Engineering Explained

Engineering Explained is run by Jason Fenske, a mechanical engineering graduate with a passion for cars. He set up the channel to answer one question: how do cars work? New videos come out every week.

The videos explain the engineering inside cars, using whiteboards, physical models and data. Topics include engines, fuels, oils, tyres, hybrids and electric vehicles. Many videos test a claim in the news or an advert and check it against the physics. Recent series look at innovations that changed cars, and at clever solutions from carmakers such as Ferrari and Porsche. He is careful to show his working, so viewers can follow the reasoning rather than just the conclusion.

Some highlights include:

An explanation of a six-stroke engine design, and how the extra strokes change the way the engine works.

A look at steer-by-wire, where the steering wheel has no mechanical link to the wheels, and how one carmaker made it work.

An investigation into whether thin engine oils cause damage, using a major car recall to explain lubrication and wear.

The channel has over 4.2 million subscribers.

Cars bring together mechanical, electrical, materials and software engineering in one machine. This channel shows how an engineer reasons from first principles to answer real questions. It is a natural fit for anyone thinking about automotive or mechanical engineering, motorsport or the move to electric vehicles.
