CSR 158 - Obaachan's Wild Ride

CSR 158 - Obaachan's Wild Ride


❀ Premise

Chihiro Hikari, 73, well-off widow of the CEO of a large tech conglomerate Kyocera Corp, is moving back to Hokkaido to be closer to her family. She’s quite eccentric, dressing in a much younger style than her contemporaries in Tokyo, and her demeanor can be ruthless or kawaii and bubbly depending on how well she knows you. She flourished in the shadow of her husband, sometimes being considered the puppeteer behind the company. The constant beeping of her notifications from her phone has given her the nickname Obaachan-P or Baachan-P amongst her friends and family.

In her transition away from the city, Chihiro has warmed to the fact that she’ll need a car to get around without the access to constant public transport. She does know some about cars, being a big fan of what was being offered at the Nissan Cherry stores and their cuter, slightly retro look that reminded her of her childhood. She’s enlisting the help of her grandson Hachi, who she knows is very into cars and would be helping her maintain whatever she buys. She has bought subscriptions to Young Auto magazine for his birthday for a while now, so she thinks he’ll be a good guide to what’s cool.

❀ Rules

TL:DR The year is 1998. Obaachan wants a fun, economical, sporty small car for driving around in the Hokkaido countryside and has enlisted her tuner culture knowledgeable grandson to help her pick one to buy.

Optional guidelines for More Realistic builds (mostly visual)

✧ Kei sized cars should have Kei colored plates. These are the black text on yellow background

✧ All other cars should either have the green text on white background Japanese plates or either of the two glow colors of Japanese plates from the mod (I know they’re newer than the '90s, but they’re still cool).

✧ 660 cc era Kei cars, like the ones we’d be dealing with, have size restrictions. They are at maximum 3.4 m in length, 1.49 m in width (rounding to 1.5 is ok for this challenge), and 2 m in height. I originally wanted to run this as a kei car only challenge, but the dimension limits severely limited the choice of bodies and I didn’t want the salt it would cause. They are also power limited to 63 hp.

✧ Most Japanese cars have amber/orange turn signals. They also do not require side marker indicators like USDM cars do (the ones that are at the corners of the car, not the ones further down the fenders or on the side mirrors). The lenses tend to be either amber or clear. It’s also not uncommon for more upscale cars to have a slight smoke tint to some headlight and tail light areas for a sportier and refined look. Case in point, the R33 generation skyline sedans.

✧ Cars not originating from a Japanese manufacturer can defy the 63 hp limit and still be classified as a kei vehicle if they meet the engine size and physical size limitations. Caterham did this with their 7 160 model, which in stock guise made 80 hp.

✧Here’s review of some of the cars listed in the inspos from the early '90s. The cars Obaachan is looking for are at least as sporty if not sportier than the top ones shown here.

❀ Priorities

🟉🟉🟉🟉🟉

✧ Design

✧ Realism: This is a CSR round, so realism is a very high priority. That being said, kei/kei adjacent cars have quite the variety of engineering options, so experimentation is encouraged. Stuff like transverse boxers will still net you a bin however. Sites like Carfolio, Automobile-Catalogue, and Wheelsage are all great resources when looking up car specs and visual details. Quirkiness isn’t a bad thing if executed well and with realistic choices elsewhere.

✧ Driveability: (Insert “granny’s got arthritis” meme here) Obaachan is in her 70s and would much rather have something easy to drive and not something she has to put her full weight into to get it to turn. Also she can drive stick, but prefers not to. Something with a “sport mode” would be more appropriate, according to Hachi.

🟉🟉🟉🟉

✧ Fuel Economy: Fuel stops are few and far between in the rural areas of Hokkaido. Obaachan really doesn’t want to be stranded in the hills somewhere when she’s out on a night drive.

✧ Performance: This will be determined by real world stats, not the sportiness stat. Keep in mind the class of cars you’re building here. 100 hp goes a long way when your car is under 1000 kg.

✧ Comfort: Again, Obaachan is in her 70s. She’d rather not have her bones pulverized over every little bump.

✧ Value for Money: A good balance needs to be struck between cost and features. Obaachan can spend up to her full budget, but would prefer not to. A cheaper car with the same features and good stats can easily beat out something more expensive. Go too cheap and feature light and she won’t even consider it.

🟉🟉🟉

✧ Safety: These are tiny, light cars, so this value will probably lower than expected. However, Obaachan doesn’t want a literal tin can to drive.

✧ Reliability: Obaachan needs to have this car be consistent, as it will be her primary mode of transportation. Hachi won’t always be around to help her with repairs and she doesn’t want to have it trucked down into Sapporo to be repaired at a dealer too often.

✧ Service Costs: Road tax can be hard to overcome for someone on a reduced income, so the less maintenance costs the better. The tax break for kei vehicles is included in this, as detailed in the rules tab.

