The Rivian R2 hits an identical 105 MPGe combined rating to the Model Y Performance in real efficiency testing, even though it packs a bigger and heavier body.
Rivian R2 vs Model Y Efficiency Breakdown
I dug into the numbers from the latest tests and the headlines claiming the Rivian R2 matches Model Y efficiency are only half the story. The launch edition Rivian R2 Performance All-Wheel Drive posts 105 MPGe combined. That lines up exactly with the Model Y Performance efficiency at the same 105 MPGe figure. But the comparison skips over the fact that the Model Y lineup has far more efficient variants available.
The standard Model Y All-Wheel Drive reaches 123 MPGe, and the rear-wheel drive version climbs to 138 MPGe. Those numbers put the Rivian R2 efficiency rating in a different light when you compare apples to apples.
Key Specs Side by Side
| Model | Efficiency (MPGe) | Range (miles) | Drivetrain |
|---|---|---|---|
| Rivian R2 Performance AWD | 105 | 330 | AWD |
| Model Y Performance | 105 | 306 | AWD |
| Model Y Standard AWD | 123 | N/A | AWD |
| Rivian R2 AWD | 99 | N/A | AWD |
The Rivian R2 range comparison still favors the newcomer. Its 330-mile estimate beats the Model Y Performance by 24 miles even at the same efficiency level. The boxier SUV shape and higher ride height of the R2 deliver real-world presence the Model Y simply lacks.
Why the Numbers Matter for Buyers
When I look at the Rivian R2 vs Model Y efficiency results, the takeaway is clear: Tesla still leads on pure efficiency in non-performance trims. Yet the Rivian holds its own where it counts for buyers wanting actual SUV capability. The 20-inch wheels on the R2 drop efficiency to 99 MPGe, showing how wheel choice affects the final rating.

Who Should Choose the Rivian R2
Go with the Rivian R2 if you need the extra ground clearance, boxy utility, and longer range at the performance efficiency level. It feels like a proper SUV rather than a lifted hatchback.
Who Should Choose the Model Y
Stick with the Model Y if maximum efficiency and lower price matter most. The non-Performance versions crush the Rivian R2 efficiency rating by a wide margin.
Bottom Line
The Rivian R2 proves it can match Model Y Performance efficiency while offering more range in a true SUV package. For many buyers that trade-off is worth it.
