Volkswagen (VW) produced cars equipped with air-cooled flat four-cylinder engines from the end of World War II to 1978 for the North American market. During its production run, the air-cooled engine was economical but yielded little power.
By the 1970s, the Volkswagen Beetle, Fastback, Squareback, Microbus and Karmann Ghia coupe all featured a 1.5- or 1.6-liter air-cooled engine. As with all all-cooled VWs, the engine featured a horizontal (or flat) four-cylinder engine and two valves per cylinder. It had a 7.50-to-1 compression ratio. The 1.5-liter version delivered 53 horsepower and 78 foot-lbs. of torque --- limited levels even for 1970.
Some VW vehicles --- specifically the Super Beetle, Microbus and Karmann Ghia --- came equipped with a 1.6-liter air-cooled four-cylinder engine with a 7.50-to-1 compression ratio. However, the 1.6 version actually produced fewer horsepower than the 1.5 at 50, with the torque rated identical to the 1.5 at 78 foot-lbs.
Volkswagen did not build its cars for speed but for fuel efficiency. Its vehicles generally yielded about 20 miles per gallon (mpg). The1.5-liter model had a top speed of 78 mph, while the 1.6-liter achieved no better than 81 mph. The 1.6-liter could hit 0 to 50 mph in 14 seconds.
