看到RAV4油電四驅的油耗破40km/L - 休旅車

台灣油耗測試就跟隨歐盟(ECE R101)

NEDC行車型態組成
4個UDC(urban driving cycle) + 1個ECDU (extra urban driving cycle)

每個UDC測試時間195秒行駛約1公里，EUDC測試時間400秒行駛約7公里

總共1180秒行駛11公里

ECE R101第2版修正
https://www.unece.org/fileadmin/DAM/trans/main/wp29/wp29regs/r101r2e.pdf

Annex 8
Method of measuring the emissions of carbon dioxide, fuel consumption and
the electric energy consumption of vehicles powered by a hybrid electric
power train

其中RAV4屬於NOVC(Not Off-Vehicle Charging)：不可插電的油電車(HEV)

6.
Not Externally Chargeable (notOVC HEV) with an operating mode switch

6.1
Emissions of carbon dioxide (CO2) and fuel consumption shall be determined
separately for the Part One (urban driving) and the Part Two (extra-urban
driving) of the specified driving cycle.
市區非市區的能耗/排放要分開

6.3.1
The test results (fuel consumption C [l/100 km] and CO2-emission M [g/km]) of
this test are corrected in function of the energy balance batt of the
vehicle’s battery.
油耗C/排放M都要經過修正

The corrected values (C0 [l/100 km] and M0 [g/km]) should correspond to a zero
energy balance (cted in function of the energy

In case of other storage systems than an electric battery, ΔEbatt is
representing ΔEstorage, the energy balance of the electric energy storage
device.

能耗需要以ΔEbatt修正，公式如下

6.3.1.1.
The electricity balance Q [Ah], measured using the procedure specified in
appendix 2 to this annex, is used as a measure of the difference in the vehicle
battery’s energy content at the end of the cycle compared to the beginning of
the cycle. The electricity balance is to be determined separately for the Part
One cycle and the Part Two cycle.



所以前面有篇回文說說充飽電再送測，還滿好笑的XD

不過即使有經過ΔEbatt修正，只要電池容量較大，市區油耗還是會相當的好

因此ΔEbatt修正後的結果並不貼近實際使用情況

要比較類似實際使用情況，可參考美國EPA(Environmental Protection Agency)的結果

市區/高速分別是41/37mpg(17.4和15.7 km/L)，與ECE的測試結果有著不小落差



結論
1. ECE油耗測試有經過ΔEbatt修正
2. 但ΔEbatt修正受到電池容量影響，與實際使用情況仍有落差
3. 比較準的能耗請參考EPA

: 我嘴裡的咖啡差點噴出來了
: 這可是加速俐落的休旅車耶...
: 2.5的排氣量
: 1755的車重
: 7秒台的0-100
: 40以上的市區油耗
