The Plug-in Prius works just the same as a normal one, but with one big difference. The Plug-in's more advanced Lithium-ion batteries can hold much more charge, so if you top-up the power levels by plugging it into a normal mains socket for 90 minutes (hence the name), you can travel up to 12.5 miles on electric power alone. That boosts the average fuel economy to 108.6mpg, and drops CO2 emissions down to 59g/km.
It's just a shame we had to use up the electric power on the relatively easy bit getting out of Brighton – it would've been far more useful in the stop-start traffic in London later on.
