Does anyone know the max speed of RDX?

Thanks..

BleuM&M

In another thread I mentioned nudging 170 mph and 737Jock pointed out that due to the tires I was running, it was actually 162.8.

scottRDX

Holy crap! 162 mph? That is amazing! Is the RDX stable at that speed? It seems to me that Acura is being very conservative with the 240 hp figure. Maybe they don't want to tread too close to the MDX's 300 hp.

LuvMyRDX

Wow!

wrestrepo

I don't buy those numbers....not on a regular road anyways...are we seriously thinking 170 mph is possible? (or 160 for that matter)

sj993

Well given that the speedometer is listed at 160 MPH as it's max I highly doubt the RDX will go that fast. I would say more like 120-130.

I did a google search and found this link which states the top speed is 130MPH (governed).

Be careful not to assume a car's top speed by the speedo. I had an '87 Mustang LX 5.0 with a speedo that only went up to 85mph (why I do not know). I know for a fact, racing a buddy of mine with a GT, the car was capable of 130+. The GT option is what got you the 140mph speedo in that car. The speedo may be a true indicator of top speed in some cases, but it certainly isn't for everything out there.

LuvMyRDX

Can't really say this dude hit 135 since the camera went off the speedo, but he did hit at least 130. Dunno if it's "stock" either. Love the music in the background. haha

wrestrepo

There is a HUGE difference between 130 and 160....as a matter of fact, videos on youtube show how difficult is for the RDX to go over 100 mph...sorry dude, not buying it..

BleuM&M

The RDX pulls like a train past 100. Been there, yelled that. Very stable and gotta love the sound of a turbo V-Tech putting it down. I don't know the top end of my unit, but I would think it's in the 125-135 range, given the primary boat anchor at those speeds - aero drag.

I was April Foolin' when I made the post up there - I was actually talking about my Z-rated tires and how I would still be in the tire 'safety' zone at 170, and 737Jock reminded me that 170 on the speedo would be 162.8 because of the diameter of the rubber I'm running.

I agree with wrestrepo, there is a HUGE difference between 130 and 160. This is not a vehicle I'd want to be in at 160 - that speed is totally out of its design envelope.

LuvMyRDX, I had a '79 Capri turbo with that 85 mph speedo and Bonneville Salt Flats gearing. After playing with the distributor, adding water injection and some turbo abuse, I got that speedo to wrap around the dial nearly 2 times. In retrospect, talk about stupid fast!

737 Jock

According to Tire Rack, Bleu's Pilot Sport Zs are actually Y-speed rated to 186 mph, which in the RDX would likely require full throttle and a near vertical descent from say...the top of Everest.

A second (and just slightly more plausible) option would involve JATO bottles and a lot of room -- ANYTHING can be pushed to 186 mph with enough thrust. Throw in a jump ramp and about 27 tractor-trailers, and one may find oneself the reigning star of Jackass III -- a most excellent stunt for April 1st, by the way -- and in which case one may ponder if the speed rating was actually pronounced "why?"

Truth be told though, I settled for Bridgestones, and I'm just jealous of Bleu's Pilot $port$ and his seemingly Trump-like resources required to obtain them. Do we doubt there is Trump-esque arm candy in the right seat?

LuvMyRDX

haha...nice. Those late 70's early 80's Ford turbo'd 4's were damn good runners with some massaging; though they didn't last very long when you started putting that sort of power to 'em.

The farthest I could get my speedo to wrap back around in the mustang was straight down when it got stopped on the trip odo reset stick. About 105ish.

BleuM&M

Nice. Few things I've witnessed have been more alarming and shocking than to see a C-130 with JATOS get tossed WAY up into the air. I mean those suckers got near vertical, not to mention rotating after about 60 feet. Must be quite a rush for those cargo jocks to light them off. I think I'd try one on the beagle next door before my RDX. But a good suggestion!

My Trump-like re$ource$ are being buoyed by the price of premium and 3 inline Tornado fuel savers (thanks XLR8R) so now I am siphoning off the tank to sell to the neighbors.

