A Crossover is a vehicle constructed like a car (unibody) that looks like a pickup, SUV or van but does not have a true frame which legally defines a truck. Honda does not make a truck, they are all unibodies which is why their 4x4 is not serious for off-roading (they have a stamped steel welded "frame"). Unibody construction is built without a frame, their strength is in the shape of the floor pan (lower side rails and transmission tunnel) and the roof pillars. That is why cars have crumple zones and trucks do not... frames don't crumple. And that's why convertibles are generally heavier then hard tops, they have to add sub frame connectors to build back the lost strength. Ford Flex gets it's name, if I recall correctly, from being able to use flexible fuel options, various levels of ethanol higher than the typical 10% now available everywhere. Ford Rangers have been available with flex fuel options for almost ten years, the 3 liter six with the little leaf and road badge on the tailgate. Some flex fuel vehicles can run on very high levels of ethanol, but burn twice as much of it per mile traveled. Imagine filling the tank every 150 miles! BTW, ethanol is a total ripoff. Alcohol has half the latent energy content (BTU's, if you will) of gasoline so mileage suffers. Plus the increase in corn production has run up food prices and is killing the Gulf of Mexico where the all the fertilizer run-off from the Mississippi dumps. This week the east coast of Florida is getting another red tide bloom, something that never happened until a few years ago. My friends in Georgia always comment how their gas mile drops when they buy gas in Florida. I have tested and found that it costs me one and half mpg, and I have tracked every gallon of gas I've bought since 2003. And yet we pay for 'watered' down gas which the subsidized with your tax money! We are getting stuck three ways with this deal and now our leaders what to up the levels to 15%, which might even destroy the rubber fuel system parts in cars built more than a few years ago... talk about boosting cars sales, sales tax and road taxes all at once! Burn more fuel to go the same distance but increase the hidden costs with taxes. And ethanol production puts more carbon dioxide in the air than just burning highly refined gasoline, so the net gain is negative no matter how you measure it with ethanol. To me, the answer to reducing oil dependence must include tax penalties for vehicles over 6000 pounds and to build neighborhoods designed for bicycles and pedestrians, like green ways and central shopping hubs. The talk of reducing "green house" gas emissions by legislating tougher laws is ignorant. An extremely efficient engine producing almost no hydrocarbon waste will get better mileage and produce the highest levels of carbon dioxide... CO2 is the by product of clean burning! If we reduce combustion efficiency by law, we reduce mileage and increase hydrocarbon (toxic) waste just to "reduce" CO2. How about we reduce CO2 levels by not cutting down all the trees that use it to produce oxygen we breathe? Or is that too much for our elected officials to fit into their political games? Congress's laws do not trump the laws of chemistry and physics. It is not possible to reduce CO2 levels AND hydrocarbon levels (and oxides of nitrogen, the other regulated tailpipe emission) without reducing the amount of weight moved per mile per day. That means a big diet of both vehicle weight and daily miles driven. We can each help by cleaning out our trunks, pump up our tires, and don't accelerate or brake hard to save gas. And don't drive your engine hard until it is fully warmed up, both for efficiency and for longevity. Find the recommended tire pressure in the handbook or the door jam. The pressure on the tire is the maximum for the tire when carrying maximum weight, not the pressure for a normally loaded vehicle. It amazes me how many minimum wage tire changers think that my vehicle needs 50psi (max on the tire) when the owner's manual says 30psi. Sorry to rant on about this, but I have found that most people don't know this stuff, and my hope is that more people learn that this will make a difference to us all.
