The Hertz Corp. has updated its U.S. rental car fleet with a refresh of 2015 model year cars ranging from sedans and SUVs to luxury models.

As of April 30, Hertz had added over 235,000 new vehicles from a variety of manufacturers, according to the company.

The fleet refresh includes a selection of 2015 models from Chrysler, Fiat, Ford, General Motors, Hyundai, Infiniti, Kia, Mazda, Mercedes Benz, Mitsubishi, Nissan, Toyota, Volkswagen and more. Some of the vehicles include the Nissan Altima, Toyota Camry and Chevrolet Cruze.

In its Dream Cars Collection, the new 2015 models include the Mercedes Benz C-Class, the Porsche Macan and the Mercedes CLA45 AMG.

"We are thrilled to bring customers across all of our brands not only a wide variety of vehicles but better vehicle options,” said Tom Frese, senior vice president, Fleet and Procurement. “With this refresh, we are continuing to diversify our fleet with a mix of models that includes some of the safest, most fuel-efficient and top-rated vehicles in the market. We are working hard to put our renters only in the best of what's available, while meeting a range of customers' tastes and needs."

Additionally, over 80% of Hertz's vehicles have a minimum fuel-efficiency rating of 28 highway miles per gallon, says the company.

"At this point, we have delivered a substantial number from our 2015 fleet purchase to our U.S. rental locations,” added Frese. “We expect that by mid-2015 we will have greatly improved our fleet's mileage profile, restoring it to our historic low levels. Safety and reliability remain top priorities, and we're working hard to ensure our entire fleet reflects this."