I do have to say my sweetie is very easy on the eyes, doubly so considering she is a granny. I am blessed indeed! Good luck with those Bridgestones - I never had much luck with them.

o yea

go fat albert!!!

I got up to 115mph quite easily. It was amazingly stable. Felt like I was driving 90mph in most other vehicles. It still had a bit left to give but I was running out of highway and was quite satisfied with 115 anyway.

ThePlainsman

I've taken my RDX only to 100-105. Ran out of highway, like you. But I've taken my 2002 Altima V6 3.5 liter up to 126 and it was rock solid stable. I dusted a Bimmer 3 series.

jumbosizeme79

i highly doubt that, as others mentioned the speedo ends @ 160 and unless you took out the gov chip i dont think it allows you to go that fast..

BleuM&M

Shoot, I forgot to look at the speedo to see if it stopped at 160.

The chip thing reminds me of when my friend had a slightly massaged SVO Contour (back when those were fast). I told him I was going to get a chip for my 4-banger and beat his ride. He just looked at me and said, "You'd better get two."

BleuM&M

Oh, and look at post #10.

m900s

Top speed is 130 flat , 135 slight downhill

BleuM&M

Yep, mine went BOOM at 67,000 miles when I missed a shift to 3rd and over-revved. I had a friend at Ford who was a tester - as in TTD (test to destruction) and he always called my Turbo Capri a Turbo Debris. Other than a blown head gasket at 30,000 he was impressed it lasted as long as it did, especially since I beat that thing like a rented mule.

JGard

seriously, no WAY this car does 160mph. It's a brick in terms of aerodynamics, for one thing.

Otherwise, I'm sure there is a governer for 130mph.

Finally, all car speedos are ridiculously inaccurate. Even at an indicated 130mph in our car, I'm guessing actual speed is more like 120mph.

I recall an article years back about speedo inaccuracies...and the Porsche 911 was the worst, indicating 220mph when it was in fact going about 185mph. That's a huge difference.

Why cars with in-dash GPS don't use said GPS for the speedometer reading, I don't know. GPS is as accurate a speed measurement as you'll get, and that's the one thing I miss about my old TomTom.

The top speed on the RDX cant be much more than 130mph. Now we have to understand its governed electronically. So without the govener {(and his prostitutes) NYC joke} I would suspect 140-150 mph top speed...?

Tomcat999

I got to about 208 km/h on a long flat straight last fall.
(That equates to about 124 mph).
Still felt like there was more pull left- but backed off
the pedal. The RDX seemed very stable but I wasn't
exactly about to test the SHAWD abilities at that
velocity. And yes- wind resistance is definately
a factor here- but who really cares- since we never
are supposed to go there anyway?
Suffice to say- beautiful ride and LOTS of power
and agility.

Hmmm... I think I would have not dared to do that here in Vancouver, even for a few seconds, the cops will be on it in a blink of an eye... There is simply no realy place, like a straight empty highway to do that here... too congested roads.

I would feel better if I could do that in a deserted airstrip, devoid of all obstructions...

I have no doubt the turbo 4 iVTEC engine will get the RDX close to 200 km/h... The torque and HP numbers clearly make it possible.

Question is: Is this simply a "just curious" exercise for some folks, or "reason to brag" for others... For the former, I would suggest a dragstrip, deserted airstrip or backroad, because at that kind of speed, doing it on regular hwy or street, is simply insane. A slight miscalculation or slippery road or unexpected appearance of a car in front of you, it's sayonara, esta la vista baby... this kind of thrill can kill.

For the latter, "reason to brag"... unless that's how you drive everyday, at 210 km/h, which I doubt, those top speed numbers mean nothing... If you live in Germany, and travel on the autobahn is your daily route... that is definitely something you want to know about in your car...

LuvMyRDX

haha! To be honest I have to agree with your friend...to get 67k out of one of those things, even in stock trim, was a pretty amazing feat. I bet that sucker was fun while it lasted though!

