2015 Corvette buyer's guide: the Z06's return, the eight-speed's first year, problems and 2026 prices

Three things were new: the Z06, the eight-speed automatic and the Performance Data Recorder. GM’s 2015 Stingray overview (opens in new tab) lists the rest:

• The recorder, developed with Cosworth: the header camera, a cabin microphone, a 5 Hz GPS and an SD card in the glove box, with Sport, Track or Performance Timing graphics over the video. It came with navigation, on 75.4 percent of 2015s.
• ZF1, an appearance package putting the Z51’s wheels and spoiler on a Stingray without the Z51 hardware.
• The Z51 package now included the performance exhaust, and cost $1,000 more for it.
• Shark Gray and Daytona Sunrise Orange, new black wheel finishes, carbon fiber ground effects (CFZ), suede upper trim on the 3LT and OnStar 4G LTE with a Wi-Fi hotspot.
• The Atlantic and Pacific design packages, the rarest 2015s (see How 2015s were ordered).

RPO is GM’s regular production option code, three characters per option. The LT1, the seven-speed manual and the Z51 hardware carried over from the 2014.

What a 2015 doesn’t have: the front curb-view camera, power-cinching hatch and trunk latches, Apple CarPlay and Magnetic Ride without Z51 all arrived for 2016, and the 2015 owner’s manual has no entry for the cameras, the latches or CarPlay. Owners in one long CorvetteForum thread name the cameras and CarPlay as reasons to buy 2016 or later. On a 2015, Magnetic Ride Control (GM’s adjustable damping) came only with the Z51, as RPO FE4.

From GM’s 2015 spec sheets and releases, the owner’s manual and the EPA. GM’s launch material said 29 mpg highway for the manual Stingray and 23 for the automatic Z06; the EPA’s records say 28 and 21. GM’s Z07 coupe ran the quarter mile in 10.95 seconds with the automatic and 11.2 with the manual, both at 127 mph, and stopped from 60 mph in 99.6 feet. Both cars came with the seven-speed manual or the eight-speed automatic.

Top speed? GM published none for either car in the 2015 material found. The manual’s track settings cap a Z51 at 174 mph and a Z06 at 184, driver only, tires at 26 psi (PDF page 187): tire limits, not top speeds.

Fluids, by the manual. Oil with the filter: 7.0 quarts for a wet-sump LT1, 9.8 for a Z51 or Z06, dexos1 5W-30, with Mobil 1 recommended for the dry sump. Coolant 11.8 quarts, plus 4.5 for the LT4’s intercooler. An 18.6-gallon tank (PDF page 351). The LT1 prefers 91 octane and runs on 87 with less performance; the LT4 needs 91, and below that “damage to the engine may occur and may void the vehicle warranty” (PDF page 235). The battery sits under the cargo floor, as the battery guide shows.

Three in four 2015 Stingrays were automatics, 19,046 of 25,587. On paper the 8L90 was a clear step: more than 8 pounds lighter than the six-speed, a 4.56 first gear against 4.03, a 0.65 eighth, a taller 2.41 axle (2.56 before) and, by GM’s figures, 0–60 mph in 3.7 seconds and 3.5 percent better highway economy.

GM watched it from day one. From July 1, 2014, every 2015 eight-speed replacement went through GM’s Product Quality Center (PQC), first as a “restriction,” then from October 2014 as an exchange program. By October 2015, PIP5200H (opens in new tab) told dealers that “No transmission repairs, internal or external, are allowed” without calling the PQC: a dealer could swap the gearbox through GM but not fix it. The program ended in November 2015. GM did the same for the LT4 engine’s first six months (PIP5225), so this was launch practice, not a defect notice. The bulletins show what it was watching:

• Cracked clutch housings. Update 14628 (September 2014) ordered a drive audit of 2015 automatics still in dealer stock: “A small number of transmissions may develop a crack in the triple clutch housing,” costing reverse and leaving only third and fourth.
• Harsh shifts. Update 14876 reset cars reprogrammed several times at the factory; bulletin 14-07-30-001 relearns shifts on low-mileage cars.
• Engagement from Park. Bulletin 16-NA-014 fixes a delay after the car sits, on Corvette eight-speeds built before October 27, 2015: every 2015.

