Putting the ZR1 into perspective. It has 50% more horsepower than the C7.R and also more torque, and around the same top speed. And available for anyone who can pony up the money to buy one.

Ten years ago, maybe even five years ago, did we think this car was even possible for a customer to purchase at under $150K?

Here’s the complete ZR1 article from Motor Trend.

2019 CHEVROLET CORVETTE ZR1 FIRST LOOK: BIG POWER, BIG WING, BIG BET (By Alisa Priddle)

ZR1 name resurfaces on 755-hp Vette coming this spring!

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

Here is one more official GM ZR1 photo that separately surfaced. No live reveal link anywhere yet. We just have the above photos. Guessing that GM will post something live from the Dubai show which starts in two days, but they disappointed us today, so who knows... If anything from that show, it will be posted here.

The ZR1 sure looks a lot calmer in this gray than SO. Might not notice its rear as being different from a Z06 if it instead had the small, not ZTX package wing.

Looking forward to those pictures. Maybe from this Tuesday’s Dubai show?

I just looked more fully at GM’s official media packet that I received an hour ago. There are no pictures of the small wing version in it right now.

Highly, highly unlikely since I was personally told in a chance meeting in Wyoming last summer (2016), by the QC engineer that makes the 10 speed at an independently owned factory, that it can not be shortened and it will not fit in the C7. His statement that it won’t fit has been echoed by Tadge and Harla (before and since).

The leaked GM Order Guide does not show a 10 A either for the SR/GS/Z06.

Very interesting quote from Chief Designer Kirk Bennion about the big ZTX wing and its efficiency.

Kirk Bennion said:
As the highest-performing Corvette ever, the ZR1’s design supports its capability in every way. The new wings, for example, help generate more downforce without adding drag, enhancing road holding and top speed.
That is not blowing smoke, for the extreme drag of the Z07’s rear wickerbill spoilers limited the Z07 to roughly 190 MPH, whereas the new ZR1, albeit with 105 more HP, goes 210+ MPH. And as we all know, when you start getting to around 200 MPH, every MPH faster is exponentially like driving into a wall.

Glad to see that gold/bronze interior trim is limited to the orange package! Could you imagine it in an Admiral Blue car? :nightmare: Also, been doing a little research on the two new paint codes - I'm 99% sure the Shadow Gray is the same as the Graphite Gray Metallic on the Colorado and Silverado trucks. Those have a paint code of WA139X which lines up quite well with the 139X listed in the other thread. Interesting that there are 4 gray tones for '19, that cover the whole range - Ceramic Matrix, Blade Silver, Watkins Glen and Graphite (which is very dark, but not quite as dark a black or Carbon flash).

The 3rd symbol is an outline of 1, in a blue to match the brake calipers.

Well explained. Thanks purpleRac3r.

I am just not in love with the very stylistic ZR1 emblem.

I think I can see that although it would be a fat "1". So the "1" is an outline but the "Z" and "R" are not outlines? Also looks like the down-leg for the "R" is missing. Maybe its art.

Actually on the Sebring Orange Design package, those interior trim pieces are called “bronze” (not just a lighting reflection). That package also includes orange stitching and orange seatbelts. Happy, HAPPY orange lovers.

While a little much for me personally, I could see more than few modding their black interior to “add on” bronze trim pieces.

Here’s great news for ZR1 low wing lovers, especially for you Busa Dave!!! Darn, we are still looking for a picture of it on an un-camo-clad car.

70% greater downforce than a stage 2 Z06 with the ground effect package!

First picture (schematic) of the new front underwing for much better front end downforce with slamming the underside into the pavement.

Lastly, 11 heat exchanges/intercoolers/etc information on the ZR1, e.g., five more than the Z06.
