The rear suspension is definitely running the bump stops too much, but we impressed a lot of people today, I was getting times that were better than other similar cars (Mazda 3, Audi A4), and within a few seconds of much more powerful sports cars.
I ran our Lotus Elise a few times and got about 42s, other Elise/Exige, Evo, Corvette, two Mustangs were in the 40-45s range, I got 47s in the Leaf. The fastest cars had very sticky tires, I have the stock Ecotecs...
It turns in much better, has a lot more grip and stays flat in the corners. I turned off the traction control, it kept cutting the power when I was having fun, and I put about 42lbs in the front tires so they didn't roll over under stress.
Here's a run on YouTube http://www.youtube.com/watch?v=SNpYI8ybgjQ
- recorded using iPhone and GPS mount, because my GoPro battery went flat.
The event was at a Great America parking lot, Santa Clara CA. We had about 20 miles of fast freeway driving each way. After 5 runs in the morning, the battery was half gone, we recharged it at Citrix offices nearby for a few hours and it had 11 out of 12 bars at the start of the afternoon, which was good for 5 more runs and the drive home.
Battery consumption was 1.2 miles/KWh. I reset it before the morning runs. Here's how it looks.
