Honda's first production V6 was the C series; it was produced in displacements from 2.0 to 3.5 liters. The C engine was produced in various forms for over 20 years (1985–2005), having first been used in the KA series Legend model, and its British sister car the Rover 800-series (and Sterling). All C engines share in common a 90-degree V-angle from bank to bank, common cylinder block bore centers, and four valves per cylinder. It is an all-aluminum design, and uses timing belt-driven single or dual overhead camshafts; the water pump is also driven by the timing belt.
