The new generation of the iconic Golf, ed made by Volkswagen, there will feature the cylinder deactivation system for the four-cylinder TSI engine, seek which will shut down two “chambers” in order to reduce the fuel consumption and CO2 emissions.
The technology already exists on the market and it’s currently implemented to V8 and V12 engines by automakers like General Motors, but the first unit equipped with this system was made by Cadillac under the V-8-6-4 name, deactivating cylinders in different configurations.
The Japanese at Mitsubishi were the first ones to equip a 1.4 liter four-cylinder engine with this technology in 1982, wearing the Modulated Displacement name and in 1996 they dropped it from reasons unknown yet.
According to Volkswagen, the Golf’s TSI engine will lose between 25 and 75 Nm when the system will deactivate two cylinders, and it will activate all four under 1.400 rpm and over 4.000 rpm, reducing the fuel consumption by 0.4 liters per 100 kilometers, but when driving with a constant 50 km/h, the German automaker says that the system will save one liter of fuel every 100 km.
Volkswagen will later implement this system to its Polo and Passat models and later, more VW sub-brands will benefit from it.
