Here, starting with the engine, both have a similar type of engine but one is diesel powered and the other one is petrol. Normally, diesel-powered engines are more powerful and provide more mileage. However, the pollution, or we can say the carbon emission rate of the diesel engine is high.

According to the technical feature description for GL350 and GL450, both of them have V6 engines with 26.4 gallons of the fuel tank. However, the GL350 has less horsepower but more torque. Also, it will cover more mileage with the same tank than the GL450. Even if the carbon emission is slightly higher than the other one, this one will go far more mileage than the GL450 vehicle.

The reason for the differences in mileage between this two can be the carbon emission or the dimension. Since they do not have that much a difference in carbon emission to support that mileage variation, we can look into the dimension differences.

Clearly, both of the trim do not share so many differences in dimension too. In fact, we can say that they have the same exterior dimension with 7 seating capacities. So, there is no strong point to justify the huge difference in mileage. So, one can raise a question then why the GL450 is more expensive than the other one.

Well rather than the technical and dimensional features, a vehicle has so much more to offer. The technology, comfort, and modern security system added to the car will add to the price. Here the GL450 must have more valuable features in the mentioned criteria which increased the price range.

Overall, the GL450 will have a more spacious third row with more cargo capacity. Also, the technology in this time will be somewhat better than in the other one. besides, the engine and the power of this one will be better. In the case of the value of money in an overview, people may have selected the GL350 if the other not-so-mandatory criteria do not apply to them.


Looking for the best among the best is a tough job. However, one can crack the mystery by dividing the features and comparing them with one another. Also, matching the benefits with their desired criteria will help find the best option. Here, both of the cars belong to the same brand and same class. However, they have a lot of differences in price and performance. Hopefully, the discussion on GL450 Vs GL350 helped me choose the right one.
