C7 Corvette specs (2014–2019): horsepower, length, weight, 0–60 and colors by year

A C7 makes 455 hp as a Stingray, 460 hp as a Stingray with the performance exhaust or as a Grand Sport, 650 hp as a Z06 and 755 hp as a ZR1. Those are GM’s SAE-certified ratings, and none changed during the run. All three engines displace 6.2 liters, 376 cubic inches (6,162 cc), on a 4.06 x 3.62 in bore and stroke.

Sources: GM’s archived spec sheets for the 2016 Stingray (opens in new tab), 2015 Z06, 2018 Grand Sport and 2019 ZR1; owner’s manual engine data, 2014, page 337, 2015, page 352 and 2019, pages 328 and 329 (the VIN code is the eighth character); GM’s 2019 order guide, page 27, for the LT5’s dual injection. RPO is GM’s regular production option code, and NPP is the code for the performance exhaust.

GM’s spec sheets give the LT1 and LT4 a 6,600 rpm redline, and its 2017 brochure gives the Grand Sport the same; the ZR1 sheet gives none. From 2015 the Z51 package included the NPP exhaust, so every 2015–2019 Z51 Stingray is a 460 hp car; the 2014 Z51 package didn’t (2014 order guide, page 3; 2016 order guide, page 4; 2015 guide). GM’s preliminary sheet of January 2013 estimated the LT1 at 450 hp and 450 lb-ft, figures the certified ratings replaced before sale.

LT1 vs LT4

Same block dimensions, same 6.2 liters. The LT4 adds a supercharger, drops compression from 11.5:1 to 10.0:1 and makes 650 hp and 650 lb-ft: 190 to 195 hp and 185 to 190 lb-ft more than an LT1, depending on the exhaust (this site’s arithmetic). Its torque peaks 1,000 rpm sooner, every LT4 has a dry sump, and GM’s sheets call premium “required” for the LT4 where the LT1 only recommends it. The Grand Sport’s 5 hp over a base Stingray isn’t a different engine: it’s the performance exhaust, standard on that car. The C7 Z06 guide covers the LT4 and its track-heat history, and the C7 ZR1 guide the LT5.

A C7 Stingray is 176.9 in long, 73.9 in wide and 48.6 to 48.9 in high depending on the GM document, on a 106.7 in wheelbase. The Z06 and Grand Sport are 77.4 in wide and, by most of GM’s documents, 177.9 in long. The ZR1 is 179.8 in long.

Sources: GM’s spec sheets for the 2014 Stingray, 2015 and 2018 Z06, 2018 Grand Sport and 2019 ZR1; GM’s order guides for 2014 (PDF pages 52, 60 and 61), 2016 (page 120), 2017 (page 123) and 2019 (page 236) (opens in new tab); GM’s 2017 brochure, page 46.

In feet and inches, for a garage, a trailer or a car cover: 14 ft 8.9 in for a Stingray, 14 ft 9.9 in for a Z06 or Grand Sport and 14 ft 11.8 in for a ZR1 (this site’s arithmetic). Covers are cut by generation, and the car cover guide deals with fit; C7 vs C8 sets these dimensions against the mid-engine car. No GM ground clearance figure turned up.

GM’s two lengths for the wide body. GM’s own documents disagree. Seven give the Z06 and Grand Sport 177.9 in: the 2015 Z06 coupe and convertible sheets, the 2016 Z06 sheet, the 2016, 2017 and 2019 order guides and the 2017 brochure. GM’s 2018 Z06 and Grand Sport sheets print 176.9 in and 4,493 mm, the Stingray’s figures to the millimeter. That looks like the Stingray’s line carried over, but that’s this site’s reading; GM never says which is right. This page goes with the seven.

By GM’s curb weights, a C7 runs from 3,298 lb (Stingray coupe) to 3,618 lb (ZR1 convertible). Every GM document read for this page agrees, for every model and year.

