Hi

I hear the upcoming Jazz theyre hoping to get 100km from 4 litres.

That sounds like barely over 1 baht/km.

 

How much cold one save by retrofitting an older (say) Jazz, and what improvements would readers recommend?

Isn't the new Jazz coming with the new 1.0 liter turbocharged engine combined with a CVT gearbox. If this is the case, I think retrofitting that new engine with new gearbox is going to be costly and near impossible to find an engine available for purchase...

Then there is the new city with the turbo engine available already. I'd sell the old jazz and get the new one when it's here. There will also be hybrid versions of both cars at a later date. It just wouldn't be cost effective to fit the new engine (where would you get it?) and fit into the older jazz. Fitting the new engine, trans+ecu and actually getting it could run, would be just too expensive.

Guys you are forgetting we are in LOS - they day after (maybe 2) its releases some idiot will sticker it up & fail to navigate a tricky bend & write one off! 

I think one would have to do many, many kms to justify buying a car to save on fuel.  

 

Wear a right shoe one size smaller?

We recently purchased a new vehicle to replace my wife's 2012 toyota corolla. There we a lot of options and I did my research to settle on the best option,

  The hybrid option gave an incredible mpg but cost several thousands of dollars more,, after doing the math (at today's fuel prices) it would seem that the break even time, where you would start seeing a profit would be 11 years.

I am not telling you anything you don't already know, but  IMO it is worth repeating it

 Before spending money, to save money. one needs to consider if the money spend and effort , is worth the money saved.

The OP would save nothing. Retrofitting a CVT transmission would be an expensive exercise, and fraught with risk. The CVT is what gives better economy. However, I prefer the older torque converter automatics - proven reliability, and I like to be in control of what the gearbox is doing.

People don't buy hybrid versions to save money.. They do it to use less gas.  But in Thailand its stupid because they use coal for electricity.

Yes, only about 15% of the generation in Thailand is from renewables. It’s mainly gas with about 20% from coal.

 

A PHEV say the size of an MB E Class will use less than 6ltrs:100km on a long run in mixed traffic...

My 1.6l LPG costs around 1.8 baht/km. I had two but now only one. Both came with LPG from new.

Pretty poor coal at that. The Mae Moh lignite is one of the dirtiest in the world.

 

CNG sounds attractive; however, it is false economy. I was paying less than 1 baht/km on CNG with a Vios.

However, the tank has to be inspected once/year prior to renewing registration. 700 baht. In addition, cylinder head temperature with CNG is 600 C, which means the engine life becomes shorter.

I had the CNG dismantled at 100,000 km, engine is now at 155,000 km on 91 petrol. There's also the knowledge the fuel tank is far less likely to blow up on me. 2500 psi on a CNG tank does give one food for thought.
