3. HOW A HYBRID CAR WORKS ?
It is a vehicle with parallel hybrid configuration

4. 1)EXTERIOR (BODY &
DESIGN)

5.  Great stability with light weight construction and plenty of protection for the
parts in the cabin….
 It is built on carbon-fiber reinforced plastics monocoque interlocked with a
carbon-fiber reinforced plastic unit carrier.
 Plenty of Porsche's trademarks are there which boasts a sloped nose, along
with a sleek roofline that tapers all the way down to the rear end.
 Two piece Targa top graces on the roofline which will give you the pleasure
of driving in open air.
 At its front, you can find shapelier headlights that you will see on the rest of
its lineup.
 The front fenders are also far less bulging then on the other models in its
line.
 On the backside there is a massive dual-pedestal spoiler to add extra
downforce.
 Porsche fitted the engine’s main air intakes at front of rear wheels.
 Fixed roll-over protection system.
 Ergonomic Design.

6. 2)INTERIOR

7.  Basically the interior is meant for offering a great driving experience to the
driver.
The infotainment block that is
housed in the lifted centre
consol.
Holding the controls that
are important for the
drivers.
WE CAN CLASSIFY IT INTO TWO AREAS:
1
2

8.  In the interior you can find black and silver color combination with green
contrasting piping on the door panels.
 Instead of that ugly hard plastic it will offer you a soft touch interior with 3
spoke, multifunction sports steering wheel and sport seats wrapped in
leather.
 The open center console is encased in aluminum and divides the cockpit’s
function areas with visual clarity.

9. 3)SUSPENSION & CHASSIS

10. Double-wishbone front axle
Optional electro-pneumatic lift
system on front axle
Electro mechanical power
steering

11. Electronically controlled twin tube
gas pressure dampers in the front
Along with Porsche active
suspension management
Multi link rear axle with adaptive
electro mechanical system

12. 4)BRAKE SYSTEM

13.  High-performance hybrid brake system with adaptive recuperation.
 Internally Ventilated and perforated front ceramic brake disks.

14. 5)POWER TRANSMISSION

15. WORKING
 The main source of propulsion is the 4.6 litre 608 hp(453kW) V8 engine(4,593
cc) derived directly from the power unit of the successful RS Spyder(older)
 918 Spyder power unit features dry-sump lubrication with separate oil tank
and oil exractor.

16.  Light-weight design have resulted in some features such as titanium
connecting rods, thin-wall, low-pressure casing on the crank case and
cylinder heads, light-weight steel crankshaft with 180 degrees crankpin
offset and extremely thin-walled alloy steel/nickel exhaust system.
 The V8 no longer supports any auxiliary systems, there are no external belt
drives and the engine therefore is compact.
 Weight and performance optimizations achieve a power output per litre of
approx. 133 hp/l.
 The 918 Spyder can be powered at the rear axle either individually by the
combustion engine or electric motor or via jointly both.

17. ENGINE TECHNOLOGY

18. 6)PDK DUAL CLUTCH & 7-SPEED
GEAR BOX
It has 7-Speed gear box coupled to
Porsche’s own PDK double clutch
system.

19. Principle used is overlapping transmission

20. 7)ELECTRIC MOTOR
&
GENERATOR
115kW electric motor on the rear axle.
95kW electric motor on the front axle.
Combined system power is 887 hp(661kW).

21. 8)LIQUID COOLED
Li-ion BATTERIES

22. 9)OTHER IMPORTANAT POINTS:
 To save weight,
components such as oil
tank, the air filter box
are integrated into the
subframe.
 Air induction are made
of carbon fibre
reinforced polymer.
 The tailpipes terminate
in the upper part of rear
end immediately above
the engine. No other
vehicle use this solution.
 The top pipe greatest
benefit is optimal heat
removal, because the
hot exhaust gases are
released via the shortest
possible route.

24. HOW PORSCHE 918 SPYDER IS ECO-FRIENDLY ???
 When we say extravagant car, many would definitely refer it to a racing car. However, with the popularity of
eco-friendly item, the car making industry gets highly affected and the Porsche 918 is clearly an example.
