Imagining a Midcycle Engine Refresh for the C7 Corvette Stingray

There has been lots of discussion about new engines coming to the Chevrolet Corvette lineup in the form of new, high performance models, but there is an outside possibility that the Stingray could get a new engine before it gets a new look – albeit a long shot. What if the all-aluminum V8 in the GM dealer service system is the new engine for the Chevrolet Corvette Stingray? It isn't likely, but it could happen.

Since the 2014 Chevrolet Corvette Stingray introduced the world to the C7 generation of the fabled American sports car, there has been a ton of speculation about new trimlines and the engines which would power those trimlines. At first, we speculated about the possibility of a new Corvette Z06 or ZR1 and that speculation ended when the C7 Corvette Z06 was introduced with the supercharged LT4 with 650 horsepower and 650lb-ft of torque.

The C7 Corvette Z06 is more like the C6 Corvette ZR1 with its supercharged V8 and premium amenities inside and out, which led to more speculation about a C7 Corvette with even more power – which is presumably set to be called the ZR1. Of course, there are also the long-popular rumors that there is a mid-engine Corvette coming which will also feature a new engine of its own, and each of these rumors touch on the fact that the LT5 name could be reincarnated with the next super-Vette.

Really, it seems that every rumor about any new General Motors V8 directs us to the next high performance Corvette – whether it is called the ZR1, the Zora or some other unique name – because we know that there is a higher performance car coming in the near future. What we don’t ever seem to consider is the possibility that there could be a new, more powerful engine in the Corvette Stingray before the end of the C7 generation.

Is Chevy Planning a 750-hp Camaro Z/28?

Mar 02, 2017 - 2:00 PM - by AutoGuide.com


Everyone was wrong.

For months we’ve watched Chevrolet trot out a pair of Camaro prototypes – both at home and abroad at the vaunted Nürburgring – one with a pedestal wing and one without. Sometimes they whined, other times they didn’t; 'That has to be the Z/28!' we all said.

Instead of doing what we thought, the bow-tie brand did what they wanted, debuting the surprise 2018 Camaro ZL1 1LE just ahead of Daytona 500 festivities last Friday in Florida.

If the ZL1 is already absurd, than the ZL1 1LE is asinine, blurring the lines between what a race car is and what a street car could be.

Mysterious Chevy Camaro Spied Testing for the First Time

Mar 02, 2017 - 8:30 AM - by AutoGuide.com


With multiple layers of camouflage, it’s hard to tell what Chevrolet is up to.

Spy photographers were barely able to catch this Chevy Camaro on camera before it got covered up, but the American automaker is definitely trying to keep something a secret. It may appear at first glance that the Camaro is wearing your typical camouflage outfit, but a closer looks reveals Chevy has tacked on some fake bodywork to the front end to conceal what’s real. As a result, it’s tough to tell which parts are real, and which parts are fake, especially with the extra layer of traditional black-and-white sticker camouflage.

In addition, the hood has a white, translucent material on it that appears to conceal some air outlets on the hood.

Previously, spy photographers caught a more aggressive Camaro being tested and it was believed it would be a hardcore Z/28, but that wasn’t the case, as that prototype turned out to be the Camaro ZL1 1LE that was announced last week. It would make the most sense that this is a prototype for the Z/28 since it is expected late this year or early 2018.

The Camaro isn’t expected to be refreshed until the third quarter of 2019, but there’s a chance Chevrolet has moved up the timing. Or it could be something entirely new, like a hybrid variant. Whatever it is, Chevy is hoping to keep it a secret.

Corvette Sales Down; GM Market Share & ATP Up

Mar 01, 2017 - 8:21 AM - by elegant
Corvette sales for the month of February were down 1.7% compared to one year ago, to 2,081 units, and down 7.5% for the first two months of 2017 compared to 2016.

However, GM overall is doing excellently, gaining significant market share versus competitors based on surging crossover, SUV and pickup sales. And, average purchase prices of new GM units set a February record.

Record sales of crossovers, large SUVs and pickups in February drove General Motors’ (NYSE: GM) retail market share up more than one-half percentage point versus a year ago. Average transaction prices, which reflect what customers pay after sales incentives, also set a February record.

“Our retail-focused go-to-market strategy is delivering robust results,” said Kurt McNeil, U.S. vice president, Sales Operations. “All of our brands grew their average transaction prices by healthy amounts, and we delivered solid growth in the industry’s fastest-growing and most profitable segments.”

February Highlights (vs. February 2016)

GM’s total sales were up 4 percent to 237,388 units compared with an estimated 1 percent decline for the industry. This equates to a market share of 17.5 percent, an increase of 0.9 percentage points.
Retail sales totaled 188,715 units, up 5 percent, compared with a flat industry. This equates to a market share of 17.7 percent, an increase of 0.7 percentage points.
GM’s average transaction prices (ATPs) rose $570 per unit to $34,900, a February record. Three years of J.D. Power PIN data show that GM has led the industry in ATPs in 35 of 36 months through February.
GM internal data shows that incentive spending was essentially flat year over year. This is in sharp contrast to recently published PIN estimates that noted an increase of 2.7 percentage points to 15 percent of ATP.
Commercial deliveries were up 7 percent, driven by an 11 percent increase in pickup sales and a 75 percent increase in Chevrolet Malibu

'18 C7's to Get 10 A & 500 HP

Feb 11, 2017 - 10:10 AM - by elegant
That would be terrific news.

I have learned "Tadgespeak" and Harlanspeak." They honestly answer questions at that moment in time. So when asked twice each earlier whether the 10A would fit into a 2017 C7, they answered "no." They were correct and honest, for like all GM employees, Tadge and Harlan want to keep their jobs by not "commenting of potential product."

I was surprisingly able confirm that around that earlier time the 10A was longer than the A6/A8's when, in the middle of Wyoming last July at a small motel the person we coincidentally parked next to/had dinner with, was the Quality Control Engineer at the transmission plant making 7,500,000, 10A's for GM and Ford, when he said, "the 10A transmission is 2" longer than the A6/A8's."

However, in the March issue of Car and Driver states, referring to the A10 in the 2017 ZL1,

For this to now be true, but not true when Tadge and Harlan said it would not fit would last year, would require the latest A10 case/adjacent parts to have been recently re-designed and made shorter.

If the 2018 C7 thus comes with an A10 which is not only faster, but also more fuel efficient than the A8, then GM could easily up the 2018 StingRay's and GS's 500 HP, maybe even 525, and still maintain the same fuel economy.

Of course this thesis is all conjecture based on Car and Driver either getting someone at GM (or the non-GM transmission plant) to inadvertently speak about the latest version of the A10 or they are plain wrong.

GM reaffirmed positive guidance for the 2017 year though overall, GM's sales this January sales were down 3.8% from January one year ago.

GM estimates that the seasonally adjusted annual selling rate (SAAR) for light vehicles was approximately 17.6 million units.

GM’s ATPs, which reflect retail transaction prices after incentives, rose $1,200 per unit to $34,500, a new January record.

GM was the only domestic automaker and one of only two full-line automakers to reduce incentives as a percentage of ATP. GM spending was 12.7 percent, down 0.3 points, and the industry average was 12.3 percent, up 1.3 points.

Rental deliveries were down 1 percent. Total fleet sales were up 1 percent on a 12 percent increase in Government deliveries and a 1 percent increase in Commercial sales.

GM’s fleet mix was 21 percent of total sales.

Small business deliveries were up 4 percent.
