2001 Corvette buyer's guide: the first Z06, the 350 hp LS1, the column lock change and 2026 prices

The headline was 5 hp, from 345 to 350. The real gain was lower down: GM’s kit puts 300 lb-ft on tap at 1,000 rpm, 400 rpm sooner than before, and 340 lb-ft at 2,500 rpm, 1,400 rpm sooner. Peak torque rose to 375 lb-ft on manual cars and 360 on automatics, against 350 for both in 2000. The LS1 got the LS6’s new intake manifold and thin-wall cast iron exhaust manifolds to do it.

GM’s 2001 overview (opens in new tab) aimed most of that at the automatic: a quarter second quicker to 60 mph than in 2000 with the standard axle, and as quick as the 2000 six-speed with the 3.15 axle. The drivetrain got stronger at the same time:

• Driveshaft. A 63 mm aluminum shaft replaced the 55 mm composite one, with stronger couplings on manual cars.
• Clutch. More clamping force and less pedal effort on every six-speed, plus carbon blocker rings in the synchronizers (kit, PDF page 16).
• Active Handling. GM’s stability control became standard, in a second generation with a lighter Bosch modulator and a Competitive mode that can be selected on the move.
• Refinement. An alternator clutch pulley for a lower automatic idle, better sound insulation, a new convertible top, chrome-flashed exhaust tips and a slimmer key fob (kit, PDF page 12).
• Battery and oil. An Absorbent Glass Mat (AGM) battery on the coupe and convertible, and the oil change interval stretched from 10,000 to 15,000 miles or a year.
• Paint. Speedway White replaced Arctic White, and Quicksilver replaced Sebring Silver.

The gearbox ratios, the body, the 18.5-gallon tank and the run-flat tires with their pressure monitor carried over. The hardtop didn’t: for 2001 its body became the Z06, so the 2000 was its last year.

GM’s kit lists what turned an LS1 into an LS6: a block with windows between the cylinder bays for crankcase breathing, stronger pistons, 10.5:1 compression against 10.1, a higher-lift cam, stiffer valve springs, bigger injectors and a crankcase ventilation (PCV) system moved into the valley cover, with baffles to separate oil. The result was 385 hp at 6,000 rpm and 385 lb-ft at 4,800, with a 6,500 rpm redline. No other 2001 Corvette got it.

Behind it sat the M12, a Z06-only six-speed with shorter gears (first is 2.97 against the regular six-speed’s 2.66) and a 3.42 axle. Under it, the FE4 suspension, with a larger front anti-roll bar, a stiffer rear leaf spring and revised camber, on forged wheels painted light gray, an inch wider than the coupe’s at each end, and Goodyear Eagle F1 Supercar tires. From ahead of the rear axle back, the exhaust was titanium, muffler and tips included: 17.6 lb lighter than the stainless system and, in GM’s words, “the first-ever use of this exotic metal in a mass-production automobile” (kit, PDF page 17). Thinner glass and a smaller battery took out more weight. Red calipers, a red engine cover and rear brake cooling scoops mark one.

GM’s feature chart leaves plenty off the Z06: the automatic, the head-up display, fog lamps, Twilight Sentinel, the CD changer and the tire pressure monitor. Its tires aren’t run-flats, so an inflator kit rides along (owner’s manual), and its roof stays on. It came in five colors, with black leather or black with Torch Red accents.

GM’s weights disagree with each other. The kit’s product text puts the Z06 117 lb under a coupe or convertible; its specification table gives 3,130 lb for the Z06, a manual, and 3,212 lb for an automatic coupe, 82 lb apart (specifications, PDF page 23). The table’s weights are estimates, and no GM weight for a 2001 manual coupe turned up. GM’s first-edition owner’s manual disagrees on power too, printing the LS6 at 380 hp and 380 lb-ft against the kit’s and releases’ 385 and 385. This page goes with the kit.

For 2002 the LS6 went to 405 hp and the Z06 got the head-up display; the 2002 guide covers that year, and the C5 Z06 guide all four. The 2001 keeps forged wheels, where the 2002–2004 cars have cast-spun ones. In an owner’s study of self-reported LS6 valve spring failures, it shares the lowest count with the 2004, 6 of 177 each, and no 2001 NHTSA complaint describes one.

GM’s 0–60 mph figures came from its own closed-course development testing: 4.5 s manual, 5.0 s automatic, 4.0 s Z06 (kit, PDF page 27). The Z06 guide has the magazine tests for the Z06.

