Does the Golf use a dry or wet clutch?
2 Answers
The Golf uses a dry dual-clutch transmission, but its working principle is essentially the same as that of a wet dual-clutch transmission. Both utilize two clutches for alternating operation, with the difference lying in the medium connecting the driving and driven plates. The wet dual-clutch transmission primarily relies on oil, while the dry dual-clutch transmission mainly depends on air. The dual-clutch transmission (DCT) differs from conventional automatic transmissions. It is based on a manual transmission but is not an automatic transmission. In addition to offering the flexibility of a manual transmission and the comfort of an automatic transmission, it also provides uninterrupted power output. Traditional manual transmissions use a single clutch, requiring the driver to press the clutch pedal during gear shifts to engage different gears. This results in a power interruption during gear changes, causing intermittent output performance. The dry dual-clutch was developed based on the technology of the 6-speed DQ250 wet dual-clutch, simplifying the related hydraulic system.
I recently bought a new car, a manual transmission Golf with a dry clutch, meaning it operates through direct friction without being immersed in oil. Driving in congested city traffic, the clutch feels very responsive—just a press and I can shift gears, making it light to operate and fuel-efficient. However, this dry design tends to overheat during prolonged uphill drives or heavy traffic, leading to faster wear of the clutch plates. I've experienced slipping a few times, so regular checks of the clutch disc and pressure plate are necessary. Maintenance is simple and cheap, with part replacements costing just a few hundred yuan, but it's not as durable as a wet clutch. I recommend getting it inspected every few years to avoid breakdowns. Overall, manual transmission enthusiasts will appreciate the direct control feel of the dry clutch, but it can be a bit tiring for frequent city driving.
