CREATIVE FOAM : What the Media is Saying About the New Acura TLX

The 2015 Acura TLX is receiving rave reviews for NVH (noise, vibration and harshness) performance . Creative Foam is the proud supplier of foam panel barriers, foam door plugs, foam fender enclosures, and compression molded nonwoven stuffers for the new TLX.

Edmunds’ Review

http://www.edmunds.com/acura/tlx/2015/road-test.html
“Lots of noise-cancelling measures have been put in place in the new TLX, including a significantly more sealed body and the use of acoustic spray foam in 10 different spots. They must work, as the cabin remained nice and hushed, making for easy conversation. Wind noise was never an issue, and the engines are nearly imperceptible at highway speeds. They don’t cause a ruckus at full throttle, either.”


Automobile Magazine’s Review:

2015 Acura TLX Review

“The rest of the time, active sound deadening and liberal amounts of conventional insulation make this one of the quietest Acuras we’ve driven.”


Motortrend’s Review

2015 Acura TLX First Drive - Motor Trend

“Meandering through 300 miles of West Virginian back roads (I still have John Denver music stuck in my head days later) also showed the TLX to have a new level of refinement. Less noise makes its way into the cabin, thanks to …noise-blocking panels inside the doors, and beefier door seals.Torsional rigidity is up significantly over the TL, and the TLX drives like it – the chassis feels taut and solid, while ride comfort remains strong even if the spring/damper combo is tuned on the slightly firm side of things. One caveat: That extra rigidity means extra bracing, some of which eats into pass-through space on the 60/40 split rear folding seat.”


Slash Gear’s Review

http://www.slashgear.com/2015-acura-...edan-04339624/“More importantly, the body has been sealed for better sound insulation, with Acura quoting 50-percent less body leakage thanks to…, triple door seals, and acoustic barrier panels installed. Acura’s engineers even opted to fill in the little holes left over by the manufacturing process in the name of keeping the noise down. You may not see all these efforts, but they’re what help elevate the TLX over a mainstream Accord.No matter the trim level, what’s most noticeable is the sound – or, rather, the lack of it. Acura’s noise deadening processes may be extreme, but they pay dividends, and what you actually hear in the cabin is an order of magnitude less than the noise actually going on outside.”

It's pretty quiet. Im used to Honda products' incessant tire noise. This, and my RLX before it, are the best I've ever had in the noise department. I've been driving Hondas for almost 30 years, so I can hear (LOL) the progression.

Lots of good talk about tires & brakes on the other thread. One thing to note on the how quiet is it. Summer tires are naturally nosier than the TLX OEM tires. So anyone thinking about a switch should remember that if road noise reduction is important to you.

Personal rule of thumb, In cars everything is a trade-off.

The 2018 v6 Tech loaner we had a few weeks ago was super quiet with no wind noise around the doors. It sounded like there was additional sound dampening material similar to what I had installed on another car. It just sounded like it was well insulated. Well, the A-Spec we just got is quieter than our 2015 TLX V6 Tech but we can hear wind noise with less of an insulated effect.

Is there a difference in sound dampening/insulation material between trim levels? What gives?

Wind noise from sharkfin antenna

Hi all --

I'm new to the forum and thought I would respond on this thread hoping one of you have experienced this noise I'm having. I've only had this happen a few times but it is very annoying. The situation is a stiff cross wind (<15mph) at highway speeds. The sharkfin antenna on the roof is making a "tuning fork" kind of noise/vibration that reverberates throughout the cabin. It continues as long as the crosswind hits it. I listening to that noise for 3 hours straight this past weekend and it about drove me crazy.

I called the dealer and they (of course) said there wasn't much they could do about it -- it has to do with the shape of the antenna.

Any ideas how I could mitigate this?

Hum - are you sure it's the sharkfin antenna? Never experienced this type of issue. It could be missing underbody rubber plugs that the dealer is supposed to install at time of PDI (the plugs are there to prevent wind noise, actually). THey are fitted into holes on the undercarriage of the car that are used to tie down the car during shipping. Check the TSB section for the "TQI" info.

3 TLXs and all have been smooth and quiet on the highway. Conversations are normal, music volume is normal and doesn't require much adjustment. I also undercoat my cars, some for the rust prevention, but more so for the road noise reduction.

I lease and seldom go the full 4 years, and I also know the dealer uses a good quality product.

How well does the RLX do compared to the TLX in NVH?

The new Lexus ES achieved 67db @70mph in testing.

On the summer tires a big test was just run by a 3rd party & this is the top 3 in running quite.

In Tyre Reviews' test, the Continental made the least noise at 50 mph, followed closely by the budget Accelera tire. The Michelin came in third, while the Goodyear finished dead last.

Having leased both a RLX Sport Hybrid and my current TLX, I can tell you that even though both are quite good in the NVH department, better than other Honda products, the RLX is head and shoulders above the TLX, as you would expect of a flagship sedan. I don't have numbers to back me up, but the difference is immediately obvious on driving both. The RLX PAWS, however, has lots of suspension clunking, at least in the 2014s and 2015s, so not as good. You can now find RLX Sport Hybrids starting in the mid-20's used...it is currently the ultimate bang for the buck used luxury sedan. I recommend without reservation.

But sadly the RLX would get demolished by a Hyundai equus, Genesis, Kia k900, and LS 460 in that price range.

I can't get over why they used fake wood? A camry would use fake wood, not a flagship!

I have been torn what to buy for some time.

Problem is, I want a car built in Japan! My only option is go LS 460 or Acura RLX advanced package. I would like to keep the car for 10+ years at least.

My current 23k Toyota achieves 67db on fresh tarmac and I usually average 70-73, with spikes to the 80's on terrible stuff. Thanks to sound deadening! No acoustic glass or 3rd door seals either.

So I just did a quick search of CarGurus after seeing your post. Holy smokes, you can get a 2015-16 Equus for UNDER $20k. Kia K900 is low $20's. Great time to buy a used luxury car for sure.

The Korean luxury cars all can be had in the 20k range with sub 30k miles. Same goes for the LS460, that's why I'm having be a hard time justify going RLX.

The only thing the RLX wins at is no turbo V6 TT or V8 and simpler 6 speed transmission. That rear wheel steering doesn't seem reliable and I don't want the added wear from all wheel drive.

I am looking at 2017 RLX advanced package at a Toyota dealership with 10k miles and they want $34,599! That's robbery! I couldn't justify buying it at over 25k imo

I’d buy a RLX Sport Hybrid, not a PAWS RLX. You should go to the RLX section of Acurazine and ask the regulars about what they think.

I could care less about hybrid batteries and don't want to be stuck with failed generator like a Prius and have to spend more than the cars worth in 10 years.
