I think that it would be great to offer the Mustang with an EV drivetrain and big battery. The one issue that comes to mind first is space. Big batteries are heavy and take up a lot of space. Granted, with some creativitiy you could split the load of a bigger battery between the engine compartment and the trunk. I do not think that the Mustang has anywhere near the space under the floor to house a big battery the way that SUVs and dedicated BEVs can. You wouldn't want all of the weight up front as that would throw off the car's handling balance badly. One thing that V8 engine lovers would appreciate about an electric motor is the massive and instant torque. While that is not going to sway hard core Mustang V8 fans who will miss the thundering V8 roar, buyers who want the style of a Mustang, and the quick speed, and who don't want the econobox look, could be enticed into buying a Mustang BEV. If Ford can fit a big enough battery to give the EV Mustang 150-200 miles of range, then I think that it would be a big hit. But frankly I see Ford going first with a turbo-4 engine combined with a smaller battery as a PHEV. Ever since they came out with the Fusion PHEV in 2013, I wondered why Ford didn't instantly offer a quicker version of their PHEV drivetrain in the Mustang and Lincoln models. But as opposed to the 50 mile+ EV range of the Volt, the PHEV Fusion Energi originally offered a meager 13 miles, and now has boosted that to 25 EV miles of range in the 2019 model. Ford would leap ahead of GM and Chrysler if they came out with a full BEV Mustang, but frankly I do not see them being that brave. Especially with their new announcement cutting their model line up dropping sedans and small cars. But a bold move here would net them increased sales and EV market credibility beyond their competition. Especially if they offered a BEV Mustang around the price of the Mustang GT. I would be sorely tempted to buy one myself.
