Which UK cars have 4-cylinder engines?

Most modern petrol and diesel cars in the UK with engine sizes under 2.5 litres typically use 4-cylinder engines. Popular UK models with 4-cylinder engines include the Ford Focus 1.0 EcoBoost, Vauxhall Corsa 1.2 Turbo, Volkswagen Golf 1.5 TSI, and BMW 320i.

4-cylinder engines (also called 4-pot engines in the UK) are common in small to medium-sized family cars and are known for their good balance of performance and fuel efficiency. The total displacement (sum of all cylinders' capacity) is measured in litres.

These engines work by converting fuel's chemical energy into mechanical energy through controlled explosions in the cylinders. Key components include the cylinder block, crankshaft, cylinder head and head gasket.

Many popular UK models offer 4-cylinder options across different fuel types:

• Petrol: Mini Cooper 2.0, Nissan Qashqai 1.3 DIG-T
• Diesel: Skoda Octavia 2.0 TDI, Mercedes A200d
• Hybrid: Toyota Corolla 1.8 Hybrid, Ford Puma 1.0 EcoBoost Hybrid

4-cylinder engines remain popular in the UK market due to their compact size, lower running costs compared to larger engines, and suitability for urban driving conditions.
