This RX350h is my MIL’s new daily driver. The vehicle replaced her 2013 ES350 which has been passed along to my FIL.

I picked up the RX350h from a Southern CA dealer and racked up 550 miles before handing it off to my MIL. She has since driven another 450 miles; we’re currently at 1000 miles and I just performed the break-in oil change today.

Dimensionally, the RX350h slots between the RAV4 and the Highlander, but is closer to a RAV4. Fortunately or unfortunately, Toyota’s decision to use one global platform (TNGA-K) for their midsize CUV’s and Sedans has really closed the gap between the Toyota and Lexus lines – the Lexus vehicles simply aren’t a significant upgrade anymore. I am finding the RX350h to be a slightly more polished RAV4 – but the difference isn’t as drastic as one would expect.

The hybrid powertrain is shared with the RAV4, Highlander, Grand Highlander, Sienna, NX and TX. On paper, this new 4-cyl hybrid powertrain is quicker and more efficient than the last-generation RX’s V6 Hybrid, but it just doesn’t sound as nice. The EPA rating is 37/34/36, and for the Lexus applications, premium is recommended but not required. In the 550 miles I drove it, I had a tank of 35 mpg (heavy traffic) and a tank of 32 mpg (pure highway). For my MIL, who has only driven V6 cars for the last 20 years, it has been a tank of 32 mpg and a tank of 28 mpg. So as usual – folks not accustomed to driving hybrid vehicles will take a heavy penalty, so I’d plan on 15-20% less than the EPA combined number.

Interior build quality is excellent. Everything is well-assembled and there are no rattles. I have zero complaints.

Exterior build quality is a B-, especially for $60K. One of the rear bumper tabs was not fully pushed in (bumper popped out slightly during the drive home); luckily I was able to push it back in and it has held. Also, the paint has more dirt nibs than I would expect for a Lexus. This car came out of the Cambridge, Ontario plant.

Overall, I think it is a great vehicle for someone who wants a more polished Toyota product and is willing to pay a premium for the “Lexus experience.”

Thanks for that report and for your opinion. Over the past few years, I've been disappointed with the direction taken by, and the quality of, the Lexus models I've experienced. Friends have had a couple, I had an ES350 for a week or so, and drove a slightly used 350h from Concord Lexus. I'm seeing them now more as glorified Toyotas rather than the special, high quality brand they were 15 or so years ago.
 
I'm so torn visually on the "beak" above the emblem on the front. It's weird to me how it protrudes out. Otherwise i think they are a nice looking vehicle.
 
I think they are riding a perfect line. A very nice vehicle with the latest tech while holding on to more mature technologies where necessary to maintain reliability. its the perfect balance for those that can afford it.
 
If I had to replace my 2019 RX 350, I'm pretty sure it wouldn't be with another RX 350, especially when the RAV4, Highlander, Crown Signia, and outgoing Venza are so good. There's nothing wrong with the current RX 350, I'm just not seeing a significant enough difference between Lexus and Toyota to justify the price difference. Even the dealership experience doesn't matter since I bring the RX 350 to the same Toyota dealership I bring my Tundra to because they happily do it for less.

Arguably, the new Crown Signia may be the closest Toyota equivalent to the RX350h. When similarly equipped, the Crown Signia is about 8K or ~15% cheaper.

With the RX, one can get >8% off MSRP in most competitive markets. RX’s have traditionally sold for well under sticker and Toyotas aren’t typically discounted that much.

That’s all you got after a poor comparison !
Notice we own a Lexus too - that’s the big grill for no reason …
It was just a joke. Our Sienna has a massive grill.

Seriously though. It’s a hybrid which has an additional cooling system for the batteries. And the A25A engine was designed for up 40% thermal efficiency. I would imagine airflow is a big part of the above considerations.
 
On this newer model, is it smaller when compared to let say a 2018. I drove one and it seem a lot bigger that my friends 1999 RX 300.

I like the dimensions of RX 300.

Yeah, the fish looks more like our Lexus -
But, the radiator and air box intake runs from headlight to headlight on the Tahoe …140°-150° F transmission temps at 75 mph …
Both the 2017 & 2022 have tow pkgs …
 
I just test drove a 2015 450h last week, and cancelled my Carmax reservation to drive a 2016 (next body style) 450h today. I concur with all of these posts.

We own a 2024 RAV4 hybrid. We love it enough that I was considering a hybrid with trading in my ford. The Lexus hybrids price lower used than the highlander and rav4. Having owned a 2014 GS, I really really appreciated their finer touches inside. I wanted the RX to work!

The RX is a curious vehicle. I loved the 4400 lb bank-vault that the 2015 was. It was massive, yet felt small inside compared to the RAV. The windows lean in, my head was in the ceiling, and a 5’ 10” male would bang his head in the back seat. And it had no more trunk space than the GS sedan, iirc, after getting the numbers.

I hadn’t had a chance to get up close and personal with the newer body style until today. It’s very curious. The seats are far outboard, for a sizable center console but your head is awfully close to the window. The windows are small due to a high belt line, so I guess the closeness helps to not pinch off the view. The seats sit low, and you’re kind of in a hole. In the RAV, the doorsill dips down and the square sides keep the top of the door further from your head.

Now, the RAV doesn’t have the material quality, richness of features, sound deadening of the RX. As the tires wear in, even my wife has noticed it’s getting a little noisier inside. In addition, put a heavy guy in the RAV and it handles like it has a flat tire - the heavy load dynamics are actually a little scary in it. The newer RX-hybrid is 4800 lbs, the same as my f150, and I’d imagine it can handle the weight better, if he can fit it. But I also kind of get it, the interior of the RX is dimensioned a lot like a car, which is what it claims to be, a car-like experience - so maybe that is precisely why they set it up this way.

I’m too big for it, bottom line. I think Lexus builds good vehicles - I have owned one and known 2 - and would certainly be pleased to own another. 30mpg in a 4800 lb SUV ain’t no joke.
 
Nice vehicle, my only concern would be the four cylinder and the CVT which is not a great combo for NVH, but that’s the trade off for good MPG.
On the other hand, if they used a small displacement V6, I’m pretty sure the MPG would’ve been very similar and the vehicle would’ve felt much more upscale. But that’s sadly not happening anytime soon, if ever.


Good to see you dumped the original fill early. How did that look?
