2027 Escalade IQ gets a Tesla plug, and the adapter moves to your garage

Cadillac's biggest EV won't need an adapter at a Tesla Supercharger anymore. The 2027 Escalade IQ comes with a Tesla-style NACS port built in, and every trim now gets the fast home charger that used to come only on the pricier versions. If you're shopping for one, road trips and overnight charging both get simpler.

Today's Escalade IQ uses the older CCS1 plug, so owners who want to use a Supercharger have to buy an adapter from GM. GM says the switch covers its whole EV lineup for the next model year, across Chevrolet, Cadillac and GMC, from the small Bolt up to the Hummer EV. It's the payoff of the charging deal GM signed with Tesla (TSLA) in 2023.

The adapter now lives in your garage

Switching plugs doesn't get rid of the adapter. It just moves it. If your garage has a J1772 wall box, the plug most non-Tesla home chargers use, the new Escalade needs an adapter to use it, and the same goes for older CCS fast chargers on the road. The home one is GM's J1772 AC Adapter (part 86286534), rated for up to 19.2 kW, and it's sold separately rather than included with the car. Electrek and Chevrolet's accessories site list it at $67, but Cadillac's own accessories site shows the same part at $99, so check before you order. Superchargers aren't a sure thing either, because some older sites still serve only Teslas.

Faster home charging for a very big battery

The Escalade IQ carries a 205 kWh battery, and until now only the top trims got the faster onboard charger, the part that handles home charging. For 2026, the Premium Luxury and Premium Sport got a 19.2 kW charger while the Luxury and Sport made do with 11.5 kW. For 2027, 19.2 kW is standard on every trim. The math is easy to check: 205 kWh divided by 19.2 kW is about 10.7 hours, call it 11, against roughly 18 hours (205 divided by 11.5) on the old base charger, and real charging runs a little longer than that best case. To get that speed you need a 240 volt, 80 amp home circuit, and DC fast charging is no quicker than before.

For the next few years, GM drivers will carry different adapters depending on their car's model year: one for Superchargers on older cars, one for home chargers on newer ones. Next, watch for the 2027 price and on-sale date, which we haven't been able to confirm yet. If you're buying now, TrueCar lists cash offers of up to $4,500 on the 2026 Escalade IQ this month, depending on where you live, while GM's Supercharger adapter for the 2026 cars costs $275, according to Electrek. Would a discount that size get you to live with a dongle?