Sources: GM’s spec sheets and order guides as listed, and GM’s 2017 brochure, page 46 (opens in new tab).

The wide body costs weight. A Grand Sport coupe is 130 lb heavier than a Stingray coupe, a Z06 another 96 lb, and the ZR1 only 36 lb more than the Z06. A convertible adds 58 to 64 lb (this site’s arithmetic throughout).

No GM document read here defines curb weight or says what options the weighed car carried. GM’s 2014 order guide left the Z51 coupe and convertible “TBD”, and no Z51 figure turned up later, so 3,298 lb is GM’s Stingray figure, not a Z51’s. Weight distribution, front to rear, is 50/50 on GM’s Stingray and Z06 sheets; the 2017 brochure prints 49/51 for the Stingray and Grand Sport.

Scales run a little heavier. Car and Driver weighed a 2015 Z06 coupe with Z07 and the automatic at 3,558 lb, 34 lb over GM’s figure, and a 2019 ZR1 coupe with ZTK at 3,671 lb, 111 lb over. Both carried their performance packages; GM’s figures don’t say whether they do.

GM’s 0–60 claims run from 3.8 seconds for a 2014 Stingray Z51 to 2.95 seconds for a Z06 with the Z07 package and the automatic. GM published one top speed for the generation: 212 mph for the ZR1 low-wing coupe.

What GM claimed

Sources: GM’s Z06 shipping release (opens in new tab) and GM’s other releases, brochure and Playbook, listed in Sources. The Playbook is GM’s guide for salespeople.

Name the gearbox before quoting a C7’s 0–60. GM’s 3.6 seconds for the Grand Sport is with the eight-speed automatic and Z07, and so is the Z06’s 2.95; the manual Z06 is GM’s 3.2. The 2014 release’s 3.8 seconds names no gearbox. GM’s grip and braking claims: 1.03 g and 107 ft from 60 mph for the 2014 Z51, 1.2 g and 99.6 ft for the Z06 with Z07.

No GM top speed turned up for any Stingray, Grand Sport or Z06, and the table doesn’t borrow one. The owner’s manuals’ 174 mph (Z51) and 184 mph (Grand Sport, Z06 and ZR1) are limits for track use at 26 psi with only the driver aboard (2019 owner’s manual, page 164), not what the car will do.

What the magazines measured

Sources: Car and Driver’s ZR1 test (opens in new tab) and its other pages listed in Sources; MotorTrend’s Z06 first test; the Grand Sport figures as Corvette Action Center reported Car and Driver’s test. Car and Driver’s top speeds are its own estimates, not runs.

The tests landed on GM’s numbers. The automatic Z06 ran 2.9 seconds against GM’s 2.95, and the manual Z06 matched GM’s 3.2 to the tenth. The manual Grand Sport’s 3.8 isn’t a miss against GM’s 3.6, which is for the automatic. And the ZR1 crossed the quarter-mile line at 135 mph: line one up beside anything on the street and the far end of the strip arrives in a hurry.

Every C7 offered a seven-speed manual with Active Rev Match, which matches engine speed to the next gear for you. The paddle-shift automatic was a six-speed for 2014 only and an eight-speed in every model for 2015–2019.

Sources: GM’s spec sheets for the 2014 and 2016 Stingray, 2015 Z06, 2018 Grand Sport and 2019 ZR1; GM’s 2014 order guide (PDF pages 3 and 14) and 2019 order guide (pages 9, 24, 27 and 61); GM’s eight-speed release (opens in new tab) of August 2014. GM’s 2017 brochure prints the same ratios to three decimals.

The eight-speed’s pitch, in GM’s own numbers: a 4.56 first gear against the six-speed’s 4.03, a 0.65 top gear against 0.67, and a taller 2.41 axle in place of 2.56. More shove off the line, fewer revs on the highway. GM’s July 2014 sheet for the 2015 Stingray, captured before the gearbox shipped, printed a preliminary set (4.60 to 0.69, reverse 4.06); every later GM document gives 4.56 to 0.65.

