New Car Pricing
Let’s face it—price is a big deal. When choosing between the Mercedes CLA and the Tesla Model 3, your wallet will definitely feel the difference. The new CLA, especially the 350 4MATIC or AMG variant, tends to start around $40,000–$50,000 depending on trim and packages. Meanwhile, a Tesla Model 3, including the Long Range and Performance trims, can vary from $38,000 to upwards of $55,000. Both cars have options that can stretch your budget fast.
Used Car Market Value
In the used car market, things shift slightly. The Mercedes-Benz CLA tends to depreciate faster, which can be great for buyers looking for value. The Tesla Model 3, on the other hand, holds its value surprisingly well. Thanks to over-the-air updates and the whole Elon Musk brand aura, resale is strong. That said, used prices are still competitive for both if you dig into the car details. Don’t forget that Tesla’s regular software improvements can sometimes boost used values, while the CLA shines with certified pre-owned deals that include warranty extensions and maintenance perks.
Performance And Efficiency
Mercedes Cla 250 (Gas)
- 2.0L turbocharged engine with 221 hp
- 0–100 km/h in ~6.3 seconds
- FWD (AWD optional with 4MATIC)
The CLA delivers a smooth, quiet ride with good power. The AMG trims offer even more excitement for performance lovers.
Tesla Model 3 (Rwd / Long Range / Performance)
- Instant electric torque
- 0–100 km/h as fast as 3.1 seconds (Performance model)
- Dual-motor AWD available
The Model 3 is the faster and more responsive car, thanks to its electric powertrain. Great for drivers who prioritize acceleration and cutting-edge feel.
Engine Vs Electric Motor
Choosing between a gas engine and an electric motor is like picking between espresso and matcha—they’re both energizing but deliver differently. The Mercedes CLA runs on turbocharged petrol engines, especially in 45 S AMG trim, which means traditional revs and sound. The Tesla Model 3, powered by a whisper-quiet electric motor, delivers instant torque and a different kind of thrill. The performance in the Model 3 is linear and lightning-fast, while the CLA offers a more traditional crescendo of engine notes and turbo pull.
Fuel Economy And Range
CLA 250 (Gas)
- Fuel economy: ~28–30 mpg combined (approx. 8–9 L/100km)
- No charging required—but you’ll need gas, of course.
Tesla Model 3
- EV range: 438–576 km (depending on trim)
- Zero gas, charges at home or Tesla Supercharger network
Tesla wins big here. If you’re ready to go electric, the Model 3 is more efficient and cheaper to run long-term.
The Tesla Model 3 Long Range dominates here, offering over 350 miles on a charge. And with the Tesla Supercharger network expanding across cities like Los Angeles, range anxiety is fading fast. The CLA, depending on trim, delivers 25–35 MPG but obviously requires gas stops. The Tesla can also charge at home, saving time and money over the long run, while CLA drivers may appreciate traditional refueling convenience during road trips where charging infrastructure isn’t yet complete.
Design And Luxury Features
Mercedes CLA
- Sporty “four-door coupe” silhouette
- Sleek LED lighting, diamond grille, and premium paint options
- Classy, luxurious German design inside and out
The CLA is for those who want a bold, elegant exterior paired with a refined interior—complete with ambient lighting and upscale materials.
Tesla Model 3
- Minimalist and futuristic design
- Clean lines, flush door handles, and a very aerodynamic look
- Inside: One large center screen and nearly zero buttons
Tesla’s design is clean and modern—but might feel a bit too minimal for drivers who want traditional luxury touches.
Interior Aesthetics
If you love minimalist design, the Model 3 interior is as clean as it gets—just one screen, very few buttons. It’s a vibe. On the other hand, the Mercedes CLA’s cabin feels rich. Think Mercedes logo on the steering wheel, ambient lighting, and luxe materials. The Concept CLA Class previews even more luxury touches like wraparound LED strips and floating digital clusters. Tesla’s interior may feel stark to some, while the CLA’s cockpit-like environment oozes premium charm.
Exterior Style
The CLA wears its German carmaker heritage proudly. Sleek lines, coupe-like curves, and AMG touches make it stand out. Tesla’s exterior is cleaner and more tech-forward—less showy, more functional. Whether you prefer the muscular CLA Shooting Brake look or the futuristic Tesla Model 3 Performance stance depends on your taste. Both turn heads, but one leans classic sporty, the other futuristic minimalist.
Dimensions And Space
Interior Dimensions
Surprisingly, the Tesla Model 3 feels roomier inside. Flat floors and minimalist design help open up cabin space. But don’t count the CLA Sedan out—it still offers decent second row comfort, though it leans sporty rather than spacious. Tesla’s under-floor battery also creates a low center of gravity, helping stability and freeing up storage.
