This is surprising that we don't see more of this model on the road.

So, why don't we see more of this on the road?

Surely it's not just the turbo?

I believe its probably due to branding issue. And Tan Chong isnt putting hard effort in building the brand name.
Furthermore they are already making losses.

Secondly, at RM 83,888 , and a 1.0L turbo which gives a mere 100 horses (consumers always like to look at horsepower, even though they are not racing) and some would even look at "Eh its only 1.0L displacement" typical mindset.
The previous Almera wasn't doing that well either even with the standard 1.5NA.

Its also way more expensive than City 1.5L , which starts from Rm 77,600 (and the E spec is around the corner at RM 85,800)

And the popular Proton X50 (despite different segment) is just a shy RM 86,300 onwards, which attracts customers with the 1.5L turbo, and quite good looking dashboard interior.

Required only if you have been tekan-ing... isn't it?

Nope. Applies to all cars.
My standard of practice

i) Idle the engine for 30 seconds (roughly) before putting into gear - Let the lubricant circulate properly even though I know its on 0W or 5W viscosity and it should be seconds .
ii) Then start driving. Engine oil temperature takes longer to warm up compared to your water temperature.
- I have the habit of not turning on the aircond until the water temperature reaches minimum 50C ; This is so that it doesn't place extra load during cold engine, and your radiator fan will cool it down, making it warm up slower.
- For cars without Celcius or OBD, its either the Blue light goes off or 2 bars (for my Proton) which indicates around 50C has passed.

iii) Drive gently first if possible. Not asking you to drive like a granny and hog the road. GO easy on the throttle.
- Even in F1, they heat up the engine block (without engine running) first before start of the race.

Engine oil i can say improve a lot by using fully synthetic and lower viscosity for faster oil flow & protection

But regarding turbo cooling system might need to take note on that, if your turbo engine system does not got like modern continental which got additional oil or water cooler system (some use electric water pump to keep running) to cool down the turbo after it is off it is better to idle for a while like 10~15 seconds or fit a turbo timer with oil temperature or O2 sensor reading to help prolong the turbo life.

I have owned a turbo car before. There are some precautions you need to take. But that was sometime ago.

Technology has improved. I don't believe what you are doing is necessary anymore.

Yes you are also correct ,howszat. I'm also using Full synthetic.
Its just a self-precautionary measure despite not written in the manual.

Usually I will intentionally idle the car with aircond on (depends on how long it take), to bring the shutdown temperature down to below 87C.
This is for Exora. I know other turbo cars not required due to better cooling system design (and dont have Oil Cooler Assembly)

For Exora, anything above 88C it will auto trigger the radiator fan and it takes minutes cool it down until it drops below 88C. On normal driving, it will hover between 86-88C.
Cause when engine shutdown it will rise up to 90-91C. I've monitored this through the OBD. And for Exora, it does have a separate electric water pump.

Unfortunately my usual app, is not able to read oil temperature from Exora's ECU.
@littlefire, regarding about your comment "O2 sensor reading to help prolong the turbo life"
Exora's ECU allows reading of catalytic converter temperature, but I find it useless.

Hope this explains well my precautionary measures.
