THE CLK320 was among the first Mercedes-Benzes to be powered by the new generation modular 90-degree V6 engines. This family of engines can easily vary in capacity and between V6 and V8 configuration, hence the "modular" tag. The V6 3.2-litre engine produces a maximum speed of 240km/h, and accelerates from 0-96 km/h in 7.1 seconds. The Active Service System can extend oil-change intervals from 15,000km up to 20,000km. The engine's platinum spark plugs require replacement every 100,000km.
