Helmut Werner Bönsch, BMW's director of product planning, and Alex von Falkenhausen, designer of the M10 engine, each had a two litre engine installed in a 1600-2 for their respective personal use. When they realized they had both made the same modification to their own cars, they prepared a joint proposal to BMW's board to manufacture a two litre version of the 1600-2.
The 1990 cc engine was made available in 1968 in two states of tune: the base single-carburetor 2002 producing 100 bhp (75 kW; 101 PS) as in the 2000 and the 2000 C and the dual-carburetor high compression 2002 ti producing 120 bhp (89 kW; 122 PS) as in the 2000 TI and the 2000 CS. The 2002 Automatic, with the base engine and an automatic transmission, became available in 1969.
In 1971, the Baur cabriolet was switched from the 1.6 L engine to the 2.0 L engine to become the 2002 cabriolet, the Touring hatchback version of the 02 Series became available with all engine sizes available in the 02 Series at the time, and the 2002 ti was replaced in by the 2002 tii with the fuel injected 130 bhp (97 kW; 132 PS) engine from the 2000 tii. offering a top speed of 185 km/h (115 mph). The 2002ti (touring Internationale) is very rare, even more so than the 2002 turbo, as very few of these cars still survive. The 2002ti was also very successful in racing and Hans Stuck won the Nurburgring 24-hour race in 1970, but the car also won many hill-climbs and rallies. A 2002 tii Touring model was available throughout the run of the tii engine and the Touring body, both of which ended production in 1974.
