BMW i7 M70 xDrive goes official

The most powerful all-electric BMW models: BMW M is introducing an all-electric performance model to spearhead the new BMW 7 Series range. The BMW i7 M70 xDrive (electric power consumption combined: 23.8 – 20.8 kWh/100 km in the WLTP cycle) is the most powerful model with an all-electric drive system in the overall BMW Group portfolio. Equipped with an electric motor at both the front and rear axle generating a maximum system output of 485 kW/660 hp and an M-specific chassis, the new BMW i7 M70 xDrive delivers the perfect combination of electric mobility and performance, resulting in a driving experience unique in the luxury segment. The range-topping model of the new BMW 7 Series line-up accelerates from 0 to 100 km/h (62 mph) in 3.7 seconds, making it the fastest all-electric BMW model. Top speed is electronically limited to 250 km/h (155 mph).

The new all-electric performance model from BMW M will make its global debut at the Auto Shanghai international motor show (18–27 April 2023) in China. It will be built at BMW Group Plant Dingolfing, together with all other model variants of the luxury sedan. As well as being the lead plant for luxury models, the production facility in Lower Bavaria is also home to the competence centre for electric drive system production, which manufactures both the electric motors and the high-voltage batteries for all variants of the BMW i7 on site. The worldwide launch of the BMW i7 M70 xDrive will start in the second half of 2023.

The fifth-generation BMW eDrive technology installed in the BMW i7 is being constantly developed in order to further improve both power output and efficiency. This applies not only to the powertrain and power electronics, but also to the high-voltage battery and charging technology. The BMW i7 M70 xDrive is equipped with highly integrated drive units at the front and rear axles, which bring together the electric motor, power electronics and transmission within a single, very compact housing. The two motors work according to the principle of an electrically excited synchronous motor. This type of design makes it possible to completely avoid the use of rare earth metals (required for magnetic components) in the manufacture of the rotor.

An M-specific configuration of the drive system enables the BMW i7 M70 xDrive’s rear-axle motor, in particular, to achieve unprecedented levels of power density. The drive unit has a six-phase design with a dual inverter. This forms the basis for a very substantial increase in peak output that remains on tap up to high speeds, endowing the BMW i7 M70 xDrive with the power delivery characteristic of M models. The motor’s power density of 2.41 kW/kg represents an increase of 25.5 per cent over the unit that drives the rear axle of the BMW i7 xDrive60 and means that the BMW i7 M70 xDrive is fitted with what is currently the company’s most powerful electric motor.

This new standard-setting figure can be attributed to a BMW Group-patented innovation developed under the umbrella of BMW EfficientDynamics, which uses six excitation windings in the motor’s stator instead of the customary three. The resulting “double excitation” compared with conventional units allows the electric motor to generate an extremely high output, despite its exceptionally light and compact design, and to maintain it continuously into the higher echelons of the speed range. This solution is also far superior to a drive configuration using two motors at the rear axle in terms of both power density and efficiency.

The motor powering the rear axle generates peak output of 360 kW/489 hp. Its precisely coordinated interaction with the 190 kW/258 hp motor at the front axle creates an electric all-wheel-drive set-up generating system torque of 1,015 Nm (748 lb-ft) in Sport mode and as much as 1,100 Nm (811 lb-ft) when M Launch Control or the M Sport Boost function is activated. The drive system in the BMW i7 M70 xDrive therefore offers outstanding pulling power. Capable of sprinting from 0 to 100 km/h (62 mph) in an impressive 3.7 seconds, the BMW i7 M70 xDrive is the fastest purely electrically powered BMW model. Top speed is electronically limited to 250 km/h (155 mph). The performance characteristics of the drive system are also characterised by sustained power delivery, which ensures rapid speed increases even in higher speed ranges.

Another factor alongside this optimised efficiency is the high-voltage battery’s impressive energy density. Located in the vehicle’s underbody, the battery provides 101.7 kWh of usable energy. This gives the BMW i7 M70 xDrive a range of 488 – 560 kilometres (303 – 348 miles, WLTP cycle), making it eminently suitable for everyday use. The Combined Charging Unit features exceptionally advanced charging software designed for charging the high-voltage battery faster and more efficiently. The BMW i7 M70 xDrive is capable of AC charging at up to 22 kW as standard, while DC power can be taken on board at a rate of up to 195 kW. This means the range can be extended by as much as 170 kilometres (106 miles, WLTP) in just ten minutes during a mid-journey stop at a high-power charging station.

