Ford has announced it will use start stop technology on every 2017 F 150 it sells with a turbocharged Eco-Boost engine. That includes the 2017 F 150 Raptor. Since the EPA fuel economy testing procedure does not include coming to a complete stop and then starting up again, the start stop technology will probably have little or no affect on official fuel economy ratings. Typically, start stop systems increase gas mileage and lower carbon emissions by 4 to 5 percent.
“We haven’t completed 2017 F-150 fuel economy certification with the EPA, and that is required before we can share final numbers,” Ford’s Jessica Enoch told Autoblog. “Auto Start Stop does save fuel in stop-and-go city driving scenarios.” As car makers struggle to meet stricter fuel economy standards, every little bit of extra mileage helps. For those concerned about living with a start stop system on their next truck, that feature is disabled whenever the driver selects towing mode or four wheel drive operation.
Specially tuned for truck customers, Auto Start-Stop shuts off the engine when the vehicle is at a stop – except when towing or in four-wheel-drive mode – to give drivers power on demand when they need it most. When the brake is released, the engine restarts quickly.
While Ram has offered stop-start on 1500 V-6 pickups since the 2013 model year, the technology is still uncommon in the truck segment. Chevrolet and GMC have yet to include it on any of their light-duty V-6 pickups, and you won’t find stop-start on Nissan or Toyota trucks, either. No V-8 pickups offer the system.
We usually dislike stop-start in non-hybrid vehicles—we found the F-150 2.7-liter EcoBoost’s to be overly aggressive in operation—and despite their obvious NVH issues, these systems also tend to shut off engines in precarious traffic situations where immediate power is needed (such as waiting to turn left at a four-way intersection). Ford, at least, automatically disables the F-150’s system when the driver selects four-wheel drive or is towing a load. We’ll have to wait and see if the 2017 truck behaves any better.
