Mazda Motorsports has retained all four of its full-season drivers for the 2016 IMSA WeatherTech SportsCar Championship season, with Jonathan Bomarito, Tristan Nunez, Joel Miller and Tom Long all returning to the factory Prototype squad.

Miller and Long will share the wheel of the No. 70 car, with Bomarito and Nunez set to drive the newly renumbered No. 55 entry, which pays homage to Mazda’s 787B that won the 24 Hours of Le Mans in 1991.

“We couldn’t be happier that each of our Mazda Prototype drivers return to the team for 2016,” said Mazda Motorsports director John Doonan.

“In addition to being top-notch drivers, we couldn’t ask for a better group of gentlemen to represent the Mazda brand in the premiere level of our Mazda Road to 24 sports car program.

“Each of them has a never-ending positive attitude that doesn’t waver. We expect more success on the race track this year, and we believe we have four racers who can bring those results to Mazda.”

Additional drivers for the four Tequila Patron North American Endurance Cup races, including the Rolex 24 at Daytona, will be revealed at a later date.
