http://nickjhowe.com/tesla/modelsguide.html I though people here would be interested in this Tesla Model S buyers guide that was posted in another forum. It has some good info, particularly regarding the battery. They show that the real kilo wattage available is considerably less that advertised. From this diagram with a usage of 3.2kw/mile you'd end up with a 210 mile/390km range with the 85. Charging to 90% gives you 189miles/350km practical range. Extending this to the 60kwh battery, my guess would be 60-3(bricking protection)-5.1(zero mile protection) = 51.9kwh useful charge. This would be 162mile/300 km range in idea conditions and 145miles/270 km practical range. Then you can take off degradation after a year or 2. This could easily reduce the range to 300 km or 230km depending on the battery. I'd be interested in comments on the above.
