The GM Ecotec engine , also known by its codename L850 , is a family of all-aluminium inline-four engines , displacing between 1.2 and 2.5 litres. Confusingly, the Ecotec name was also applied to both the Buick V6 Engine when used in Holden Vehicles, as well as the final DOHC derivatives of the previous GM Family II engine ; the architecture was substantially re-engineered for this new Ecotec application produced since 2000. This engine family replaced the GM Family II engine, the GM 122 engine , the Saab H engine , and the Quad 4 engine . It is manufactured in multiple locations, to include Spring Hill Manufacturing , in Spring Hill, Tennessee , with engine blocks and cylinder heads cast at Saginaw Metal Casting Operations in Saginaw, Michigan .
45-1090: The " Ecotec " name was adopted in 1994 for the new generation of Family II engines (2000 in North America) . The name was already used for the Opel GM Family II engine, Family 1 and Family 0 ranges. GM intended this new Ecotec to become its global 4-cylinder, and it has already fully replaced their OHV I4 line. The Ecotec engine is a DOHC 4-valve design with a lost foam cast aluminium block and head (L850 for 86 mm bore applications, and L880 for 88 mm bore), designed for displacements from 1.8 to 2.4 L. Development began in 1994, by an international team of engineers and technicians from Opel 's International Technical Development Center in Rüsselsheim , Germany, GM Powertrain in Pontiac, Michigan , and Saab in Södertälje , Sweden. Much of
90-490: A rotacast aluminium-alloy (A356T6) cylinder head with sodium-filled exhaust valves. Maximum engine speed is listed at 7000 rpm. A successor to the LTG debuted in the 2019 Cadillac XT4 and the 2019 Cadillac CT6 . The LSY adds Active Fuel Management and a start-stop system , putting more priority to fuel economy than performance. Peak output is lower than the LTG, but is achieved at lower rpm for both power and torque. Bore

A turbocharged direct-injected (redubbed Spark Ignition Direct Injection ) Ecotec was introduced in
360-464: A coolant capacity increase of 0.5 liters. In December 2008, GM released a Turbo Upgrade Kit for the LNF engine which increases horsepower to 290 hp (220 kW) and torque to up to 340 lb⋅ft (460 N⋅m), depending on the model. The kit retailed for $ 650 and includes remapped engine calibration and upgraded 3 MAP sensors. The kit is covered by the cars' existing GM warranties. Boost pressure
