There are a lot of unknowns regarding electric vehicles — and specifically, the nuances of financing them.
Aditya said EVs are coming and nothing can change that.
"But the question now becomes, how is the market going to change?" he said.
One of his concerns is mass-market EVs ushering in a new era of shared use and what that means for vehicle ownership and auto lending.
"Is it going to continue to be the same thing and a linear progression?" Aditya said. "Only instead of owning an internal combustion engine, you now own an electric car? Or is the landscape going to change as far as vehicle ownership is concerned?
"I think that's the critical thing which we are watching."
The three other panelists professed less concern about financing EVs or about shared ownership.
"I think the indirect lending model is going to continue, and I'm not concerned with figuring out depreciation curves and residual values, so I don't see much impact on the financing side," Ally's Timmerman said.
Harris said there's "a lot of discussion about batteries and how that's going to residualize over the years" at Ford Credit.
"We're not afraid of it, and we're really excited about it," he said. "We see electrification as the future. So we're all-in."
GM Financial's Berce said his company also is "all-in" on EVs. He said he expects EV share to increase in the U.S. market to as much as 10 percent by 2025, from almost 3 percent in December.
"We're prepared for it. We're spending a lot of time at GM Financial in terms of the products we're going to have in an electrification environment," he said. "What do we bundle into the loan or lease? All the way from charging, to battery replacement, etc.
"So it's something we spend a lot of time on."
