2019 CORVETTE ZR1: RETURN OF THE KINGThe fastest, most powerful production Corvette ever retakes its supercar crown

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.

It has enough power to weight ratio to accelerate from 0-60 under 2.8s
providing there's enough grip. (That will be a real challenge)

And it could do so without shiftting out of first gear if the gearing was tall enough. Which I doubt, but hopefully the auto is quick enough not to loose too much time between gears.

Just some small additions

-2019 C7 ZR1

-LT5 6.2L GEN V SBC V-8

-755hp @ 6300rpm/715lb/ft torque @4400rpm torque

-3560lbs.

-210mph top speed

-2.5-2.8 seconds 0-60, mid 10's in the 1/4 mile(st.)

-2.65-liter Eaton supercharger for LT5 featuring 13 psi of boost, (was 1.7 liter Eaton for the LT4-9.4psi that comes on 1500rpm earlier than the LS9. The LS9 used a 2.3 liter Eaton Roots style blower that made 9.7psi

(GM says the LT5 blower is 52% larger than the LT4s blower, but that's not what I get(64%)- can someone check that for me?)

-13 heat exchangers in total(4 new ones have been added for ZR1)

-2000-3000 per year production

-4th iteration Corvette to wear the ZR1 badge

-7 speed manual/8 speed paddle shifted auto available (1st time an auto available in a ZR1)

-new 4" 102mm throttle-body, largest used on any Corvette

-GM’s first dual-fuel-injection system, which employs primary direct injection and supplemental port injection (at least there is something in common with the 1990-1995 LT5- with its 16 fuel injectors)

-P285/30ZR19 front P335/25ZR20 rear

-$130,000 base price(est.)

Cmon guys is the new Eaton blower for the LT5 at 2.65 liters of displacement, 52% larger than the GEN 5 SBC LT4 with its Eaton blower that displaces 1.7 liters?

Is that a simple 1700cc/2650cc= formula?

I keep getting 62%

52% larger that 1700cc gives me 2584cc

I'm seeing 13 psi of boost as well, that's a decent pressure esp. when you add in the fact that this new boosted LT5 features 11.7:1 compression.

I question that 11.7:1 report, as IIRC the Direct Injection LT4 with 9.7 psi of boost got only 10.1:1 compression

i question this as well - that would be some crazy cylinder pressure, and i dont think it would run on 92/93 pump gas - unless they are tuning very fat.....

i think it may be a typo....

The main advantage of direct injection is detonation can be avoided completely. High octane and fat fueling is needed to counter the fuel igniting early due to heat and pressure. When you aren't injecting the fuel until TDC, detonation is no longer a problem. I can see a next generation fuel injection system being able to reliably handle 15 to 1 compression on 85 octane on an 18 to 1 fuel/air mix. It will just require improvements to the injectors and computer system, and perhaps cooling passage improvements and I wouldn't be a bit surprised if they weren't already testing such systems now. They'd be able to pull 45MPG or better out of a Corvette, while building 800HP or more, with such a setup. Full size trucks would likely be seeing 30-35MPG at cruise unloaded while being able to pull 10,000lbs. These are guesses, mind you.

i read that they are running dual injectors - the DI setup, as well as traditional wet injectors - which im guessing come on under boost....

2 possible new GEN 6 SBC engines for C8 Corvette mid engine RWD Corvette

650hp 4.2 liter/256 cid twin turbo DOHC

or

850hp 5.5 liter/336cid twin turbo DOHC


The GEN 5 6.2 liter supercharged LT5 V8 for the just announced 2019 ZR-1 will be around through 2021.

Apparently there is a possibility the new mid-engine C8 Vettes may be sold alongside the standard C7 and C7 ZR-1 Corvettes. There also may be a split Cadillac/Chevrolet vehicle like the Cadillac 320hp Northstar 4.6l XLR and 443hp s/c 4.4l Northstar XLR-V and Chev C6 Corvette cars that were built at Bowling Green Kentucky from 2004-2009.

2018 Corvette production has been truncated to just 9700 units consisting of the 650hp/650lb/ft s/c LT4 engine and the base C7 with its 455/460hp GEN 5 LT1 SBC.
