History

Production began in late 2012 at Szentgotthárd, Hungary.[1][2] The engine features Start/Stop and reduces fuel consumption and CO2 emissions by 13 percent comparing to the predecessor, while maintaining Euro 6 emissions standards.[3]

A turbocharged Eco variant delivering 170 PS (125 kW; 168 hp) @ 4250 rpm and 260 N⋅m (192 lb⋅ft) @ 1650-4250 rpm (overboost 280 N⋅m (207 lb⋅ft)) has been introduced at 2012 Moscow International Automobile Salon (MIAS); a Performance version with maximum torque 300 N⋅m (221 lb⋅ft) and peak power 200 PS (147 kW; 197 hp) will also be available. Each version features unique turbine aerodynamic, and aggressive boost strategies improve low-end torque.[4]

The high-performance turbocharged 1,598 cc (1.6 L) engine with central direct injection has 79 mm × 81.5 mm (3.11 in × 3.21 in) bore and stroke, with cylinder pressure of 130 bar (1,900 psi) and compression ratio of 9.5:1 for Performance version and 10.5:1 for Eco version. It uses a grey cast-iron block with die-cast aluminum bedplate, aluminum cylinder head, chain-driven DOHC valvetrain with hydraulic tensioners, dual continuous variable cam phasing, and forged steel crankshaft. The engine has twin balance shafts and specially designed cam cover to improve NVH, while optimized compressor geometry, acoustic resonators and overall air handling help reduce noise by 2 dB. Centrally placed injector allows optimal operation in both stratified and homogeneous charge ignition. Optimized main bearing journal diameter, roller cam followers, and PVD coated piston rings reduce friction.[4]

Starting in 2013, the engine began to replace turbocharged 1.6 L Family I Ecotec engine in Opel cars, and in 2014-2015 it will replace naturally aspirated 1.6 L and 1.8 L Family 1 engines in Chevrolet cars. Starting with 2020 model year, this engine is no longer available for the United States market, due to Buick Cascada and Chevrolet Malibu Hybrid being phased out because of low sales and high importation taxes from Europe.
