Default ZR1 seems pointless since A8 not addressed and TCM issues

I dont see the point of the ZR1. With a few mods and running E85 you can be at 700 whp or greater which will smoke the zr1.

the A8 is not addressed which is laggy and has issues. The TCM needs to be tuned badly as throttle closes for no reason because of bad TCM tuning. Guy working on mine says he can fix that.

I agree the Cooling improvement is a huge thing if you track the Car but otherwise its not much improved over the Z06 if you ask me.

I have CCB. I have CUP tires and the car will handle better then 99% of cars on the planet even without the Coils.

Just my 2 cents.

750 hp from the factory in a corvette that laps 2.5 seconds faster than the almighty z06 on the VIR road course and has a top speed of 210 mph and a warranty....and some people are not Impressed..

Some people think critical thinking is synomous with intelligence.

Good luck

I think the point is the ZR1 'factory HP'.

Your points are well taken, but the ZR1 is a factory track car with - HOPEFULLY - the cooling issue solved and 700 factory warranted HP.


The A8 albatross should go away with the C8 which will probably have the A10 or a DCT.

Just get an M7. Problem solved

But yeah, the ZR1 was a bit underwhelming, especially to start at $120k. 295s in the front instead of 285, they fixed the cooling issue, added a wing a bigger blower. This is more like a Tuner Stage 2 Z06 than a different model.


edit: and they added a lot of weight over the front.

I kind of agree with the OP, especially with the $120k base price estimates I’m seeing. Doesn’t seem worth it.

750 factory hp with a warranty and cooling issues resolved for m7. I would guess the A8 cooling issues might have been resolved. Independent Testing will show results when it happens.

The convertible and automatic transmission are for great sales for the street ..


I don't care for the huge wings of either version yet I admire the vehicle and those that purchase one.

I'm sure the performance stock to stock is impressive.

A great farewell to the front engine corvette platform.

Which is probably why it has the wider tires up front.

Isn't that kinda like saying, what's the point of having the Z06 as a separate model from the GS, when you can just add a blower to a GS?

Re: the tires, the C&D article says the front wheels are a half inch wider but does it actually specify the tire width will be 295 instead of 285, or is that a given?

Same 285 tire in the front. But it has a 1/2 " wider front wheel.

Interesting. I wonder why. I just hope they're forged wheels. I'd love to buy a set of take offs.

That doesn't just fix the weight

I feel underwhelmed as I think this should be the Z06 with proper changes to work as advertised. Not a super version. As it's basically a revised Z06 with better cooling and a easy bump in power. Or, what most track guys who bought a 14-16 Z06/Z07 for track duty, thought they were buying. It would be cool if the ZR1 now was an updated 18 Z06 with wings as options, and the ZR1 as a halo midengine. But opinions are just that. I still want one lol.

The z06 is such an amazing machine of course the zr1 would be an evolution of the z06 and that makes the z06 a supercar and the zr1 a super super car..(kidding of course...)

Those who own either will get a thumbs up from me as well as many other corvette owners...

Those who prefer Porsches , BMW s etc may not be impressed but even that should be far and few between.

No one can deny the track performance of the corvette lineup...

It's just a focused performance machine...

Detractors be dammed...very few supercars can match the z06 on a road course....and the Zr1 is 2.5 seconds a lap quicker with the same GM test driver at I believe a VIR course..

That's dam impressive and a great swan song for the front engine corvette ...I expect about 2 and a half years of zr1 production as we most Kelly have both a front mid and rear mid engine corvettes being produced at bowling green...

Hard to imagine GM would make such an amazing machine as the zr1 with only 18 months of production..

They added a wing, changed the fascia, upgraded the blower and improved cooling. Tuners do all that regularly in a few weeks I know they have a lot more to deal with than a tune (I've been on the OEM and tuner side as an engineer), but turning a Z06 into a ZR1 in 18 months is hardly an engineering feat.

The market will tell. I wonder how the Z06 market will be affected. I realize some will be disappointed at this upgrade, but it is still an upgrade and if the price is not sky high it is bound to eat into Z06 sales.

its not all about speed. granted they fixed the cooling which implies the z06 was flawed but it does nothing to address the laggy A8 as the weak point of the car and stock throttle response is very non-linear cause of the TCM and general bad stock tuning. My 8 speed zf bimmer is very linear so why is the z06 A8 so non-linear ? Hopefully after my mods are done that will be fixed.

I would love to know what they did with the A8 on the ZR1.also drove the M7 and didnt like it at all. felt clutch takeup was lousy and had LT. Personally the big win will be when we the C8 gets a DC box.

till then i will wait.

Get notified of new replies

To ZR1 seems pointless since A8 not addressed and TCM issues

Waiting is a good idea for you since you don't like the car and enjoy your BMW ..

I believe the z51, grand sport ,zr1 and z06 are amazing machines.

I prefer the manual transmission but the A8 in all out attack mode is very impressive.

We can agree to disagree...I'm also waiting to see the c8 rear mid engine ..it should be off the chain impressive as it's even better than the amazing zr1..

The greatest corvette has been for years the latest corvette...

This time it is the zR1...

2020 it ll be the c8...

BMW s are nice to..enjoy yours

no i bought the little bmw m235i for my Xroomy and she split. lol

I have a top of line c7 z06 z07 with ccb and cup tires but after driving the bimmer i realized how bad and slow throttle response was on A8.

z06 been in shop for 8 weeks getting full 20k plus makeover to fix laggy throttle and TCM issues.handling is great but not happy with slow laggy throttle which is way way worse on the horse gt.

My point was not sure how the zr1 will address those issues since using same A8. cooling mods are great but i dont track my car so thats a moot issue for me.
