For those that want to compare the GT500 with the 13 RS3... here are some resources

[RaySkillmanFord]

The fact is, there is no doubt both cars are fantastic, but everyone should understand the big picture. The RS3 with a 3:73 and a close to 300lb weight advantage is no slouch compared to the 662hp GT500. Hopefully these links will help you see real world results....

So many times these cars are misunderstood because people see a bigger horsepower rating and assume a car is faster, but weight and gearing have allot to do with it. The fact that they dropped the GT500 down to a 3:31 to hit a 200mph top speed and eliminate the gas tax and it weighs about 300lbs more, really narrows the gap between a Stage 3 up to probably the 150mph range. After that, The GT500 will probably beat it, but in the normal range of driving, I doubt it unless you put a set of 3:73 Ford Racing gears in the GT500 or something, which some people will do aftermarket. The big point is, Both cars are awesome, but there isn’t a huge gap in performance as marketing tactics would lead the lay person to believe.

Keep in mind, the 2010 Stage 3 made 509 RWHP on our Dyno. The 2013 made 515.

Do you have an hard evidence of this 300lbs different? Roush kept the RS3 weight figure so tight in the Pentagon that nobody knows for sure the exact curb weight but from what I've research with actually numbers listed at FORD

Stock GT base curb weight= 3618lbs
Stock V6=3501lbs (manual)
2013 GT 500= 3871lbs
Boss 302= 3632

So if my math is correct and the RS3 is "300lbs lighter" then 2013 GT 500 (3871lbs) ,the RS3 should be coming in at 3571 lbs? That's 70lbs lighter then a manual V6, 61lbs lighter then a natural aspirated Boss 302, how's that possible with Roush starting with a base gt curb weight of 3618lbs then adding on a blower, big brakes, cooler, aero kit, etc..? The last Stage 3 curb weight that was officially recorded in 2007 is 3920lbs by http://www.robbreportcollection.com/...3-Mustang-2007 and we all know the Mustang has gotten heavier not lighter. From all the Roush authorized dealers including Saybrook Ford, I've seen dealers are split when they list the curb weight of the RS3, most will just look at the door sticker or website listing for the curb weight and list that as the "official" RS3 curb weight, the problem is that the sticker on the door is the actual sticker from Ford Co listing the stock GT curb weight before the car is shipped to Roush for the RS3 conversion, its the same confusion when you look at the door sticker for the correct PSI for your wheels when Roush should have changed those numbers because the door sticker PSI is based on stock GT wheels. The other half of the dealers actually have the RS3 or Stage3 curb weight listed as "starting curb weight 3618lbs" some even has it starting at 3501bs as a reference to the V6. Now what is actually true is that the 2013 GT500 is 300lbs+ lighter then the Camaro LZ1, I think many people got that number confused with the RS3. Eventhought the 2013 GT500 has a gob of HP, due to its new rpm launch control, it still can put those horsepower down to the ground with a 0-60 time of 3.5 seconds and 1/4 of 11.6 @125.7 mph, all on street tires, I am curious to see what the RS3 can do with all its HP and without launch control.

I weighed my 2010 Stage 3 a couple weeks ago on a truck scale and it was 3680. My Trak Pak on the same scale last year was 3600.

Car and Driver has a 2010 427R 4.6liter at 3700lbs so its on par with what you got, Trak Pak got the smaller wheels so it should tip the scale a lighter, the base 2010 GT curb weight is 3400lbs + (edmunds) so your Stage 3 gained 200lbs+ over a stock GT, but the 2013 base GT gained some weight at 3618lbs, so both the 2013 RS3 and GT500 has some significant weight gain but I still don't believe in a huge weight difference between the two. A 2010 GT500 is 3917lbs, Ford really bloated the 2010 GT500 up, but they actually managed to drop 41lbs for the 2013 GT500.

[gtncpa]

My Vert was on the scales a couple of weeks ago at the track. It weighs 3650 with 1/4 tank of gas. No supercharger, but it has a roll bar and subframes. Oh, that weight was with the spare tire and jack out of the car. I think I read a vert weighs 150#'s more than a coupe.

My 02 Lincoln LS weighed 3700 pounds. It had a generousness amount of aluminum used in it. The 4.0 V8 was light also. Mustangs just have an aluminum hood.

My point exactly, your 2008 vert with NO spare tire, no blower, no jack, and 18" wheels is at 3650lbs, a 2013 GT500 is at 3871lbs, based on rumors that the 2013 RS3 is 300lbs, that would put the 2013 RS3 79lbs lighter then your 2008 Roush GT. I would love to know how Roush is abled to get their 2013 RS3 lighter then a stock 2013 Mustang GT without any weight deletion but instead adding a bunch of go fast parts and big wheels.

