3. INTRODUCTION
 Fastest car in the world.
 Can accelerate from 0 to 100 km/hr in
just two sec.
 Top speed of 288 miles/hr (463km/hr).
 Can apply break from this speed to
standstill in less than 10 sec.
 Costs about 205 million $.

4. HISTORY
 The CHIRON bears the initial of ‘ETTORE
BUGATTI’ the father of Italian family that build
unusual high performance cars between 1909
until 1947.
 Later in 1998 ‘Volkswagen’ bought the Rights to
the brand.
 Chiron got its name from Bugatti’s famous race
driver ‘LOUIS CHIRON’.
 Louis has won over twenty Grand prix in his entire
career.

5. ENGINE
 A W16 engine is a sixteen
cylinder piston internal
combustion engine in a four-bank
W configuration. All W16 engines
consist of two 'offset double-row'
banks of eight cylinders, coupled
to a single crankshaft
 The Volkswagen Group 8L W16
engine as configured for the
Bugatti Chiron E is a 16 cylinder
quad-turbocharged engine with
four valves per cylinder.
 Maximum power output is
1500 horsepower, with a
1100 pound-feet of torque.

6. W - ENGINE
In the W engines, these banks of cylinders are aligned at a V-angle of 72 degrees
in relation to one another. As in the VR engine, the cylinders within each bank
maintain a V-angle of 15 degrees.

7. WORKING
It uses four valve per cylinder,64
valves total, with four overhead
camshafts, and bore – stroke ratio
1:1.
Cylinder firing order on WR-16;
1-14-9-4-7-12-15-6-13-8-3-16-11-2-
5-10.
The major advantage of this engine
is packaging; that is it contain high
number of cylinders but are compact.

8. TURBOCHARGERS
 The Bugatti has 4 separate turbo chargers
that allow the engine to be moderately
sized.
 A turbocharger is a turbine-driven forced
induction device that increases an internal
combustion engine's efficiency and power
output by forcing extra air into the
combustion chamber.
 This improvement over a naturally
aspirated engine's output results because
the turbine can force more air, and
proportionately more fuel, into the
combustion chamber than atmospheric

9. COOLING SYSTEM
 The engine actually produces 3000 bhp.
 Half of it is in the form of heat.
 For cooling Bugatti uses 10 radiators.
 Radiators are used to transfer heat
energy for purpose of cooling.
 3 heat exchangers for the air-to-liquid
intercoolers.
 3 engine radiators.
 1 for the air conditioning system.
 1 transmission oil radiator.
 1 differential oil radiator.
 1 engine oil radiator.

10. 7 SPEED DUAL CLUCTH DSG
 Direct Shift Gearbox is abbreviated to DSG.
 It is two separate manual gearboxes
contained within one housing and working as
one unit.
 There are 2 input shafts, one for the in gear
and one for the out gear.
 The two clutches acts on the each input
shaft.
 With two separate transmission shafts two
gears can be engaged at the same time.
 Shift is only the change of the clutch system.

11. HOW DCT WORKS ?
 In a conventional manual transmission, there is not a continuous flow of
power from the engine to the wheels.
 Instead, power delivery changes from ON to OFF to ON during
gearshift, causing a phenomenon known as "shift shock" or "torque interrupt.
 A dual-clutch transmission uses two clutches, but has no clutch pedal.
 Sophisticated electronics and hydraulics control the clutches, just as
they do in a standard automatic transmission.
 In a DCT, however, the clutches operate independently
One clutch controls the odd gears(first, third, fifth, seventh and reverse),
while the other controls the even gears (second, fourth and sixth)
 6 Using this arrangement, gears can be changed without
interrupting the power flow from the engine to the transmission.

12. ACCELERATION
 With 1500 horsepower(1118.55 KW)
and 1100 pound ft of torque the car
reaches to its top speed of 288 miles/hr
(463km/hr).
 The chiron accelerates from 0 to 60 mile
in just 2.0 sec.
 The rear wing adds stability to high
speed run.

13. BRAKES
MECHANICAL BRAKE
 The Chiron’s break use crossed drilled, radially vented
carbon fibre reinforced silicon (C/, SiC) composite discs
manufactured by SGL Carbon which have a greater
resistance to brake fade compared to cast iron.
 An added safety feature, an anti lock braking system
(ABS) has also been installed on the handbrake.
AIR BRAKE
The Chiron can decelerate from 230mph to 0mph in only
7.5 seconds, largely due to the extra down force achieved
with the rear wing, which is raised within 0.4 seconds to a
55° angle.

14. AERODYNAMICS

15. TYRES
 Bugatti uses biggest tyres designed for any
sportscar in the world.
 These tyres are 14.5 inches wide on the rear
wheel, twice as much as normal car.
 These are handmade tyres made by rolling
multiple layers of rubber over a drum.

16. CHASSIS
 The entire body of Chiron is
made from carbon fibre.
 Unlike other cars it don’t have
frame in the middle of the car.
 The passenger compartment
is built with Monocoque
construction.

17. CONCLUSION
 This car is extremely rare
piece of mechanical art.
 It is part aeroplane part car.
 The Bugatti Chiron is unique
piece of engineering and an
extremely expensive car (2.5
million $) that can run over
288miles/hr.
 The new Bugatti Chiron is
expected to come by the end
of next year.
