Used BMW M8 Gran Coupe Review: Power, Value, and Reliability

Used BMW M8 Gran Coupe Review: Power, Value, and Reliability

If you’ve ever thought a supercar can’t be practical, the M8 Gran Coupe is here to shatter that myth—beautifully. With the speed of a coupe, the comfort of a sedan, and the attitude of a German rock star, this is the kind of luxury machine that looks just as good pulling up to valet as it does dominating the open highway. And if you’re looking for the smartest way to own one? Buying used might just be your winning move.

Let’s dive into what makes the M8 Gran Coupe such a knockout—and why scoring a used one might be your best automotive decision yet.

We’ve already broken down the coupe and convertible in The Used BMW M8 Competition – Where Luxury Meets Motorsport DNA, and if you’re into the brand’s roots, Unveiling the History of BMW at AutoPro Nashville covers that too.

The M8 Gran Coupe Story: Power Meets Practicality

BMW’s M8 Gran Coupe didn’t just show up to compete—it arrived to dominate, merging high-performance engineering with the space and comfort of a grand touring sedan. Let’s take a closer look at how it came to life and evolved since its debut.

Origins: From Concept to Reality

The idea of the M8 Gran Coupe took shape after BMW relaunched the 8 Series lineup in 2018. With the return of this premium grand tourer, BMW aimed to offer something more exclusive than the 7 Series and sharper than the 5 Series—without skimping on luxury or performance.

Soon after, BMW announced it would unleash full M versions across all 8 Series body styles. While the M8 Coupe and Convertible debuted in 2019, the M8 Gran Coupe followed in 2020, bringing more versatility with four doors and a stretched wheelbase.

This wasn’t just a longer M8—it was built with its own chassis tuning, unique proportions, and the same aggressive heart under the hood.

2020: The Debut Year

Launch of the M8 four-door and M8 Competition Gran Coupe
First time BMW offered a true four-door “M” flagship in the 8 Series line
Powered by the 4.4L twin-turbo V8 with 600 hp (617 hp in Competition)
M xDrive AWD system with rear-wheel bias
Adaptive M suspension and standard carbon fiber roof on Competition
Design differences from the Coupe included a longer wheelbase and unique rear door styling for easier rear access

This model year set the tone for the M8 GC’s blend of explosive power and high-end luxury. Reviewers immediately noted it felt more refined than an M5 and more planted than its two-door sibling.

2021: Subtle Refinements

Technology upgrades included over-the-air updates and improved iDrive 7 responsiveness
Enhanced interior customization options: new trim colors, contrast stitching, and seat finishes
Standard features were expanded in some trims—soft-close doors and more driver-assist features became more widely available

While performance stayed the same, BMW focused on comfort and tech polish, showing their intention to make the M8 GC a true luxury flagship, not just a track monster with back seats.

2022: Continuation with Expanded Colors and Packages

No major mechanical changes, but BMW added more special paint finishes, including Frozen Pure Grey and Tanzanite Blue II
Wider availability of M Carbon exterior package, which added lightweight visual flair
Optional M Driver’s Package with a higher top speed limiter and access to BMW M driving school

BMW recognized its audience wanted more personalization—and this year offered just that.

2023–2024: Mild Facelift and Tech Updates

Subtle design tweaks to headlights and front grille
Introduction of BMW Curved Display, merging digital gauge cluster and infotainment under a single curved screen
Improved voice control and Apple CarPlay/Android Auto integration
Continued offering of M8 Competition Gran Coupe as the sole model in many markets—dropping the base M8 in some regions

This mid-cycle refresh modernized the cockpit while keeping the driving dynamics intact. Enthusiasts welcomed the upgraded interior layout and seamless tech interface.

2025 and Beyond: What’s Next?

As of now, the M8 Gran Coupe remains a powerhouse in BMW’s M lineup with no confirmed redesign—but with BMW’s electric future accelerating, we could see a hybrid or fully electric version in the next generation. Until then, the current M8 GC continues to blend muscle, luxury, and everyday usability in a way few competitors can.

