According to a report in Car and Driver, the new C7 Corvette version of the Corvette Z06 will pick up practically where the ZR1 left off. First, they predict it will graduate to being called the Z07; if so, it will be the next General Motors Regular Production Code (RPO), like Z28 and, yes, Z06, to become a model name.

And if you thought a hybrid Corvette was a sharp point of discussion, how about a production version of the small-block V8 with a displacement of "significantly less than 6.2 liters" aided by twin-turbos? That's what CD believes will rest under the hood of the Z07, citing the ever-present concern for fuel economy and the fact that bitumen burners from Cadillac have given up supercharging for turbocharging. The horsepower number is predicted to be an even 600, which would be a 95-hp jump over the current Z06 and just 38 less than the late, great ZR1. Helping to keep control of all that truculent muscle will be larger tires encircling carbon-ceramic stoppers, but CD is mum on other specific changes.

The mooted price: $100,000. This might be the most fabulous new spec of all, seeing as it would represent a $24,400 increase over the Z06 and just a $12,600 undercut of the ZR1. Compare and contrast: in 2001, the first year of the Z06, the MSRP of a 350-hp Corvette coupe was $40,725, the MSRP of the 385-horsepower Z06 was $48,500; if CD is correct, the 2014 Corvette's sea level will be established by the 455-hp Stingray that costs $51,995 and in 2015 we'll be staring down the twin, forced-induction barrels of a 600-hp, twin-turbo Z07 that starts at six figures and that could still be leaving room for a new ZR1 late in the model's lifetime.

      I like everything I hear about the Z06 besides the 100k figure......I think that is way to high in terms of price......I would ballpark the Z06 around 87K and the ZR1 around 132k seeing it be in ferrari territory with what i'd imagine to have blistering numbers........GM is back people....

      The Z06 doesn't need to play in the horsepower wars at this point. That's the ZR-1's playfield now. Forget the power adder, the Z06 is the Corvette vs of Porsche's GT3. All motor, lighter weight and track focused in the same way the Z/28 is the the ZL1.

      I read the "Car and Driver" article and beyond the "Z07" name, I don't think the estimates they made on price, power, and displacement are logical. First, pushing the "Z07" to around $100k is just crazy for a mid-range car. Adding over $24k over the current "Z06" leaves way too much room for the tuner market to undercut the "Z07" with a modified base car with the LT-1 engine. I suspect that a C7 "Z07" will cost about 10%-15% more than the current C6 "Z06" to run about $83k as a starting point. Second, while 600 hp is possible, I think that 10%-15% more power than the "Z06" is more likely, which means a power range of 550 hp-580 hp. Third, engine size is going to be the hardest part to guess. While a twin-turbo V8 is likely in a C7 "ZR-1", finding a balance point of cost versus power doesn't exclude using a 7.0L version of the LT-1 engine, which in fact would make a perfect marketing fit for the "Z07" name. Cylinder-deactivation should keep fuel economy numbers above those of the "Z06" 7.0L engine. However, if the twin-turbo V8 engine part of this story proves accurate, a destroked, high-rev version of the LT-1 (5.5L-5.7L) with twin-turbos should fit the "street-legal road racer" image created by the earlier versions of the "Z06". Because of engine height limitations with the C7 chassis, any engine with overhead cams would be too tall to pass European pedestrian impact regulations, which is one reason why the supercharged V8 from the "ZR-1" will not be used in the C7; therefore, there will likely be no Cadillac engines shared with the Corvette, however the reverse may be true for the future "CTS-V" models. Overall, I will look forward to what the future may bring from the C7 Corvette and how accurate my calculated guesses are.

      For comparison, the original Z06 (for example the 405HP 2003 model year, which wasn't the first year of production) had an MSRP just under that of the new C7 Stingray, and were usually about $51K out the door. The price of entry is now double that. Probably will still be a crackin' amount of performance for the money, but boy has it gotten pricey!

      So glad I invested $15,000 in an 2004 GTO and a UPP Twin Turbo kit good for about 700hp in mild form. Fluffy loves having a back seat, especially to himself.

      Sounds like the TT V8 is a version of the new CTS-V's motor. (Though I hear that the Cadillac will get "only" 581 hp.) I would not bet heavily on it being something other than 6.2L, but we'll see. Also, C&D needs to PTFA: The 4.5L V8 in Elmiraj is not a smallblock, it's a DOHC design based on the 3.6 V6. I quote from GM's own press release on the Elmiraj: "Elmiraj is powered by a 4.5-liter twin turbocharged V8 delivering an estimated 500 hp. The engine takes the baseline technology from the new Cadillac Twin Turbo V6 featured in the upcoming 420-hp 2014 CTS Vsport edition, and expands it to the classic performance format of a V8 engine." And I continue to think that V8 is headed for production in the near term and that somewhere in a locked basement dyno room in Warren is a V12 based on the same architecture. But I don't think it's going to end up in a Vette.

        You can't have a DOHC engine under the hood of a Corvette. DOHC engines are too tall.

          The LT5 Did not come standard in the vette. It was a high price option. Somethink like $75k option in the form a ZR1. which doubled the cost of the vette.And was a lot of money in 1990. The motor was designed by lotus and built by Mercury Marine. Not their biggest hit. Dont think they will go there again.

          I don't know if that's actually true of the C7 and this particular Cadillac engine or not, but I don't see it happening anyway.

