2025 Mercedes-Benz GLC 350e Plug-In Hybrid: Real-World Range & Performance Test

Electric Range and Driving Experience

• ⚡ Jen tests the 2025 Mercedes-Benz GLC 350e plug-in hybrid, starting with a full battery and an optimistic 60 miles of electric range.
• 🛣️ Driving normally, using AC, and without hypermiling, the vehicle achieved an impressive 73 miles of electric range, exceeding the estimated 54 miles by nearly 20 miles.
• 💡 The average efficiency was 3 miles per kilowatt-hour, which is considered fantastic.
• ☁️ The ride experience is described as comfortable, characteristic of Mercedes, with a less direct steering response and spongy brakes, contributing to a more relaxed driving nature.
• 💨 Acceleration from 0 to 60 mph is 6.2 seconds, with a slight delay as the car determines its power source.

Performance and Drivetrain

• 🐎 The GLC 350e combines a 2.0L turbocharged 4-cylinder engine (201 hp) with a 23.3 kWh battery, yielding a combined 313 horsepower and 406 lb-ft of torque.
• ⚙️ It features a 9G-Tronic transmission and comes standard with 4MATIC all-wheel drive.
• 🔋 The hybrid system's weight contributes to a bumpier ride, though self-leveling rear air suspension is included to mitigate this.
• 🔌 The vehicle supports DC fast charging up to 60 kW, capable of charging in approximately 30 minutes.

Interior and Technology

• 🛋️ The interior features a Sienna Brown and Black AMG interior with Anthracite wood and a leather-padded dashboard, offering a luxurious feel.
• 📱 The infotainment system uses Mercedes' third-gen MBUX software, supporting wireless Apple CarPlay and Android Auto.
• 🗣️ Voice commands are a key feature, allowing control of various functions like temperature and seat ventilation.
• 🎛️ Many controls are haptic buttons, including volume and seat adjustments, which some users may find less satisfying than physical buttons.
• 🔊 The optional Exclusive Trim includes a Burmester surround sound system and enhanced ambient lighting throughout the cabin.

Practicality and Packages

• 📦 The AMG Line package ($3,450) adds exterior styling elements like a special grille, aprons, side sills, and 20-in AMG wheels.
• 🏋️ The SUV has a towing capacity of up to 3,500 lb.
• 🧳 Cargo space is approximately 25 cubic feet behind the second row and 56 cubic feet with the seats folded.
• 🛠️ The HV battery is located under the cargo floor, leaving limited space for a tire mobility kit instead of a spare tire.
• 🚗 The Driver Assistance package ($1,950) includes adaptive cruise control, lane keep assist, and Pre-Safe safety features.

Off-Road and Slip Tests

• ⛰️ The vehicle was tested at a ranch using slip tests to evaluate its 4MATIC system's performance in low-traction scenarios.
• ⚠️ The GLC 350e successfully completed the front-wheel slip test and the diagonal test.
• ❌ However, it failed the three-wheel test when the right front wheel was on rollers, even after engaging off-road and sport modes.
• ✅ It did manage to get out of a similar extreme situation when the right rear wheel was on pavement, indicating better torque transfer to the rear axle in that specific scenario.

Pricing and Conclusion

• 💰 The base price for the GLC 350e starts at $59,900, while the tested model with numerous options is priced at $71,700.
• 🤔 While the comfortable interior, advanced tech, and exceptional electric range are positives, the failure in one of the extreme slip tests and the reliance on haptic buttons are noted drawbacks.
• 👍 For the base price, the GLC 350e is considered to have a lot going for it, but the higher-priced model may not be as compelling.
