Are Manufacturers mpg figures possible?

When i had a gen3 prius the official mpg was 72.  In the summer i could get over that but the winter was a different story.  I was doing 20,000 miles a year and averaging 65 mpg.

the official figures were mandated to be set with an air temp of 20-30C (typically 25C).

Are they possible yes you can even beat them, but that would mean you wold need ideal conditions as in low car load,proper tyres, proper mix of open road/highway/city and proper road conditions.

look my Yaris is stated too have average consumption of 47MPG yet im avaraging 40MPG by doing very short trips
