ground level, the only issue I see with the driving is the tires(not bad) but run flat ones would have been better.

The German automaker seems to be stuck with the inlines which are good for power but can't be reworked for better handing precision. This is no regular car and should come with a far more better steering and tire connection which unfortunately isn't there. It however hasn't hampered my driving experience much but these basic issues are not appreciated at all. Glad they at least thought about having an optional manual transmission.
