I know, zombie quote. But practical displacements on the LS blocks are about 468ci (7.66L) on a stock deck height block and 524ci (8.6L) on a tall deck block.

Those are the LS based motors we use in competition cars.

When we think of a car being wrecked so badly that it’s effectively totaled, we tend to imagine pretty gruesome, mangled wrecks. What we don’t usually picture is an incident that left damage so small you could hide it with your thumb, but that’s exactly what happened to one deeply unlucky Corvette.

The incident—it’s too minor to really be called a wreck—happened late last month, as a 2017 Corvette Grand Sport owner who goes by cdm85-251 on CorvetteForum. I reached out to the ‘Vette’s owner, and here’s how he described what happened:

On July 19, my wife and I were in the middle of northbound late in heavy traffic heading back from Des Moines on I-35 by Ankeny, IA. The vehicle in front of us had cleared an object that was lying in the middle of my lane. I couldn’t avoid it or stop without causing what would probably be serious accidents for multiple vehicles. I had no choice other than to go over it, hoping it was small enough to go under the car.

We aren’t sure what it was, maybe a rock, maybe a chunk of steel, but whatever it was, it was HARD. It barely nicked one of the alignment adjustment cams, then went on to dent the aluminum stiffening panel that also protects the exhaust and torque tube, bending three bolts on the panel and broke the head off one. Further back it dented a shield for the driver’s side gas tank and then hit a part of the frame. At least it missed the oil cooler.

I had it inspected at Karl Chevrolet the next day and from a quick look, there didn’t seem to be any serious damage. We took it in to Karl’s for repair a few weeks later and we were told the frame strike caused a small crack, less than an inch and a half long and they were having difficulty finding a replacement part.

A few days later, the shop told us the part is not available from Chevrolet and the car would be totaled.

That led to a week and a half of calls with the insurance company who disputed what we were told as they thought that a part may be available or that the crack could be welded. We couldn’t get them to answer our question about who would warranty the car when welding apart that was labeled as unavailable from Chevrolet. Chevrolet indicated replacing it would compromise the structural integrity of the car.

The insurance company finally came to the same conclusion on the frame part being unavailable, and declared it a total loss. We were surprised that after all of this, they gave us a fair offer and had a check to us for the car the very next day.
So, to sum up, guy’s driving his Corvette on the highway, runs over some debris in the road, and thanks to the fate and her miserable, cruel sense of humor, that hard lump of whatever in the road managed to hit, with almost surgical precision, one of the points of the car’s underbelly that, if damaged, effectively compromises the car’s entire frame and is essentially impossible to fix, at least while keeping the car’s warranty.


The actual damage consisted of a crack, a bit over an inch long, on the part of the frame known as the rear transmission tunnel.

Here’s what the car-totaling crack looks like:



...and here’s the approximate location under the car:



It seems insane that one little crack like that could compromise an entire car, but car frames are under a great deal of stress, and assessing damage like this isn’t always intuitive.

Then again, this all seems sort of insane if you think about how many cars on the road in the Northeast and Midwest have frames made of the finest, flakiest rust that water and road salt can provide.

While it certainly seems like the frame could be welded and repaired by a skilled aluminum welder, even if the repair is perfect, Chevrolet will refuse to warranty the car, according to the owner, who investigated repair solutions.

I also can’t help but wonder what would have happened if the tiny crack wasn’t found at all? It’s not clear if this little crack would have caused any sort of catastrophic failure or not; I’m not sure anyone can say for sure.

The good news is the insurance company provided a fair settlement, and the owner was able to replace the car with a 2018 Corvette Grand Sport that looks pretty damn close to the ‘totaled’ car:



For those of you convinced you can repair the car and put it back on the road, here’s your chance. The car is up for auction, and the auction site lists the repair costs at about $7600.



So, if you’re not a stickler for warranties, have the ability to weld aluminum or have the ability to forget about potential problems, this ‘Vette could be a sweet deal for you!

[vh_supra26]

It’s official. After spy shots, speculation, and leaks, the 2019 Chevrolet Corvette ZR1 formally breaks cover here in Dubai, home of the fast, rich, and fabulous.

Yes, this latest iteration shares much of the bones of the Z06 but adds more power, refinement, a giant optional rear wing, and a pledge that this really fast car is for everyone. Even though the new ZR1 has a top speed of more than 210 mph, the Z06 and Camaro ZL1 1LE still corner the market on crazy.

General Motors chose Dubai for the global premiere of the last celebration of the C7 generation Corvette and the return of the ZR1 crown that was applied to the third-generation Corvette in 1979, C4 in 1990, and C6 in 2009. “We don’t do a ZR1 every generation,” said chief engineer Tadge Juechter. “It’s not an automatic.”