In the C7 buyer’s guide, Seven-speed manual or eight-speed automatic covers how rare the manual is and which to buy, and Known C7 problems by model year covers the eight-speed’s shudder history. The 2014-only six-speed automatic has its story in the 2014 guide.

The C7 bolt pattern (lug pattern) is 5 x 120.65 mm (5 x 4.75 in), per wheel fitment guides: five studs on a 4.75-inch circle, around a 70.3 mm center bore. That figure comes from the wheel trade, here ThreePiece.us (opens in new tab), a wheel retailer; no owner’s manual, order guide or spec sheet read for this page prints a bolt circle. The nut torque is GM’s: 100 lb-ft (140 N·m) in all six C7 owner’s manuals.

Sources: GM’s spec sheets for the 2014 Stingray, 2015 Z06, 2018 Grand Sport and 2019 ZR1; GM’s order guides for 2017 (PDF pages 4, 9 and 101), 2018 (page 4) and 2019 (pages 7, 27 and 61); owner’s manuals for the nut torque, from 2014 (page 336) to 2019 (page 328).

Every C7 came on Michelin Pilot Super Sport summer tires, with Pilot Sport Cup 2s in the Z07 package (Grand Sport and Z06) and the ZTK package (ZR1). For 2018 the Z51’s 19- and 20-inch wheels and tires became standard on every Stingray (2018 guide). GM’s ZR1 sheet and order guide disagree on the front wheel’s width; the C7 ZR1 guide goes with the order guide’s 10.5 in.

Run-flats, no spare. Every C7 left the factory on run-flat tires, the Cup 2s included. GM’s order guides list the Z07 and ZTK tire as “Michelin Pilot Super Sport Cup 2 summer-only, run-flat”, and every C7 owner’s manual says the car “when new, had run-flat tires” and carries no spare (2019, page 267). GM’s spec sheets just don’t repeat the word after “Cup 2”. A C7 since moved to conventional tires needs a plan for a flat.

Tire pressure. The manuals give no everyday figure: they point to the Tire and Loading Information label on the driver’s door. At 175 mph or more they call for the tire’s maximum sidewall pressure or 38 psi, whichever is lower (2014, page 281; 2019, page 276), and 26 psi on track.

The wide-body wheels are the C7’s best-known weak spot. Cracked Z06 and Grand Sport wheels, GM’s reimbursement program and the class action are under Known C7 problems by model year in the C7 buyer’s guide.

By the owner’s manuals, a wet-sump LT1 (a Stingray without Z51) takes 7.0 qt (6.6 L) of oil with a filter, and every dry-sump engine takes 9.8 qt (9.3 L): the LT1 in a Z51 or Grand Sport, the LT4 and the LT5. GM’s spec sheets print 9.75 qt for the dry sump, the figure the C7 buyer’s guide gives. Both are GM’s numbers, a twentieth of a quart apart; this page follows the manuals.

Sources: the owner’s manual capacities pages linked in the table; their fluids pages (2014, 328 and 329; 2015, 345; 2017, 317; 2018, 314; 2019, 322 and 323); and their fuel pages (2014, 224; 2015, 235; 2017, 214 and 215; 2019, 213 and 214). The 2016 manual (pages 313 and 207) matches 2015, and the 2018 manual (pages 319, 211 and 212) matches 2017.

GM’s other paper differs in two places. Its spec sheets and order guides give the tank as 18.5 gal every year, where the 2015–2019 manuals say 18.6, and the 2015–2016 sheets give 11.3 qt of coolant where the manuals say 11.8. Go by the manual for the year. The manuals give no fill quantities for the gearboxes or the rear axle.

