As a result, race technology has influenced many of the components of the car sitting in your driveway - from the basic engine design, to the position of the ignition, and even the rear-view mirror. I have some technologies that have already come to production cars.

3. Formula Racing
• Most sophisticated vehicles
• F1 car demands
 Precision
 Incredibly fast reflexes
 Endurance from driver

4. Touring Car Racing
Road racing that is
run with
production
derived race cars.

5. Sports Car Racing
• Production
derived versions
of sports cars also
known as Grand
Tourers(GTs) and
purpose
built sports
prototype cars
• Compete within
their respective
classes on closed
circuits.

6. Stock Car Racing
•In North America,
stock car racing is
the most popular
form of auto
racing.[4]
•The largest stock
car racing governing
body is NASCAR
(National Association for
Stock Car Auto Racing).

Cup Series race at Dover International

7. Rallying
Involves two
classes of road
legal production
based car; Group
N Production cars
and more
modified Group A
cars. Figure 5: Andreas Mikkelsen driving a Ford Focus
WRC during the 2013 Rally de Portugal [5]

8. Drag Racing
Objective is to
complete a given
straight-line
distance, from a
standing start.

9. Off-Road Racing
In off-road racing,
various classes of
specially modified
vehicles, including
cars, compete in
races through off-
road
environments.

3. Traction Control
4. Tires
5. Brakes
6. Suspension
7. Dual Overhead Camshafts
8. Engine Air intake

11. Transmission
Automatic Transmission
• Makes cruising in the
town easy.
• Shifts gear with no
input from driver(other
than the initial
selection of Drive).
Example:
Direct-Shift Gearbox,
Clutch-less Manual.

12. Time Savers
• In racing, every
second counts, what's
faster than turning a
key is push button
ignition.
•A number of
production cars are
using this racing
technology, which
starts the car at the
touch of a button, not
the turn of a key
Figure 9: Several production cars now feature
push button ignition.[8]

13. Traction Control
• First developed by General
Motors in 1970s.
• Developed for Formula 1
cars in 1980s that inform the
systems on today’s road cars.
• Helps to provide as much
traction as possible – on road
car, it’s there to detect when
car losing grip and to shuffle
the power around as
necessary to keep car safe; on
a Formula One car, the same
is happening in order to bang
in quicker lap times.

cars[8]

14. Tires
• Tires are what connect
the car to the road and
keep the driver in
control. Car racing
teams understand that.
• That's why they use
high performance tires
tailored to their
particular form of
racing.
• Grooves in them allow
the tire to channel
things like water, or
even snow and slush,
away from the car.

15. Tires contd.
Off-Road or All-Terrain tires on
your car, the grooves are likely
very deep and the rubber very
bumpy. That type of tire gives
the car teeth that can grip
uneven or loose surfaces.
Sports Car, the tires likely have
a fewer number of grooves and
the grooves are typically
shallower. That allows more of
the tire's rubber to maintain
contact with the road, making
the car handle better.

16. Brakes
• Disc brakes started
appearing on race cars
in the 1950s.
• Disc brakes are also
easier to keep cool.
When brakes stop a car,
they generate a lot of
friction and heat.
• Ceramic disc brakes
have been used on race
cars for some time, and
are now showing up as
options on some luxury
sports cars.

BREMBO [9]

17. Suspension
• In car racing, it's best to
have all four tires maintain
contact with the track.
• Independent Suspension,
allow each wheel to move
without affecting the
movement of the other
wheels.
• Formula One cars use
multi-link suspensions,
while NASCAR cars tend to
use McPherson struts.
• Both suspension types
are available on a number
of production cars.

Strut(Bottom) [9]

18. Dual Overhead
Camshafts
•A camshaft, or cam,
opens and closes the
vales. If a car has two
cams on engine, or dual
cams, the valves can be
open and shut more
rapidly, allowing for
better performance.
•This type of engine
design first appeared on
race cars in the early
1900s,.

19. Engine Air
Intake
• The more air that gets
into an engine, the better
it will breathe.
•Also, engines give their
best performance when
the air they receive is cold.
• Superchargers are
designed for that purpose.
Superchargers aren't
allowed on
• NASCAR or Formula
One race cars; but are
used in Drag Racing.

20. KERS
•It’s been in the sport
since 2008.
•Kinetic Energy
Recovery Systems
harvest energy under
braking that would
otherwise be wasted,
and use it to
supplement the car’s
motive power. Figure 17: A KERS unit. [10]

21. New Materials
• One of the most high-tech
materials in race cars
is Carbon Fiber.
• Formula One race car
bodies are almost entirely
made out of carbon fiber.
• Carbon fiber is extremely
light and strong, and it's
starting to appear on
production cars.
• Because it's so light,
carbon fiber could radically
increase fuel economy in
production cars.

22. Conclusion
As a result, race technology has influenced many of
the components of the car sitting in your driveway -
from the basic engine design, to the position of the
ignition, and even the rear-view mirror.
I have some technologies that have already come to
production cars, but this is not the end.
Race teams are working on innovating new
technologies for their vehicles and we might also
get some or all of these technologies in our
production road cars.
