2012 Honda Civic Hybrid: Upgraded Over Last Year'S Model

Author: Administrator
The new 2012 Honda Civic Hybrid is now using a lithium-ion battery and its fuel economy has risen from 41 mpg to 44 mpg. The Civic Hybrid is today in second-place for energy economy for cars that now rely on fossil fuels. This excellent improvement in gas economy makes it greater than the Lexus CT 200h. It really is regarded as the most fuel-efficient 4 door on the market today.

The Integrated Motor Assist is going to be the fifth output hybrid powertrain system that the 2012 Civic Hybrid uses, which is thin, pancake like electronic motor/generator. Just like the devices employed in Ford and Toyota hybrids, Honda's system assists the gasoline engine by being contained between the transmission and engine. The electric powered motor helps the gas engine however it can be powered by electric by itself for short distances. All engine parts still move even when the car runs temporarily on electric power. When the car quits, the engine shuts off just like other hybrids.

The new 2012 Civic Hybrid includes a larger gasoline engine, combined with the shift to lithium-ion batteries. The 1.3-liter engine has been increased to a 1.5-liter four-cylinder, however the combined horsepower of the electric and gas is going to be unchanged. As a result of larger displacement, the engine runs at a lower RPM which translates into a quieter ride as the electric motor is used more. Honda achieved optimal efficiency by fine-tuning the hybrid system like improving the motor output from 15kw to 20kw. Heat is managed more efficiently by using plastic spacers and equally spaced coils and magnets. The motor has increased to a reasonable 23 horsepower, which is up from 20 horsepower.

The 20-kw Li-ion battery is actually a big improvement over the nickel-metal hydride battery that was used in the previous model, providing an extra 5kw of power with 30% less weight. With the battery remaining 35% better and the IMA system being more powerful, the car is able to cruise at low speeds on pure electricity. There were reliability issues related to the battery so the switch to lithium battery should resolve this problem. Yet another enhancement in the IMA set up is the continuously variable transmission. The transmission works similar to a 10-speed bicycle which comes with a drive pulley and a driven pulley which are linked with a steel belt. It is a mix of a manual transmission and also a conventional geared automatic transmission.

With sound enhancements in fuel-efficiency and battery, the 2012 Civic Hybrid has certainly earned its awards. It is definitely giving the Prius a run for its money.
