4 1. Toyota 2050 Environmental Challenge 4 The global environment seems to be getting worse rather than better.

5 1. Toyota 2050 Environmental Challenge 5 Annual greenhouse gas emissions (Gt CO2 Eq./year) Forecast of international climate change RCP8.5 scenario (+3.7 to +4.8 ) RCP2.6 scenario (below +2 ) 40 *RCP: Representative Concentration Pathway Full-scale initiatives to reduce CO2 emissions Zero or less Source: The IPCC Working Group III 5th Assessment Report (2014) There is no time to lose for reducing Green House Gas emissions.

6 1. Toyota 2050 Environmental Challenge 6 Specific challenges that Toyota is taking on

7 1. Toyota 2050 Environmental Challenge 7 Average new vehicle CO2 (T to W) New vehicle zero CO2 emissions challenge 90% reduction % reduction in new vehicle CO2 emissions by 2050 compared to 2010.

8 1. Toyota 2050 Environmental Challenge 8 Sales volume (%) Development of next generation vehicles HVs Conventional powertrains PHVs FCVs EVs (Year) We will continue to launch more HVs, while accelerating the development of next-generation vehicle technology.

9 1. Toyota 2050 Environmental Challenge 9 Sales volume (%) Development of next generation vehicles Short to mid-term HVs Conventional powertrains PHVs FCVs EVs (Year) Short to mid term: Enhance performance of the whole lineup, from conventional vehicles to PHVs. Key role for new generation TNGA powertrains: meeting CO2 targets, while boosting vehicle appeal.

10 Contents Toyota 2050 Environmental Challenge 2. Mid term: Enhanced Environmental Performance of Conventional, HV and Plug-In HV Powertrains. 3. Summary

11 TNGA Platforms 11 TNGA Powertrains New engines New transmissions New suspensions New hybrid systems New underbody structure Improve basic performance by developing new platforms and powertrains.

12 12 Maximum engine specific output (kw / L) TNGA engines : Thermal efficiency and power 100 Toyota HVs Toyota conventional vehicles Other OEM HVs Other OEM conventional vehicles Future trend 70 TNGA 60 Conv. 50 HV Maximum engine thermal efficiency (%) Overcome trade-off between thermal efficiency and output performance.

13 13 Achieved by revising basic engine specifications Optimized bore / stroke ratio Optimum zone 1.18 to 1.21 Valve angle Increase intake flow + Efficiency & power index Tumble ratio : 1.0 1ZR NZ AR 2ZR NR KR Intensify tumble Tumble ratio : 3.2 3ZR NR Stroke/Bore ratio Basic engine specifications such as bore / stroke ratio and valve angle were optimized. Parts weight and size have been reduced.

14 14 The TNGA Powertrain achievement Economical and powerful Approx. -20% or more (with vehicle improvement) TNGA Approx. -12% Acceleration time 0-60mph (sec) Torque (Nm) CO2 (USA FTP cycle) Current Power (kw) New engine Current engine *medium class PC for USA market Engine speed (rpm) For an ever better driving feel, engine torque is improved in all range, while drastically reducing CO2.
