Short Ultra4 history

In 2007 Dave Cole and Jeff Knoll had the idea of organizing a new competition style, totally different from those existing in the States. The King of the Hammers was born in the Johnson Valley (CA) combining the desert races and rock crawling competitions.

 

After the first King of the Hammers, the success and interest was so great that the Hammerking Productions were created, the public was invited to watch the race, the first sponsors appeared, the Ultra4 category was defined and the Ultra4 Racing championship started.

 

Ultra4 Europe, in 2012, brought this style of racing to Europe gaining great appreciation from the Ultra4 teams and fans. In just a few years, from a race they moved on to a real championship that today brings together the best European drivers.

Not just Unlimited

The 4400 class is the original class that started the King of Hammers race. Year after year these rigs have evolved to become increasingly powerful and performing. For their important technological development, the 4400 are considered by many people as the  “Formula 1” of 4x4. Said this, it is important to know that it is possible to participate in Ultra4 Europe competitions also with other types of vehicles.

The championship

The drivers of the Ultra4 Europe championship compete not only for the victory of every single race but also to become European Champion. At the end of the year the sums of the points that everyone has acquired are made; who has more points is the champion!

With this article, we will learn more about this two aspects that are fundamental to a better understanding of the Ultra4 Europe championship: the distinction of classes and the allocation of points.

 

Ultra4 Europe classes

The 4x4s participating in the Ultra4 Europe championship are divided into 5 classes: Stock, Modified, Legend, Unlimited and UTV.

 

4600 Stock

ultra4 europe 4600 stock classes

The spirit of the stock class is to allow OEM and aftermarket vendors the opportunity to showcase their products while providing a venue for teams to compete in a true drivers class in vehicles that closely relate to street driven versions of the same. The driver of record will bear the burden of proving legality of any part of their vehicle including but not limited to; Motor/Transmission, frame length, suspension configuration.

 

ELIGIBLE VEHICLES

1) Any and all four-wheeled, four-wheel-drive production automotive based vehicles are eligible for competition, providing they meet all the rules and regulations specified herein, and with the following limitations and exceptions: Minimum of one thousand (1000) units were produced by the original manufacturer for given model year, for given market/region. Vehicles produced for foreign markets may be imported for competition, but features and/or components found on vehicles produced for different regions/markets shall not be combined in any one vehicle if doing so would violate any rules or regulations specified herein.

 

FRAME & BODY

1) Stock frame (frame is considered to be the primary frame rails and all permanently factory cross members) must be retained, and must be complete and unmodified. No material may be removed for any reason and no section of the frame may be 'massaged' or re-shaped with the following limitations and exceptions: The rear portion of the frame and rear cross member may be removed or trimmed for the sole purpose installing an aftermarket rear bumper. Frames may be reinforced by adding material.

2) Stock body (body is considered to be the full cab, including all interior and exterior sheet metal, bed, doors, hood, fenders, grill, etc.) required. The body must be complete and unmodified, with the following limitations and exceptions: Holes may be cut in any part of the body for the single and exclusive purpose of allowing roll cage tubes and transmission/transfer case linkage to pass-through the body. Open holes must be kept to within. 5"(12.5mm) of the diameter of any tube or linkage that passes through the body, with further restrictions related to holes in firewalls specified in Section 8.2.12, Subsection 4. The exception to this rule is the allowance for rocker panel protection limited to the area between the wheel wells. You may cut into the body and/or reinforce this area. You may not interfere with the mating surface of the stock door and doorsill. The stock doorsill must be retained and unaltered.

3) Stock doors may be modified to create half-doors and/or may also be replaced with tubular doors. Doors must open and close, bolted on panels are not allowed.

4) Stock windows (glass) are not required, but are permitted, providing they meet DOT regulations. Alternatives to traditional safety-glass may be allowed, on approval of Hammerking Productions Inc.

5) Front inner fenders must be complete and unmodified, with the following limitations and exceptions: outer fenders (wheel well openings) may be trimmed for the single and exclusive purpose of allowing for tire clearance. Modifications to the outer fenders must preserve the look of the stock wheel wells, as originally manufactured, and must not be trimmed excessively (no more than a 2" (50mm) gap between any part of the outer fender and the tire at full compression).

6) Front outer fenders may be replaced with OEM-style aftermarket fenders (flared fiberglass fenders are permitted).

8) Extensive damage to any portion of the frame or body (prior to race start) may be considered illegal modifications, and repairs may be required, as determined by, and at the sole discretion of the Chief Technical Inspector.

9) Stock body mounts may be modified or eliminated, with the following limitations and exceptions: The relationship of the body to the frame must remain within 1" (25mm) of stock configuration, as originally manufactured. Stock body mounts shall not be modified or eliminated for any reason other than to allow any part of the roll cage to pass through the body in order to be securely attached to the chassis.

Ultra4 Europe points

ultra4 europe

Ultra4 Europe uses the same point scoring system as last year, which is the same as the global scoring system for all Ultra4 races. So this gives everyone the same system and possibilities.

Points are assigned as follows for each race in the ULTRA4 Series: 1000 points for winning, 975 points for 2nd, and 965 for 3rd.

For every driver from 4th place through the last driver that completes 2/3 of the race (determined by miles or laps depending on race format), each driver will receive 5 less points than the driver who finished ahead of them. Example: 4th is 960, 5th is 955, 6th is 950 through the last driver to complete 2/3 of the race. The 2/3 mark will be announced on site at drivers meeting prior to race.

For the BFGoodrich Tires Ultra4 European Championship is allowed to drop one race. This means that four of the five races are calculated. These four scores determine the final place in the championship. In case of a tie, the team with the highest place in the last round of the championship will get that position.to abandon a race.
