The iPhone 8 and iPhone X sport wireless charging and there are a handful of car manufacturers that already include Qi charging pads.
Basically, Apple says, most of these wireless charging pads will work though there are some outliers.
The main exception is some of the pads are not large enough for the iPhone 8 Plus so in that case, you’ll have to plug your phone into a cable to charge. There’s no workaround if the phone is too big.
Generally speaking, wireless charging pads built into cars from these makers will work.
Audi
BMW
Chrysler
Ford
Honda
Mercedes-Benz
PSA
Toyota
Volkswagen
Volvo
Things get messy with General Motors brands, though as the maker starting including wireless chargers in its 2017 model line but those pads do not Qi standards. As such, only the following models at this time support wireless charging on the iPhone 8 and iPhone X.
2018 GMC Terrain
2018 GMC Yukon
2018 GMC Sierra
2018 Chevrolet Bolt
2018 Chevrolet Tahoe
2018 Chevrolet Silverado
2018 Chevrolet Suburban
2018 Cadillac Escalade
2018 Buick Enclave
