EPA fuel economy data for the 2026 BMW X6 M60i and BMW X5 xDrive40i
PERFORMANCE AND POWERTRAIN.
BMW X6 M60i's V8 produces 523 hp and 553 lb-ft of torque, with torque available from 1,800 rpm. That broad torque band means the vehicle responds with force at highway speeds, not just from a standing start. BMW rates the 0-60 mph run at 4.2 seconds. The 48-volt mild hybrid system adds electrical assist at low speeds, smoothing transitions without changing the fundamental character of the engine.
BMW X5 xDrive40i uses a 3.0L BMW TwinPower Turbo inline six-cylinder paired with the same 48V mild hybrid architecture. At 375 hp and 383 lb-ft, it is a genuinely strong powertrain for daily driving and longer trips, but it operates in a different performance category than BMW X6 M60i's V8. Both vehicles use an eight-speed automatic transmission and BMW xDrive all-wheel drive.
BMW X6 M60i also adds the M Sport Differential, Integral Active Steering with rear-wheel steering, and an M Sport Exhaust System as standard equipment. These hardware differences translate to sharper turn-in and reduced turning radius at parking lot speeds, which is notable for a vehicle of this size.
INTERIOR, SPACE, AND CARGO.
Both vehicles seat five. BMW X6's fastback roofline, which drops more steeply toward the rear, reduces headroom for second-row passengers compared with BMW X5's taller, more upright body, though specific rear headroom figures were not included in the verified spec data.
BMW X6 offers 27.4 cu ft of cargo space behind the second row and 59.6 cu ft of maximum cargo capacity. BMW X5 xDrive40i provides 33.9 cu ft behind the second row and 72.3 cu ft maximum. Shoppers for whom cargo volume is a primary requirement will find BMW X5 xDrive40i offers greater overall flexibility.
BMW X6 M60i's standard interior list is extensive: ventilated front seats, heated front-seat armrests, heated steering wheel, four-zone automatic climate control, a 16-speaker Harman Kardon audio system, and a Head-Up Display. BMW X5 xDrive40i includes power-adjustable and heated front seats with dual-zone climate control in its standard configuration, with options available above that.
TECHNOLOGY AND SAFETY.
Both vehicles carry BMW's forward collision warning with automatic emergency braking, blind spot intervention, lane departure steering assist, automated parking, and front, rear, and side parking sensors with automatic braking. BMW X6 M60i adds lane departure warning and forward collision mitigation as additionally listed items in the verified spec data.
On the technology side, BMW X6 M60i includes a 360-degree surround-view camera system, wireless Apple CarPlay and Android Auto, Remote Engine Start via the My BMW App, Advanced Real-Time Traffic Information, and a 16-speaker Harman Kardon audio system. BMW X5 xDrive40i includes the BMW Curved Display, a 12.3-inch digital gauge cluster paired with a 14.9-inch central infotainment screen, along with Comfort Access keyless entry and a panoramic moonroof as standard.
Both vehicles offer wireless Apple CarPlay and Android Auto connectivity. Buyers wanting the most safety and driver-assist technology from the factory will find BMW X6 M60i's standard list longer, while BMW X5 xDrive40i's Curved Display is a meaningful upgrade in infotainment presentation.
VALUE AND OWNERSHIP.
BMW X6 M60i and BMW X5 xDrive40i are both covered by the BMW New Vehicle Limited Warranty for four years or 50,000 miles. BMW Ultimate Care also includes scheduled maintenance for three years or 36,000 miles.
Fuel economy is the clearest ownership difference. BMW X5 xDrive40i's inline six-cylinder returns 23 city / 27 highway / 25 combined mpg, compared with BMW X6 M60i's 17 city / 22 highway / 19 combined mpg. Over 15,000 miles per year, that gap is meaningful for buyers who drive frequently in city conditions.
Both vehicles match at 7,200 lbs of towing capacity, making either suitable for towing a boat or trailer without one holding a clear advantage.
