This has been a question the Slate team has been trying to answer. They claim the weight distribution being more even front-to-back (batteries offsetting motor, I presume), but I don't know whether I believe them. I was interested in a Slate, but the changes at the company lately (new CEO from McKinsey, rather than an engineer), along with decisions like RWD, and the anemic acceleration (0-60 in 8 seconds) gives me pause.
