Enduro Double Down, also known as EDD for short, officially stylized as ENDURO Double Down, and officially called an Enduro DD by Gameloft's social networks  and by some players, is a special series of events available starting with the Enduro Update. The announcement made by Gameloft - Prove you can withstand till the very end in an ever-changing, tough, daring challenge. Double or nothing is the way to go! Risk your progress in order to win BIG! - sets that it is similar to the Research & Development events with a series of challenges to complete. As of the Championship Update, Enduro Double Down events usually follow an R&D event before being followed by a Championship.
Enduro Double Down events involve a story where a professional racer or a group of professional racers holds the car at stake and challenges the player to a series of races featuring merciless racers. Initially, the boss racer(s) underestimates or challenges the player before learning that the player is actually capable of winning, thus causing the racer(s) to cheer them on or continue to challenge them later throughout the EDD.
- Enduro Points
- The basic principle of Enduro Double Down is that the player has to collect Enduro Points (EP; ). Leading up to the boss car as the final reward for the challenge, several points increments award the player other rewards: , , Pro Boxes, Blueprints (as of the Car Blueprints Update), and 2 of the 8 other Enduro Cars used in the challenge. In the case of the Porsche 918 Spyder with Weissach Package's EDD, Blueprints for other Porsche cars are awarded instead.
- Each race won earns the player an (increasing) amount of EP.
- Enduro Challenges
In order to win a race, the goals can be:
- Finish race
- Finish position: X (3, 2, or 1)
- Flat Spins: X
- Flat Spins in One Jump: X
- Barrel Rolls: X
- Knockdowns: X
- Knockdowns without Wreck: X
- Total Air Time: X s
- Drift Distance: X yd / m
- Beat a Race Time of ##:##:###
- KNOCK DOWN THE MOST CARS (Finish FIRST in a Knockdown race)
- Perfect Runs: X
- Perfect Nitro: X
- No Wrecks
- Beat the Ace Racer! (Finish FIRST in an Ace Race)
- This objective was initially known as "Beat the ghost's time!" prior to the Car Blueprints Update.
- In EDD, all types of races can be found – Classic, Flawless, Unplugged, Infected, Elimination, Knockdown, Time Attack, Gate Drift, and Versus (Ace Race), except for Tag Racing & Grand Finale.
- Ace Race
- The points accumulated after each successful challenge are not saved automatically: they can only be banked after winning an Ace Race, a versus race against an orange-colored ghost AI named the "ACE RACER" similar to R&D's Ultimate AI Challenge which comes up at the end of each Tier.
- Double Down
- After the Ace Race comes the option to select from one of three choices:
- Safe - save the amount of EP earned so far (free)
- Double - take a risk to get the double amount of EP earned in the next set of races until the next Ace Race (free)
- Double Down - save the EP earned AND get the double EP for the next races (cost Tokens)
- The group of races before an Ace Race is called a Tier. The length of a Tier is variable, ranging from 3 up to 8 races. The Ace Race must be completed with the car at stake.
- EDD Invitations
- If a challenge is failed, the player must start again from challenge 1. If the player chose the Safe or Double Down option after the last Ace Race, the EP that were accumulated until then will have been saved. If the Double option was selected, all EP earned since the player last chose one of the safe options will have been lost. An invitation is then required to begin a new streak; on the other hand, spending tokens is required in order to retry any failed challenges.
- When an invitation is used, the player can start the streak with either no bonus (free) or by doubling (costs Tokens). As of the Lunar New Year 2017 Update, invitations always start with no bonus.
- Enduro Cars
- In each Enduro Double Down event, there are nine Enduro Cars: the boss car and eight other cars. The first four (sorting by class) are the "low end" cars, while the last five (including the boss car) are the "high end" cars. Two of the eight other Enduro Cars are rewarded for banking Enduro Points.
- There are a few rules regarding Enduro Cars:
- There has to be at least three and at most four cars in the same class as the boss car.
- Enduro Cars cannot be reused in later EDD events unless the EDD event the car was initially featured in was canceled (e.g. 1967 Chevrolet Impala EDD). In this case, the Lamborghini Aventador LP 700-4 was already featured in the Weber Faster One's EDD event, so it was not playable in the Lamborghini Aventador LP 750-4 SV's EDD event.
- In Enduro Double Down events from the 1967 Chevrolet Impala's canceled EDD onwards, the boss car is always an Elite Car. Some events may feature additional Elite Cars.
- In the later phases of the Enduro Double Down event, the two cheapest cars (in terms of purchasing [except with tokens or licenses], maxing out, and Pro Kits) or the two lowest-ranked Enduro Cars are swapped out with the two most expensive ones (in the same terms) or the two highest-ranked non-boss Enduro Cars. For example, in the EDD for the Aston Martin One-77, the Aston Martin DB9 Coupé ( 357,670 (21,750 + 265,900 + 70,020)) and Aston Martin V12 Zagato ( 372,448 (57,500 + 265,900 + 49,048)) (both low-end Class B cars) are replaced with the Pagani Huayra and Peugeot Onyx (both Class S cars).
- At least one of the other Enduro Cars in the event is always an expensive tokens-purchasable car. This can include cars from Research & Development and Championships, as well as Blueprint-unlockable cars.
- However, those patterns have been broken or altered as of the Porsche 918 Spyder with Weissach Package's EDD:
- The Porsche 918 Spyder with Weissach Package is the only car in its class: Class S.
- The Dodge Viper SRT10 ACR-X was in the EDD for the BXR Bailey Blade GT1, repeating old cars. This rule can be broken if a car is revived from a past EDD whose boss car is now unlockable with Blueprints but was released in an update prior to the Porsche Update.
- All of the featured Porsches (959, 718 Boxster S, Cayman GT4, and GT3 RS) have an expensive token price and other than that, all cars can be bought with credits.
- The event has no reward cars and instead features Porsche BP boxes that grant at least 3 Porsche 918 Spyder with Weissach Package BPs while also granting BPs for the other Porsche cars.
- The "low end" cars are still used even from the second difficulty shift onwards, but no longer appear at the last three Tiers, regardless of whether or not the player has saved their EP.
- In addition, the Elite requirement for the Boss car since the Impala/Aventador SV EDD was broken by the Mercedes-Benz SLR McLaren 722 Edition.
- The races become more difficult as the event progresses - within one streak, the longer you progress, the higher the rank the opposition cars will have, and globally the difficulty increases; the rank of your opponent in a given level will not remain the same during the whole event.
- The difficulty will shift twice during the event, once around 7,000 (give or take 2,000), and a second time around 19,000 (give or take 3,000).
- The first shift will move the difficulty one Ace Race up, meaning the user will at the beginning of a streak face races with the same difficulty as initially after the first Ace Race, and the first Ace Race will be replaced by the race that used to be the second Ace Race (the track, the recommended car rank, and the AI Racer).
- The second shift will move the difficulty two Ace Races up, meaning the race, which was initially Ace Race 5 will be presented as Ace Race 3.
- Parts of this analysis is based on sample challenge list from ungeekiness.com.

