The Name Of The Game

In this challenge, your task is to make use of the nascent technology of turbocharging to make a fast, up-market sports car for the year of 1978.

We have made an example car for the challenge which can be found at the bottom of the post under the resources- tab, along with a few other goodies.

A Serious Headscratcher

It is not enough to merely take a coupe and slap a turbocharger on it. Because your car is going on the mass-market, it has to meet strict criteria for drivability, dependability and overall quality.

The requirements are tight, differences of even 0,1 will end up mattering.

Rules | Engine

The Meat Of It

Your engine should be a well balanced, refined solution to the problem of power at acceptable fuel economy. This means making the engine dependable, smooth and deceptively powerful for it’s displacement. How you achieve this is up to your discretion.

The requirements are as follows:

  • Engine model year of 1978
  • Minimum reliability of 60 points
  • Maximum loudness of 40 points
  • Maximum PU of 40 units
  • Engine must be turbocharged
  • Boost pressure must not exceed 0.8 bar or 11.6 psi
  • Engine must run 95 Premium unleaded
  • No Negative Quality

Practical Tips!

  • Run techpool and quality in the same place where possible
  • Displacement Trim is an easy way to eek out reliability
  • You can save weight and money by not using an intercooler
  • Your engine contributes a lot to Fuel Economy, focus on your fuel system

The Form and The Function

It’s not enough for your car to simply be fast, it has to be viable on the mass market. This brings compromises in sportiness for the sake of comfort, fuel economy, and ease of driving.

The requirements are listed below:

  • Model year must be set to 1978
  • Must seat at least 4 people, bonus points if you seat 5
  • Car has to meet WES6, meeting WES7 will net you bonus points
  • Combined fuel economy mustn’t be worse than 10L / 100km
  • Reliability must not dip below 54 points
  • Drivability has to meet at least 50 points
  • Sportiness of at least 12 points
  • Comfort must be at least 15 points
  • Safety has to at least meet 37 points
  • No Negative Quality

Practical Tips!

  • Techpool and quality walk hand-in-hand
  • We left extra leeway in comfort, eek out points there
  • The new reliability tab is your friend for nabbing points
  • The fuel economy can be met with clever quality placement

Rules | Budget

It Has To sell, Don’t It?

Financial constraints are a reality in auto-manufacturing, you don’t have all the money and time in the world to push the car to market, and your customers don’t have bottomless budgets either. Your car has to meet the financial goals outlined below:

But First, we need to set your techpool:

  • Set every techpool category to 3
  • You have 10 extra points to spread around
  • NO CATEGORY CAN EXCEED 6 POINTS
Money wise:
  • Max Approx. Cost of 20 000
  • Max Service Cost of 1350

How we score the cars

AKA: How you win

Your car’s score is made up of your “stat placements” and the edge you have over the competitor trailing you Your “edge” is the amount you are above in any given stat over the next best car.

The System in Detail

  • First, all cars are split into their stats

  • Then, the cars are ranked on each stat
    Then we do math:

  • Your “placement” score + the amount your stat is above the trailing competitor * 1 - 3
    the multiplier is removed for “easier” stats to avoid edge-cases

  • Then we add up your stat scores to get your final score

Your final score is the sum of all the points you got per. stat + the points you scored from the style vote

We disregard the following stats:

  • Offroad
  • Utility
  • Weight
  • Trim ET
  • Engine ET
  • Engine Weight
  • Total Materials Cost

Everything else is scored, more is better

The neat part about the system is that it also scores you based on how much better you are than the last idiot. We will adjust the system accordingly for future competitions based on results and feedback

Some Help?

Seeing the objectively rough rules, we saw it fit to give you an example car. We engineered it to be middle of the road.

Hello! I am reserving this comment space for publishing the style vote once that is ready.
For some reason, the formatting broke and now the background, which should be black, just isn’t. It is in the editor, but not in the post. Very fucking annoying, but I suppose that is what I get for trusting my stupid chud self. I’ll see if I can’t fix it

Either way, we need feedback, so give it as you go along if you at all can. Thanks, and try to enjoy the challenge even with the broken background color xD

Like look at this bullshit, this is what the post looks like in the editor???

I’ll forward your praise to the guy who came up with the idea, and made like 2/3rds of the graphics. We spent an ungodly amount of time on them :sweat_smile:

That refers to the tactic of increasing the quality for a specific tab to a level that matches the techpool allocation for that particular tab.

Also, the requirement for at least 4 seats in total is to weed out anything that is too specialized or exotic - and unless I’m explicitly told otherwise, the rear seats can either be of the smaller +2 variety or larger, full-size items.

More or less, the 4 seats minimum rule is for realism’s sake. I don’t care if the seats are cramped +2s. Though in my testing, running 4 full-size seats worked best

7

This is beautiful dude, and the graphics remind me of my favorite anime of all time. I’ll shell out some time to make something good for this. One little question though, do you have any IRL inspirations for this project (akin to other challenges)?

Thanks for the praise man, it’s nice to hear people enjoy them despite the broken formatting xD

We didn’t really look at cars as much as we looked at engines, early Audi 2.2 Turbo, Nissan L20ET, Z18ET the like. Some intercooled, others not so much. I think the tight rules point the engineering in a realistic direction

40 loudness is too low for a sports car.

Most cars run 2 mufflers, we tested and made sure that you can get a performance intake in spec if you upgrade the exhaust enough. Though that is on a case-by-case basis

11

40 is well feasible if you have two mufflers, just put a baffler on the first muffler and reverse flow on 2nd. Since all cars here are turbocharged their loudness is already lower than NA, coupled with these two you can get within 32-35 loudness

12

You know, I am more surprised that loudess was the first stat that got complained about. I would have thought that the reliability and PU requirements were far more limiting

13

I’m not arguing it’s difficult or unfeasible (which the other requirements might be after I start building), just lower than a typical sports car would be. OTOH, turbos do muffle a fair amount on their own. I remember testdriving an 06 Dodge SRT-4 and finding it remarkably civilized despite having no muffler at all, just a cat, resonator, and a bigass turbo.

I suppose we should keep that in mind for the next one. For now, the rules are final unless there is a very serious problem. I think the wording of “sports car” I used is a bit wrong too. What do you call a sporty, up-market GT car? I suppose just that.

15

2 door and 3 door bodies only, I assume? Any incentive to use a smaller displacement engine given the Japanese context?

You are free to use 4 and 5 doors as well, if they score better than they score better. The “Japanese Context” was kind of an accident too, you are free to build a car from any country.

As far as incentives for small displacement, not directly. I found a sweet spot around 2l, going above or below is fine. Figure out what nets you the best score and go with that

17

For future reference, this background thing is a known awkward issue with Discourse at the moment. CSS isn’t an intended feature; an update to Discourse introduced some weird behaviours around the details dropdowns specifically. Just sorta is what it is. If you want to be completely sure, send the draft to yourself in a forum DM.

I’ll keep that in mind. Still blows though, we designed the graphics with a black background in mind

19

Is there a max quality, or is it only a +6 limit on tech pool?

No max quality, run as much as you want. Engine quality is only really limited by PU, trim quality is only limited by cost. Just don’t dip into the negatives.
