Have Jazz 2014, 1339cc petrol I-VTEC engine, only 45 000 km mileage, 16 alloy wheels, driving on my own on standard not hilly road. When I reach 100 kmh the revs (RPM) showing exactly 3000 (5th gear). Is that normal? I feel like the engine is too noisy and struggling much. My previous 16 y old Jazz 2005 with 1.2l engine (8 valves) with mileage 280 000 km, had revs 2700 at speed 100kmh and it felt somewhat easier to work at that speed. I am a bit worried... that I bought a car with bad engine... didnt show it to mechanic though, only bought it 5 days ago, privately.
