Gfoxsteve,
You can find EPA rated range numbers on fueleconomy.gov website.
HERE is a link that shows all Tesla models. Ignore the numbers for 90 kWh versions. These haven't been updated yet and they show the same numbers as the 85 kWh versions. Because some regulations, Tesla can't sell the 90 versions without EPA numbers, so they use the old numbers until the tests are complete.
Outside North America Tesla doesn't use EPA rated range. Therefore the UK version of Tesla website doesn't show EPA numbers. When you have your car, the car will not show EPA numbers. Instead it will show typical range and NEDC rated range, whichever you prefer. Most people prefer typical range because it is much more realistic. For example, these are the range numbers for S85:
248 miles typical range
265 miles EPA rated range
310 miles NEDC rated range
The sales person is wrong. The 70D and S85 do not have about the same range. Your idea to look at EPA rated range to compare 70D to S85 is an excellent idea. Like Tom said the numbers are 240 EPA for 70D and 265 EPA for S85. Tom said real world range is about 8
5% of that at 70mph. I agree. Based on lifetime average energy consumption data from a survey, real world range is 83% of EPA rated range on average. That means 199 miles realistic range for 70D and
220 miles for S85. Another difference is supercharge times. Here is a video:
Two important details you need to consider are degradation and speed. In terms of degradation, what you need to know is, battery capacity will drop to 95% at 37,000 miles. Then it will stay at 95%. That means your realistic range in 70D will drop from 199 to 189 miles and in S85 from 220 to 209 miles.
probably my bigger challenges are visits to customers around 120 miles away and don't have a supercharger enroute so doing there and back in a day could be full of range anxiety.
I don't think 240 miles will be possible without charging even in 90D when driving at motorway speeds (I assume 80 mph in the UK). 90D will have 286 EPA when tests are complete according to my calculation. Realistic range will be 237 miles at 70 mph. You would have to slow down to 65 mph. As you might know speed is the most important factor that affects range. In your situation 70D or S85 are not the best options. It would be better to consider 90D.
| EPA range | Realistic range at
70 mph (83%) | Realistic range at 70 mph after
degradation settles at 37,000 mi |
70D | 240 mi | 199 mi | 189 mi |
85 | 265 mi | 220 mi | 209 mi |
85D | 270 mi | 224 mi | 213 mi |
90D | 286 mi* | 237 mi | 226 mi |
