NEW CODES & NEW CARS UPDATE! | Junk Mechanics ROBLOX (September 13, 2026)
Table of Contents

The latest content drop has finally arrived, and players are scrambling to get their hands on the most expensive engine in the game's history. This junk mechanics update introduces a wealth of features that transform the car-building experience, ranging from high-fidelity engine remodels to new ways to earn cash through speed traps and daily challenges. If you have been waiting for a reason to dive back into the junkyard, the sheer scale of this junk mechanics update provides the perfect opportunity to build your dream machine.

Why does this specific patch matter so much to the community? Beyond the surface-level additions, the developers have fundamentally rebalanced how performance parts like turbos function, making high-end builds feel significantly more responsive. Whether you are a veteran flipper looking for the next big profit or a car enthusiast wanting to hear the roar of a V10, this update has something for everyone.

The V10 Revolution: Power at a Premium Price

The centerpiece of the latest junk mechanics update is undoubtedly the introduction of the V10 engine. For a long time, the V8 was the king of the shop, but the V10 now takes the throne as the most powerful and expensive block available at Car Zone. Community reports indicate that this engine isn't just a status symbol; it provides a distinct power curve that rewards high-speed stability and raw acceleration.

However, power comes at a steep price. To fully assemble a V10, you will need a significant bankroll. Below is a breakdown of the costs associated with the new V10 components found at the Car Zone shop.

Component Price (Cash) Importance
V10 Engine Block 220,000 Core component, extremely expensive
Cylinder Head 80,000 Essential for engine completion
Turbos 55,000 Provides massive performance boost
Exhaust Manifold 25,000 Required for airflow
Intake Manifold 20,000 Required for fuel/air mixing

Currently, the V10 is not a universal fit. According to the developers, they are testing the engine's impact on game balance before rolling out wider support. As of now, you can only swap this powerhouse into a select few vehicles.

V10 Compatible Vehicles:

  • Dodge Viper (The natural home for a V10)
  • Audi R8
  • Lexus LFA
  • Ferrari Testarossa (New addition)
  • CLK (Referred to as the "LT" in some menus)

New Vehicles: From Classics to Modern Icons

No junk mechanics update would be complete without fresh metal to work on. This patch introduces three distinct vehicles that cater to different tastes, from 80s nostalgia to modern track-focused precision. A notable change in this update is the shift toward "fictionalized" branding. For example, the new GT3RS is branded as the "Ferdinand," featuring clear tail lights and slightly modified headlight designs to fit the game's aesthetic.

The Ferrari Testarossa is perhaps the most exciting addition for fans of classic styling. It features fully functional pop-up headlights, which has been a highly requested feature from the community.

Vehicle Name Real-Life Inspiration Estimated Value/Cost Key Feature
Ferdinand GT3RS Porsche 911 GT3RS 2,500,000 Fictional badges, clear lights
Mustang GT500 Ford Shelby GT500 700,000 (Sell Price) Massive body profile
Ferrari Testarossa Ferrari Testarossa Varies (Auction) Working pop-up headlights

Players should note that some of these cars are currently exclusive to the auction system. You will need to keep a close eye on the Premium and Cash auctions to snag these rare finds. Community reports suggest that the Testarossa, in particular, sounds incredible when paired with the new V10 engine, creating one of the most immersive driving experiences in the game to date.

Customization Overhaul: Horns, Underglow, and Tints

While performance is key, looking good is just as important. The junk mechanics update has expanded the customization shop significantly. For the first time, players can now add underglow to their vehicles. While some veteran players have jokingly labeled this as "ricey," it offers a new layer of personalization for night-time cruising.

In addition to visual flair, the update introduces auditory customization. You can now swap out your standard car horn for various alternatives. The customization shop also allows for deeper license plate editing, enabling players to use special characters like stars and hearts to make their builds stand out.

New Customization Options:

  • Glass Tinting: Adjust the opacity and color of your windows.
  • Underglow: Multiple color options to light up the road beneath you.
  • Plate Customization: Add symbols and custom text (no longer restricted to creators).
  • Horn Variations: Choose from three distinct sounds, ranging from standard to unique tones.

Earning Rewards: Tasks and Speed Traps

To help players afford the massive 220,000 price tag of the V10 block, the developers have introduced a Task System. This system provides Daily and Weekly challenges that reward players with cash, premium keys, and even free cars. According to player experience, these tasks auto-collect, meaning you don't have to manually claim your rewards after completing a challenge.

The introduction of Speed Traps across the map also adds a new gameplay loop. Passing through these traps at high speeds earns you money and "stars" based on your performance. This is a great way to test your new builds while earning a passive income.

Task Type Typical Reward Frequency
Daily Tasks Cash & Experience Every 24 Hours
Weekly Tasks Premium Auction Keys Every 7 Days
Speed Traps Immediate Cash Repeatable

Community members have noted that completing these tasks sometimes results in a "mystery car" being added to your inventory. While this is a great way to get a Honda Civic or other starter cars, some players have expressed a desire for an "auto-sell" feature to keep their inventories clean.

Engine Remodels and Performance Buffs

A subtle but important part of this junk mechanics update is the visual rework of existing assets. The V8 engine has received a complete remodel, making it look far more realistic and detailed compared to the older versions. While the other engines (like the I4 or V6) haven't been updated yet, the developers have signaled that more remodels are on the way.

On the performance side, turbos have received a long-awaited buff. Previously, many players felt that adding a turbo didn't provide enough of a "kick" for the cost. In this update, the turbo logic has been rebalanced to offer a more noticeable boost in top speed and acceleration. If you felt your McLaren or supercar was sluggish before, try taking it for a spin now—you will likely notice a significant difference in how it handles the straightaways.

For those who enjoy creating content or taking screenshots of their builds, the new "Free Cam Tilting" feature is a game-changer. By allowing the camera to tilt, players can capture more dynamic, cinematic angles of their cars, which is perfect for sharing on social media or community Discord servers.

Expert Tips for the New Update

To make the most of the new content, you should prioritize your spending. Don't rush into buying a V10 block unless you already have a compatible car like the Viper or LFA. Instead, focus on completing your Daily Tasks to build up a reserve of Premium Auction Keys. These keys are the only way to access the high-end auctions where the rarest cars appear.

If you are looking for more information on the base game mechanics or want to see the official patch notes, you can visit the official Junk Mechanics page on Roblox. Staying connected with the community on Discord is also highly recommended, as the developers frequently ask for feedback on which cars should receive V10 support next.

Remember to check the speed traps frequently. Even if you aren't trying to set a record, the small cash injections from passing through them add up over time, helping you pay for those expensive V10 intake manifolds and exhaust systems.
