Today is going to be a pretty busy one for those with a huger for 2020 GT500 news. Last week Ford held its first official Press Drive for it's latest Snake Car in Las Vegas. Those in attendance were sworn to secrecy until today. In this thread we're going to try to aggregate all the best articles and videos in one place for you to enjoy:

Yeah. No data = don't care.

Cool. Stand that ground.

A lot of us get the writing on the wall.

* I can understand a position of:
-was it factory tires?
-was it pump gas/stock
-was it a kr prototype test or so on?
-was it a shortened version or Sam’s as the viper’s run etc

So yes I get that you could be saying don’t count chicken until they hatch.

If it was GM with their history of over hyping like the “11’s” in the gen 5 zl1 that had drag radials, closed track, prepped track etc or the nurb run 7:42 on slicks, etc ya I’d say I’m not buying it.

Ford said it runs sub 11’s, it did. Mid 3 0-60, so far I’ve seen it go 3.39 on the street with two people in it over 200lbs each meaning with my 175lbs skinny ass, it has a 3.25 in it imo, etc.

Ford said the 2013 would do 200mph, it went 196 on a somewhat small oval at altitude in Vegas I believe. It went [email protected] in a handful of places, etc.

Fords had their time in the barrel with the 99 cobra and 07 gt500
 
Every review I've read or watched has been nothing but amazement at what Ford did with this car. Only halfway negative commentary is that it's got a Mustang interior. Seems like the car is great at everything, 1/4, road course, and streetability.... seems like a grand slam.

The 2020 Ford Shelby Mustang is a savage, daily-driver muscle car – TechCrunch

Driven by Matt Burns who is a managing editor at that site since 2008.

Author: <span class="vcard">Matt Burns</span>

That’s at least 3 10’s north of 130 in bad conditions, headwind, hot cars, etc.

It’s a solid 10 sec car.

It really does seem to be getting rave reviews. Also echoed is how it as well as others are last of a dying breed as the market shifts towards electric. I wonder how soon that happens for these level cars, I also wonder dodge in its seemingly competitive nature in recent years, would they have at all a formidable answer to this GT500 or will they keep with their bread and butter?

.but it is hilarious to come up with laptimes based on a video.

That is a somewhat foolish statement. Videos run at specific speeds and if playback is proper, time will run as accurately as if you were seeing it with your eyes. The only factor here is the person watching the video and starting and stopping the clock. Even factoring in some delay by said person hitting the buttons, it's logical to assume that delay would be the same for start and stop. Thus, the resulting lap time is almost certainly within 0.5-1.0 seconds.

It's not black magic.
 
one thing I got from the reviews is that the CFTP does not ride harsh on the street like the ZLE. So if it puts up ZLE track numbers with a GT car ride, like the 350R did vs the Z28 that is another testament to the Ford engineers ability to deliver a well balanced vehicle.
 
It is bench racing at its finest.

Some people seriously think that the '20 GT500 is faster around a road course than a Viper ACR LOL

Gt500 cftp has better brakes, trans, lower c/d, lighterwheels, more hp, more average and peak torque and most importantly bigger exhaust tips.

Viper acr-e has 1700+ lbs of downforce at 175mph. 3350+1700 is 5050lbs at 175. It’s about 1200lbs at 100 iirc so 4550lbs effectively.

Gt500 cftp Probably has 300lbs at 100mph so 4375lbs. It has 115hp on the viper, and is effectively 175lbs lighter at 100mph. By 125mph the gt500 is probably 350-400lbs effectively lighter with the same 115hp advantage and I’m not even getting into torque though I should since gearing favors the gt500 being 3.73, same 1:1 forth vs 3.55 rear in the viper. Factor redline and power band, and the Ford has double the rpm to work with. Exit in 4th instead of 3rd in the viper and you’re killing potential. Look at their dyno graphs.

The gt500 cftp has a low center of gravity for a 4075lbs sc car because of the dct and inverted sc, carbon composit cradle, etc. it has 550lbs at 180mph so [email protected]

My point, anything over 100mph is going to the gt500 short of a 1.3+ g corner as the acr can hold almost 1.5g’s. That means it has the potential to hold more speed, if it can reach it to hold it. Problem is it’s accelerating at a lot less g force in a straight line. The car can hypothetically hold let’s say 175mph on the tight side of an oval, but it only reaches 145mph on its way to that corner. The gt500 can only hold 150mph on that same corner, but it reached 160 on its way there, and actually slowed a bit (hypothetical comparison)

My point is above 100mph, the gt500 is likely faster overall. It also effectively weighs less, has lighter wheels and bigger brakes so braking may not even go to the viper at very high speed.

