Design News - Captain Hybrid - Video: Our Prius Plug-In Test Drive
During our test drive, we got the advertised 13-14 miles of range. When we drove within that all-electric range, our vehicle estimated its own fuel efficiency at 99mpg. It should be noted, however, that even when we drove within the electric range, the vehicle autonomously shifted back and forth between electric and hybrid modes. The main reason was acceleration. When we stepped deep into the accelerator, the car shifted into hybrid mode for about 10 seconds until a constant velocity was reached, and then it switched back. After a low-speed, 4.3-mile circuit, the vehicle’s dashboard display claimed it had been in EV mode 75 percent of the time and in hybrid mode for the remaining 25 percent.
A longer drive was a different matter. As soon as we reached 60mph on a local expressway, the car shifted into hybrid mode and stayed there. The shift was seamless. During a 155-mile ride, the vehicle was in all-electric mode just 4 percent of the time. The fuel efficiency was still impressive, however, coming in at 56.6mpg.
