Energy Efficient Technologies

Energy efficient technologies are available now! Many of the vehicles currently on display in dealer showrooms boast new performance-enhancing, fuel-saving technologies that can save you money.

Technology Average
Efficiency
Increase
Engine Technologies
Variable Valve Timing & Lift improve engine efficiency by optimizing the flow of fuel & air into the engine for various engine speeds.
5%
Cylinder Deactivation saves fuel by deactivating cylinders when they are not needed.
7.5%
Turbochargers & Superchargers increase engine power, allowing manufacturers to downsize engines without sacrificing performance or to increase performance without lowering fuel economy.
7.5%
Integrated Starter/Generator (ISG) Systems automatically turn the engine on/off when the vehicle is stopped to reduce fuel consumed during idling.
8%
Direct Fuel Injection (w/ turbocharging or supercharging) delivers higher performance with lower fuel consumption.
11-13%
Transmission Technologies
Continuously Variable Transmissions (CVTs) have an infinite number of "gears", providing seamless acceleration and improved fuel economy.
6%
Automated Manual Transmissions (AMTs) combine the efficiency of manual transmissions with the convenience of automatics (gears shift automatically).
