<!-- specifications are for the "first" Volkswagen engine, not the 985cc KdF engine -->The Volkswagen air cooled engine
is an air-cooled boxer engine
with four horizontally opposed cast iron cylinder
, cast aluminium alloy cylinder heads
, magnesium crankcase
, and forged
and connecting rods
Variations of the engine were produced by Volkswagen plants
worldwide from 1936 until 2006 for use in Volkswagen's own vehicles, notably the Type 1
, Type 2
, Type 3
, and Type 4
. Additionally, the engines were widely used in industrial, light aircraft and kit car applications.
Type 1: 1.1–1.6 litres

, the first Volkswagen Transporters
(bus) used the Volkswagen air cooled engine, a 1.1 litre
-rated 24 kW (24 PS, 24 bhp), air-cooled four-cylinder "boxer" engine
mounted in the rear
. The 22 kilowatt (29 PS; 29 bhp) version became standard in 1955, while an unusual early version of the engine which developed 25 kilowatts (34 PS; 34 bhp) debuted exclusively on the Volkswagen Type 2
in 1959. This engine proved to be so uncharacteristically troublesome that Volkswagen recalled all 1959 Transporters and replaced the engines with an updated version. Any examples that retain that early engine today are true survivors - since the 1959 engine was totally discontinued at the outset, no parts were ever made available.
