Shopping for a convertible is often equated with high expectations. Loaded with standard equipment, high-style interiors, and a convertible roof, the BMW Series 8 series is sure to meet your requirements. The 840i base model is a great fit for those who like to explore new avenues during long weekends. The average warranty package covers four years or 50,000 miles. However, it also covers three years of maintenance, setting the 8 series cars apart from the others in its class.

Performance
The 840i base model of the BMW 8 series is loaded with a 335- hp turbocharged six-cylinder engine that promises power and smooth shifts. It has an eight-speed automatic transmission system that contributes to the lightning-fast reaction of the car. The braking performance of this car is just as impressive. There are a couple of problems you might come across with the tight steering, but it is compensated with the overall delivery of the vehicle’s performance. Starting at $94,400, the series is a satisfying purchase.

Comfort
If you are looking for a classy, comfortable ride, this just might be it for you. The BMW 8 series 840i convertible is great at making up for the bumps across the road without jostling the occupants. The cabin is also among the quietest you can expect in this class of vehicles, making it a perfect fit for longer drives. Climate control, seat ventilation, heated seats, and air conditioning are all features that add to the experience.

Interior
The 840i convertible’s cabin is impressive to look at. The control panels are well placed and do not divulge the attention of the driver from the road to operate. While the front seats are comfortable, the rear ones are more fitting for children than adults. The adjustability on the front seats makes it easy to customize it to one’s need and find a comfortable position. Visibility is a little compromised, but the surround-view camera and blind spot monitoring system can help the driver to reach the destination hassle-free.

Infotainment
The standard audio system in the BMW 8 Series 840i car is stellar as it is, but if you wish to, you can choose to upgrade to a Bowers and Wilkins system. It can be useful for a quality music experience when driving. The infotainment system has a decent-quality touchscreen with great display quality and a responsive screen. It has easy-to-navigate features and can even be operated with voice commands. Since the system is cloud-based, it can be comparatively slower to respond.

Storage
When it comes to the storage space in a convertible, it is tough to be satisfied. The collapsible roof almost takes away some of the useful space, restricting the storage space. However, considering the size of this car, we did not anticipate being disappointed with the trunk space. With the roof up, you get to make use of 12.4 cubic feet of storage space, which can be narrowly extended by folding down the rear seats. However, if you want to roll the top down, there is little you can fit in there aside from a couple of grocery bags or a backpack.
On the inside, the door pockets offer ample storage for both driver and the front-row passenger. Car seats can be hooked up with the help of anchors on the rear seats, but they might not be as comfortable as you would hope for.
Gas mileage
The fuel economy for the 840i convertible is estimated by the EPA to be 22 mpg within city limits and 29 on the highway. This brings the average EPA estimate to 24 mpg combined. Compared to most of its competitors, the mileage statistics are better, making it more budget and environment-friendly. Of course, these numbers are on paper, and there can be a difference when the vehicle hits the road.
