The Engineering of a Sequential Gearbox

It is the kind of technology most drivers benefit from every day without ever thinking about it. Pop the bonnet on how it works, though, and there is some genuinely elegant engineering to appreciate.

How it works

The principle relies on reacting faster and more accurately than a human ever could. Sensors gather information, a controller makes a decision in milliseconds, and the hardware responds before the driver is even aware of the situation.

Why it matters

The payoff is a car that is safer, faster or more efficient — often all three at once. That is why the technology spread so quickly from exotic machinery to mainstream models.

Great engineering is invisible until you understand it — then it is everywhere.

The bottom line

Understanding the why behind the feature turns a black box into something you can appreciate — and, occasionally, exploit to drive better.
