New GM 1.6-L diesel compliant with Euro 6 emissions regs

  • 25-Jan-2013 10:27 EST

To appear first in Opel and Vauxhall models, GM's new 1.6-L turbodiesel is claimed to have class-leading refinement, a high power/torque density, fuel consumption reduced by up to 10%, and complies with future Euro 6 emissions requirements.

GM's Opel brand recently unveiled a new 1.6-L four-cylinder turbodiesel engine that represents the second of GM's three new downsized engine families to be introduced after the recent gasoline 1.6-L SIDI Ecotec. The 1.6-L CDTI Ecotec diesel will replace 1.7-L engines and certain lower powered versions of the 2.0-L range. Featuring closed-loop combustion control and an aluminum block, the new engine is GM's first diesel to comply with future Euro 6 emissions requirements. The diesel will be available in a variety of power outputs across several car lines, led by Opel and Vauxhall applications. Class-leading NVH, high power/torque density, and low fuel consumption were the main development objectives of the global engineering team based in Turin, Russelsheim, and Pontiac. Maximum power and torque have been increased in the initial offering, compared with the outgoing 1.7-L engine, to 136 hp (101 kW) and 320 N·m (236 lb·ft). Fuel consumption has been reduced by up to 10% compared with similar output 2.0-L diesels. According to Dr. Thomas Sedran, Deputy Chairman of the Opel Management Board, “Our new 1.6-L diesel will set benchmarks for refinement, performance, and environmental compatibility." It is part of a roll-out of 13 new powertrains by 2016. Production begins this spring at GM's Szentgotthard, Hungary, engine plant that also builds the new 1.6-L gasoline engine.