The private unveiling was held a few days before the Dubai auto show. Corvette continues to grow in popularity in the fast-growing Middle East, making Dubai a good choice for the global debut, said Tom Peters, director of exterior design for GM performance vehicles.

The car goes on sale this spring, and GM expects to make 2,000-3,000 of them at the plant in Bowling Green, Kentucky, but production will not be limited.

Pricing has not been announced but could easily exceed $130,000. The 2009 ZR1 started at $105,000; a carbon fiber package alone added $15,000. The 2018 base Stingray coupe starts at $56,490 and the Z06 starts at $80,490. Juechter said the ZR1 won’t be double the price of the Stingray.

Many of the suspected details were confirmed. The new coupe continues with GM’s 6.2-liter pushrod small block V-8, but the automaker calls this updated version of the supercharged engine the LT5. It’s confusing because the expectation is LT5 would refer to a switch to a DOHC V-8. The ZR1 sticks with Corvette’s traditional overhead valve, two valves per cylinder.

And just when you thought that engine couldn’t squeeze out any more power, GM tells us it’s rated at 755 horsepower and 715 lb-ft of torque. “After driving this around for a while the Z06 feels really sluggish,” said Juechter. It’s a nice exclamation point in the dying embers of C7 before C8 goes mid-engine and DOHC.

“I’ve never driven a Corvette like this before, and nobody else has either, because there’s never been one like this before,” said Mark Reuss, executive vice president, Global Product Development, Purchasing and Supply Chain. “Its unprecedented performance puts all other global supercars on notice that the ZR1 is back.”

A major difference: This is not the supercharger of the 2009 ZR1 or the 2015 Z06. The Eaton supercharger is 2.9 inches taller with a more efficient intercooled system that Chevy says has 52 percent more displacement than the Z06’s LT4 supercharger. Cooling has always been a Corvette bugaboo. The heavier supercharger changed the weight distribution so Chevy made the front wheels a half-inch wider for more cornering stiffness.

Another big difference: GM’s first dual fuel-injection system. It has primary direct injection and supplemental port injection. A cool by-product: It is said to shoot flames from the exhaust.

The Corvette keeps the seven-speed manual, but buyers can also choose an automatic for the first time in a ZR1 with GM’s eight-speed with paddle-shift. There was speculation the model could receive GM’s new 10-speed co-developed with Ford, but Juechter said that unit doesn’t fit the Corvette architecture and was never designed to. Instead, they updated the eight-speed to shift faster.

The ZR1 has the carbon ceramic brakes of the Z06—not the stellar non-ceramic Brembo brakes in the Camaro ZL1 1LE that are among the best on the planet, as we discovered in Motor Trend’s Best Driver’s Car testing.

The look of the most powerful Corvette to date reveals the efforts Chevy has gone to for greater performance. The strip of carbon fiber down the middle of the hood is the cover for the bulging engine that Peters did not want to be any taller so the driver can still sit low in the seat and see over the hood. It was a craftsmanship challenge to match the weave of the many pieces of carbon fiber that had to come together.

The front clip is all new and the new front fascia has four new radiators which means 13 heat exchangers in total. “The front end has almost no fascia; it is almost all openings,” Juechter said.

And the crankshaft has been strengthened. These changes, and the larger supercharger, add about 60 pounds of weight to the car. Curb weight is 3,560 pounds for a car with the most carbon fiber to date.

The latest king is designed to perform better on the track with the option to forego the regular low wing for a crazy high wing that produces an estimated 950 pounds of downforce for the track. The adjustable high wing is part of the ZTK Performance package and is attached right to the chassis. It can be adjusted about five degrees but it’s not an automatic adjustment; it requires changing the bolts. Even the low wing generates up to 70 percent more downforce than the Z06’s base aero package, and it’s much easier to get at your gear in the back.

This is the first Vette to get a front underwing to assist with downforce. Historically GM would use front splitters to push the nose down, but balancing the big wing would result in a front that too easily scrapes the ground. Borrowing some race tech, incorporating underwing creates low pressure to keep the car down, said Peters.

The ZTK package includes a front splitter with carbon-fiber end caps, Michelin Pilot Sport Cup 2 summer-only tires, and tuning of the chassis and Magnetic Ride Control for better cornering grip—another area where Corvette needed improvement.

And if you like orange, the Sebring Orange Design package is, you guessed it, Sebring Orange with matching brake calipers, rocker and splitter accent stripes, seatbelts, stitching, and bronze aluminum interior trim. There was a strong customer pull for orange, Juechter said. “We’ll see if they show up with their money.”

The ZR1 has leather-trimmed seats with a suede-like microfiber and an option to make them heated and cooled. Or you can opt for a sport seats and a carbon-fiber rimmed steering wheel.

