The 2027 Corvette Grand Sport comes in three equipment levels, 1LT at $86,000, 2LT at $93,100 and 3LT at $97,750 before the $2,495 destination charge, and every one of them makes the same 535 horsepower. That is the fact that shapes this entire decision. On most cars the trim ladder is also a power ladder, so climbing it buys speed. Here it buys seats, audio, driver aids and cabin materials, and nothing else.

Jim Norton T-Town Chevrolet stocks the Grand Sport and orders to spec for buyers across Tulsa, Broken Arrow and Glenpool. This page covers each equipment level in full, a side-by-side matrix, the two comparisons buyers actually make, and what each step up costs against what it delivers.

2027 Corvette Grand Sport Trim Lineup at a Glance

Three levels, $11,750 from bottom to top, one engine throughout.

Level	Starting MSRP	Who it is for
1LT	$86,000	The buyer who wants the LS6 and the wide body, and does not need the cabin to do anything else
2LT	$93,100	The buyer who drives it regularly and wants the driver aids, the bigger audio system and the head-up display
3LT	$97,750	The buyer who wants the interior finished to match what the car costs

Prices exclude the $2,495 destination charge. A 1LT coupe therefore lands at $88,495 delivered and a 3LT coupe at $100,245.

Trim-by-Trim Breakdown

Grand Sport 1LT, from $86,000

The 1LT is a complete car, not a stripped one. It carries the full 535-horsepower LS6 6.7L V8, the eight-speed dual-clutch transaxle, Magnetic Selective Ride Control 4.0, the Z06-derived wide body with its integrated rear spoiler, and the 20-inch front and 21-inch rear forged aluminium wheels in Pearl Nickel. Inside it has eight-way power GT1 seats in genuine Mulan leather, a 10-speaker Bose audio system, a wireless phone charger, an HD rear vision camera and a rear camera mirror. Wireless phone projection is standard, as it is on every level.

Coupe or convertible, and the coupe's roof panel lifts out. The Competition Sport seat is available here, and on 1LT specifically the performance textile covers the entire seat rather than just the high-wear areas. Both the Z52 Sport and Z52 Track Performance Packages can be ordered on a 1LT, which means the fastest configuration in the range does not require the most expensive equipment level.

Grand Sport 2LT, from $93,100

The 2LT adds the equipment you notice on an ordinary drive rather than a fast one. Audio steps up to the 14-speaker Bose Performance Series system. The seats gain heating, ventilation and power lumbar and wing adjustment, which is what turns a two-hour run down US-75 from an event into a drive. A head-up display arrives, and so do rear cross traffic alert and side blind zone alert, both of which matter more than usual on a car 79.7 inches wide with the sightlines of a mid-engine coupe.

The Performance Data Recorder becomes standard at this level, integrating lap timing, automated coaching tips and side-by-side video comparison into the car's own screens. The GT2 seat, with carbon-fibre trim, a seatback halo and Napa leather, becomes available.

Grand Sport 3LT, from $97,750

The 3LT is about materials. The GT2 seat in Napa leather becomes standard rather than optional. The instrument panel and doors are wrapped in custom leather, and sueded microfiber covers the upper interior trim. Fourteen interior colour combinations open up, including the asymmetrical Santorini Blue and Adrenaline Red schemes, and those two unlock the split configuration that pairs a Competition Sport seat for the driver with a GT2 for the passenger.

This is also the level Chevrolet used for its own Launch Edition treatment, with the Santorini Blue dipped cabin, custom stitching, embossed headrest logos and a waterfall badge plaque, offered only on the inaugural 2027 cars.

Side-by-Side Comparison Matrix

Feature	1LT	2LT	3LT
Starting MSRP	$86,000	$93,100	$97,750
Engine	6.7L LS6 V8, 535 hp and 520 lb-ft, all three levels
Drivetrain	Rear-wheel drive, eight-speed dual-clutch, all three levels
Body styles	Coupe with removable roof panel or convertible, all three levels
Standard seat	GT1 Mulan leather	GT1 Mulan leather	GT2 Napa leather
GT2 seat	not std	available	standard
Bose audio	10-speaker	14-speaker Performance Series	14-speaker Performance Series
Heated and ventilated seats	not std	standard	standard
Head-up display	not std	standard	standard
Blind zone and cross traffic alerts	not std	standard	standard
Performance Data Recorder	not std	standard	standard
Wrapped instrument panel and sueded upper trim	not std	not std	standard

"Not std" means the feature is not standard equipment at that level. It does not mean the feature cannot be ordered.

Common Corvette Grand Sport Trim Comparisons

Grand Sport 1LT vs 2LT

This is the real decision in the range, and it costs $7,100. What you get is the 14-speaker Bose system, heated and ventilated seats with power lumbar and wing adjustment, the head-up display, the Performance Data Recorder, and rear cross traffic and side blind zone alerts. The dividing line is how you intend to use the car. A garage-kept weekend car that comes out on clear Saturdays does not need ventilated seats to be enjoyable, and the 1LT has the same engine, the same chassis and the same wide body.

