Emissions, performance and MPG – DCT improves all three

Just as the continuously variable transmission (CVT) has struggled to see significant uptake primarily due to an unfamiliar shifting sensation, the dual-clutch transmission (DCT) has struggled to see significant penetration.

As the name would suggest, DCTs feature two separate clutches for odd and even gear sets. The idea is that one clutch prepares the next gear in advance, allowing for near-instant shifts – often in milliseconds for most modern systems. In practice, a DCT drives much like a traditional automatic gearbox by
