The B18 is a 1.8 L inline four cylinder overhead valve automobile engine produced by Volvo from 1961 through 1968. A larger 2.0 L derivative called the B20 debuted in 1969.

Despite being a pushrod design, the engines can rev to 6,500 rpm.[citation needed] They are also reputed to be very durable. The world's highest mileage car,[1] a 1966 Volvo P1800S, traveled more than 4,890,993 km (3,039,122 mi) on its original B18 engine.[2][3]
