No technical details I am afraid - anything but! Anyway, FWIW here is the page dealing with e:HEV. From what I can make out it claims to be the first HEV drive of its kind available in a small car.
No, Toyota Yaris is already avaiable with a E-CVT hybrid system. Jazz is the first small car
for Honda with a full hybrid E-CVT powertrain.
In the diagrams orange is mechanical energy and blue is electrical energy. The box at the top is the petrol engine and the box in the middle is the electric motors. There are three modes. Electric only, engine generates electricity and that electricity powers motors rather like a diesel electric train and finally conventional engine drives wheels. They say that the vast majority of daily driving will be in electric mode - longer and faster journeys will need mode 2 and 3 respectively. It will also be available in 4WD for people living in Hokkaido and such places which are covered in snow for 3 months of the year. Here I think it will be available in all models except basic but it will cost quite a lot extra. And that's what puts me off - I only do about 4,500 miles a year tops so I don't believe it is worth it. I haven't actually done the calculations though.
Jazz has always been avaiable in 4WD for japanese domestic market, such as Toyota Yaris and many other models. Most of them are not exported, in Europe we had only Subaru Justy, Suzuki Swift and Suzuki Wagon R+ offered also in 4WD. Present Jazz, called Fit in JDM, is sold with 1.3, 1.5, 1.5Hybrid I-DCD and each engine can have 4WD, both with manual or CVT gearbox (except the Hybrid sold only with the dual clutch gearbox).
Easily the Fit 4WD will have a similar scheme to the CR-V.
