For my EPQ I have decided to research why race cars today
have become more efficient. I find this topic that I have chosen interesting as
I have always had an interest in cars all my life and I would like to delve
into the history of race cars as they seemed to have changed a lot over the
last century from the brief information I know. Today’s race cars are a lot
different from the race cars from the past. The aim for every race car since the first
one which was Charles Duryea’s Motorized Wagon to one of the most recent race cars that is the LaFerrari FXX K, is that they make the car as fast as they possibly can; So
overall most race cars are the same as the car maker uses the best technology
to create the fastest car possible. However linking back to the Charles
Duryea’s Motorized Wagon (As pictured on the right) they also had to think
about how to stop the car from breaking down. 1 By the end of my research I
desire to achieve the reasoning of why race cars have become so more adequate
in recent history and explore the history of race cars that I would never think
I would have ever have knowledge about. For my primary research I am going to
email Ferrari and ask about their latest race car and find out what they have
chosen to endeavour to make a more efficient race car and then for my secondary
research I am going to use reviews and news articles to get a brief knowledge
from someone’s perspective. At the end of my research I look forward to
discover how cars have become more efficient.   Engine The 1890’s racecars
didn’t have the most power in a racecar as the engine was a whopping 1 cylinder
and it had a maximum of 4 horse power, whereas the Ferrari FXX K has a petrol
engine and electric engine. The electric engine puts out 187 horsepower and the
petrol 1,036 horse power which
is evidentially a lot more than Charles
Duryea’s Motorized Wagon. Car engines are
created around cylinders and it can be anything from two cylinders
to eight cylinders; in the cylinders is where fuel burns. Cylinders are mainly
made out of cast aluminium or iron which is very strong and act as football
pumps, there are perfectly fitted pistons that continuously work by sliding up
and down inside of the pistons. In conclusion to this research about race cars
engines, they have changed to be more efficient as now they have direct
injection technology which means more of the fuel is burnt more efficiently.
Luxury Your average race car from the 1890’s would have a stretched leather
seat for two people, but you won’t find the new fancy gadgets or soft race car
suspension, or the noise and vibration from the car and the road. Race cars
mainly use these primary materials to make up the cockpit of the car;
aluminium, titanium, carbon fibre, and leather. Most car bodies were made out
of steel as it is strong and very
easy to work with and also cheap. Steel can be used for parts of the
car like the chassis, wheels, exhaust, engine and roof; if anything of the car
broke it was easy to repair and replace as it is cheap. However, aluminium is
also a popular material for cars as it is stronger and lighter than its ferrous
friend, steel. Aluminium also doesn’t rust but it is a lot more expensive than steel so it is not used on cheap cars. As more car
manufactures used aluminium it became very popular with race cars but carbon
fibre came into the race car world which is mainly used for race cars. Gearbox
A manual gear box was originally the only
choice for a cars
transmission, then the world was introduced
to automatic gearbox and it got exceedingly popular with car
manufacturers. Also in 1989, Ferrari put a paddle shifted semi- automatic
gearbox in its formula one car. Now most of the race cars nowadays have paddle
shifted gear boxes so drivers can get the maximum potential out of their race
car.
