Wayne Gerdes set a new Guinness World Record for fuel efficiency by driving a 2023 Toyota Prius LE from Los Angeles to New York City, achieving an average of 93.158 miles per gallon over 3,211.7 miles. This surpasses the previous record of 76.6 mpg set by a Kia Niro in 2016. The journey included extreme conditions such as high temperatures in the Mojave Desert and elevations up to 7,000 feet. Toyota emphasizes that this achievement isn't typical but showcases the Prius' engineering excellence. Gerdes, an experienced hypermiler, highlighted the meticulous planning and adaptive driving strategies needed for the record. The Prius' impressive mileage per tank far exceeds Toyota's quoted range, reinforcing its status as a highly efficient hybrid vehicle.
