Rivian’s New Enduro Drive Unit Boosts EPA Vary

A brand new EPA certification utility that appeared on Rivian Boards reveals what may be the efficiency and vary outcomes of Rivian’s new in-house constructed dual-motor Enduro drive unit. Up to now, the corporate relied on exterior suppliers for its electrical motors, however now with its personal drivetrain, it’s anticipated to train extra management over prices and manufacturing.

The in-house powertrain entered manufacturing final month for the R1S electrical SUV and R1T electrical truck. The new findings point out a small bump in vary and efficiency in comparison with Rivian’s earlier estimates.

Rivian estimated the vary for its R1S with the all-terrain improve and the Massive, 135-kilowatt-hour battery pack, to be 300 miles. The EPA estimate is barely extra optimistic at 305.79 miles, or roughly 2 % higher.

The model projected the 2023 R1S with the 22-inch wheels to have a spread of 320 miles, whereas the EPA determine is about 6 % extra at 340 miles. The identical might be mentioned in regards to the longest-range R1S, which will get 21-inch wheels. Its preliminary vary estimate was 340 miles, whereas the EPA determine is about 3.5 % extra at 352.06 miles.

In comparison with the quad-motor model, the brand new dual-motor R1S with 22-inch wheels has about 11 % extra vary, whereas the one with 21-inch wheels has roughly 9 % extra vary.

How does EPA calculate these figures? In response to one report, EPA multiplies its preliminary freeway and metropolis vary outcomes by 0.7 to account for various driving kinds and circumstances. Therefore, the mixed vary figures you see within the photographs connected to this piece are adjusted utilizing the aforementioned calculation.

The rated horsepower for the efficiency dual-motor all-wheel-drive variant has additionally marginally improved, from 700 to 708 horsepower, as per the doc. The quad-motor model stays the quickest of all variants with 835 hp and a 0-60 miles per hour acceleration time of three.5 seconds.

How do these figures evaluate to different electrical vans available on the market? Take a look at our complete all-electric automobile value and vary comparability for insights. Additionally, go away your ideas in regards to the new EPA vary estimates for the 2023 Rivian R1S within the feedback.