From the owner’s manual: an 18.5-gallon (70.0 L) tank, 6.5 quarts (6.1 L) of oil with the filter at no more than 15,000 miles or 12 months, and wheel nuts at 100 lb-ft (140 N·m). GM recommends premium, 91 octane or higher, and allows lower grades with slightly reduced acceleration. The manual’s parts list names an ACDelco 75P-7YR battery (OEM) and PTJ16R15 spark plugs (OEM) gapped at 0.060 in. GM’s kit gives the Z06 a more compact battery, so on a Z06 the label on the battery decides (battery guide).

Where GM’s papers disagree, the table follows the specification pages. The kit’s feature chart marks Z51 and F45 standard and prints a 2.75 axle, where the spec pages and price list make them options and the axle 2.73, and GM’s papers put the LS1’s peaks at different rpm, so the table leaves rpm out, as the C5 guide does. GM’s own economy figures, 18/26 automatic and 19/28 manual, used the EPA’s method of the day.

The C5’s electronic column lock locks the steering when the key comes out, but on a 2001 only a manual’s. The owner’s manual says that with the key out an automatic’s shifter locks, and “If you have a manual transmission, the steering wheel will also be locked.” Its column lock messages are marked “(Manual Transmission Only)” (PDF page 166). The 1999 and 2000 manuals say every car’s steering locks.

The recall followed that line. GM’s recall bulletin (opens in new tab) for 04V060000 (GM 04006), dated July 2004, covers certain 1997–2004 manuals, 1997–2000 automatics and 2001–2004 automatics built for European export only. A US 2001 automatic was never in it. Manual cars were, every Z06 among them: Bowling Green built 16,019 manual 2001s, though GM’s wording covers “certain” manuals, so a dealer’s VIN check settles any one car. Their remedy, a reprogrammed engine computer, became removal of the lock plate on US manuals with GM’s 2006 revision, 04006C.

Of the 2001’s 203 complaints, 57 mention the column lock: by stored VIN, 23 on coupes, 14 on convertibles and 16 on Z06s. None describes the owner’s own automatic locking. About nine describe a repeat failure, one of them a Z06 after the recall work, and five tie it to a weak battery. On a manual car, the dash names the trouble: PULL KEY, WAIT 10 SEC means take the key out for 10 seconds (drive off instead and the fuel shuts off at 1.5 mph), and SERVICE COLUMN LOCK means a tow to the dealer. GM’s 2023 bulletin PIC6522 covers the diagnosis; the full history is on the C5 guide.

Bowling Green built 35,627: 15,681 coupes, 14,173 convertibles, 5,773 Z06s, or 44, 40 and 16 percent, by Corvette Action Center’s production page (opens in new tab), the source of every count here. GM wrote before the year that 60 percent of buyers chose the automatic; the factory built 19,608, 55 percent of all 2001s. Of those automatics, 12,882 got the 3.15 axle.

GM’s price list of July 1, 2000 (opens in new tab) gave $40,475 coupe, $47,000 convertible, $47,500 Z06, with the $645 destination charge in the coupe’s price. Corvette Action Center lists different figures for several items; the table uses GM’s. RPO codes are GM’s regular production option codes, on its RPO list:

Three in four coupes and convertibles have the polished wheels (see Oil, wheels and the other 2001 weak spots) and 85 percent the head-up display. GM also sold packages, 1SB ($1,639 coupe) and 1SC ($2,544 coupe), but CAC’s package counts don’t square with its option counts: go by the codes on the label. The magnesium wheel is the rare one: 1,022 cars for 2001, against 114 for 2002.

Dark Bowling Green is the rarest 2001 color, and with Navy Blue it was gone for 2002. Inside, black leather went into 22,706 cars, Light Oak 7,278, red (Torch Red in GM’s kit, Firethorn Red in CAC’s list) 2,930, of which 1,661 are Z06s with the red accents, and Light Gray 2,713. Convertible tops were black on 9,823 cars and Light Oak on 3,802; CAC’s white count, 3,548, is probably 548.

NHTSA lists one GM campaign, the column lock, covered in The steering column that stopped locking, plus two aftermarket lamp campaigns that aren’t GM equipment. Unlike the 2000, the 2001 isn’t in the lap belt recall.

On October 22, 2026, NHTSA’s complaint file (opens in new tab) held 203 for the 2001. Beside the years either side, with this site’s approximate keyword counts of the complaint text:

The oil row is the 2001’s own. Complaints are voluntary and older cars have had longer to collect them, so read the table as a ranking. Two of the 203 look misfiled, by their VINs; the site keeps NHTSA’s count so its C5 pages agree.

