Overall Rating


This feature speaks about the BMW 840i Convertible, which is the base convertible model of the 8-Series lineup. The 840i Convertible houses a 3.0L Inline-6 engine that can fabricate a punchy 335 hp, along with 368 lb.-ft. torque. The 840i Convertible comes out as an ideal mix of handsome looks inside-out and smashing performance that can put other cars to shame on the freeways and can get you a number of looks as well.

The BMW 840i Convertible is priced competitively as well. The MSRP for the 840i Convertible, in its rear-wheel-drive configuration, starts from $97,400. This pricing lands the 8-series convertible in a pit with some of the renowned heavyweights of the segment such as the Jaguar F-TYPE, the Porsche 911 Carrera Cabriolet and the Mercedes-Benz SL 450 Roadster. With such tough competition at hand, will the 8-series be able to weave the magic it once had in the 90s? Well, scroll down to find out.

We Recommend

There is absolutely no difference between the 840i convertible and the 840i Convertible xDrive, except for the drivetrain. The xDrive is $900 more expensive than the base 840i Convertible and accounts for a more engaging driving experience. So we’d recommend you to go for the BMW 840i in its RWD configuration.

2020 BMW 8 Series Convertible Engine and Performance

9.0/10

The 2020 BMW 840i convertible brings the tenor of inline engines into action in the all-new BMW 8-series. The Bimmer’s biggest grand tourer engages a 3L twin-turbocharged 6-cylinder engine that generates 335 hp and 368 lb.-ft. Of peak torque, which kicks in as early as 1600 rpm, thus propelling the ride from naught to high-speeds in a fraction of seconds.

To carry-out the transmission duties smoothly and effortlessly, the company fits an eight-speed automatic transmission panel in the entire 8-series lineup. However, this transmission panel is not just any ordinary panel, rather it’s a sport automatic transmission with Sport and Manual shift modes. There is also a presence of paddle-shifters, which come mounted on the steering wheel, for the times, the enthusiast within you demands more than just a regular shot of thrill.

The Bavarians have put their heart and soul in manufacturing the 8-series. However, in this case, the 840i does not seem like an angry, growling monster. The BMW 840i Convertible can be perceived as the most incapacitated offering of the segment, in terms of output figures. The Jaguar F-TYPE P380 R-Dynamic generates the most macho set of power figures, with 380 hp and 339 lb.-ft. of torque. The Porsche 911 Carrera Cabriolet, making a close chase, presents us with 379 ponies and 331 lb.-ft. of spinning force. The Mercedes-Benz SL 450 Cabriolet does not lag much behind either, with 362 steeds along with 369 lb.-ft. Of peak torque.

How fast is the BMW 8 Series convertible?

Though this Bimmer’s power figures may make it seem like a feeble Sportster, that’s just not the case. Yes, the BMW 840i’s power figures seem somewhat meek when seen with the segment standards, but the ride’s peak horsepower and peak torque, both kick in much earlier than that of the competitors, thus allowing it to catch-up with the other rides.

The BMW 840i Convertible can propel from 0-60 MPH in 5.0 seconds and can cover the quarter of a mile distance in 13.4 seconds, at a speed of 106 mph. The BMW 840i’s convertible can achieve a top speed of 155 mph, however, it is electronically capped at 130 mph.

The BMW 840i Convertible does a pretty good job of compensating for its power figure complexes, by exhibiting great off-the-line capabilities. However, the Bimmer lags behind the competitors, but not that much as one would expect after seeing the power difference. The Porsche 911 Carrera Cabriolet comes out as the fastest car of the segment with a 0-60 dash time of 4.2 seconds. The Jaguar F-TYPE rakes in the second sport, with 4.8 seconds 0-60 sprint time. Mercedes, making a close chase finishes in at 4.9 seconds, followed by the BMW 840i.

What about the braking performance of the BMW 8 Series convertible?

We do not yet know the exact figures for the BMW 840i’s brake rotor, but what we do know, is that the Bavarians have backed this aspect of their latest ambition with a wide array of high-tech features.

Apologies for the sheer absence of relevant information in the above-stated comparison table, but can’t help it (getting peanuts for salary *sigh*). However, what is evident from this comparison is that despite being the heaviest car of the lot, the BMW 840i portrays ultimate excellence with its halting performance.

What about its driving dynamics?

Think of a massive inline-6 engine, delivering tremendous power on tap. Think of a sleek-shifting 8-speed transmission. Think of ultra-smooth aerodynamics, working their way out as your car attacks those corners in and out. Impressive, right? Now combine all of those elements, stir the mix well, and the final product you’ll end up with is fondly called the 2020 BMW 8-series.

2020 BMW M840i Convertible Front View

The 840i Convertible is heck fast, though not as rapid as the M-spec models, yet fast enough to devastate other cars on a freeway. The BMW 840i starts a chain of reactions as soon as you hit that pedal with your right foot. First of all, is the engine that becomes hyper-active upon accelerating, making the ride slingshot to the sky (and trust us, with the top down, it really feels like shooting for the stars). In this process of catapulting itself, the 8-series cars give out an immensely pleasurable exhaust note, that can give a boo-boo to all the engine-lusters out there.

The 840i’s slippery aerodynamics does a commendable job as well, making this roadster move in and out of corners with utmost domination. The BMW 840i can be driven in 3 modes - comfort, Sport, and the deadly Sport+. While the Sport mode expedites to the destination with pops and cracks, driving around the town in comfort mode, is going to garnish you with sophistication.

8.0/10

The BMW 840i Convertible is going to drive you around the town with a lot of glamour and on the freeways, it is an absolute rocket, but that doesn’t mean that this lady is going to burn a hole in your pocket, with its fuel-demands.

The BMW 840i Convertible churns out a city mpg figure of 22 and a highway mpg figure of 29. Combining these figures, we get a combined mpg of 24, which happens to be a worthy digit for a ride, going from 0-60 in dot 5 seconds.

The BMW 840i offers the best in class fuel-efficiency, with a combined mpg of 24. The Jaguar F-TYPE and the Mercedes-Benz SL 450 Cabriolet, making a close chase, end up with 22 combined mpg. Finally lands the Porsche 911 Carrera Cabriolet with a combined mpg figure of 20. Porsche’s low mpg figures, when combined with a petite fuel-tank, results in the shortest range on offer in this segment.

2020 BMW 8 Series Convertible Interior

9.0/10

The BMW 840i convertible’s cabin is a cozy place to be in, where the several marks of luxury simply blend with the aggressive stance of the cabin to formulate the interior of this hottest intent of the Bavarians.

Starting with the front row, there is ample space in all directions for the occupants. Every 8-Series model brings on offer 14-way power-adjustable heated front seats which are aptly stuffed and feature just enough bolstering to hold you in place while swishing past those corners, without coming in your way of getting in or out of the car.

Speaking of the back seats, though the company claims that it has a passenger capacity of 4, yet the rear seats do not seem very warm and welcoming. The rear seats of the BMW 840i Convertible can accommodate children, but thinking of hosting 2 adults on the rear-seats makes you more of a satan.
