Kia’s Niro EX just took the Guinness World Record for lowest fuel consumption driving coast-to-coast in a hybrid car averaging 76.6 mpg.

The hybrid crossover was driven 3,715.4 miles from Los Angeles City Hall to New York City Hall. Well-known “hyper miler” Wayne Gerdes of Carlsbad, Calif., and co-driver Robert Winger of Williamsburg, Va., used only 48.5 gallons or 4.1 tanks of gas.

“We’re extremely pleased with the Niro’s record-breaking performance,” said Orth Hedrick, vice president, product planning Kia Motors America. “We set out to build a vehicle that offers real-world utility, great looks and fantastic mileage, and setting the Guinness World Record title confirms our achievement.”

Kia says the Niro utility vehicle fits the “Urban Crossover Hybrid Vehicle” category. It’s Kia’s first dedicated hybrid electric vehicle, and was designed to “bridge the gap between outstanding fuel economy and compact crossover usefulness.”

Its official EPA mileage rating for the standard FE package is 52 mpg highway, 49 city, and 50 mpg combined. Kia doesn’t list the EX model’s mpg, which was used in the cross-country trip. How the drivers were able to make the leap to 76.6 mpg in highway driving wasn’t explained, but a safe guess is they utilized every hyper miler technique feasible.

It all makes for a nice press release, but don’t expect to repeat the performance, unless you also are prepared for extreme austerity measures in your driving style.

That said, Kia notes the Niro does come with a new “dedicated eco-car platform and a unique hybrid system.” The Korean automaker designed the hybrid system to offer what it calls a more dynamic and engaging driving experience.
