[QUOTE="OX1, post: 16785944, member: 175132"] And apparantly range SUCKS at the averege NJ rush hour highway speed of 80 MPH (at least below GSP exit 131). From a ***-E owner "Your speed will absolutely kill your range. You can have one or the other. One must bear in mind that the EPA rating of 250 miles is calculated with 50% city driving (stop and go, 35-45 MPH) and 50% highway (which the EPA uses 65 MPH for). if you’re planning on driving 100% highway, you’ll lose a bit of range. If you plan on driving at 80 MPH, you’ll lose significantly more range. I did a comparison in my own premium AWD ER and I lost about 0.2 miles/kWh for each 5MPH I added to the speed. So, if we’re going to say that EPA rated the 88kwh GT at 250 miles, they are planning 2.8 miles/kWh. You will be eliminating all the higher milage stop and go stuff on a long trip. Let’s say that only drops your efficiency to 2.6 miles/kWh. Then you drive 80 MPH instead of 65 MPH. This will probably cost you another 0.6 miles/kWh. You’re down to a flat 2 miles/kWh. If you’re charging to 80% of your 88 kWh battery then you only have 70 kWh available. Looks like you will get about 140 miles of range at those speeds." [/QUOTE]
