cool... would be interesting to also fix a constant speed, say 120 kmh for the final gear, then work backwards to see engine speed... with this can check where it sits on the torque and power curves

also another good speed to test is 70 kmh... why 70?...because some automatics with 8/9 gears will downshift from overdrive and run on gear 7 or 6... this will burn more fuel compared to lower powered car running on overdrive... lol

He might refer to your info in the spreadsheet, not the spreadsheet layout lor.

That one covered in high school physics, and kemahiran hidup, maybe back in my old days.

lol, I'm lazy. I give you the formula you make one want or not?

nah...was for you to find out if interested... I know already for my cars

Yes ive tried once. on the Sban-PD highway.
Because the road is empty, decided to see how fast the Axia can go. About 140.
The feeling of adrenaline and plus the tune of 3 cylinder engine revving almos like a in-line 6.
Ego also. Small car able to bully bigger size cars.
Because kena before bigger car bully small car.

But i dont recommend on a stock 14" tyres. And yes, after speeding sure 1 bar of fuel level drop.
So yes, i know how it feels.
Besides i myself dont drive extremely fast in this compact car.

I jam save more fuel lol

Your car supposed be on track lol.

1) Model : 2016 Axia SE Auto
2) Petrol Used : Petronas 95
3) Engine Oil Used : Perodua 0w-20


Long Distance
4) Fuel Consumption (in the meter) : 15km/l
4) Fuel Consumption (self measured) : 18.5km/l
5) Driving Condition : 50% highway 50% coastal road. No traffic. 1 extra passenger, +80kg. Half the drive was without aircond
6) Average Speed: 80-85km/h
7) Mileage : ~220km
8) Modification : None

Update
4) Fuel Consumption (in the meter) : 11.4km/l
4) Fuel Consumption (self measured) : 12.18km/l
5) Driving Condition : 100% urban within Subang Jaya
6) Average Speed: 30km/h
7) Mileage : ~284km
8) Modification : None

City drive FC surprisingly not that different compared to my old Persona 1.6.

I also feel something's not right with the FC.
Moreover I almost never used the aircond, no passengers, and tires are pumped to specified pressure.

Exactly my thoughts. My 2016 Axia E spec (Manual) does 16KM/L , sometimes 15Km/L if I drive hard and speeding. Mix city drive + highway. And with aircond.
Yes I know mine is manual, so your auto should get around 14KM/L on mix driving.

I noticed sometimes Petronas sometimes give poorer FC thats why I try reduce using Petronas.

Mine isnt mixed, its full urban.

Car type : Proton Inspira 1.8MT 2014
Driving Condition : Highway 60% + City 40%

My fuel consumption is tracked since I got the car till now.
My Fuelly Record

Doesn't look so bad for a car that people always call as a gas guzzler kuat telan minyak.

Suprise to know inspira had high fc.

Better than my ex proton persona elegance 1.6AT.

Car Type : Proton Saga BLM 1.3 (5MT)
Driving Condition : Highway 95% + City 5%
Petrol Used : Petronas 95
Fuel Consumption (self measured) : 9.5km/L or 10.5L/100km
Average Speed : 120km/h
Top Cruising speed : 160km/h
Mileage : 38X'XXX km
Mileage / year : 45'000 km
Engine Modification : None, NEW Intake air filter every 5000km.


Car Type : VW Passat B8 2.0HL (6DCT)
Driving Condition : Highway 80% + City 20%
Petrol Used : Petronas 95
Fuel Consumption (self measured) : 9.5km/L or 10.5L/100km
Average Speed : 130km/h
Top Cruising speed : 170km/h
Mileage : 10'XXX km
Mileage / year : ?????
Engine Modification : None, NEW Intake air filter every 10'000km.

Both same driving style (up to capability of engine) =D

Says a LOT about the fuel economy of large modern turbo engines coupled with DCTs.

By right your Passat should be doing slightly better than 10.5L/100km due to bigger engine and higher gear ratio = Lower Rpm / More relaxed engine .
After all it was designed for the autobahn.

Just for comparison my Exora when doing 130 constantly it does around 9.xL/100km , close to 10L.

As for your saga, well the older Campro engine wasnt designed to be fuel efficient even with the IAFM add on which only mask the torque problem.
Newer VVT protons are much more fuel efficient.

it's not as simple as modern turbo + dct... it's all about matching engine power/torque with good gear ratios for the weight+load of the car

I drove a 3.5L NA, normal 6 speed auto, 2000kg 8 seater once, and it does better than your 9.5km/l...
