[1] Introduced in April 2022,[7] 7 Series and i7 are the respective designations for BMW's internal combustion and battery electric full-size luxury flagship models.

[16] The model was spied testing in October 2021, which was the same month that BMW CEO of development Frank Weber had announced the G70 and the G60 would both optionally offer Level 3 autonomous driving.

[20] The G70 7 Series is offered with petrol, plug-in hybrid, diesel, and battery electric powertrains, with the latter being marketed as the i7.

[15] The G70 is built upon the rear-wheel drive based Cluster Architecture (CLAR) platform shared with the smaller G60 5 Series.

This platform was used on the previous model and underpins vehicle that feature a longitudinally mounted combustion engine or a fully-electric drivetrain.

[22] In North America, three trims are available for its late 2022 introduction, including the electric i7 xDrive60, and the internal combustion 740i and 760i xDrive, both equipped with 48 V mild hybrid systems.

The internal combustion variant with plug-in hybrid model is the 750e xDrive M Sport CKD, introduced in 2023.

[27] The unit features Swarovski crystals as headlamps, which are backlit by fourteen individual LEDs on each side of the vehicle.

[29] Its side profile continues in a familiar way of the front, by keeping its characteristic lines to a minimum.

A shoulder line below the glass connects from the daytime running lamps to the edge of the taillights.

The i7's drag coefficient is rated at 0.24 Cd,[30] while on ICE models it increases to 0.26 due to engine cooling.

[36] A Pure Excellence design package is available and adds chrome exterior elements and grey brake calipers.

[35] The G70 also features navigation, wireless Apple CarPlay and Android Auto, DAB+ radio, over-the-air updating, and a range of third-party apps as well as in-car gaming.

[35] Multiple BMW models from 2022 feature the "Connoisseur Lounge" package, which allows the rear-left passenger to recline their chair.

This 7 Series features perforated Veganza leather trim covering the seats, dashboard, and steering wheel.

[35] Mild hybrid models feature a 48-volt starter-generator/electric motor integrated into the transmission, which is paired with a 20 Ah lithium-ion battery to increase efficiency and power delivery.

[45] Plug-in hybrid models feature a permanent-magnet synchronous motor, paired with an 18.7 kWh lithium-ion battery.

[60] Unveiled simultaneously with its ICE counterpart,[61] the vehicle features a similar powertrain setup to the iX crossover SUV, including an excited synchronous electric motor at the rear for rear-wheel drive models while on all-wheel drive models, two motors are placed at both front and rear axles.

[64] The singular motor eDrive50, which was introduced in May 2023 as the entry-level i7, features BMW's eDrive which produces an output of 355 kW (476 hp) and 650 N⋅m (479 lbf⋅ft).

[69] The range-topping M70 xDrive model features dual eDrive motors that produce a combined output of 485 kW (650 hp) and 1,100 N⋅m (811 lbf⋅ft).

[70] Engineers of the i7 have made minimal updates to the regenerative braking system from the other full-electric iX and i4 models.

Adaptive recuperation is the standard configuration when in driving position D. The driver can experience three levels of brake regeneration settings, low, medium and high.

[74] In the US, the i7 is able to charge with the "Electrify America" DC fast charger, which may add 180 to 200 mi (290 to 320 km) of electric range in a 30-minute session.

[81] The G73 features a "Protection Core", which allows it to survive ballistic attacks or explosions, proven by extensive studies officially confirmed by German test facility Beschussamt Muenchen.

[82] The armoured inner core surrounds the passenger compartment and invisibly protects the occupants of the vehicle.
