OK... but is 200 lbs enough to make much diff in fuel
economy?

Just curious how that weight/efficiency curve
looks..... I am engineering student

Probably more noticeable in stop & go driving, since the additional
weight has to be brought up to speed.  

Apparently the major manufacturers think a few pounds is important:
Toyota advertises a "built-in bedliner" on some of their pickups - but
what they really mean is "we replaced the metal bed with a plastic
one".

My 2008 Tacoma (4 cyl, 4 speed automatic) does about 20-21 city and
26-27 highway (with improvement as you drop below 65mph).  The Tacoma
could use a 5 or 6 speed automatic - it could get another 2-3 mpg both
city and highway with proper axle and transmission ratios.  My
personal vehicle had been a 4 cylinder with a 4 or 5 speed manual
transmission for 25+ years until this purchase - the automatic is a
concession to the aging of my body (and the hardware in my back).

correction/whoops!

I can not  believe I overlooked this!!!  The lightest
car in the USA is not the 2009/2010 Toyota Yaris
but the 2009 Smart Fortwo (Pure 1.0L 3cyl 5AM)
whose curb weighs is only 1808lbs compared to
the 2010 Toyota Yaris  which is 2340lbs.  A
lighter curb weight by itself is not an absolute
energy efficiency advantage though. For example,
the  2009 Fiat Panda 1.1 has a curb weight atleast
100lbs more than the Smart Fortwo but it get
better mileage than a Smart ForTwo using a regular
gas engine and if you use a diesel engine its
mpg figures are comparable to a 2010 Prius!.
Yeah - its not available in the USA but it shows
how fuel efficent a regular ICE production car
could be. <sigh>

Usually these gadgets are not allowed into the USA due to safety standards
they cannot pass. Weitgh would imply more metal and strength of the box,
usually. I did say **imply** LOL

I wonder what the old Mini Minor came in at. Not the new monsters that are
twice the size and weight (I am sure)
