General Motors spent years developing the exhaust note for the C8 Corvette Z06. The result? A cold-start sound that, by one owner's direct comparison, edges out a Lamborghini Huracán LP 610-4. That's a real owner, standing in a real parking garage, listening to two $100,000-plus supercars wake up. And the American car took the round.
The owner in question is Reddit user u/ib1030, who took delivery of a 2023 C8 Z06 exactly one month before posting his review on April 23, 2026. His specification is telling: a 3LZ trim with every carbon fiber option available save the Z07 Performance Package and its towering rear wing. In the past, his garage housed an AMG GTS, a GR Supra, a Mercedes-Benz G63, and a Lexus LX570. When it came time to buy his next toy, he cross-shopped the Z06 against a McLaren 570S and an Audi R8. He chose the Corvette. "The Z06 is the superior car out of the pack," he wrote. After roughly 1,242 miles of mixed highway, city, and mountain-road driving, his enthusiasm hasn't dimmed. "I still get excited every night knowing I get to drive the car the next day." Not every owner agrees; one said the Stingray would have been enough.
The core finding of his one-month test is unambiguous: the exhaust is the best part of the car. u/ib1030 cold-started the Z06 next to a Huracán LP 610-4 and concluded the Z06 "beats it just slightly." Anything above 4,500 RPM in Race or Z Mode produces what he describes as a "very distinct, high-pitch sound" that separates it even from the Ferrari 458 Italia and other naturally aspirated engines. In Comfort mode, the valves close and the car quiets down to daily-driver civility. The only missing ingredient, per the owner, is that true Formula 1 scream as the needle pushes toward redline, the kind of shriek delivered by a Gintani-equipped Lamborghini SVJ or Ferrari 812 Superfast.
The engineering behind that sound is the LT6, a 5.5-liter flat-plane-crank V8. According to GM Authority and duPont REGISTRY, it produces 670 horsepower at 8,400 RPM and 460 lb-ft of torque at 6,300 RPM, with a redline of 8,600 RPM, making it the most powerful naturally aspirated production V8 in the world. The flat-plane crank is the critical differentiator. Unlike the cross-plane crank found in traditional American V8s (including the Stingray's LT2), a flat-plane crank arranges its throws 180 degrees apart. That creates an even firing order, left bank, right bank, left bank, right bank, that eliminates the overlapping exhaust pulses responsible for the classic V8 rumble. The result is a higher-pitched, more sonorous scream. Jalopnik notes that flat-plane designs allow superior exhaust scavenging and quicker revving because the crankshaft carries less mass in counterweights. GM was so committed to getting this right that, according to CarBuzz, engineers sourced a wrecked Ferrari 458 engine from Poland for approximately $25,000 to study the intricacies of a high-revving flat-plane V8.
The LT6 is not a warmed-over small-block. It is a clean-sheet design with dual overhead cams, titanium intake valves, sodium-filled exhaust valves, forged aluminum pistons, forged titanium connecting rods, and a six-stage dry-sump oiling system. The 0-60 MPH sprint takes 2.6 seconds. Top speed is 189 MPH per Chevrolet's official claim, though some independent tests have recorded higher figures.
The visual presence backs up the acoustics. u/ib1030 reports daily waves, filming, and rev requests from strangers on the street. People who don't know cars mistake the Z06 for an Italian exotic. The reason is dimensional. The Z06 is significantly wider than the base Stingray, with dramatically more aggressive aero. Standard aero delivers 365 pounds of downforce at 186 MPH, and the optional Z07 package (not fitted to this car) raises that to 734 pounds via a larger front splitter, dive planes, underbody strakes, and a towering rear wing. The owner describes the Stingray's original design as "too boxy and unnatural," but says the Z06's wider, more aggressive proportions balance out those flaws. It looks the part. And in an era when the Audi R8 is being retired, and the McLaren 570S has ended production, the Z06's design language feels freshly relevant.
