According to the document (which can be seen in PDF form here), CARB rates the Crosstrek Hybrid's Urban Dynamometer Driving Schedule electric range at 25.650 miles. For what it's worth, the Toyota Prius Prime with which this Subaru shares powertrain tech, has an EPA-estimated all-electric range of 25 miles and a highway electric range of 21.9 miles. The document also lists an "equivalent" all-electric urban range of 26.273 miles and "equivalent" all-electric highway range of 27.381 miles. ("Equivalent" range calculations come into play when PHEVs use a mix of electric and gas power at the same time.)
The Crosstrek, which will use Subaru's own 2.0-liter gasoline engine, doesn't appear to suffer a reduction in electric range compared to the Prius Prime despite its size, elevated ride height or all-wheel-drive system, which raises a lot of questions. The reasons are still unclear, as we don't have a lot of details about the underpinnings of the 2019 Crosstrek Hybrid, and we can't help but be skeptical about those figures. Will it have a bigger battery than the Prime's 8.8-kWh pack? Will the electric motor drive all four wheels, or will it only power one axle under all-electric power? What other mitigating factors could add efficiency and, in effect, range to this Subaru? Are these calculations, in fact, indicative of the yet-to-be-announced official figures? Of course, we'll have to see how the EPA's final estimated driving range shakes out before we draw our official comparisons.
We'll know a lot more when the 2019 Crosstrek Hybrid gets its official debut before the end of this year, plug and all.
