Cars with Automated Manual Transmission
What is an Automated Manual Transmission (AMT)?
An automated manual transmission (AMT), also known as a semi-automatic transmission, is a type of transmission that combines the elements of a manual transmission and an automatic transmission. AMTs use an electronic control unit (ECU) to automate the clutch and gear changes, making them easier to drive than a traditional manual transmission. However, AMTs still require the driver to select the gears manually, unlike an automatic transmission.
How Does an AMT Work?
AMTs use a variety of sensors to determine the vehicle’s speed, engine speed, and gear position. The ECU then uses this information to control the clutch and gear changes. When the driver shifts gears, the ECU sends a signal to the clutch actuator, which disengages the clutch. The ECU then sends a signal to the gear selector, which moves the gear shift lever to the desired gear. Once the gear is engaged, the ECU sends a signal to the clutch actuator, which re-engages the clutch.
Advantages of AMTs
- Improved fuel economy: AMTs can improve fuel economy by up to 10% compared to traditional manual transmissions.
- Reduced emissions: AMTs can also reduce emissions by up to 10% compared to traditional manual transmissions.
- Easier to drive: AMTs are easier to drive than traditional manual transmissions, making them a good option for drivers who are new to manual transmissions or who have difficulty driving them.
- More affordable than automatic transmissions: AMTs are typically more affordable than automatic transmissions, making them a good option for budget-minded drivers.
Disadvantages of AMTs
- Less engaging to drive: AMTs can be less engaging to drive than traditional manual transmissions, as the driver does not have to control the clutch or gear changes.
- Slower acceleration: AMTs can be slower to accelerate than traditional manual transmissions, as the ECU takes time to process the driver’s commands.
- Can be jerky: AMTs can sometimes be jerky when shifting gears, especially at low speeds.
Which Cars Offer AMTs?
Several car manufacturers offer AMTs in their vehicles. Some of the most popular cars with AMTs include the:
- Chevrolet Spark
- Fiat 500
- Ford Fiesta
- Hyundai Accent
- Kia Rio
- Mazda2
- Mitsubishi Mirage
- Nissan Versa
- Suzuki Swift
- Toyota Yaris
- Volkswagen Golf
Conclusion
Automated manual transmissions are a good option for drivers who want the fuel economy and reduced emissions of a manual transmission without the hassle of having to control the clutch and gear changes. However, AMTs are not as engaging to drive as traditional manual transmissions and can be slower to accelerate and jerkier when shifting gears. If you are considering buying a car with an AMT, be sure to test drive it first to see if it is the right choice for you.