A car that gets driven into downtown Tulsa on weekday evenings and parked in structures is a different proposition. The blind zone and cross traffic alerts do genuine work reversing a wide, low car out of a tight bay, and the head-up display keeps your eyes up on the Broken Arrow Expressway. For most buyers who plan to drive the car often, the 2LT is the one that fits.

Grand Sport 2LT vs 3LT

This step costs $4,650 and buys materials rather than capability. The GT2 Napa leather seat moves from optional to standard, the instrument panel and doors get wrapped in custom leather, sueded microfiber goes across the upper trim, and 14 interior colour combinations open up against the standard set.

Order a GT2 seat on a 2LT and you have already spent part of the difference, which makes the 3LT the tidier choice for anyone who wanted that seat anyway. The buyer who spends most of their time looking at the cabin, and who cares that the asymmetrical colour schemes are available, is the buyer this level was drawn for.

The Grand Sport Value Verdict and Step-Up Guide

The 2LT is the volume level and the one most of our Corvette orders settle on, because it adds the equipment a regularly driven car uses every trip. The 1LT is the one for the buyer whose priority is the engine and the chassis, and it takes both performance packages, so it can be the quickest Grand Sport on the lot. The 3LT is for the buyer who wants the cabin finished to the level of the price.

Step	Cost	What it adds
1LT to 2LT	$7,100	14-speaker Bose, heated and ventilated seats, head-up display, Performance Data Recorder, blind zone and cross traffic alerts
2LT to 3LT	$4,650	Standard GT2 Napa leather seats, wrapped instrument panel and doors, sueded microfiber upper trim, 14 interior colour options
1LT to 3LT	$11,750	Everything in both steps above

The two performance packages sit alongside this ladder rather than on top of it. Z52 Sport is the road-going option, adding uprated brakes and a high-performance tyre. Z52 Track is the circuit-focused one: carbon-ceramic rotors, Cup 2 R rubber, the quad centre exhaust, and the carbon-fibre aero kit with its high wing, dive planes, rockers and front splitter. Either can be ordered at any equipment level.

Which Grand Sport Trim Is Right for You?

If this is a weekend car that lives in a garage

The 1LT coupe. Same engine, same chassis, same wide body, and the money saved covers the Z52 Sport Performance Package with room left over.

If you will drive it several times a week

The 2LT. Ventilated seats through an Oklahoma August and the blind zone alerts in traffic are the two things you will use on every trip.

If you are booking track days

Any level with the Z52 Track Performance Package, and the 2LT for its Performance Data Recorder, which puts lap video and coaching on the car's own screens.

If the cabin is the point

The 3LT, for the standard GT2 Napa leather seats, the wrapped panel and doors and the 14 colour combinations.

If you want all-weather traction

Look at the Grand Sport X, which adds an electric front axle and all-wheel drive at 721 combined horsepower. The two are compared in full on the Grand Sport versus Grand Sport X page.

Grand Sport Trim FAQs

How many Corvette Grand Sport trims are there?

Three: 1LT, 2LT and 3LT. Each is offered as a coupe with a removable roof panel or as a convertible.

Do the higher trims make more horsepower?

No. All three make 535 horsepower and 520 lb-ft from the same naturally aspirated 6.7L LS6 V8. The ladder changes cabin equipment, audio and driver aids.

What does it cost to step from 1LT to 2LT?

$7,100. That buys the 14-speaker Bose Performance Series audio, heated and ventilated seats, the head-up display, the Performance Data Recorder and the blind zone and cross traffic alerts.

Which Grand Sport trim is the best value?

The 2LT for a car that gets driven regularly, because everything it adds is equipment you use on an ordinary trip. The 1LT for a weekend car, since it carries the identical powertrain and chassis.

Can I get the track package on the base trim?

Yes. Both the Z52 Sport and Z52 Track Performance Packages can be ordered on any equipment level, including the 1LT.

What is the difference between the GT1 and GT2 seats?

The GT1 is wrapped in genuine Mulan leather and built for long-distance comfort. The GT2 adds carbon-fibre trim and a seatback halo and is wrapped in Napa leather. GT1 is standard on 1LT and 2LT; GT2 is available on 2LT and standard on 3LT.

Is the head-up display available on the 1LT?

It is standard from 2LT upward on the Grand Sport. On the Grand Sport X it is standard from 1LT.

Should I order or buy from stock?

Both work. Allocation is limited, so cars on the lot move quickly and a specific colour and seat combination is usually an order. Talk to us early if you have a build in mind, and see the Grand Sport questions page for how ordering works here.
