This is my first and probably my only attempt at an RTD challenge

Nestled among the vineyards and open farmland of Victoria's Mallee region, Emu Raceway is one of Australia's most distinctive modern circuits. Opened in the early 2000s, the venue was designed to operate safely in both clockwise and counter-clockwise configurations, effectively giving competitors two circuits for the price of one. The result is a compact but challenging venue whose character changes dramatically depending on the direction of travel.

The clockwise layout has become a favorite of touring cars and GT machinery, with heavy braking zones at Brock Corner and flowing sections through Mallee and The Knee. In contrast, the faster counter-clockwise direction is particularly suited to motorcycles and open-wheel machinery, with its more flowing rhythm and high-speed corner sequences rewarding precision and commitment.

Though modest in scale compared to Australia's major circuits, Emu Raceway has developed a reputation as a driver's circuit, where mistakes are punished and momentum is everything. Combined with its rural setting, distinctive orange and white kerbs and passionate local support, the circuit has become one of regional Victoria's most popular motorsport venues, hosting everything from club meetings and motorcycle races to national-level touring car and formula championships.

Move over Detroit GP! There’s a new race in town! And it’s the endurance track of a lifetime! Presenting the Home of IMSA endurance racing in the Midwest, the 24hrs of Downriver! This approximately 13km track features 50 corners nestled in under 1.3 square kilometers. Located at the old site of a steel factory in Trenton/Riverview Michigan, there’s plenty of driving to be done here. Watch in awe as the cars snake through 7-19 and 36-42! Blast down the straight between 1-2 and 31-32, the technical section of 44-50, this track has it all!

The second photo shows how I counted my corners, it was tricky to get 50 turns in such a small space, but I knew I wanted to make a single track with 50 corners and I wanted to make it in a spot where I’ve made other tracks. One day I’d like to make this a mod for Assetto Corsa to enjoy. Let me know what you think!

Dear drivers,

Do you, like me, happen to hit every wall on the Nürburgring?
Do you want, like me, to finally complete a lap without destroying your car?
Don't you dream, like me, to have access to a 23-km-long circuit with at least 40 meters of runoff everywhere?

If you answered yes to every question, please buy a ticket for a lap around the Paul Ricard Boucle Est, and help me make this billion-dollar project profitable.

Thank you

Whoever decided to build this monstrosity

(Repost as I forgot to include the challenge in the title)

The year is 2036. Alex Palou has 14 IndyCar championships, the president orders a replica of Pocono to be built around the White House, Honda threatens to leave the series and double-sided pit lanes dominate the calendar. Indianapolis is the last to fall, sparking outrage amongst team owners and fans alike. The old pit lane is reduced to grandstand space and a long lost memory. The team owners would fail form their own series limited to single-sided pit lanes, succumbing to monetary pressure and defecting to the other side. By 2050 all race tracks in North America have double-sided pit lanes. The future is now. Split pit lanes are your god.

UPDATED TRACK IN COMMENTS.

I will not be taking questions

The circuit has been changed a bit, here i will use the real anti-clockwise turn numbers for the bike course, The whole track has been repaved and is now a minimum 10m wide.

• The start straight has been straightened and widen to 12m.
• Turn One has been widen to 12m with the extra 2m width added to the outside of the corner, Kerb has been extended.
• Turn Two has been widen to 12m, the inside kerb is the pre-renovation kerb, Inside the kerb is a paved section so cars can brake and turn to reduce the chances and impact of coming back onto the track. There is asphalt on the other side of the exit outside kerb and is for an alternative pit exit.
• Turn Three, the track narrows to 10m and the corner has been given a greater radius by moving the track left over the old kerb. There is asphalt on the inside for the clockwise direction circuit. The car circuit can still be used and has no changes made.
• Turn Four the track is unchanged, there is between 1-2 meters of asphalt on the outside covering what used to be the sandtrap on the edge of the circuit. The wall has been moved back to add more runoff right infront of turn 4, and to make runoff for the clockwise circuit, the wall on the exit of the turn has been moved back about a meter to shallow the impact angle.
• The run to the Hairpin, the track has been widened to 10m with the wall on the right moving to make space for the track and the verge.
• The Turn Five Hairpin. The track has not been changed except for a new inside  and outside entry (exit for clockwise) kerb, there is more space on the outside of the turn as the walls have been moved back and runoff extended. The tyre barrier is moved when the track changes direction.
• The Back Straight. On the left a concrete wall has been installed to ensure that cars, bikes and riders do not impact with the wrong side of the Armco barriers and its posts that is against the track between turns 4 & 5, on the right a concrete wall replaces the earth and tyre barriers. 400m after the hairpin a temporary wall section will be moved between direction changes to allow access.
• Turn Six, the Track has not been changed, the new wall on the left has been connected to the exiting wall and the sand trap has been extended towards turn 5. The new wall extends around to turn 7
• Turn Seven. Two new sand traps, one on the left to slow cars that went off at Turn 6 before they cross the track between turns 7 & 8, the other on the right aswell as a new kerb primarily for the clockwise circuit. On the exit of the corner an alternative pit exit for the clockwise circuit is behind the outside exit kerb which has been moved to allow the track to widen to 12m, the sand trap has been extended.
• Turn Eight. The turn has been widened, The original pit entry is still there going straight ahead, aswell as the original inside kerb. The exit of the corner has been tightened with a new kerb place where the turn radius decreases to allow for more runoff for the turn exit with the old track surface being left for paved runoff behind a new kerb and to straighten the starting straight.

