Toyota Prius Alpha/Plus

[Joeleekw]

I just did my servicing, still no auto lock to be installed. Think need more to pple to feedback then Borneo will do something to it.

[Lava]

is it the model that used widely by phv and taxi?

In the absence of RPM Gauge or electronic Scan Gauge, the PSD simulator can be a source to verifying. Get the page (link) to work and play with the level and you will see at 110 km/h, the rpm can be from 4000+ rpm (maximum power, most noisy) to 1200 rpm (light load/resistance cruising, quietest).

have drove axio 1.5 hybrid during holiday covering ~500km range with refuel to full 22L.

route include city, highway, hill climbs and etc.

2 adult 1 child + 50kg luggage weight.

 

the rpm does range from as low as 1000rpm to 4000rpm depending on load demand and speed.

this can be seen from the tachometer.

it's weird such entry level axio model do come with tachometer however higher model like chr, Camry, Prius come without tachometer.

Hi guys,

What car steering wheel lock you get for your Prius +?

thought of getting one before heading to Malaysia.

Thanks in adv

Quite awhile... think the FC is improving as the hybrid gears are being smoothen and the right foot is becoming lighter :)

 

If you are not hurry, left lane and light foot help...

 

Always top up at the last 2 bars...

 

27th tank... 

 

I thought this is an achievement by my cabby friend laughs... Anyone did better?

My last 2 cars did not come with the auto-lock feature we used to have.

 

I was told that the feature though sensible but carries a risk for both occupants and car manufacturers.  The question was: Why if the doors were auto-locked and in a collision, the supposedly feature to automatically unlock all doors failed?  The first to get hit will be the car makers but since it is now MANUAL, the onus is on the driver or occupants themselves.

Hi ChonSiew,

i dont understand the following, need to consult you for technical sharing

Normal petrol cars that stop their engines at traffic lights will give a jerk when the car restart

while Prius dont feel the jerk (not as obvious ) when we switch between electric and petrol.

Stepping in.  The Prius and other toyota hybrids do not use conventional transmission like standard auto/dual clutch auto transmissions.  Instead, Toyota created an efficient and complex planetary gear transmission that merges the power of both the electric motor and petrol engine seamlessly.

 

This video explains how Toyota implements it (Gen 3 example, like the Prius Alpha) https://www.youtube.com/watch?v=HvnzKD5xPbY

 

This explains how the planetary gear works to combine the power of the electric motor and the petrol motor seamlessly. https://www.youtube.com/watch?v=ARd-Om2VyiE

 

And this describes the exact implementation in the Gen4 https://www.youtube.com/watch?v=vHc-_E8xWnM

normal auto with torque converter.

you remain in D, when engine start back the fluid in torque converter spin again cause sudden peak torque = jerk.

 

Toyota hybrid no torque converter

and the engagement of engine clutch to power split unit is very well refined. that's the strength of Toyota hybrid system.

Thanks Contipro and Nostalgia!

will check out the video tonight!

Thanks to Contipro and Nostalgia, and that's about the answers.  One more technicality we need to know is that there is no starter motor for Toyota Hybrids.  In non-hybrid cars, the strong jerk when ICE comes alive attributed to the cranking of starter motor, the re-ignition of ICE and as explained, the immediate torque transmitted to the drive gears.

Hi, I'm considering Prius+ Hybrid and Outlander, I will drive to Malaysia twice a month. May I know how does Prius+ Hybrid perform in highway? I saw the specs, the power and torque is it enough? I know it's a family car not sports car but sometimes need to take over car in highway. Currently driving HRV

Personally have driven on NSHW a couple of times to and fro Melaka. With Power mode, it wouldn't be a problem.

How is this car? Any comments?

[chonsiew]

Just done my 30K servicing and wish to report that the car holds very well structurally.  Nothing has come loose despite 30Km over many bumpy dig&patch dig&patch SG road.  The numbers of roadwork that dug up the road are really drove me crazy!!

 

The hybrid system aged very well too, with returns edging up between 22 - 28 kml and not less than 20 kml for city+urban.The hybrid gears seems well rounded (seasoned) too and the transition of power between EV and ICE is getting smoother by the days. You actually love the feel while the heavy wagon is pulled effortlessly with hybrid power. 

 

Sharing:

 

1.   The difference between Normal (ECO) and Power (PWR) are the gears ratios driven by a set of fuzzy logic managed by the drive computer.  When you switch to PWR, The computer thinks you are in a hurry and switch EV & ICE reduction gears lower to anticipate.  on touching the accelerator, the higher torque output pulls the car takes off very quickly. These PWR combined output remain in anticipation even you start to slow down or stopped.  Some drivers love to drive in this mode (with anticipating surge power whenever you want).  The downside is higher FC but Shiok!

 

2.   I preferred ECO mode, petrol price is getting higher by the day (glad I have the hybrid)... In this mode, the fuzzy logic senses that you are not in hurry and no major event is expecting (challenging the guy beside you for example), so the reduction gears for both Electric and ICE are set higher. When you touch the pedal not too heavily, the EV (Electric drive only) mode will slowly pull the car and its reduction gears will switch to higher ratio (Tips): By easing off on the pedal once the car is in motion will trick the EV gear to switch higher (think the load has been reduced) and when you depress the pedal gentlely again, You actually can feel the EV is being geared higher.  With speed gradually increased, you can repeat the ease back on the pedal and EV can be achieved and maintained up to 72 kmh (I got this most of the time at KPE). Of course, that depend on the hybrid battery SOC.

 

3.   Highway overtaking: Switch to PWR will feel the car being tightened in anticipation for a race.  Some may be laughing but do it correctly, Toyota hybrid can be a force to be reckoned with and you don't lose many traffic jumps with PWR!

Hi , So fast reached 30K,how long have you been driving this car? I guess you own this less than 1 year Right.

Hello, which button to press to see the last pic ah? I’m trying to see my fuel consumption for total mileage, but I manage to see only “current trip”, “current tank” (I use trip a), and trip b

 

Also, is there a way to change how fuel consumption is shown? My current display is x.y liter per 100 km. How to change to show like yours, ie 1 liter = x.y km?