🟉🟉

✧ Practicality: Obaachan is mostly going to be using this car to go shopping and occasionally with a friend on longer drives. It needs to have at least some sort of storage space beyond the passenger seat is needed. (This will be more from the car’s actual dimensions than the actual stat.)

✧ Environmental Resistance: If this was southern Japan, this would be less of an issue, but this is Hokkaido, the land of snow banks the height of one story houses. Keeping rust out is key in that sort of environment

🟉

✧ Emissions: While minor from a stats standpoint, it’s a very important thing in Japan due to population density. If you don’t pass emissions testing(not having all the sections in the fuel economy part of detailed stats show green), you will be binned

Does a large Rhania SUV fit the bill?

even if i was a dad with a family of 3 and a dog living in a largely car dependent area, i’d rather walk

The Rhania behind you: :face_in_clouds:

if you cant use spoilers, i will make a custom non functional spoiler

That is perfectly fine. This class of cars would occasionally have those for style reasons, rather than for downforce.

Are turbochargers expected??

Why do emissions have to be green in all years and not just up to 1997?

So cool that it’s even scary to participate

why scary
others peoples will make a car much better than yours?

No, I meant the task is difficult, so it’s quite difficult to enter

Because 1) japan is strict on emissions and 2) the challenge is in 1998. having the emissions only good until 1997 would be useless, and most cars should be futureproofed against rising emissions regs

This prevents their use for both aesthetic and performance purposes; however, using body moldings to simulate spoilers (usually ducktails) and side skirts is fine.

I read that as a maximum displacement of exactly 2000cc, and not 2000cc after rounding to the nearest 100cc.

Why is this listed twice? The second time it’s mentioned should be changed to “no semi-slick tires”.

And should there be an absolute maximum power limit for non-kei cars? If so, 100-120 horsepower would be an appropriate ceiling.

I’m assuming this refers to a hard and exact 2.30m maximum limit, instead of the wheelbase rounded to the nearest 0.1m (which would lead to the actual maximum wheelbase being 2.34m).

For cars that are from the wrong era, imagine an equivalent of them from 1998; if they’re too powerful, think of a less powerful version.

Correct.

That was an oversight on my part. Sometimes copying and pasting things leads to duplicates.

No. It refers to any body set that is labeled as 2.3 m being valid in this case. This is to allow for rounding on account of Unreal Engine being weird for body creators.

This shouldn’t be necessary. leaving it open allows for cars that don’t go the superlight route but still have similar performance to be entered.

its not restricted as LHC

Actually back then their standards weren’t really strict when it comes to just the limits - maybe their test cycle caused them to be so, but it’s hard to tell. Anyway, the 2000 standard, replaced in 2005 (so with a huge margin for the challenge) required:
CO: <0,67 g/km
HC: <0,08 g/km
NOx: <0,08 g/km

There were also additional levels that gave tax benefits to the users of such cars, and those lowered the HC and NOx values to 0,06, 0,04 or 0,02 g/km.

That makes sense, however it’s easier to go off of what the game uses and what the thresholds there are instead of checking extra 3 datapoints per car.

Well of course, but maybe the latest one isn’t the most accurate in reflecting that? TBH I’m not sure, as I don’t remember their values, but I guess it could be so. Just sth IMO worth checking.

Following up on emissions:

The new system introduces three different ways to interpret emissions. Headline figures, WES levels and passrate.

Headline figures are the raw quantity of each pollutant you put out per km, measured in grams or milligrams.
WES levels are intermediate value similar to EURO 1/2/3/4/5 targets or the EPA’s own levels.
Passrates are, as far as I can tell, the worst of your three emissions as mentioned against Gasmea’s standards when you measure the car using the WLTP Class 3 method. A 200% passrate means half the maximum HC, CO and NOx.

Fruinia begins mandating WES11 in 2005, for reference, and they are the first to do so… But you can see if a car passes WES11 from at 1995 onwards. Gasmea, meanwhile, requires WES10 in 2005.

Hshan’s figures are averages. The actual numbers, according to this source, final table, are 1.27 g/km of CO, 0.17 g/km of HC and 0.17 g/km of NOx. That’s about WES 9.5, so to speak.

Now, it’s worth noting that there are two different panes which can show green in all categories:


The engine pane’s emissions results. These are not what you should care about, but they are useful as they show which pollutant you need to deal with. Also, they depend on the attributes of the car, like weight, aero and gearing.

The fuel economy tab in detailed stats. These determine legality.

TLDR: The rules are correct, if a little bit indirect. These two images are from the same car. Your passrate in 2005 is your passrate against WES 10 standards - which coincidentally line up to be just a little more stringent than IRL Japan, but not by much.

One big thing to notify…
After I’ve seen you screenshot, it is the beta “Elisbury” one.
I’d suggest to have optional condition or base line rules based on the stable version, not rely on the latest beta for the sake of fairness.
In that case you can set the total emission no more than xxxx amount.