Maybe your stock gt weight is off. I dont need weight info when we have.several members that have both and say the Roush is funner to drive

[walker2t]

my neighbor across the street sold his Shelby cobra vert. which he very rarely drove and bought a used 2008 roush after looking at my car for 2 yrs lol he loves the roush 10x better.... I see him grinning ear to ear every time he comes home..which I do see the roush getting out of the garage daily!!!! .. he must drive it like he owns it because the other day I seen he had it jacked up and I walked over and asked what's wrong, nothing I'm going to kill myself in this thing putting 6 piston roush brakes on... lol another satisfied customer!!!

Stock GT weight is from Ford, I doubt if Ford is off on its own curb weight. Yes several members have said Roush is a better car and lighter car then the Shelby GT500 and I am one of them. The problem is most members here have based their 4.6L Roush against the close to 4000lb 2008-2012 GT500 which the 4.6L has an advantage of 300lbs. The 5.0 Roush gained significant weight over the 4.6L Roush because of the 5.0 plateform, there's no question the 4.6L Roush is lighter then the 2013 GT500, heck its even lighter then the 5.0 Roush, but my doubt is still the 2013 RS3 300lbs lighter then the 2013 GT500.

I didn't mean exactly 300lbs. Just close to it. mid 200's last compare I saw. The big thig is the hard evidence on real world track times. If you see those links, the 2010 Stage 3, which we tested with 508 rwhp, had an 11:56 when tested. The GT500 when tracked in the other link had an 11.8. Gears and weight are the 2 main differences, so something is up.... just trying to say, both cars are fantastic, but everyone likes to put the two up against each other. The cool thing is, they are both comparable in many ways and best of all, they can both blow away a ZL1 with a "Best time of 11.96 when Chevy ran them.... that links on there too I believe.

Both 2013 Mustangs are great and you can't go wrong with either, but I think those numbers are more for the 2010 Stage 3 with the 4.6L which has an a weight advantage over both the 2013 5.0l RS3 and the 2013 GT500. A fair comparision would be the 2013 5.0l vs. 2013 GT500. As for the 2010 Stage 3 hitting 11.56 and the 540R 1/4 compared to the 2013 GT500, I take that result with a grain of salt. The 2013 GT500 1/4 time is based on street tires and obviously test drivers from MotorTrend, CarandDriver, etc.. are not professional drag racers compared to 5.0 Magazine, Mustang Mag, and Street Legal, plus the 540R had drag tires. Car and Driver test drivers are road course specialists, in their hands on street tires, they got a 13 flat for a 2010 4.6L 427R, yet in the same hands they achieved a 11.7 for the 2013 GT500, obviously the 2013 GT500 had the advantage due to its launch control and the truth for both cars is somewhere in the middle, but its the fairest comparision since both cars are in tested by the same magazine and more importantly with street tires.

i think scarface has a valid question...but at the end of the day it is all about choices....these cars are both awesome mustangs..period...in a drag race the GT500 should be able to pull away from the RS3 at some point mainly due the fact it has a 5.8 liter engine vs the high reving 5.0...however no one is saying much about the suspension? since Roush is not adding as much to the suspension as in past years and it seems the GT500 got some upgrades in that area where does that put both cars on a road coarse? does the extra weight of the GT500 slow the GT500 or does the new suspension save it? does the 2013 GT suspension and the new Roush package still give Roush the advantage or is the Roush not as great on the road coarse as it once was? either way i think the battle should be with the new LS1 camaro or any other GM, Mopar or what ever challanges the mustang...both the 2013 GT500 and the 2013 RS3 are the best cars Ford/Roush has given the public in many years and the future looks bright if they can continue to improve...until there is an honest to goodness battle royale either between the GT500 and the Roush or the Mustang against what ever, its all speculation at this point...i for one will be cheering for the Roush but if the GT500 can make Ford the top dawg, so be it!!...cheers...

Good point. I am hoping people understand I am not bashing Roush, I am just saying that Ford has taken a huge leap from the previous GT500 generation to the 2013 GT500 while Roush has been more like a cookie cutter. We all know the previous GT500 was nothing more than a pig with a Shelby badge and to keep comparing any Roush to the previous generation of GT500 and using it as a measuring stick for the 2013 GT500 really does a dishonest to the 2013 GT500. At then end of the day, its a win win for Roush owners, if the 2013 GT500 manhandled the 2013 RS3, hopefully it will force Roush into creating something little more special instead of just slapping go fast parts. History has been provened that Roush likes to sit idle with their graphics dept for new graphics and whenever they get kicked in the rear end, they will release something special.

