The Volvo D5 is a type of turbocharged Diesel engine developed by Volvo Car Corporation for use in its passenger cars.

It is an all Aluminium 5 Cylinder (engine) engine with 20 valves and double overhead Camshaft. It has a Variable geometry turbocharger turbocharger, Common rail direct injection and cooled exhaust gas recirculation.

There are two generations of D5 engines. The first generation was introduced in 2001; the second generation was introduced in 2005. The second generation has a reduced compression ratio, a water cooled VNT turbocharger with a bigger compressor and an electric servo motor to adjust the vanes, an improved Exhaust gas recirculation system, a throttle valve, revised intake and exhaust ports and a newer generation of common-rail direct injection with improved injectors.

Volvo has a special version of the D5 for use in the S40, V50 and C70 models that produces 180 Horsepower and 350 Newton metre of torque. The engine compartments of these cars are smaller so the engine has a different intake manifold and other parts.

The D5 is also offered as a marine engine by Volvo Penta. The output is 110 hp (82 kW) at 3,000 rpm, 130 hp, 160hp, 190 hp (140 kW) at 4,000 rpm and it is coupled to a duoprop I/O system.
