The 7 Series is BMW's flagship car and is only available in a sedan bodystyle (including long wheelbase and limousine models).

It traditionally introduces technologies and exterior design themes before other models in BMW's lineup.

The E23 introduced many electronic features for the first time in a BMW, including an onboard computer, a service interval indicator, a "check control panel" (warning lights to indicate system faults to the driver), a dictaphone, and complex climate control systems.

It was also the first BMW to offer an anti-lock braking system (ABS), a driver's airbag, and double-link front suspension.

It was initially available with a straight-six or V12 engine, the latter being Germany's first passenger car with a V12 since World War II.

The E65/E66/E67/E68 was the first BMW to include iDrive, "flame-surfacing" exterior styling, active anti-roll bars, a 6-speed automatic transmission, an electronic smart Key (dispensing with the traditional metallic key) and night vision.

The G11/G12 is the first car lineup of the BMW Group to be based on the modular OKL platform (Oberklasse, German for luxury class).

[13] The OKL platform adopts technology first introduced in BMW i models, namely the introduction of carbon-fiber-reinforced polymer as structural chassis components.

It adopts horizontally split headlight units featured on the X7 LCI which was also launched in April 2022.

[20] The i7 xDrive60 is powered by two electric motors generating a combined output of 536 hp (400 kW; 543 PS) and 553 lb⋅ft (750 N⋅m) of torque.