Then came shudder. The torque converter couples engine to gearbox, and a clutch inside it locks at cruise; on some cars it shudders as it does. GM’s fixes came in three rounds: a new torque converter for 2015–2016 Stingrays shaking between 30 and 65 mph (PIP5337C, March 2016), a triple flush (16-NA-175), then 18-NA-355 (opens in new tab), a one-time exchange to a new Mobil 1 fluid for LT1 and LT4 automatics built before February 1, 2019. That’s every 2015 automatic. There was no recall and no extended coverage.

NHTSA holds 18 complaints against the 2015 eight-speed, all on Stingray VINs. About 10 describe shudder, one at 7,500 miles and one surviving GM’s flush; seven describe harsh or delayed shifts, one after a replacement transmission at 2,000 miles. The 18th is a blog post pasted into the form, so 17 are owners’ own. Not one 2015 Z06 owner filed one, though 4,186 Z06s were automatics. Owners in three CorvetteForum threads from 2016 to 2023 single out the 2015 automatic, and the best Corvette years guide calls it the C7’s hardest look, though most 2015 owners in the 2016 thread report minor fixes or none. So buy the paperwork with the car: the 18-NA-355 receipt and a long light-throttle drive. The generation-wide story is in the C7 guide.

After skipping the C7’s first year, the Z06 was priced at (opens in new tab) $78,995 for the coupe and $83,995 for the convertible, destination included, and began shipping on November 29, 2014, the convertible early in 2015. It was the first Z06 with an automatic, the first with a removable roof panel and the first convertible Z06 since 1963. GM called it the fastest production car it had tested on its Milford Road Course, a second quicker than the C6 ZR1.

The LT4’s 1.7-liter supercharger spins as fast as 20,150 rpm, and GM’s numbers explain the shove: 457 lb-ft just off idle, 625 by 2,800 rpm, 650 hp at the top, 12 more than the C6 ZR1’s LS9. The Z07 package, $7,995, added carbon-ceramic brakes, adjustable aero and Michelin Pilot Sport Cup 2 tires.

Corvette Blogger set the 8,653 against the Z06’s other first years: 199 in 1963, 5,773 in 2001, 6,272 in 2006. Of the 2015s, 6,980 were coupes and 1,673 convertibles, 68.6 percent were 3LZs, 51.6 percent had the manual and nearly 40 percent Z07, as the C7 Z06 guide also says. From March 2015, $5,000 (RPO PBC) let a buyer build their own LT4 at Bowling Green. A white Z06 paced the 2015 Indianapolis 500 with Jeff Gordon driving.

Two Z06 subjects get the full story in the Z06 guide:

• Heat on a hot track. GM’s 2015 target was a manual Z06 lasting a full tank on an 86°F day with a professional driver; the automatic reaches its limits sooner. Every 2015 Z06 was inside Special Coverage N202302720, a radiator update for track overheating, and its 7 years or 72,000 miles have run out on essentially all of them. NHTSA’s three 2015 Z06 overheating complaints include no track session.
• Wheels. 11 of the 2015 Z06’s 19 complaints are cracked wheels, mostly rears, at the inner rim or bead. GM’s wheel reimbursement program for 2015–2019 Z06s closed to claims on January 25, 2025, so a cracked wheel is now the owner’s bill.

From Bowling Green’s 2015 data as Corvette Action Center (opens in new tab) publishes it; shares are this site’s arithmetic.

That’s 8 percent fewer than 2014, from a run that started in August 2014 and ended in mid-June 2015. Among Stingrays, 2LT led (10,625), then 3LT (9,899) and 1LT (5,063). The Z51 went on 52.9 percent, ZF1 on 5,387 cars. Only 6,541 Stingrays had the manual: 2,417 standard-ratio (MEP) and 4,124 close-ratio Z51 gearboxes (MEL).

Colors. Arctic White led (6,461), then Torch Red, Shark Gray and Black; Daytona Sunrise Orange and Night Race Blue tie as the rarest, 1,417 each. Just 133 Z06s got the Twilight Blue interior.

Atlantic and Pacific, the rarest 2015s. GM announced both in April 2014, from two 2013 SEMA show cars; both required a Z51 Stingray in 2LT or 3LT, and Corvette Blogger reported they weren’t built until the end of the year.