The 2014 manual warns that fuel below 91 octane may damage the LT1, and the LT4 manuals say the same of the LT4. The 2014 and 2015 manuals recommend Mobil 1 for the dry-sump engines and Mobil 1 15W-50 for track use (2014, page 243). For 2019 GM switched the factory fill to 0W-40 (2019, page 238); the bulletin that approves it for every 2014–2019 LT1, LT4 and LT5 is in the C7 buyer’s guide.

By the EPA’s current figures, a C7 Stingray or Grand Sport gets 15 to 17 mpg city and 25 to 29 highway, a Z06 13 to 15 city and 21 to 23 highway, and the ZR1 12 or 13 city and 19 or 20 highway. City / highway / combined:

The Grand Sport shares the LT1 records. Every C7 rating uses the EPA’s current test method, but the EPA revised its calculations for 2017 (opens in new tab) and adjusted earlier ratings to match. That’s why GM’s 2013 launch release and its 2014–2016 Stingray sheets say 17 city and 29 highway for the manual: that was the original label, and the EPA now lists 17/28.

Two gaps stay unexplained. The LT1’s ratings drop for 2017, to 16/25 for the manual and 15/26 for the automatic, and no GM or EPA document read for this page says why. And GM’s sheets give the 2015–2016 Z06 automatic 13/23, where the EPA’s 2015 record says 13/21. GM’s 2018 Grand Sport sheet prints its own estimates, 16/25 manual and 15/26 automatic, where the EPA says 16/25 and 15/25. The EPA marks every Z06 automatic and both ZR1s as gas guzzlers. Still, 650 hp and 22 mpg on the highway: the manual Z06’s rating never budged.

GM listed ten exterior colors at the start of each C7 model year, and with the mid-year swaps that makes 22 across the generation (this site’s count). Four ran all six years: Arctic White, Black, Torch Red and Blade Silver. RPO codes in parentheses:

Sources: GM’s order guides for 2014 (PDF pages 46 and 47), 2016 (108), 2017 (113) (opens in new tab), 2018 (135 and 136) and 2019 (205); GM’s 2015 Stingray overview; the mid-year changes and counts as Corvette Blogger and Corvette Action Center reported them, recorded in each year’s guide.

GM’s names shift between documents: the 2016 guide calls Laguna Blue “Laguna Blue Metallic Tintcoat”, Admiral Blue picks up “Metallic” from 2018, and GM’s paperwork calls Shadow Gray “Dark Shadow Metallic”. Tintcoats and some metallics cost extra, per the order guides’ footnotes. Three special editions wore their own colors: the 2014 Premiere Edition (Laguna Blue coupes, Lime Rock Green convertibles; 2014 guide), the 2017 Grand Sport Collector Edition in Watkins Glen Gray with a Tension Blue interior (2017 guide) and the 2018 Carbon 65 Edition in Ceramic Matrix Gray (2018 guide). The 2016 and 2019 guides cover those years’ late colors.

Bowling Green built 189,507 C7s, by this site’s sum of the yearly totals, among them 39,940 Z06s, 26,280 Grand Sports and 2,953 ZR1s. Each year links to its own guide, where the options, packages and changes live.

Sources: production from Corvette Blogger’s and Corvette Action Center’s yearly reports and GM’s 2019 year-end data via the National Corvette Museum; prices as each year’s guide gives them, with GM’s 2014, 2015 Z06 and 2019 ZR1 releases where GM published one. Each row adds up to its year’s total (this site’s arithmetic).

The 2018 run was short, 9,686 cars ending in January 2018, and the 2019 model year ran 20 months; the year guides explain both. Destination charges moved too: $995 for 2015–2017 cars and early 2018s, then $1,095 for 2018 cars built after the plant restarted and for 2019. Compare stickers on the same basis before calling one year’s price a bargain.

That’s the C7 by the numbers. For how they drive, which year to buy and what one costs now, start with the C7 buyer’s guide, then the Grand Sport, Z06 and ZR1 guides; C6 vs C7 sets the C7 beside the generation before it.