Based on all the spy shots out there, the new coupe with a removable hardtop will be quickly followed by a convertible ZR1 with a soft top.

We doubt it’s a top priority, but the estimated fuel economy is 15/22 mpg in city/highway driving with the manual and 13/23 mpg with the automatic.

GM has been getting ready for the 2019 ZR1 as well as the mid-engine Corvette in the works. Production of the 2018 model at the plant in Bowling Green, Kentucky, stopped for three months to retool for future products.

The 2019 Corvette ZR1 will be on display later this month at the Los Angeles auto show.

2019 CORVETTE ZR1: RETURN OF THE KING
The fastest, most powerful production Corvette ever retakes its supercar crown
2017-11-12

DUBAI — The King is returning, stronger than ever.

Chevrolet today introduced the 2019 Corvette ZR1, a supercar that pushes Corvette’s performance legacy with the highest power, greatest track performance and most advanced technology in its production history.

“I’ve never driven a Corvette like this before, and nobody else has either, because there’s never been one like this before,” said Mark Reuss, executive vice president, Global Product Development, Purchasing and Supply Chain. “Its unprecedented performance puts all other global supercars on notice that the ZR1 is back.”

The Corvette ZR1’s exclusive LT5 supercharged engine, which is rated at an SAE-certified 755 horsepower (563 kW) and 715 lb-ft of torque (969 Nm), is establishing a new benchmark in performance. Further, the ZR1 elevates Corvette’s track capability with two wind tunnel-honed aerodynamics packages, including an available High Wing that provides an estimated 950 pounds of downforce.

Most powerful ever

The ZR1’s LT5 6.2L V-8 engine advances Corvette’s supercharging legacy, which began with the 2009 sixth-generation ZR1 and continued with the 2015 seventh-generation Z06. The LT5 delivers the highest output ever for a Chevrolet production vehicle, thanks in part to a new, more-efficient intercooled supercharger system that offers 52 percent more displacement than the Z06’s LT4 supercharger. GM’s first dual-fuel-injection system, which employs primary direct injection and supplemental port injection, helps the LT5 achieve its record output.

Seven-speed manual and eight-speed paddle-shift automatic transmissions are available with the LT5. It’s the first time an automatic transmission has been offered in a ZR1.

Fastest ever

The 2019 Corvette ZR1’s aggressive appearance is driven by function, contributing to its distinction as the fastest production Corvette to date.

An all-new front fascia is designed to channel air for propulsion-system and drivetrain cooling, with four new radiators bringing the heat-exchanger total to 13. A special carbon-fiber “halo” hood is open in the middle to clear the LT5 engine’s supercharger/intercooler assembly. Additional features, including aero packages with stanchion-mounted wings, help push the ZR1 harder onto the track for more confident handling and faster lap times. Top speed of the ZR1 is over 210 mph.

“As the highest-performing Corvette ever, the ZR1’s design supports its capability in every way,” said Kirk Bennion, Exterior Design manager. “The new wings, for example, help generate more downforce without adding drag, enhancing road holding and top speed.”

The ZR1 will offer two aero packages: a standard rear Low Wing, which delivers the highest top speed and helps generate up to 70 percent more downforce than the Z06’s base aero package, and an available two-way-adjustable High Wing that offers maximum downforce on the track for the quickest lap times — about 60 percent more downforce than the Z06 with the available Z07 Performance Package. All models also feature a Chevrolet-first, downforce-enhancing front underwing.

The adjustable High Wing is part of the new ZTK Performance Package, which also includes a front splitter with carbon-fiber end caps, Michelin Pilot Sport Cup 2 summer-only tires, and specific chassis and Magnetic Ride Control tuning for greater cornering grip.

Both of the ZR1’s wings are tied into the chassis, like the Corvette Racing C7.R racecar, for strength and stability.

Sebring Orange Design Package

The Corvette ZR1 introduced today also debuted a dynamic, available Sebring Orange Design Package. Centered on its Sebring Orange Tintcoat exterior color, the package also includes orange brake calipers, orange rocker and splitter accent stripes, orange seat belts, orange interior stitching and unique, bronze aluminum interior trim.

The new design package complements the Corvette ZR1’s tradition of offering maximum performance with refinement and design distinction. The driver-focused, well-appointed cockpit includes standard leather-trimmed seats, with sueded microfiber inserts offered. Heated and vented Napa leather-trimmed seating is also available, as well as a carbon fiber-rimmed steering wheel, competition sport seats, Performance Data Recorder, Bose premium audio system and more.

The 2019 Corvette ZR1 goes on sale next spring, poised to take on the world’s best.

It’s good to be the King.
