TOKYO - The Mitsubishi Pistachio is the world's first gasoline-powered '3-liter' car, going 100 kilometers on three liters of gasoline, Mitsubishi Motors Corp. said.
That is 70.6 mpg. Other 3-liter cars have used either a diesel engine or a hybrid engine plus an electric motor.
The Pistachio, which will go on sale in Japan this year, has a 1.1-liter, inline four-cylinder, gasoline direct-injection engine.
The engine stops automatically when the car is idling.
The mileage claim is based on Japan's so-called 10-15 fuel-economy tests, which simulate highway cruising, city driving and idling in stalled traffic. In that test, idling accounts for 15 percent of total fuel consumption for conventional gasoline engines. The mpg result is typically higher than would be expected in a U.S. test.
Turning off the engine when idling cuts that figure to 10 percent for the Pistachio.
Also enhancing mileage is the car's weight: Less than 2,200 pounds.