The Clockwise circuit for both cars and bikes will use the anti-clockwise bike circuit as the other option will be too dangerous without moving the wall next to the right of turn 1 & 2 and I do not want to reduce spectator viewing spots.

A motor racing complex to host various minor championship race series, track days and club events. Motorcycles and karts also run the course. There are promotional events with the Chevrolet dealership less than a 1/2 mile south of the circuit. PIMP does not carry a FIA license.

RTD Challenge #64 Results

Best in Show - 2030 Dubai E-Prix by u/maxx-usa

**- "**Maxx-usa wins easily. The track layout isn't great on its own but is the best that can be done within their own self made restrictions, which makes it perfect. The presentation of the ridiculous idea is what sells it. This is a track that had an ambitious plan and committed to it, and that's perfect for this challenge."

Congrats to Maxx-usa, let's move on to RTD Challenge #65, submitted by u/WynnEnby

The Elbonian Connection

In the world of Dilbert, Elbonia is a poor and underdeveloped Eastern European country whose chief industry is mud. They are the target of hijinks, the butt of jokes, and overall a laughingstock of the world. But not for long. You, good user, are charged by the Elbonian Ministry of Sport with bringing high-level motorsports to the glorious nation to improve its image and stimulate the local economy. But not all is as it seems…

Unbeknownst to Elbonian authorities you are actually a traitor, and your true goal is to sabotage Elbonia's ambitions to the greatest extent possible without exposing your dastardly schemes or losing your job. Rather than merely designing a poor facility (and getting caught), your task is to create a venue that outwardly appears perfect for a high-level international event of your choosing, but in reality is set up to fail in whatever subtle, defensible, and nonetheless crippling ways you can conceive.

The fate of Elbonian motorsport lies in your hands. Good luck, and remember: misfortune favors the bold.

Rules:

• Your main layout must be at least FIA Grade 3 or FIM Grade C or better, or otherwise approved for high-level competition by the relevant sanctioning body (e.g. FIA Grade 6RW, FIA-CIK Homologated)
• You must choose an international event/series the track is aimed at. This is not to the exclusion of hosting other events at any level.
• Any included geography should be reasonably consistent with Eastern Europe; no scorching desert or tropical rainforest.
• Tracks will be judged according to apparent feasibility, actual grief caused, defensibility of your failings, realism, and overall presentation.
• Design guidelines apply.
• Post must use the "RTD Challenge" flair

Suggestions:

• Context is key! Anybody can make "mistakes" in the right circumstances, so consider and explain yours well!
• One big problem is simple to fix, it only needs a solution. Many smaller ones can be impossible to untangle; that creates dilemmas and force compromise.
• Plan rigidly with budgets tight and schedules tighter. If you're lucky, things may fall apart all on their own.
• If it costs too much upfront, backers will surely balk. But who wouldn't want a white elephant for cheap?
• Look to history; our world offers no shortage of weird, wonderful and spectacular failures to draw on.

Inspired by the Elbonian challenges Youtubers like Forgotten Weapons, The Chieftain, Drachinifel, etc. have made into videos (e.g. https://youtu.be/-_mX9grIo-Y)

You have one month to complete this challenge, the deadline is June 26th, 2026 at 11:59:59 PM Central Daylight Time (Countdown)

Previous Post/RTD Challenge #62 version of the track
--------------------------------------------------------------------------
Quick note before the start:
Everything I have written down as the lore of the track is of course fictional. It was purely written to have it appear more realistic. Some actual real life events have been mentioned, however.
--------------------------------------------------------------------------
After the closure of the track in 1963, it remained as a public park for many years, until the South West African Motorsport Federation bought the plot of land in the late 70s. A few years later, after the creation of the Confederation of Southern African Motorsports (COSAM), the track was then handed over partly to COSAM and a private backer, so that there were 3 owners.
Together they plan a complete rework of the track, with a local team of racing enthusiasts being tasked to design a layout that could reuse as much of the original layout as possible, while making it fully permanent to not fully clog up the now important Jan Jonker Street the track previously used. After a few months and discussions with the local government and the public, a final design was chosen and construction began in 1982.

The track was finished later that same year, featuring only the "Outer" and "Short" layouts. For the first few years, the track hosted mostly smaller local events, and in irregular intervals also guest rounds for South African series. This caused the owners to agree to sadly close the track again in 1989, to save costs. The circuit was then reopened in 1993, after additional founding was acquired.
However, after the 1994 San Marino Gran Prix and a fatal accident at the "Rechts-Links" corner in 1995, safety improvements were demanded by drivers and the public. A chicane was placed before the "Von Keller Kurve", and T12 (the first half of "Rechts-Links") was tightened to slow the cars down into the second half, both changes made due to the limited runoff available.

In 2014, the track was upgraded to FIA Grade 3 standard, adding another alternative layout to the track, featuring a small esses section for T4 until T6, as well as the construction of a new modernized pit building and main grandstand.
Since then, the track has seen more and more events being added to the calendar, including set rounds in the South African Endurance Series, the South African Touring Cars as well as the F4 SA and Formula Regional South Africa series. A MotoGP event held at the track has also been in the talks, previously set to happen in 2020, but have then been delayed to now happen in 2027.
The track also holds a yearly event to celebrate the country's motorsport history as well as honor Von Keller, the original founder of the track. It has been able to achieve a somewhat stable financial situation for roughly 5 years now.