GM’s bulletins for the 2001 alone, from NHTSA’s summaries, with the bulletins’ own dates:

1. 010525004 (March 2001): a yellow SERVICE TRACTION or ACTIVE HANDLING message; its update 010525004A (November 2001) covers 2001–2002.
2. 010522002 (April 2001): brakes that seem to drag after the pedal comes up, or brake lights that stay on.
3. 300401 (April 2001) and 01-601 and 010601 (June 2001): harsh automatic shifts, and damage to the 4L60-E’s 2-4 band or 3-4 clutch.
4. 020604001 (January 2002): an engine that lacks power after a full-throttle downshift and upshift.
5. 020601021 (May 2002): a whistle from the intake manifold or throttle body.
6. 051002 (May 2002): a fuel gauge that drops to empty from about half full.
7. Emission campaigns 00103 (February 2001, an incorrect emission label) and 01075 (January 2002, reprogramming uncertified calibrations).

Oil use on early 2001s

Fifteen of the 203 complaints describe oil use, all filed from May 2001 to July 2004 while the cars were new, five on Z06s and the rest on LS1s. One Z06 owner reported 2.5 quarts in 2,400 miles, another quotes GM calling a quart per 900 miles normal, and some got new rings or pistons under warranty. GM bulletins cover it: 061000 (2000, for 1997–2001), 010601023 (October 2001, 1999–2001) and its update 010601023A (June 2002, 1999–2002).

GM’s bulletins don’t say how many cars. Owners’ answers run from many to some, but not many (opens in new tab), and owners in several threads say 2002 fixed it; journalist Hib Halverson’s 2004 Z06 road test reports revised piston rings from the start of 2002 production. A 2001 that has gone 25 years without needing a quart every few hundred miles has likely shown its hand (this site’s judgment, not GM’s). Ask for the oil history and look for soot or oil in the tailpipes.

The polished wheels crack at the spokes

About 15 complaints describe cracks where a spoke meets the rim, filed from 2003 to 2019 and mostly found from a slow leak or at a tire change; of those that say, nine were rear wheels and one a front. Four name the polished wheels, none is on a Z06, and one cracked at about 75 mph on the highway. GM’s bulletin 0703100003 (March 2007) tells dealers to inspect 2000–2004 wheels for irregularities at the base of the spokes and replace them if needed. There was no recall. The 2002 had it worse, with 35.

GM’s 2001 kit calls the standard wheel cast and the polished one forged, though the 2000 kit called the 2000’s standard wheel forged. Either way, check every spoke.

Fuel smell and the gauge

Seventeen complaints describe fuel smell or a leak, most filed in 2009 or later, at or after a fill-up; one owner put a 2019 repair at $2,000 to $2,500. No GM campaign covers a 2001: GM’s tank connector coverage was for 2004s only. About eight more describe the gauge dropping toward empty, bulletin 051002’s fault.

Gearboxes, Active Handling and seats

• Automatic. Beyond the 2001-only shift bulletins, 010730043 (December 2001, 2001–2002) covers slipping or missing second, third or fourth.
• Six-speed. Bulletin 040302 (April 2002, 2001–2002) covers a reverse lockout that lets the lever into reverse on the way to fifth, and one 2001 complaint describes exactly that.
• Active Handling. Seven complaints, one of a single brake applied hard at about 75 mph. Hold the button more than five seconds for Competitive Driving mode: traction control off, Active Handling still braking.
• Seats and belts. A rocking driver’s seat (GM bulletin 020850002, 1997–2002) and belts that won’t retract turn up in the complaints.
• The generation’s items: the harmonic balancer, headlight motors, clutch fluid and leaks are on the C5 buyer’s guide.

The VIN. The plate is at the driver’s corner of the dash, and GM’s VIN chart reads 1G1YY, then the body (1 for the Z06, 2 coupe, 3 convertible), 2 for the restraints, the engine, a check digit, 1 for 2001, 5 for Bowling Green and a six-digit sequence. The chart lists only G for the engine; the owner’s manual gives G for the LS1 and S for the LS6 (PDF page 345). A Z06 has to read 1 and S; a 1999 or 2000 hardtop wearing Z06 badges reads 1 and G. The last five digits of the sequence are also stamped on the rear side of the front sill tie bar.

