OK, so I got the motor bit wrong.
Apparently, the Leaf it is a permanent magnet, whereas in the Renault ZE cars ('Zero Emission') they currently use an externally excited synchronous motor. I thought the Leaf had the same. The motor is currently made by Continental, but due to be made by Renault themselves in the future (at lower cost... hmmm!).
The battery tech isn't that clear either, but I believe they are the same cell technology. The only complication being that I suspect that both Nissan and Renault have had a number of different suppliers over the course of the 'wind up' to 'full' production, so it is not simply that they have the same as each other, they may not even have the same between themselves!!
Dave/Doug - in your data logging, do you monitor the distances travelled? Obviously, for pure EV range becomes all-important. I suppose in a way my 'average' will be likewise high, but simply that I will have two cars to do it, instead of one. I guess that adds up to the same number of engines as the Volt, though!!
I am currently planning on keeping my GM Vectra going for the 18 month of the initial lease I have on this Fluence, for whatever reason I may have to hand it back at the end of the term. If I use it once a fortnight to keep all the bits in working order than rusting over, that'd mean I'd use it for 10% of the shared mileage, Fluence/Vectra. As the Vectra does 60mpg, that's make the combined pair 600mpg! Any >100 miles trips would, obviously, necessitate wheeling out the Vectra for the job.
I think of having a 'collection' of cars (we'll now have 4 cars!!
) as having a tool box. In this case, I have two tools to perform the job I need of them, whereas you guys have one tool that can do all the jobs you need. There are pros and cons to both scenarios.
