2026 Cadillac Motorhome just dropped a bombshell at the Tampa RV Supershow: the 2026 Cadillac Motorhome is finally here. After years of rumors and teaser shots, the American luxury giant has built a Class A motorhome that looks like a rolling Escalade and drives like a dream. We got an early walk-through, and honestly, this thing is wild.
Design
Forget boxy old RVs. The 2026 Cadillac Motorhome is 45 feet of pure Detroit swagger. The front grille is basically a giant version of the new Escalade IQ, with vertical LED lights that stretch almost to the roof. Black chrome badges, 22-inch polished wheels, and a two-tone paint job (they showed Midnight Steel over Galactic Silver) make it look more like a custom yacht than a camper. Slide-outs on both sides give you up to 650 square feet when parked – that’s bigger than most apartments in Manhattan.
Power
Under the floor sits a heavily upgraded version of GM’s 8.1L Duramax diesel paired with a 10-speed Allison transmission. Cadillac says it puts out 605 horsepower and a ridiculous 1,350 lb-ft of torque. Towing capacity? Try 20,000 pounds – you could pull your boat and your buddy’s boat without breaking a sweat. On the highway it’s smooth as silk thanks to air-ride suspension and magnetic shocks borrowed from the Escalade-V. We did a quick 0-60 run (yes, in a motorhome) and hit it in about 11 seconds. That’s insane for something this big.
Mileage
Cadillac claims 10-12 mpg on the highway when you’re cruising at 65 mph with the slides in. Push it to 75 and you’ll see around 9 mpg. That’s actually pretty solid for a 45-foot palace on wheels. The 150-gallon fuel tank means you can go almost 1,500 miles between fill-ups if you baby it. City driving with stops and starts drops to about 7-8 mpg, but who buys a motorhome to sit in traffic?
Smart Tech
This is where Cadillac flexes. You get a 55-inch curved dashboard screen running the same Ultra Cruise hands-free system coming to the 2026 Escalade. It can drive itself on mapped highways, change lanes, and even park the whole 45-foot beast with the key fob. Four corner cameras plus bird’s-eye view make backing into campsites stupid easy. Inside, there’s Starlink built in, a 5G hotspot, and wireless charging pads everywhere. The fridge, lights, awnings, even the heated floors are controlled by your phone or by yelling at the built-in Alexa.
Luxury Features
Heated and cooled leather captain’s chairs up front, real hardwood cabinets, quartz countertops, a residential fridge, washer/dryer combo, and a king bed that actually feels like a hotel mattress. The bathroom has a full-size shower with rainfall head and heated tile floors. There’s even an electric fireplace and a 75-inch TV that drops down from the ceiling. Four slide-outs create separate living zones – it legitimately feels like a high-end condo that moves.
Price
Base price starts at $789,000. Load it up with the platinum package (massaging seats, exterior entertainment center, 600-watt solar) and you’re kissing $950,000. Expensive? Absolutely. But when you park next to a $500k Prevost at the campground, the Cadillac still looks newer and flashier.
