BMW 740 xDrive produces 394 hp and returns 30 mpg highway, outpacing the Genesis G90 3.5T AWD's 375 hp and 26 mpg highway. The 740 xDrive also carries 19.1 cu ft of cargo versus the G90's 12 cu ft trunk. This page compares both vehicles across performance, technology, and ownership so you can find the right fit at Grayson BMW.
THE SHORT ANSWER.
BMW 740 xDrive is the stronger choice for the driver who values a connected, technology-forward cabin, superior fuel efficiency, and a larger trunk. Genesis G90 3.5T AWD appeals to buyers who prioritize a longer powertrain warranty and a more traditional luxury sedan experience. Neither is a wrong answer, but the differences below are meaningful.

PERFORMANCE AND POWERTRAIN.
BMW 740 xDrive pairs a 3.0L TwinPower Turbo inline six-cylinder engine with 48V mild-hybrid technology, producing 394 hp and 428 lb-ft of torque. The 8-speed Sport Automatic transmission includes Sport and Manual shift modes with paddle shifters. BMW AG preliminary testing puts the 0-60 mph run at 4.9 seconds. The xDrive all-wheel-drive system distributes power across all four wheels.
The fuel economy advantage is significant: the 740 xDrive achieves 24 city / 30 highway / 26 combined mpg, compared to the G90 3.5T AWD's EPA-rated 18 city / 26 highway / 21 combined mpg. Over a year of typical driving, that gap adds up.
The 2026 Genesis G90 3.5T AWD uses a 3.5L twin-turbo V6 producing 375 hp and 391 lb-ft of torque, also paired to an 8-speed automatic with paddle shifters. Genesis does offer higher-output variants with an electric supercharger that raise output to 409 hp, but those are separate trim configurations not directly compared here.
Air suspension is standard on BMW 740 xDrive, with adjustable ride height. The G90 3.5T AWD uses electronically controlled suspension, while multi-chamber air suspension is reserved for the G90's higher trim levels.

INTERIOR, SPACE, AND CARGO.
BMW 740 xDrive is longer by 4.9 inches (212.6 in versus 207.7 in), and that extra length shows up where it matters most: the trunk. At 19.1 cu ft, the 740 xDrive offers substantially more cargo space than the G90's 12 cu ft. For buyers who routinely travel with luggage, that difference is practical.
The 7 Series cabin centers on BMW Panoramic iDrive, a dashboard-spanning digital instrument panel paired with a 17.9-inch center touchscreen and a 14.6-inch front passenger touchscreen. Four-zone automatic climate control, heated and ventilated front and rear seats, a heated steering wheel, soft-close doors, and a panoramic sunroof with color-changing LED lights are all standard. Multi-color ambient interior lighting and an air suspension system with adjustable ride height further shape the in-cabin experience.
The G90 delivers genuine luxury touches as well: Nappa leather seating surfaces, a microfiber suede headliner, real wood trim, power-folding doors, and three-zone climate control are all standard. Rear seat massage and ventilation are available on higher G90 trims. The G90's interior dimensions show 42.3 inches of front leg room and 37.8 inches of rear leg room.
Both vehicles include wireless smartphone charging, proximity keyless entry, and power-closing doors. BMW 740 xDrive offers BMW Digital Key Plus, while Genesis Digital Key 2 is included on the G90.
TECHNOLOGY.
The 2027 BMW 740 xDrive presents one of the more technology-dense cabins in its segment. BMW Panoramic Vision spans the full width of the windshield. The BMW 3D Head-Up Display delivers three-dimensional information projection. A 17.9-inch center display runs BMW Operating System X, and a separate 14.6-inch BMW Passenger Screen gives the front passenger independent control. The Bowers and Wilkins premium audio system is standard. Wireless Apple CarPlay and Android Auto, navigation, Bluetooth, satellite radio, and remote engine start are all included.
The G90 runs dual 12.3-inch screens (instrument cluster and center display) alongside a head-up display. Its Bang and Olufsen 15-speaker system is standard; a 26-speaker Bang and Olufsen 3D system with Dolby Atmos is available on higher trims. Five USB-C ports, wireless Apple CarPlay and Android Auto, and Genesis Digital Key 2 are standard.
SAFETY.
On driver-assistance technology, both vehicles are well equipped at their base configurations:
BMW 740 xDrive standard safety includes forward collision warning with automatic emergency braking, adaptive cruise control, lane keeping assistance, a lane centering system, blind-spot warning with rear cross-traffic warning, an automated parking system, front and rear parking sensors, and stability and traction control.
The 2026 G90 3.5T AWD adds Safe Exit Assist, a surround-view monitor, Highway Driving Assist 2, and a blind-spot view monitor as standard features. Both vehicles include standard automated parking assistance.
Neither vehicle should be described as autonomous. These are driver-assistance systems that require the driver's attention at all times.
VALUE AND OWNERSHIP.
Warranty coverage is one of the clearest separators between these two vehicles. Genesis backs the G90 with a five-year / 60,000-mile basic warranty and a ten-year / 100,000-mile powertrain warranty. BMW 740 xDrive carries a four-year / 50,000-mile basic warranty and a four-year / 50,000-mile powertrain warranty.
For long-term ownership confidence, Genesis holds a measurable advantage on paper warranty terms.
On fuel efficiency, the 740 xDrive's 48V mild-hybrid technology contributes to a 26 combined mpg rating, five points above the G90 3.5T AWD's 21 combined. That gap is meaningful for buyers who put significant miles on a vehicle each year.
Standard content on both vehicles is generous. The 740 xDrive includes air suspension with adjustable ride height, four-zone climate control, a panoramic sunroof with LED lights, the Bowers and Wilkins audio system, and BMW ConnectedDrive as standard equipment. The G90 includes Nappa leather, three-zone climate, surround-view monitor, Highway Driving Assist 2, and the Bang and Olufsen 15-speaker system at its base trim.
WHICH ONE SHOULD YOU BUY.
CHOOSE BMW 740 xDrive IF:
- Fuel efficiency in a full-size luxury sedan matters. The 26 combined mpg outpaces the G90 3.5T AWD's 21 combined by a significant margin.
- You want a technology-forward cabin anchored by BMW Panoramic Vision, the BMW 3D Head-Up Display, and a 17.9-inch center touchscreen paired to BMW Operating System X.
- Cargo space is a priority. At 19.1 cu ft, the trunk is 7.1 cu ft larger than the G90's.
- You value a vehicle with air suspension and adjustable ride height as standard equipment.
- You're in the Knoxville area and want to see current inventory and speak with a product specialist at Grayson BMW.
CHOOSE GENESIS G90 3.5T AWD IF:
- A ten-year / 100,000-mile powertrain warranty is a deciding factor in your purchase.
- You prefer a wider selection of airbags at the standard level, including a driver knee airbag and center side airbag.
- An available 26-speaker Bang and Olufsen 3D audio system with Dolby Atmos is specifically on your list.
- You are drawn to the G90's traditional luxury sedan proportions and prefer a lower roofline.
Both vehicles are legitimate contenders in the full-size luxury sedan segment. The 740 xDrive separates itself through fuel efficiency, cargo volume, and display technology. The G90 earns consideration for its warranty terms and available audio system. The right choice depends on which of those priorities ranks highest for your situation.
