There is also a power reduction between the Touring and the Grand Touring due to the smaller battery pack's current output being lower. The advertised power difference is 620 hp vs 800 hp. However, remember that, at least for the Grand Touring, the 800 hp only comes when the car is set in Sprint mode, which reduces the range. (Smooth mode is the setting that produces the longest range.) Power in the Smooth and Swift modes is 670 hp and, if this tracks the Dream Edition approach, torque is also reduced in the Smooth mode below that of the Swift mode. Thus, the Grand Touring has two power output levels and three torque output levels.
If this approach holds with the Touring, to get maximum range you're probably going to get considerably less than the 620 advertised horsepower. It'll still be plenty fast, but there will be a noticeable difference between it and the Grand Touring in terms of accelerative punch.
