Toyota Prius Alpha/Plus

[chonsiew]

Hi guys,

For Prius Plus, may i know which petrol u guys using?

any difference between different company and octane

Thanks

SPC 95 all the way.  Don't waste money on higher octane fuels as the compression of Toyota's Atkinson engine is electronically-controlled and engine knocking is almost non-existence.  And since Prius+ max rpm is also capped at 4000 rpm to sync with the traction motors, higher octane fuels add no advantages.

Thanks ChonSiew!

Btw, for the first 1k service, how does it work? around 950km make appointment and faster change the engine oil before it hit 1K?

Stay within the allowable range of 999 km.  For examples, do not exceed 1999 km for the 1-Km Service or, 10,999 km for the 10-Km Service.  No repair services normally with 2 hours.

Hi Prius + owners,

I collected car and driving around 4.4L / 100km for a few days

Anybody drove to Malaysia, mileage is better?

My experience is Nope.  Prius is good for start-stops traffics like in SG roads.  But if you get out of the highway and choose Malaysia's trunk roads,  the saving is very significant for speed that is around 70 - 90 km/h.

Hi ChonSiew,

Thanks for sharing!

You have very good knowledge of Prius Plus!

I was told to stay within 2k RPM during run-in but I cant find the tachometer option

No lah, just share those things I learned from my taxi Prius friends.  Good to see lots of Prius+ or Alpha on our roads and that could mean good tech and spares support by more players - for us!

 

Good question on the techo!  And there is no way to tell the rpm until you have the diagnostics machine or some reading gauges that can plug into the car diagnostic port.  Otherwise, you will have to use your ears or feeling. Haha!

 

At stop, the rpm is either 0 or ~1300 if hybrid battery is running low (do remember a lot of things need battery power: water pump, coolant circulation, aircond, your apple airplay HU and DLR lights etc..).

 

During cruising, the Prius+ rpm can be as low as 870 and max at 4000 depends on load and driver's demand. If you drive gently and that mean allowing the traction motors to do most of the wheel turnings, the rpm is between 0 to 1500 for speed between 70 - 90 km/h.  At these cruising speed, you normally don't hear engine noise.  In Malaysia highway at 110 km/h, the engine rpm is about 2100 - 2200.  The traction motors (EV mode) always try to come in to provide additional torque to lower the rpm and that's the reason Prius save fuel.

 

In short, as long as you don't make or hear engine roar, the rpm is usually below 2000.

Is no one concerned that the Prius+ is already an outdated model having launched in 2011? It is based on the previous generation Prius which is why the interior already looks so outdated! It might be new in SG but it is already an old model.. Wonder why SG always gets either the low specced cars or old models. In fact, the Prius V was discontinued in US in 2017.

The 2019 Prius V (known here as Prius+) based on TNGA platform has already been seen undergoing testing. Personally, I would take a wait and see approach first.. wouldn't want to buy an outdated model

Concerned obviously but not anymore after a 10000 km since I have the car.

 

It really depend on you.  Your concern is on the look and feel or a practicality and dependability.  That's beside the reality of ownership and running cost.  Yes, I would like the Prius+ to be more SUV-like with all the modern amenities thrown in but I may not want to sacrifice on the already high ownership and running cost with the 2019 Prius+ (known to be SUV-like but in reality, a higher seating taller wagon. All of which would increased FC with the expected bigger wheels, bigger engine and body).

 

I thought hard and look hard at the realities - Petrol cost, maintenance cost and the purposes of owning the Prius+ 

Well, the Prius+ will not win any contest in look but it delivered what I wanted - Economy and dependability for a basic wagon.  Hope she stays that way like my Old Faithful.

Which PI?

Vince car. In the end I sign with AD

Signed with Borneo motor yesterday. Expected car delivery end Dec - jan. depending on next week COE.

I thought toyota hybrid Atkinson cycle engine is design for run at higher rpm only.

which unlikely to active at Low 870rpm.

so low speed is handle by electric motor, then when speed pick up only engine kick in at optimum operating engine rpm to maximize fuel economy.

please correct me if I have misunderstanding this..

For me I am not concerned. The car meets my needs and I need a car, I would just buy it. Plus it is proven technology that works.

Congrats for getting a much cheaper but as economical car as mines!  Care to share how much you paid and goodies you are given?

I paid S$114.900 in May!!

 

But I never have a hint of regret though :)

Unlike conventional otto cycle engines (with equal compression and expansion stroke), the HSD engine has a great challenge to balance the Atkinson cycles at higher rpm because of the unequal compression and expansion stroke.  That's why the engine doesn't sound smooth or refine when the rpm goes up.  Since HSD is designed to utilise electric motors to supplement torque across the rpm range, there is no need to have high rpm as the traction motors get more powerful.

 

For the Prius wagon, the traction motors are rated at 60-Kw and that is 10 Kw higher than the standard Prius (taxi model), Toyota engineers capped the 1.8 Atkinson engine to 4000 rpm for maximum hybrid efficiency and smoother delivery of power at varying speeds and loading.  

 

When the low rpm comes in?  

It only need a very small power or torque to run a Prius over a smooth and level surface say at 70 km/h.  At this speed, the 60-Kw traction motors are more than happy to take over the running, drawing electricity from the hybrid battery.  But what happen when the SoC of the battery runs low?  The next thing you know the engine start running to charge the battery and at the same time, power the wheel, relieving the traction motors for a quicker charge for the hybrid battery.  If the road dynamics do not change (remains smooth and level), the engine rpm is about 800 - 900 rpm, smooth and silent :)

 

Hybrid Synergy Drive (HSD) is interesting!

Driving Prius+ or any Prius if that matter, is really a personal choice. Again, I am not here to promote Prius but like to share the benefits and technological aspects of the Toyota Hybrid.

 

Just came back from another trip to Genting. The upward climbs averaged 5.7L/100km and the downhill runs, 3.9L/100km. During the downhill, the battery was fully charged to 10 Bars very quickly (the first time I achieved that) and understandbly, no battery power was needed for the that downhill portion. With this note, I agree the hybrid battery capacity should be higher to store the excess!

 

Expressway runs:

- At 90km/h (cruise controlled most of the time), it was 4.8L/100km (Sweet Spot)

- At 110km/h, it was 5.5L/100km.

Hi, what is the maximum speed that this car can cruise comfortably on the NSHW?

 

Can it cruise 150-160km/hr?

 

I am not a crazy speedster but as i have to do frequent day-trip to KL, going too slow is too tiring and dangerous for me.

I always push my car to the published max just for "acceptance". Prior to my last car Qashqai 1.2T was Touran@213, Qashqai@187 and Prius+@167 quite easily.  Seemed can go higher but was enough to accept.

 

Note: Based on surface condition, load and gradient of the road, the car's eCVT can achieve "varying max speed".

I saw your reply that u drive in malaysia around 150km/h,  can u still do the glide and use electric motor to save fuel?

Does the Prius + feel light ?

[cabriole]

Hi Prius + owners,

anybody bought car mat ?

i got one custom made and saw that the second row mat will cover the vents and i think we should not cover the the vents. anybody got experience to share?

Thanks
