It's only been a few months since the 2023 BMW 7 Series and all-electric 2023 BMW i7 made their world debut. The former relies on internal combustion, with either a 3.0-liter turbocharged inline-six delivering 375 horsepower and 383 lb-ft of torque or a 4.4-liter twin-turbo V8 producing 523 hp and 553 lb-ft. As for the i7, it includes two electric motors combining to create 536 hp and 549 lb-ft with a 101.7-kWh battery enabling a 300-mile driving range.

BMW recently opened the configurator for the i7, which can reach over $160,000 when fully optioned. Now the i7 and its gas-powered counterpart have officially rolled off the assembly line at the BMW Group Plant Dingolfing in Bavaria, Germany. This factory also assembles the 4 Series, 5 Series, 6 Series, 8 Series, the all-electric iX, and bodies for Rolls-Royce.

"Our new BMW 7 Series is the first luxury sedan in the world to offer customers a choice between three types of drive. Whether fully electric, combustion-powered or, soon, plug-in hybrid, we have the flexible production structures and outstanding integration skills we need to manufacture such a diverse range of drives efficiently," said Milan Nedeljkovic, BMW AG Board Member for Production.

BMW hasn't mentioned many details about the 750e PHEV model other than it will have 483 hp, bridging the gap between the 740i and 760i. Though their drivetrains are vastly different, the 7 Series and i7 share a platform and even similar styling. This is unique from Mercedes-Benz, which separated the S-Class and EQS into two distinct models.

BMW invested more than €300 million (around $312 million) to ready the Dingolfing for 7 Series and i7 production. "We are 100 percent flexible and able to switch between drive variants for the BMW 7 Series," said Plant Director Christoph Schroder. "This means we can manufacture completely in line with demand for the various drives and use our plant capacity as fully as possible."

By the end of this year, around 50 percent of Dingolfing's production will incorporate some form of electrification. Next year, BMW will announce an all-electric 5 Series variant called the i5, which will be produced alongside the i7.
