Video: Alfaholics GTA-R vs MST Escort MKI vs Porsche 912c By Kamm

Noise. Glorious, unfiltered noise. Usually the preserve of sports – and supercars with upwards of eight cylinders. But what about the humblest engine of the lot? The lowly four pot. The beans-on-toast of the car world, right? But that's where you're wrong. Because in the next 20-minutes TG's Head of Car Testing Ollie Marriage will demonstrate how three restomods from Alfaholics, MST and Kamm can put a bigger smile on your face than something with twice the power, and twice the cylinder count.

From MST's throttle-boddied, 9,000rpm BDG engine to Alfaholics' bored and stroked 2.3-litre Twin-Spark and Kamm's Swiss-built air-cooled lightweight, turn it up, sit back - and bask in the sounds of the mighty four.
