Meet the US Spec, All-new, 5th Gen, 2023 Toyota Prius Hybrid

Hi All:

At least she is driving on all electric.

I completed a 500-mile loop last night for the first odometer study.

2023 Toyota Prius LE Odometer Offset

​

First though is that unlike the Prototype XLE's and Limited's w/ their 19s I was driving in Del Mar a few months back which showed 60 mph indicated at 60 mph actual, the LE and its 17s shows a 1 to 1.5 mph under report at 50 (50 mph actual = 51 to 52 mph indicated) and a 2 mph underreport at 70 mph (70 mph actual = 72 mph indicated) just like the 4th gens.

Regarding the odometer offset, that is not bad at all with 512.1 miles actually traveled (Garmin) vs 510.6 miles indicated (Prius) for a positive odometer offset of just .3%. As the 17s wear, this will come in line and even go negative at the wear bars, so it looks to be really really close. Good job Toyota.

I still have just under 1/4 of a tank and will complete its first top off sometime later today or tomorrow so I can find the aFCD offset. That will be the beginning of the real tell as to whether it was cooked, or we will be pleasantly surprised.

A few more impressions of the 23 LE vs my 21 Prime LE.

The 23's seats are definitely flatter, wider, slightly longer, and a bit more comfortable.

The 23's steering assist creates a much lighter feel than the 21.

The Garmin and its Trip Meter displays are a mandatory addition given the inability to see the Drivers Display Trip Odometer. The DTE can be seen by slanting my head to the right and seeing it around the side of the wheel. Toyota messed up the lower quarter of driver display sightline big time.

The 23s Auto High Beam works like most other Toyota's now. Turn on the lights, hit the AHB button, and it works. Flick the stalk forward to force high beams on. My 21 Prime has you turn on the lights, hit the AHB button, and flick it forward to get into AHB mode. You pull back on the stalk to flash high beams manually and it is a pull back and let go which puts you back into Auto. I like the new way better. Both Prius' AHB stay engaged through a reboot, so you only need to do this once.

Rolling over speed bumps at 1 to 2 mph in the 23 is a lot less harsh. The slightly larger diameter wheels and tires help but it goes way beyond that. Hit a speed bump at 3 to 4 mph in the 21 Prime and you think you may have knocked out alignment! The 23 is much, much softer over those.

The 23 LE is noisier than my 21 Prime. Probably due to the loss of the Acoustic glass in the front side windows.

The 23's Audio has been tuned a little better. Highs are a little clearer and there is a bit more punch on the low end. Of course, this could be because it is brand new and my 21 has 188k and thousands of hours on its audio system.

The LKA in the 23 is a dream. It drives the car down the Interstate easier without nearly the inputs as the 21s.

The RCC is even softer on the accel and there is no abrupt acceleration of 1 to 2 mph with its initiation like the 21.

At around the 5-hour mark while in the middle of nowhere KY, I received a Disconnect message on the infotainment display and lost Android Auto. I first rebooted the 23's Audio system and that only held for about a minute before losing connectivity again. I rebooted my phone and it reconnected just fine for the rest of the trip. I will be watching this, but I suspect it was my phone, not the 23 Prius given how it cured itself once I rebooted the phone.

HVAC control - No upfront only control anymore and it is hard to tell if the A/C is on or not in Auto. I have to push the A/C on and off to verify it is off from the switch controls.

Hi Edwin:

RCC since the 4th Gen Prius has been a must have edition to any vehicle now. It is not a take over and control, it is more of a guide system. If you take your hands off the wheel for over 2 to 3 seconds, the EPS does not feel your own micro-corrections, light torque of your hands resting in their position(s) on the wheel and will disable LKA while displaying a warning in the display to get your hands back on the wheel.

The new 5th gen Prius with the updated and feature rich TSS 3.0 has got this particular system dialed extremely well for the 9+ hours I was behind the wheel last night.

Hi Chris:

I have not driven our Hyundai Sonata Hybrid with RCC for a while now but have never had that happen. Yet.

Hi Trollbait:

Great overview and the systems do indeed reduce fatigue on longer drives in my years of longer drives while using them. Hyundai/Kia's and the VW/Audi/Porsche systems were at or near the best in the business until Toyota's TSS 2.0 and 2.5 arrived which set what I thought was best in class due to the light accels and decels. Toyota's TSS 3.0 has surpassed all with its very gentle and very predictable actions from both Lane Keep/Lane Trace and the RCC action.

Hi All:

2023 Toyota Prius LE Accessorizing Continues


Almost ready for action. ​

The Garmin Drive 53 is mounted and powered via 2.6 Ah Anker power core with the antenna equipped cable black Gorilla taped into a channel ahead of the front door interior edge. And it is a must have for seeing trip meters - if you care, while driving down the road and not lifting your head over the wheel all the time. The GoPro Hero9 Black is also mounted with its power cabling ran underneath the top edge of the headliner and powered via another 2.6 Ah Anker power core held within the visor organizer which is barely visible. My Galaxy S22 + is mounted in one of my standard cup holder mounts and powered with a red braided USB-C to USB-C cable to the USB-C power outlet. I do not need to use the USB-C data port since I have wireless Android Auto.

Now, where in the hell do I mount the ScanGauge III so its cabling is hidden? I may mount that ahead of the lower console tray so as to keep things tidy but if it blocks access to the tray, I may mount it ... Hmmm.

Hi All:

Putting these pics together suck as it took over 2-hours but at least it is finally complete.

2023 Toyota Prius LE Cargo Dimensions


Cargo height = 26.5 in -- Length with seats down = 62 in


Depth with seats up = 31 in and Max width = 36 in​

The next dimension is the one that really hurts however... I measured the width of my 2021 Toyota Prius Prime opening and it came in at 42.5". The 2023 Toyota Prius LE's opening width is just over 34" by comparison.

Hi Trollbait:

Here is a pic of the 23 Prius' RCC and LTA sensitivity adjustment display.

Hi All:

The 2023 Toyota Prius LE is topped off, the OEM Trip A/B are reset, and the Garmin's Trip A/B are reset for the aFCD calibration drive.

​

On a slow volume Sam's Club pump, the auto shut off arrived ~ 0.9 gallons before the full top off. It took about 20-minutes in total and the angle of the fuel port is steeper than the 4th gens making spillage less likely. That is a good thing.