The viper acr should have the advantage at low speed but crucially, it’s manual vs dct so the driver has to be flawless at pairing engine speed to cornering speed while balancing traction. He could nail the corner but be in 3rd at 65mph and slip far back before the next corner as the gt500 exits that same corner at 58 butis in 2nd and blows past to the next corner.

Some tracks the gt500 cftp will be as quick or quicker. I’ll go on the record. High speed tracks will be the gt500’s to lose. A place like vir or big willow for example will favor the gt500. A place like leguna is the acr-e’s all day.

Something tiny like limerock could actually go to the gt500. Between the dct/manual and wheel/brake difference, the gt500 will actually be formidable at low speed stuff. The acr-e shines in areas from 60-120imo.

It’s best lap times are at places like leguna. It’s worst are at tracks like vir

My opinions. I’m just a bench racer that happened to guess the gt500 would hit [email protected] 3 months ago.

A track pack gurney flap gt500 with the regular wheels will be far behind a viper acr-e. Ford went nasa on this project. The weight is a non issue

Well watch the video of the ACR's lap at Grattan. Its bouncing and bumping around like a trophy truck. The acr relies entirley on mechanical grip. The new 500 has an entire generation of new tech that helps overcome that. I was saying earlier that wont happen on ANY world class track. I wouldnt be surprised if the 500 is faster on Sebring too.

Should also be pointed out that the 500's bespoke compound of cup2 is "not slower than ANY aftermarket tire you can throw on" so.. Most other cars will have an aftermarket advantage whereas this 500 is likely entirely tapped for lap times on the RC

Interesting post. To start off, what do you mean by "better brakes"? Are you talking about 60-0MPH distance, the feel of the brakes, or the size of the brakes. Given that you never driven the GT500, how could you possibly know if it is better?

So, how many track days have you done this year? There is a lot of speculation on how the Viper ACR and GT500 drives in your post. Obviously you haven't driven the latter. Have you driven the ACR before? I did - both at Mosport and Watkins Glen. The thing I loved the most of the Viper is the confidence to take corners at a much higher speed than you are used to and being confident in the aero and mechanical grip. It truly is a race car for the street in the purest terms.

Maybe he stayed at a holiday inn express?
I thought his reasoning and explanation was spot on. Whether the engineering and real world physics back it up is something else. Better than the 13 GT500/GT350R/ACR? It should be better than all 3 as especially for the last it has so much more weight to pull back. Will it actually outbreak the ACR? Who knows but all those who drive this car says the brakes do far more than they believe or realize.

I thought the 20 GT500 would outrace the zl11le but fall short of the c7z. Then we heard comparisons to the z. Now we hear dominating times over the z comparing to the ACR. Wow! Holy Ballz Wow! Never expected that.

I think he’s right some tracks it will compete or outrun the ACR(1 lap/short 20 min session) and other tracks the ACR would still cruise. Reports from those who have driven both on track and the 20 GT500 back this up.
 
Bench racing is fun but I really hope they get the new CFTP GT500 with some heavy hitters to run at the same track/same day/same driver. Ideally a Pro and a good amateur.
Still, we all know from media guys that actually do drive all the best cars that this 500 is exceptional.
Majority of us buying them aren’t making our decision based on comparative track times, so this is just fun bench racing.
Looking forward to the comparison vids like a head-2-head.

1. I would buy a viper acr-e before I’d buy a gt500 personally. That said, I would be buying both within a small window of time. One is a beast the other is a jeckle hide car. I’d drive a gt500 more often but have more fun in the viper on back roads I think. I also love the c7 zr1 with a manual. I would love a new gt500 with a tr6070. I’m old school but call it as I see it.

2. This is all bench racing, and opinion. I said that already. I’ve driven a few cars on track. I’ve driven and riden some nice cars on back roads. You have more real world experience than me. Guaranteed. These are my opinions and thought. Already stated so.


Braking:

Better potential to decelerate speed as a system. Much better potential to shed speed over shitty surfaces.

