With CAF? Regs Closing In, Ford Says 70% of Its Cars Will Have Start/Stop B

Benefits may be overstated however. 2014 Ford Fusion with the 1.5L EcoBoost - 23/36 mpgUS city/highway goes to 25/37 mpgUS city/highway with Auto Start-Stop. On Thursday, Ford announced that it will be making available Auto Start-Stop on 70 percent of its North American vehicle lineup by 2017. While Auto Start-Stop helps reduce fuel consumption, it does not provide an 8.7 percent benefit in the city and especially not a 2.8 percent benefit on the highway as the above portrays. Making Auto Start-Stop available is part of the solution but it will never provide the benefit that Ford?s Fuel Economy Certifications are indicating.
