hybrids needing premium gas vs regular gas for the non-hybrid and that there are less hybrids in dealer inventory so you can't get as good a deal on one made me pick a non-hybrid rx. dealerships in my area said they maybe got a max of 5-10 hybrids in inventory and they all went out the door quickly so they said they couldn't give me any deals on them vs like 100-150 non-hybrids in inventory

Another thought. I am not against hybrids since I purchased a 2005 prius and it is still running at 155,000 miles after the 1st battery was replaced at 102,000 miles. It has paid off. You also need to factor in the depreciation rates of hybrids and EV's. It's currently running at 60-70% after 5years vs gas at 50%. I assume when one purchases the hybrid or EV, it will be a long term purchase. With technology on batteries changing more rapidly, current purchases now will render more depreciation in the future and also purchasers of used hybrids and EV's do not get any credits that the original purchaser may have gotten. That is the reason I will not purchase but rather lease.

When we were looking for our CPO there was probably 2-3 (If that) Hybrid CPO per dealership within a 100 miles radius. The prices they were asking for them were are rather crazy. You also don't get the options that you would normally get buying a CPO for that price point.

Unlike Tesla batteries which will cost about $35,000.00 to replace, it has a better warranty and 80% guaranteed effectiveness after 100,000.00 miles.
Batteries as a whole have limited full recharge cycles and capacity diminishes after each full recharge. Granted technology is advancing on batteries I would only lease any hybrids or EV in the future to replace the cars every 3 years so I have a fresh battery without worry.
Our ES 300h have always used 87. I have used 87 octane in our 2015 RX450h and currently 2017 which both premium is required. Experimenting with the other two levels, I have noticed zero difference in gas mileage or performance. I have used 87 in cars that have required premium for over a million miles and have not had one problem.
I always revert back to two MIT graduates that are car mechanics who had a syndicated radio show called Car Talk for 35 years.

From the USA Today:
The only modern engines that should really need premium are those with superchargers, which force-feed fuel into the cylinders. "You're driving along and just tramp the gas and the knock sensor cannot sense the knock fast enough in some cases," because the supercharger boosts pressure so fast, says Bob Furey, chemist and fuels specialist at General Motors.

Burning regular when the owner's manual specifies premium won't void the warranty, nor damage the engine, even the most finicky automakers say. "You're giving up perhaps just a little bit of performance that a customer wouldn't really even notice, it's so slight," says Furey.

I bought last year used a one year old ES 300h and a RX450. On the Lexus lot the ES300h was the same price as the ES350's and the RX 450h was $1,500 more dollars than the RX350's. This made it a true no brainer.

Keep in mind some regions have plentiful hybrids while others get very few and can deny discounts on them. If you live in a region that doesn't sell them for the OEM $1000-$1500 more than gas you should consider going to buy in another region or avoiding them.

It may not void the warranty, but if extended for a long time it WILL damage the engine. The computer can retard the ignition only for so long and what if it malfunctions.

How is the stop start system on these things? I can't imagine the system is smooth after a while after the wear and tear on constantly starting and stopping the engine.

Stop/Start is marketing crap - the small amount of fuel savings will be more then offset by wear on other costly components. You may save a few cents now and pay a lot of dollars later. In Australia we don't have Stop/Start on the RX (NX has it)

It does not have a starter motor with grinding teeth. It is started via one of the MGs and is and always will be smooooooth, and will only start the ICE when needed.

Well my friend 2019 MB GLE is very smooth with stop/start, but 2 BMW I've driven X3 & Clunman, were NOT so it may depend on the manufacturer.

I hope they just mean on the hybrid (and maybe you did too and I'm the one out of the loop)... but the standard RX in the USA does not have start/stop either... and I agree... I detest it.

So why is the manufacturer recommending premium fuel for the hybrid? I assume then if not for the performance then is it for the mileage? Did you notice a difference with mileage with the regular fuel vs premium fuel? And if this was so, why wouldn't recommend premium fuel for the gas version to increase mileage? It seems likely the reason is that even though the engine will automatically retard the timing if regular fuel is used, they do not recommend it because it was not design for this purpose but to prevent engine damage if regular is used. There must be a reason why they recommend the premium fuel because there is no advantage for them otherwise.

Don't know why you would only lease, when the battery is guaranteed for 8 years and 100,000 miles.[/QUOTE]


As you get closer to the end of warranty, resale value will diminish quite a lot even if you replace with new battery, the warranty will be nowhere close to 8yrs, 100,000.
Also new models will have increase driving range and mileage as technology advances.

Supply and demand sets the resale price. Many more gas then hybrids due to the fact gas outsells hybrids by quite a bit. Dealers know this and make quite a profit on the short supply and can command higher prices. Market is not quite ready to go completely for hybrids due to EV's coming aboard. So consumers are now contemplating on EV's vs hybrids. Also tax credits are still available for new EV's coming to market.
