2026 BMW 8 Series Convertible: Luxury and Performance in Farewell

The 2026 BMW 8 Series Convertible arrives on the market with a special status: it is the last iteration of the current generation (G14). This luxury grand tourer combines refined performance, high-level comfort, and advanced technology, positioning itself as a distinct option for those seeking a sophisticated outdoor driving experience.

Based on the latest technical data obtained from reliable sources in the United States, Brazil, China, and Japan, I have prepared this comprehensive analysis for you to understand everything about this farewell icon. Let’s dive into the details that make the 8 Series Convertible a remarkable car.

A Farewell Icon: The 2026 BMW 8 Series Convertible

The news for 2026 does not bring major revolutions, but rather the confirmation of the end of a cycle. Production of the G14/G15/G16 lineup (which includes the Convertible, Coupe, and Gran Coupe) is set to conclude in April 2026, marking the exit of this elegant BMW family.

Updates for this final model year are minor, primarily focusing on software refinements for the iDrive 7 infotainment system and small improvements in active safety features. Don’t expect significant visual or mechanical changes; the 2026 8 Series Convertible retains the essence that defined it in recent years.

Versions for Every Taste (and Wallet)

The 2026 8 Series Convertible is offered in four distinct configurations, each catering to a different buyer profile. From the elegantly balanced 840i to the raw power of the M8 Competition, there’s an option for varying priorities within the luxury segment.

840i Convertible

This is the gateway to the world of the 8 Series Convertible. Equipped with a six-cylinder inline engine, it offers a harmonious blend of performance and efficiency. It’s the perfect choice for those who value smooth cruising and classic drivability with rear-wheel drive.

• Engine: 3.0L TwinPower Turbo inline 6-cylinder
• Power: 335 hp @ 5,000-6,500 rpm
• Torque: 369 lb-ft @ 1,600-4,500 rpm
• Transmission: 8-speed Sport Automatic with paddle shifters
• Drive: Rear-wheel drive (RWD)

• Top Speed: 155 mph (electronically limited)
• Combined Fuel Economy (EPA/WLTP Estimate): 26 mpg (9.0 L/100 km)
• Weight: 4,475 lb (2,030 kg)

840i xDrive Convertible

For those seeking more security and performance in varying weather conditions, the xDrive version adds BMW’s acclaimed all-wheel drive. This translates to slightly faster acceleration and greater confidence on low-grip surfaces.

• Differences from the 840i:
• Drive: All-wheel drive (xDrive)
• 0-60 mph: 4.6 seconds
• Weight: 4,608 lb (2,090 kg, +133 lb)

M850i xDrive Convertible

Stepping up a level, we find the M850i xDrive, a true luxury “muscle car” disguised in a sleek suit. The V8 engine delivers impressive performance and an addictive growl, complemented by M Sport tuning on the suspension and brakes.

• Engine: 4.4L M TwinPower Turbo V8
• Power: 523 hp @ 5,500-6,000 rpm
• Torque: 553 lb-ft @ 1,800-4,600 rpm
• Transmission: 8-speed M Sport Automatic with Drivelogic
• Drive: All-wheel drive (xDrive)
• 0-60 mph: 3.9 seconds
• Top Speed: 155 mph (190 mph with optional M Driver’s Package)
• Combined Fuel Economy: 20 mpg (11.8 L/100 km)
• Weight: 4,608 lb (2,090 kg)
• Exclusive Features: 20-inch M wheels, M Sport brakes, M adaptive suspension.

M8 Competition Convertible

At the top of the food chain is the M8 Competition. This version focuses on extracting the maximum performance from the 8 Series chassis, with even more power, more aggressive suspension tuning, and dedicated components from the M division. It’s a car for those who refuse to forego excitement behind the wheel, even in a luxury convertible.

The BMW M division continues to innovate, even exploring the future of performance with concepts like the BMW M3 Electric. This shows the brand’s commitment to adapting its performance philosophy for the era of electrification.

• Engine: 4.4L M TwinPower Turbo V8
• Power: 617 hp @ 6,000 rpm
• Torque: 553 lb-ft @ 1,800-5,700 rpm
• Transmission: 8-speed M Sport Automatic with Drivelogic
• Drive: All-wheel drive (xDrive, with 2WD mode)
• 0-60 mph: 3.1 seconds
• Top Speed: 155 mph (190 mph with M Driver’s Package)
• Combined Fuel Economy: 17 mpg (13.8 L/100 km)
• Weight: 4,700 lb (2,132 kg)
• Exclusive Features: Lightweight noise-reducing soft top, M Compound brakes, M-specific finishes.

