2018-2019 Buick LaCrosse eAssist – 2,4L Ecotec a rate of 6.4 liters per 100 km

2018-2019 Buick LaCrosse eAssist uses a new technology to General Motors – eAssist, which helps to reduce the fuel consumption of a full-size sedan compared to the current version of the 2018-2019 Buick LaCrosse at 25 percent. The system consists of a 115-volt battery and a 15-kilowatt unit “motor-generator” installed instead of the generator of the internal combustion engine. Fuel consumption 2018-2019 Buick LaCrosse eAssist is 9.4 l / 100 km in the city and 6.4 L / 100 km on the highway.


In conjunction with the four-cylinder 2.4-liter Ecotec engine with direct injection and a six-speed automatic transmission of the next generation, eAssist system uses battery power to optimize the operation of the internal combustion engine 2018-2019 Buick LaCrosse in different situations.

eAssist 2018-2019 Buick LaCrosse

  • generation system up to 15 kW braking power
  • Adding up to 15 horsepower during acceleration
  • Automatic engine shut off when the vehicle is stopped
  • Automatic shut-off the fuel supply during deceleration
  • Intelligent charge / discharge of the battery system

2018-2019 Buick LaCrosse with eAssist technology also has improved aerodynamics parameters optimized for fuel economy, tire with less resistance and active airflow control, which improves the aerodynamics and engine cooling. Electronically operated blinds on the lower grille 2018-2019 Buick LaCrosse at high speed close, providing less resistance and consequently fuel consumption, while reducing the speed of opening, allowing the engine cooling.

“2018-2019 Buick LaCrosse was the first in its segment combining four-cylinder engine with six-speed gearbox and is currently the leading vehicle with the technology of the new standard eAssist”, Schwegman said. “It is important to note that at the 2018-2019 Buick LaCrosse with eAssist system equipped with a standard four-cylinder engine.”

At the 2018-2019 Buick LaCrosse eAssist dashboard with the speedometer mounted ECO gauge that shows the driver how to drive as efficiently as possible and the battery sensor, which also shows in what mode the electric motor / generator.

The system also allows, under certain conditions, completely block the flow of fuel Ecotec engine 2018-2019 Buick LaCrosse, which further saves fuel. By pressing on the accelerator by the driver, for the rapid and smooth acceleration in the mode where the fuel supply is blocked by the motor-generator continues to rotate with the motor. And when the 2018-2019 Buick LaCrosse stops the motor-generator unit brings the internal combustion engine to a smooth stop.

“The battery is designed to provide assistance to the internal combustion engine 2018-2019 Buick LaCrosse, rather than storing energy for the electric motor,” Poulos said. “It is not a replacement for an internal combustion engine, and an auxiliary device, which greatly increases productivity and reduces fuel consumption.”

The electric motor / generator eAssist system is installed on the internal combustion engine instead of the generator up and running with a belt drive. To increase productivity and efficiency 2018-2019 Buick LaCrosse compact high performance asynchronous motor is equipped with a liquid-cooled.

2018-2019 Buick LaCrosse eAssist – a full-size luxury sedan with a fuel consumption of 6.4 liters per hundred kilometers, while maintaining the performance and cost about 30 thousand dollars (the exact amount will be announced later).
