At the same time as the premiere of the i4, BMW is revealing the final secrets of its maxi SUV iX, whose basic empty weight fluctuates between 2440 and 2585 kg. As a result, the boulevard SUV, which is typically BMW with dynamic demands, is heavier than some small trucks. For the sake of fairness, however, it should not be left unmentioned that an Audi e-tron S, which is hardly better in terms of driving performance, is 155 kg heavier than the provisional most powerful iX xDrive50.
Plenty in there
In fact, BMW used an aluminum spaceframe body and carbon fiber-reinforced plastic in the roof, side and rear areas to minimize weight, although the term lightweight construction is prohibited in this context. The BMW iX debuts in two versions. As the iX xDrive40 it has 240 kW of power, a gross battery capacity of 76.6 kWh (net: 71.0 kWh) and a WLTP range of 372 to 425 km. The iX xDrive50 offers 385 kW of power, a gross battery capacity of 111.5 kWh (net: 105.2 kWh and a WLTP range of 549 to 630 km.
The relatively low WLTP power consumption of 19.4 to 22.5 kWh / 100 km (xDrive40) and 19.8 to 23 kWh (xDrive50, both factory specifications) is also due to the astonishingly low aerodynamic drag of the iX. With a cW-Value of 0.25, the massive iX is far less indigestible for the wind than for some observers. Even the comparatively filigree BMW i4 can beat the wind with a cW-Value of 0.24 barely slide through more smoothly.
High effort for the driving dynamics
With wheel slip limitation close to the actuator, electric x-drive all-wheel drive with an electric motor on each of the front and rear axles, and optional integral active steering with steering rear wheels, BMW had to dig deep into its bag of tricks to meet the brand’s traditional claim to above-average agility with this too Realize weight. Since the first X5 (E53) from 1999, BMW has been suggesting the creation of particularly dynamic SUVs with the phrase “Sports Activity Vehicle”.
Two classes in charging technology
The charging technology dispenses with an 800-volt electrical system. In contrast to the much cheaper i4, which can basically handle up to 200 kW charging power (DC), this charging power is only possible here with the more powerful xDrive50. The entry-level model xDrive40 can only be loaded with a maximum of 150 kW. The two iX can be charged from 10 to 80 percent in 31 (xDrive40) or 35 minutes.
According to BMW, a range of over 95 km (xDrive40) or up to 150 km can be recharged in 10 minutes up to a remaining storage capacity of the battery of 10 percent. The charging time from zero to 100 percent at the home wallbox with 11 kW alternating current is eight or eleven hours.
Latest iDrive technology
The large, curved “Curved Display” with the latest i-Drive controls, BMW Operating System 8 and the controversial expansion of touchscreen controls is identical to the system presented in the i4. The in many ways outstanding appearance of the iX in the portfolio, BMW tries to underline the interior with particularly expensive-looking materials, such as crystal glass on the i-rotary push button.
Final assembly in Dingolfing
The iX will be the first X model to be fully assembled in Dingolfing and BMW emphasizes that it will pay attention to sustainability in production. Prices start at 77,300 euros for the xDrive40 and only end at 98,000 euros for the xDrive50 for the time being, an iX M60 with over 440 kW has already been announced. The two initially available versions will be delivered from November 2021.
