2 Infiniti JX35

3 What does the Segment look for? How does JX Win? Styling (Exterior/Interior) Seating Capacity/Room Safety Brand Experience Value for the Money

4 Unique Selling Points for JX35 USP 1 : For Family Best Space and Packaging with Style USP 2 : For MOM Multi-Tasking and Smart Driving USP 3 : For KIDS and GRAND DAD/MOM Hospitable Interior for Children and Adults

5 For Family- Interior Interior reflects Design Cues from the Award Wining Infiniti M Interior Flowing shapes, high quality Best in Class Space (Class defined as Ward s Large Luxury CUV Segment) Best in Class Total Passenger Volume (149.8 cu. Ft.) Best in Class 1 st Row Head Room and Leg Room Best in Class Cargo Space behind 2 nd Row (3 rd row seats folded flat. 2 nd row seats in forward-most slide position)

6 For Family- Exterior Grille Exterior design cues with the stunning Infiniti Essence concept Clean, not polarizing Double Wave Hood Crescent Cut D-pillar

7 For Hectic Mom Infiniti Connection Telematics Service with Infiniti Personal Assistant Google Calendar integration Drive Zone & Speed Alert World s First Backup Collision Intervention system (BCI) Next generation Around View Monitor with MOD (Moving Object Detection) Best in Class fuel economy Combined MPG (21 MPG) for FWD

8 For KIDS AND GRAND DAD/MOM 2 nd row Seat Slide Function Long slide (5.5 ) and tilt function provides class leading 3rd row Unique Child Seat Folding Seat Feature on 40% side Easy access to 3rd row without removing a child seat in 2nd row. Tri-Zone HVAC system It offers optimum comfort in each row, including 3rd row Dual DVD Theater System Rear passengers can choose individual video sources (DVD, USB, VTR Jack)

10 JX35 Development

11 New development schedule Infiniti JX was NNA s first V3-P project which is a shortened development schedule, key reductions are: Enhanced Digital phase activity by CAD data quality and CAE Physical phase schedule 19.5 month (6.5 month compressed) Previous development schedule Start 26.0 month SOP Digital Activity Prototype trial Production trial s V3P schedule for JX Digital Activity Start 19.5 month 1 st Trial Lot Production trial lot SOP 6.5 month savings

12 Nissan Integrated Manufacturing System Concept of NIMS We can build more models We can build in ANY plant Reduced development for new models NIMS Conventional assembly line Increase by > 6 Models 22% Reduction (B/Side, E/Con, PF) 4 Month Reduction Production Model Capabilities Tooling cost per additional model Timing for tooling modification

13 Strategy for Unibody vs. Frame Key Benefits of Improvement Ride & Handling NVH Body Stiffness Mass Reduction Fuel Economy

14 D-Platform Strategy (common D-Platform design) Improved Roominess and 3 rd row seat ingress/egress All new Platform for JX35

15 JX35 Torsion Targets Rear Torsion requires a higher target to make up for reductions in other systems: Tire width decrease for fuel economy improvement Mass reduction JX35 Competitor #3

16 JX35 Torsion Targets Several iterations of CAE were run to fine tune stiffness and increase mass reduction. Critical parts for Body stiffness are: Red = Primary Orange = Secondary

17 Design Challenges

18 Design Challenges JX35 Design Conventional Design Blue Pathfinder RR Roof Section 40mm of headroom improvement Orange JX35 Section Hinge was moved to improve head room

19 Design Challenges Deep clearance pocket was required to eliminate Styling bump at Hinge area. This reduced section caused larger stress issues than expected in the digital phase Details on next slide

20 Design Challenges UPR D-PLR HAS THICKER PARTS AND LESS REINFORCMENTS. ROOF DITCH HINGE LOCATION Hinge Loading

21 Material Usage BIW UHSS utilization: High strength with reduced weight High strength performance Roof Crush Front Crash Side Impact Material Utilization Upper Body Utilization 35% UHSS by mass Platform 39% UHSS by mass

22 Safety Roof Crush

23 IMPACT SAFETY (Roof Crush) The upper body construction minimizes the intrusion into the occupant compartment through the application of high strength steels. - Roof strength achievement with smaller section sizes to meet visibility and roominess targets.

24 IMPACT SAFETY (Roof Crush)

25 IMPACT SAFETY (Roof Crush) UHSS application and optimization: - 8.8kg mass savings in upper body - Approx. 20% performance improvement Baseline Final

26 Safety Rear Impact

27 IMPACT SAFETY (Rear Impact)

28 Safety Side Impact

29 <Key points for side impact> IMPACT SAFETY (Side Impact) <Body Structure> Designed to maintain integrity of the cabin in the event of a side collision by use of Multi-Load Path impact force dispersion structure and use of high strength steel. <Restraints> Side airbag Energy absorption airbags with separate chambers for chest/abdomen and pelvis areas allows for occupant injury reduction. Inflatable Curtain Occupants of all 3 rows are protected by the inflatable curtain airbags. <The Merit to Users> Safety Zone Body structure and efficient restraint systems allow for improved Safety performance.

30 IMPACT SAFETY (Side Impact)

31 IMPACT SAFETY (Side Impact) <Impact Force Dispersive Side Body Structure> Multi-Load Path Structure Side SILL reinforcement for dispersion to front and rear cabin

32 Safety Front Impact

33 IMPACT SAFETY (Front Impact) <Key points for frontal crash> <Body Structure> Crushable zone Efficient Energy absorption side member structure was achieved with the use of high strength steel. Safety zone Designed to maintain its integrity in the event of a front collision by use of Multi- Load Path impact force dispersion and use of high strength steel. <Restraints> Seatbelts Pre-tensioner & load limiter are equipped for driver & passenger as Standard. Front Airbags SRS airbags are equipped for driver & passenger as Standard. <The Merit to Users> Body structure crushable zone & safety zone with efficient restraint systems allow for improved Safety performance.

34 IMPACT SAFETY (Front Impact) <Key Points for JX35 Frontal Crash Body Structure > Front pillar Multi-Load Path for Impact Force Dispersion Front Side Member Side Sill Crushable Zone: Crash energy management zone designed to absorb the energy generated upon impact. Safety Zone: Rigid zone designed to maintain its integrity with minimal deformation to protect the occupants and the fuel tank.
