    The 2019 Corvette ZR1 - 750hp LT5

    Here it is folks. This is 100% real. The car is officially revealed by GM on Sunday.

    So the LT5 is a blown 6.2L that's just got a bigger blower on it than the LT4. Hm...

    A thread on corvetteforum said it has either the 7M or an 8 speed automatic. Why wouldn't it have the 10spd? Or is that perhaps wrong information?

    Corvette won't get the 10 speed in this generation. Since we're about a year away from the C8, there was no point in engineering the A10 for the current Corvette.

    The aero bits are pretty loud, but overall pretty badass.

    If it's that soon for the C8, I'd pass on buying this car (if I were in the position to get one).

    It takes some getting used to from some angles, but I like it. I like that you can opt out of the mega-wing too.

    The front edges are problems for me, but I know damn well that it needs the air flow.

    i'm not big on the new corvette but i don't think the ZR1 looks bad. better than the regular vette for sure.

    not a big fan of the wheels though.

    750hp... Not bad...

    Let's do some quick mathulation here...

    Demon... 840hp... 4280 lbs. = 5.09 lbs. per hp.

    ZR1... 750hp... 3772 lbs. = 4.96 lbs. per hp.

    GM should have a drag radial package and a transbrake as an option and put the Dodge on the trailer, just for giggles.

    Wouldn't the aero bits on the ZR1 slow it down though compared to the nothing on the Demon in a straight line?

    Thinking the current joint Gm/Ford 10spd may not be beefy enough to handle that kind of power.
    But, I've never seen specs on it.

    It's handling 650 on the ZL1.

    My guess, to go with the rumors I heard, is the 10 speed was designed after the C7 chassis and it won't fit.

    I think ricers of the late 90s/early 2000s ruined wings for an entire generation, because that's what so many people think of now when they think of spoilers/wings. To me, seeing a car with a functionally necessary wing is no different than seeing a car with oversized brakes, or a supercharger scoop sticking through the hood. It's a functional piece of go-fast hardware and it's cool, IMO. A corvette like this isn't supposed to be a sleeper or something... it's a street legal race car.

    would a 10spd even benefit a car like this? 750hp is probably enough power to spin the tires at anything below 100mph, so is added gear reduction and torque multiplication even much of an advantage?

    Yep... IMO, it's the Corvette's version of the Viper ACR.

    I'm kinda surprised they kept the red tail lights. Figured they'd be clear, like the ZO6.

    Functional or not it still looks clapped out.

    What happened to the big HP NA DOHC engine???

    For me, it depends on the car. If I see some clapped out 5.0 Mustang with a giant wing, my eyes roll around my head twice. If I see one on this car or a Viper or any actual track oriented car, I give it a thumbs up because I know it's functional and not stuck on by some douchebag trying to make everyone think their car is fast.

    Agreed. It actually sounds like it has better manners than the ACR though, which is a good thing.

    You think a factory NA platform would have produced anything near 750 hp? Be pretty silly to put an engine in the flagship ZR1 that couldn't compete with the ZO6.

    Maybe not 750HP but 700+ would have been possible from a 7.0L DOHC.

    Meh... That would take a lot more time, engineering, and resources simply for a car that won't be around that terribly long before a new model will be out. The current design is cheaper, makes more power, and reaches a performance goal much easier.

    GM: "We want 750 hp out of this engine."
    GM: "Hello Eaton... we need a bigger blower."
    Eeaton: "Done"
    * GM: "Ok, we have the blower. Let's beef up the internals"

    VS coming out w/ a brand new engine.


    *I'm only assuming here.

    Sure...but a stock Z06 is more car than would realistically need for handling, so form > function for me.

    Your Demon numbers are off because 840HP is on race gas and the 4280lbs it the gutted car nobody will order. Real world the the ZR1 has a bigger lbs/HP advantage than this.

    I'll give you the weight, but why do you get to discount the power it will make from Dodge by just putting the right fuel in it?

    Can you fill up with race gas at the Quick Trip or KUM & Go when you are out for a Cruze in your Demon?

    Maybe not, but you sure as hell can fill up from the barrel in your garage.

    Sorry, but I thought we were talking about maximum effort racing. You know, like how Pacer mentioned it would be great if the ZR1 came with a transbrake? Oh, wait, it doesn't.

    Best bet is for any non-Demon fan to leave the Demon out of a comparison with any other production vehicle.

    I wonder what the drag coefficient is on the Demon VS the ZR1. I know the ZR1 has a ton more downforce, but I still would be curious to see the comparison (not sure why we're comparing these 2 cars anyway. The ZR1 is made for so much more than just the 1/4)

    Tell us all again why you need a DOHC engine to make power and go fast? I'll take the compact, lightweight pushrod engine that still makes tons of usable power (as much of more than any DOHC V8 Ford has ever made), is simpler to produce, and had less internal friction. 8 and 10 speed transmissions largely nullify any benefit of an increased redline in a DOHC engine.

    It's not even close to be a drag car. These 2 cars are on complete opposite ends of the spectrum.

    Not to mention the fact that it was more cost effective due to the fact that they didn't have to design and engineer an all new engine for what will be a 1 model year only, extremely low production vehicle.

    If we see a DOHC motor, it will come with the C8.

    What does this have to do with Ford? The orginal ZR1 was DOHC and there was a good amount of speculation about GM coming out with a bespoke engine for the new ZR1.

    Who cares about that? Ricers?

    And this ZR1 tracks closer to the most recent ZR1. Those speculations were just BS, clearly.

    I think the point is that this 750hp platform is not a let down compared to some fantasy DOHC concept. You brought it up as some kind of negative and that just doesn't make any sense to me.

    Like CT Morgan pointed out, you're trying to make it some sort of negative that GM still uses pushrod engines, or that they should have used a DOHC engine in this car because some random bullshit story said they might. I'm asking you to tell me why?

    Cause something like the Voodoo engine is unique and makes 100 hp/l NA and revs to 8000 plus rpm! Just hope it holds up.

    I swear, some of these guys would want crotch rocket engines in their cars.

    Read my orginal post...I'm negative on the style and mentioned the that DOHC speculation clearly did not happen.

    Would I think think car would be cooler had GM saw fit to create a monster DOHC....for sure.

    Drag coefficient wouldn't matter without knowing frontal area.

    If I remember what I read, there are multiple levels of aero available on the ZR1 also.

    Well...

    We know the ZR1 will hammer the Demon in any other performance metric, so it would be snifty if it hammered it in the 1/4 too.

    Why are you trying to compare these two cars in the first place?

    Incorrect. The original ZR1 was a pushrod LT-1 in 1970

    Why would it be cooler? What does cooler mean? Like literally cooler as in engine temps?
