Quick answer: The 2023 BMW 8 Series is a flagship luxury tourer originally priced from $85,000 for the Gran Coupe up to $143,700 for the M8 Competition Convertible. In 2026, severe depreciation makes used models highly attractive, with 840i resale values starting near $48,727. It offers exceptional performance via inline-six and twin-turbo V8 engines, though buyers must watch for V8 maintenance costs.
Key takeaways:
The 2023 BMW 8 Series originally debuted with a starting MSRP of $85,000 for the Gran Coupe, rising to $112,100 for the M850i Convertible. In 2026, typical used resale prices have depreciated significantly, with base 840i models averaging $48,727 and high-end trims trading around $69,662.
When first launched in the United States, the 2023 vehicle line represented the absolute pinnacle of BMW luxury and sports performance. Original pricing started at $85,000 for the entry-level 840i Gran Coupe. Choosing the classic two-door Coupe configuration bumped the base MSRP to $87,500, while the Convertible demanded a substantial premium, starting at $97,100. Adding BMW's xDrive all-wheel-drive system added $2,900 to the price of any 840i trim. Stepping up to the high-performance V8 models required a massive budget, with the M850i xDrive Coupe priced at $102,500 and the M850i xDrive Convertible reaching $112,100.
Fast forward to 2026, and the used market paints a very different picture. Flagship German luxury cars are notorious for steep depreciation curves, and the G15-generation 8 Series is no exception. Three years of ownership have eroded approximately 30% to 40% of the vehicle's original retail value. A used base 2023 BMW 840i Coupe that originally cost $87,500 now trades for an average of $48,727 in the used market. High-performance V8 variants, such as the M850i xDrive, have experienced even steeper dollar-amount declines, with typical used resale prices now hovering around $60,800. For smart used car shoppers in 2026, this depreciation presents an extraordinary opportunity to acquire a flagship grand tourer at the price of a mid-tier executive sedan.
| Trim Level | Body Style | Drivetrain | Original starting MSRP (USA) | Average 2026 Used Resale Value |
|---|---|---|---|---|
| 840i Gran Coupe | 4-Door Gran Coupe | RWD | $85,000 | $47,600 |
| 840i Coupe | 2-Door Coupe | RWD | $87,500 | $48,727 |
| 840i Convertible | 2-Door Convertible | RWD | $97,100 | $55,200 |
| 840i xDrive Coupe | 2-Door Coupe | AWD | $90,400 | $50,516 |
| M850i xDrive Gran Coupe | 4-Door Gran Coupe | AWD | $100,000 | $59,000 |
| M850i xDrive Coupe | 2-Door Coupe | AWD | $102,500 | $60,800 |
| M850i xDrive Convertible | 2-Door Convertible | AWD | $112,100 | $66,652 |
| M8 Competition Coupe | 2-Door Coupe | AWD | $134,100 | $78,500 |

The 2023 BMW 8 Series specs offer three distinct engine options: a 335-horsepower 3.0-liter turbocharged inline-six (B58) in 840i models, a 523-horsepower 4.4-liter twin-turbo V8 (N63) in M850i trims, and a 617-horsepower V8 (S63) in the M8 Competition.
At the heart of the base 840i models lies BMW's highly acclaimed B58 engine. This 3.0-liter turbocharged inline-six is widely regarded by automotive enthusiasts and mechanics as one of the most reliable modern powertrains in production. Generating 335 horsepower and 368 lb-ft of torque, it propels the rear-wheel-drive 840i Coupe from 0 to 60 mph in a swift 4.7 seconds. For most drivers, this engine offers a perfect balance of smooth power delivery, decent fuel economy (up to 29 MPG highway), and lower long-term maintenance costs.
For those seeking traditional American muscle performance wrapped in a German luxury suit, the M850i xDrive steps up to the N63 4.4-liter twin-turbo V8 engine. Delivering 523 horsepower and 553 lb-ft of torque, this V8 works in perfect tandem with standard xDrive all-wheel drive and a quick-shifting eight-speed automatic transmission. The result is a blistering 0 to 60 mph time of just 3.6 seconds, accompanied by a deep V8 exhaust note. However, this performance comes with a trade-off at the gas pump, with EPA fuel economy dropping to an estimated 17 MPG city and 24 MPG highway.
