2018 Chrysler Pacifica Hybrid Long-Term Update | Keeping things fresh

We're big fans of our long-term 2018 Chrysler Pacifica Hybrid. In the few months we've had it, we've racked up quite a few miles. We have some road-trip stories coming later on (including a 2,500-mile round trip to New England), but I wanted to highlight a small but interesting feature on our Ocean Blue people mover, the "Fuel and Oil Refresh Mode". From the owner's manual: Since it is possible to operate this vehicle for extended periods of time without running the gas engine, the fuel within the vehicle's fuel tank can become stale. To prevent engine and/or fuel system damage due to stale fuel, as well as, maintaining internal engine lubrication, this vehicle is equipped with a "Fuel and Oil Refresh Mode". The vehicle will automatically enter into the Fuel and Oil Refresh Mode to minimize potential for stale fuel, and to ensure lubrication of internal engine components. When operating in this mode, the gas engine will run to provide vehicle propulsion (electric only operation is inhibited). A message will be displayed in the instrument cluster whenever Fuel and Oil Refresh Mode is active. The vehicle will automatically exit the Fuel and Oil Refresh Mode when conditions have been satisfied. If the vehicle enters Fuel and Oil Refresh Mode, due to fuel which has been in the fuel tank for a long period of time (becoming stale fuel), the engine will run whenever the vehicle is operational (no electric only operation) until the low fuel level warning is activated. It is possible to exit the Fuel and Oil Refresh Mode sooner by adding new fuel to the vehicle's fuel tank. Basically, the engine will automatically cycle on to help burn fuel and lubricate the engine if the Pacifica has been running on pure electricity for an extended period of time. This may sound wasteful, but fuel does go stale and it's not good for the Pacifica's V6 to go without circulating oil every once in a while. A message pops up on the instrument cluster and the engine runs until the computer decides its cycled enough. In our experience, it's not run for more than a few minutes at a time. Since most of us live within 15 or so miles of the office, we can usually make it home and back without expending the Pacifica's 33-mile electric range, even if we make a trip to the store or go out for dinner. The refresh mode has kicked on a few times already, and we expect it to kick on quite a few more times before our loan is up. Related Video:

8 automakers, 15 utilities collaborate on open smart-charging for EVs

We're going to lead with General Motors here. GM is one of eight automakers working with 15 utilities and the Electric Power Research Institute (EPRI) at developing a "smart" plug-in vehicle charging system. Why did we start with GM? Because it's the first automaker whose press release we read that mentioned the other seven automakers. Points for sharing. For the record, the collaboration also includes BMW, Toyota, Mercedes-Benz, Honda, Chrysler, Mitsubishi and Ford. The utilities include DTE Energy, Duke Energy, Southern California Edison and Pacific Gas & Electric. The idea is to develop a so-called "demand charging" system in which an integrated system lets the plug-ins and utilities communicate with each other so that vehicle charging is cut back at peak hours, when energy is most expensive, and ramped up when the rates drop. Such entities say there's a sense of urgency to develop such a system because the number of plug-in vehicles on US roads totals more than 225,000 today and is climbing steadily. There's a lot of technology involved, obviously, but the goal is to have an open platform that's compatible with virtually any automaker's plug-in vehicle. No timeframe was disclosed for when such a system could go live but you can find a press release from EPRI below. EPRI, Utilities, Auto Manufacturers to Create an Open Grid Integration Platform for Plug-in Electric Vehicles PALO ALTO, Calif. (July 29, 2014) – The Electric Power Research Institute, 8 automakers and 15 utilities are working to develop and demonstrate an open platform that would integrate plug-in electric vehicles (PEV) with smart grid technologies enabling utilities to support PEV charging regardless of location. The platform will allow manufacturers to offer a customer-friendly interface through which PEV drivers can more easily participate in utility PEV programs, such as rates for off-peak or nighttime charging. The portal for the system would be a utility's communications system and an electric vehicle's telematics system. As the electric grid evolves with smarter functionality, electric vehicles can serve as a distributed energy resource to support grid reliability, stability and efficiency. With more than 225,000 plug-in vehicles on U.S. roads -- and their numbers growing -- they are likely to play a significant role in electricity demand side management.

An early gas-electric hybrid was developed by...Exxon?

We're not sure which aspect of Exxon's 1970s-era efforts to develop advanced and electrified powertrains is the most ironic. There's Exxon, that of the Valdez oil spill infamy, being on the leading edge of hybrids and electric vehicles. There's a boat-like Chrysler Cordova getting 27 miles per gallon. And there's the central role a Volkswagen diesel engine plays in that hybrid development. It's all outlined in an article (linked above) by Inside Climate News, and it's an amusing read. Flush with cash and fearing what it thought was peak oil production in the 1970s, Exxon funded a host of new ventures divisions geared to find alternatives to gas-powered powertrains. In the early 1970s, Exxon lured chemist M. Stanley Whittingham to develop what would become a prototype of a lithium-ion rechargeable battery. Then, in the late 1970s, Exxon pioneered the concept of using an alternating-current (AC) motor as part of a gas-electric hybrid vehicle. The company retrofitted a Chrysler Cordova (yes, that's the model Ricardo Montalban used to hawk) with a powertrain that combined 10 Sears Die-Hard car batteries, an alternating current synthesizer (ACS), a 100-horsepower AC motor, and, yes, a four-cylinder 50-horsepower Volkswagen diesel engine. The result was a rather large two-door sedan that got an impressive 27 mpg. And while US automakers didn't see the potential in the early concept, in 1980 Exxon and Toyota began collaborating on a project that would involve retrofitting a Toyota Cressida with a hybrid engine. That car was completed in 1981, and may have been one of the seeds that eventually helped sprout the concept of the Toyota Prius. Soon after rebuilding the Cressida, Exxon would get out of the advanced-powertrain-development business, as oil prices began to fall in the early 1980s, spurring cost-cutting measures. Cry no tears for the Exxon, though, as what's now known as ExxonMobil is the largest US oil company.
