rmc523 Posted June 18 Share Posted June 18 (edited) The $45,000 EV That Could Change Everything: Latest Rivian R2 Details Unveiled - Autoblog The powertrain test lab’s highlights featured a closer look at Maximus, Rivian’s in-house next-generation drive unit, primarily serving in its upcoming R2 and R3. Improvements from the last drive unit, Enduro, include Maximus’s smaller size, lighter weight, lower cost, and simpler manufacturing, achieved by reducing its fasteners by 30%. Maximus’s inverter, converting direct current (DC) energy to alternating current (AC) energy, is now side-mounted, providing additional clearance for the lower R2. Rivian noted that the R2’s drive unit uses a continuous winding e-machine, generating higher performance and further simplifying manufacturing by reducing the number of welds. According to its manufacturer, Maximus is 40% more power-dense than its predecessor, much cheaper, and easier to build—all of which facilitate scaling, something Rivian struggled with while producing its R1T and R1S models. Rivian said the Enduro was its first drive unit to transition directly to hard tooling, meaning it went straight from digital designs and engineering to building production-ready manufacturing tools used for high-volume creation. Maximus is undergoing month-long testing in extreme high and low temperatures, along with simulated rainfall conditions.

sullynd Posted June 19 Share Posted June 19 The R2S will be in the running to replace my wife’s Maverick in a few years. 1 Quote Link to comment Share on other sites More sharing options...
