The new SGE and MGE engines

SAIC-GM joint development and release of new powertrain

Recently, SAIC passenger car company General Motors announced the joint development of its new powertrain, its new powertrain named "CUBE-TECH".

"CUBE-TECH" SAIC passenger cars with General Motors joint development outcomes, including MGE series, SGE series direct injection engine , TST 6-speed dual-clutch transmission, TST 7-speed dual-clutch transmission, and a new generation of engine start-stop systems.

"SGE Series 1.4T engine . "

SGE series engines : SAIC and GM co- developed power technology, a total of 11 engines , displacement from 1.0L to 1.5L, including the three-cylinder, four-cylinder and pressurized and non-pressurized, such as different types of power range from 76 horsepower ( 56 kilowatts) to 167 hp (123 kW) and torque range from 95 Nm to 250 Nm.  Lead production applications including 1.0T models SIDI (Spark Ignition Direct Injection), 1.4T SIDI , 1.5T SIDI turbocharged direct injection engine and other leading products, while the engine structure compatible with hybrid systems and other hybrid fuels.

Application of models: SGE series of representative models 1.4T engine , the first to carry the MG brand cars in the market this year.  The match will be TST 7-speed dual-clutch transmission.  Subsequently, other models and next-generation MG Roewe 550 , Roewe 350 will be equipped with the powertrain.


"MGE Series 2.0T engine . "

MGE series engines : SAIC developed a new generation all-aluminum inline four-cylinder engine products, including displacement of 1.8T, 2.0L, 2.0T, power range from 163 hp (120 kW) to 220 hp (162 kW) and torque range from 200 Nm to 350 Nm.

Application of models: MGE series engine and TST 6-speed dual-clutch transmission will be mainly used in the Roewe , MG brand of high-class models and SUV on the models.

MGE and SGE these two series engine has a lot of the same technical features are the use of advanced high-pressure fuel central arrangement of direct injection , intelligent thermal management, electronically controlled adjustable boost control, DVVT (intake and exhaust valve continuously technology) and other techniques to positive.  In the future, these new powertrain technology In addition to the Roewe , MG brand cars match, will also external output.

SAIC lay real core technologies developed

Yesterday, SAIC Passenger Vehicle Company (hereinafter referred to as SAIC) released a joint development with the new generation of GM full-line direct injection engine, while its new powertrain named "CUBE-TECH". It is understood that the powertrain including MGE series, SGE series cylinder direct injection engine, TST 6-speed dual-clutch transmission, TST 7-speed dual-clutch transmission, and a new generation of engine start-stop system. According to SAIC's plan, from 2015 to 2020, equipped with a whole new generation of powertrain products will reduce overall carbon emissions, power upgrade, improve the economy to achieve the three "over 20%" on the three indicators. To be sure, SAIC has achieved a domestic independent powertrain technology leadership, which also confirms the judgment of the author SAIC, which is a practical car companies.

In my memory, in August 2010, SAIC and General Motors announced the official launch of the joint development of a new generation of high-performance global powertrain, including the series of high-performance small-displacement engine and dual clutch transmission. This is the first Chinese car with large international automobile group in this core technology powertrain joint development and sharing of intellectual property rights on a global scale. And in April of this year, SAIC released SGE series cylinder direct injection engine is the result of this innovative cooperation model. According to reports, SGE series consists of 11 models engine displacement rose to 1.5 liters from 1.0, including the three-cylinder, four-cylinder and pressurized and non-pressurized, such as different types of power range from 56 kilowatts to 123 kilowatts, a torque range from 95 cattle · m to 250 Nm. Lead production application models include 1.0T SIDI, 1.4T SIDI, 1.5T SIDI turbocharged direct injection engine and other leading products, but also to be compatible engine structure hybrid systems and other mixed fuel.

According to my understanding, in fact, before the signing of cooperation with General Motors, SAIC has developed a strategy to create a forward-looking powertrain. According to the strategic implementation plan, SGE series uses strategies developed jointly with General Motors, and MGE will take self-development approach.

SAIC MGE series engine is a new generation of aircraft-grade aluminum inline four-cylinder engines, including the displacement of 1.8T, 2.0-liter and 2.0T, power range from 120 kilowatts to 162 kilowatts, a torque range from 200 Nm to 350 Nm meters. Currently, MGE series of representative models 2.0T engine has been put into use.

SAIC insiders told the author, CUBE-TECH Powertrain release, so SAIC became the center's first direct injection technology will be applied in large-scale synchronization, small-displacement engine car prices. The next five years, SAIC will be fully equipped with brand new products in the next generation powertrain to achieve the "three comprehensive index of more than 20%," that is, "more than 20% reduction in carbon emissions, power increased by more than 20% of the economy to improve more than 20%, "the overall goal of a strong driving force for consumers with ultra-low power smooth cool driving experience, but also to fulfill the energy saving of corporate social responsibility.

All along, the core power technology is the soft underbelly of independent car prices, car prices are independent of each struggled. The SAIC in a pragmatic manner, international perspective, global operations, the first to achieve the technological achievements, and formed a systematic, sustainable development, which not only confirmed the SAIC pragmatic practice true self, but also laid the SAIC leadership in China's automobile industry.

In addition, I also learned that, according to the SAIC's market planning, carrying CUBE-TECH developed a full range of models will be sold in the world, such as Europe, Southeast Asia and so on. In addition Roewe, MG series models match, the SAIC's research results also have external output, the ability to nurture China's auto industry will reach the other car companies increasingly stringent fuel economy standards provide solutions.