At the top of the performance hierarchy sits the track-focused M8 Competition, featuring the S63 V8 engine tuned to produce 617 horsepower. This flagship powerhouse reduces the 0 to 60 mph sprint to an astonishing 3.0 seconds, making it competitive with dedicated supercars.
| Engine Code | Engine Type | Horsepower | Torque (lb-ft) | 0-60 mph (sec) | EPA fuel economy (City/HWY/Combined MPG) | Trim Level |
|---|---|---|---|---|---|---|
| B58 | 3.0L Turbocharged Inline-6 | 335 hp | 368 lb-ft | 4.7 sec | 21 / 29 / 24 MPG | 840i RWD |
| N63 | 4.4L Twin-Turbocharged V8 | 523 hp | 553 lb-ft | 3.6 sec | 17 / 24 / 19 MPG | M850i xDrive |
| S63 | 4.4L Twin-Turbocharged V8 | 617 hp | 553 lb-ft | 3.0 sec | 15 / 22 / 17 MPG | M8 Competition |
The 2023 BMW 8 Series is available in Coupe, Convertible, and Gran Coupe layouts. While the two-door Coupe and Convertible seat four passengers with up to 14.8 cubic feet of cargo space, the four-door Gran Coupe provides seating for five and 15.5 cubic feet.
Choosing the right body style for the 8 Series is critical, as each format serves a different target audience. The two-door Coupe is the styling leader, presenting a classic low-slung grand touring silhouette. However, the Coupe's sloping roofline severely restricts rear-seat headroom and legroom, making the back seats suitable only for small children or luggage. The Coupe offers a generous 14.8 cubic feet of trunk space, which is highly practical for long road trips.
The Convertible version replaces the metal roof with an electrically operated multi-layer fabric top that can open or close in just 15 seconds at speeds up to 30 mph. While open-top cruising is delightful, the folding roof mechanism encroaches on cargo space, reducing total trunk capacity to 12.4 cubic feet. The rear seats also feel slightly more cramped due to the packaging requirements of the convertible top.
For buyers who need to carry adults in the back seat regularly, the four-door Gran Coupe is the clear choice. It features a wheelbase that is 7.9 inches longer than the two-door models, translating directly into adult-friendly rear legroom. It is also the only variant configured to seat five passengers. Despite the four-door utility, the Gran Coupe retains a sleek coupe-like roofline and offers the largest trunk in the lineup at 15.5 cubic feet.
BMW loaded the 2023 8 Series with a wealth of standard luxury and technology features. For the 2023 model year, the center infotainment display received a major upgrade, growing from 10.25 inches to a generous 12.3-inch screen. This display runs BMW's iDrive 7 system, which supports wireless Apple CarPlay and Android Auto integration. Standard equipment across all trims includes a 12.3-inch digital gauge cluster, a head-up display, and wireless smartphone charging.
The interior materials are exceptionally premium, featuring standard Merino leather upholstery, a leather-wrapped dashboard, and ambient lighting. Sound is delivered through a standard 16-speaker Harman Kardon premium audio system, though buyers in the used market should look out for models equipped with the optional 1,400-watt Bowers & Wilkins Diamond Surround Sound system. Performance-enhancing standard features include adaptive M suspension, M Sport brakes, and an M Sport differential, ensuring that even base models handle with athletic composure.
The 2023 BMW 8 Series competes directly with the Lexus LC 500 and the Porsche 911 Carrera. While the 8 Series offers superior cargo space and lower used acquisition costs in 2026, the LC 500 and 911 offer better depreciation protection.
When compared to the Lexus LC 500, the BMW M850i xDrive Coupe offers much more explosive acceleration. The Lexus LC 500 uses a naturally aspirated 5.0-liter V8 engine producing 471 horsepower and 398 lb-ft of torque. While the LC 500 cannot match the twin-turbocharged low-end torque of the BMW V8, the Lexus engine delivers a glorious high-rpm sound signature and has earned an outstanding reputation for long-term reliability. In terms of styling, the LC 500 looks like a concept car brought to life, which has helped it maintain far stronger resale values. In 2026, a used 2023 Lexus LC 500 Coupe still commands around $73,500, which is significantly higher than a used M850i Coupe.
