![[VIDEO] Real World Performance Testing of the 2027 Corvette Grand Sport](https://www.corvetteblogger.com/images/content/2026/07/071626_9.jpg)
A couple weeks back we got the first performance numbers for the LS6 in the new 2027 Corvette Stingray and we are still amazed that the base car in the C8 Corvette line up features a 200+ MPH top speed. In addition to that, Chevrolet revealed the 2027 Stingray is capable of a 2.8-second 0-60 MPH time and it can run the quarter mile in 11.0 seconds at 124 MPH.
While Chevrolet released those numbers for the Stingray, we haven’t seen official numbers yet for the 2027 Grand Sport. But now that the car has started shipping, one turned up at Paragon Performance and now we have some real world test numbers to review thanks to Korey who took out the car for a night drive.
Korey posted three different videos to Instagram showing off these three performance stats: 0-60 MPH, 60-130 MPH, and a quarter mile run. All were done in a Grand Sport with 1/4 tank of fuel. The car was spec’d with the Z52 Sport Package which adds the Michelin Pilot Sport 4S summer performance tires. Korey also put the GS on the scales where it registered exactly 3,727 lbs.
As far as those performance tests go, we are so used to seeing the new ZR1 and ZR1X obliterate time clocks everywhere, so we sort of need to do a mental reset when it comes to looking at these Grand Sport numbers. The Grand Sport is based on the Stingray, but the widebody and wider tires will cause it to run a little slower than the new Stingray. Each was done with a Draggy recording the times and Korey notes that the Draggy doesn’t include the rollout in these tests while the official Chevy numbers include the rollout. And lastly, these runs were done on a street at night, so no prepped surface or burnouts to warm the tires.
Here is what Korey shared:
Grand Sport 0-60 MPH – 3.21 Seconds
Grand Sport 60-130 MPH – 10.18 Seconds
Grand Sport Quarter Mile – 11.32 Seconds
Thanks to Korey and Paragon Performance for sharing these numbers. You can see all three videos on their instagram page. Technically, (and I’m laughing to myself as I type this ridiculous statement) these are the current C8 Grand Sport world records until someone comes along and beats them with video and timeslips for proof.

I called it back in 2023. The C8GS is no quicker than the C8SR. It isn’t even quicker than the LT2 C8SR.
Proof positive that everyone is paying that $15,000 extra base MSRP for looks. The performance delta from C6 and C7 generations has inverted.
For the extra $15k you get the Widebody Design & Aero: A noticeably wider track and bodywork to accommodate larger 275/30ZR20 front and 345/25ZR21 rear tires, along with aggressive aerodynamic enhancements.
Performance Suspension: Standard Magnetic Ride Control (often an expensive add-on for the Stingray) and a track-tuned wishbone suspension setup.Brembo Brakes: Larger, track-capable brake rotors and calipers with optional carbon-ceramic upgrades.
It’s a deal and they’ll sell of ton of them 🏁

0-60 @ 2.75 and 1/4mi @ 10.95
Ok……….
Why does a C8 GS weigh 240 lbs more than a C7 GS?
No drive shaft, no exhaust running front to back, should weigh less, not more.
@John Street
I’m glad AI copy/paste works so well for replies.
None of that “upgrade” makes a lick of difference outside of the caliper/rotor upgrade from base model SR. But thanks for handily displaying the copium that all of the GS buyers will be mainlining. This is the same crowd that screamed bloody murder that the ER was piss expensive, and now they’re falling all over themselves to plunk an extra 15k down on something that provides zero performance gain.
I’ll also be shocked if any apples to apples comparison of LS6 powered cars actually shows a lick of advantage on acceleration for the GS.
LOL, I’ll just wait for the GrandSportX . I need real performance numbers . 200 + out the door. And then some !
Such hate?
First this was one test on a back road on a hot night. Not exactly SAE standards. GM numbers are SAE certified numbers.
Second this is not a drag car. The better brakes, tires and wider track are for track time. This is made to do laps not 1/4 miles.
The truth is most buy the car due yo the wide vary at a 30k less price of a Z06. Few will ever experience the 3 tenths difference between it and the Z anyways.
The Stingray will be the 1/4 mile car as it is lighter and narrow but you need the Z51 for the gearing.
The Corvette line is like a tool box and each has a specific job it is up to the customer to fit the need and what they can afford.
Note too the same car varied much on the dyno. They found the new LS is sensitive to higher
temps.
The way some act it is no wonder some folks hate to deal with Corvette people. Buy what you like and want then respect others choices.
I’m ordering the GS in track mode as it will be a Z07 with just a little less power and about $35k less vs the same options on a Z. Also not a fan of the z engine noise inside. It is cool at first but gets old after a while.
“Why does a C8 GS weigh 240 lbs more than a C7 GS?”
Because the C8 chassis was built to handle 1064 and 1250 hp maybe?
I am starting to seriously question all these paragon tests. C8 been out for six years, quarter million units sold and now they are discovering the C8 barely clears the 4 seconds mark?
I have an E-Ray and a plussed C6 and no way they are the same and yet Paragon basically states that they are! Nope
