In Norwegian road safety and vehicle operation, how does operating the cabin air conditioning compressor affect vehicle energy consumption?
Answer and explanation
Correct answer: C. Increases consumption by 10-15% due to aerodynamic drag
- Step 1: Air conditioning compressors consume mechanical or electrical power (typically 1–3 kW), increasing fuel consumption by roughly 0.3–1.0 litre/100 km. Answer: Increases consumption by 10-15% due to aerodynamic drag. Why not the others: the alternative options do not accurately reflect vehicle safety standards, statutory requirements, or physical mechanics under Norwegian road regulations.
