CVTs use a belt and pulley system instead of traditional gears. This allows for a seamless change in ratios, optimizing efficiency and smoothness. These transmissions are best for city commutes and for those who are keen on the fuel economy of their car. Additionally, some of the cars with CVT transmissions are the Honda City, Nissan Magnite, Renault Triber, and Toyota Glanza.

• proven technology

Cons

• Less fuel efficient as compared to CVTs and DCTs
• Slightly slower gearshifts

Intelligent Manual Transmission

Intelligent Manual Transmission is the youngest of all, features a manual gearbox and eliminates the need for the clutch pedal. Sensors and actuators engage the clutch electronically while shifting gears. These transmissions are ideal for someone who enjoys manual gearboxes but seek relief from the frequent clutch use in traffic. Some of the cars that offer iMT include Kia Sonet, Kia Seltos and Hyundai Venue.
