The 60kWhr battery pack
The 60kWhr battery pack should take somewhat less time to charge up than the 85kWhr battery pack, but not that much less because of battery chemistry.
The EPA rated range of the Model S has stood true. Many owners and independent testers are verifying the 265 mile range estimates and most of them have seen over 300-mile range predictions during in-city driving. Just check out the Tesla forums under real-world range. Obviously, if you love G-forces, your range will be much less; same with traveling at higher speeds.
