Real Racing 3 Car Comparison Table #0 : Background and How to make and read the chart

At Firemonkeys RR3 forum, there was a question about how the car is enhanced by upgrade. For there are so many combinations from Engine to Tire, it is simplified as 3 stages, such as Purchase(pure),  R$ upgrade, and Gold+R$ Upgrade.

It is required to choose among 3-4 cars in each event. Generally, the right most car is the best and there can be 1 or 2 more cars which worth buy and investment. Again, to simplify the chart, only 2 cars/event from the right are analyzed.

And also, to optimize the chart, events are grouped into 5 zones as below.

• Class P : Low-end 
• Pure Stock Challenge
• Road Car International
• Global Production Pursuit
• Prime Production Match UP
• Street-Spec Skirmish
• 6 Cyl Annihilation Series
• Class P : High-end (with some low-end Class S cars)
• Performance Rumble
• Everyday Heroes
• V8 Muscle Hustle
• Coupe Clash
• Deutsch Duell RWD 
• Open Revolution
• Class R : Racing Version
• V10 Grand Open
• GT3 World Series
• GT1 Grand Tour
• Global GT Clash
• East/West Showdown
• Accolade Open
• Class S : Low-end
• Supercar Masters Series
• Moddern Sports Classics
• Pro/AM Supercar Club
• V10 Showdown Series
• V8 Performance Grawl
• Class S : High-End
• High-Rev Rush
• Vanguard Challenge
• 12+ Cyl Slam
• Supercar Elites
• Zenith Series
• Speed Daemon

A car has 4 factors in Real Racing 3, which are Max. Speed, Acceleration Time, Break Distance, and Tire Grip Force. They need to be normalized to be drawer in one chart. and also 2-D chart can display only 2 factors, so the factors need to be grouped.

1. Normalization

  1.1 convert to the time value
       - Max speed -> time to race 1 km
       - Acc. time -> time to accelerate from 0 to 100 kph
       - Break distance -> time to decelerate stop from 100 to 0 kph
       - Tire Grip -> time to race 1 km of arc with 100m radius (usually 2x~3x of straight case)
  1.2 normalize by median
       - For each Zone, every factors are normalized by 'Median / Value'
       - It is because the values are 'time' and the smaller the better.

2. Grouping
  If you read my previous analysis, it has the same logic.
  2.1 X axis : average of normalized max speed and acc. time. A point at right side means the car is easy to overtake others at straight.
  2.2 Y axis : average of normalized break distance and tire grip.  A point at upper side means the car can maintain speed at corners.

Now, it is time to enjoy the chart via following blog posts.
