The 2004 Dodge Sling Shot / Slingshot concept car. The Dodge Sling Shot was based on a smart car, but got better gas mileage and had faster acceleration â up to 45 miles per gallon with 0-60 times of about 10 seconds. Oh, and we drove it.
Both types of dryers function similarly -- air is drawn into the dryer, passes through a heating coil, warms the clothes inside, collects moisture, and is vented out. Gas dryers use gas to create the heat, and electric dryers use electricity. Both types use an electric fan to distribute the heat. Even though both types require a steady stream of electricity, gas models are slightly more efficient.
Uses a hybrid heat pump to recycle wasted heat. Find Ratings. Residential clothes dryers arenât known for their efficiency, which is why theyâre not yet part of the federal governmentâs Energy Star program. Yet LG has announced a dryer that the company claims will be up to 50 percent more efficient than a standard model. The LG DLHX4072V uses a heat-pump exchange system to achieve its target efficiency. Dryers typically lose 20 to 25 percent of their heat through the dryer vent, according to figures from the Environmental Protection Agency, but this model includes components that recycle wasted heat energy.