Jesse Fulton

I know that the rdx is capable of doing at least 145 maybe 150. I got mine up to 137 at 5500 rpm on the way to california from Arizona. Since the red line is at 6800 i figured i could have pushed at least 145.

JGard

Just because the engine has room to go before redline doesn't mean it's going to get there!

your indicated 137 was likely just a hair under 130 and you probably couldn't have gone much faster than you were, because of the governor.

neo1738

beg to differ, RDX EASILY hits 100 and goes past. only done it couple times but every time it was easy...now i never topped 115 but honestly who needs to

bialkoni

Pretty much every car I have owned I have taken it to 100mph once(and only once) just to see if it would, I had the RDX to 108mph it still had a little more and was very stable. now back to driving 6mph over the speed limit.

MMike1981

difficult to hit 100mph? lol what RDX are you driving?

the RDX is PLENTY STABLE & planted at 100mph +, no problems here.

mav238

This is really interesting, everyone is so interested in the top speed of this car...

I can understand the "curiosity" factor... but man... going on a local road @ 200 km/h is a little insane...

Honestly, JMHO, I really don't care much about the top speed of the RDX, because, I will not be trying that stunt without facing the possibility getting a ticket or getting myself and/or other people hurt... People, both scenarios can happen... If you really have to taste for yourself how the RDX does at the top speed, at least do it in a track or deserted airstrip or backroad...
Sure it's fun and thrilling... not until you get hit by a hefty fine and/or car impoundment for seriously excessive speeds... or kill someone in that thrill...
A brand new 2007 BMW 335i, with 4 young people in it, here in greater Vancouver, were killed when they drove their bimmer to > 130 mph, on a straight road, they lost control and spun off (yes, a bimmer can spin out too), hit a tree squarely, broke the bimmer in half, complete wreck... Don't tell me they were in a hurry to get somewhere... they were simply seeking the thrill and also probably wanna see how fast their bimmer can really go... They were not racing with another car...

So why do people really care about the actual top speed in the RDX, when you are never really going to drive at that speed constantly anyway?

I enjoy the high torque aspect of the RDX more than it's ability to reach a particular high speed...
to me, being able to get to a certain speed, like 60-70 mph, in a very brief time, represents a practical performance trait that is more favourable than topspeed. Imagine you were in need to pass a couple of cars, to make an emergency lane change, would it not be great to have (and feel) that freight train like push in the back?

Tomcat999

mav238- I for one can certainly understand your very logical stance on this subject. Clearly it is foolish to think that one should simply speed around in this powerful vehicle and not expect some sort of consequence (hopefully not one like the bimmer you referenced to- and sadly the horrific results). I would say that in my case I had the opportunity- given my decades of experience and the favorable geography and forsight given the area (complete desolation) that it was possible to do safely with minimal danger, especially to others- to check out some top end abilities of this vehicle. I think one has to make the distinction between just bombing around trying to get a thrill and impressing some others to just checking out performance responsibly. Like you- I really don't care about the actual top speed of this vehicle. I revel in the torque and responsiveness and ability to reach reasonable velocity in a short period of time. That's the best part for me. At the time of my 208 km/h- it was purely a great opportunity and a very short lived event because like you- the mounties can jump in when least expected and the consequences can be regrettable! Let's hope any test pilots can exercise caution and common sense...

Mav....I used to live in Vancouver, I can understand your hesitation at driving at high speeds there. It's not like you're going to hit the Sea to Sky highway doing 200km/h. There is really no place to open the throttle anywhere near the city.

Now, I can't speak for everyone else here, but I currently live in Texas. Highways are flat, straight and, depending the location and the time of day, barren. There is very little danger to testing the limits of your car for a couple of miles.

And why do it? Why not? The thrill of going that fast (even if it's only one time ever). Curiosity to see how fast the car goes (you did pay money for a turbo after all). And yes, even bragging rights.

