I am thinking of replacing my 2015 RX450h with a 350h mainly because I want car play and dynamic back-up lines. It's the bells and whistles that get you! My 450h is in perfect shape. It replaced my 2005 400h (first year of Lexus hybrids) which my daughter now has. The 400h has 190K miles on it and has never had anything go wrong with it. How could I not buy another Lexus hybrid? A couple of questions:

Will the 350h handle better than my 450h? Will the 350h have noticeably worse acceleration?

Any other comments are welcome.

 

I have a 2016 RX 350 gas F sport and a 2024 RX350h. The 350h handles much better and is much smoother and quieter for me.

When it comes to acceleration, the V6 is definitely faster. 350h has no problems merging and getting out its way, but the 2GR V6 is faster.

On the other hand the 350h uses half the gas for the exact same trips. I personally love the 350h.

 

According to online resources, the 2015 RX450h does 0-60 in around 7.5 seconds and the 1/4 mile around 16.1 seconds. The 5th gen RX350h does it in around 7.4 and 15.7 seconds, so they are roughly the same.

The 2016 RX350 did 0-60 in around 7 seconds with around a 15.3 1/4 mile.

 

It will feel slower due to two fewer cylinders but on paper they are pretty much the same in terms of acceleration.

 

The 2010-2015 Rx450h actually does 0-60 in 6.9s. faster than 4th and 5th Gen.

Handling is poor compared to both.

 

Parts of me miss our 2010 450h.

 

Which part?

 

Better use of interior space, quieter vehicle when pushed on an aggressive acceleration, adjustable back seats (not on base 350h), quieter vehicle overall, better use of interior space, This all personal preference.