Specs, Features & Trims of The Four-Door M8

The 2023–2024 BMW M8 sedan might just be one of the most underappreciated monsters on the road. It’s sleek enough to pass for a high-end executive cruiser—but tap the throttle, and you’ll hear the growl of a supercar that forgot it had four doors. This thing doesn’t just blur the line between track and touring—it eats the line for breakfast.

2023–2024 BMW M8 Gran Coupe: A Closer Look at the Numbers

BMW didn’t mess too much with a good thing here, and honestly, we’re glad. The 2023 and 2024 M8 Gran Coupe models remain mechanical twins to their predecessors—refined, ridiculously fast, and tech-forward.

Here’s what you get under the hood:

Engine: 4.4L Twin-Turbo V8
Horsepower: 617 hp (Competition trim standard)
Torque: 553 lb-ft
0–60 mph: ~3.0 seconds
Transmission: 8-speed M Steptronic automatic
Drivetrain: M xDrive AWD with rear-wheel-drive mode
Top Speed: 155 mph (190+ with M Driver’s Package)

The real magic is how all of this power feels—delivered smoothly, but with the authority of a car that knows it can smoke almost anything on the highway.

Interior & Tech: Not Just a Pretty Face

In 2023, BMW gave the M8 Gran Coupe its most noticeable cabin update—introducing the BMW Curved Display, which combines a massive digital instrument cluster with a large infotainment screen in a seamless arc. It’s futuristic, sharp, and remarkably intuitive.

Depending on the trim and options, here’s what else you’ll enjoy:

Merino leather in nearly every imaginable color
M Carbon bucket seats (optional, if you’re brave)
Heated, ventilated, and massaging front seats
Bowers & Wilkins Diamond surround sound system (optional and worth it)
Ambient lighting, wireless charging, and multi-zone climate control
Safety tech like adaptive cruise control, lane-keep assist, and parking sensors

Let’s not forget the four-door advantage: actual legroom for rear passengers, making this one of the few cars that can scare your friends and keep them comfortable.

Trim Breakdown: Know What You’re Getting

Unlike some models that offer endless trims and confusing bundles, the M8 Gran Coupe keeps it simple:

M8 Gran Coupe (Discontinued in many markets) – Originally the base model with 600 hp
M8 Competition Gran Coupe – Standard now, with all the best performance features baked in

The Competition model comes with:

Enhanced exhaust sound tuning
Tighter suspension
Exclusive wheels and badging
M Sport seats and extra performance settings

If you find a used M8 Gran Coupe in Competition spec, you’re already winning.

2025 BMW M8 Gran Coupe: What’s New?

So, what about the 2025 model?

Well… not much. As of now, BMW hasn’t announced any major mechanical upgrades or visual refreshes for 2025. The same 617-horsepower engine carries over, and trim offerings are expected to stay consistent, with the M8 Competition Gran Coupe remaining the default configuration in most markets.

A Quick Personal Take (No Sides, Just Truth)

There’s something about driving through Brentwood on a crisp Saturday morning that makes the BMW’s high-performance sedan feel right at home. I remember cruising down Franklin Road near Crockett Park in a 2023 model—sun peeking out, engine barely ticking over in Comfort mode. Even with all its power, the car felt composed, elegant… like it belonged in this part of Tennessee.

But then, I switched it to Sport Plus and took the long way down Murray Lane. The exhaust came alive, the steering tightened, and suddenly Brentwood’s quiet backroads felt like a test track. That’s the dual nature of the M8 Gran Coupe—it can be calm and luxurious when you’re pulling into your favorite coffee shop in town, but with one tap, it turns into a beast on wheels.

Buying Guide & Competitive Analysis

Buying a high-performance luxury car like the BMW M8 Gran Coupe is a big decision—not just because of the price, but because of the long-term ownership experience. Whether you’re looking at a lightly used 2023 or 2024 model or weighing it against rivals like the Mercedes-AMG GT 63, Audi RS7, or Porsche Panamera Turbo, this guide will walk you through what matters most: reliability, performance, comfort, and cost of ownership.

