This year will be an epic race season! Everyone will want to take part!

The first King of the Hammers-style European race took place in Wales in 2012 and since then, Ultra4 Europe has evolved, grown and established itself as one of the leading race organizers in the Old Continent.


As happened in the United States with the King of the Hammers, also in Europe, Ultra4 introduced a new style for offroad racing and a new concept of offroad vehicles. After more than 10 years, Ultra4 racing style is now a solid reality in the large European offroad world.


If the big and powerful Ultra4 vehicles of the 4400 class are recognized as the "top guns" of this specialty, everyone can participate in the Ultra4 Europe races thanks to the different Vehicle Classes that the Ultra4 technical regulation allows to its events. This aspect is very important and truly puts all participants in each class of vehicles admitted by Ultra4 Europe on the same level of importance.


It is not necessary to have a big rig with a super-powerful V8 to take part in the Ultra4 Europe events. On the contrary, the different 4x4 categories are made so that everyone can come and race in the Ultra4 Europe competition format. It is obviously necessary to respect the basic rules of safety concerning your vehicle but be aware that a small Suzuki, an old Patrol will be just as welcome as the latest, most equipped prototype.

2023 European Championship

The European Championship is aimed not only at drivers who can go racing in different countries and take part in the whole season, but also at those who only wish to go and ride in part of the races. From North to South, from East to West, there is bound to be a race near you, take your seat in the 2023 Ultra4 Europe Championship.

The legendary Rallye Breslau enters in the Ultra4 Europe calendar

On 14 October 2022, Dave Cole (Hammerking Production) and Alexander Kovatchev (RBI Sport) have written an important new chapter in the offroad history!


Ultra4 and RBI Sport with Rallye Breslau have joined forces to write an important new chapter in the history of the international offroad scenes. This first step that Dave Cole and Alex Kovatchev have taken together is the prelude to a more assiduous and fruitful collaboration that will produce an incredible game changer in the offroad world in the future.


2023 will see the first step of this collaboration with the Ultra4 Europe teams who will participate in the Rallye Breslau in the Ultra4 dedicated category. 

The winners of each championship category will have the opportunity to participate in the 2024 King of the Hammers

For everyone, Ultra4 Europe fans and Ultra4 Europe teams being able to be in Johnson Valley at the King of the Hammers is the dream of a lifetime.


For this reason, Hammerking have decided to offer to all class winners in both the European, British, and Southern championships the shipping costs to USA for King of the Hammers 2024.

Which vehicles can participate? All Ultra4 Europe classes

Not just 4400 Unlimited to participate in Ultra4 Europe races!


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.


That said, it is important to know that it is possible to participate in Ultra4 Europe competitions also with other types of vehicles.



These cars compete during the main King of The Hammers race on KOH Week. 4400 Drivers have to earn a spot to compete in King of The Hammers. These cars are not limited on tire size, engine or chassis design, other than to meet the safety requirements for the class. Unlimited cars must have a transfer case and be able to be driven in 4WD. These cars can be straight axle, or independent suspension (IFS - IRS). They are the ultimate and original design of the Ultra4 vehicle, capable of any terrain, any speed and no limits.


- 4600 STOCK

This class has been racing in Ultra4 since 2012. It is one of the 3 classes that races on KOH week during the 4WP Every Man Challenge. Currently, these cars do not have to qualify to race in the EMC race during KOH Week. At regional races, this class usually races with either the 4500 or 4800 cars.


The spirit of the stock vehicle is to allow OEM and aftermarket vendors the opportunity to showcase their products whilst providing a true driver's class experience that closely relates to street driven versions of the same vehicle. Fairly strick technical criteria makes sure that a Stock vehicle is competing in a level playing field of vehicles but still allows the driver to design his race car to the optimum for driving advantages whilst still being compliant within the rules.


Class Characteristics:

. Stock OEM frame

. Factory engine

. Factory transmission

. 35” DOT approved tires

. Single 2.5 inch diameter shocks per corner

. Mechanical steering



This class has been racing in Ultra4 since 2012. It is one of the 3 classes that races on KOH week during the \Every Man Challenge. At regional races, this class, if large enough, races on their own or can be on the track with the 4600, 4700 or 4800 cars. As a vehicle, the class allows for significant modification of a standard vehicle and in some cases can be as capable as a 4400 vehicle in the suspension, engine and performance.


Class Characteristics:

. Modified OEM chassis or OEM style chassis

. 2 -2.5 inch diameter shocks per corner

. Mechanical steering

. 37” DOT approved tires


- 4800 LEGEND

This class has been racing in Ultra4 since 2014. It is one of the 3 classes that races on KOH week during the 4WP Every Man Challenge. These cars do not have to qualify to race in the EMC race during KOH Week. This class has been one of the fastest growing classes in Ultra4 as older Ultra4 cars can enter this class as long as they meet the requirements. The vehicles follow the tradition or original technical format for the Utra4 vehicles that were racing in the beginning!


Class Characteristics:

. Front mounted engines only

. Vehicle must contain 2 seats side by side

. Single shock per corner

. Max 37” DOT non-sticky tires

. Only solid axles allowed (not IFS or TTB)


- 4900 UTV

Utility Terrain Vehicles or UTV are by far the fastest growing class in Ultra4, light, fast, super nimble vehicles, this class has grown in popularity as the vehicles are easier to transport, own and maintain. Vehicle is defined as a standard production based "side by side" with powersports based belt driven drivetrain.


This class is growing as the variety of vehicle designs increases - it already has sub classes in Ultra4 which cater for the increase in engine sizes available, typically 800cc and 1000cc turbo and non turbo but with the newer 2000cc vehicles coming in, the sub classes will allow vehicles to compete at similar levels.



The newest and very much the European class within the Ultra4 Classes, this class is only now in its third year of running and still being evolved. It was originally introduced as a class to entice Teams to take part in Ultra4 events, had a winch challenge capable vehicle and wanted to come and play. Vehicles that enter in Winch Rally Raid class are very capable vehicles, in their own right, full challenge spec, not always the fastest of vehicles, often diesel powered but a competitive vehicle none the less. This class gives them a more level competitive playing field whilst still getting the full effect of Ultra4 events.


WRR courses include terrain that requires a different mindset to traverse and this adds to the overall flavour of Ultra4 racing. Typically, WRR would be more at home doing the Rally Breslau Extreme class but competing with Ultra4, gives a totally different view of the speed aspects of offroad unlimited racing. Teams have made the transition from WRR to 4400 or 4800 class, altering their vehicles to fit the technical requirement for these classes, proving the diverse nature of offroad competition vehicles.
