2nd generation Harrier year 2008. And no I did not release the fuel pedal. Who will be that idiot to do so? Idling rpm with AC is 650, while rpm for cruising at 140km/h is around 1.6k. Pls note the word cruising.

Suggest u get a similar car for a test drive to find out rather than doing guessing through your own interpretation based on gear ratio.

Hmm... actually got formula to calculate the figure.

https://en.m.wikipedia.org/wiki/Lexus_RX#XU30

Kph = 110

Diff ratio = Final ratio ( 3.48 for rx350 )

Gear ratio = Last gear ratio ( 5th gear - 0.756 for rx350 u151e )

Tire diameter = Rolling diameter : W x H x Rim size ×(22/7) : ( 235 x 55 × 18 ×(22/7) = 731

So from the above calculation . The v6 engine 350g aka rx350 will be 2.1k rpm on 110kph .

Ps : please correct me if im miss something . The number is approx . Ty