Exterior Dimensions
The Model 3 is slightly longer and wider than the CLA, giving it a more planted road presence. The Mercedes-Benz CLA is compact and sleek, better suited for tight city parking. Both fit nicely in the compact sedan category but serve different needs. The Model 3’s trunk space and cargo space up front (frunk) offer added practicality.
Safety And Reliability
Safety Ratings And Features
Both score high on safety. The Tesla Model 3 gets top marks for crash tests and comes loaded with features like automatic emergency braking. The CLA brings Active Brake Assist, lane-keeping tech, and a suite of safety features as standard. Whether it’s radar-guided or camera-based, both offer peace of mind. Tesla’s reliance on vision-only tech may concern some, while Mercedes’ mixed sensor suite feels more traditional and battle-tested.
Long-Term Reliability
Electric cars like the Model 3 have fewer moving parts, which often means fewer issues. Still, software glitches can happen. The Mercedes-Benz Group has years of experience in mechanical engineering, and the CLA’s reliability is well-documented. While Tesla may shine in drivetrain simplicity, Mercedes shines in quality control and service consistency.
Drivetrain And Engine Specifications
Mercedes-Benz Drivetrain Options
The CLA offers front-wheel drive and 4MATIC all-wheel drive options. Turbocharged four-cylinder engines are standard, with powerful upgrades in the AMG variant. If you want the full growl-and-go experience, the CLA’s your pick. Plus, future Mercedes EV options will use the upcoming Mercedes Modular Architecture (MMA platform).
Tesla Model 3 Drivetrain Options
The Model 3 comes in rear-wheel drive and dual-motor AWD setups. Torque delivery is instant, and there’s no gear-shift delay. Whether you choose standard or Performance, acceleration is blistering—0–60 mph in under 4 seconds in some cases. The electric model also adjusts power distribution on the fly for better traction.
Technology And Infotainment
Mercedes CLA
- MBUX infotainment system with dual screens
- “Hey Mercedes” voice assistant
- Apple CarPlay/Android Auto, advanced safety features
Mercedes wins on interior ambiance—the screens are sharp, and the system feels high-end and customizable.
Tesla Model 3
- Massive 15″ central touchscreen controls almost everything
- Regular software updates over-the-air
- Autopilot and optional Full Self-Driving
Tesla feels more like a tech product than a car—for better or worse. If you like touchscreens and minimalism, you’ll love it.
Infotainment Systems
Tesla keeps it sleek with a single 15-inch touchscreen that controls almost everything. It’s clean, but takes getting used to. The Mercedes CLA, on the other hand, blends screens with physical buttons. The MBUX system with voice command and haptic feedback is a tech-lover’s dream. Plus, it supports EQ technology that syncs with vehicle systems for better energy flow and UI personalization.
Advanced Driver Assistance
The Model 3 shines here with Autopilot and available Full Self-Driving (FSD) capabilities. But don’t discount the CLA—its Active Brake Assist, adaptive cruise control, and lane keep assist make highway drives smoother. Tesla may promise more automation, but Mercedes delivers proven, real-world-friendly driver support.
Customization Options
Exterior Color Options
Tesla offers a simple palette—black, white, silver, blue, red. The CLA gives you more freedom with bold shades, matte finishes, and AMG-specific tones. If personal flair matters, Mercedes wins this round. Plus, custom trim and wheel packages let buyers make the CLA truly theirs.
Interior Material Choices
The Model 3 has a modern vibe, with vegan leather and minimalist textures. The CLA brings you luxury-grade materials, customizable stitching, and warm finishes that reflect its luxury DNA. Mercedes lets you build the feel you want—from business class sleek to lounge-like indulgence.
Market Perception And Brand Appeal
Mercedes-Benz Brand Image
There’s just something iconic about the Mercedes-Benz badge. It screams heritage, performance, and a certain level of class. Whether you grew up watching your favorite celeb step out of a Concept CLA Class or admired your neighbor’s Mercedes EV, it sticks with you. That three-pointed star still means something globally.
Tesla’s Market Influence
But Tesla’s no slouch. It’s the brand that disrupted everything. From the Vision EQXX to the Tesla Roadster, the hype is real. And with Elon Musk constantly pushing boundaries, it’s not just a car—it’s a tech lifestyle. The Tesla Model 3 rival argument now includes legacy makers like BMW and Mercedes scrambling to catch up.
Final Thoughts
Choosing between the Mercedes CLA or Tesla Model 3 isn’t easy. If you want traditional luxury, roaring engines, and timeless design, the Mercedes-Benz CLA delivers. If you’re all about tech, instant torque, and driving into the electric future, the Tesla Model 3 is your match.
Both cars have strong points—Mercedes nails comfort and familiarity, while Tesla rewrites expectations. You’ll have to weigh brand identity, driving feel, tech, and even lifestyle alignment. For some, the Kia EV6 or BMW i4 may even sneak into the decision.
Whichever you choose, you’re not just buying a car—you’re stepping into a story. One rooted in either engineering heritage or electric innovation. The good news? You can’t really go wrong.
