The Cd is related to the drag force which is what effects top speed and fuel consumption. When the drag force on the car or aircraft is greater than what the vehicle's engine can overcome it has reached its top speed. (autos of course also have to overcome rolling resistance) Since drag opposes the vehicle's motion, the engine must make up for that by burning more fuel. Anyway, since the geometery of an auto is rather complex, the Drag,pressure coeffiecent,etc is either found experimentaly, or using a numerical method.  anyway for flow around a cylinder the drag coeff is:              Cd = d/(q*2R)         where d is the drag force, q the flow velocity and R is the radius of the clyinder.    To get a rough (very rough) estimate, you can set R at 1/2 the car's width, q at the car's speed and knowing the Cd, find the drag force that the car would need to overcome.

Hey all,   I'm looking at buying a new car, but I'm confused about the insurance coverage.  This also applies to my existing car insurance policy.  Does anyone understand what the "Limited Tort Option" means.  Will it lower my rates if I opt to have it, or will it be more expensive if I opt to have it?  What does it do for me (in layman's terms please)?  Is it a good deal or should I ignore it?  I'm not the type to sue anyone at a drop of the hat nor am I the type to report every little ding to the insurance company as a vandalism claim.  Please help.    Thanks in advance.

When a friend of mine went shopping for a small sedan a few years ago, she brought me along as a token male so the salespeople wouldn't give her the "bimbo" treatment. Her first choice was a Mazda 323, and second choice was a Nissan Sentra.  We went to a Mazda dealership and described what "we" wanted.  We started negotiating on the price, and the salesdroid kept playing the "let me run this price by the sales manager".  After playing the "good salesman, bad salesman" game, we finally told him that if he didn't have the authority to negotiate a price, perhaps we should be speaking directly to someone who did.  He brought in the sales manager who proceeded to dick us around with every trick in the book.  (Read Remar Sutton's "Don't Get Taken Every Time" for a list.)  Finally, after playing a few more rounds of "you'll have to work with us on this price", also known as "each time you come up a thousand dollars we'll come down ten", the salesmanager gave a signal to his two sales cronies, stood up, and said "well, we can't come down any more so I guess we can't help you" and they trouped out of the room, leaving us sitting in the salesman's office all by ourselves.  Hmm. I'd read that sleazy salesmen sometimes bug their own offices so they can leave and listen in on couples discussing the sales offer, and I mentioned this aloud to my friend while we were sitting there wondering why they would leave us in the office instead of showing us to the door.  For lack of anything better to do, I picked up the phone on the desk and called another Mazda dealership, asked for a salesman, and began discussing what kind of price they would consider.  A few sentences into the conversation, Mr. Salesmanager broke into the line (!) and began telling me how rude he thought it was that I would call another dealership from "his" phone!  I said that since he'd announced that our business was over, he shouldn't care, and every time I tried to talk to the other sales guy the sales manager would drown out our voices with his own.  (How did he know that I was using the phone, anyway?)  Finally, I hung up and we headed out of the showroom. Sales manager and cronies come out of a little unmarked room and he begins to berate us again.  We say that we won't bother him anymore, we're going next door to the Nissan dealership.  Then comes the part I wish I could have videotaped.  As we go out the front door, the sales manager SHOUTS across the entire showroom, customers and all, "Go ahead!  You DESERVE to buy a Nissan!" So my friend bought a Sentra.
My wife and I looked at, and drove one last fall. This was a 1992 model. It was WAYYYYYYYYY underpowered. I could not imagine driving it in the mountains here in Colorado at anything approaching highway speeds. I have read that the new 1993 models have a newer, improved hp engine.   I'm quite serious that I laughed in the salesman face when he said "once it's broken in it will feel more powerful". I had been used to driving a Jeep 4.0L 190hp engine. I believe the 92's Land Cruisers (Land Yachts) were 3.0L, the sames as the 4Runner, which is also underpowered (in my own personal opinion).   They are big cars, very roomy, but nothing spectacular.

When do the new M.benz "C" class cars come out? The new nomenclature that MB has adopted will it only apply to the "c" class cars or will it also apply to the current "s" class cars. Does any one know what will replace the current 300 class since the "c" class will be smaller and more in line with the current 190.  Another question, Is BMW realising a new body style on the current 7 series and 5 series. They seem to be a bit dated to me.

Hello Netters,  I would like to find out information about a device that is used on vans and trucks. This device is a step that hooks onto the tire and folds up for storage. I've seen this device on TNN's Shady Tree Mechanic. I would like to know if it is a good product and I would also like the price and address of where I can purchase this product.  Thanks,
Does anybody have any information on the second generation Broncos? (I'm not talking about Bronco II's, I'm referring to the Broncos that began production in 1978 based on the F-150 chassis I believe)  I need to know what to look for, can the tops be removed from all models, how easily can that be done. Also, what kind of price range should I be looking at? (i.e. what is blue book) I'm in college right now, and would like a Jeep. Unfortunately, I've got a bit of a ride to school, and I need to carry a lot of junk to and from the dormitory in the spring/fall. I think that the Bronco (with the removable fiberglass) would be a better (read "bigger") choice than a CJ-5 or CJ-7.  Even better: anybody in the Maryland/Virginia area interested in selling one?

DeSoto's first year of manufacture was 1928, so this may indeed have been an export special, as left hand controls were standard here by then.
Hi Javier, (how are things at Corp, my old stomping ground was c-level?) Vibration when applying the brakes can be caused, on disc brakes at least, by warped rotors. When the brakes are applied, there results uneven pressure on the rotor.  Turning the rotors by a brake shop will remedy this problem as long as there is enough rotor width left for turning (i.e. within spec). There could be some possible front end suspension problem but a brake shop should be able to confirm warped rotors by a visual inspection which is free.

Seriously though, every 2 years you should have this done. Brake fluid absorbs water over time, the water becomes steam when the fluid gets hot, and steam compresses. You'll also have better luck with the longevity of master cylinder, calipers and brake lines.
Yeah, but I hate to follow them with the exhaust at ground level. Not all diesels are well maintained, either, it seems they run for so long that people keep them going long after the top end is worn out.

They are popular vehicles.  You don't see a lot of previous model year ones sitting on dealer's lots for any lenghth of time after the new ones are out.  The things sell, they are popular.  Because they are popular, and high-priced new, they are high price used, very simple.  I knew they were overpriced when I bought it... I knew they had a terrible  reliability record when I bought it.  But I didn't expect anything like I got, especially with a dealer network unable to repair it.
