Can a moderate sport car be tuned or modified to compete with an exotic sport car?
Tesla
Kind of a weird question. I have to write a paper at school where I try to prove a thesis. I have always wondered personally if a more moderate sports car (such as an audi R8 aston martin db9 or Honda NSX) can be tweaked or modified to hold its own against more exotic super cars like lambos or Ferraris, Mclarens, SSC etc.. I only have a basic knowledge of cars, how torque and horsepower work, what's ideal when trying to build a fast car, and I understand that some cars can compete in theory (like driving in a straight line on ideal roads) but not when considering turning or other real life situations. I would like to know what type of modifications can be done or are ideal, and if they would give any of the examples listed a fighting chance against say a ventador or Ultimate aero or something of similar stats
Answer
The modifications would fall into area's of:
1. Suspension
2. Aerodynamics
3. Power.
Suspension includes brakes, shocks, springs and arm lengths.
Air management is needed to keep the car from lifting and reduce aero drag when possible and having a way to produce air drag if needed.
Power is needed for raw speed.
Now horse power is needed- this is just an expression for how much weight is being moved a second. For a 2000 lb. car to go 210 mph it takes a specific amount of horsepower when aero drag ins considered constant. But it is not- at about 50 miles per hour air for resistance purposes is more like a fluid then air. This is why a straight formula for horsepower and top speed does not work. The actual resistance increases and with the right formula's compensation can be made for air drag.
Torque is the ability to effect a change, this determines rate of acceleration.
So to match acceleration rates- it will take torque, to match top speed takes horse power. To decrease the amount of horsepower needed air management becomes important.
Now the reason it is not done on a regular biases is simple a Honda no matter how fast is still a Honda. The amount of dollars needed to make it perform like a super car just is not worth the bragging rights.
Keep in mind Super cars are not that practical and are just toys.
Those who have the money to sink into a R8 and the like to make it match other super cars performance would just go buy the real thing.
In all reality a Lotus would be just as much fun and a lot cheaper.

Why can a small sports car negotiate a winding road easier than a larger car?
How are the ideas of Centripetal force and Circular motion evident in the fact that small sports cars can negotiate a winding road easier than a larger car?
Answer
The ideas of cent. force and circular motion as applied to a sports car vs. a larger car have to do with the tendency of either car to slide or rollover due to cent. acceleration which is applied by the road to the tires. Sliding resistance is primarily about tire friction, and not necessarily different for either car. What is more likely to be different is the rolling tendency, and as an earlier answer said, this is improved by a lower center of gravity. (Here I'm referring to rolling over, not just rotating about the longitudinal axis in a turn, which a stiffer suspension can remedy in either car.) But a higher cg is OK if the car is proportionately wider; it's actually the ratio of these measurements that is important, as the diagram of the sideways centripetal and inertial forces in the reference can show you.
