Unveiled at 2026 Chengdu Auto Show: Cadillac XT5 PHEV with Ultium Battery and Momenta R7 World Model

At the 2026 Chengdu International Automobile Exhibition, the Cadillac XT5 PHEV made its official debut. As the brand's first plug-in hybrid mid-to-large SUV built on the Ultium platform, pricing and launch timing remain unannounced — but it will feature a 1.5T engine paired with a dual-motor PHEV system, a 35.5 kWh nickel-cobalt-manganese (NCM) battery, and Momenta's R7 world model for intelligent driving.

The exterior design carries over styling cues from the current XT5 gasoline version: the front fascia retains the iconic shield Integra grille with a mesh texture, complemented by a split LED headlight assembly. A roof-mounted LiDAR unit enhances hardware redundancy for advanced intelligent driving. Side profile features conventional door handles and multi-spoke wheels, while gloss-black window trim adds refinement. The rear employs a chrome strip connecting the T-shaped taillights horizontally, plus a rear spoiler; exhaust outlets are now fully hidden to de-emphasize powertrain type.

Dimensions measure 4888 × 1957 × 1685 (1688) mm, with a 2863 mm wheelbase — positioning it firmly in the mid-to-large SUV segment. The interior continues the curved dual-screen layout (fully digital instrument cluster + central infotainment display), paired with a three-spoke multifunction steering wheel. The center console adopts a two-tier, two-tone structure; the center console area includes a wireless charging pad, dual cupholders, and dedicated physical control knobs — emphasizing tactile feedback and scenario-aware human-machine interaction.

The powertrain combines a 1.5T engine (max output: 115 kW) with front and rear electric motors (max outputs: 160 kW and 110 kW respectively), mated to a 35.5 kWh Ultium 5C NCM battery. WLTC all-electric range is rated at 155 km, with a WLTC combined fuel consumption of 6.05 L/100 km. Underpinning the vehicle is a full-terrain Electric Hummingbird chassis, supporting multi-mode adaptive damping and ride-height adjustment.

On the intelligent driving front, the Cadillac XT5 PHEV ranks among the first production vehicles globally to adopt Momenta's R7 world model. Unlike conventional perception-and-recognition systems, R7 interprets physical object properties, motion causality, and interaction possibilities — enabling more physically grounded trajectory prediction and strategic planning in complex scenarios such as rush-hour commuting, narrow-road passing, path-tracing reverse maneuvers, and automated parking.