It was later revived in the same update as the fourth EDD on September 14, 2016, following the revival of the Alfa Romeo 4C's R&D event. In the Championship Update, the event was revived again as the seventh EDD on January 6, 2017, following the Arash AF10's R&D event. The One-77 EDD was held in place of the 1967 Chevrolet Impala EDD.

This event was revived as the 13th EDD in the Porsche Update on August 9, 2017, following the Mercedes-AMG C 63 Coupe Touring Car 2014's revived R&D event. It was revived a second time as the 16th EDD in the Munich Update on November 20, 2017 after the Arrinera Hussarya GT's Championship event.
- Main article: Enduro Double Down/1967 Chevrolet Impala
This event was supposed to be published as the seventh EDD in the Championship Update in 2016, following the Arash AF10's R&D event. However, it was canceled following severe backlash regarding the Impala's heavily unrealistic performance stats and the extreme difficulty of the EDD (e.g. being forced to drive a car with a low triple-digit rank, like the Impala at A775 or Camaro Z/28 at D543, against cars with much higher ranks, like the Maserati MC12 at B1382, Savage Rivale Roadyacht GTS at A1388, and 9FF GT9 VMAX at S1543). In its place, the Aston Martin One-77 EDD was held, later being followed by the McLaren Mercedes MP4-25's Championship.
Many of the cars intended for this event, including the Impala itself (possibly to compensate), would later appear in the Corvette Grand Sport EDD instead.

It was the first time a car event was revived since the car was made Blueprint-buildable, although the revival does not give out any Blueprints; instead the prize car was given out the old way.
