The following question and answer session with Ford C-MAX Chief Engineer John Davis, Chief Electrified Powertrain Engineer Mazen Hammoud and C-MAX Brand Manager Patricia Piedrahita occurred on September 24, 2013. The questions and answers are not listed in any particular order of importance and do not necessarily follow the session.
Does the high voltage cooling fan(s) continue to run if need be after the C-Max hybrid is shut off? No it only keeps the battery happy when you’re driving ^MH
I’ve used android app “torque” to see instant NUMERICAL MPG, which c-max doesn’t have, please put that in next firmware update please. Great suggestion! We will take it back to our gauge engineering team.
Can I upgrade my hybrid battery to an Energi battery? Unfortunately it would take more than just the battery. Best just to buy a C-Max Energi.
I’m not experience with an electric car & haven’t driven one. What’s the estimated monthly savings of this vehicle over gas? When in EV mode, cost is about 1/2 that of gas. If you use Value Charging it’s about a quarter. ^PP
Break-in took a long time on the C-max. Close to 5000 miles for my car. Are there efforts underway to shorten this time? To maximize fuel economy, we minimize the engine run time so the longer break-in time is inherent to great fuel economy ^MH
Does it make sense to use to use ECO cruise and grade assist together to improve mpg? It’s always a good idea to use ECO cruise whenever you can and you only use grade assist when you’re driving on grade. ^JD
Is the final drive ratio the same in Hybrid & Energi? No the final drive ratios are different. Hybrid is 2.57:1 and Energi is 2.91:1. ^JD
Are you surprised by the CMax community’s mixed response to the recent FE upgrade? Most people will experience an improvement but it will vary; it addresses high speed, climate control, short trips …to know the magnitude of the fuel economy improvement, it’s best to let it stabilize over 30 days.
In a commute of say 30 miles on the Energi, with 50% highway, should I switch EV off on highway and turn it back on in city? Yes – I would drive in the hybrid EV later mode on the highway and switch to EV now in the city. ^MH
Does braking harder generate more current? No – actually braking softer & smoother allows you to recapture more of the available energy. Plan your stops! ^MH
What is the anticipated overall battery life? The battery is designed to last for the life of the vehicle. ^MH
What’s your favorite feature on the C-Max? We just polled the room. ^PP and ^MH love the brake coach feature. ^PP’s even gotten 100% score! ^JD loves the one-handed fold-flat rear seat. All agree the car’s super fun to drive.
What is the proper use of the grade assist button on the C-max shifter and how does it affect fuel economy? With proper use of grade assist button, it allows you to maintain speed downhill & regenerate without driving the brake ^MH
Are you getting closer to making hybrids more comparable in price to a gas-fueled vehicle? C-MAX Hybrid is the lowest priced hybrid utility in the market at $25,995. ^PP With newest generation EVs, we’ve reduced development costs by 25% and continue to work on this everyday. ^PP
What is the battery technology that Ford uses for its electric vehicles? We chose lithium ion. It packs more power in less space.
The clock in my CMAX Microsoft Sync dashboard is always wrong never in “Sync.” Any plans to fix? I had the same problem and the MFT update totally fixed it. It’s available at the dealer now. ^MH I had the upgrade too, but SYNC clock still doesn’t work and the voice command is useless. Any way we might get iOS in the Car?
Can you explain, in layman’s terms, the main differences between the Hybrid SEL & the Energi? The features are largely the same, but Energi is a Plug-In hybrid that gives you up to 21 miles of pure EV.
My family lives 2000 miles away how many times would I need to recharge on a trip home? C-MAX Energi plug-in hybrid lets you drive like an EV and for long trips can go 620 miles on 1 tank of gas and 1 charge. ^PP
