2027 BMW X6 PERFORMANCE AND POWERTRAINS: FULL BREAKDOWN.
2027 BMW X6 produces up to 617 hp from a 4.4-liter BMW M TwinPower Turbo V8, with three distinct powertrains across the lineup. BMW X6 xDrive40i pairs a 375 hp inline-six with 48V mild-hybrid assist. This page covers every powertrain, how each performs across models, and which BMW X6 fits your driving priorities at Grayson BMW.
POWERTRAIN OVERVIEW: THREE POWERTRAINS, ONE PLATFORM.
2027 BMW X6 lineup is built around three distinct powertrain configurations, each tuned to a specific performance tier. All three use BMW xDrive all-wheel drive and an eight-speed automatic transmission, but the character of each is meaningfully different in output and dynamic behavior.
The xDrive40i leads with a 3.0-liter inline-six producing 375 hp and 398 lb-ft of torque, supported by 48V mild-hybrid technology. The M60i steps to a 4.4-liter V8 generating 523 hp and 553 lb-ft of torque, reaching 60 mph in 4.2 seconds. At the top sits the M Competition, using a 4.4-liter BMW M TwinPower Turbo V8 tuned to 617 hp and 553 lb-ft of torque, completing the 0-60 run in 3.7 seconds.
All three powertrains use 48V mild-hybrid technology. BMW 48V mild-hybrid system explained

HOW IT WORKS: THE TECHNOLOGY BEHIND EACH POWERTRAIN.
xDrive40i: INLINE-SIX WITH MILD-HYBRID ASSIST.
The xDrive40i uses BMW TwinPower Turbo technology on a 3.0-liter, six-cylinder engine. TwinPower combines turbocharging, High Precision Injection, and VALVETRONIC variable valve control. The result is 375 hp arriving at 5,200-6,250 rpm and 398 lb-ft of torque available from as low as 1,850 rpm.
The 48V mild-hybrid system uses a starter generator integrated into the transmission. It recovers energy during deceleration and can provide electric assistance to support the combustion engine during acceleration. BMW X6 xDrive40i is not a plug-in hybrid and does not have a rated electric-only driving range or an external charge port. EPA-estimated fuel economy is 21 city and 26 highway mpg. EPA fuel economy ratings
The eight-speed automatic transmission manages power delivery across a broad range of driving conditions. BMW xDrive distributes power between the front and rear axles according to traction and driving conditions.
M60i: V8 PERFORMANCE WITH REFINED CHARACTER.
BMW X6 M60i uses a 4.4-liter BMW M TwinPower Turbo V8 producing 523 hp at 5,500-6,000 rpm and 553 lb-ft of torque from 1,800 rpm. The 48V mild-hybrid system recovers energy during deceleration and provides electric assistance to support the combustion engine during acceleration.
BMW X6 M60i uses an eight-speed automatic transmission. Its M Sport exhaust system reinforces the V8's distinct sound character, while Integral Active Steering improves maneuverability at lower speeds and supports stability and comfort at higher speeds.
BMW X6 M60i includes Adaptive M Suspension, with Adaptive M Suspension Professional available.
M COMPETITION: THE FOCUSED PERFORMANCE VARIANT.
BMW X6 M Competition uses a 4.4-liter BMW M TwinPower Turbo V8 producing 617 hp at 6,000 rpm. Torque holds at 553 lb-ft from 1,800 to 5,800 rpm. The 0-60 time of 3.7 seconds is supported by M xDrive paired with an Active M Differential, which manages torque distribution to help maximize traction and dynamic response.
Adaptive M Suspension Professional is standard on BMW X6 M Competition. The system continuously adjusts damping according to driving conditions while also providing selectable settings that allow the driver to tailor chassis response.
ACROSS THE MODELS: WHICH POWERTRAIN LIVES WHERE.
| Model | Engine | HP | Torque | 0-60 |
|---|---|---|---|---|
| xDrive40i | 3.0L I6 BMW TwinPower Turbo + 48V | 375 hp | 398 lb-ft | 5.2 sec |
| M60i | 4.4L V8 BMW M TwinPower Turbo + 48V | 523 hp | 553 lb-ft | 4.2 sec |
| M Competition | 4.4L V8 BMW M TwinPower Turbo + 48V | 617 hp | 553 lb-ft | 3.7 sec |
All three models include BMW xDrive all-wheel drive and an eight-speed automatic transmission as standard equipment.
BMW X6 xDrive40i and BMW X6 M60i share the same exterior dimensions: 195 inches in length, 78.9 inches in width, and 66.9 inches in height. BMW X6 M Competition is marginally different at 194.8 inches in length, 79.5 inches in width, and 66.7 inches in height, reflecting its dedicated M bodywork.
Towing capacity for BMW X6 xDrive40i reaches 7,209 lbs. BMW towing specifications BMW X6 M Competition does not offer a trailer hitch option. BMW X6 M60i is available with a trailer hitch rated at up to 7,200 lbs.
Cargo capacity is consistent across all three models: 27.4 cu ft behind the second row and up to 59.6 cu ft with the second row folded.
BMW AG preliminary test results. Actual acceleration results may vary depending on specification of vehicle, road and environmental conditions, testing procedures, and driving style. These results should be used for comparison only, and verification should not be attempted on public roads. BMW urges you to obey all posted speed laws and always wear safety belts.
REAL-WORLD BENEFIT: WHAT EACH POWERTRAIN DELIVERS DAY TO DAY.
xDrive40i owners get a powertrain that produces 398 lb-ft of torque from 1,850 rpm, placing substantial torque low in the rev range for passing and merging. The 48V mild-hybrid system can provide electric assistance during acceleration and recover energy during deceleration. At 21 city and 26 highway mpg, it is the most fuel-efficient option in the BMW X6 lineup. Drivers based in Knoxville or using the vehicle for regular long-distance travel may find this powertrain the most balanced option.
M60i owners gain a V8 that delivers a perceptible change in how the vehicle responds under firm acceleration. The 553 lb-ft of torque from 1,800 rpm gives BMW X6 M60i immediate power delivery, while Integral Active Steering improves maneuverability at lower speeds and supports stability at higher speeds.
M Competition owners get a powertrain and chassis calibrated around BMW M performance. M xDrive with Active M Differential manages power distribution to support traction and dynamic response, while Adaptive M Suspension Professional continuously adjusts damping and gives the driver selectable chassis settings.
BMW X6 M Competition reaches 60 mph in 3.7 seconds despite a curb weight of 5,454 lbs, demonstrating the combined output and traction capability of the BMW M TwinPower Turbo V8, M xDrive, and Active M Differential.
HOW IT COMPARES: BMW X6 POWERTRAIN LINEUP IN CONTEXT.
2027 BMW X6 powertrain range spans from 375 hp to 617 hp across three configurations. BMW X6 xDrive40i establishes the entry point with a turbocharged inline-six and 398 lb-ft of torque, while BMW X6 M60i adds V8 output and BMW M chassis technology.
BMW X6 M Competition raises output to 617 hp and combines the BMW M TwinPower Turbo V8 with M xDrive, Active M Differential, and Adaptive M Suspension Professional.
One distinction across the lineup is the use of 48V mild-hybrid technology on all three powertrains. The system can recover energy during deceleration and provide electric assistance to support the combustion engine during acceleration.
The available Driving Assistant Professional Package adds driver-assistance technologies designed to reduce workload during compatible driving situations, including Highway Assistant with Active Lane Change, Distance Control with Steering Assistant, and Partial Automated Driving.