Fairness demands acknowledging the other side. Plenty of C8 coupe owners adore the targa top. The manually removable roof panel offers an open-air experience without the weight penalty or structural complexity of a full convertible. CorvetteForum data shows that, despite a roughly $7,000 premium for the Hardtop Convertible (HTC) in 2023, sales split almost evenly: 51 percent coupe, 49 percent HTC. Some buyers specifically want the Targa's coupe silhouette with occasional alfresco capability. As for the handling, u/ib1030 calls it "almost too refined" and notes that sliding is "non-existent," which robs some fun factor. Many drivers, particularly those who drive their cars in rain or near-freezing temperatures, would call that a feature. The owner notes he has been running on "cold-cool" Michelin Pilot Sport 4S tires. That phrasing most likely refers to tires that had not yet reached operating temperature, a common condition after short drives or cold starts, rather than a commentary on cold-weather capability. The PS4S is a Max Performance Summer tire, and like any summer compound, it delivers peak grip only after warming through driving. The Z06's planted behavior, even on cool rubber, speaks to the chassis balance and mid-engine weight distribution.
The practical compromises are real. Both the trunk and frunk get "very hot" even without pushing the car hard, according to u/ib1030, who warns against storing fragile or refrigerated items in either compartment. The cause is the mid-engine layout. The LT6 sits directly behind the cabin, and the exhaust routing passes beneath and alongside both storage compartments. Heat soak is a known characteristic of mid-engine cars; the Ferrari 458 and Lamborghini Huracán suffer similar issues. CorvetteForum threads confirm other owners have noticed elevated temperatures in the C8's storage areas after spirited drives. Then there is the targa top itself. The owner calls it "a bit of a gimmick." It is easy enough to remove, but the process kills the spontaneity of a true convertible. He took the roof off once a month and never bothered again. His recommendation is unambiguous: "I would strongly recommend going for the HTC version." A rented C8 targa top previously flew off on the highway, showing the removable panel's risks. Pricing context supports that advice. GM Authority lists the 2023 Z06 1LZ Coupe at $106,395 and the 1LZ Convertible at $113,895, a $7,500 difference. For 2026, Chevrolet lists the Z06 Coupe 1LZ at $120,195 and the Convertible 1LZ at $127,195. For buyers already spending six figures, the premium buys a power-retractable hardtop that operates at speeds up to 30 MPH and transforms the car into a genuine open-air exotic.
Independent validation backs up the owner's enthusiasm. In its instrumented test of the 2023 Z06, Car and Driver delivered a verdict that echoes across every paragraph of this review: "The exhaust note is an insistent presence that fills the car with nervous energy just cruising around town. Ferraris and Lamborghinis do that too, and the Z06 sounds like them but also like its own thing." The magazine praised the multimode exhaust system's range, from near-silent Stealth mode to a "brain-scrambling scream" essentially equivalent to straight pipes.
Car and Driver also noted that the Z06 is "an intoxicating thriller on the street and an iron-fisted killer on the track," with ride quality that remains compliant enough for daily use. The publication's testers settled on a custom MyMode configuration: softest ride, Sport-level steering and brake feel, and Track-mode exhaust. They turned the exhaust down only when it "wore our ears out." That is the duality the owner describes. A car that can intimidate a Huracán at 6:00 AM and commute in silence at 8:00 AM.
If open-air driving matters, skip the targa and order the HTC. The power-operated hardtop eliminates the friction that makes the removable panel a garage-bound novelty. If cargo heat is a concern, plan accordingly: soft coolers won't survive a mountain pass, and chocolate is a bad idea regardless of season. The real value proposition, however, remains the powertrain. At a starting price around $112,000-$114,000, the Z06 undercuts the Huracán LP 610-4 (which started at roughly $237,000 when new and commands $170,000-plus used) by more than half. It matches or beats the Lamborghini to 60 MPH. And in the owner's direct comparison, it wins the sound contest. Aftermarket exhaust brands are already capitalizing on the LT6's potential. Avior Performance and AeroFlowDynamics both offer valved titanium systems designed to push the flat-plane pitch closer to the Formula 1 scream the owner described. u/ib1030 is waiting for his warranty to expire before modifying. A 2025 shopper called the Z06 a beautiful wide-body beast. Most owners should probably do the same. Another owner compared the Z06 to Lamborghini and Ferrari and reached a similar verdict.
One month and 1,242 miles into ownership, the verdict is in. The Z06 intimidates a Huracán at 6:00 AM, commutes in silence at 8:00 AM, and costs half what the Italian car commands. The targa top collects dust in the garage. The trunk runs hot enough to melt chocolate. And none of it matters, because every night, the owner still gets excited about driving it the next day. Some cars justify their price tag with spec sheets. This one earns it with a sound that beats a Lamborghini cold-start and a presence that strangers mistake for an exotic.
