There is no way it will have
There is no way it will have more than 269hp, or even close. I'd say around 225 (remember, the new Highlander will have 240 so Toyota won't go past their flagship SUV). The new batt power will give it more torque so acceleration will be more brisk. Its not about power, but mileage. The power is the gravy, mileage comes first for Toyota.
