2010 Lexus RX 450h Rated at 32/28 MPG City/Highway

2010RX450h The Lexus RX is the brand’s best-selling and, in hybrid trim, most fuel-efficient model, and with a new hybrid RX debuting, those fuel-economy scores are set to increase.

The new RX 450h is rated at 32 mpg in the city and 28 mpg on the highway for a 30 mpg combined rating with front-wheel drive. Opting for all-wheel drive costs 2 mpg in city driving, but the highway number doesn't change (30/28).

The RX 450h’s hybrid system offers a 20% improvement in fuel efficiency over the outgoing RX 400h, which was rated at 27/24 mpg city/highway with front-wheel drive. In addition, Lexus says the hybrid system has better acceleration and cold-weather operability, plus reduced vibrations and noise. The RX 450h's 295-hp powertrain is more powerful than both the RX 400h's and the non-hybrid powertrain found in the RX 350.

Looking at the bigger picture, the RX 450h has the second-best fuel-economy rating of any SUV, after the Ford Escape Hybrid and its Mercury Mariner and Mazda Tribute hybrid siblings, which are smaller, less powerful SUVs. Even the fuel economy on the all-wheel-drive model beats all other crossovers.

The Lexus also bests its stable mate, the Toyota Highlander Hybrid. The Lexus RX 450h goes on sale later this spring. Pricing has not yet been announced.

This is a phenomenal performance for such a large vehicle. There will be some reverse engineering going on soon in Detroit, particularly Dearborn. Toyota's Hybrid system rules.

This is a truly phenomenal performance for such a large and heavy vehicle. There's going to be some reverse engineering going in Detroit, particularly Dearborn.

O'Doyle rules too, buddy

hybrit,
get off the gas. you are becoming one of the annoying people on here. It's like you are intentionally trying to start fights in here.

This is a very nice vehicle. I am actually considering a used example of the previous gen.


Broq

H

Becoming one of the annoying people on here? Say one remotely positive thing about diesel powered passenger vehicles or one negative thing about the Prius and watch out! His story is typically repetitive, narrow-minded, and antagonist.

Original sheth

H is right on target. Hybrit is only about efficiency generated by Toyota products. If I'm not mistaken the Escape FWD gets 34mpg. The RX is impressive but so is the asking price. If you are really into efficiency there are cheaper ways to save gas. Much cheaper ways. Also, lets see if this model can live up to its EPA figures. Edmunds had a long term RX400h that was unable to match the lofty EPA numbers. They averaged low 20s.

Belly

I love how Stupid Shet is actually trying to call others on this site annoying ones. Please. You make up other names just you post more crap, yeah H.

And you are questioning this Lexus meeting its EPA numbers? The last time everyone did the same thing with the Cobalt and the Equinox, you just about screamed bloody murder. Way to use other people's arguments.

I don't know that I would call this phenomenal performance, but it is good to see Toyota adding the hybrid technology to other vehicles in its lineup.

Original sheth

Belly:

Not only are you hostile and immature, you are wrong. Someone said the Cobalt XFE averaged 25mpg based on ONE test. No other tests matched that performance and C&D recorded 29mgg. Most tests were close to 30mpg, not 25mpg that IL reported.

Also, the RX hybrid is not an addition. This is the second generation. IL had a long term first gen model and found the mileage disappointing.


I want to know why the RX gets 4mpg better city mileage than the Highlander hybrid which is essentially the same vehicle.

Daniel Lee

I enjoy Hybrit's comments. Hybrit keep telling it like it is and ignore these people who fight free speech.

Belly

Stupid Shet, I respond to what is there, nothing more. Quit crying because you are just proven wrong at every turn.

What am I wrong about? Uh-oh they had a hybrid RX before, you have now made a point. Good for you.

broq

Actually, Belly, I am the one who called Hybrit annoying, not Shet. As a designer, still in school to become an engineer, I find it offensive for someone to insinuate and say over and over that Americans, like me, are incapable of designing something on their own. You can
(and should)give whomever the props that they deserve without taking a shot at someone else. That's annoying and stupid.

Broq

DRRT

Belly,

I agree that Sheth made a mistake mentioning about the real world mileage. For comparison purpose, we should stick with EPA numbers. Also, to make this blog a nice community to share opinions, I would appreciate if you could stop calling him with that name.

Broq,

You always provide good and fair comments. I enjoy reading them.

Belly

Broq, I have never insinuated that American engineers or American workers cannot perform to levels that match or exceed other country's. Nor did I say anything like American's are incapable of designing something on their own. Quite to the contrary I think our country's workers can exceed any benchmarks. I just think when comes to Car companies like GM and Chrysler, and Ford up until a little while ago, they do not allow their workers to perform to their full potential because they are looking to save money to pad the corporate accounts. I also think in many instances the problems of today were forged in yesterday's "Old Boy's Club" boardrooms. I think that by only perpetuating some myth that domestics have consistently out done foreign makes is to ignore that history and to leave it intact. By demanding better products those companies will succeed, hopefully sooner than later. I think one of the best illustrations is the new Malibu and Fusion. GM, Ford, even Chrysler can meet the levels of quality, refinement, etc. of any other automaker but only if you demand it.

