…the clincher is the Prius’s reliability.
Ulaanbaatar may be the chilliest capital in the world. On a winter morning drivers must sometimes start their cars in temperatures below -30°C. Cars that run on petrol and diesel tend to sputter and die at such temperatures. The Prius can use its battery to power its electrical engine until the car warms up enough for the petrol engine to run smoothly—saving many a Mongolian from freezing frustration.
