General Motors has developed two brand-new engines for vehicles marketed in Europe and other regions, a 1.4-liter Turbo gasoline unit and a 1.6-liter Turbo natural gas unit. Starting off with the new 1.4-liter turbocharged 4-cylinder engine, it will be offered in vehicles worldwide starting in 2010 with outputs ranging from 120 hp to 140 hp and torque values of 175 to 200 Nm.
It is estimated that this unit will deliver an approximate 8% improvement in fuel consumption compared to a higher displacement naturally aspirated engine with similar output and will be EURO 5 compliant. The 1.4 Turbo variants will be manufactured at the GM Powertrain assembly facility in Aspern, Austria.
The 1.6-liter Compressed Natural Gas (CNG) turbocharged 4-cylinder engine that generates an estimated output of 150 hp and 210 Nm of torque will be introduced in the Opel Zafira minivan in 2009. The 1.6-liter CNG Turbo features a 25% lower CO2 value than a comparable gasoline engine and it will be produced in the GM Powertrain assembly facility in Szentgotthard, Hungary.
