Chrysler LLC said Monday it has extended its $2.99 gas incentive plan for an additional month to July 7. The move was made in response to dealer and customer demand for additional time.

"Customers and dealers across America have told us they like the gas guarantee incentive option, so we are providing a second month for shoppers to take advantage of it," said Jim Press, Chrysler LLC vice chairman and president.

The company's "Let's Refuel America" plan caps gas prices at $2.99 a gallon for three years, up to 36,000 miles, for people who buy or lease a Chrysler, Jeep or Dodge vehicle.

The gas program was launched on May 7, and has generated increased traffic into Chrysler's dealerships and Websites, the company stated.

The highest take rates for the program have been on the new Dodge Journey crossover, Dodge Caliber, Dodge Avenger and Chrysler Sebring sedan, according to Chrysler.

"The most incremental incentives in this gas program are on the company's most fuel-efficient vehicles, which typically do not have this level of incentive available," Press said. "Our customers who buy smaller vehicles put great value on being protected against rising gas prices."

From a geographical perspective, the highest take rates have been in the states of California, Connecticut, Indiana, Ohio, and Washington, the company said.
