How many points will be deducted for driving at 60 in a 50 speed limit zone?

Speeding by 20% may result in different penalties depending on the location. Generally, the fine varies based on where the speeding occurred or the specific road speed limit. On highways, speeding typically incurs a fine and a deduction of 3 points. According to the "Speeding Penalty Regulations": On roads with a speed limit below 50 km/h, exceeding the speed limit by more than 10% but less than 20% will result in a fine; exceeding by more than 20% but less than 50% will also result in a fine; exceeding by more than 50% but less than 70% will incur a fine; and exceeding by more than 70% will result in a fine.

Is the Magotan equipped with a dry clutch or a wet clutch?

The Magotan is equipped with a wet dual-clutch system. A wet dual-clutch refers to the clutch plates being immersed in transmission fluid, whereas a dry dual-clutch has the clutch plates in direct contact with the engine flywheel. In terms of technical maturity and reliability, the wet dual-clutch system is more stable because the clutch plates operate in hydraulic oil, which provides a certain cooling effect. Below are the advantages of a wet dual-clutch transmission: 1. Fast shifting: The shifting time of a dual-clutch transmission is very short, even faster than a manual transmission, taking less than 0.2 seconds. 2. Fuel efficiency: The dual-clutch transmission eliminates torque interruption, meaning the engine's power is continuously utilized and always operates at its optimal level, leading to significant fuel savings. Compared to traditional planetary gear automatic transmissions, it is more conducive to improving fuel economy, with fuel consumption reduced by approximately 15%. 3. Comfort: Due to the fast shifting speed, each gear change in a DCT is very smooth, with the jerkiness minimized to a level that is hardly noticeable to the human body.
