LOS ANGELES November 28th 2017 — Chevrolet today dropped the top on the 2019 Corvette ZR1 with the global introduction of the ZR1 convertible, the first ZR1 drop-top since the original 1970 model-year ZR1.

On sale next spring alongside the Corvette ZR1 coupe, the ZR1 convertible emphasizes Corvette’s iconic proportions and functional sculpture, highlighting the seamless transition between the exterior and interior.

The ZR1 coupe will carry a suggested retail price of $119,995, while the ZR1 convertible will start at $123,995 (prices include destination charge, but exclude tax, title and other dealer fees).

“The new Corvette ZR1 convertible is a supercar in all respects,” said Mark Reuss, executive vice president, Global Product Development, Purchasing and Supply Chain. “Few others can challenge the ZR1 convertible’s power and speed while offering the exhilaration of top-down motoring.”

The performance and technology introduced on the Corvette ZR1 coupe carry over to the new ZR1 convertible. The strength of the Corvette’s aluminum chassis means the only structural changes in the convertible are accommodations for the folding top and repositioned safety belt mounts. The power top can be operated remotely or while driving up to 30 mph.

In fact, the curb weight difference between the ZR1 coupe and convertible is less than 60 pounds (27 kg), with most of the difference attributed to the folding top hardware.

“The ZR1 convertible is a no-compromise supercar,” said Corvette Executive Chief Engineer Tadge Juechter. “Thanks to the strong structure, the suspension tuning between coupe and convertible models is identical, meaning the ZR1 convertible offers the same benchmark performance, including a top speed of over 200 mph.”

The Corvette ZR1’s unique aero package is central to the coupe’s 212-mph (341 kph) top speed. Its standard, stanchion-mounted Low Wing generates road-holding downforce with minimal drag, enabling the benchmark top speed. This was evident during top-speed testing at Germany’s Papenburg proving ground.

An adjustable High Wing is part of the new $2,995 ZTK Performance Package, which also includes a front splitter with carbon-fiber end caps, Michelin Pilot Sport Cup 2 tires and specific chassis and Magnetic Ride Control tuning. It is designed to help generate faster lap times through maximum grip in the corners, with up to 950 pounds of downforce. The top speed is lower with the High Wing but still exceeds 200 mph.

Complementing the ZR1’s aero advantage on the way to 212 mph is the thrust generated by the exclusive LT5 6.2L supercharged engine, which is rated at an SAE-certified 755 horsepower (563 kW) and 715 lb-ft of torque (969 Nm). A seven-speed manual transmission and a ZR1-first paddle-shift eight-speed automatic transmission are offered with it. Preliminary testing has shown 0-60 mph in under 3.0 seconds and the quarter mile in the high 10-second range when the engine is equipped with the eight-speed automatic.

The LT5 features a new, more efficient intercooled supercharger system, along with GM’s first dual fuel-injection system, which employs primary direct injection and supplemental port injection. Compared to the supercharger system on the Corvette Z06’s LT4 engine, the LT5 employs a larger, 2.65-liter supercharger that generates more boost while spinning at a slightly slower speed. That reduces heat to help maintain a lower air intake temperature for optimal performance.

Four new radiators also help manage cooling in the ZR1, which features 13 radiators in all, including circuits for engine oil, transmission and differential cooling.

A new, patent-pending exhaust system is the voice of the supercharged LT5 engine and offers the most aggressive sound ever for a production Corvette.
Building on the bi-modal exhaust system offered on other Corvette models, it features four distinct modes and sound levels: Stealth, Tour, Sport and Track. In Stealth mode, the ZR1 is quieter than the Corvette Z06, while in Track mode it is significantly louder.
In Track mode, a spring-loaded passive valve closes to allow virtually unrestricted exhaust flow for maximum performance. The exhaust note for all modes was carefully tuned to deliver a distinctive sound.

Corvette C7 755 hp ZR1 Coupe 2019

DETROIT, MICHIGAN November 12th 2017 - 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.
