The differences between the GLC260 and GLC300 are as follows: 1. Different maximum horsepower: the GLC260 has a maximum horsepower of 197 hp; the GLC300 has a maximum horsepower of 258 hp. 2. Different maximum torque: the GLC260 has a maximum torque of 320 Nm; the GLC300 has a maximum torque of 370 Nm. 3. Different 0-100 km/h acceleration times: the GLC260 accelerates from 0-100 km/h in 8.4 seconds; the GLC300 does it in 6.9 seconds. 4. Different maximum power: the GLC260 has a maximum power of 320 kW; the GLC300 has a maximum power of 190 kW.

I'm quite familiar with the differences in the Mercedes-Benz GLC series. The core distinction between the GLC260 and GLC300 lies in their engine performance. The 260 version is equipped with a 2.0-liter turbocharged engine, delivering relatively lower power output at around 200 horsepower, making it ideal for daily commuting with smooth acceleration though not particularly thrilling. The 300 version also features a 2.0-liter engine but boosts horsepower to approximately 250, offering stronger burst power and noticeable back-push sensation during startup, catering to those who seek driving excitement. In terms of fuel consumption, the 260 averages about 9L/100km in urban conditions, being more economical, while the 300 is slightly higher at 10L, but the performance justifies the cost. The chassis and interior are virtually identical, both featuring the MBUX system with no difference in space comfort. My recommendation is: if you mostly drive in the city, the 260 saves fuel and money; if you prefer quick starts or frequent long-distance highway driving, the 300 delivers more power, where the extra tens of thousands spent translate into a tangible upgrade in driving experience. Of course, the overall quality is unquestionable – Mercedes-Benz builds reliable cars.

As a family user, I value cost-effectiveness and practicality. The differences between the GLC 260 and 300 are not significant, but each has its own strengths. The 260 is considerably cheaper, with a lower out-the-door price by tens of thousands, and it has slightly better fuel efficiency, averaging around 8.5 liters in the city, making it more economical to maintain—ideal for budget-conscious families for daily commuting. The 300 is more expensive but offers higher horsepower, providing more stability when overtaking on highways and slightly better safety. However, its fuel consumption is higher at 9.5 liters, making it less cost-effective for long-term driving due to higher fuel expenses. Both models feature comfortable and quiet interiors, spacious cabins, and foldable rear seats for large luggage, ensuring ample space for kids. In my opinion, if you primarily drive in the city for school runs and shopping, the 260 is sufficient and more economical. If you frequently drive on highways or prioritize power, the 300 offers more peace of mind. Overall, both are reliable choices—just don’t overlook regular maintenance, as Mercedes-Benz vehicles are built to last.

From a mechanical perspective, the difference between the GLC260 and 300 lies in engine tuning. The 260 is equipped with a lower-power turbocharger, featuring a slightly smaller compression ratio and delivering around 200 horsepower, resulting in slower acceleration. The 300 boosts power output to over 250 horsepower by increasing boost pressure, with optimized pistons and fuel injection systems for quicker response, shaving 1-2 seconds off the 0-100 km/h acceleration time. Both share identical chassis suspension and transmission components, with similar maintenance costs, though the 300 consumes slightly more fuel. As someone who frequently services Mercedes models, I've observed the 260 has lower failure rates, making it ideal for daily commuting, while the 300's engine bears higher loads and requires more frequent oil changes and maintenance. Don't underestimate these differences—choosing the right model can save both hassle and money.