• Atlantic (RPO ATI): 17, all convertibles. Any color, Shark Gray vents and rear stinger, chrome Torque wheels, custom luggage.
• Pacific (RPO PFI): 97, all coupes. Five colors, satin black stripes, red-striped satin black wheels, carbon ground effects, a visible carbon roof, red calipers and an indoor cover.

One without ATI or PFI on its option label is a tribute.

Prices, with the $995 destination. The Z06’s come from GM’s release; the Stingray’s from GM’s dealer price schedules as Corvette Blogger reported them, and they rose twice:

So a Stingray coupe started at $53,995 at launch. 2LT added $4,160, 3LT $9,450, the eight-speed $1,725 and Magnetic Ride $1,795.

NHTSA, the US road safety agency, held 65 owner complaints (opens in new tab) against the 2015 on October 23, 2026: 1.9 per 1,000 built, against 1.7 for 2014 and 2.6 for 2016. The engine code in each VIN splits the year in two.

This site’s reading, so approximate; one Stingray complaint has no VIN and is counted by its text. Take away the gearbox and the wheels and 2015 is a quiet year.

The recalls. Three cover build windows in the first weeks, all before Z06 shipping began:

• 14V568000, built August 20 to September 4, 2014 (783 units): only one rear parking brake cable might be seated, so the car could roll on a steep grade.
• 14V570000, built August 20 to 27, 2014 (89 units): the driver air bag’s back plate could fracture and let the bag separate from the wheel.
• 15V031000, built September 26 to October 2, 2014 (43 units): a rear toe link ball joint might not have been tightened.

That’s 89, 783 and 43 cars, but the air bag window sits inside the parking brake window, so the three cover between 826 and 915 cars. The other two, 16V651000 and 17V437000, reflashed the air bag module on 2014–2017 Corvettes. Five recalls, three of them for short 2014 build windows: the same total as the 2014.

Fuel. A small theme on the 2015, against 16 fuel smell or leak complaints for the 2014: three complaints describe a fuel smell, and two more (one car) a gauge sender that let it run dry. GM’s Special Coverage 16009 replaced leaking 2014–2015 left tanks for 5 years or 60,000 miles, now run out. Special Coverage 17469 replaces the fuel pump module on 2014–2017 cars GM lists by VIN whose left tank leaks from a cracked module flange, for 10 years or 120,000 miles from the in-service date: run out on nearly every 2015, though one first sold after October 24, 2016 and under 120,000 miles may still be inside it. A dealer’s VIN check settles it.

The rest of the file:

• Windshields. Six complaints describe stress cracks with no impact.
• The center screen. Three owners describe the screen and backup camera flickering or going blank from a worn display cable.
• Valve springs. Two owners report a broken spring in cylinder 8, and one a failed lifter. Owner statements; GM issued no program. The generation’s AFM lifter story is in the C7 guide.
• GM’s smaller fixes. New software for a false P0731 code that switched off rev matching on Z51 manuals (PIP5260); an OnStar module that could flatten the battery in about four days (program 14395); a steering-gear cooling duct for a “Service Power Steering Gear” message on hot track days (PI1535B, 2014–2018).
• The Valet Mode microphone. If a 2015’s recorder still captures cabin audio in Valet Mode, the dealer update was never done. GM’s quick reference guide shows how Valet Mode is set.

“The eighth character in the VIN is the engine code,” the owner’s manual says, and that character catches a Stingray wearing Z06 badges. The VIN sits at the left front of the dashboard. On a 2015:

• 1G1Y opens every one.
• 5th, the trim: A or B for 1LT, C or D for 2LT, F for 3LT; H for a Z51 1LT, J or K for a Z51 2LT, L or M for a Z51 3LT; N or P for a 1LZ, R or S for a 2LZ, T or U for a 3LZ (all Z06).
• 6th: 2 for a coupe, 3 for a convertible.
• 8th: 7 for the LT1, 6 for the supercharged LT4.
• 10th: F for 2015. 11th: 5 for Bowling Green.

