EVO Tuning and EVO Viewer Guide
What EVO Tuning Is
EVO tuning is an additional level of customization for selected cars in Asphalt Legends, available only for cars with Gold status. Gold means that the car is fully upgraded: all stars have been obtained, all upgrades have been applied, and all parts have been installed.
Once Gold status is reached, standard progression is exhausted, and EVO becomes the only way to further fine-tune the car for a specific driving style or track. Unlike classic upgrades, EVO does not simply increase stats - it allows the player to choose the direction in which the car develops.
Each car with EVO support has 24 parts divided into 5 groups: engine, transmission, nitro, nitro gain, and special pack. The number of parts in each group varies - for example, 4 engine parts, 5 transmissions, 6 nitro parts, and so on. Each group also includes a stock part - a zero-level part meaning no EVO modification in that category. Only one part from each group can be active at any given time.
Parts are obtained through EVO tickets unique to each car. The first four tickets are free, while the rest can be purchased with tokens or earned through special events and Legend or Ultimate passes. Installing and swapping parts is free and available at any time.
What EVO Viewer Is
The EVO Viewer is a third-party tool developed independently from the game. Its purpose is to allow players to test all possible combinations of already available parts and evaluate the result in advance, without needing to own or install those parts in-game.
The problem it solves is simple: once all parts are obtained, the number of possible combinations becomes significant, while the in-game interface does not allow proper evaluation of each part’s impact without physically installing it. The Viewer allows players to freely assemble any setup, view final stats, acceleration graphs, and the resulting car archetype - all without spending any in-game resources.
The Viewer is also useful for players who have not yet reached Gold status on a specific car but want to understand in advance what results EVO tuning can provide.
What stats are show
Stat Bars - What Is Hidden Behind Them
The familiar game interface displays car characteristics as bars: top speed, acceleration, handling, nitro, and nitro gain. At first glance, everything seems straightforward - a part adds value to a bar, and the bar increases. However, each of these bars is actually a combined value aggregating several independent parameters. The EVO interface allows us to look behind the scenes and better understand what these bars really represent.
Acceleration is the clearest example. The acceleration bar reflects an overall value that includes ground acceleration, air acceleration, and the way torque is distributed across the speed range. A transmission part may increase the total bar value while simultaneously shifting torque toward higher speeds - resulting in slower launches despite the formally increased stat. Without an acceleration graph, this effect is almost impossible to notice.
The nitro and nitro gain bars work similarly - each hides up to 12 independent values that parts can affect in different ways and combinations.
Air Speed - Difference Between Interface and Reality
The maximum air speed stat deserves special attention. The in-game EVO interface displays this value incorrectly because it does not account for the speed added by nitro. Since the game operates using internal units (units per second) and converts them into km/h through a piecewise linear function, the discrepancy between the interface and actual in-race values may reach 15–25 km/h.
The EVO Viewer accounts for the nitro component when calculating air speed and displays values corresponding to the actual behavior of the car in races, with an error margin of ±3 km/h.
Acceleration Graphs
The time required to reach top speed is only a single number and does not describe the nature of acceleration. Two transmission parts may show the same total acceleration time while behaving completely differently: one provides an aggressive launch and reaches high speeds quickly, while the other delivers a smoother and more even acceleration curve. Depending on the track, this difference may be crucial.
The EVO Viewer displays a complete acceleration graph (time/speed) for the current part setup, showing dynamics across the entire range - from launch to top speed. The time to reach maximum speed on the graph matches real behavior with an accuracy of ±0.03 seconds.
Car Archetype
What an Archetype Is
An archetype is an official car stat within the EVO system that determines its weight category. The archetype is based on the combined weight of all installed EVO parts and changes automatically when the setup changes.
There are four archetypes corresponding to different weight categories. Each car has its own archetype weight ranges. For example, the archetypes for the Chevrolet Camaro LT are:
Archytype
Weight
Light
up to 1370
Neutral
1371-1760
Heavy
1761-2250
Overload
2251 and above
Transitions between archetypes are sharp and discrete - crossing a threshold immediately changes the category and all associated effects.
