View source for Upgrade

An '''Upgrade''' is a permanent car performance upgrade in the ''Asphalt'' series, which increases the car's rank. Upgrades can't be undone, so downgrading a vehicle isn't possible by conventional means. Upgrades differ from Boosters by not being time-related and from [[Pro Kit]]s by not requiring parts, but only Credits or Tokens to apply. Also, in contrast to Pro Kit upgrades, all five upgrade levels (ten in the case of most motorcycles) are available for every car of the game.

There are four categories for (standard) upgrades:
# Acceleration - depicted as an engine block
# Top Speed - depicted as a turbocharger
# Handling - depicted as a brake caliper
# Nitro - depicted as a nitrous tank
Each category contains five upgrade levels above the basic (zero) level, and each upgrade made adds to the performance of the car and increases the rank of the car.
Rank (when the car is either stock, MAX, PRO, or MAX+PRO) is calculated as: (34.7-SQRT((34180.823-92.692*Nitro)/Top Speed+1014.173))*1000 - This is assuming the unit system is set to metric.
The maxed out acceleration stat is <sup>11</sup>/<sub>15</sub> (73.33%) of the stock acceleration stat; the maxed out handling stat is the stock handling stat + 0.05 Gs; and the maxed out nitro stat is usually the stock nitro stat multiplied by 1.5. The maxed out top speed stat is a certain number higher than the stock top speed stat. Examples:
* Acceleration: 2.20 sec &rarr; 1.69 sec
* Handling: 1.300 Gs &rarr; 1.350 Gs
* Nitro: 16.86 mph (27.14 km/h) &rarr; 25.29 mph (40.71 km/h)
Example from the [[Jaguar F-TYPE Project 7]]:
* Rank: 1215.28 (1215) &rarr; 1438.98 (1439)
* Acceleration: 3.90 sec &rarr; 2.86 sec
* Top Speed: 183.72 mph (295.79 km/h) &rarr; 205.01 mph (330.07 km/h)
* Handling: 1.200 Gs &rarr; 1.250 Gs
* Nitro: 16.86 mph (27.14 km/h) &rarr; 25.29 mph (40.71 km/h)

The [[2019 Holiday Update]] introduced the '''Ultimate''' status, indicated by a gold {{Ultimate a8}} icon. Ultimate vehicles are already fully upgraded as if they were MAX or PRO. They cannot be upgraded any further. These include the following:

The [[Gangstar Season Update]] introduced the '''Direct Upgrade''', an item that applies an upgrade level without the use of {{a8fusioncoins|Fusion Coins}} or kit cards.
* Existing vehicle-specific upgrades are converted to Direct Upgrade of the corresponding class of the vehicle
* There are 5 types of Direct Upgrade:
** {{Direct Upgrade - Class D a8}}: for upgrading Class D Vehicles
** {{Direct Upgrade - Class C a8}}: for upgrading Class C Vehicles
** {{Direct Upgrade - Class B a8}}: for upgrading Class B Vehicles
** {{Direct Upgrade - Class A a8}}: for upgrading Class A Vehicles
** {{Direct Upgrade - Class S a8}}: for upgrading Class S Vehicles
* As the Direct Upgrade covers the space of the Ad Upgrade, in order to upgrade a car by watching ads, exiting Direct Upgrade(s) must be used up

As of the Gangstar Season Update, all cars are now {{Pro a8}} only, whereas all bikes are now {{Max a8}} only. 

=== Upgrade Prices ===
The upgrade prices of each level can be found from the car pages. [[Vehicles of Asphalt 8]] page features a summary table of costs to max out the vehicles.
The price of the upgrades rises on every level and it also costs more to upgrade a higher end or more recently added car. The original cars of the game with blue and white license plates and all pre-[[Fuel Events Update]] cars (until after the introduction of [[SSC Tuatara]] around April 2014, which was the first car with higher upgrade costs) can be upgraded to MAX level with considerably less amount of Credits compared to the cars that were introduced in updates after the Fuel Events Update. The upgrade costs of the cars introduced in the Fuel Events Update fall mostly between these two ends. The [[SSC Tuatara]] is the first car to have higher upgrade costs.
This radical shift upwards in the upgrade (and purchase) costs of the cars has led to significant discrepancies to the relation between the upgrade costs and performance gains when upgrading a vehicle. It is notable though that while introducing this new era of high prices, it's mainly done by bringing in new cars to the game - the upgrade (and purchase) costs of the vehicles that are already found in the game aren't drastically modified. However, the highest cost for upgrading a Class D car drastically jumped in the [[Tenerife Update]] with the [[BMW M3 Sedan]], which costs {{A8Credits|2,059,330}}.
Since [[Lunar New Year Update|v2.3]], new cars added to the game can be upgraded either with Credits or Tokens. In the [[Elite Cars Update]] (v2.4.0), two new cars require Tokens for their upgrades: the [[BMW 3.0 CSL Hommage]] and [[Mosler Super GT]].
During the [[Munich Update]], several recently released vehicles had their credit prices removed for some upgrades and were tokens only until it was reverted on October 31, 2017, due to negative reception from the community.
In nearly every update released in 2018, some event-based cars require Tokens for some upgrades, especially the [[Lamborghini Centenario LP 770-4]], which has every level 4 and 5 upgrades require a total of {{A8tokens|13,950}}.
In the [[2019 Spring Update]], the upgrade prices for many vehicles were changed.