NHTSA’s VIN decoder calls every 2015 a Stingray, Z06 included, so go by the engine code: a 3LZ Z06 coupe starts 1G1YU2D6. The Service Parts Identification Label, under the carpet on the passenger side of the rear storage area, lists every production option. Look for Z51, FE3 or FE4, ZF1, NPP, MEP, MEL or MEK (manuals), M5U (the eight-speed), Z07, and ATI or PFI.

1. Recalls. Run the VIN through NHTSA’s recall lookup (opens in new tab), above all on a car built from August to early October 2014.
2. GM’s history. Ask a Chevrolet dealer for the warranty record: the 17469 list and in-service date, any exchange transmission, any N202302720 radiator on a Z06.
3. An automatic on the road. Cruise at light throttle between 25 and 80 mph and feel for a rumble-strip shudder; check engagement from Park after the car has sat, and for a harsh downshift rolling to a stop.
4. An automatic on paper. The 18-NA-355 receipt. Without it, budget for the exchange; one owner paid $624 in March 2019.
5. A manual. Clean shifts into first and reverse, no clutch chatter, rev matching in every gear.
6. Z06 wheels. All four inspected off the car or on a balancer, inner barrels included.
7. Fuel. Smell around the driver-side rear after a fill above half a tank.
8. Dry-sump oil. On a Z51 or Z06, the manual’s way: warm to at least 175°F, shut off, read five to 10 minutes later. Cold, it can show empty.
9. Break-in on a low-mile car. The manual asks for an oil change after the first 500 miles on a Z51 or Z06 and no track events before 1,500 (PDF page 200). Ask for that receipt.
10. The rest, by a shop that knows C7s: the screen and backup camera through a full warm-up, the windshield, and a pre-purchase inspection on a lift.

From Bring a Trailer’s C7 results (opens in new tab), listings titled “2015 Chevrolet Corvette,” January 1 to October 22, 2026 (this site’s count, from the sold prices Bring a Trailer prints):

The unsold Stingray had a supercharger added, and a Callaway SC757 Z06 at $90,000 is left out as modified. Bring a Trailer leans to low-mile cars: the median mileage among titles that gave one was 8,500, so expect an ordinary car to bring less. Six Stingray sales is a small sample.

Over April to September 2026, the window the C7 Z06 guide uses, nine 2015 Z06s sold at a median $75,000, the figure that guide gives. Over much the same 2026 window, 2014 Stingrays brought $43,000 (21 sales) and 2016 Z06s $78,000 (19 sales): the 2015 is the cheapest Z06 year at auction. No 2015-only Hagerty figure could be read; classic.com’s page for all 2015s, archived December 9, 2024, averaged $64,859 over 126 sales, Stingrays and Z06s together. These are past sales, not a forecast.

Buy the Z06, with the seven-speed manual. It’s the reason 2015 matters, and it’s the cheapest Z06 year at auction: unmodified 2015 Z06s brought a median $76,000 on Bring a Trailer in 2026, and those titled “7-Speed” $79,500, about what a coupe cost new. Bowling Green built 4,467 manual Z06s for 2015, and for long track sessions at professional pace GM’s own advice (PIP5311 (opens in new tab)) was the manual. (An automatic Z06 is a fair street buy: not one 2015 Z06 owner has filed an automatic complaint with NHTSA.) The conditions are every C7 Z06’s: four inspected wheels, since GM’s program has closed, and a straight answer about track days, since the heat coverage has run out. For hard summer track work the Z06 guide points to a 2017–2019 manual; for the road and the occasional track day, a 2015 costs less.

For a Stingray, take a Z51 with the close-ratio manual and the dry sump, and treat the eight-speed as the 2015’s one real question mark. An automatic with the 18-NA-355 receipt and a clean light-throttle drive is fine. Without both, a 2014, whose six-speed sits outside the shudder story, or a 2016, with the cameras and CarPlay, is the smarter Stingray at about the same money. Atlantic and Pacific cars are for the collector; check the label before paying extra.

Pass on a shuddering automatic with no receipts, a Z06 with a tire that keeps losing air, and any car without records. Get past those and the 2015 is the C7’s first Z06, 650 hp of America’s sports car, at the lowest Z06 median of any C7 year. The later years are in the 2017, 2018 and 2019 guides.
