The system is configured from a next-generation drive battery which greatly improves energy density of previous batteries and the front and rear compact high-output motors.

Together with the reduction in weight and higher efficiency of the new EV system, a non-compromising reduction in the weight of the body has given the Mitsubishi eX Concept a cruising range of 400 km.

This drivetrain delivers the kind of torquey acceleration that can only be enjoyed in an EV as it delivers 70 kW to both front and rear wheels for a total output of 140 kW of power.

The Twin Motor 4WD drivetrain incorporates the Super All-Wheel Control (S-AWC) integrated vehicle dynamics control system which uses braking to control the front wheels and a transfer mechanism Active Yaw Control (AYC) that varies torque split between the rear wheels.

With the AYC controlling rear wheel drive split, the Mitsubishi eX Concept delivers handling which accurately reflects driver inputs.

The driver can select between three different drive modes to extract the full performance of the S-AWC system.

AUTO mode uses sensors and cameras which monitor and feedback road surface conditions to the S-AWC control unit so that it automatically selects the optimum drive mode for the surface conditions encountered along the route.

GRAVEL delivers optimum traction and drive on unpaved roads and in heavy rain while SNOW delivers optimum handling on snow-covered or other slippery surfaces.

The Mitsubishi eX Concept can be connected to a Vehicle to Home (V2H) device that allows the energy stored in the drive battery to supply enough electricity battery to power domestic appliances in an average household for four days.

A 1500W 100V AC socket also allows the battery to power appliances.

MMC's advanced connected car technology integrates vehicles with information networks. By utilising these networks, Mitsubishi Connect offers an even wider variety of services and brings a greater richness to your time in the car.

Artificial intelligence services linked to a Cloud can match information stored from internet searches, movements at home and places you visit with your interests and tastes.

When the artificial intelligence service picks up information related to that in the Cloud while you are driving, it makes recommendations based on such information.

Linked constantly to the Cloud, Mitsubishi Connect can help avoid accidents by combining and utilising information about other vehicles and infrastructure near your car.

It also analyses the car to detect abnormalities or signs of malfunction before they occur, and encourages you to have it repaired or serviced.

Should you be involved in an accident, it automatically transmits sensor information on the damage (the seriousness of the crash, whether airbags have deployed or not, etc.) as well as the location of the crash through a vehicle emergency communication system.

With these features Mitsubishi Connect offers all-round support for more reassuring and comfortable motoring.

In addition linking your car to a smartphone makes it possible to send and receive voice messages, use social network services and even make a reservation at a restaurant.

Using your time inside the car like this makes life so much more convenient.

Further evolutions in MMC's advanced active safety technology system support safer and more comfortable driving.

Advanced active safety technology systems include Forward Collision Mitigation system (FCM) and the Ultrasonic misacceleration Mitigation System (UMS).

The scope of these camera and radar-based systems has been expanded to detect pedestrians and bicycles.

FCM automatically applies the brakes when the camera and radar detect a sudden reduction in the distance with the vehicle in front and helps to avoid a collision or reduce impact damage in the event of a collision.

FCM also warns the driver if the camera and radar spot pedestrians and bicycles ahead at night or other times of poor visibility and the system determine when there is the possibility of a collision.

If necessary it will also automatically apply the brakes to avoid an accident to minimise or avoid injury.

Ultrasonic misacceleration Mitigation System (UMS) and Brake Control use a radar to detect obstructions either in front or behind the vehicle and regulates motor power when the driver presses their foot on the accelerator by mistake.

This prevents the vehicle from going forward. It also audibly and visually encourages the driver to take care.

The Blind Spot Warning system (BSW) uses ultrasound sensors and radar to monitor the areas behind the vehicle most likely to be blind spots.

With both audible and visual alerts the system encourages the driver to take care when it detects a car behind, helping prevent them from failing to observe a vehicle at or approaching either rear corner from behind when changing lanes on an expressway, for example.

The Lane Change Assist system (LCA) works in cooperation with BSW to assist the driver when merging with traffic or when changing lanes.

Should a vehicle be detected approaching one of the rear corners of the car, LCA uses audible and visual alerts to encourage the driver to take care and automatically corrects the steering wheel angle if necessary to prevent contact with another vehicle.

