BMW dishes on its NKL platform tech specs

BMW utilized the title “Neue Klasse” to a spread of vehicles from 1962 to 1977, beginning with the BMW 1500 that broke open a sport sedan section and commenced to determine BMW as that section’s chief. The Munich automaker resurrected the time period for what it hopes shall be one other revolution, this time christening its new EV-focused platform the Neue Klasse (NKL). The model has opened up in regards to the NKL’s technical elements over the previous few weeks, Automobile journal offering a abstract of what Chief Technical Officer Frank Weber needed to say. Beginning with the battery, BMW’s tied up with cell makers CATL, EVE, and Northvolt on round cells that shall be 1.8 inches in diameter and both 3.7 inches excessive to be used in vehicles or 4.7 inches excessive to be used in crossovers. That makes them the identical diameter however taller than the three.1-inch Tesla 4680 cells.

Completely different cell chemistries have been developed relying on the use case, prioritizing energy for M vehicles, low value for entry stage fashions, lengthy vary, or low degradation. In best configurations, the brand new cells are as much as 20% extra vitality dense than BMW’s present packs and improve packaging effectivity by 30%, return as much as 30% extra vary and 30% sooner charging. On prime of that, they’re stated to be 20% lighter, value roughly 50% much less to supply, and emit an estimated 60% much less CO2 emissions throughout manufacturing. Weber stated house owners will see 30 miles of vary added per minute at peak fast-charging charges, as much as 375 miles. The corporate advised Autocar beforehand that EV vary will max at 1,000 kilometers, or 621 miles.

Batteries will are available capacities starting from 75 kWh to 150 kWh, juicing one-, two-, and four-motor powertrains starting from outputs of 268 horsepower to 1,341 hp. Automobile stated the M division is testing an electrical prototype now, we’ll guess it is pushing the four-figure mark.

As for longevity, worst case is predicted to be at the least 80% capability and efficiency after ten years of use. Engineers have developed the system with numerous sorts of recycling in thoughts, together with a “rethink of how recycled elements can be utilized in new fashions, and the way recyclable these vehicles could be on the finish of their life cycle.” The goal is to raised the stat that simply 9% of supplies utilized in making batteries get reused.

BMW board member Nicolas Peter stated we might get our first have a look at what the NKL desires to make attainable with a Imaginative and prescient Automobile Idea coming to the 2023 Shopper Electronics Present in January. Mum’s the phrase on styling, however we must always count on the “breakthrough efforts” to be edgy. The automaker’s head of Environment friendly Dynamics was extra forthcoming about aerodynamic targets. NKL refinements are anticipated to yield a 25% acquire in aerodynamic effectivity, on prime of recent low-rolling-resistance tires that shall be 7% extra environment friendly. An Autobahn mode when touring above 70 miles per hour cuts drag much more. 

Roadgoing variations of the NKL are due in 2025 with the debut of the brand new i3, the electrical 3 Sequence, and the next-gen iX3. That very same 12 months, BMW plans to indicate a prototype solid-state battery, which can someday ship one other tech leap.
