Chevrolet Corvette ZR1: Here It Is, In All its 755-HP Glory

Chevrolet Corvette ZR1: Here It Is, In All its 755-HP Glory

The King of the Hill is back.

Update, 11/29/2017 : Chevy has just officially unveiled the 2019 Corvette ZR1 Convertible at the 2017 Los Angeles Auto Show. Find specs, price and photos right here.

The pack leader is finally here, launched in Sebring Orange to make sure you notice all the significant upgrades that no doubt make it the fastest street car GM has ever made. This is the 2019 Chevrolet Corvette ZR1.

Not all Corvette generations spawn a ZR1, but the previous one from 2009 left quite an impression with its 638 horsepower LS9. Eight years wiser, the Corvette team used all they had to create a worthy successor. Looking at all the figures, the C7 ZR1 shouldn’t disappoint.

It all start with its big, bulging exposed carbon-fiber hood. Apparently, GM put a lot of effort into coming up with the C6 ZR1’s transparent hood window, only to find that some customers thought it looked like a cheap piece of plastic. So this time around, they went all in.

The trick is that one of those two pieces is the actual carbon fiber intercooler cover, meaning that the engine is out in the open through what GM calls a “halo” hood. The carbon weave is perfectly aligned with the body panel, but the intercooler cover will move around when the engine is running, since it’s part of the drivetrain. Now that’s just bonkers.

What’s more, the two openings in front of the cover extrude hot air from the engine bay, which is much needed, since the ZR1 packs eight very angry cylinders.

Despite all the wishful thinking, the new LT5 doesn’t come with a DOHC head like the Lotus-enhanced original did in the ’90s. Instead, the ZR1’s new pushrod V8 features a 52-percent larger supercharger than the Z06’s LT4, as well as GM’s first dual-injection system, to get 755 horsepower and 715 lb-ft of torque out of high octane and dense air.

This dry sump motor also features GM’s largest ever throttle bodies at 95mm, as well as an upgraded crankshaft with a wider key slot. What’s even cooler is that the whole thing is connected to a patent-pending active exhaust, which should give you a wider range of nasty noises, promising Motörhead-levels of decibels in race mode. And since they don’t expect to sell more than 3000 ZR1s a year, all of the LT5s will be hand-built in Bowling Green

To keep all that power on the asphalt, Chevrolet came up with an equally serious aero package in a rolling wind tunnel, with both versions of the ZR1’s available rear wings bolted to the chassis itself—not unlike the Corvette Racing C7.R.

Chevy claims that after benchmarking a few sports cars with active wings, they came to the conclusion that those serve more of an aesthetic purpose than anything else. That, and the fact that an active wing would have been a packaging nightmare on the C7, led Chevy to offer a pair of fixed wing designs, as well as a clever front underwing designed to balance out the additional rear downforce without making the car unusable on the street. It gives the ZR1 an estimated 950 lbs. of downforce near its top speed.

Said top speed is “somewhere above” 210 miles per hour, as long as you stick to the standard wing.

Talking of sticks, there’s an available seven-speed manual with rev-matching that’s “more robust for track duty,” but for the first time ever, the ZR1 can also be had with GM’s 8-speed automatic. The 10-speed auto simply didn’t fit, as it was never intended for the C7 platform.

If you must know, the final drive ratios are 3.42 (manual) and 2.41 (automatic).

Dual-injection means the LT5 uses primary direct injection as well as supplemental port injection, to get 755 horsepower out of 6.2 liters with the help of that gigantic supercharger. And those “conservatively estimated” 755 horses have to motivate 3560 lbs. of Corvette.

Huge forces demand lots of rubber, so the ZR1 comes with 335 section rear tires, as well as half an inch wider front wheels with an open design for improved brake cooling. The brakes are equally monstrous two-piece carbon ceramic rotors, with fixed six-piston aluminum calipers at the front.

Remember the Z06’s overheating issues? GM does too.