When driving either forward or reversing out of a garage that faces the road, this front and rear mounted camera and radar-based system issues a warning when it detects an approaching vehicle.

As well as detecting irregularities in the road surface, this camera and radar-based system determines changes in the vehicle's operating environment, such as from bitumen to dirt to sand, and changes in road surface conditions due to the weather. This information is used in the control of the S-AWC integrated vehicle dynamics control system.

The system also shares this road surface information with other cars through a connected car link.

For example, this allows cars to adjust their driving based on information from other cars in front of them about road conditions that have suddenly worsened.

In the event of a natural disaster, the system can store and analyse data detected by a number of vehicles and inform many more cars about which roads are passable and the condition of such roads.

Employing vehicle-to-vehicle, vehicle-to-road and vehicle-to-pedestrian communications, this system helps prevent accidents by detecting objects the driver cannot readily see, and alerting the driver.

For example, pedestrians on the other side of the car, pedestrians when you are waiting to turn at an intersection or oncoming cars.

When parking in a garage or parallel-parking the car, the camera and sensor-based system monitors the amount of space available and the perimeter of the car and then automatically operates the steering wheel and brakes to complete the parking manoeuvre.

The system reduces effort and stress for drivers when parking in tight spaces.

The Driver Monitor system employs an infrared camera in the dashboard and sensors in the steering column and driver's seat to monitor eye blinking, changes in posture, heart rate and other biological signals as well as vehicle drifting and other abnormalities to determine the driver's level of alertness, encouraging them to take a rest as necessary.

Any time it detects a loss of concentration or that the driver has taken their eyes off the road ahead, the system immediately issues an alert.

The Mitsubishi eX Concept pursues a variety of automated (and semi-automated running) driving technologies which are very compatible with EVs.

For example, MMC has developed a satisfying and convenient Automated Valet Parking system taking advantage of the precision control possible with electric motor drive.

Utilising the dependable torque generated by an electric motor EVs delivers driving performance which almost instantaneously responds to situational changes found in autonomous driving on roads solely for vehicular use, or in automated obstacle avoidance systems.

Automated Driving Mode position lamps are switched on to tell other vehicles when the automated driving system has taken over operation of the car.

Smart Valet Parking refers to system where everything is done automatically by linking the parking area system and vehicle system using connected car technology.

Occupants get out of the vehicle after the driver leaves it at the Smart Valet Parking area.

When they are ready to retrieve their vehicle the driver can press an icon on their smartphone or smartwatch and the vehicle automatically drives itself back to the original Smart Valet Parking area where the driver first left it.

Smart Valet Parking systems provide EV charging bays with wireless charging which uses solar or other renewable energy sources.

EVs that need their battery charged are automatically driven to an available parking spot with a charging bay.

Departure times and other instructions can easily be changed using a smartphone or smartwatch.

Using information from vehicle-to-vehicle and vehicle-to-road communications as well as from cameras and radar mounted to the car, the automated driving system analyses the situation around the perimeter of the vehicle and autonomously varies vehicle speed or changes lane accordingly.

The system also acquires information from the Cloud on traffic conditions at the destination and assists the driver in avoiding accidents, congestion or hazards.

The major technologies employed include:
  • Cooperative Adaptive Cruise Control (CACC): When driving on highways or other roads this system uses vehicle-to-vehicle communications to share information on whether other vehicles are accelerating or decelerating to make following a vehicle ahead smoother
  • Lane Keeping Assist (LKA): Uses cameras to determine the position of lane dividing lines and keep the vehicle between them
  • Automated Lane Change: This system promotes safer driving by cooperating with LCA and BSW changing lanes when it detects changes in the road situation ahead such as congestion, lane restrictions due to road works, or an object that has fallen off a vehicle ahead.
In addition, an Automated Obstacle Avoidance System uses cameras and radar mounted to the vehicle and communications with vehicles in the vicinity, to detect any obstacles for the car to avoid.

While intricately regulating the distance to other vehicles in the vicinity, whether in congested traffic or travelling at high speed on a highway, this makes for safer driving and avoids unnecessary acceleration and braking.
