Today is July 7, or 7/7, or Sevens Day, the day we celebrate the indomitable Mazda RX-7. Since this year marks the 100th Anniversary of Mazda let’s honor the day with the very first RX-7, the 1978 SA22C, in its iconic Mach Green color. As mentioned in the second installment of our Mazda centenary retrospective, This futuristic little sports car came right out of the gates with rotary guns blazing, winning the 24 Hours of Daytona in its inaugural year, then following up with a win at the Spa 24 Hours in 1981. It paved the way for everything from the Le Mans-winning 787B to the legendary FD3S. It’s truly one of the all-time greats. Happy RX-7 Day from JNC!
