MIRA's H4V Plug-in Hybrid

Retro-fitted hybrid technology that delivers much more than lower CO2

Based on a Skoda Fabia donor vehicle this demonstrator has many innovative features
including a new rear twist beam to facilitate the upgrade to all-wheel drive, regenerative
braking, “Plug-in” cassette battery arrangement, gearbox oil heating for reduced frictional losses, electronic differential (e-diff) which controls the 2 inboard (geared) motors and Lithium Iron Phosphate batteries.

Project highlights

• Plug-in hybrid with removable battery cassette - allows exchange for charged units or charging away from vehicle
• Retro-fitted to existing vehicle – technology can be added to current product range
• MIRA e-differential control system, for efficient power management and improved driveability
• Regenerative braking, to capture energy otherwise lost through braking
• Nanophosphate™ high power lithium iron batteries providing improved power, safety and range
• Gearbox oil heating for reduced frictional losses
• New twist beam design incorporates rear drive shafts facilitating 4WD
• Improved aerodynamics package – reduces fuel consumption under realistic driving conditions
• CO2 rating of 104 g/Km
• 64mpg equivalent fuel economy – a 30% improvement over donor vehicle
