Looks and Smarts
By all accounts, Honda not only designed the heck out of the Civic, they engineered it to the extreme. The Civic hybrid breaks the 50-mark for both highway and city EPA numbers, and qualifies or Advanced Technology Partial Zero Emissions status in all 50 states.
How did Honda achieve more power and efficiency, and cleaner emissions, all at once? Examples:
Deactivation down to zero
There are a few cars on the road that save gas by de-activating cylinders when they are not needed. The Civic Hybrid, in certain cruising modes, can deactivate ALL of its cylinders. During this time, the electric motor alone powers the vehicle. At other stages of acceleration and cruising, Honda’s variable valve system allows cylinders to open and close for the right mix of performance and efficiency.
Smaller more powerful powertrain
Honda is on the fourth generation of its integrated engine/motor design. The Civic combines a 1.3 liter iVTEC 4-cylinder engine with a 20-hp electric motor to deliver a total of 110 hp. The new powertrain is 20 percent more powerful and five percent lighter than the previous model.
Reduced friction
The Civic utilizes friction-reducing efficiency-boosting engine design, such as aluminum die-cast pistons, ion-plated piston rings, and smoother surfaces on the cylinder walls.
More efficient combustion
The Civic Hybrid uses eight spark plugs that operate in two modes: sometimes they fire one after the other, with the plug situated near the intake valve firing first and the exhaust plug firing later. Flexibility with the firing order allows for a more complete combustion of fuel in the cylinder.