The Porsche 911 Carrera operates on a different dynamic level. It is a dedicated sports car rather than a heavy grand tourer. Powered by a 379-horsepower twin-turbo flat-six, the base 911 Carrera handles with a level of precision and driver connection that the heavier BMW 8 Series simply cannot match. However, the Porsche is far less practical, with a tiny front trunk measuring just 4.6 cubic feet and a much firmer ride quality. The Porsche 911 also boasts legendary value retention. A used 2023 Porsche 911 Carrera in 2026 still sells for around $91,000, retaining roughly 86% of its original MSRP.
| Parameter | 2023 BMW M850i xDrive Coupe | 2023 Lexus LC 500 Coupe | 2023 Porsche 911 Carrera |
|---|---|---|---|
| Engine Type | 4.4L Twin-Turbo V8 | 5.0L Naturally Aspirated V8 | 3.0L Twin-Turbo Flat-6 |
| Power Output | 523 hp | 471 hp | 379 hp |
| Torque | 553 lb-ft | 398 lb-ft | 331 lb-ft |
| Drivetrain | AWD | RWD | RWD |
| 0-60 mph acceleration | 3.6 seconds | 4.4 seconds | 4.0 seconds |
| Trunk Volume | 14.8 cubic feet | 5.4 cubic feet | 4.6 cubic feet (front trunk) |
| Original Base MSRP | $102,500 | $94,450 | $106,100 |
| Average 2026 Used Value | $60,800 (approx. 59% retained) | $73,500 (approx. 78% retained) | $91,000 (approx. 86% retained) |
The 2023 BMW 8 Series represents a massive depreciation trap for original buyers, losing 30-40% of its value in three years. However, this steep drop makes it an exceptional bargain in the 2026 used market for performance car shoppers.
To understand the unique value proposition of the 2023 BMW 8 Series in 2026, one must analyze the depreciation curve. German executive tourers suffer from high initial leasing rates and a pool of buyers who demand the absolute newest models. Once the original warranty nears its expiration after four years, values plummet. In 2026, original owners who paid $90,000 to $110,000 for their vehicles have taken a massive financial hit.
For used buyers, this is a golden opportunity. By purchasing a used 2023 model, you let the first owner absorb the steepest part of the depreciation curve. You gain access to 95% of the technology, performance, and luxury of a brand-new model for almost half the price.
However, buying a used BMW requires strategy. The B58 inline-six engine in the 840i is highly recommended for used buyers. It has proven to be incredibly robust and is much cheaper to maintain than the complex V8 engines. The V8-powered M850i is tempting, but the N63 engine has a history of high heat generation and potential oil consumption, making thorough service records mandatory.
Expert view: Buying a used 2023 840i in 2026 is highly recommended for drivers seeking flagship comfort at a 40% discount, as the B58 engine is legendary for reliability, but buyers seeking track agility should look toward a Porsche 911.
The 2023 BMW 8 Series achieves solid general reliability, yet used buyers must verify recall status. The NHTSA has issued recalls for EGR cooler coolant leaks, brake connection faults, and curtain airbag deployment concerns.
According to long-term reliability tracking from publications like What Car?, the G15-generation 8 Series ranks well in the sports coupe segment. However, used luxury cars feature complex electrical systems that can develop glitches as they age. Owners have reported occasional issues with the gesture control sensors, wireless charging pad overheating, and software bugs in the iDrive infotainment system.
More importantly, used buyers must verify that all active safety recalls have been resolved. There are four primary recall campaigns affecting the 2023 model year:
To ensure peace of mind, used buyers should always obtain a pre-purchase inspection from a certified technician and verify the vehicle's VIN against the NHTSA recall database to ensure all repairs were carried out by a dealership.
Note: Always run a VIN check on the NHTSA database to confirm that the brake cylinder and EGR cooler recalls have been completed by an authorized BMW service center before completing a used purchase.
As buyers look at their options, they may also consider how this model compares to the updated 2024 BMW 8 Series or the newer 2025 BMW 8 Series review to see if the minor changes in later years justify the extra cost. To browse all available models and trims, buyers can explore the broader BMW 8 Series hub.
The primary difference lies in the engine and standard features. The 840i uses a 3.0-liter turbocharged inline-six engine with 335 horsepower and is available in rear-wheel or all-wheel drive, while the M850i features a standard 4.4-liter twin-turbo V8 engine producing 523 horsepower and standard xDrive.
Yes, the 2023 BMW 8 Series offers a V8 engine in the M850i, Alpina B8, and M8 Competition configurations, which all feature a 4.4-liter twin-turbo V8 producing between 523 and 617 horsepower.
BMW has not officially discontinued the 8 Series, but reports suggest the flagship grand tourer line will transition or merge into the next-generation luxury lineup, making the 2023-2026 models the last pure internal combustion models.
In 2026, a used 2023 BMW 8 Series costs between $48,727 and $69,662 on average, representing a significant price drop from its original base MSRP range of $85,000 to $112,100.
