lithium ion battery pack 2018 Buick LaCrosse eAssist Hybrid

Today, electrified may be a hot word for the automotive industry, but for more than a decade, GM has been offering a variety of hybrid cars.
The Buick Department launched the first such car as early as 2012: Junyue eAssist, a hybrid version of its large sedan that lasted 2016 years. When the third-
A generation of Junyue was released at a price of 2017, and the technology was not available in the order, but Buick re-launched the hybrid at a price of 2018. The four-
Now it's the cylinder eAssist-
Primary power unit.

However, the tilt of the power system keeps hockey low.
Walking around Junyue, there are only four badges in front of you: Buick III
The shield logo on the grille and the center of the shield, the Buick on the left side of the shield and the Junyue on the right.
Nothing else on the back or side of the body indicates that the car has hybrid technology under the skin.
Even the trendy color options of bright green, chrome yellow or blue are not available.
Our test car is white with chrome wheels.
Elegant but traditional.
The same aesthetic is also carried out indoors.
To be different, there is no strange dashboard arrangement, no strange pattern or color decoration, no odd position shifters.
One thing that suggests that some environmental protection is happening is a small digital leaf on the right side of the instrument group;
It acts as a needle on 1 m between ACCEL and BRAKE.
Given how basic these tasks are in any car, it seems silly to see these tags, but it indicates two areas where the eAssist system works.
This branch of the GM Green Machine family dates back to Saturn-

Green wire belt-alternator-
(BAS) system.
Since then, BAS technology has been applied to many General Motors and has been continuously improved over the years, eventually being sold in the form of eAssist.
It uses automatic stop/start-up and a small amount of electric assist and regenerative braking to improve fuel economy.
In hockey, the hybrid system consists of a 2. 5-liter inline-
4 gasoline engines, 1 electric motor/generator and 24-cell 0. 5-kWh lithium-
Ion battery pack.
The motor, which GM calls the motor generator unit (MGU), replaces the conventional alternator, which is driven by a belt or belt depending on its mode.
The regenerative brake collects energy and MGU converts it into electricity and stores it in the air
Cooling the battery pack.
When Hockey stops, the gas engine is turned off and the battery powers other functions of the car, such as infotainment and HVAC systems.
Then, when the brake is released, it is used to restart the engine, and it can also provide additional torque when the driver presses the throttle.
Buick claims that it provides 9% of the torque compared to the previous Junyue eAssist, and in addition, the overall size of the system is smaller and the packaging is more efficient.
Even so, the battery will hit the trunk space.
While the rear seat folds down, the rectangular bump on the floor of the trunk runs through the passage-
By opening the cabin of the car.
The loss of cargo space is only 1 cubic foot (14 to 15), but the interruption of the loading layer is more unfavorable than those shown by these figures.
Nevertheless, it is less invasive than the previous hockey eAssist battery pack.
2018 LaCrosse eAssist is EPA-
Rated on 25 mpg cities, 35 highways and 29 joint highways, only slightly higher than the 2016/28 rating for the 24/35 model.

The driver model in 5 is 60. 9 seconds;
The AWD model is a little faster at 5. 8.
Therefore, the increase in fuel economy is at the expense of acceleration.
But hybrid systems are difficult to detect at least in operation.
The only sign that the power system is trying to save gas is the stop/start function, which has now become the standard for many non-hybrid cars.
For few people affectionately recall the time when the sofa on the wheel was wandering the street, Hockey was a nostalgic explosion from the past.
The lacrosse, which is nearly 200 inch long, is huge and it drives like it does.
The turn is slow and there is no indication of what is going on under the car, and when turning, it feels like the body is sitting on the Bosu ball.
However, it is not floating, but purposeful and controlled.
The disconnect between the road and the driving experience does create an extremely quiet cabin.
The power system is smooth and quiet, the road noise is effectively blocked, and the bumps are easily released without disturbing the ride.
Considering the proximity of our test car, the interior doesn't feel as upscale as it should be$45,000 price.
The dashboard was clean and tidy and well organized, but due to the huge central console taking up space, creating a limited feel for drivers and front-row passengers, the layout caused some complaints.
The back seat of this Buick is casual.
The clearance and legroom at the back are large, the seats are luxurious and the ride is soft.
We would be ecstatic if our Lyft driver stopped in one of the cars.
Hockey eAssist is really a good choice thanks to its impressive petrol mileagetime taxi.
For those who don't like the sacrifices that hybrid cars bring, this Buick offers extra miles in a comfortable, low-key package.
