It looks good, however, I would CLEARLY describe what you're going to study and what your sources and tools are in the first paragraph, that -- and asses your end conclusion a bit more.

Otherwise -- well done!
 
Looks good,.. though if I were ignorent to this type of info, I would want to know right off the bat what FF and MR was,...... don't wait until the second paragraph.

I would recommend spelling out the words "front engine-front wheel and mid engine-rear wheel" until you get to the FF and MR explaination. From there, the abbreviations are fine 👍

Good lookin report for the most part, you should score no worse than a 'B' IMO.
 
Here goes. This is a critique, and only my views. Please take what you can from this.

Everyone else is correct. Explain what FF and MR means sooner than you did.

Common misconception: FF cars are more popular because of "they are efficient". The lack of choice in the MR catergory would be a better thought.

FF cars are safer. What happens when you start to slide in an FF car? you take your foot off the gas, and the car corrects itself with minimal input by the driver. MR cars are easier corrected if you know how. Thats a problem with today's drivers. Not enough of them know how to drive good. But, that's another topic (Just ask Miata13B about stupid drivers).

You are comparing a 1999 beetle, with a 1991 NSX. A $20,000 car with a $100,000 car. You might look more at a Toyota Spyder (which you do later for other reasons). That is a small MR car that is comparable to the setup of a beetle. Unless your teacher has no idea, and you'd like to slant the opinion one way or another.

At the beginning of the paper, you and Bobby agree that an FF car will win in the twisty section of the track, ten before any proof is given (only theorys at this points) you have changed to "However, when the drag strip turns into a twisty and tight road, a MR car will also win. The answer again is because of weight distribution". Give a bit of reason why you've changed your stance.

If your teacher has any clue, he'll look at the picture of the SS and say "nice picture, but isn't the engine in the front?" Change the picture to a more appropriate car. Yes, it's appropriate to the piece of conversation (transfer of weight) but seems as misinformation in the overall subject matter.

"When you have more grip, you can accelerate faster." Say instead "When you have more grip, you can apply more power to the wheels, thus increasing your acceleration"

In the first paragraph or the Turning Ability section you may want to explain understeer and oversteer slightly different. Understeer results from a loss of traction at the front wheels of the car which corresponds to the car sliding nose first towards the far edge of the road. Oversteer results from a loss of traction at the rear wheels, resulting in the backend of a car traveling faster than the front which results in a "Fishtailing" action.

G forces need to be explained. Using that is akin to yanking a fact out of thin air.

All things considered, you've gotten a nice start. I'd say your 40% done. Another 40% in research and reworking the paragraphs, followed with another 20% of polishing it up (10% the writing, 10% the doucment presentation).

Keep us posted, and if you've need another review, let me know via PM.

As a final note, keep this in mind: A frog without legs can't hear. take a frog set it on a table, clap right behind it. Frog will jump. Cut off the frogs rear legs. Set it back on teh table, Clap right behind it. Frog doesn't move. Ergo "Frogs without legs, can't hear"

well, reading what you said here, i think i have alot more work to do, tnx DA!

edit: i basically just yanked out the part about the drag strip turning into a twisty course, cuz it just didn't seem to fit. I don't think i actually need an intro because people that come over to see my project will already want to read about it.... hehe
 
OK, i need some more help now
i need to find a picture of an mr car (any) doing a miniture wheelie (wheels slightly off the ground is fine)
 
HRD: It may be tough to find a picture of an MR car doing a wheelie, what you might do instead, is note that the picture is of an FR car, but you needed the visual aid to show how tires lift off when under heavy acceleration.

AO
 
Yeah, thats what i did.. i was editing yesterday, couldn't find any pics, so i just stuck w/ the ss but noted that the same happens to all cars when they accelerate, just not as drastic
 
That's an actual report for school? Wow, I only wish I could do something that good. In my opinion, I personally disagree about the windy road part, and here's why:
Although the FF has more stability due to the fact that all the power is coming from thefront wheels, it also is forced to have a smaller turn-radius (the wheels have less room because the engine's in the way). The MR car's greater turn-radius would cause it to maintain a higher speed around the turns than the FF car. Although stability would be an issue, to an experienced driver, it shouldn't be a problem.
