There are three types of GT motors. These are GT1, GT2 and GT3 and the following are all motors. Unlike LMP motors in endurance races, they have the same shape of the motorcars you can obtain from the showroom. These GT motors are not based on the average motorcars you see on the streets, but on the best range sports motorcars, like Porsche 911′s, Aston Martin, and Ferrari’s. These types of motorcars are dear to purchase and turning them into race winning motors can cost millions and millions of pounds. It would be very hard to go through all the design specifications of GT1, GT2 and GT3 types without writing a book, but here is short description of what is allowed in each class of GT motors.

GT1 motors are the fastest of all the GT types, these motors have to be based on production motorcars where at least 25 motorcars a year are sold. These motorcars are heavily modified to turn them into race cars, and in this class teams are allowed to use exotic materials, the biggest wings, the biggest wheels and the biggest breaks. All of this makes GT1 motors, the fastest of all GT motors, and only have a similar look of the motorcars and the wiper blades are the same as the original motorcar.

GT2 motors are very similar to GT1 motors, they also have to be based on production motorcars. However, they are not allowed to use carbon fiber in the construction, the wings are also smaller as are the wheels and the brakes. This results in a heavier motor with less aerodynamic and mechanical grip, which is therefore slower round a race track. These motors are however less expensive to develop and run, making them a good alternative for teams with a smaller budget.

GT3 motors are basically road going motorcars that have had all the seats and other luxuries stripped out. Then the one race seat is added along with an FIA approved fuel tank, seat belts and safely cage. This is the cheapest class of GT motors to develop and run. All types of GT motors must remain road legal motorcars, this means that all the lights and wiper blades must all work after being race prepared, although you would not be able to use these motors on the road without first getting some road legal tyres, as racing tyres do not meet the minimum 1.6 mm legal requirements.

To win in any of the GT types it takes a lot of attention to detail and not one thing can be overlooked, just take the wiper blades for example. It is important to make sure the wiper blades are in good condition, just in case it rains during the race, and replacement wiper blades will have to be fitted to the motor regularly, maybe as often as once a event. The replacement wiper blades that are usually used are called flat wiper blades, these wiper blades could make the difference between first place and finish second. How could you think this is possible, unless the race was wet and the flat wiper blades were necessary to enable the driver to see? But in a dry race the flat wiper blades could also make the difference and this is because of their frameless design, which is lays closer to the windscreen giving an aerodynamic advantage over classic wiper blades. This advantage may only be a little one but it’s all the small things that lead to race victories. The flat wiper blades can make the airflow over the windscreen smoother, resulting in a little bit more speed, a bit more down force from the rear aerofoil and a bit of better fuel economy. All of which over classic wiper blades could make a lot of difference, and this difference could be the difference between first place and finish second.
