GEARING UP FOR THE FUTURE
Most cars still use manual or automatic gearboxes, but some new vehicles have modern continuously variable transmission (CVT) or dual-clutch systems. CVT is a type of automatic gearbox, but differs from conventional hardware in one key way. Instead of using normal gears, where drivers can feel the transitions, CVT gearboxes have a cone-shaped design and a system of pulleys to create a smooth transition up and down the car’s power range. It’s an efficient system that’s often used in hybrids. Dual-clutch systems are often found in semi-automatic cars – the inclusion of two clutches means cars can preselect gears, which means you get incredibly quick gearshifts. You’ll also find this system on high-performance cars and vehicles with gear-shifting paddles on the wheel. Manual gearboxes aren’t immune from innovation either. Volkswagen has produced a new manual gearbox called the MQ281 that massively improves efficiency and reduces emissions.
