一年行車里數 與用車分析

過去一年, 原來行左40000km, 有用$1/km的MR2, MX5, 又有用$1.4/km的Coupe同Fairlady
用左$48000油錢
現在重新安排車隊, 究竟有咩可以揀呢?
買架新Abarth punto 1.4T $1/km 再慳牌費同維修, 係唔係solution呢?

所以,多一架車只係有一架spare車的方便, 慳
唔到D咩


千真咪同老婆咁樣分析, 否則以後唔使旨意有二,三,四奶玩卜

請問 SAFC 之類的可否 SET 個 Lean burnt mode 等架車慳油啲。當然,要夾番個 boost.

用左好多過往數據, 計算出
一年行40000km,
就算買架腳車,油耗只是$1/km, 同架coupe $1.5/km一齊用,
慳左的油錢係用左黎買牌費同整車換油保養洗左去.
所以, 多一架車只係有一架spare車的方便, 慳唔到D咩.
而家要嘅係好好咁去行慳油模式.

coupe?

呢個油耗問題要盡快解決, $1.4一km真係唔係辦法.

5叔定6叔現時都無得揀. 唔想要銀色, 所以而家賣緊果架6叔啡頂都唔吸引我.

I am just trying to place a quantifiable pricing differential towards the pricing between 5sp vs 6 sp on a guesstimate manner.

However on the emotional side, Simon has yet to own a 6sp car, so the head might point to 5sp, the heart will undoubtedly point to 6sp (regardless of the price differential).

The answer is on the table la.

5 spd

Can the $50k to $60k difference (if this is the case) can justify the fuel economy (0.64L/100km or 2mpg)?

Simon does 150km on a daily basis, assuming 90% of the daily trip is highway using top gear.

5sp final gearing ratio = 3.53
6sp final gearing ratio = 3.13

6sp has approx. 11.3% taller gearing than 5sp, and assuming 5sp is returning $1 per km, and further take a wild guess that the mechanical losses + extra gear weight of the 6sp gear box results in 1.3% losses, hence the net fuel saving is approx. 10%.

150km x 90% x $1 x 10% = $13.5 per day

Assuming 5 days a week, 52 weeks per year.
$13.5 x 5 x 52 = $3,510 p.a.

Assuming 3 yrs ownership
Fuel Saving = $10.5K over 3 yrs.


Further assuming a 6sp will have a $10K residual value over the 5sp model (of similar age), therefore you can consider a 6sp model with $20.5k premium over the 5sp model (base on fuel efficiency + residual value)

根據呢個car emission registration, 5速同6速油耗都係一樣.
5速and6速都係 extra-urban 5.9L/100km combined 7.4L/100km

咁又可以唸架六叔, 有新D設備, 又少D整, 又唔係蝕好多.

MRS (5 spd)                                                   MRS (6 spd)       
        Gear Ratio          Overall Ratio              Gear Ratio              Overall Ratio
1        3.17                             13.63                     3.166                      13.65
2        1.9                              8.17                     1.904                       8.21
3        1.39                              5.98                     1.392                       6.00
4        1.03                              4.43                     1.031                       4.45
5        0.82                              3.53                     0.815                       3.51
6                                                                       0.725                       3.13
             Final Drive =        4.3                     Final Drive =        4.312

1st to 5th gear for both 5 spd (9.26L/100km) & 6 spd (8.62L/100km) models are almost identical. 6th gear is for OD and fuel economy only. So both models are the same in terms of performance and 6 spd model has better fuel economy. Also 6 spd will be heavier.

Can the $50k to $60k difference (if this is the case) can justify the fuel economy (0.64L/100km or 2mpg)?

03車要11萬, 00車要68000, 相差4萬, 而油耗相差10%.
如果要慳4萬油錢, 要行足400000km!!!

另外
03車3年後會賣$68000, 估佢要$15000去整, 無左$57000
00車3年後會賣$30000, 仲用$25000去整, 唔見左$63000

似乎, 唔應該追求六叔.