The car’s range can be extended while on the move by activating a new drive system setting. The launch of the BMW i7 M70 xDrive marks the introduction of a MAX RANGE mode for the all-electric models in the new BMW 7 Series range. In this mode, drive power and top speed are carefully restricted and comfort functions scaled back, allowing range to be increased by some 15 to 25 per cent.

The MAX RANGE mode was mainly devised for situations where drivers are unable to recharge mid-journey as originally planned because, for example, the charging station they were heading for is out of service. Switching to the My Mode Efficient and activating the MAX RANGE setting extends the range by a comfortable margin for the journey to an alternative charging point for the high-voltage battery. To this end, the vehicle’s top speed is limited to 90 km/h (56 mph). At the same time, the climate control system for the cabin is deactivated and the rear window heating switches to a lower setting, while seat heating, seat ventilation and the steering wheel heating are all disabled too in MAX RANGE mode. A popup window appears in the control display indicating the resulting gain in range as a distance. The information display also blanks out the section of the speed gauge beyond 90 km/h (56 mph) and shows the extra range.

The MAX Range mode can be triggered using the control display’s touchscreen functionality, the Controller or voice commands to the BMW Intelligent Personal Assistant. It can also be deactivated by hard in-gear acceleration (kickdown), engaging the M Sport Boost function or switching windscreen ventilation to maximum.

Standard specification for the BMW i7 M70 xDrive includes M‑specific adaptive two-axle air suspension with electronically controlled dampers and automatic self-levelling. M-specific air springs with reduced volume and an adapted rolling contour increase the number of vibrations on the front and rear axles by six in each case and provide a noticeably direct connection to the vehicle body. M-specific hydraulics are also used to optimise damper response.

An additional shear panel between the bulkhead and spring strut towers produces a substantial increase in body rigidity at the front end of the BMW i7 M70 xDrive. Also to be found on the standard equipment list are Integral Active Steering and the Executive Drive Pro chassis package including active roll stabilisation with Active Roll Comfort. As well as helping to increase comfort, these two systems – together with the stiffer body – hone the car’s handling dynamics. This translates into an appetite for corners, which are taken with sharp and precise turn-in characteristics.

The blue M Sport brakes with M logo fitted as standard come with large brake discs for increased stopping power. Brake callipers painted in black are available as part of the optional M Performance package. This is also the first time that sport tyres have been offered as an option for a purely electrically powered BMW 7 Series model. The standard 21-inch M light-alloy wheels on the new BMW i7 M70 xDrive feature an exclusive, aerodynamically optimised design with a Jet Black solid finish and high-gloss metal inserts.

The superior performance of the BMW i7 M70 xDrive, which results from the most powerful drive system ever developed with BMW eDrive technology and from M-specific chassis technology, is authentically reflected in its confident design. Fronted by M-specific design features like the M exterior mirrors with distinctive twin-stalk design, the BMW kidney grille with M badging, bespoke inlays in the rear bumper and M logos on the front side panels, the BMW i7 M70 xDrive flies the flag for a new era of all-electric mobility in the luxury segment. At the same time, its extravagant appearance marks another milestone in the electrification of the BMW M brand.

A large selection of exterior paint shades is available for the BMW i7 M70 xDrive, including variants of striking matt-sheen Frozen paint finishes. Owners can add an extra layer of visual extravagance with BMW Individual two-tone paintwork, which can now include BMW Individual special paintwork colours. Available from the launch of the BMW i7 M70 xDrive is the combination of BMW Individual Liquid Copper metallic for the lower section of the body and Saphire Black metallic for the upper section. An exquisite, precisely drawn coach line separates the two colour zones from one another like a delicate signature.

The BMW i7 M70 xDrive is one of the brand’s first models to feature the updated version of the control/operation system BMW iDrive with QuickSelect and BMW Operating System 8.5. In order to make selecting and operating numerous functions and digital services even more intuitive and comfortable, the latest generation of BMW iDrive offers a newly designed home screen and QuickSelect functionality. This brings an improved menu structure that takes its cues from consumer electronics devices. By showing the right information in the right place, the new BMW iDrive helps to deliver a focused, assured driving experience.

The emotionally engaging performance experience on board the new BMW i7 M70 xDrive is further enhanced by M-specific content in the BMW Curved Display. In key areas, the typography and presentation of graphics reflect those in the cockpit of high-performance models from BMW M GmbH. The numbers in the speed read-out on the information display appear in a platinum/silver colour. Plus, activating the M Sport Boost function triggers a typically M visual accompaniment. The BMW iDrive with QuickSelect is underpinned by an upgraded version of BMW Operating System 8, as employed in current BMW models with the BMW Curved Display. BMW Operating System 8.5 uses the latest generation of the infotainment head unit, which takes care of graphics processing, among other things.