Common Issues to Know Before You Buy

Even a car built by BMW M isn’t immune to problems, especially when buying used. Thankfully, the M8 Gran Coupe has proven to be relatively solid—especially 2023 and newer models. That said, here are some things to keep in mind:

Brake wear: The M8’s performance brakes are fantastic but expensive to replace. If the previous owner drove aggressively, they could wear out quickly.
Tire and wheel damage: With 20-inch wheels and low-profile tires, curb rash and sidewall bubbles aren’t uncommon—especially in urban areas.
Oil consumption: Some owners have reported slightly higher oil use in earlier years. This is common with high-performance turbo engines but should be monitored.
Software glitches: iDrive 7 and the Curved Display system in 2023–2024 models are generally reliable, but occasional bugs or Bluetooth issues can occur. These are usually fixed by BMW updates.

A pre-purchase inspection (PPI) is a smart move. Even though BMW builds these to last, knowing what you’re walking into makes a big difference with any pre-owned luxury vehicle.

Maintenance Tips for Long-Term Ownership

Use premium fuel only. The twin-turbo V8 is designed for it, and running anything less can affect performance and engine life.
Stick to regular oil changes. Every 5,000–7,500 miles, even if BMW recommends longer intervals (10,000-mile). The engine runs hot and hard, so clean oil matters.
Flush the transmission and differential fluids around 50,000 miles, especially if the car has been driven spiritedly.
Inspect suspension components around 60,000 miles. Control arms and bushings can wear early on cars with stiffer setups like the M8.

If you’re buying from a dealer that offers extended warranties or certified service, that’s a big bonus. It helps offset the cost of ownership on high-performance cars like this.

How the M8 Gran Coupe Stacks Up Against the Competition

Let’s be honest: you’ve probably also looked at the Mercedes-AMG GT 63, the Audi RS7, or even a Porsche Panamera Turbo. They all offer similar price points, power figures, and luxury. Here’s how they compare in key areas:

Model	Performance	Comfort & Interior	Tech & Features	Reliability	Resale Value
BMW M8 Gran Coupe	Brutally quick, tight AWD control	Sporty yet refined, carbon trim options	iDrive 7, Curved Display, high customization	Solid post-2022	Moderate; improves if well-maintained
Mercedes-AMG GT 63	Explosive throttle, heavier feel	Plush and aggressive; AMG vibe	MBUX is powerful but takes time to learn	Reliable but complex electronics	Slightly higher resale
Audi RS7	More subtle, balanced driving feel	Sleek design, excellent build quality	Intuitive MMI, Audi Virtual Cockpit	Very reliable	One of the best in segment
Porsche Panamera Turbo	Sharper handling, more precision	Conservative interior but high-end	Clean interface, fewer gimmicks	High reliability if serviced properly	Strong resale value

Verdict? There’s no outright winner—each car suits a different kind of driver. The M8 Gran Coupe is the loudest in terms of styling and power delivery, while the RS7 is the most discreet daily weapon. Porsche wins on precision, and the AMG delivers brute character with plush comfort. Choose what fits your personality—and budget.

Best Years to Buy: Our Expert Pick

If you’re shopping used, 2023 and 2024 are your sweet spot. These models come with the updated Curved Display, polished tech, and standard Competition trim. They’ve also benefited from BMW ironing out small kinks from earlier production years. You get modern design, peak performance, and typically lower mileage—all without paying the new car premium.

Avoid the temptation to pay more for a 2025 unless it brings a meaningful update. As of now, the specs are unchanged from 2024.

Why Buying a Used M8 Gran Coupe Makes Sense

There’s no denying that a new car comes with that “just built” feeling—but with models like the M8 Competition Gran Coupe, depreciation hits fast and hard. That’s why smart buyers go used.

You could save $20,000–$30,000 compared to new, often for a car with under 10,000 miles.
Most 2023+ models are still under factory warranty or qualify for extended warranty options.
You get a fully loaded car—often with optional extras the first owner paid for.

How to Choose the Right Dealership for a High-Performance Car

Buying an M8 Gran Coupe isn’t just about the car—it’s about who you buy it from. A good dealership should:

Provide detailed vehicle history reports so you know the car’s background.
Offer test drives long enough to get a real feel for how the car handles.
Include warranty options or certified inspections, especially on high-performance models.
Be transparent about financing terms, trade-in values, and service support after purchase.

AutoPro Nashville is widely recognized for following these practices, which is why many enthusiasts trust them for high-end performance models like the M8 Gran Coupe.
