Some of the most common engine types are the inline-four, V6 and V8s. Exotic cars have the occasional V10 or V12 and some economy cars have tiny three-cylinder engines, but that is basically the full-range of engine types (we didn't forget the rare rotary). Five-cylinder is a much less common engine type that only a few manufacturers have ever embraced. Audi really made the five-cylinder catch on with the mighty Sport Quattro, and the VW Group has been doing good things with these engines recently. Here are our five favorite five cylinders of all time.

Audi has most recently reminded us of why we love the five-cylinder engine so much. The TT-RS and RS3 both use a 2.5-liter turbocharged five-cylinder engine that sounds like a supercar. This engine sounds like a mini R8, and is definitely the best sounding in its segment.

The new Ford Focus RS has been hyped up because it is the first RS model to finally be sold in the US. The current car has a 2.3-liter turbo four-cylinder, but the old car was powered by a 2.5-liter five-cylinder turbo engine that was engineered by Volvo (which Ford owned at the time).

Alfa Romeo has finally returned to the US, but the 159 is an Alfa that the US never received. The car was built on a FWD platform and came with a variety of engines. One of the most unique engines was the 2.4 JTD diesel engine that produced 207 hp and 295 lb-ft of torque. This is one of the best sounding diesel engines of all time.

The Audi RS2 wagon is one of the cars that we are most upset about the US never receiving. The car was codeveloped with Porsche and was powered by a 2.2-liter inline-five with 311 hp. When it came out, it was one of the quickest cars in the world to 30 mph thanks to its impressive AWD system.

Before Fiat returned to the US, it built a car called the Coupe Turbo. It was a simple name that described exactly what the car was. The Fiat Coupe Turbo was powered by either a 2.0-liter four or five cylinder engine. The five-cylinder produced 217 hp and 229 lb-ft of torque and was one of the fastest FWD cars at the time.