Trinity laying down 600 to the wheels bone stock..........Time to step up the game Roush.(or at least get back into it)

[429R#5]

I agree with Scarface and would like to get some real world numbers on the weight of both cars. Keep in mind that in 2011 the GT500 switched to an aluminum block that dropped ovet 100 pounds from the nose and it handles a lot better than the 2010 iron block car. The 2013 5.8 does add some more pounds to it but i can't imagine it would be near 300 more than the Roush, more like around 200. I actually traded my 2009 429R for a 2011 GT500 SVT PP and I really like it. I can tell that it is heavier than my Roush was but in all honesty I do not track my car and for a daily driver it gives me all the fun I want with the styling and power I like. The SVT PP suspension is really great and it will make just over 1g on the skid pad. As everyone has said, both are great cars and it really comes down to how you plan to drive yours and what you like the best. Heck, if I could have afforded it I would have both now!

[Pentalab]

Both 2013 Mustangs are great and you can't go wrong with either, but I think those numbers are more for the 2010 Stage 3 with the 4.6L which has an a weight advantage over both the 2013 5.0l RS3 and the 2013 GT500. A fair comparision would be the 2013 5.0l vs. 2013 GT500. As for the 2010 Stage 3 hitting 11.56 and the 540R 1/4 compared to the 2013 GT500, I take that result with a grain of salt. The 2013 GT500 1/4 time is based on street tires and obviously test drivers from MotorTrend, CarandDriver, etc.. are not professional drag racers compared to 5.0 Magazine, Mustang Mag, and Street Legal, plus the 540R had drag tires.

The only way to know is to drive onto the scales. I think the ford quoted weight is with an empty gas tank, and nothing extra in the trunk. and no driver or passenger. For motorbikes its no fluids at all.

I bought a new 2011 Ford Fusion lasy year. It comes in 7 versions. Everything from a 2.5 L 4 cyl.. to 3.0L V6 to 3.0L AWD.. and then a 3.5 L AWD ( hot rod version)... and also the hybrid..with a ton of batteries below the rear seats. ALL 7 x versions were listed last year on fords site
as ...."3400 lbs"
Well obviously they can't all be 3400 lbs ! I mean like how can a 2.5L FWD be the same weight as a 3.5 L AWD. The hybrid is heavier than all of em.
The weights listed on all these cars is out to lunch. A 2008 shelby rag top with a full tank of gas and 2 x people is typ 4560 lbs. Without putting any of these cars on the scales, I wouldn't believe any of it. Give me the weight of the car, with a full tank of gas.. and zero passengers, and no driver.

Curb weight of the Mustang and GT500 are really simple to find unlike Fusion with 12,000 variations. Ford list the GT curb weight seperately for auto, manual, V6 and v8, Vert, GT500 comes in only one flavor. Curb weight can also be found on various magazines from MotorTrend to CarandDriver which actually weight their cars and their numbers are only a few pounds off. For example, CarandDriver weight a 2010 427R 4.6L at 3700lbs, one of our members had his car on the scale and it came in at 3680lbs, the difference of 20lbs can be with a full tank of gas, tires, wheels, etc.. but a 20lbs difference is on par with the average.

[whtstg3]

Me. 80lbs more than my Trak Pak was.

2010 Stage 3 from MMFF
While we loved the handling aspect, the Stage 3 really shined on the 1,320. Editor Smith was able to knock off a slew of 1.90-second 60-foot times and 11-second runs, the best in stock trim being an 11.572 at 124.78 mph.


After a cool-down period using fans to cool the blower and a tire change to Mickey Thompson drag radials, Smith pulled off an 11.538 at 124.13 mph with a 1.875-second 60-foot. We knew there was more left, so we dropped the rear tire pressure from 22 to 18 psi and plugged in the fans for a longer cool-down. After a quick tire heat-up, Smith launched the Stage 3 and ripped to an astounding 11.402 at 124.98 mph, thanks to a 1.74-second 60-footer.

I love this video and also the one with Jay Leno going gagag over the 2013 GT500. I also see "Ignition" listing the 2013 curb weight at 3871 which is on par with Ford's curb weight. I also called Future Ford whom I do a lot of work with for and throughout the community, they are also the largest Roush dealer in California, I asked them the curb weight on the 2013 RS3, like many Ford dealers, they said the "starting" curb weight is 3618lbs (manual coupe), that's before the blower, wheels, brakes, and whatever else Roush throws onto it. I will see if they will lend me a RS3 for a day and I will find a scale to throw it on.
