Whether you're navigating city streets or embarking on a long road trip, this car promises to deliver a comfortable and enjoyable driving experience.

Understanding Key Terms

Before diving into the specifics, let's clarify some essential terms. A 'mild hybrid' refers to a vehicle that uses a small electric motor to assist the internal combustion engine, improving fuel efficiency and reducing emissions. The '4MATIC' is Mercedes-Benz's all-wheel-drive system, providing better traction and stability. The '9G-TRONIC' is a nine-speed automatic transmission that ensures smooth and efficient gear changes.

Main Features of the 2023 Mercedes-Benz GLC Coupe

The GLC 300 is powered by a 2.0-liter inline-four engine, producing 258 horsepower and 400 Nm of torque. This engine is paired with a 48-volt mild hybrid system, adding an extra 23 horsepower and 200 Nm of torque. This setup allows the GLC 300 to accelerate from 0 to 100 km/h in just 6.3 seconds, with a top speed of 246 km/h (152.86 mph).

Fuel efficiency is a highlight, with a combined consumption of 7.3-8.2 liters per 100 km (32.22 - 28.68 US mpg). The CO2 emissions range from 165 to 185 g/km, adhering to the Euro 6d-ISC-FCM emission standard.

In terms of design, the GLC Coupe features a coupe-like silhouette, offering a sporty yet elegant appearance. It seats five comfortably, with a spacious trunk that ranges from 545 liters to 1490 liters when the rear seats are folded down.
