Priorities

:star: :star: :star:

Lap time at Ellisbury Grand Prix Circuit
A race car needs to be fast

Reliability
You need to be able to finish a race

:star: :star:

Price
Racing teams need to be able to afford your car

SVC
Your car shouldn’t bankrupt a team with repairs

Fuel Efficiency
Less fuel in the car makes it faster

:star:

Sportiness
Good handling means less mistakes

Design
A cool looking car will bring more attention to sponsors (interior recommended but not judged)

General design cues:

  • Don’t have extreme aero (big wings and diffusers) (use small-medium sized wings, and small diffusers and splitters if you want)
  • Keep it looking similar to a road car
  • Car should look sporty (no SUVs, Trucks, Vans, etc.)

Inspirations (Design Only!!):

This includes adaptive dampers, air/hydropneumatic and active springs.

I’m suggesting a maximum cylinder count of 6, with 4 cylinders being the absolute minimum.

So the base car should be a coupe or sedan, but not a convertible. But must it also have provision for two rows of seats (regardless of whether the rearmost row can accommodate full-sized seats or not) instead of just one?

I’m expecting cooling flaps to fall under this category.

first comment: this includes, springs, dampers and sway bars

  1. I’ll change it

  2. only one row of seating is needed. I will change it to say no convertibles

  3. yes

4

Why require longi? Most WTCR cars are transverse AFAIK…

5

Or you could allow both transverse and longitudinal engine placement, as long as the engine is in the front. AWD would still be banned for balancing reasons, though.

6

the cars are RWD, this isn’t supposed to be a touring car remake

7

I did change for it to be allowed if anyone would like to do that

8

Maximum downforce as in total of front axle and rear axle?

9

race car challenge? hell yeah

10

small diffusers ok? they’re on production model cars, like the bumper mounted one, not the GT3 style.

11

yes

12

also yes

Which should I follow?

14

This is the case for most models

15

the second number, if you set the restriction in the body-picker It won’t show bodies like that

16

Are there any restrictions on traction aids? Like GT3 cars use TC and the like.

18

There aren’t
