Hey,

I just went to the hyundai website, and I noticed that the mpg, hp, and torque went up in the new sonatas. Did they change anything in the engine to do this, or did they just tune it on the computer for better performance? Just wondering what has changed in the engine since I bought my 06. My car has been very reliable with just a few problems here and there. The only real complaint I have with its age is the massive increase on windnoise my car has.

Well, thanks all!

I don't have any info other than what you've seen on the website. However, I'm curious as to how the age of your car has any effect on wind noise. Are body panels coming off you car or something? Btw, Robotech rules.

d
Don't ask me how but it DOES increase with age. Just took my Car over 125 mph last month,

and it was impressive & scary. About the 249 HP Engine, we have no reports on any percived

increased performance over the previous Models, and the 06/07's does not have a Speed Governer,

which was put on 08 & 09 models.

I do like how I don't have a limiter (IMG:style_emoticons/default/smile.gif)

They had to have tweaked something, and perhaps it is an easy tweak?

btw- yes Robotech is the ****.

Well based on reading reviews and researching, I found that there is not much performance difference between the two V6 models primarily because weight has increased on the new models. But keep in mind that the new 09+ I4 Sonata does offer better performance then the older 06-08 because you get slightly more power and also a 5 Speed Automatic compared to the 4 Speed.

2006-2008 Sonata
3.3 V6, 235 HP/ 226 lb/ft torque
2.4 I4, 162 HP/ 164 lb/ft torque

2009+ Sonata
3.3 V6, 249 HP/ 229 lb/ft torque
2.4 I4, 175 HP/ 168 lb/ft torque

As for the limiter, I believe that the newer ones also do not have a limiter because over here in Saudi Arabia I have seen V6 models reach 240 km/h as well which leads me to believe that Hyundai has not put any limiter. But I maybe wrong as well because recently I was in an Azera 3.8 on a completely empty road and it also stopped going after 240 km/h at approx 4500 rpm. So its possible that they might have a limiter cap at 240 km/h (150 mph).
One other thing to notice is that car and driver tested both an 09 and an 06 Sonata. The 06 Sonata they say topped out at 144 mph, and the 09 Sonata at 147 mph; they believe both were drag limited...

Wow good info Hugo, but we do know V 33 did 152, even though someone said that was fake. Also keep in mind,

what goes for HMA produced Cars might not go for the other plants as well

“Although the displacement of the 4- and 6-cylinder engines remains unchanged, a new intake design for both units and improved variable valve-timing on the smaller one boost horsepower (inline-4 goes from 162 bhp to 175; the V-6 from 234 to 249), bump up the torque a touch and improve mileage to 22 mpg city/32 highway for the four and 19/28 in the V-6. “

“Two engines are available for the Sonata. Fuel-conscious customers will gravitate toward the updated 2.4-liter four-cylinder owing to its impressive 22 mpg in the city cycle and 32 mpg on the highway. Its 2009 revisions add 13 horsepower and 4 pound-feet of torque. The four-cylinder is unobtrusive as it goes about its tasks, and the additional power is as welcome as the improved fuel economy. A five-speed manual is standard, and a five-speed automatic is optional. Buyers wanting more power will likely find the V-6 to their liking. For 2009, the 3.3-liter V-6 gets 15 more horsepower for a total of 249. The V-6 feels strong and gives the Sonata near-sports-car acceleration; it covers 0 to 60 in 6.9 seconds. Fuel economy for the V-6 comes in at 19 mpg in the city and 29 mpg on the highway. A five-speed automatic is standard on the V-6 model.”

The exterior tuneup is minimal; headlights, grille, fascias, wheels, colors, bing-bang-boom. It's inside that voluminous cabin where you'll see a whole new world. The instrument panel, door trim, seats, lighting, center stack, audio systems, HVAC controls, and interior colors are all redone. The look and feel of these components are so much better and more harmonious. Switchgear is more logically located that you can, for the first time, get a nav system. At $1250, it's priced right, but unfortunately only available on the topline Limited.
There's more power underhood. The four-cylinder version goes from 162 horsepower to 175 (green states get a PZEV rated I-4 still good for 168). That'll play just fine with Camry (158), Accord (177), and Malibu (164). Variable valve timing now on both intake and exhaust sides of the combustion process likely accounts for the bump. Yet EPA improves from 21/30 to 22/32 (with automatic trans). Four-bangers make up about 70 percent of Sonata sales volumes, and given ever increasing fuel price levels, that equation may tip further. A five-speed manual transmission is still offered, while the automatic goes from four to five ratios.
The Sonata's V-6 gets more power, too, but at 3.3 liters, is still displacement-challenged against the category. Most players pack 3.5-3.6 liters of engine, good for 250-270 horses. At 249, the Hyundai can come to the party, but not lead it. But this engine loves to rev, and EPA also improves, if only by a hair, from 19/28 to 19/29.
The underpinnings are retuned for better ride and improved handling, the latter especially in the SE model. Hyundai has also put effort into quelling noise levels, an issue, as noted, with the previous car. As before, there are six standard airbags, four-wheel disc brakes with ABS, and -- this is a big one -- standard electronic stability and traction control. Camry and Altima charge you extra for these safety systems.

Nice! Thanks. I wonder how much that intake is..

Hugo, can an Azera really hit 150 mph.... I'm skeptical.

The new intake design doesn't have a resonator box on the driver side like the 06-08 does... it attaches to the ram air and that's it. There is also another filter besides the replaceable filter that cannot be moved. It sits on top of the replaceable filter on the clean side. I don't know if the 06-08 has it or not. I want to rip that one out since it seems to be restricting air flow...

Sounds interesting....Does anyone have a picture of the 09' engine they can post here?

Thanks Miami (IMG:style_emoticons/default/smile.gif) , I think that 152 mph is possible because V33 did have install an exhaust and intake to his. Maybe HMA manufacturing doesn't place limiters on certain vehicles.

I will try again on an open road again and see how it goes, it takes a long time for it to get from 230-240 km/h for some reason and even when your on either 5th gear or 4th. But after it hits the limiter at 4th and goes to 5th it just stops completely and you just see it cruising at 240 km/h (150 mph)

Yes my friend, they sure can (IMG:style_emoticons/default/smile.gif)
Azera is a very popular car over here especially the 3.3 V6 model and even that goes to 240 km/h (150 mph). I took the 3.8 Azera and still found out that it maxed out at 240 km/h. Here are some videos from friends in Saudi Arabia with Azera's going fast and some hitting top speed....
****Notice how 3.3 Azera and 3.8 Azera both have the same top speed which is 240 km/h (150 mph)

This came from a Video on YouTube that V33 had made, I froze the Video and made that still you see.

Please don't try this Hugo as it can't be safe to do 150 +

My 09 Limited V6 does not have a speed governer. I recently took my car to a track and was able to get it up to 143mph (IMG:style_emoticons/default/smile.gif)
