Do you want a midsize sedan that effectively reduces your fuel costs while helping you save the environment? Why not try the Chevrolet Malibu Eco? The Chevrolet Malibu Eco is the perfect choice for drivers who want to save money amidst the rising pump prices. The secret? Malibu Eco features a unique highly advanced technology.
Chevy installed the Malibu Eco with a state-of-the-art electric power assist steering system that allows drivers to save fuel by 2.5% compared to conventional hydraulic steering systems.
The Malibu Eco’s electric power assist steering saves fuel by consumer power only during steering maneuvers, in contrast to hydraulic pumps that constantly drains engine power. The Malibu Eco’s electric power assist steering system also cuts carbon dioxide emissions and maintenance cost by getting rid of the need to dispose hydraulic fluid.
The system continuously measures the driver’s steering input and adjusts to different road conditions. The system also helps counteracts small directional shifts as results of uneven road surfaces or crosswinds. The system allows drivers to have more control of the car in low-speed parking as well high-speed travels. A driver could choose between different driving modes like “comfort” and “sport” in some models.
With the electric power assist steering system, a driver could save around 12 gallons annually, or about 120 gallons in a 10-year life. Chevrolet Malibu Eco has an EPA-estimated fuel economy rating of 25 mpg in the city and 37 mpg on the highway. According to Mark Meyers, General Motors global vehicle performance manager, the company intends to install electric power assist steering systems in than half of all Chevrolet, Cadillac, Buick and GMC vehicles by the end of the 2013 model year.
The eAssist system is paired to the four-cylinder 2.4-liter direct-injection Ecotec engine and the next generation automatic six-speed transmission. Proof of how efficient the engine is the electronic throttle control, continuously variable intake and exhaust timing direct injection, and the dual-overhead cams. In addition to being efficient, it is lightweight as well with both the cylinder block and the cylinder head made of lightweight aluminum.
The power of this engine is estimated to be at 180 hp (134 kW). Additionally, a version of this engine was awarded in 2012 with Ward's Ten Best Engines. In many standard vehicles, energy is generally lost when braking. But with the eAssist system, the new Chevrolet Malibu ECO is able to recover at most 15 kW of the energy and then use it in order to recharge the vehicle’s lithium-ion battery. In certain situations involving deceleration, this same system shuts down the fuel delivery and this helps improve the fuel economy even further.
While the vehicle is in fuel shut-off mode, its motor-generator unit remains to spin on its engine. This allows for a smooth and instant take-off power especially when the driver is pressing on the model’s accelerator.
Through the engine and the transmission, the eAssist system is also able to utilize all of the power that is stored inside the lithium-ion battery and thus helps provide that important electrical boost in certain driving conditions. The combination also helps optimize the operation of the engine and the transmission it is paired to. Capable of 115 volts, the lithium-ion battery plus the 15-kW motor generator unit improves fuel economy through a number of methods.
There is of course the regenerative braking where it can recover a maximum of 15 kW to recharge the battery. There is also the intelligent discharge and charge of its high-voltage battery. Helping the Malibu ECO save fuel as well is the fuel cut-off when decelerating and reaching a complete stop. When stopped, it makes use of electricity rather than gasoline and even has the smooth and automatic engine start-stop function.
