PERFORMANCE AND POWERTRAIN.
The BMW X5 40 xDrive starts with a turbocharged 3.0-liter inline-six paired with a 48-volt mild-hybrid starter-generator integrated into the 8-speed automatic transmission. That combination produces 394 hp and 428 lb-ft of torque, with a 0-to-60 mph run of 5.1 seconds. The mild-hybrid system contributes up to 17 hp of electric boost and up to 148 lb-ft of additional torque during acceleration.
The Cayenne uses a turbocharged 3.0-liter V6 producing 348 hp and 368 lb-ft of torque. With the optional Sport Chrono Package, 0-to-60 mph takes 5.4 seconds; without it, the figure rises to 5.7 seconds. The Sport Chrono Package is an option on the Cayenne and standard on the Cayenne S.
Both lineups offer plug-in hybrid configurations. The BMW X5 50e xDrive pairs the updated inline-six with an electric motor for 483 hp combined and an estimated 44 miles of pure electric range. The Cayenne E-Hybrid produces a combined 463 hp from its V6-plus-electric setup, with a 25.9 kWh gross battery.
The X5 lineup also adds the forthcoming iX5 60 xDrive, the first battery-electric BMW X5, built at BMW Plant Spartanburg in South Carolina. The Porsche Cayenne lineup does not include a battery-electric variant at this time.
Both vehicles use adaptive suspension as standard equipment. The X5 40 xDrive offers optional two-axle air suspension, while the Cayenne S E-Hybrid and Cayenne Turbo E-Hybrid include Porsche Active Suspension Management (PASM) as standard, with adaptive air suspension standard on the Cayenne S E-Hybrid and Cayenne Turbo E-Hybrid.

INTERIOR, SPACE, AND CARGO.
Both vehicles measure within 0.2 inches of each other in overall length, so exterior footprint is nearly identical. The differences become clearer inside.
The BMW X5 is rated for five seats, while the Cayenne uses a 4+1 seating configuration.
Both vehicles offer 27.3 cubic feet behind the rear seats. Fold the seats flat, and the X5 reaches 67.7 cubic feet. The Cayenne reaches 60.3 cubic feet. Cayenne E-Hybrid variants drop to 22.1 cubic feet behind the seats and 55.2 cubic feet maximum because the high-voltage battery occupies luggage compartment space. The X5 50e xDrive PHEV does not carry the same cargo reduction.
Inside the X5, a 17.9-inch center display sits in a free-cut design, positioned ergonomically close to the steering wheel. BMW Panoramic Vision extends display content across the full width of the windshield base. The standard two-part panoramic glass roof covers approximately 28 square feet, with an opening front section. Standard heated front seats in Veganza upholstery are included, along with soft-close doors and a 2.5-zone climate control system as standard.
The Cayenne interior includes eight-way power seats, heated front seats, soft-close doors, a heated steering wheel, two-zone automatic climate control, and ambient lighting as standard. Higher Cayenne model configurations add equipment such as carbon fiber trim and a Race-Tex headliner on the Cayenne Turbo E-Hybrid.
