GM Planning Aluminum Body Pickup Trucks

You're right about aluminum corroding. Aluminum "rust" is white and occurs much more slowly than iron rust occurs -- but it does occur. Alloying magnesium in with aluminum makes it much more corrosion resistant. I'm sure Ford & GM (and eventually Ram) have spent lots of time working out the corrosion problem. One solution may be some kind of base coating to seal the atmosphere away from the aluminum. Or they may just rely on the paint. About your diesel . . . have you seen the new Ram 1500? It's Truck Trend's 2014 Truck Of The Year. It has a 3.0L V6 turbo-diesel option for $2800. It comes with their 8-speed auto. With this engine & tranny, the 2wd model (either extended or crew cab, can't remember which) gets 28mpg on the highway. Pretty damn good, huh? And they say that diesel engine is really, really quiet. Truck Trends couldn't say enough good things about that little diesel engine. I'm amazed at how good this new generation of diesels is.

deck said, "Aero dynamics doesn't really come into play until you reach speeds of 90 or above." That is absolutely and totally false. You're welcome to your own opinion but you're NOT welcome to your own set of physics. Aerodynamics becomes very significant at anything over 30 - 35 mph. At normal highway speeds of 60 - 75 mph, aerodynamic drag is THE largest source of drag on a vehicle and is the largest consumer of fuel. It's greater than tire rolling resistance and mechanical losses and therefore causes the greatest hit to fuel mileage. At highway speeds, aerodynamic drag affects mileage more than mass does; in stop-and-go city driving, mass affects mileage more than aerodynamics does. The question is . . . where did you come up with such a bewilderingly absurd and false idea??? Did your semi-illiterate uncle Cletus tell you that when you were seven years old? You said, "We buy trucks to haul stuff and also to be men haha." I haul so much stuff that a truck is the only option for me. In fact, I've never figured out how any household can get by WITHOUT a truck. To me, that's a real head-scratcher. I'll never forget walking out of Best Buy and seeing a young yuppie couple with their tiny little black VW Passat parked by the curb. They had the trunk up and a large screen TV sitting on the sidewalk and they were clearly stumped as to how they were going to get that huge TV into their dweebish little Euro-trash econobox. I'm sure what they did in the end was call one of their gun-totin' redneck friends (like me) and ask him if he'd come haul their TV to their apartment. I have nothing against econoboxes, but not having a truck FIRST makes no sense to me. As far as being a man goes . . . I'm a man with or without my guns, with or with or my dirtbike, with or without my truck, with or without anyone else's approval. The source of YOUR manhood is in question. You said, "If you want to save gas get a car." That statement is so impertinent it doesn't warrant a direct response.
