Toyota needs to get 30 miles EV only range at 30C or -10C and then IMO they've cracked the nut on the Prius type units. 13 miles is not quite enough.

LOS ANGELES -- With the retail launch of the Prius plug-in-hybrid version a little more than a year away, Toyota is getting in some last-minute testing.
Toyota is lending 163 plug-in Prius prototypes to universities, utilities and car-sharing services such as Zipcar.
The largest group of 18 Priuses went to the University of Colorado-Boulder through Xcel Energy’s SmartGrid project.
Other groups receiving plug-in Prius prototype loaners include the Silicon Valley Leadership Group, Portland State University, the California Center for Sustainable Energy and the Clean Cities Coalition of New York.
In trying to get higher-mileage vehicles into the rotation, Toyota also has lent eight vehicles to Zipcar’s fleets in San Francisco, Boston and Portland. CuseCar, a car-sharing program in Syracuse, N.Y., also is participating.
“We wanted a lot of various-use cases,” said Toyota spokeswoman Jana Hartline. “Some might be cycling through households for day-to-day driving. Some might be used on service calls, like with San Diego Gas & Electric. Some will have access to daytime charging, others to Level 1 charging.”
The vehicles will be on loan for 12 months, with the consumers having the option to extend to 18 months. During the loans, the Priuses will have data uploads performed at Toyota dealerships to analyze driving and charging patterns. Drivers also will participate in surveys conducted by Toyota.
Although the Prius PHV is basically finished, as far as r&d is concerned, some last-minute tweaks can be engineered. Toyota is considering tinkering with software settings to extend the vehicle’s 13-mile EV-only range. It also is working on a setting for the driver to select when he wants the vehicle to switch to EV-only mode, rather than requiring every trip to start in EV mode until the battery is exhausted.
The Prius PHV is powered by lithium ion batteries and can be charged from a standard 110-volt outlet in about three hours. It can drive in EV-only mode up to 62 mph. Once its EV-only range is exhausted, it gets about 50 mpg in hybrid mode.
