The 2027 Porsche Panamera uses a 348-hp twin-turbocharged V6 in its base rear-wheel-drive configuration. BMW publishes preliminary fuel-economy estimates of 24 mpg city and 31 mpg highway for the 740 models, compared with published figures of 18 mpg city and 25 mpg highway for the base Panamera. This page compares their powertrains, passenger space, technology, and ownership features to help shoppers evaluate both sedans.
The 2027 BMW 7 Series and 2027 Porsche Panamera offer different approaches to a premium four-door vehicle.

BMW’s published acceleration and fuel-economy figures for the 2027 740 models are preliminary. Porsche lists a 5.0-second 0–60 mph time for the base 2027 Panamera. Cargo figures describe different luggage-area designs, so volume alone does not capture the shape or accessibility of each space. Warranty coverage is subject to the applicable manufacturer terms and exclusions.
The 2027 BMW 740 and 740 xDrive use a turbocharged 3.0-liter inline-six with 48-volt mild-hybrid technology. BMW’s current U.S. technical-data page lists 394 hp and 428 lb-ft of torque for both models. The BMW 740 sends power to the rear wheels, while the 740 xDrive adds BMW xDrive all-wheel drive.

The difference does not apply to the entire Panamera lineup: Porsche offers other models with different output figures, including the 463-hp Panamera 4 E-Hybrid and higher-output E-Hybrid configurations.
BMW’s preliminary estimates of 24 mpg city and 31 mpg highway for the 740 models can be compared with the base Panamera’s published 18-city/25-highway-mpg figures. Actual fuel consumption will depend on driving conditions, vehicle configuration, and use. The figures should not be treated as guaranteed fuel-cost savings for an individual owner.
BMW 7 Series powertrain details
The 2027 BMW 7 Series has five standard seating positions. The base Porsche Panamera has four standard seating positions, with a fifth position available through its 4+1 seating configuration. Shoppers who regularly transport five occupants should check the seating configuration of the specific Panamera they are considering.

Inside, the updated BMW 7 Series includes standard multifunction front seats with heating, ventilation, and nine massage programs. Available Executive Lounge rear seating adds an integrated leg rest and coordinated seat adjustments, with a torso recline angle of up to 43 degrees. These rear-seat features are available equipment rather than standard on every BMW 7 Series.

The Porsche Panamera offers its own driver-assistance and parking technologies. Shoppers should compare the standard and available systems on the specific Panamera model rather than assuming that equipment offered elsewhere in the lineup is fitted to the base vehicle.
