Recently, I spent the morning at Ferrari’s Modena plant partly because the company wants to make a point of its green credentials.

Ferrari has spent the last few years completely re-building Modena, not only installing smart new production lines but also new buildings that consume less energy and 4000sq meters of solar panels.

However, the Italians have gone one step further and built their own mini on-site power station, which provides not only electricity but also cooled water and super-heated water.

Hard-hated and ear-defended, we were allowed into the bowls of the Modena power station to see an extraordinary sight.

At the heart of the operation are two more-than-room-sized V20 (yes, that’s 20-cylinder) engines. Each motor measures in at 769-litres and churns out the equivalent of 23,000bhp.
