Rivian founder and CEO RJ Scaringe just posted a fresh image of a Maximus drive unit—a vital component teased for some time now that will be a key piece in Rivian’s goal to reduce the cost per drive unit in its R2 EV builds.
Rivian continues to show strength during uncertain times in the automotive industry, particularly regarding legacy automakers’ electrification strategies. While threats to EV adoption linger, demand for Rivian’s American-made BEVs has stayed high despite a slight dip in deliveries last quarter.
The company is still riding the success of its first two flagship models—the R1S and R1T, which are now in the second generation. Better still, fans of the brand and EV enthusiasts alike are highly anticipating the arrival of Rivian’s encore to the R1 models, the R2, which will then be followed by a smaller R3 and a rally-like R3X.
As a young automaker, Rivian has overcome hurdles to establish itself in the EV industry, finally achieving scaled production at its Normal, Illinois, facility. Part of that strategy includes consistent innovation and improvement to improve vehicle function and performance for its customers and optimize manufacturing to reduce overall cost.
An excellent example of that evolution is Rivian’s Enduro drive unit, which was implemented on dual-motor versions of the R1T and R1S. Since then, Rivian has been teasing a new drive unit called Maximus, which we thought may also make its way into R1 builds, but have since learned will debut in the upcoming R2 EVs.
Today, Rivian founder and CEO RJ Scaringe offered a close-up look at Maximus being developed within the R2 design. Check it out:
RJ teases the Maximus drive unit in the Rivian R2
According to RJ Scaringe, the image above is Rivian’s new Maximus drive unit configuration implemented in the R2. There’s not much else of the upcoming BEV to see here, but an exciting little tidbit nonetheless.
While most consumers have been attracted to the Rivian R2’s size and look, Maximus will play a key role in Normal as the American automaker works to reduce the per-unit cost of its drive units—a primary goal it has previously shared with the public.
One key improvement we already know about is Maximus’ stator windings—one of the key components of any electric motor. Previously, Rivian shared that Maximus uses a new continuous winding technique that reduces the total welds per stator and thus the total overall cost of building each one. For comparison, Rivian’s current Enduro drive unit requires 264 stator welds, while Maximus only needs 24.
Rivian has also integrated the front rotor shaft and gear into a single forged, CNC-milled component and reduced the number of required bearings. The result is a simpler, more compact drive unit that is cheaper to build and weighs less, which is excellent news for EV range and efficiency.
With Maximus development underway, Rivian appears to remain on track to officially launch the R2 next year as promised. Be sure to check back with Electrek often for the latest Rivian news about the R2 and beyond.
