Test Drive

This review is based on my experience during a test drive. It reflects my first impressions behind the wheel rather than long-term ownership.

The BMW M850i occupies a unique place in BMW’s lineup. It’s not a full M car, yet it offers performance that rivals many dedicated sports cars while wrapping it all in a luxurious grand touring package.

Going into this test drive, I wasn’t expecting the M850i to surprise me.

As someone who daily drives a BMW M550i xDrive, I’m already very familiar with BMW’s 4.4-litre twin-turbo V8. On paper, the M850i uses a newer version of the same engine with a little more power, so I expected the driving experience to feel largely familiar.

I couldn’t have been more wrong.

From the moment I pulled away, it became obvious that this wasn’t simply a more powerful M550i. It felt like an entirely different beast.

First Impressions

Even before setting off, the M850i makes an impression.

The startup immediately lets you know you’re sitting in something special. This particular car was completely stock, yet the V8 produced a deep, refined growl that sounded incredible without ever feeling excessive. It wasn’t loud for the sake of being loud. It simply sounded like a proper performance car.

Once underway in Comfort mode, the character changed completely.

The M850i became calm, composed and incredibly smooth. The ride quality was excellent, the gearbox almost disappeared into the background, and the car felt perfectly suited for long-distance cruising. It was quiet, effortless and every bit as luxurious as you’d expect from BMW’s flagship coupe.

Behind the Wheel

Then came Sport mode.

This is where the M850i completely transformed.

Throttle response sharpened instantly, the gearbox became more aggressive, and the V8 came alive. The acceleration is nothing short of brutal. The amount of power the car delivers is simply insane, yet it never feels intimidating. It builds speed effortlessly, making every press of the throttle addictive.

Despite already owning a car with the same engine family, I was genuinely surprised by how different the M850i felt. It delivers its performance with a confidence that constantly reminds you you’re driving something special.

Comfort & Interior

What impressed me most was how well BMW balanced two completely different personalities.

In Comfort mode, it’s an exceptionally refined grand tourer. The ride is smooth, quiet and incredibly comfortable.

Switch to Sport, and it becomes an entirely different machine.

Very few cars manage to combine luxury and performance this well. It never asks you to compromise. Whether you’re cruising on the motorway or accelerating out of a corner, the M850i always feels composed and capable.

For me, that’s what makes this car so impressive. It isn’t just fast. It’s genuinely comfortable at the same time.

Design

The M850i is one of BMW’s most elegant modern coupes.

Its long bonnet, low roofline and muscular rear give it real presence without looking overstyled. It has an understated confidence that’s becoming increasingly rare.

Unlike many performance cars that try to grab attention with oversized vents and aggressive styling, the M850i feels mature. It doesn’t need to shout.

Things I Didn’t Like

It’s genuinely difficult to criticize the M850i after a short test drive.

If I had to point out one thing, it’s that the car can almost hide its own performance. In Comfort mode it’s so refined and composed that it’s easy to forget there’s a twin-turbo V8 waiting under your right foot.

That isn’t really a flaw. It simply highlights how successfully BMW has combined luxury and performance in one package.

Final Thoughts

I expected the M850i to feel like a slightly newer, slightly more powerful version of my own M550i.

Instead, I discovered a car with a completely different character.

The M850i isn’t simply about having more horsepower. It’s about how effortlessly it combines luxury, refinement and breathtaking performance into one package.

It cruises like a luxury coupe, sounds exactly as a V8 should, and accelerates with an authority that constantly reminds you you’re driving something special.

BMW didn’t just build a fast grand tourer.

They built one that makes every journey feel like an occasion.

Nordic Throttle Verdict

Would I drive it again?

Absolutely.

Pros

✓ Incredible V8 soundtrack

✓ Brutal yet effortless acceleration

✓ Outstanding comfort

✓ Premium interior

✓ Perfect balance of luxury and performance

✓ Elegant grand touring design

Cons

✗ None that stood out during my test drive.

The BMW M850i completely exceeded my expectations.

I expected familiarity.

Instead, I experienced a car that felt entirely different from the one I drive every day, despite sharing the same engine family.

It’s refined when you want it to be, exciting when you ask it to be, and somehow manages to combine comfort and performance without compromising either.

Some cars are driven.

Others are experienced.

The BMW M850i belongs in the second category.

Every car teaches you something. The C300e taught me that performance and efficiency don’t have to be opposites.

Stepping into the hybrid world was something completely new for me, and honestly, I wasn’t sure what to expect. The Mercedes-Benz C300e turned out to be a pleasant surprise, offering a driving experience that was both refined and surprisingly quick.

It wasn’t perfect, but it did exactly what it was designed to do.

What It Is

The C300e combines a 2.0-litre turbocharged petrol engine with an electric motor, producing a combined output of around 320 horsepower.

Those figures only tell half the story.

What really stands out is the instant response from the electric motor. The moment you press the accelerator, the car feels eager and effortless, making it noticeably quicker than you’d expect from a comfortable executive saloon. It never feels underpowered, whether you’re pulling away from traffic lights or overtaking on the motorway.

The Daily Feel

This was where the C300e impressed me the most.

My car was the pre-facelift model with the smaller battery, offering around 50 kilometres of electric range. For city driving, that proved to be more than enough. Most shorter journeys could be completed entirely on electric power, making daily driving both quiet and surprisingly economical.

Comfort was another area where the Mercedes excelled. The cabin was incredibly quiet, the seats were supportive, and every journey felt relaxed. Whether it was my daily commute or a longer road trip, the C300e always felt effortless to drive.

It wasn’t just me who noticed. Friends and family regularly commented on how comfortable the car was, especially during longer journeys.

Handling and Ride

The C300e was built with comfort in mind, and it shows.

The suspension absorbs poor road surfaces with ease, making motorway driving incredibly relaxing. It’s the kind of car that encourages you to settle into the seat and simply enjoy the journey.

That said, the extra battery weight does make itself known. At nearly 300 kilograms heavier than a standard petrol C-Class, the car feels noticeably heavier through corners. It remains composed and confidence-inspiring, but it doesn’t have the agility or sharpness of lighter rivals.

If you’re looking for a car to attack your favourite back road, this probably isn’t it.

If you’re looking for effortless comfort every single day, it’s difficult to fault.

Personal Note: Better Than Expected

I’ll admit it, I was sceptical before buying my first plug-in hybrid.

I wondered whether it would feel like a compromise. Too heavy to be fun, yet not efficient enough to justify the extra complexity.

Instead, it completely changed my opinion.

The instant electric torque made everyday driving effortless, while the combined 320 horsepower meant the car always had plenty of performance when I wanted it. It introduced me to hybrid driving in the best possible way and made me realise that efficiency doesn’t have to come at the expense of comfort or performance.

Like every car, it had its flaws.

The battery occupied a significant portion of the boot, creating a large hump that made loading luggage less practical than in a regular C-Class. Fuel consumption also became noticeably higher once the battery was depleted, largely due to the additional weight the petrol engine had to carry around.

Neither issue was enough to overshadow what the car did well.

Verdict

The Mercedes-Benz C300e won’t be remembered as the most exciting C-Class ever built.

What it offers instead is something many drivers will appreciate even more: a brilliant balance of luxury, performance and efficiency.

Yes, the boot space is compromised, and yes, you’ll notice the extra weight if you start pushing through corners.

But if you can charge it regularly and use it as intended, the C300e is an outstanding daily driver.

Looking back, it exceeded every expectation I had. It changed my opinion of hybrid cars completely, and that’s probably the biggest compliment I can give it.