Now as for insulting Shet, I will respond to him as he responds to me or anyone else. So if you don't like what I write then don't you do the same. Broq, I am not going to go and find examples, but I have seen it where you have been not so nice yourself. So either practice it at all times, or don't preach it.

broq

belly,
I was talking about Hybrit, not you, in my comment about American ingenuity .

As far as me not being nice- Very seldom do I post anything negative on here, but there is a time for all things. If a car warrants a negative comment- no matter who makes it, I will post appropriately. Usually, I will keep my comments to myself though.

Broq

Original sheth

When comparing vehicles it only makes sense to compare EPA figures. The EPA figures are impressive. My point was lets see if testing shows the new model to duplicate those ratings. Not meeting EPA estimates seems to be more common with hybrids than gas only vehicles. The Fusion Hybrid and the GM truck hybrids have been known to fall somewhat short of their EPA ratings as well.

Tony

In the winter all Hybrids suddenly fall short of the EPA ratings. May be they should rate then by season/region?

Hybrit

Broq raises the banner of American engineering and preaches to everyone about it while driving a car (Ford 500) built on a platform entirely designed by Swedish engineers at Volvo. That's truly annoying. H apparently loves diesels, even though the cramped VW TDI gets 10 percent worse mileage in town than the cleaner burning, full size RX hybrid (Sorry clean diesel is not as clean as a hybrid). I praise the true hybrid innovators, not those who license the work of others, or the apologists who try to revise the facts to falsely support them.

H

Sorry Hybrit (and Belly for that matter) but your responses show you could really care less about the actual discussion of automobiles and are simply more interested in being argumentative and arrogantly boastful for no particular or logical reason other than to try and incite others to refute what you say. This is what irks people and is why you get such a negative reaction from people. Nobody is saying how crappy this RX is and no one is saying how Toyota is not innovative. Not everything is a pissing contest so don't treat it like it is.

Hybrit

Then don't read my posts, and don't keep your offensive comments to yourself.

Broq

You know what, Hybrit, I started to type out a long rebuttal for you, but then I realized that you are not worth it.

Broq

Belly

H, Vik, Stupid Shet, whatever you want to call yourself, I love how you are the pot calling the kettle black. Nice post:

O'Doyle rules too, buddy

and

Not everything is a pissing contest so don't treat it like it is.

You are an idiot. How many times you have turned each post into just that. If you want to improve the reputation of this blog DRRT, tell Stupid Shet not to post on here anymore. That would be a leap in the right direction.

Broq, usually I like your comments, but this holier than though thing is what you would call annoying. I posted what I did because I don't identify H as a different person than Shet. Sarcasm is hard to identify on a blog, I get that, but it is readily apparent what was said.

So as for the RX, I say the more vehicles with a hybrid drivetrain the better. As for meeting EPA numbers, from what I have seen domestic makes falter in this area more often that Honda or Toyota, hybrid or not.

vince

I think we should stop this "you vs. me" concept and praise any progress in technology and engineering. Competition is good cause it causes innovation, but we should not let it cause conflict. I applaud the RX for its progress and also clean diesel for making diesel better, etc. The question now is how can we make these EVEN BETTER. Common lets stay mature.

C

Sheth,
I cannot believe you would actuclly bring up the Escpae Hybrid to compare with the RX450h.

First of all, the Escape Hybrid is a compact SUV, the RX on the other hand is a mid-size SUV.
Doing this comparison is just like saying the Cobalt XFE is more efficient than a Fusion. Like apples to oranges.

Escape Hybrid: 34/31
RX450h: 32/28
Escape Hybrid AWD: 29/27
RX450h AWD: 30/28

So the Escape didn't have the RX completely beaten because the AWD version actually gets worse mileage dispite being smaller and way less powerful.

Original sheth

C,

I was merely talking about the most efficient SUVs on the market. Forget about size, the two vehicles are drastically different in price. The RX is also a V6 so it will be faster than the Escape. It gives you space (but same 5 seat capacity) and hp for about $10-15K more. The mileage is impressive for an SUV, and it should be for the price.

C

That's exactly what I am saying. Why are you bringing in the Escape into the discussion? It is appples to oranges.

You could say that the Saturn Sky had the Porsche Boxster beaten in price, and fuel efficiency. But it does not change the fact that they are not in the same class.

Original sheth

"This is a truly phenomenal performance for such a large and heavy vehicle. There's going to be some reverse engineering going in Detroit, particularly Dearborn."

C,

My comment was in response to that comment. The Escape is an SUV and it is very efficient. That is why I mentioned it.
