3 Answers
Mercedes-Benz GLS is equipped with two engines, namely a 3.0T twin-turbocharged engine and a 4.0T twin-turbocharged engine, with model numbers 256930 and 278912 respectively. The 3.0T engine has a maximum power of 270 kilowatts and a maximum torque of 500 Newton-meters, while the 4.0T engine has a maximum power of 310 kilowatts and a maximum torque of 600 Newton-meters. The transmission system paired with the engines is a 9-speed automatic manual transmission. The Mercedes-Benz GLS is a large SUV under the Mercedes-Benz brand, with a body length, width, and height of 5130mm, 1982mm, and 1849mm respectively, and a wheelbase of 3075mm.
When researching luxury SUVs before, I paid special attention to the powertrain of the Mercedes-Benz GLS. There are significant differences in engine configurations across different model years. The current main domestic model, the GLS 450, uses a 3.0-liter inline-six turbocharged engine codenamed M256, paired with 48V mild hybrid technology for exceptional fuel efficiency. The older GLS 400 model featured a 3.0T V6 engine from the M276 series. For those seeking ultimate power, the GLS 580's 4.0T V8 engine is truly impressive, delivering over 500 horsepower on demand with twin-turbo boost. When choosing a vehicle, remember to check the vehicle identification plate or have the salesperson verify the specific model, as parallel import versions might even come with diesel engines.
Last month, I just helped a client inspect a used GLS, with a focus on checking the engine condition. The currently available GLS 450 is equipped with the M256 engine, and the standout feature of this six-cylinder engine is its fast electronic turbo response, paired with the EQ Boost mild hybrid system for exceptionally quiet start-stop operation. In contrast, the discontinued older model GLS 400 used the M276 engine, where more attention should be paid to the aging of the engine mounts. The top-of-the-line GLS 580 overseas comes with the M176 4.0-liter V8, but it's relatively rare in the domestic market. During the inspection, it's essential to open the engine hood to verify the cylinder block number, as there are subtle differences in water pump designs across different batches.
