What does the three differential locks on the Mercedes-Benz G-Class mean?
2 Answers
Mercedes-Benz G-Class's three differential locks refer to the central differential lock, rear axle differential lock, and front axle differential lock. The central differential lock enables a 50-50 power distribution between the front and rear axles, meaning it ensures equal power allocation to both axles. The rear axle differential lock is particularly crucial, as it rigidly connects the two rear wheels for synchronized power delivery. The front axle differential lock similarly connects the two front wheels rigidly, ensuring equal power output. Taking the Mercedes-Benz A-Class as an example: the A-Class measures 4622mm in length, 1796mm in width, and 1454mm in height, with a wheelbase of 2789mm. It is a 4-door, 5-seater sedan equipped with a 7-speed dual-clutch transmission.
The often-mentioned 'three locks' on the Mercedes-Benz G-Class actually refer to the front, center, and rear differential locks. When off-roading in this vehicle, encountering wheel spin is the most annoying, but engaging the differential locks ensures power is evenly distributed to all wheels. The sequence of locking is also particular: first press the center differential lock button to fix power distribution between the front and rear axles, then lock the rear and front axles in sequence. With all three locks engaged, even if one wheel is lifted off the ground, the vehicle can climb out relying on the traction of the remaining tires. However, never randomly engage the differential locks on regular roads, as this can cause clunking noises and damage components during turns. This mechanical locking system is considered top-tier in the hardcore off-road world, making the G-Class a formidable tool for conquering mountains and rough terrain.