16.5” rotor is a huge swept area. The rolling stock is crucially ~5-10lbs lighter per corner. The downforce may negatively effect braking of the acr at speeds above 100mph compared to the gt500 because the car is effectively heavier by hundreds of lbs with smaller 15.4” rotors to alleviate the stresses while working on woahing about 60lbs of additional unsprung outboard weight. Edit 57lbs*

Viper acr: Front tire is 27lbs, rear is 41lbs. Wheels are 26/27.8lbs

Total unsprung outboard weight is 243lbs.

ACR Wheel & Tire Weights

https://m.tirerack.com/tires/Spec.j...utoYear=2017&autoModel=Viper+ACR&autoModClar=


The gt500cftp: front tire is 29lbs, rear is 30lbs wheel are 17lbs each but let’s say .25 heavier for both rears (doubtful). Total unsparing outboard weight of 186lbs.

https://m.tirerack.com/tires/Spec.j...ustang&autoModClar=Carbon+Fiber+Track+Package

Now take into account the stability and forgiving nature of the mag shocks vs fixed shocks on uneven or bad surfaces while braking. Advantage cftp. Knuckle geometry and front clamping is also all redone for the gt500.

But how often do you perform 60-0 stop on a circuit? How often do you perform 150-50 range stops? The viper has a much better 60-0 number, but that’s as useful as knowing a gt500 can go 5mph faster. Big whoop. You’re never gonna see either of these cars going less than 30 or more than 175 on almost any track scenario.

Let’s move on to acceleration.

Here is a 460hp mustang gt10a acceleration data.

Here is viper acr data
B4915AA6-A578-44A2-BE3E-7693BAD79942.png


A 460hp mustang gt is only 1.7 seconds slower to 150mph than a 645hp viper acr... let that sink in. Effectively the viper acr is slow above 125mph. It’s only 6mph faster in the 1/4 mile than a gt. The gt500’s are going 133 already and I bet we’ll see 137 before too long. Lop 3-4mph off for cftp cars.

The viper can hold 1.5 g’s. The cftp can hold 1.3 g’s. At leguna or similar medium speed (50-125mph) very smooth, wide tracks, the viper is best suited. You also need to be a great driver.

In average hands, the gt500 cftp is a 10 second car and can keep up with track beasts. That’s ****ing nuts.

Caveats: throw a well programmed dct, carbon wheels, mag shocks and property redo spring rates/knuckles etc in the viper for 16.5” brakes, and although it’ll pick up 300lbs, it will be quite a bit faster. We’ve moved on from mechanical mods like aero and wide sticky tires to the nasa (space organization) esc realm of dual clutch and carbon wheels.

How do you think guys that got model t’s and 32 fords to go 12’s felt seeing a 4000lbs 70 chevelle ss go 12’s with just a tire or guys with 2300lbs 65 Shelby daytona’s felt seeing a 3600lbs c4 corvette zr1 hit sears point etc felt...

Aero not only makes the car heavier but it also naturally slows a car down as well. I have been shotgun in an ACR-E on track with Wei lu from the PWC series driving. Ill tell you one thing. The brakes on ALL of these track oritented cars are 100% dictacted by the tires. Nothing else.
 
I’ve ridden in an acr at moderate driving to about 75mph on back roads as a passenger. Very ridiculously stiff/bumpy, driven one at low speed upto about 40 and also remember it being very stiff. I’ve never been in one in angst, but having also driven gt350/gt350r’s upto about 100mph, and it was stupidly easy to control. On anything but a smooth surface, I just don’t see how the acr would do better than the mag shock cftp gt500 unless the driver is very familiar with the car, and has many hours of seat time.

I don’t like that a gtr can lap as fast and faster than a c6 z06 because I prefer the z06’s experience, and like wise, I prefer the vipers experience, but I think the viper could really excel with mag shocks, and the gt500 would be so much more fun albeit slower with a stick.

Please don't take this as an insult, rather an observation, but based on some of your comments I do think you have fundamental misunderstanding of how aero works.

When you increase the aero load, the springs must be stiffened to compensate, other wise you'd constantly be bottoming out due to the added load. It's not a great comparison, but think about an unloaded pickup truck vs a loaded pickup truck; exponential difference in ride quality. The Viper is built for aero load, not 40 mph, which is where your perception is coming from.
