As much as I love em and have owned a Vette, this new one just does not look like a Vette?..it seems now that cars all sort of look very similar, but I would own it, it would kill me at my age before I killed it at your age!.....

I don't really care for the car, but the engine is very interesting. Chev are going DOHC, high compression (12:1), flat plane crank, intake tricks, tuned headers, over square so high revving etc.
Basically they're going euro style with extra tricks on their own in the valve train. 670HP out of 5.5L (naturally aspirated).
That's more power than the old supercharged 6.2L LT1 in the last model.

Has heaps less torque though - but you'd expect that when no supercharger, smaller engine, less stroke. But yeah, that's the euro way for cars, and they have finally stopped putting a truck motor in a vette LOL.

E: Found this to flesh out the engine as I mentioned because no one else in the links given is talking about how.

The Stingray won’t change, and there’s nothing wrong with that motor either. Both have their place.

It may look good in the USA on a road built for it, but it looks like a track car to me, the Vette always represented a car that an average man could own, but they are built like a Ferrari or McClaren now, but in saying that it's still a Chevy, hopefully built at Bowling Green,
But I love the 1966 Vette, it's shape and styling fitted the 60's.
Big block Tri - power though, the later shape defines Corvette, 68 to 72 I thing the chrome bumpers, oh and L88.

I reckon this model is a decent step backwards over the last one.

In what way?

Sorry.
Definitely meant looks wise.
I don't follow Corvettes enough to know the difference mechanically between the 2.

I agree, to me Corvette is FR but hey the results dont lie. But just looks like another generic sportscar now.

[PooDog]

I'll bet it screams ......see Ford thats how you do it ....oversquare bore change your fuc#ing tooling, we could have had so much more versatility with our vee eights

I love this car, I really do. But it looks nothing like a Corvette so it's a big ****en adjustment

[Mulva]

I actually don't mind the looks. Certainly does not look like a Vette, but does look a lot like the exotics that sell for several $100k's (low-slung wedge-shaped cars that sell for two to three times the cost of the Vette, if not more).

Non-car people would look at it and assume it is a Ferrari...I'm serious when I say that.

[MITCHAY]

It looks really good. But a Corvette is Murica muscle and not a Euro supercar. Well that's the way I have always thought about it.

[oldel]

Yeah. Bare in mind affordable euro v8s are probably going to disappear soon as the mainstream (non supercar) euros automakers go to smaller engines or electric. This corvette is going into probably tapping into that market too.

[kypez]

I'd have been keen if they came in a manual. Yes, slower than the Auto, but I enjoy Manuals; I don't enjoy Autos.

[fgpsi]

that sounds mad. like my vacuum cleaner

call me old fashioned but I reckon the stingray sounds better now especially with aftermarket exhaust

if i had the cash i'd buy a vette for the muscle car sound, not ferarri sounds

Sounds like you have a great sounding vacuum cleaner!

Just as a point of interest, the F1 Race cars between 2006 and 2013 were all oversguare, bore was 2.47 to 1 ratio from memory, then they changed to the poxy sound they make now, yuk, but you get used to it!
The most oversquare engine was a Ducati motor cycle, some ridiculous ratio I think was 1.84 to 1, no ****, forget model.

Yes, generally the shorter the stroke the higher the RPM capacity as there is less piston speed (distance travelled in the bore per stroke) and friction, however this also depends on the breathing efficiency of the heads & intake, AND comes at the cost of compromising Torque.

Too right, but I think we going to get pulled up from straying from the original thread being about the latest Vette, and ending up talking about square and oversquare engines!

But my last word will go to British designer Edward Turner, a motorbike engine designer, who in 1928 designed a 4 cylinder engine and called it the Square Four, he tried to sell the idea to manufacturers and I know BSA knocked him back, as did a few others.

But a company by the name of Ariel took him on, hence the Ariel Square 4, so instead of inline, he put the cylinders in a square configuration, he went on to design the fabulous Triumph Speed Twin engine.

Stopped manufacture in 1959, but in 1971 Austin built a car which used the Ariel Square Four engine in the Austin Healey 100/4 and lasted until 1977.

Just a little bit of trivia!

[Bossxr8]

Windsors didn't rev that hard in stock form because they had such ****y size heads on them. They are atrocious.

Get a good set of alloy heads and a decent cam and it's a whole new ball game. Mine rips between 3000-6500. It's only the stock block holding it back. I'd take it to 7k with a bigger cam if I wasn't concerned about splitting the block.

One day i'll go a dart block and pull the string.

[XRtowcar]

Love the new Corvette and can see the heritage of the model shine through. With the new quad cam engine, it will take the car to another level.
Now let’s get USA pricing in Aus.
