But the OP is considering a Prime SE, so I don't understand your last sentence. My Prime has the same size gas tank as the hybrid, gets nearly the same MPG, plus has another 45-50 miles of pure electric range. Even if the traction battery is depleted at the start of a trip, I can go over 500 miles before needing to gas up.After watching people stuck on the interstate for 7 hours in the cold I'm glad I bought the Rav4 Hybrid. Mine has everything to include Softex heated seats and I get average of 40. I travel sometimes more than 200 miles a day so I didn't want to worry about charging a vehicle.
