From left to right, the first is the Fluence Z.E. - a four door family car with 100 mile range.
The second is the Twizy Z.E., which is basically a covered scooter with a top speed of 47 mph.
Third and fourth are the the Kangoo Z.E. and Zoe Z.E. Both have 70 kW motors, and around 100 mile ranges.
Unfortunately I don't seen any information on price. Renault expects to start releasing these vehicles in 2011. I think the Fluence looks pretty cool.
