2026 Cadillac Ascendiq Interior, Exterior, Dimensions – The 2026 Cadillac Ascendiq pushes Cadillac’s EV ambitions to new heights. Sitting above the Lyriq in the brand’s electric lineup, this all-new luxury SUV rides on GM’s flexible Ultium platform, allowing it to integrate next-generation battery and software technology seamlessly. Cadillac has completely skipped a mid-cycle refresh for this nameplate — because it’s brand new — but what they’ve delivered is a vehicle that’s unmistakably futuristic, ambitious, and tuned for high-end consumers who demand luxury with zero tailpipe emissions. 2026 Cadillac Ascendiq Interior

Exterior & Interior
The 2026 Ascendiq’s exterior is all about presence. It rides on 22-inch multi-spoke wheels with aerodynamic inserts and features active grille shutters, a full-glass roof, and Cadillac’s signature vertical lighting at both ends. The taillights stretch into the D-pillars, wrapping around the sides to create a dramatic effect at night. The hood line flows seamlessly into the windshield, and the fastback silhouette adds a coupe-like elegance to this three-row SUV. Cadillac offers the Ascendiq in several bespoke finishes, including Satin Steel Frost, Galactic Blue, and a unique Pearl Matte White reserved for top trims.
Inside, Cadillac goes beyond expectations. A massive 55-inch curved LED display spans the width of the dash, combining the digital cluster, infotainment screen, and passenger interface in one sweeping unit. The second row offers captain’s chairs with massage and ventilation, while the third row has power-reclining seats — a rarity in the segment. Cadillac’s new “SkyGlow” ambient lighting system adjusts based on time of day, and genuine open-pore wood, hand-stitched leather, and crystal glass accents emphasize the brand’s commitment to craftsmanship. The cargo space is generous, with 26 cubic feet behind the third row and up to 110 cubic feet with all rows folded. A frunk provides additional sealed storage up front.
Design-wise, the Ascendiq adopts the brand’s latest EV design language, sharing some DNA with the Celestiq sedan but expressing it through a larger, three-row SUV body. Sleek body panels, flush door handles, and a tapering rear end give it a sculpted, aerodynamic look. The massive illuminated grille, a Cadillac EV signature, is flanked by vertical LED lighting that accentuates its width and makes it instantly recognizable. Compared to the Lyriq, the Ascendiq is longer, wider, and more assertive in its stance — clearly built to compete with top-tier models from BMW iX, Mercedes EQS SUV, and the Rivian R1S.
2026 Cadillac Ascendiq Specs
Engine & Performance
Powering the 2026 Ascendiq is GM’s latest-generation Ultium battery system paired with a dual-motor AWD setup. The system delivers 500 horsepower and 525 lb-ft of torque, launching the SUV from 0 to 60 mph in just under 4.9 seconds — highly impressive for a vehicle this size. The ride is quiet, controlled, and poised thanks to adaptive air suspension and continuous damping control, which adjust automatically to road conditions and driving style. Cadillac has also fine-tuned steering for a balanced feel, and rear-wheel steering is available for better low-speed maneuverability and high-speed stability.
The battery itself is a 120-kWh unit offering a targeted range of around 360 miles on a full charge. With 800-volt charging architecture, the Ascendiq can regain 100 miles of range in just 10 minutes at a DC fast charger. Level 2 charging at home takes around 10 hours for a full recharge using a 19.2 kW AC onboard charger. Drive modes include Tour, Sport, Snow/Ice, and a customizable MyMode. The One-Pedal Driving system, further refined from the Lyriq, now allows for smoother transitions between regenerative and mechanical braking, making urban driving more efficient and less stressful. 2026 Cadillac Ascendiq Interior
2026 Cadillac Ascendiq Fuel Economy
While traditional fuel economy metrics don’t apply to EVs, Cadillac estimates the Ascendiq’s energy efficiency at around 3.2 miles per kWh — competitive for its size and weight. Owners can expect around 360 miles of range with the dual-motor setup, and real-world efficiency is enhanced by its regenerative braking system and Eco Drive mode, which prioritizes minimal energy consumption. With bidirectional charging capability and V2H (Vehicle-to-Home) integration, the Ascendiq can also act as a backup power source during outages.
2026 Cadillac Ascendiq Safety Features
Cadillac has made sure the Ascendiq delivers top-tier safety and driver-assistance features. Standard across the lineup is the latest version of Super Cruise, Cadillac’s semi-autonomous hands-free driving system, now functional on more than 600,000 miles of mapped roads across North America. This updated system allows for automated lane changes, exit maneuvers, and precise overtaking without driver intervention — all while monitoring the driver’s attentiveness via an infrared camera.
In addition to Super Cruise, the Ascendiq includes forward collision alert, automatic emergency braking with pedestrian and cyclist detection, reverse auto braking, blind zone steering assist, and intersection assist as standard. The Advanced Vision System provides a 360-degree top-down view with real-time AI object recognition, enhancing parking and low-speed maneuvering. Interior safety is just as advanced, with a 10-airbag system, a reinforced EV-specific frame, and GM’s new post-collision response software, which automatically unlocks doors, contacts emergency services, and powers down high-voltage systems in the event of a crash.
