Having sufficient space around the car is important, as a cramped workshop will be difficult to work in. The tools to modify the engine, chassis and bodywork can add considerably to the cost of your project if you don't already have a workshop, but borrowing or renting items is also an option. Many components permitted for Rally racing can be bolt-on type components and therefore are within the mechanical skills of most people. Challenges include the number of components which are changeable, and the difficulty in changing them i.

Things like engine removal , which may require specialized workshop tools. For occupant safety cell structures that must be custom fabricated, there is the additional requirement of fitting it into the vehicle and of locating mounting points that do not compromise the uni-body chassis.

The base vehicle cost can be economical if purchasing a used donor vehicle up to years old. Purchasing much older donor vehicles may open the possibility of corrosion damage and metal fatigue. Used donor cars will offer a lower cost entry point, especially as the car will be a "development platform" for both the builder and driver.

Racing parts will add to the cost of the base vehicle significantly. Suspension on a rally car is very important, and this is an area where race-proven parts are definitely worth the money. Beyond this, if you have adequate knowledge, it is possible to select areas of modification that provide maximum value and keep costs to a minimum. The effort depends on the number of areas that are modified, which is a good reason to start in entry-level club rallying or in Autocrossing.

If your modifications are performed a little at a time, the effort will also be manageable and your experience will grow along side your knowledge.

Rally racing, by nature of its more punishing racing environment, can consume a larger budget through racing tires, engine rebuilds, and damage repairs. If using Autocross or club rallies as your "school", the costs can be kept much lower initially and the feel of the car can be determined without body damaging obstacles to hit.

Ultimately, however, the rally course with its dependence on co-driver, and its on-road and off-road dangers must be run to gain rallying experience. Trailering for non-street legal or race-only machines. Drive to the rally if street-legality is maintained. Page: 1 2. Rally Contents 1 Design and Construction 1.

A suspension canister with knobs is used to adjust the softness of the suspension via compression. Rally tyres have side walls which are over one inch thick. Most INRC cars use tyres made with a special compound, especially for rallies — they cannot be used for on-road cars.

Dean uses tyres manufactured by JK Tyres for rallying. The tyres have an extremely strong sidewall which absorbs more impact in off-road conditions at high speeds.

The tyres come in hard, medium and soft compounds, which drivers pick based on the terrain of the stages. Engines are tested and tuned for best performance in rallies. Dean competes in INRC2, which does not allow for turbo in engines. Nevertheless, the regulations allow for many improvements to be made to the engine. Engine control unit. The engine control unit manages fuel supply and air pressure in the engine. Dean has a modified engine control unit which helps him boost the performance of the car.

Meet Druva Chandrashekar, a rally driver obsessed with motoring memorabilia Bengaluru-based Druva Chandrashekar has been …. Skid plate. Rally cars are specially fitted with an impact guard called the skid plate, which is under the engine. It helps protect the gearbox from impact in case a stone hits it during high-speed rally stages.

International rally cars tend to use carbon fibre skid plates to reduce the weight of the car. Bonnet and air scoops. Bonnet scoops help hot air from the engine to escape out of the car.

Temperatures can drop far beyond sub-zero and soar as high as 30C. Press material Contacts. The high-performance cars that compete in the World Rally Championship are based on standard road cars.

Built for rallying, they must withstand challenging terrain and weather. So how are they made? Play This website uses Vimeo as an external video player.

How early rally cars evolved Rallying can be traced back to the nineteenth century and the Paris-Rouen Horseless Carriage Competition.

Prizes were awarded to the vehicles by a jury based on the reports of the observers who rode in each car. Early rally events saw car-makers enter works cars, while up until World War II, rally cars tended to be standard or near-standard production cars. This had the support of manufacturers because it created a relatively even playing field. After the war, most competing cars were saloon or sports cars, with only minor modifications to improve performance, handling, braking and suspension.

This opened up the sport to a wider audience. In the s, car companies started to introduce special models or variants for rallying.
