Nascar Fueling Type

The fuel injection system will bring increased technology and efficiency to the Cup Series cars while at the same time complementing the car's high performance."This move gives us an additional opportunity to incorporate the best technology in our race cars that will enhance the sport in a variety of ways," said Robin Pemberton, NASCAR vice president of competition. ECUs maximize each racing team's ability to get the most performance and best fuel economy under all race conditions. With this announcement, plans call for every Cup Series race team to use a control system with Freescale's advanced 32-bit Power Architecture based engine management processors at its core, beginning in 2012. These same processors power millions of today's most energy efficient engines.
