What does 5-speed mechanical automatic mean?
3 Answers
5-speed mechanical automatic refers to a 5-gear AMT automatic transmission, which is a type of transmission device that can automatically shift gears based on the vehicle's speed and engine RPM, as opposed to a manual transmission. The functions of an AMT automatic transmission are: 1. To change the transmission ratio and expand the range of torque and speed variations of the driving wheels, allowing the engine to operate under favorable conditions; 2. To enable the vehicle to reverse while maintaining the engine's rotational direction; 3. To interrupt power transmission by using neutral gear, allowing the engine to start, idle, and facilitating gear shifting or power output.
I've been pondering over the term '5-speed automated manual' for quite some time. As a seasoned driver of economy cars, it's essentially a manual transmission with an automated mechanism that handles clutch engagement and gear shifts for you, offering five gears in total. It's less labor-intensive than a pure manual (no clutch pedal stomping), yet not as smooth as a full automatic—feels somewhat half-baked. I drove a Peugeot 208 equipped with this transmission; it's indeed hassle-free in city traffic jams, but uphill, the power delivery lags noticeably, like it's always a beat behind. Fuel consumption is slightly higher than a manual, but maintenance is cheaper—replacing small parts won't break the bank, thanks to its simple and rugged design. For budget-conscious folks, it strikes a balance between cost and convenience. Just don't expect silky-smooth performance during spirited driving—jerks are common, but you'll adapt. For daily commutes, it's absolutely sufficient.
As a family car user, I'm quite familiar with 5-speed automated manual transmissions in my driving experience. It means the gearbox has five forward gears, essentially a manual transmission system with computer-controlled shifting. My Chevrolet Aveo is equipped with this, making school runs with kids effortless without constantly fiddling with the gear lever. The advantages are obvious: affordable pricing, significantly cheaper than traditional automatics when new; decent fuel efficiency, quite economical on highways. The downside is occasional jerks during slow starts or sudden acceleration, causing slight jolts passengers might feel. Maintenance is straightforward, just regular gear oil checks. Long-term, it suits budget-conscious families offering automated convenience, but if you prioritize ultimate smoothness, CVT or dual-clutch might be better options. Overall, it's very practical for daily commutes.
