Programmable Plug-In Performance

One of the most interesting features of the Mitsubishi Outlander PHEV is the truck's versatility when it comes to combining performance and economy, along with four-wheel-drive grip and stability. Depending on driving conditions and remaining battery charge, the powertrain will automatically choose one of three different drive modes: EV Drive Mode (with zero emission power coming solely from the twin electric motors and battery pack), Series Hybrid Mode (the gasoline engine serves as an onboard generator when battery power is low, or when extra power is needed) and Parallel Hybrid Mode (the gasoline engine powers the wheels directly, with occasional power provided by the electric motors). The driver can also select Battery Charge Mode in which the gasoline engine serves as an onboard generator to help keep the battery pack's charge topped up.
Helping to ensure the Outlander PHEV isn't left spinning its wheels when the road is slick, the powertrain is coupled to Mitsubishi's proven S-AWC (Super All Wheel Control) four-wheel-drive system. Further technical specifics and pricing related to the U.S. model should be released during the Paris show. Presently, the most expensive Outlander sold stateside is the V-6-powered GT S-AWC version, which carries a sticker price of $29,420. It's reasonable to expect the plug-in hybrid variant will fall around that same range, given it's high-tech powertrain and standard fitment of all-wheel-drive.

I think the Series Hybrid mode that Mitsubishi Outlander PHEV has is very interesting. I think they could very efficiently run a car in Series Mode using propane to power the motor and have very respectable mileage.
