New Prius Plug-In Hybrid Makes European Debut In Paris – Oct 01, 2016– Tokyo, Japan (Techreleased) –  Combining all the attributes of the new, full hybrid, TNGA (Toyota New Global Architecture)-platform, fourth generation Prius with an all-electric range of 50 km (31 miles), the new Prius Plug-in Hybrid makes its European debut at the 2016 Paris Motor Show.

New-Prius-Plug-in-hybrid

At the heart of the new Prius Plug-in Hybrid (Prius Prime in the U.S.) is the latest generation of Toyota’s advanced PHV technology. It offers customers two cars in one; an even more sophisticated full hybrid powertrain and a real, all-electric EV driving experience with double the range of the previous generation model.

This significant increase in EV driving range is based on technological improvements in three key areas: optimum battery development, maximising EV driving performance and increasing recharging speed to enhance convenience.

Located under the rear loadspace, a large capacity lithium-ion battery is fundamental to the new Toyota PHV’s significantly improved 50 km (31 miles) EV range. Battery volume has been increased from 87 to 145 litres, its energy capacity doubled from 4.4 to 8.8 kWh and yet, at 120 kg, it’s just 50% heavier than its predecessor.

EV power has also been increased by some 83% thanks to the development of the Toyota’s first hybrid powertrain to feature a Dual Motor Drive System. A new, highly-compact one-way clutch within the transaxle allows the hybrid system generator to act as a second electric motor. This boosts EV driving power to 68 kW for better acceleration and an even more engaging performance, whilst greatly reducing engine start up frequency.

The further minimising of engine usage whilst the Prius Plug-in Hybrid is operating in EV drive mode is assured through the enhanced efficiency of the new PHV system, which builds on the 4thgeneration full hybrid technology powering the new Prius with several sophisticated new technologies.

Far more efficient than engine heating or high power electric water heaters, the heat pump can efficiently warm the interior using heat absorbed from the outside air. Mounted to the heat pump system, the gas-injection mechanism ensures heating performance even when outside temperatures are low.

Moreover, during charging, a new battery warming system will warm the cells to an efficient working temperature in outside conditions as cold as -20 degrees C. This ensures that both battery power and efficiency are maintained at a sufficient level to minimise the impact of cold weather on EV driving range, with full power available from start off in even very cold conditions.

The full hybrid drive system’s new transaxle is combined with a new, highly efficient PCU system control unit to give the Prius Plug-in Hybrid extraordinary overall operating efficiency. It combines improved EV and HV driving performance with a targeted average fuel consumption of only 1.0 l/100km and CO2 emissions of just 22 g/km.

Advanced Technology for Greater Efficiency

Every aspect of the advanced technology aboard the new Prius Plug-in Hybrid has been designed to improve the efficiency of the vehicle’s PHV powertrain, and to promote an environmentally-conscientious lifestyle.

The successful development of technology first revealed on the Auris HSD concept in 2010, the roof of the new Toyota PHV can incorporate a large solar panel which generates electricity to charge the hybrid system battery.

When the vehicle is parked (but not plugged in to a charging socket), the solar roof charges a solar battery which, when fully charged, delivers a pumping charge to the main HV battery.

During driving, the solar charging system charges the 12 volt auxiliary battery, compensating for auxiliary load and thereby reducing the energy consumption of the main HV battery.

Solar charging can increase the EV driving range of the new Prius Plug-in Hybrid by up to maximum 5 km per day, equating to some 1,000 km (620 miles) of all-electric driving per annum.
