There’s some serious tech packed into the 2019 Nissan Altima. Take, for instance, its engine. The 2.5-liter unit is something special in that it benefits from a special manufacturing process that usually only finds its way into the engines of supercars.
The engine block of the 2019 Nissan Altima benefits from a cutting-edge mirror bore process that serves to enhance efficiency and reduce friction. Overall, the elimination of bulky cylinder liners allows the motor to operate more smoothly. The treatment was first used in the Nissan GT-R and now, thanks to the Decherd assembly line, it’s made its way to the Altima. As a result, it’s now the highest volume application of the tech at Nissan—Decherd’s team assembles a motor every 19 seconds and can pump out as many as 1.4 million units a year.
"Advanced technology like the mirror bore process only makes sense for Nissan if we can offer it to as many customers as possible," said Jay Boyte, director of engineering at Decherd Powertrain Plant, Nissan North America. "The end result is an innovative and efficient engine made with manufacturing technology usually not available at this volume or price point," added Boyte.
