BMW debuts 6th-generation EV powertrain in the all-electric iX3

Summary

The first variant will be the iX3 50 xDrive, which boasts a combined 463 hp (345 kW) and 475 lb-ft (645 Nm) from its pair of motors. The front axle uses an asynchronous motor, with an electrically excited synchronous motor at the rear axle providing most of the power. There's 40 percent more regenerative braking than BMW's current powertrains. We weren't given an exact threshold where the friction brakes take over, but it should be around 0.5–0.6 G. That means that the iX3 will regeneratively brake for the overwhelming majority of the time—just 5–10 percent of braking events should require the friction brakes, we're told. And the regen should be smoother and more precise, as well as quieter than before. There's even some regenerative braking should the ABS trigger. NACS port comes standard, with a CCS1 adapter.

Energy density is 20 percent greater than the current cells, and the pack has a usable capacity of 108 kWh. That means you can expect a range of up to 400 miles, although the official EPA rating will only arrive next year. The new pack charges a lot faster, too. It can accept up to 400 kW, should you find a charger capable of such power. If so, the 10–80 percent charge should take 21 minutes. (BMW also says it will add 230 miles in 10 minutes.) The iX3 is capable of acting as a mobile power bank (V2L) as well as powering a home or even the grid (this requires a V2H-capable wall box), and North American iX3s will sport NACS charging ports. Software-defined The Neue Klasse is a clean-sheet design, and BMW has used this as an opportunity to clear out the legacy cruft that has accumulated over the years. Instead of hundreds of discrete black boxes, each with a single electric control unit (ECU) performing a single job, the iX3 uses four high-performance computers, each in charge of a different domain.
