Mitsubishi Motors North America, Inc. (MMNA) unveiled the Mitsubishi Concept XR-PHEV during its press conference at the 2014 Los Angeles Auto Show.
Featuring a performance-oriented yet highly efficient plug-in-hybrid electric vehicle (PHEV) drivetrain, the Mitsubishi Concept XR-PHEV crossover is said by its maker to hint at the future design direction for Mitsubishi Motors production vehicles in North America
The motive force for this concept-car creation, said Mitsubishi Motors, comes in the form of a front engine/front-wheel drive gasoline-powered 1.1-liter inline-3-cylinder turbocharged engine producing 134 horsepower (100 kilowatt) which is paired with a compact electric motor producing 161 horsepower (121 kilowatt) with a high-boost converter and a main drive lithium-ion battery pack. The battery pack has a storage capacity of 14 kilowatt-hour and is located beneath the floor of the cabin.
MMNA said this potent yet extremely efficient powertrain combination makes for exciting sports car-like acceleration while offering exemplary fuel and energy efficiency – truly the best of both worlds.
A new component development to the MiEV technology system which is included on the Concept XR-PHEV is said to be the high-boost converter. Mitsubishi explained this converter raises the MiEV system to 700 volts and helps to further improve energy output and efficiency from both the electric motor as well as the generator.
For additional power optimization with reduced exhaust emissions, the 1.1-liter turbocharged 3-cylinder engine is said to benefit from the latest iteration of Mitsubishi Innovative Valve timing Electronic Control (MIVEC) variable valve-timing.
When operating in the “EV” drive setting (which Mitsubishi said is the Concept XR-PHEV’s standard driving mode), the PHEV powertrain automatically selects from the three drive system settings – EV, Series Hybrid and Parallel Hybrid. It chooses the one best-suited for that particular driving condition, taking onto consideration the remaining battery charge level within the main-drive lithium-ion battery pack.
Additionally, explained Mitsubishi, if the driver wants to remain driving the car purely in “EV” mode, this is possible by selecting Battery Charge Mode (gas engine will operate essentially as a generator to replenish the energy supply of the main-drive lithium-ion battery pack) or in Battery Save Mode). In this mode, depending on how low the energy level of the main-drive lithium-ion battery pack is, Mitsubishi said the system will reduce electric energy expenditure on “non-vital” systems such as air conditioning and will allow EV driving for a limited distance/duration.
Aiming to be versatile for all lifestyles, the Concept XR-PHEV has been fitted with several 100-volt AC onboard electrical outlets that are capable of delivering an external power supply of up to 1500 watts of power. This allows the vehicle to supply enough electricity to power the typical household’s domestic appliances for a full day from energy stored within the main-drive lithium-ion battery pack and up to a maximum of 10 days when the engine (with a full tank of gas) is used to recharge the energy supply within the main-drive lithium-ion battery pack, stated Mitsubishi.
