and your situation does not apply to other forte owners.
don't mislead others.

my mistake....hehehehe

Sorry bro, i dont get it either. Both rims are the same in term of size (diameter) & using back the same tyres (i presume u did not do tyre rotation also), but the speedo gives significantly different speed reading..how come? Rotational speed (of the tyre&rim) are related to its radius (or diameter) right? Since there's no change in diameter for both rims (14" in this case), the speedo should recorded the same speed reading for both rims also (provided the same tyres are installed back at the same position as it was on the previous rims + same tyre pressure for both 'experiment'). That's why i failed to understand your above statement (different speed readings). I dont think the different in rim materials will affect the speed reading. Now your data collecting methods & procedures (comparing speedo & GPS speed readings) are highly questionable...Again, no offence...

Other experts here please shed some light for third party confirmation (did not want my comment to mislead others if i'm wrong). TQ

the correct way to measure is by stick at 100KM/H at speedometer and observe the GPS reading. Since GPS give reading in digital.

or does your SEG come with digital meter / aftermarket meter?

and izputra is correct. speedometer is affected by diameter of the rim.

+++1..!!

physics never cease to amaze me

just past through proton showroom....i prefer forte more than inspira...inspria feel so plastic...

but its handling is superb!

damn right its plastiky especially the dashboard, its just too squarish. right away i saw the interior..no comment.

Yes. Jalan Lahat. They got stock but just try ur luck...

Anyway, different people different mindset. My whole family prefers TaHaN for their resale value and local-easily-find-spare&mod-parts.
But if really go for depreciation calculation, i think Forte really worth the price. Open market value might be lower, but just imagine u are sitting in a car with same segment & standard with honda civic with price that's lower than a honda city. Sell away a honda civic 1.8 5 years later with its interest add-on, at least lose 60k, forte? We already saved in new car price and the interest paid. It might only be able to sell away in a very low price but at least lost lesser than a civic. And again, both car are the same C-segment car. I dun think forte lose civic much. For me, resale value is just for those fully paid owner. I pay 9 years installment, no point to think RV as long as low car price, & interest rate. My friend got a City 9 years installment wiht rate 3.9% but mine only 3%. Overall, even i lose much money, i owned a C-segment car. His only B-segment car nia.. And that's y my eye-ing is different with my family. Inspira looks like lancer but it's still a protong. High interest rate, i bet it need repair like any other protongs too for our local talent built up. So no matter how it looks like a lancer, log card still stated protong car. No point. I dun like copycat. wakaka.. Forte still my prior..
Cheers...

erm...if you feel the cruze is reluctant to move, the 1.6 Forte wont be any different...

2.0 for more acceleration on the go. i am inclined to believe the FC is better overall for 2.0 if you drive in mixed condition. similar comparison has been done in the past for models offered in both 1.6 vs 1.8, 2.0 vs 2.4 etc etc. power to weight ratio affects driving impression. in this case, the Forte is infact a solidly C-segment car being pulled by a "just enough" 1.6cc gamma engine. it's not bad, but less fun,

if you want fast overtaking action, a bigger cc is more appropriate.

Wei there's not much in physics leh, just simple mathematics....



If you want to do some more complicated calculations to stimulate your brain , you can calculate the relationship between the RPM of your engine vs speed of the wheels....

To get the RPM of the wheels, I think you can get that by dividing the RPM of the engine with the total gear ratio (Ratio of gear you are on * Final Reduction). Then convert the RPM into speed by changing into radians per second multiplied by the circumference of the wheels.

Since the final gear ratio is normally quite high, it means the engine RPM will be higher than the wheel RPM...

for anyone wanting to confirm change of rim size affecting speedo reading, you can check with this.

http://www.miata.net/garage/tirecalc.html

i downsized & upwidth my stock tyres, so i can vouch for a very slight (very minimal, non issue) speed misreading but with better stability whilst getting a little better FC. but of coz, only if you dont mind smaller rims & thicker tyres,

yup, with the higher interest rate for Proton, the overall ownership cost for Inspira is higher than owning a Forte!

Poison! Modulo spoiler on a Forte! Please don't quote the whole Fucuking picture

How about those 7" height spoiler like subaru & civic? Hardly see otr..

can't agree more on this statement... another good example would be a 1.6 vs 1.8 altis...fuel consumption is much much better for the 1.8 vs the 1.6 due to the power to weight ratio =)

7" looks fugly to me.. Like you want to sidai pakaian

its practical during raining days!

i dunno....mayb old car, ECU reading gt problem
wat bt weight?? alloy vs. steel....i think that also gave big difference leh....

btw, there's a naza acc. shop in alor setar. yesterday i asked, hw much cost the 'K' logo for front and back...they said RM180, and i was juz like WTF!!!! damn expensive!!!!
and does anyone knws where 2 make custom car stickers?? put own design n name 1....muz b heat+waterproof...if can, i like glow type..
can anyone help me find the sticker?

lol even the KIA emblem (the ori 'brand name') is only selling at RM90