Labels and stamps. The door-edge label gives the build month, and the Service Parts Identification label in the glovebox lists the VIN, paint and every production option (owner’s manual): check M30 or MM6 (M12 on a Z06), the axle code, Z51, F45 or FE4, QF5 or N73, UV6 and the roof codes against the ad. The engine and transmission carry a nine-character VIN derivative, 1, 1 and 5 and the six-digit sequence, which should match the car (kit, PDF page 30).

Against a 2000. Speedway White or Quicksilver paint, chrome-flashed tips, the slimmer fob and the 1 in the VIN’s tenth place; Arctic White, Sebring Silver or plain tips mean 2000 or earlier.

Against a 2002. Navy Blue or Dark Bowling Green paint, a Speedway White Z06 or a Z06 without a head-up display can’t be a 2002, and Electron Blue can’t be a 2001. The radio proves nothing: both years offered a CD player.

1. Oil use. Ask how much it takes between changes, and look in the tailpipes.
2. Every wheel spoke, rear wheels first, where each spoke meets the rim.
3. The column lock, on a manual. Cycle the key fully out several times; ask for the recall paperwork and who fitted any bypass.
4. Dash messages during and after the drive: SERVICE ACTIVE HNDLG, SERVICE TRACTION SYS, SERVICE ABS, and the brake lights going off when the pedal comes up.
5. Automatic shifts. Smooth, with no flare or slip into second, third or fourth.
6. Six-speed. The reverse lockout working on the way to fifth, clean shifts and clear clutch fluid.
7. Fuel. A sniff around the rear after a fill-up, and a gauge that behaves on the drive.
8. The label, VIN and stamps, against each other and the ad; on a Z06, the 1 and the S.
9. Tires. Run-flats or not on a coupe or convertible, and the inflator kit on a Z06, which has no spare.
10. Records and a lift. Service history, then a shop that knows C5s, with the C5 guide’s list in hand.

From January 1 to October 21, 2026, Bring a Trailer (opens in new tab) listed 18 cars titled 2001 and sold 14. Leave out the supercharged, twin-turbo and engine-swapped cars and seven stock cars remain, all sold, for $14,500 to $22,000: a median $20,000 by this site’s count. Six were convertibles, from $14,500 (29,000 miles) to $22,000 (8,000 miles); the one coupe brought $17,750 in April.

Three stock Z06s sold: $30,750 (8,000 miles, June), $37,250 (12,000 miles, September) and $31,500 (12,000 miles, October), a median $31,500. The 2002 guide gives $31,125 for 2001 Z06s over almost the same months because it also counts a 34,000-mile car with a targa roof conversion, sold for $16,500 in May. This page leaves roof-converted cars out; both figures are right for their samples. From October to December 2025, six stock 2001 Z06s sold there, five for $17,800 to $24,250 and a 49-mile car for $41,500. In the 2026 window, a stock 2000 brought a median $18,000, a 2002 coupe or convertible $20,750 and a 2002 Z06 $28,000. Small samples, and auction cars skew clean and low-mile.

Hagerty’s valuation tool (opens in new tab), archived on February 7, 2026, put a 2001 in #3 (good) condition at $17,000 coupe, $18,600 convertible, the same as a 2002. Its single-car pages for the 2000 took 10 percent off for an automatic (see the 2000 guide), so these are probably six-speed values. It lists no Z06, and classic.com’s 2001 page wouldn’t load. These are past sales and valuations, not a forecast.

For most buyers, the 2001 to buy is an automatic coupe or convertible with an oil history that checks out. It has the torquier LS1, standard Active Handling, a brake module that can usually be rebuilt and, unlike any C5 automatic before it, a column that doesn’t lock when the key comes out. At a $20,000 auction median, that’s America’s sports car with 360 lb-ft from an aluminum V8. Check every spoke, and pay for good records, not low miles alone.

For a clutch pedal, a six-speed coupe with Z51 is the sharper car; read its column lock recall record before the test drive.

The Z06 is for the buyer who, of course, wants more. It’s the only year of the 385 hp LS6, 20 hp short of a 2002, but it has the forged wheels and, with the 2004, the fewest reported valve spring failures of any Z06 year. On Bring a Trailer in 2026 its median ran $11,500 above a stock coupe or convertible. That buys the LS6, the M12 and the titanium; know the oil use and see the recall work done before paying it, then find a track day and let the LS6 run to 6,500 rpm.

Skip any 2001 whose owner can’t say how much oil it uses. The years-to-avoid guide ranks it against every C5 year, the best Corvette years guide against every generation, and the C5 vs C6 guide shows what the next step up costs.