How Archetypes Affect the Car
Each archetype provides fixed bonuses and penalties to two measurable characteristics - handling and car rank. In addition, archetypes directly affect the physical behavior of the car in races: drift radius, turning radius, and speed loss during cornering and drifting.
The general pattern is simple: the heavier the archetype, the wider the turning radius and the more speed the car loses while drifting. A light archetype provides sharper handling and smaller losses, while an overloaded archetype does the opposite. This behavior cannot be expressed through universal numerical values because it depends on the physical model of a specific car.
Archetype as a Build Variable
In practice, archetype is not merely a side effect of part selection but an intentional variable when creating a build. Heavy and overloaded parts provide larger stat increases but push the car toward worse handling. Light parts preserve or improve handling but offer lower raw stat values.
The optimal archetype depends on the specific car, track, and driving style. A car with higher stats but a heavy archetype may lose on a technical track full of corners against a lighter build with lower paper stats. The EVO Viewer displays the current archetype and all associated bonuses and penalties in real time while changing parts.
Parts Groups
Engine
Engine parts affect the car’s maximum ground speed. Since maximum air speed is derived from ground speed, changing an engine part affects both values simultaneously.
This is the most straightforward group: parts mainly differ by weight and the amount of top speed increase they provide. The decision here is primarily based on whether the speed gain justifies shifting the archetype toward a heavier category.
Transmission
Transmission parts affect the nature and speed of acceleration. This is the least obvious category because the final acceleration time to top speed does not fully describe the car’s behavior.
Two parts of the same type may show similar total acceleration times while differing dramatically in torque distribution:
one part provides an aggressive launch with rapid acceleration at low speeds and a flatter approach toward top speed
another performs mainly in the upper speed range - launches are slower, but the car accelerates and maintains speed more effectively at high speeds
On short tracks with frequent speed drops, the first option is preferable. On fast tracks with long straights, the second may perform better. This is why the EVO Viewer includes an acceleration graph - it displays the full acceleration curve from launch to top speed rather than just the final time.
Nitro
Nitro parts affect the characteristics of the four nitro types available in the game:
-
Normal Nitro (yellow)
-
Explosive Nitro (orange)
-
Perfect Nitro (blue)
-
Shockwave (purple)
Each of the four nitro types has three independent parameters: acceleration boost, speed boost, and duration with a full nitro bar. Altogether, this group covers 12 values.
A nitro part may affect only one parameter or several at once in different combinations and proportions. For example, one part may only increase the speed boost of blast nitro, another may increase the duration of all four nitro types simultaneously, while a third may affect multiple parameters across several nitro types.
This makes nitro one of the most variable groups: the final effectiveness of a part strongly depends on which nitro types are actively used in a particular driving style and on a particular track.
Nitro Gain
Nitro gain parts affect the speed at which the nitro bar fills from different sources. There are 12 such sources in the game, each representing an independent parameter - examples include nitro gained from bottles, stunts, drifting, and other in-game actions.
The logic is similar to the nitro group: a part may affect one source or several in different combinations. One part may significantly increase nitro gain from drifting while leaving all other sources unchanged. Another may provide moderate increases across most sources.
The choice of part in this category directly depends on driving style: a player who relies heavily on drifting and a player focused on stunts will experience different practical effects from the same part.
Special Pack
The Special Pack is the most diverse group. Unlike the other categories, its parts are not united by a single mechanic: every part serves its own purpose, and the affected parameters vary significantly between parts. As with all other categories, every Special Pack part affects car weight and rank - all other effects are individual.
Based on their effects, Special Pack parts can be divided into several subtypes.
-
Lightweight Parts
Their primary purpose is reducing the total weight of the setup, allowing the archetype to shift toward a lighter category without replacing parts in other groups. Some lightweight parts additionally provide small increases to top speed and rank, though this is secondary. They are especially useful when the build weight is close to an archetype threshold.
-
Turbo
Turbo parts increase maximum ground speed. Since air speed is derived from ground speed, both values are affected. Mechanically, turbo parts are similar to engine parts, but they belong to a separate category and can be combined independently, allowing both speed sources to stack.
