6 Differences between the Mercedes C300 and C43 AMG

Ready to put the Mercedes C300 and C43 AMG head-to-head?

Here are all the differences between them!

1. Engine

First up, the main difference; the Mercedes C300 and the C43 AMG have different engines.

Here is an overview of their engines and engine performance:

MercedesEnginePower (hp)Torque (lb-ft)0 to 62 mph
C3002.0-liter four-cylinder 2552735.6 seconds
C43 AMG3.0-liter V63853844.6 seconds

First up, the Mercedes-Benz C300 comes with a 2.0-liter four-cylinder engine with 255 horsepower. It’s not too heavy or light but just right for daily drives, weekend trips, and those occasional overtakes on the highway.

Now, enter the C43 AMG. This one’s got some extra muscle under the hood.

With its 3.0-liter V6 engine, it has a whopping 385 horsepower, which means quicker acceleration, a deeper engine growl, and an overall sportier vibe.

To sum it up, if you’re looking for more raw power and acceleration, the C43 AMG’s engine will give it to you. But if you’re content with a dependable engine that’ll more than meet daily driving needs, the C300 is no slouch.

2. Fuel economy

Picture this: you’re on a long drive, perhaps cruising down the countryside or going through the city’s bustling streets.

One thing you don’t want to worry about? Having to stop too frequently for gas.

That’s where fuel economy steps in.

The Mercedes C300, with its 2.0-liter four-cylinder engine, manages a pretty decent 24 MPG combined. Not too shabby, right?

On the flip side, the C43 AMG, with all its added power and performance, sips a bit more fuel. It scores 22 MPG combined.

Now, that’s only a slight dip from the C300, but it’s the trade-off you make for that extra performance!

In the grand scheme of things, both these cars do a pretty decent job of offering power while being relatively kind to the environment (and your fuel budget).

3. Rear-wheel drive vs. all-wheel drive

Let’s talk about how these cars deliver power to the ground.

The Mercedes C300 offers you choices. You can go for the rear-wheel drive (RWD) or opt for the all-wheel drive (AWD), known as 4MATIC.

While the C300 is available in both RWD and AWD configurations, the C43 AMG always comes as an AWD.

With RWD, the car pushes itself from the rear, which many drivers love for its sporty and traditional driving feel. On the other hand, the 4MATIC option means power goes to all four wheels, offering better grip, especially on slippery roads.

4. Brakes and suspension

Next on the list? Brakes and suspension.

Starting with the C300: its brakes and suspension are set up for daily comfort. The suspension smoothly soaks up bumps and irregularities, making city commutes and long highway cruises enjoyable.

The C43 AMG comes with sport-tuned suspension. It’s stiffer, allowing you to feel the road and tackle corners with added precision.

And the brakes? They’re bigger and offer more stopping power!

5. Styling

Mercedes-Benz is known for its iconic design language: sleek lines and that instantly recognizable emblem.

But when we dive into the specifics of the C300 and C43 AMG, some distinct style choices set them apart.

The C300 is all about sophisticated elegance.

Its design feels like a classic suit – timeless, refined, and suitable for any occasion. Clean lines flow from front to back, and its features, while understated, speak of luxury. It’s the kind of car that gets admiring glances without screaming for attention.

Now, the C43 AMG is the C300’s extroverted sibling.

With AMG styling, it brings a more aggressive, athletic look to the table.

Specific front and rear styling tweaks hint at its performance. And those four exhaust tips? They’re not just there for the aesthetics; they’re a promise of the roaring sound that lies within.

Add to that a decklid spoiler and those wind-tunnel-tested lightweight wheels, and you’ve got a car that looks fast even when it’s standing still!

6. Retail price

Now, let’s tackle the question that’s often on many minds: “What’s the damage to my wallet?”

Well, the Mercedes C43 AMG has an MSRP that’s about $10,000 to $14,000 more compared to the C300 4MATIC.

But remember, with that added cost; you’re getting improved performance, sportier aesthetics, and exclusive AMG-specific features!

What is the best choice? (Mercedes C300 vs. C43 AMG)

Decisions, decisions.

We’ve broken down the differences, but which one is best? Which one should find a spot in your garage?

Let’s break it down together: the Mercedes C300 versus the C43 AMG. Here are the things you should consider:

  • Your Driving Needs: If you’re someone who loves a good-sounding engine and the thrill of acceleration, the C43 AMG might be your ideal match. On the other hand, if you’re more into smooth, daily commuting, the C300 will serve you well.
  • Budget Considerations: Let’s not skirt around it – budget matters. If you’re ready to shell out those extra bucks for performance, aesthetics, and AMG’s brand equity, then by all means, get the C43 AMG. However, as a more budget-friendly package, the C300 is an absolute gem.
  • Fuel Economy: The difference isn’t vast, but every mile per gallon counts. If optimum fuel efficiency is your thing, then the C300 has a slight edge.
  • Styling Preferences: This is subjective. Some love the understated elegance of the C300, while others lean towards the flashy sportiness of the C43 AMG. What makes you turn your head? That’s your answer.
  • Drive Configuration: If you live in a region where roads are often slick, or you just love the assurance of all-wheel drive, the guaranteed 4MATIC of the C43 AMG (or the optional one in the C300) is for you. For those who enjoy a classic rear-wheel driving feel, the C300’s RWD option might be the way to go.

In the end, the C300 offers luxury at a more accessible price point, while the C43 AMG brings sporty aggression and superior power to the table.

And hey, there’s no wrong choice here. After all, you’re still driving home in a Mercedes at the end of the day.

One extra note is that if you ever want to get closer to the power of the C43 AMG in your C300, you can always consider getting a RaceChip.
