I just can't keep up, that new 6 speed auto I just bought is already out dated lol. They got 7 speed manuals and 8 speeds autos now what's next?

CVT.

That new Corvette is pretty nice, but the 707 HP of the Challenger Hellcat still blows it away. I keep wondering when Chevy is going to release a new ZR-1.

Chevrolet says Corvette ZR1 not under consideration

"Introducing a ZR1 halo car above the upcoming Z06, which is due at the end of the year, would require significant investment in design, testing and certification – for negligible performance gains. It appears that Chevy is choosing to focus on the Z06 for now, and wait for the next great technological leap before investing in another ZR1."

Wonder how these manufactures get away with these cars going so fast without roll bars ect?

The selfish greedy scumbags at the NHRA have already been forced by Detroit to lower the roll bar standard from 11.99 to
11.49 a few years ago. So that is a good question.

I guess I don't understand. How is the NHRA "selfish" and "greedy"? How did Detroit force them to change it?

In order to put money in their pockets and their sponsers cars must have new seat belts every two years, must run SFI scattershields flywheels flexplates dampners ect and they must be recertified by Mfg or replaced every five. With new cars dipping into these rule zones, example rollbar, they lowered std. Basically they help fund the pro series races on the backs of the sportsman racers. Ask anyone who has races a 10 second or faster car in recent years.

Am I missing something, the Dodge has 10% more power

This is what Chrysler says the Challenger does, and the Corvette does the 1/4 in 10.95 with no mention about the tires.
"2015 Dodge Challenger SRT Hellcat: The Fastest Muscle Car Ever With A 1/4-Mile Elapsed Time of 11.2 Seconds (10.8 Seconds with Drag Radials)"
http://media.chrysler.com/newsrelease.do;jsessionid=12B8F2FB295CF16D69A302B4 AD3616B4?&id=15790&mid=1

Challenger does 0-60 in 2.9 sec, and the Corvette does 0-60 in 2.95

I wouldn't say that the Challenger blows it away, especially when you consider the power difference, but I guess we will have to wait for a head to head. I think I would be more interested in how it performs against the other sports cars on a road course.

What I meant is the Hellcat blows the Corvette away in brute horsepower. The Challenger probably weighs quite a bit more than the Corvette, as Chevy has really focused on weight reduction with the C6 and C7. And the Challenger Hellcat is a lot cheaper car, $60K versus $80K. IMO the Challenger is a great looking car.

I don't understand why Chevy says they need "new technology" for the ZR1. All they need to do is take the LS7 (7.0 L) and put a supercharger from the LS9 on it. I think it could easily go well over 700 HP and all the parts exist NOW. The LS9 at 6.2 liters is 638 HP and just scaling by cubic inches gets you there.

The Hellcat is a supercharged 6.2 liter engine at 707 HP. The LS9 is a supercharged 6.2 liter engine at 638 HP. Same engine size, but Chrysler wins. Why can't the LS9 do 700+ HP?

"So far the EPA has only revealed the SRT Hellcat’s highway fuel economy, which checks in at an incredible 22 mpg with the eight-speed auto and 21 mpg with the six-cog manual."

Pretty amazing for a 707 HP car at about 3834 pounds. The C7 Corvette is almost 600 pounds lighter at 3252 pounds.

CN are those curb weights? Most of the Challenger guys I know say their cars weigh 4300lbs. Takes a lot to move that!

Jt, yes I believe those are curb weights. I got them off the internet, which doesn't mean they're right.

Here's the spec from Dodge. The SXT models are 3834 pounds and the RT models are 4082 pounds. The SRT and Hellcat are 4160 pounds.

The hemi heads probably account for some of that. There is no question that GM can get the HP up there, but Chrysler expects their hemi to be king again, and at some point big brother is going to step in.

I have been told these so called Hemi moters are that in name only.

That probably came from some Chevy guy who doesn't know what a Hemi is. ;)

The Hellcat has two spark plugs per cylinder. It's a hemi(spherical) combustion chamber design as far as I can tell. It's actually the 392 Hemi de-stroked from 6.4 liters to 6.2 liters.

Hennessy has a 717 hp Mustang now.

I'll bet someone is working on a 727 hp Corvette or Camaro. Even if the factory isn't.

My guess is that either the insurance companies or the gov't are going to put a halt to all this and it will be 1974 all over again.

At the dentist's office today, I read in Oct 2014 Motor Trend magazine a head to head with the Hellcat and ZL1 Camaro. They both had some points better than the other, but of course the Hellcat won the best muscle car in their opinion, and biggest attention getter. I'm bias but I like the looks of the Camaro better, but its hard to deny the appeal of the hemi.

The drag strip times were interesting, especially when you read at the end of the article that they put both cars on a chassis dyno, then figured from those numbers what the flywheel HP should be. The Hellcat figured at 727 instead of 707, and the Camaro somewhere around 540? don't remember for sure, instead of 580. They had the same kind of tires, and the Hellcat had to start off in 2nd, which as I look at it now, its probably unfair for the Hellcat. They should both be able to hook up, they also had different superchargers, but I don't know about the gearing. This is what I found on line about it, but the mag article has a lot more in it.

I saw a copy of the Motor Trend Oct issue in a drug store, and a correction is in order.
When they figured the estimated flywheel HP from the Dyno results, It was 722 and 524 estimated at the flywheel.