For myself...I'll try out the top speed a couple times when I have as controlled conditions as I can manage. It doesn't mean I drive that fast all the time and I don't put other people at risk.

mav238

Good for you that you know well enough to do the high speed trials in wide open roads...
But a question for you... Obviously, you do understand that in both the USA and Canada, if you are caught doing seriously excessive speeds, there is a super hefty fine associated with it, and in some states, potentially have your car impounded as well by the Law. Thrill aside, is that hefty fine worth it?

I was on I90 going from montana to Idaho a few years back in my Infiniti QX4, and there was this wide open road, I was doing about 90 mph (no daytime speed limits in Montana freeway). But when I drove into Washington State, I slowed down to 80 mph, and sure enough, even though the freeway was wide open, barely a car in sight for miles, there was "uncle Sam" hiding behind some large boulders, ready to catch some drivers, probably wanting to hit the "topspeed" given the wide open freeway...
So what do you say to the State Trooper, when he pulls you over... do you say "Awww... officer, it was a wide open road, and I was just raring to see how fast my car can really go, it's brand new you know, I promise I do it once and never again... just wanted to feel what 150 mph is like... I know you understand the thrill behind it right?"
Officer: "Sure, I totally understand, bud... I was young too... But by the way, I still have to uphold the law you know, you do understand where I am coming from right? So thank you, and here's the ticket for $600 for doing 75 mph over the speed limit. And please step out of the car, because we have to take a look at your Supercar and keep it for a period of time..."

Irregardless of whether you say it's a once in a lifetime thing, ultimately, going 150 mph on a freeway here, is doing excessive speed according to the Law.

I guess for a number of you, it's worth the risk of the hefty fine and potential impoundment of your car... But why not do it in a place away from any road or freeway, no cops, and safe to test it...? It makes perfect sense, don't you think?

lilfeat

I guess the answer R*D*X* is no, nobody here knows the top speed of the RDX.

I think it is odd the you never really/rarely see a complete review of Acura cars in the Auto Rags. I read C&D and Automobile, and they never have anything deeper than a comparison, or short take article.

I wonder if its because Acura does not grant that kind of access to their cars for longer testing/abuse.

mav238

One more point:

At > 200 km/h, things are flying by in a blink of an eye, your eyes are focused more on possible objects or cars in your way. But no matter how good your eyesight may be, you will not pick up a patch of slick oil in your path, because at that kind of speed, the surface of the road looks pretty much the same everywhere. Plus, the tires on the RDX are not the ultra-high performance type tires, the latter has the tread compound to deal with high speed traction. The Michelins all-seasons are great for touring, not high speeds.

When you hit that slick oil patch, AWD means nothing, especially when you are at > 200 km/h. The higher centre of gravity of the RDX, will lead to eventually, spun out of the car, and rolling over. Your car can be flung as much as several hundred feet along.

Here is an example of an incident when the RDx was speeding,,,

MMike1981

the example above.....how do/did u know that car was speeding? this came from another thread, wasnt that RDX hit, theres clearly side impact involved in that accident and an accord behind it with damage to its hood.

not really a neutral example of wreckless driving.

i dont think the point of anything in this thread is to drive the car with the pedal floored for a length of time. its ok to be curious, not ok to be an idiot. all this thread was looking for is what is the top speed lol

sl_33

Ahhh....so that's what the underside looks like.

In response to worries about getting caught by the cops....yeah it is a risk. However, if you are familiar enough with certain areas, you can be fairly certain that cops don't set traps there. If you're still worried about it, have a friend drive ahead a few miles and check things out.

And I'm not sure if they impound cars for excessive speeding in Texas. I've never even had a speeding ticket. Knock on wood.

And if I did get pulled over, that's is pretty much what I'd say. 'Look officer, new car...only got XXX miles on it and wanted to see how fast it would go on the open road.' There is pretty much nothing else you could say at that point. Just hope he understands and gives you a ticket so you can be on your way.

Oil slicks...sure. But now you're getting into some pretty big IF territory. IF a deer jumped in front of me. IF a guy pulled out in front of me. IF I suddenly got something in my eye. IF a ufo abducted me. Any of those could happen, whether you're driving 30mph or 120mph.
