Overall Energy Situation Energy conservation and environmental protection pressure is relatively high, and China s outer dependency for oil rises to 67.4% in 2017, higher than the guard line 50%. 70.0% 65.4% 60.6% 59.6% 58.1% 58.0% 56.5% 60.0% 53.7% 52.0% 49.8% 50.0% 40.0% 2017 inventory hits 30.0% Market vehicles million units of 20.0% 217 10.0% 8.14% 7.92% 5.21% 4.42% 3.27% 2.65% 2.58% 1.68% 0.17% 0.0% 2008 2009 2010 2011 2012 2013 2014 2015 2016 Vehicles with GVW more than 3.5 ton takes up nearly 10%. As high fuel consumption and long annual distance, HDV nearly consumed half of total oil consumption of all vehicles. 5
Overall The Guidance document Medium and Long Term Development Plan(2017) The average fuel consumption for new PCs need to reach the target of 5.0L/100km, CVs approach the international advanced level by 2020 NEVs energy consumption reach international advanced level The average fuel consumption for new PCs need to reach the target of 4.0L/100km, CVs reach the international advanced level by 2020 NEVs energy consumption reach international leading level 6

Status Quo Overall progress Establishing and Implement status in China 2008~ 2010 Items 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021 Establishing Issued in 2011 Test method FC limits (the 1st stage ) Establishing Issued in 2011 FC limits (the 2nd stage ) Establishing Issued in 2014 FC limits (the 3rd stage ) Establishing Issued in 2018 Establishing Implement of vehicle type under producing Implement of new vehicle type 8
Status Quo Vehicle types Apply to vehicles with GVW above 3.5t (except special work vehicle) Industry standard the first stage National standard the second stage Vehicle type Truck Bus Semi-trailer tractor City bus Dumper Special transport vehicle Special work vehicle 9
Status Quo Current test methods FC of HDVS Basic types Variant types Coastdown data or recommended values Engine data Chassis dyno tests Simulation C-WTVC City, rural and highway FC Weighted factors Combined FC 10
Status Quo Current test methods FC of basic types and HEVs could be tested according to chassis dyna testing. FC of variant types could be calculated. Based on the engine data, FC is calculated by inputting resistance and other parameters. Page11
Status Quo Driving Cycle C-WTVC driving cycle, adjusted velocity and acceleration based on WTVC . [b] Weighted factors were determined based on survey data.

Status Quo Phase 3 limits In Feb. 2018, the SAC issued the GB 30510-2018 Fuel consumption limits for heavy-duty commercial vehicles (Phase 3) China proposes that fuel consumption of HDVs will approach the international advanced level by 2020 Feasibility analysis Energy-saving target in 2020 Regulation comparison with US, EU and Japan. Energy saving technology potential analysis Test methods comparison and conversion Energy saving technology costs analysis 13
Status Quo Phase 3 limits The evaluation system is consistent with the Phase 2 limits: the L/100km is taken as the evaluation unit, the fuel consumption limits are determined by different groups based on the GVW. Units Basic parameters System Limits forms Limits for single vehicle types L/100km Stepped limits GVW Corporate averaging L/1000(km t) Linear limits L/1000(km persons) 14
Status Quo Phase 3 limits Trucks (for example) The limits decline 11.5~15.4% to the phase 2 limits. 5.0~16.8% (avg. 9.5%) of current vehicle types can meet the limits. 13.0 14.0 16.0 19.0 21.5 25.0 28.0 31.5 37.5 43.0 45.5 11.5 a 12.2 a 13.8 a 16.3 a 18.3 a 21.3 a 24.0 -14.3% 27.0 -14.3% 32.5 -13.3% 37.5 -12.8% 38.5 -15.4% -11.5% -12.9% -13.8% -14.2% -14.9% -14.8% 3 500 GVW 4 500 4 500 GVW 5 500 5 500 GVW 7 000 7 000 GVW 8 500 8 500 GVW 10 500 10 500 GVW 12 500 12 500 GVW 16 000 16 000 GVW 20 000 20 000 GVW 25 000 25 000 GVW 31 000 31 000 GVW a 1.2 15
Future Work China Cycle(CATC) CATC was issued by MIIT and co-managed by MIIT and other 4 departments. CATARC was entrusted to organize specialists for a three- year deep research. The project investment is closed to 100 million RMB and collected driving data over 50 million km. 1 The driving cycle in current standard is inconsistence with the characteristics of the actual driving condition in China and the differences become larger and larger. 2 Current regulations can t accurately evaluate new technology, such like technologies for new energy vehicle . 2015 2015 2016 2016 2017 2017 Q2 Q2 Q3 Q3 Q4 Q4 Q1 Q1 Q2 Q2 Q3 Q3 Q4 Q4 Q1 Q1 Q2 Q2 Q3 Q3 Q4 Q4 CATC CATC 1 1 3 There are increasingly loud calls for developing China test driving cycle. 2 2 3 3 16
