![]() With the end of the Chevy Cobalt S/C SS and Saturn Ion Red Line, the LSJ was discontinued after 2007. The LSJ shares many of its components with the LK9 such as: piston cooling jets, oil cooler, pistons, connecting rods, crankshaft, oil pan, sodium-filled exhaust valves and cylinder head. The LSJ is a supercharged version of the LK9 Ecotec 2.0 L (1,998 cc) with an Eaton M62 Roots-type supercharger and air-to-liquid intercooler. LSJ Ecotec LSJ engine in a 2006 Saturn Ion Red Line It features an 86 mm (3.4 in) bore and stroke and a 9.5:1 compression ratio. The reinforcements, turbocharging, intercooling, internals, dual overhead camshaft, and such were developed by GM Powertrain Sweden (Saab Automobile Powertrain). The timing chain and timing gears are also new, along with Saab's Direct Ignition system. All vehicles using this engine feature Saab's Trionic 8 (T8) engine management system as well as a revised valve train. The exhaust valves are liquid sodium-cooled. The engine features a five-bearing forged steel crankshaft, strengthened connecting rods, redesigned pistons, piston oil cooling jets, reprofiled camshafts and an integrated oil cooler. LK9 is a turbocharged 2.0 L (1,998 cc) version of the L850 (86 mm bore) series Ecotec utilizing an all-new reinforced sand cast aluminum cylinder head and upgraded internal components. This engine is also known as B207 when used by Saab and Z20NET by Opel for use in the Vectra C and Signum. The current Ecotec line is manufactured in Tonawanda, New York. The first engine in the Ecotec Gen I line-up was Ecotec 2.2 L61, introduced in May 1999. Vibration is reduced with twin balance shafts. The engine uses aluminium pistons and cast iron cylinder liners. Much of the development work on this project was carried out by Lotus Engineering, Hethel, United Kingdom. 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. The Ecotec engine is a DOHC 4-valve design with a lost foam cast aluminum 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. GM intended this new Ecotec to become its global 4-cylinder, and it has already fully replaced their OHV I4 line. The name was already used for the Opel GM Family II engine, Family 1 and Family 0 ranges. Then in 2020, the line was discontinued with various other models taking over for each of the regions it was being marketed in.The ' Ecotec' name was adopted in 1994 for the new generation of Family II engines (2000 in North America). In 2013 this Cobalt model was imported into Russia for 2 years, manufactured in a plant in Uzbekistan.

Warning lights and dashboard symbols built into both generations are relatively the same as they used similar platforms. This was slightly bigger and was the same that was used under the Opel Mokka and the Chevrolet Trax. The second-generation model was only available in Brazil and was built on a totally different platform called the Gamma II. ![]() Safety-agency HTSA rated the Cobalt pretty well with many 4 and 5 out of 5-star ratings across the board apart from in the event of a side collision where it rated "poor".Įventually, the car was replaced by the Cruze in North America which was based on the newer Delta II platform. It sat on the same shared Delta platform as the Opel Astra and the Chevrolet Equinox - a mix of compact and compact crossover SUVs. General Motors decided to revive the model and start producing it in their Brazil assembly plant for the domestic market.ĭuring its time as a North American line, it was also sold by a partner brand Pontiac as the G4, the G5 and also as the G5 Pursuit. It ran from the 2005 model year through to 2010 in the USA but in 2012 it reappeared in South America. The Chevrolet Cobalt only had a short-lived existence in the North American automobile market.
