JVP knowing as much as you do about the car industry how does McLaren get away with that? As you mentioned it's pretty common knowledge that when you put one on a dyno they make almost 700rwhp so yes it's basically an 800hp car. How does it get by horsepower certification tests?

Is it simply they say they have way less drivetrain loss? I'm genuinely curious.

I don't believe they're working to the same SAE standards that companies like GM are. So they can make whatever HP claims they want with little fallout.

Ah interesting! Thanks

This. 100% assuming every single factor is completely equal.
However, in roll racing, it never is. Even a mostly imperceptible jump will give a big advantage when cars get this fast.

At the strip, on the highway, and in Mexico, the 720S will win. DragTimes and several others have made countless videos on the animal, that is the 720S. There's nothing that runs with it there.

But the videos I saw of the M7 ZR1 vs Demon, the ZR1 annihilated it, especially if they started even. When the Demon got the jump, the ZR1 still pulled it good after a gear or two. Within weeks, one of the first passes of a ZR1 owner at the strip with DR's put down a 10.1 with an A8 ZR1! The Demon has been in owners hands for months and months now, so far, most owners are running high 10s/mid 10s, only ONE has broken 9s and only 3-4 have run 10.1 or better. The ZR1 beats the Demon in every dimension. The Demon is such a useless one trick pony, IMO it's a total failure of a vehicle. Dodge needs to get back in the Viper business and build something worth buying again.

But back to the subject at hand, I believe the 720S would beat the ZR1 in all situations, not just straight-line. It's not like most American cars. The 720S doesn't sacrifice track performance for straight line speed. It is very light, active aero, great suspension, low drag, and is every bit as good or better than the ZR1 in every category, HP, brakes, transmission, weight, aero, etc. I know it looks like I'm hating on the ZR1, I'm not. I think the ZR1 will likely set the production car record at many tracks, other than just VIR. But the 720S hasn't released a 'Ring time or any others that I'm aware of, at least ones that are important. I bet you the 720S will run with a P1 on a track, and if that's the case, the ZR1 will have a helluva fight at the track. On the highway or at the strip, it won't be close. This is what you get when you spend $350-$400k on a McLaren, they're monsters, not easily outdone. And yes you could buy 2-3 ZR1's for one 720S, and yes, likely full bolt ons will make the ZR1 run with a 720S on the highway/strip. But the 720S, in my opinion, is also 2-3 times better, not just in performance but in aesthetics, appeal, and satisfaction.

If one was rich enough to buy a 720S with ease, then I doubt they'd ever consider a Chevy Corvette. I'm seriously considering selling off a few of my Chevy's and getting a 720S or 488.

Oh by the way, Mike ran his 570S against his ZR1. The 570S beat it nicely. The 720S is quite a bit faster than the 570S.

I like the 720 a lot. Recently, I've begun to hear rumblings it might not be screwed together very well. Which is a real shame given its performance.

Enzom

Closer to 147 mph

I am 100% certain that Brooks from Dragtimes will set up a race soon.

Enzom

The only rules of which I am aware as it pertains to engine power make it illegal to overstate the car's HP. But not the other way around. That's why Mazda had to buy back a bunch of RX-8s years ago.

URBAN LEGEND

Is that the guy with the 720S all over YouTube?

Can'tHave2MuchHP

The orange one that races everything? Yes, probably him.

Teething pains are sorted out. Knock on wood, mine has 3,000 miles on it and is running great without any of those fault lights popping up like others have had. My 650S spider only had a (very, very expensive) battery malfunction that was replaced under warranty a year and 3,500 miles into ownership. I did not have my 570S for very long, but that car needed new door latches. A design flaw.

They don't run like Porsches yet, but they have come a long way from 2012/2013. I am really enjoying mine.

Enzom

Yup. He spends alot of time in Mexico

Enzom

By the way - pretty amazing that people want to see a race between the ZR1 and the 720S. Says alot about how fast the Vette is.

I was never able to keep that traction control light from flickering in my C7 Z06. Even with winter tires on during the fall and early spring, I don't think I was able to get one great pull to 120 mph from a roll. Lost a lot of informal "races" I should have won.

OnPoint

Enzom - good hear on them getting the 720 sorted.

Gorgeous color on yours, btw.

thegame

Yea but to be fair that was on a pretty cold day and the vette didn't have as much traction as the mid engine McLaren. Also I am not using Mikes ZR1 as an example of the ZR1's performance because it is an M7 and no offense to Mike he is no Randy Pobst. I think an A8 ZR1 beats a 570S in temps that are not cold enough to ruin its chances. Just my opinion and I really have no horse in this race. I have a modded GTR so I don't really care which is faster lol

URBAN LEGEND

Heck yes. ZR1 has the hardware to play with the best.

URBAN LEGEND

Ok. That dude crushes most challengers.
I don’t see him putting bus lengths on the A8 ZR1.

Can'tHave2MuchHP

Funny enough his buddy "Send it Steve" was driving the ZR1 and he's a better gear-yanker than Mike. His shifts were good, watch the video. Traction, sure, always going to be a weak point of the Vettes design. An A8 vs 570S race would be a lot closer for sure, if they both had traction, I could see the ZR1 beating it in the mid range. Launching and top end, I see the 570S being stronger. Goes without saying that the 720S is much faster than a 570S.

Kappa

From Car and Driver's latest test of the 720S:

0-60: 2.7
0-100: 5.3
0-150: 10.9
0-180: 17.5

1/4: 10.2 at 145mph

Safe to say, its running away and hiding from anything other than hyperexotics(P1/LaF/Chiron/etc.).

The ZR1 does its best damage from 40-130mph IMO.