What’s Changed (Or Not) in 2026

As I mentioned, 2026 is a maintenance year for the 8 Series Convertible. The major updates are subtle:

• Software updates for the iDrive 7 system, promising a slightly more responsive interface.
• Improvements in acoustic insulation of the soft top, seeking an even quieter environment with the roof closed.
• Enhanced integration with the My BMW app, including the remote engine start feature that has become standard in recent years, as highlighted by sources like Kelley Blue Book.

Compared to models from 2019 to 2024, the 8 Series already featured the active driving assistant as standard and a light visual update with illuminated grille and Laserlight headlights.

Head-to-Head: 8 Series vs. Heavyweight Rivals

The BMW 8 Series Convertible competes in a luxury segment where style, performance, and exclusivity are paramount. Its main rivals offer slightly different approaches.

Quick Comparison

Feature	BMW M850i xDrive	Mercedes-Benz SL 55 AMG	Porsche 911 Carrera S Cabriolet
Price (US, approx.)	$117,175 USD	$141,300 USD	$133,400 USD
Engine	V8 4.4L Turbo	V8 4.0L Biturbo	Flat-6 3.0L Turbo
Power	523 hp	469 hp	443 hp
0-60 mph	3.9 seconds	3.8 seconds	3.5 seconds
Trunk Space (top up)	350 L	Not specified	133 L

The Mercedes-Benz SL-Class, especially in the SL 55 AMG version, offers a more eye-catching design and an interior that many consider superior in terms of materials and finish. However, it tends to be more expensive in the comparable version and, according to reviews, is less agile in corners than the M versions of the 8 Series.

On the other hand, the Porsche 911 Cabriolet, an eternal icon, stands out for its sharp handling and resale value. Its drawback is the tiny trunk and an interior that is less focused on luxury and more on pure performance.

Meanwhile, BMW has been exploring other avenues in the luxury market, such as the BMW iX xDrive60 2025, showcasing its diversification into cutting-edge electric SUVs.

Competitors like the Mercedes CLA, although in a different category, also indicate the movement of luxury brands towards electrification, something the current 8 Series does not offer.

Pros and Cons: The Balancing Act of Luxury and Performance

Pros

• Comfort: Exceptionally smooth and quiet ride, ideal for long journeys.
• Performance: Vigorous acceleration across all versions, spectacular in the M850i and M8.
• Technology: Intuitive iDrive 7 system, full smartphone integration, and remote features.
• Finish: High-quality materials and attention to detail in the interior.
• Space: Good front passenger space and decent trunk capacity for a convertible (with the top closed).

Cons

• Cost: High price point, especially for high-performance M versions.
• Maintenance: Maintenance costs and parts are typical of a luxury BMW, meaning they are high.
• Rear Space: The rear seats are somewhat symbolic, serving more for extra luggage than for adult passengers.
• Handling: The steering, while precise, lacks some of the visceral feedback found in rivals more focused on pure sportiness like the 911.

Real-World Prices (and Why They Vary So Much)

Prices for the 2026 BMW 8 Series Convertible vary significantly between markets, even after conversion to US Dollars (using rates from April 24, 2025). Let’s look at some examples:

Estimated Prices (USD)

Version	USA	Brazil (approx.)	China (approx.)	Japan (approx.)
840i	$101,400	$123,500	$126,000	$92,400
840i xDrive	$104,400	$129,200	$133,000	$95,700
M850i xDrive	$117,175	$152,000	$154,000	$108,900
M8 Competition	$149,400	$199,500	$196,000	$138,600

It is noteworthy how prices in Brazil and China are considerably higher than in the US and Japan. This largely reflects the tax burden on luxury goods and specific import duties in those markets. Japanese sources, on the other hand, suggest slightly lower prices, possibly due to local incentives or differences in standard equipment.

The information from the US, with detailed reports from agencies like the EPA for fuel consumption and alignment with official communications from BMW USA, is generally considered the most consistent and reliable for global specifications.
