Prius Fleet From Annual Sales Minus Losses
The following are the annual sales of Prius in the USA per year as reported by Wikipedia from Toyota USA press releases.
However, we take out 3% each year retired ("In 2005, about 6.5 million automotive vehicles were
retired from use in the United State; ..." Emilio Brahmst, Manufacturing, Engineering & Technology Group,
Center for Automotive Research, 'Copper in End-of-Life Vehicle Recycling' and "242,721,000 registered
vehicles", Table 2, DOT HS 810 623,"Traffic Safety Facts 2005 Data", NHTSA, 6.5/242.7 = 2.7%.)
A lower annual loss rate for the newer, Prius will improve the Prius accident safety rate and
may be obtained from Toyota USA:
| Year |
Sales |
After 3% loss |
| 2000 | 5,562 | 5,478 |
| 2001 | 15,556 | 15,322 |
| 2002 | 20,119 | 19,817 |
| 2003 | 24,627 | 24,257 |
| 2004 | 53,991 | 53,181 |
| 2005 | 107,897 | 106,278 |
| 2006 | 106,971 | 105,366 |
| 2007 | 181,221 | 178,502 |
Prius Fleet Vehicle Miles
To calculate the fleet miles traveled each year, we use the following assumptions:
- 15,000 miles per vehicle per year - this is the annual miles the EPA uses to calculate per vehicle travel.
However, Quality Planning, 388 Market Street, Suite 750, San Francisco, CA 94111, (415)369-0707, reports that hybrids drive an extra 2,000 miles per year in "non-commuting miles." This would make hybrid electrics seem safer but without independent confirmation, we will use the more conservative, EPA 15,000 miles per vehicle per year.
- First sales year, only half the vehicle miles - this assumes the sales are split evenly across the year so only half of the vehicles drive their annual miles.
- Same 3% loss of vehicles per year - losses remains the same, year after year.
With these assumptions, we can calculate the annual and cumulative Prius fleet miles per year:
| total for year | fleet mi (end of year) | fleet (for year) | 2000 | 2001 | 2002 | 2003 | 2004 | 2005 | 2006 | 2007 |
