New documents reveal that the upcoming 2019 Subaru Crosstrek Hybrid could have a best-case scenario of 25 miles of all-electric range—unadjusted—according to numbers submitted to the California Air Resources Board (CARB).

That puts it in the hunt with other plug-in hybrid small hatchbacks and crossover vehicles.

The California documents, first obtained by Autoblog, show results from the EPA's urban dynamometer driving cycle, a lab test which by itself has been known to produce somewhat optimistic numbers. The actual EPA range rating will be subject to an adjustment factor and could be significantly lower.

Subaru developed the Crosstrek Hybrid in conjunction with Toyota, using Toyota's hybrid drive system, which likely means it will have the larger company's electronically-controlled, planetary continuously variable transmission. It is expected to offer Subaru's typical standard all-wheel drive and elevated ground-clearance, however, so many observers expected more modest range numbers. 

When Subaru last sold a Crosstrek Hybrid from 2014 to 2016, it barely improved on the fuel-economy of the non-hybrid Crosstrek and seldom ran on electric power.

The company hasn't released any specs, so the configuration of the all-wheel drive system isn't entirely clear—or whether the Crosstrek has a larger battery pack than the 8.8-kilowatt-hour unit in the Prius Prime.

The Crosstrek Hybrid is scheduled to debut later this month at the LA Auto Show, potentially at the same time as a rumored all-wheel-drive version of the Toyota Prius hybrid. Toyota, however, may not offer all-wheel drive on the Plug-in Prius Prime, which has 25 miles of range.

Either way, the new Crosstrek Hybrid makes no mention of its plug-in capability in its name, much like the Chrysler's Pacifica Hybrid minivan. Perhaps having some plug-in range has become the new minimum entry point for a vehicle to be called a hybrid.