=== Free upgrades ===
==== v5.0 ====
The [[Fifteenth Anniversary Update]] made all free upgrades fully saleable.
* Class-specific upgrade cannot be obtained any longer, except for the {{Class A Upgrade a8}} and {{Class S Upgrade a8}} which are granted as league rewards in [[Multiplayer]] if the player already owns the awarded vehicle.
* Vehicle-specific upgrades are sometimes offered for real money.
{| class="table-a8" style="float:right; margin:0 0 1em 1em;"
! Upgrade || Value
|-
| {{Class D Upgrade a8}}
| style="text-align:right;" | {{currency|type={{Class D Upgrade a8|#value currency}}|{{Class D Upgrade a8|#value}}}}

|}
The sale value of vehicle-specific upgrades was reduced by factor 10; they now have the same value as a class-specific upgrade of the vehicle's reassigned class. Examples:
* A free upgrade for the [[Hyundai i30 N]] has been reduced from {{a8fucs|30000}} to {{a8fucs|3000}} (both Class D).
* A free upgrade for the [[BMW 3.0 CSL Hommage]] has been reduced from {{a8fucs|120000}} (Class A) to {{a8fucs|15000}} (Class S).
{{clear}}
==== v4.7 ====
Free upgrades could be earned as rewards by finishing certain [[Collection (Asphalt 8)|collections]] or in certain [[Research & Development|R&amp;Ds]]. Free upgrades from collections were class-specific while free upgrades from R&Ds were vehicle-specific.
The [[2019 Holiday Update]] turned all free upgrades into [[inventory]] items, but only vehicle-specific upgrades could be sold for {{a8fusioncoins|Fusion Coins}} if the corresponding vehicle was at {{max a8}} level.

Examples:
* Class D
** [[Hyundai i30 N]]: {{a8fusioncoins|30000}}
* Class C
** [[Nissan 370Z Special Edition]]: {{a8fusioncoins|60000}}
** [[Yamaha YZF-R6]]: {{a8fusioncoins|60000}}
* Class B
** [[Ducati Monster 1200]]:  {{a8fusioncoins|90000}}
* Class A
** [[BMW 3.0 CSL Hommage]]: {{a8fusioncoins|120000}}
* Class S
** [[Arash AF10]]: {{a8fusioncoins|150000}}
Spare vehicle-specific upgrades could not be fused separately, so if players had three Hommage upgrades, they could only fuse all three together.
Formerly, free upgrades (Class D & C) were also one of the alternating prizes in Multiplayer, when having a seven game (Class D upgrade) or nine game (Class C upgrade) winning streak (finishing in the top 3 in seven/nine Multiplayer games in succession). The other alternative prize for a 7 game winning streak was {{A8Credits|5,000}}. For the 9 game winning streak also a [[Nitro Starter]] or {{A8Credits|7,500}} could be earned as a reward. [[Mastery]] also awarded Free Upgrades prior to the [[Fast Lane Update]].
"Each free upgrade is linked to a class of cars (D, C, B, A, or S). When a player owns a free upgrade, the next purchase of an upgrade for a car in that class is free. The player cannot choose when they spend the free upgrade. It is always the first purchase they make after receiving it."

=== How to upgrade a car? ===
# Select a car you wish to improve
# Tuning &rarr; Upgrade (the available upgrades are shown) &rarr; Tap on the purchase icon of the desired category. If the upgrade costs only Credits or Tokens, tap on the icon. Otherwise, if the upgrade is ''either'' Credits or Tokens, tap on one of the currencies.

=== On the Upgrade page ===
* The Level numbers (LVL) indicate the current level of that category.
* The performance gains are depicted with <font color="green">'''green'''</font> color.
* After upgrading all the categories to level 5, on the Car selection page a MAX symbol is lit beside the (lit/unlit) PRO symbol.

=== How AI Rank is calculated ===
AI racers' ranks are always optimized to be approximately equal to the recommended rank of the event or to the player's car rank, but is still limited to the MAX+PRO rank though. The AI racers always upgrade one level of top speed first before continuing with one level of acceleration, one level of handling, and one level of nitro. The process repeats until the car is maxed out. For example: if the recommended rank of the event is 1500, a [[BMW 3.0 CSL Hommage]] AI racer would be ranked at A1552 (4-'''5'''-4-4). Changing the recommended rank to 1557 changes the AI racer's rank to A1560 ('''5'''-'''5'''-4-4). If the recommended rank becomes 1566, the AI racer is ranked at A1568 ('''5'''-'''5'''-'''5'''-4). Change the recommended rank to 1575, and the AI racer is now ranked at A1608 ('''5'''-'''5'''-'''5'''-'''5''').
If the car has to be ranked past its MAX rank, its Pro Kit upgrades always goes up by one level, but first being upgraded in '''Tires''' (Top Speed + Handling), then '''Suspension''' (Nitro + Handling), '''Drivetrain''' (Top Speed + Acceleration), and finally '''Exhaust''' (Nitro + Acceleration). The process repeats until the car reaches MAX+PRO.

== Asphalt Xtreme ==
[[File:AX Upgrade system.png|thumb|220x220px]]
The upgrade system in Asphalt: Xtreme takes a different approach towards installing the upgrades when compared to the main series. The new system can be considered to be combination of Upgrades and [[Pro Kits]] from [[Asphalt 8: Airborne]]. In addition to requiring sufficient credits to purchase the upgrades, upgrades now require a tech card, material card and upgrade card. All 3 cards can be won in Career races by achieving race stars.
The upgrade categories are identical to Asphalt 8's version but with a graphical redesign and are animated:
# Top Speed - depicted as a turbocharger
# Acceleration - depicted as an engine block
# Handling - depicted as a suspension spring
# Nitro - depicted as a nitrous tank
