See Automotive X Prize for details about the competition. The tables list the 26 teams and 33 vehicles which passed an initial design qualification and were prepared to attempt the Shakedown in May 2010.
Stages:
- Shakedown (May 2010): vehicles are put through four safety tests and a technical inspection. Not strictly an elimination round, some teams were too unprepared to perform the tests.
- Knockout (June 2010): vehicles are put through three efficiency cycles (City/Urban/Highway) and a range test, as well as repeating the safety tests. Vehicles must maintain at least two-thirds of the efficiency and range goals (67 MPGe and either 68 miles or 133 miles range) in order to pass to the next stage.
- Finals (July 2010): vehicles perform the same efficiency, range, and safety tests, this time maintaining at least 90 MPGe. A performance race, combining range with speed, will be used for tiebreaks.
- Performance: All vehicles which pass the Finals requirements are then entered into a tiebreaking performance race, same length as the range test. The contestant who finishes first wins the prize. The participants are penalized for laps above 70 MPH or below 45 MPH, and also for falling below 100 MPGe during the course of the race. This stage is especially challenging for the electric entrants, many of whose batteries only hold enough charge to go 100 miles at 55 MPH.
- Validation (August 2010): remaining competitors are put through dynamometer tests at a national laboratory. These efficiency results are averaged with those taken during the finals, the result must exceed 100 MPGe.

Mainstream
editThis division has vehicles which seat at least four passengers, have four wheels, go at least 200 miles without recharging/refueling, and accelerate from 0 to 60 mph in at least 15 seconds. The prize for this division is $5 million.

Notes:
- The Cornell team experienced an electronics failure during the endurance portion of the shakedown.
- American Hypower was eliminated due to a faulty fuel sensor.
- BITW failed the efficiency tests due to a missing cap on their turbocharging system.
- Illuminati Motor Works passed the main knockout stages, but failed the 0-60 test because their transmission broke.
- Both of Edison2's mainstream entries engines were damaged during Coast Down at the Chrysler Proving Ground. Edison2 has been granted a waiver and is still in the competition for $5 million while no longer having to undergo validation at Argonne National Laboratory.
Alternative
editThis division has vehicles which seat at least two passengers side-by-side, go at least 100 miles without recharging/refueling, and accelerate from 0 to 60 mph in at least 18 seconds. The prize for this division is $2.5 million.
| Team | Vehicle | Fuel | Shakedown | Knockout | Finals | Performance | Validation |

| ZAP | Alias | Electric | Passed | 87.5 MPGe* | 121.8 MPGe | 4th: 96 miles | 126.4 MPGe |
Notes:
- TW4XP could not attend the initial shakedown due to the air travel disruption after the 2010 Eyjafjallajökull eruption.
- VLC 2 experienced engine overheating so they couldn't complete the range test.
- The Aptera 2e stalled due to overheating for six minutes during the range test, resulting in a penalty lap.
- Tata lost an appeal due to a charging issue that prevented them from taking the range test.
- Amp Sky ran out of energy during a penalty lap of the Finals range test.
- WWU's Viking 45 could not complete the accident avoidance test within six tries (the new limit imposed at the Finals) due to a damaged suspension.
- Aptera lost power after the first few laps of the performance race. It died completely at mile 34. The regenerative braking system blew fuses in the battery pack trying to charge a full battery.
- Zap Alias ran out of juice at mile 96 of the performance race.
- In a consolation race, Tata lost power after only a couple of laps, possibly due to a ground fault in their electrical system. That race was won by Tango, followed by Spira's upset of Amp Sky which ran out of juice a mile from the finish! Letting the battery relax, Amp Sky limped over the finish line a few minutes before the overall time limit expired.
- After penalties were applied, the performance race was narrowly won by Li-ion Motors' Wave II (1 penalty, 125 MPGe) only 0.179 seconds ahead of Raceabout (2 penalties, 100 MPGe). TW4XP came in a distant third (4 penalties, 137 MPGe). In an amazing display of camaraderie, four of the five contestants (excluding Raceabout) agreed to split the purse if won. Li-ion later reneged on the agreement.
- Aptera found that a glitch in their charging system caused inaccurate mileage to be reported. Without the glitch, it would have been 178.2 MPGe in the finals.
Tandem
editThis division has vehicles which seat at least two passengers front-to-back, go at least 100 miles without recharging/refueling, and accelerate from 0 to 60 mph in at least 18 seconds. (This configuration is expected to allow better aerodynamics due to a smaller frontal cross-section area.) The prize for this division is $2.5 million.

Notes:
- K-Way MOTUS could not attend the initial shakedown due to the air travel disruption after the 2010 Eyjafjallajökull eruption. They experienced a motor failure on the weekend after taking a make-up shakedown.
- FVT passed the efficiency tests but failed the emissions test. The eVaro electric drivetrain was so efficient, that the motor had not turned on at any other time during the competition.
- Edison2's tandem VLC had a breakdown before the safety tests.
