222-403: A region-wide basis, with Motorsport UK overseeing rules and regulations. Some people choose to start singularly, particularly if they compete in a rally car. The sport is relatively low risk as there is or should be nothing to hit. However, if you wish, you may do double car starts. Most people opt for this, although some competitors choose to do 3 and 4 car starts whilst still competing against

259-573: A regular event. The SCCA National Championship is held in September in the Midwest . Currently (2024 and prior) held in Lincoln, Nebraska. The event takes place over 4 days with half the drivers competing on the first two days and half the last two days. Two different courses are driven with winners determined by combining best times from both courses. It is considered the largest amateur motorsport racing event in

296-474: A selection of the ten FIA European Autocross Championship events also host rounds of the FIA European Cross Car Championship (7 competitions in 2022) and the FIA Cross Car Academy Trophy (5 competitions in 2022, reserved for drivers aged 13 to 16). The championship is run on circuits on natural terrain, with any type of unsealed surface, from 800 to 1,400 metres in length. Autocross races involve

333-484: A short course using automobiles on a dirt or grass surface, excepting where sealed surfaces are used in United States. Rules vary according to the governing or sanctioning body, such as the length of the course, the amount of permitted attempts, or whether competitors start the course individually at intervals or at the same time as others. In this latter form, Autocross differs from other forms of motor racing by using

370-425: A specified intake restrictor to keep power output on par with the 500cc 493 engine. Cars running the 593 engine are also required to run at a higher minimum weight to maintain parity with the older 494 and AMW engines. The 593 remains in production for Ski-Doo to date, rebadged from "500ss" to "600" in 2010. In 2021 SCCA allowed the use of the rotax 593HO or high output. Engine specifications are tightly regulated by

407-460: A system of heats or alternative timing methods for the classification rather than racing for position and declaring the first across the finish line as the winner. Autocross began in the United Kingdom in the early 1950s at an amateur level within local motor clubs using temporary courses marked on grassy fields to not cause damage to any cars. The creator of rallycross , Robert Reed, wanted

444-428: A tight dimensional ruleset. Engines are specified by the ruleset, and builders are not allowed to modify engine internals. Instead of traditional dampers and springs, F500 cars utilize a very simple elastomeric spring medium contained in a cylindrical canister. The rules state the elastomer must be 2" in diameter by 1" in thickness, but the design and implementation of the elastomeric springs (commonly called "pucks" by

481-547: A time running against the clock, with traffic cones defining the path to be driven, and an emphasis on car handling and precision manoeuvring. Autocross courses can be as short as 800 metres or several kilometres long. Courses may be temporary and marked by traffic cones which can be reconfigured during events, or be permanent tracks with approval by a motorsport body. Events typically have many classes that allow almost any vehicle, from production touring cars to purpose-built racing cars. The international body for autocross,

518-505: A version of autocross with more spectator-appeal to be made for television, using professional racing and rally drivers and teams; and courses featuring jumps, sharper corners and a mixture of sealed and unsealed surfaces. In the United States, the motorsport called autocross is more like the UK and European sport of Autotesting or Autoslalom , and what is called rallycross in the US is more like what

555-737: Is a 499cc rotary-valve engine. Like the AMW, the Rotax utilizes a 2 into 1 "Y" exhaust manifold and a single tuned expansion chamber exhaust. The Rotax engine utilizes the same 38 mm Mikuni VM carburetors as the Kawasaki. The Rotax engine has become, by far, the most popular engine in F500 road racing. The Rotax 494 went out of production for Ski-Doo following the 2000 model year. Ski-Doo/Rotax ended support for it shortly thereafter. Some parts however, are still available through dealers and online outlets. In 2004 SCCA added

592-605: Is also uncommon, and not usually necessary on a typical autocross course. They are similar to the Japanese gymkhana , another type of handling competition. Gymkhanas are tighter than motorkhanas and autotests, with numerous 360-degree turns around cones and courses which loop back on themselves. Fast times require sliding, and resembles a combination of autocross and drifting . Gymkhana does not usually require backing up. In ProSolo, an SCCA-sanctioned programme of autocross, two cars run side by side on mirror-image courses after starting at

Several chassis manufacturers produce different designs to

666-466: Is known as autokhana. Motorkhana (Australia and New Zealand) and autotesting (the UK and Ireland) are also similar disciplines. With speeds rarely exceeding 40 mph (60 km/h), motorkhana and autotesting are slower than American autocross, require hand-braking, and have sections that must be navigated in reverse. Autocross speeds can exceed 60 mph (100 km/h), and courses requiring drivers to reverse are generally prohibited. Hand-braking

703-461: Is rarely used these days. The SCCA also now allows the use of 600cc motorcycle engines with a sequential transmission as an alternative to the two-stroke engines. The usage of this engine requires a 28mm intake restrictor and a higher minimum weight of 900 pounds for the car in order to keep performance the same as the two-stroke powered cars. Cars using these engines are often unofficially referred to as Formula 600 cars, although they still race in

740-614: The FIA , and the French body, FFSA , both provide technical specifications for cross cars , lightweight buggy cars. Australian Autocross was sanctioned by the Confederation of Australian Motor Sport , which defined it as a speed event held on a dirt course less than two kilometres long. Eligible vehicles ranged from standard road-going cars through to purpose-built buggies to full racing or rallying -prepared machines. Drivers could begin competing at

777-474: The 2003 model year. Support for it ended in 2007. As with the 494, some parts are still available through dealers and online outlets. In 2011 SCCA added the Rotax 593 to the list of approved engines. The 593, (more commonly known as the Ski-Doo 500ss) is a 600cc version of the reed valve 493 engine.

