AGC 28: Reflex

The year is 2018, and a construction conglomerate by the name of Kuroishi Corporation has been hard at work on their latest pet project for the past decade. Partially funded by a number of bored American elites and located in the Mojave Desert, the so-called "Reflex City" is a vast cityscape inundated with roads, just like any other big American city.

What sets it apart, though, is its total lack of inhabitants and even basic urban infrastructure. It seems Reflex City was designed from the outset to be a ghost town. But why’s that?


As it so happens, Reflex City is actually a multitrillion-dollar set for an upcoming fictional game show called Reflex, itself the centrepiece of an arcade racing game of the same name.

Reflex features high-stakes street races with both money and glory on the line. These races are explosive in a literal sense, as each race course is rigged with remotely-triggered traps that contestants can use to create obstacles for their opponents—or simply stop them dead in their tracks. The traps are only available to racers who earn enough points by driving with style (drifting, slipstreaming, or otherwise).

At the centre of each race are the heavily reinforced custom-fabricated vehicles, as well as their drivers. The developers have come up with five fictional manufacturers for outsourced studios to create designs for. Most importantly, though, to go with the lofty ambitions of those behind the wheel, the cars should boast loud, aggressive styling, intended to attract attention with or without fireballs surrounding the car.

The explosions may play a crucial role in making Reflex such a thrill, but the cars need to look the part too, like they were designed to race through a rain of rubble and scrap metal. This holds especially true for trucks and SUVs, the design of which should immediately convey the ability to shrug off shockwaves from explosions as if they were the wind from a cheap handheld fan.

While no one in the world of Reflex would dare to bring a light sports coupe to a supercar fight, it’s equally as disappointing when said supercars can barely outrun early-game trucks. Speaking of trucks, they fill the combat racing equivalent of tanks in RPGs and shooters, so trying to make one that can supposedly outmaneuver and out-accelerate a GT car on the same tier won’t do you any favours.

While it’s true that more power translates to more drifting and thus more points, keep in mind that different power levels correspond to different tiers. DLC aside, under no circumstances will the player get to start out in a fire-breathing wedge with a twin-turbocharged 1200-horsepower small-block.

The cost cap is a balance thing, and the developers have no plans of any sort to add any overpowered DLC cars. Nothing’s stopping you from building an early-game car instead of the 100% completion reward with stats out the ass.


⬣ Elite vehicles won't be available to the player until the game's halfway point. As such, higher performance and more aggressive vehicle types are expected.

⬣ Most of the supercars in Split/Second ride on what are effectively dubs with almost comically low-profile tires. For the sake of the challenge, I would prefer that road car submissions use the same wheel arch sizes that the bodies come with (including morphs, of course), though I won't dock points for wheels and arches that are just a bit on the large side. Provided, of course, there isn't too much or too little clearance between the wheel and the arch.

⬣ A livery is by no means required, but can really help make the car look believable as a race car. Of course, I don't blame you if you can't be bothered to add one.

⬣ Don't limit yourself to any sort of archetypes related to the brand you've chosen, since all of the brands lack any sort of design language other than being modern and aggressive. For example, the cars under the Ryback brand in Split/Second are a mishmash of retro-styled pony cars, blocky yet angular pickup trucks, and even mid-engine hypercars angular enough to rival the Lamborghini Aventador. Cobretti is much the same, with some of its cars looking Italian, others coming off as German or British, and one—the Iridium—looking rather American.

⬣ Should you decide to build a truck or ute, there are two recommended approaches: reduce the ground clearance with a racing body kit (à la Ridge Racer 6's Class 4 Danver Hijack), or jack it up and put beefy offroad tires on it. Using the advanced trim settings to move the engine behind the cabin isn't required, but certainly isn't out of the question, as the Ryback Tornado proves.

…and what are the criteria that will be considered to decide a victor? As someone who hasn’t done any of the AGCs before.

Also, reasoning for bans on FWD cars? I want some horrid torquesteery monsters


This is primarily a styling challenge, though engineering will play a part in determining which tier a car sits at.

FWD cars just don’t fit the theme of the challenge, especially considering the contestants’ (or rather players’) reliance on powerslides to rack up points, and the minimum power limit is kind of at odds with FWD anyway.

Speaking of which, damn, I forgot to add priorities… One sec.


since among the inspirations i’m seeing normal, current day sports cars alongside futuristic concepts, what’s the preference? is it preferable to build something concept-y or something more grounded?
Edit: i’m also not seeing a maximum year, is it ok to go to 2020 everywhere?


In terms of production cars versus concepts, I don’t specifically prefer one or the other; I just chose the ones that were more in line with the intended styling theme. You can thus go either direction, as long as the aggressiveness is there.

By all means.


Any restrictions on Advanced Trim Settings?


This feels very much like a rerun of CSC 7, which I am absolutely here for. Looking forward to this one.


To reinforce the Split/Second connection further, your use of Elite as a manufacturer name references the fictional carmaker of the same name from that game.

Aagh, something else I forgot. It seems I was so excited to get this out that some things were bound to go unnoticed, so thank goodness for the rule review period.

Is that really necessary?


Fine, I’ll just limit it to 200 mm.


is tyre diameter allowed?




Of course, I won’t hesitate to bin anything that looks like it’s riding on monster truck tires on aesthetics grounds, so do try to keep it within reason for the car’s suspension setup.


Could we allow Wheel Diameter as well? I would like to have bigger wheels but my car will not let me go past 18s without the tire’s blowing up.

Sure. I was a little afraid of cheese, but then I remembered that I can just yeet any suspiciously fast cars that don’t look the part (and I won’t be looking that closely at general stats like sportiness anyways).


If no one has any objections to the rules, I think I’ll open the round for submissions at around 00:00 EST (in 8 hours).


ooh, this looks fun. Question tho, if we make an Elite car, does it have to have the name of the racer in it or can we just do whatever? Been a big fan of Split Second, even if I only got halfway through


No Elite Racer names are needed, nor even is the signature black-and-bluish-grey two-tone (well, I’ll require the black, but the secondary colour is up to you). Any Elite vehicle should, of course, reflect its mid- to high-tier status with good performance.


I’ll try my best lol, but I’m pretty new to the game so no promises. Colour scheme is probably gonna be similar tho, its super good looking


The Reflex development team is giving all outsourced studios 3 weeks to come up with suitable designs.
A link to the deadline can be found in the post at the top.
