The BMW N40 is a DOHC four-cylinder petrol engine which replaced the 1.6 litre versions of the BMW M43.[1] It was produced from 2001-2004 and only sold in several countries, where taxes favoured cars with smaller displacement engines. The N40 was replaced by the BMW N45.
The N40 is based on the BMW N42 engine and uses the same crankcase, pistons and bore size of 841NaN1. The redline is 6,500 rpm.
Unlike the N42, the N40 does not have Valvetronic (variable valve lift). The other major difference is a 91NaN1 reduction in stroke to 721NaN1, which results in a smaller displacement than the N42.