Presently, there are many local clubs which host across the UK, although the main regions hosting Autocross events are: AEMC for East Anglia, ANECCC - North East, and, the ASWMC for the South-West region. The ASWMC, for its part, now has 13 different Championships, which attract around 250 contenders each year. The regional autocross events also have different formats. For instance,

888-437: The Rotax 493 to the list of approved engines. The 493 has the same bore and stroke as the 494. However, unlike the 494, is a reed valve engine. It also runs Mikuni VM series carbs and the "Y" exhaust manifold like its cousin the 494. Cars running the 493 engine are required to run at a higher minimum weight to maintain parity with the older 494 and AMW engines. Like the 494, the 493 also went out of production for Ski-Doo following

925-539: The SCCA. No engine modifications are permitted in formula 600. Engines must be run in stock form "as delivered" from the factory. No aftermarket parts, port modifications, or other variations from stock configuration are allowed. This helps keep costs down and means close competition on the track. Two-stroke F600 cars use an advanced Continuously Variable Transmission (CVT), similar to that used in snowmobiles. These simple belt driven automatic transmissions are tuned to optimize

962-765: The South West follows the traditional two-car start, except for the 4 abreast Sandocross that used to run at Weston-Super-Mare, while the North East region involves 4-car autocross. Cars compete against the clock, and start at the same time. A well attended international series is the FIA European Championship for Autocross Drivers. The FIA European Autocross Championship is a racing competition held on natural terrain circuits with unsealed surfaces ranging from 800 to 1,400 metres in length. Up to 10 cars race simultaneously in qualifying heats, followed by two semi-finals and

999-400: The UK and Europe call autocross. The Sports Car Club of America (SCCA) publishes rules for autocross, which are also used by many independent clubs, as well as hosting national events and championships within its Solo branded series. The National Auto Sport Association brands its version of US-style autocross as NASA-X, Both take place on sealed asphalt or concrete surfaces, one car at

1036-507: The US, both autocross and slalom are disciplines included in the SCCA's branded time trial series, Solo, and the terms are commonly used interchangeably. Other regions of the world use different names. Parts of Canada and Eastern Europe (including Russia , Ukraine , and Moldova ) have an autoslalom discipline and events. In the United Kingdom , the closest discipline to autocross is known as autosolo . In Malaysia and Thailand it

American autocross events (also called "Solo", Auto-x" or "Autoslalom") are typically held on flat, paved surfaces such as parking lots or airport tarmacs, and usually have a new course for each event, marked by traffic cones. Autocross is one of the most accessible and affordable forms of motorsport, and autocross events are open to novices. Because autocross events use rubber traffic cones to define

1110-474: The clock. The British autocross began in the early 1950s when clubs organized timed runs around courses set on farmers' fields. By 1954, Taunton MC organized the first ever autocross series in the United Kingdom. This, however, was only repeated in 1959 when the club was awarded the permit to hold the British National Autocross event. Shortly, thereafter, the sporting event caught on and, by 1963,

1184-753: The course, and are typically run on paved surfaces with few obstructions, the hazards and barriers to entry are low. While speeds are generally no greater than those encountered in legal highway driving, the combination of concentration and precision manoeuvring gives drivers an experience similar to that of a full road course race . Competitors range from casual participants driving their commuter vehicles, to dedicated competitors driving purpose-built cars with special tires. There are classes accommodating varying degrees of car modification, as well as classes specifically for women and children. Many events are open to spectators. Many local car clubs offer autocross novice driving schools to help drivers feel comfortable before

1221-430: The early 1980s. Parts for these engines are becoming more difficult to find. The AMW 500L-85 engine, built by Two Stroke International was introduced to F500 in 1994. It is a 497 cc reed valve engine using twin 38 mm Mikuni SuperBN carburetors. To keep the performance of these larger, more powerful engines in line with prior engines, SCCA mandates the use of a spec Y exhaust manifold and single tuned pipe on

1258-469: The power curve of a two-stroke engine, constantly keeping the engine at its peak power. One of the key benefits of the CVT is that it is a stepless transmission. This allows all of the engine's power to be transmitted to the drive wheels at all times. Motorcycle-engined cars use the same sequential transmission used in the motorcycle that the engine came from. This is typically operated by paddle shifters attached to

1295-501: The same Formula 500 class. The Kawasaki 440/A engine, produced by Kawasaki , is a 436 cc piston port engine utilizing 38 mm Mikuni VM series carburetors and a tuned dual exhaust. While this engine is no longer competitive in road racing, it is still widely used in Solo II and Autocross events.
