Just if you are interested, top speed at 112 mph, car has a very soft speed limiter. You don't feel the car is travelling that fast but can't call it "rock solid" at this speed. It's running at 7.9 mpg, and the battery is depleting real fast.

 

That is pretty identical to my RX300, though if you have a portable GPS you can reach 120 on a slope regardless of the fuel cutoff. I also remember about 6 to 8 mph on those runs.
