Car Transmission Types Explained

A car's transmission controls how engine power is delivered to the wheels. Different transmission types offer different levels of control, comfort, efficiency and performance. The most common types include MT, AMT, AT, CVT, iVT and DCT.

Types of Car Transmissions

Transmission	Full Form & Simple Explanation
MT	Manual Transmission – The driver manually operates the clutch and selects gears using the gear lever.
AMT	Automated Manual Transmission – A manual gearbox in which the clutch and gear changes are operated automatically.
AT	Automatic Transmission – Changes gears automatically without requiring the driver to operate a clutch pedal.
CVT	Continuously Variable Transmission – Uses a continuously variable ratio instead of fixed traditional gears for smooth power delivery.
iVT	Intelligent Variable Transmission – A type of continuously variable transmission designed to provide smooth and efficient power delivery.
DCT	Dual-Clutch Transmission – Uses two clutches to manage different gears, allowing quick and smooth gear changes.

Which Transmission Is Best?

Transmission	Best Suited For
MT	Drivers who want maximum control, simplicity and an engaging driving experience.
AMT	City drivers looking for automatic convenience at a relatively affordable cost.
AT	Drivers who want smooth and comfortable automatic gear changes.
CVT	City driving, smooth acceleration and relaxed everyday driving.
iVT	Drivers looking for smooth, efficient automatic driving with continuously variable ratios.
DCT	Drivers who want quick gear changes and a sportier driving experience.

Manual vs Automatic Transmission

A manual transmission gives the driver direct control over gear selection and requires the use of a clutch pedal. An automatic transmission handles gear changes without requiring the driver to operate a clutch manually.

For heavy city traffic, an automatic transmission can be more convenient because there is less clutch and gear-shifting work. A manual gearbox, however, can appeal to drivers who prefer greater control over the car.

CVT vs DCT

CVT	DCT
Uses continuously variable ratios.	Uses two clutches and fixed gear ratios.
Prioritises smooth and seamless power delivery.	Designed for quick gear changes and stronger performance response.
Well suited to relaxed city and everyday driving.	Often preferred when sporty acceleration and fast shifts are important.

Which Transmission Should You Choose?

There is no single transmission that is best for every driver. A manual gearbox may be the better choice if you enjoy controlling the car yourself. For frequent city traffic, an automatic can make driving easier. CVTs and iVTs focus on smooth and efficient operation, while DCTs are generally aimed at drivers who value faster gear changes and a sportier response.

What is Turbo Petrol?

A turbo petrol engine uses a turbocharger to push more air into the engine. This allows the engine to produce more power and torque from a relatively small engine size. Turbo petrol cars generally offer stronger acceleration and better performance, especially during overtaking and highway driving.

What is e:HEV?

e:HEV is Honda's strong hybrid system that combines a petrol engine with an electric motor and battery. The system can drive the car using electric power, petrol-engine power, or a combination of both depending on driving conditions. The battery is recharged automatically through the hybrid system, including regenerative braking, so it does not normally need to be plugged in.

Turbo Petrol vs e:HEV

Type	Simple Explanation
Turbo Petrol	A petrol engine with a turbocharger that increases air intake to deliver stronger power and torque.
e:HEV	A hybrid system combining a petrol engine, electric motor and battery to improve efficiency and provide electric-assisted driving.

Car Transmission FAQs

What does MT mean in cars?

MT stands for Manual Transmission. The driver manually operates the clutch and selects gears.

What does AMT mean in cars?

AMT stands for Automated Manual Transmission. It uses a manual gearbox but automates clutch operation and gear changes.

What does AT mean in cars?

AT stands for Automatic Transmission. The gearbox changes gears automatically without requiring manual clutch operation.

What does CVT mean in cars?

CVT stands for Continuously Variable Transmission. It uses continuously variable ratios rather than conventional fixed gears.

What does iVT mean in cars?

iVT stands for Intelligent Variable Transmission. It is a continuously variable transmission designed for smooth and efficient power delivery.

What does DCT mean in cars?

DCT stands for Dual-Clutch Transmission. It uses two clutches to manage gear changes and can provide quick shifts.

Which transmission is best for city driving?

Automatic transmissions such as AT, CVT, iVT and AMT can be convenient for city driving because they reduce the need for manual clutch operation and frequent gear changes.

Which transmission is best for performance?

DCTs are generally well suited to performance-oriented driving because they can deliver quick gear changes, while a manual transmission can provide greater driver control.
