“Ford Motor Co.’s hot-selling Mustang Mach-E electric SUV and other plug-in models are being rendered unprofitable by rising raw material costs.”
Mention of $25,000 cost premium for similar-size electric SUV suggest Electric RVs that would require much greater battery capacity and are driven a lot less (reducing opportunity for fuel-cost savings) face strong headwinds.
“The company also has boosted prices on the Mach-E this year, he said, without giving specifics. But the model, which Ford is recalling for a defect that could cause it to stop running, now costs $25,000 more to produce than an equivalent gas-powered Edge SUV, he said.”
