How to define Micro-Van and Micro-Truck? Height of R-point≥800mm Rear axle drive Mid-engine: Center of gravity of engine is between the front and rear axles, and the longitudinal distance from center of front axle to center of gravity of engine≥300mm. GVM ≤ 2.5 ton 4

Market share of Micro-Van and Mirco-Truck in China(2013) Total sales of vehicles: 22 million, M1 and N1: 20 million, Micro-Van and Mirco-Truck: 2.2 million 5 MPV Sedan SUV

Chinese micro-vehicles are not designed or planned for sales in Europe, Japan or US. ECE R94 Frontal impact R 127 Pedestrian Protection ECE R13H Braking system ABS ESC BA 661/2009/EC TPMS 443/2009/EU (M1) 510/2011/EU (N1) CO2 emission  The requirements of ECE, FMVSS and EPA regulations (R13H, R127, R94, FMVSS 208, EPA Tier II, etc.) are too difficult for Micro-Van and Micro-Truck. 8 Without Steering booster R48 Day-time running lamp R116 Engine Theft Protection

* Over 2,180,000 Micro-Vans and Micro-Trucks were sold in 2013 globally, within this nearly 95% were sold in China, and others were sold into other Third World in Africa, South America and South East Asia. Europe, Japan and US are not our target markets. * Although Micro-vehicles are very inexpensive and with poor performance, also will not be accepted by the customers in Europe, Japan, or US, it’s really an important type of vehicle for developing areas and developing countries. Global market of Micro-Van and Micro-Truck (2013) 9 China 94.9 % South America 2.1% Africa 2.4% Southeast Asia 0.6%

10 Micro-Van and Micro-Truck are typically 2 to 3 dB(A) higher than front engine type.  Micro-Van & Micro-Truck need the 74 dB(A) limit value for phase 1 like heavy M dB Separation

Micro-Van and Micro-Truck noise sources are much more exposed than front engine type GVM ≤ 2.5 ton R-point ≥800mm from the ground Mid-engine and with rear axle drive Same type Front Engine type GVM≤2.5t Different type R≥ 800mm R ﹤ 800mm 11

Micro-Van and Micro-Truck noise sources are much more exposed than front engine type Engine Gear box Shaft Final Drive and drive axle Exhausted pipe Muffler The majority of noise sources in Micro-Van and Micro-Truck are directly exposed, resulting in inherently louder noise. 12 Floor

Difficulty of adding noise shield for Micro-Van and Micro-Truck * There is no engine-compartment for Micro-Van and Micro-Truck, and it’s impossible to cover the whole powertrain system for the purpose of reducing noise, as what front engine type does. Front engine type Micro-Van and Micro -Truck The ground clearance is about mm, adding noise shield will reduce ground clearance by 10mm, resulting in poor passing capacity. 13 * Adding Noise shield will greatly reduce ground clearance, key characteristic for Micro-Van and Micro-Truck used in mountain, farm, and rural areas. The ground clearance and passing capacity are very important for Micro-vehicles used in mountain, farm, and rural areas.

Difficulty of adding noise shield for Micro-Van and Micro-Truck * The thermal performance of Micro-Van and Micro-Truck is not as good as front type for the reason of structure and powertrain differences, and adding noise shield will greatly reduce thermal performance. 14

Limit value table for special M1 / N1 category Sub-categoryFigure Country of Origin China suggestion (GRB-55-05, GRB-56-07, GRB 57-05, GRB-58-09, GRB-59-04) Limit value now (GRB/2014/5) Ok? Heavy M1GlobalSupport GRB74Ok Micro-Van Micro-truck China7472NG Kei-truckJapanSupport GRB74Ok “GRB-59-04” For vehicle types of category M1 and N1 having a maximum technically permissible laden mass of less than or equal to 2.5 tons, a R-point height greater than 800mm from the ground and a mid engine with the longitudinal distance from center of front axle to center of gravity of engine≥300mm and with rear axle drive, the limits of the vehicle types of category N1 having a maximum technically permissible laden mass above 2.5 tons apply. 15

Conclusion  The structure and powertrain system of Micro-Vans and Micro- Trucks are quite different from the front-engine type vehicles, which will lead to a 2-3dB(A) higher test results according to ECE R51 / 03.  The Micro-Van and Micro-Truck need a 74dB(A) limit values for phase 1 st with a cut-off nearly 15-20%.  China suggests modify “GRB For vehicle types of category M1 and N1 having a maximum technically permissible laden mass of less than or equal to 2.5 tons, a R-point height greater than 800mm from the ground and a mid engine with the longitudinal distance from center of front axle to center of gravity of engine≥300mm and with rear axle drive, the limits of the vehicle types of category N1 having a maximum technically permissible laden mass above 2.5 tons apply.” 16
