2026 Cadillac ESCALADE IQL

The 2026 Cadillac Escalade IQL is a longer version of the standard Escalade IQ, which is already an imposing vehicle at nearly 19 feet long. The IQL adds 4.2 inches to that but interestingly keeps the same wheelbase length. Just like the standard Escalade IQ, the IQL is an all-electric full-size luxury SUV with three rows of seating and a screen-heavy interior. Touchscreens span nearly the entire dashboard, and you'll also find a screen in the second-row center console and dual screens on the front seatbacks with the Executive Rear Seat package. Also like the regular-length IQ, the IQL is powered by a dual-motor all-wheel-drive electric drivetrain that makes 680 horsepower in normal mode or an astounding 750 hp when the temporary Max Velocity mode is selected. Range is estimated by Cadillac at a generous 460 miles, and we saw a whopping 532 miles during our EV Range Test.

As a lengthened full-size all-electric SUV, the Escalade IQL currently has no direct competitors. The competitive set it shares with its shorter sibling, though, includes the Mercedes-Benz EQS SUV, Volvo EX90 and Rivian R1S. The Benz, though smaller, rivals the Escalade IQL's level of luxury and offers respectable range, with an EQS SUV 450+ model going 407 miles in our real-world Edmunds EV Range Test. The EX90 has less range, at 310 miles as tested, but brings an element of style and a surprising amount of driving fun to the table. The Rivian might be the most off-road-oriented and has the second-highest max range estimate in the class. However in our testing, an R1S fell short of its 410-mile estimate by 24 miles. The Tesla Model X could also be worth considering since it offers an available third row and up to 329 miles of range, but Tesla's first SUV is showing its age.

The Escalade IQL increased dimensions give it a more spacious cabin. The third row is the biggest beneficiary of the stretched body, as it gains 4.4 inches of legroom over the standard IQ and an inch of additional headroom. Because the wheelbase length is unchanged, however, getting to the third row will be just as challenging. Rear cargo volume with all seats in place increases by just 0.6 cubic feet, but overall space with second and third rows folded grows by 6 cubic feet. Parking in the city will be more difficult with the IQL's larger footprint, but is made easier thanks to standard four-wheel steering and a semi-automated parking feature.
