In truth, these days itвЂ™s probably easier to say which cars arenвЂ™t turbocharged. Nissan badges its turbo petrols DIG-T, expect to find these in the Juke and Qashqai crossovers.

RenaultвЂ™s TCe family of turbo petrol engines, found in the Clio and Captur, is another - you can find these TCe engines in some Dacias too. One of the best known, small petrol turbos is FordвЂ™s family of EcoBoost engines, found on models including the Fiesta and Focus. Other companies use CRDi, BlueHDi and a simple 'd' suffix after the model name, as with Mercedes and BMW. Audi, Volkswagen, Seat and Skoda turbodiesels are often badged TDI, short for Turbocharged Direct Injection. Turbocharged engines go under a variety of names. Even big SUVs often come with small turbo petrol engines these days, as the engines are now efficient and powerful enough to propel larger vehicles.

Meanwhile, petrol turbocharging is now making a big comeback. Today, nearly all diesel engines are turbocharged. However, as diesel engines caught on, it began to be used in these, too. Which engines use a turbo?ДЇor many years, turbocharging was mainly used in petrol engines. Essentially, a turbo turns waste energy into power. ThatвЂ™s pretty clever, but cleverer still is the fact that the impeller is powered not by the engine, but by the exhaust gas produced when the fuel and air detonate. The vast quantity of high-speed air that it produces exits the impeller and shoots down the other end of the turbo into the engine, where it mixes with fuel to create a bigger bang and more power. Air is drawn in from the outside at one end, and as it travels along, is compressed by an impeller spinning at very high speeds. Not surprisingly, given what it does, it looks a bit like a hairdryer, and it sits under the bonnet.