-
Aero Packs
These increase maximum air speed and/or air acceleration without affecting ground speed or acceleration. They are useful on tracks with long jumps and ramps where the car spends significant time airborne.
-
Tires
This is the most ambiguous subtype. Tires increase maximum ground speed (and therefore air speed), but their key feature lies elsewhere: depending on the specific tire, they may either improve handling and reduce cornering speed loss or worsen handling in exchange for higher speed performance. This is the only subtype within the Special Pack category capable of directly affecting cornering behavior aside from archetypes.
How to Read the Viewer
The Viewer is organized vertically and consists of four sequential sections.
-
Header
The upper section of the page contains general information about the car. Here you can find the car name, image, and reference data: the number of blueprints required for each star, the number of parts needed to reach Gold, and the purchase/sale price of EVO tickets. This information is useful for estimating how resource-intensive it will be to fully upgrade a specific car and obtain a complete EVO part collection.
-
Category Selection Row
Five buttons switch between active part categories: engine, transmission, nitro, nitro gain, and special pack. Only one category is displayed at a time.
-
Category Block
The main working area of the Viewer, divided into two sections. On PC and tablet they are positioned side by side; on mobile devices they are stacked vertically.
-
Part Selection Block
A scrollable list of all available parts in the selected category, including stock. The currently installed part and the part selected for preview are visually highlighted. Next to the list, the selected part’s description and key characteristics relative to stock are displayed, allowing the player to evaluate the part before installing it.
-
Stats Block
Displays the consequences of the current choice within the context of the entire build. This block always includes the weight bar with the current archetype, car rank, and the affected base stat bars. Additional content depends on the active category:
Engine / Transmission - acceleration graph displaying the complete speed curve from launch to top speed
Nitro - four stat triangles, one for each nitro type (normal, explosive, perfect, shockwave); each vertex corresponds to one of the three parameters: acceleration boost, speed boost, and duration
Nitro Gain - a table containing values for all 12 nitro gain sources
Special Pack - secondary stats such as air speed, air acceleration, and steering speed lost
-
-
Final Stats Block
The lower section of the page is always accessible regardless of the active category. It displays the currently installed parts in all five categories and compact summary values for the entire build. This serves as the final verification point, allowing the player to evaluate the build as a whole without switching between categories.
Accuracy and Limitations
-
What the Viewer Displays Accurately
All characteristics read directly from game data - maximum ground speed, nitro parameters, nitro gain values, part weights, archetype, and rank - are displayed without error.
-
Air Speed
Maximum air speed is calculated using known formulas based on available game data. The displayed value matches real in-race behavior with an error margin of ±3 km/h.
-
Acceleration Graph
The graph is built using known data and correctly reflects acceleration dynamics - the shape of the curve and the relationship between parts are displayed accurately. The time to reach top speed matches real behavior with an error margin of ±0.03 seconds.
At the same time, the graph is a calculated model rather than a recording of an actual race. Absolute values on individual sections of the curve may differ slightly from real car behavior, but the precision is sufficient for comparing parts against one another.
FAQ
-
Q: Why does the game show a much lower air speed value than the EVO Viewer?
A: The game contains an error in the air speed calculation formula. The EVO Viewer uses a corrected approximate formula instead. This issue only affects the EVO interface itself - during races, actual air speed will be close to the value displayed in the Viewer.
-
Q: A Special Pack part increased acceleration, but the car did not become faster. Why?
A: You installed a part that increases air acceleration. Due to the nature of these parts, they add value to the overall acceleration bar while affecting only air acceleration and not ground acceleration.
-
Q: I found an error or inaccuracy in the data.
A: You can report any inaccuracies on our Discord server in the reports section.
-
Q: An air speed part says it increases speed by 16%, but the real value is lower. Why?
A: This percentage is applied to the internal measurement units used by the game engine. These units are then converted into km/h using a piecewise linear function for display in the game interface, which is why the resulting km/h increase differs from the displayed percentage.
