Help with Test Meanings

Hay everyone, this might seem stupid of me to ask, but I am always trying to play and perfect the cars but the more I've played the less I've understood exactly what some of these things mean or why their stats come out the way they do. I also wonder what a normal engine should be in the tests. All the parts highlighted in red are what I was wondering about and here are my questions.
1. What does that second chart mean?
2. Why are the lifespans so low? I don't know of a single car today that only gets 57,000 miles.
3. What does the Responsiveness actually mean?
4. What is the loudness calculated as? That's definitely not Decibels.
5. What does the Smoothness mean?
6. What car costs $845 a year? To only last 57,000 miles and have to pay $800 a year in oil changes seems a little dramatic
7. What are the Emissions calculated as?
8. What does the economy percentage mean along with the lb/hph?
9. I thought the RON level was just the fuel, what is the engine doing to change this?
10. Is the price and man hours normal? They seem very High.
I love building on the game but at the same time it would be nice to know what today's average car is at or what the standards are so I could know what I should improve. So does anyone know what the "Normal" or "Standard" numbers are for all these stats? I know that it's hard to say seeing that every engine is a different size and power, but there has to be standards or an average so I know how well I am doing with my design.
I feel like this engine is good, but at the same time I don't know what to compare it to or what some of those stats mean.
