BMW Preps to Launch First Electric SUV
BMW says it will start making its first all-electric crossover vehicle, the iX3, this summer.
The small SUV will be sole-sourced from BMW’s joint venture plant in Shenyang, China. Chairman Oliver Zipse says the car will launch on time in spite of disruptions caused by the coronavirus pandemic.

More Models to Come
The iX3 is notable for its flexible platform, which also can accommodate a hybrid or conventional piston powertrain. The chassis also reportedly will carry BMW’s i4 high-performance electric sport sedan due in 2021.
BMW aims to add a dozen EVs and 13 hybrid models by 2023.
The new iX3 will feature a 74-kW, lithium-nickel-cobalt-manganese battery and updated electric motor that delivers 286 hp and 195 lb-ft of torque to the rear wheels. The motor eliminates the need for rare earth materials, a first for BMW’s electric drives.
To cut battery costs, BMW lowered the cobalt content and is directly purchasing and supplying cobalt and lithium for its cell supplier. The unusually high energy density of the design provides an exceptionally good range-to-weight ratio compared with rival EVs, according to the company.
BMW says the powertrain, which integrates the motor, gearbox and power electronics, has a power-to-weight ratio that is 30% better than the previous system.
The iX3 can travel about 273 miles (440 km) on Europe’s WLTP test cycle. BMW attributes about 6 miles (10 km) of that distance to the vehicle’s unusual aerodynamic wheels, which comprise an aluminum structure and bonded lightweight aero inserts.
The combination, which is 15% lighter than BMW’s previous aero wheel design, lowers overall vehicle drag by 5%. The two-part construction enables the company to modify the look of the wheels with different shapes, colors and finishes.
Volkswagen AG may be ordered to recall 124,000 of its plug-in hybrid and all-electric vehicles because their high-voltage charging systems contain a carcinogenic part.
Sandy Munro and his team of engineers and costing analysts at Munro & Associates were contacted by UBS Research—an arm of the giant banking and investment firm—and asked whether it was possible to do a teardown and cost assessment of the Chevrolet Bolt EV.