      I understand what GM is doing - cut the number of models, better gas mileage, etc, etc. But I would miss the high revving 7.0 LS7. What you will have with a smaller turbo motor is a slightly cheaper, slightly slower ZR-1.

        @wafflesnfalafel
        With the base C7 stepping on the 640 HP SRT Vipers toes already with 455 HP, (as reported in AB last week), I'm going to guess that if the Z07 gets 600 HP it probably won't be slower that the C6 ZR1 I'll also miss the 7.0 if it doesn't return, but there's always the Z/28 to keep the 427 alive for awhile longer

          @nitrostreet
          Again Nitro you missed the point. And the point is if a small cube motor vs a big cube motor both make 600hp the advantage is a smaller cube motor when taking into consideration of a production vehicle in terms of fuel economy. Also in terms of higher and faster revs. Meaning the engine will get into the power band sooner. Granted a bigger cube motor will make more torque if the HP is equal. But I'm sure GM will be willing to miss a few extra lbs of torque. Also you statement about rule changes for a smaller cube motor takes into the fact that the smaller motor makes less HP. Well if they both made equal HP like I'm talking about Then I'm sure we wouldn't see as many rule changes. And we are not talkn bout race cars. Anyways. We are talkn bout stock producrion cars. And yea I'm from the oldschool too. Bigger is always better in my book. But that doesn't mean I'm right.

          It may rev higher, but like I told a guy out at the dragstrip when he told me "Lets see your big-block turn 12 grand!" (Like his was turning) I just looked at him and said "Lets see your small-block beat my big-block" End of conversation

          @Tom
          It doesn't matter, bigger cubes will always be faster with everything else being equal (equal means equal money in both motors, too) sure you can build a $30,000 small cube motor and beat a $10,000 big cube motor, not proving anything other than if you don't have cubes, you better have lots of dollars. RPM doesn't win races, HP and Torque does

          What ur missing Nitro is that the zo6/7 isn't meant to be a drag racer. Its a road racer. Also GM doesn't need a big cube motor to make 600hp. They can do it with a small cube motor and rev the piss out of it.

          Dunno, a 7.0L V8 that revs to 7,000RPM is pretty damned amazing.
          nitrostreet
          • 1 Year Ago
          @Tom
          Still doesn't matter HP and Torque will always win straight line or around corners, RPM will never ever win you a race, the only difference would be if the bigger cube motor weighed more than the small cube motor, and with the 7.0L 427 cube only weighing in at 459 pounds fully dressed, you simply cannot get a lighter, more powerful package, while the weight of say a V6 with dual overhead cams would be a similar 450 or so pounds, a lot of people seem to forget to also add the weight of the twin turbos and intercoolers that a V6 or smaller cube motor would have to carry with it to be even remotely comparable to the 7.0L, and all of a sudden the small cube motors overall weight becomes the liability if you were to try to race a car equipped with either motor. Another thing you might want to ponder too is: Have you ever heard of a race car sanctioning body be it drag race, road race, circle track, whatever, that was faced with having to slow their cars down ever handing down a ruling that required larger cube motors to slow their cars, down? They always sanction for smaller cube motors because smaller cube motors are slower

      I saw a Lime Rock Green one tearing down the road this weekend at a very healthy clip and sounded pretty good too, nice roar. Not sure if you really need more power, the Stingray seems to go fast just fine. Definitely convinced that the rear spoiler should be a delete option after seeing it in the flesh.

      hhhmmmmm.... I don't know about this. I can see GM putting direct injection and variable valve timing on the 7.0L V8 and getting the output to about 560 - 570hp. From what I understand, in very simplistic terms, the current 7.0L V8 is basically a 6.2L small block V8 with larger cylinder liners and different cylinder heads. So taking the new 6.2L DI VVT motor, putting larger cylinder liners and redesigning the cylinder heads shouldn't be too much of an engineering challenge. THEN I can see GM taking the current 6.2L DI VVT engine and slapping two turbos on that to produce close to the rumored 700hp for the ZR-1. If I were a betting man, I'd say that this is how Corvettes engine line up is going to play out. Any ideas out there???

        I agree. The Z06 is made to be the ultimate track weapon and the ZR1 made to be the ultimate all rounder. GM would not implement forced induction in their track oriented because they always have been worried about heat soak. They do have a point and the SRT group has the same argument too. Jumping to the other piece of information, changing the name is awful! It appeared on the C5 and the C6. Why now? Moreover, Z06 name started life on the C2 when 199 Corvettes were made for people who want to race. Why would you ever change a name that heritage in the very direction you want it to be?

        The ls7 v8 is prone to failure as it is.... The new motors are going to based on the new gen, just like the base c7; and more than likely any higher output models will use force induction for the fuel economy advantages over normally aspirated large displacement motors.

        They could even add a hybrid/KERS set up to the ZR-1 to further differentiate it from the Z07 and Sting Ray. With all the chatter from the big wigs in GM about hybrids and Corvette in the future, I wouldn't be surprised if we all saw that in the next ZR-1. Although I don't know where they'd find room to put the system... It might lose some rear cargo room and the extra weight might upset the balance of the C7, however the added weight to the rear might help traction...

          The last thing a corvette needs is extra weight. Actually, the Z06's and the ZR1's killer weapon was weight. They were lighter than the competition which leap in performance.

      I think it's a great idea. Besides, it's not like GM doesn't know turbos. Corvair had them in the 60's. Buick GNX in teh 80's. I'd be happy to make due on the Normally Aspirated Stingray myself.
