But you can never know.
Go test drive a Toyota Crown [0] — it's 30mpg hybrid with 345hp
For reference, I drive a 209hp Camry [51mpg+] =P
Full EV's whilst not having great highway mileage, still get excellent mileage compared to a full ICE when in and around the city. If you have a plug in hybrid, I don't really see the point in having to charge a battery and put petrol in the car.
I don't care so much on the environmental side, however for a hybrid you still have an engine that consumes petrol, as opposed to just having a larger battery. Which is then a petrol engine, plus a transmission and clutch which require maintenance just like any other ICE.
Lastly here in Australia a full charge only costs around $20-35 as opposed to around $80-90 for a full tank of petrol.
None of the Toyota Hybrids have either (instead, a Pn10 [n=6,7,8] orbital gearbox [0]), but they do have the ICE maintenance requirements. Conversely, the inevitable battery replacement is much less expensive on a hybrid.
Fun fact: the main electric rotor redlines at 17,000+ RPM

You can do either/and, depending upon driving style. For example, if you mostly drive locally you probably don't ever need to gas it up — but be sure to use ethanol-free fuel if so (to not gunk up fuel system).

I know it's a mass-market site but this level of reporting is just insulting. Here are the actual numbers from the paper:
> We demonstrate lithium metal batteries achieving a 5–70% state of charge (SoC) within 12 min over 350 repeated cycles at a 4C (8.4 mA cm−2) charging rate, as well as high-energy designs delivering projected energy densities of 386 Wh kg−1 reaching a 10–80% SoC within 17 min over 180 cycles.
