The new 2023 BMW 7 Series and its electric i7 sibling have started production, so BMW has released a video showing how these flagship luxury sedans are made.
The approximately 10-minute video is divided into three parts, showing the 7 Series / i7 body assembly line at the BMW plant in Dingolfing, Germany, and the finished cars rolling off the assembly line.
In the bodywork, hordes of robots dress naked bodies with doors, hoods and panels. Once painted, the bodies are sent to the assembly line, where pretty much everything else is added. The i7’s battery pack is married to the body here, along with the front and rear sub-assemblies with pre-assembled suspension and brake components.
Assembly of the BMW 7 Series and BMW i7 from 2023
Also shown is the assembly and installation process of the roof-mounted 31-inch rear window of the 2023 Series 7, as well as the installation of the rear seats, which are inserted onto a long mechanical arm and guided into place by factory workers.
The finished cars are inspected, including a short run to the dyno, and then the more unusual part of the process begins. The cars are driven through a tunnel that connects the assembly area to the waiting areas where they will wait for the shipment.
Based on an updated version of the upcoming car’s CLAR platform, the new 7 Series is launched in 740i and 760i xDrive versions, both with mild-hybrid powertrains. The base 740i rear-wheel drive gets a 3.0-liter turbo inline-6 that produces 375 hp and 383 lb-ft of torque, with a temporary boost to 398 lb-ft available from the mild-hybrid system. The all-wheel drive 760i xDrive has BMW’s new 4.4-liter twin-turbo V-8 and boasts 536 horsepower and 553 lb-ft.
This time around BMW does not offer a V-12 option, leaving the all-electric i7 to complete the lineup. In the launch i7 xDrive60 guise, it has a dual-engine all-wheel drive powertrain that produces 536 hp and 549 Nm of torque. A 101.7 kWh battery pack will allow up to 300 miles of range, BMW estimates.
The 2023 BMW 7 Series and i7 are expected to hit US dealerships this fall. Pricing starts at $ 94,295 (including targeting for the base light hybrid 740i and $ 120,295 for the i7 xDrive60. A plug-in hybrid 7-series and a more powerful M Performance version of the i7 should arrive at a later date.
