New Chevrolet Corvette Grand Sport Debuts with Massive Power Upgrade
Jordan Mulach | March 29, 2026
The automotive world is buzzing with the reveal of the 2027 Chevrolet Corvette Grand Sport, a vehicle that promises a significant leap forward in performance while maintaining the iconic design DNA that has captivated enthusiasts for decades. For fans of the legendary American sports car, this is more than just an update; it’s a redefinition of what’s possible when cutting-edge engineering meets automotive heritage.
The Heart of the Beast: The All-New LS6 Engine
At the core of the 2027 Corvette Grand Sport lies the revolutionary sixth-generation General Motors small-block V8 engine, designated the LS6. This isn’t just a minor tweak to an existing powerplant; it’s a ground-up overhaul designed to deliver unprecedented power and torque.
This new heart replaces the LT2, currently found in the standard Corvette Stingray. The displacement has been increased to a formidable 6.7 litres, giving it a significant edge over its predecessor’s 6.2-litre capacity. The results are staggering: the LS6 engine delivers a beefy 399kW of power and a massive 705Nm of torque. This isn’t just a new engine; it’s the most torque-rich, naturally aspirated Corvette engine ever produced by General Motors.
To put that into perspective, the standard Corvette Stingray’s LT2 engine produces 365kW and 630Nm. The Grand Sport is not just an incremental improvement; it’s a generational leap.
Powering the Grand Sport
When combined with the electric assist from its hybrid system (a feature previously exclusive to the E-Ray), the Grand Sport pushes its combined output to a staggering 538kW. This is a substantial 50kW increase over the E-Ray, positioning the Grand Sport firmly in the realm of ultra-performance machines.
This immense power is routed to the wheels through a lightning-fast eight-speed dual-clutch automatic transmission. Chevrolet claims the ECU controlling this powertrain is an astonishing 44 times faster than the LT2’s system, ensuring immediate throttle response and razor-sharp precision.
Cost and Performance Analysis
While the exact pricing for the 2027 Corvette Grand Sport has not yet been announced, industry insiders suggest that this significant performance upgrade will come at a premium. However, the added power and technological advancements justify the expected increase in cost. When compared to similar offerings in the luxury sports car segment, the Grand Sport offers a compelling value proposition. Buyers considering a high-performance vehicle should factor in the expected pricing increase, but also consider the long-term value this investment offers in terms of driving experience and resale value.
Suspension and Handling
The Grand Sport is positioned as the sharper, more performance-oriented variant of the Stingray, bridging the gap to the track-focused Z06. It comes standard with Magnetic Ride Control and a touring suspension setup, offering a balance between comfort and performance.
However, buyers seeking an even more thrilling experience can opt for the Z52 Performance Package. This upgrade includes the stiffer suspension and larger brakes from the Z06, transforming the Grand Sport into a track-ready beast. For those who truly live on the edge, the Z52 Track Performance Package offers carbon-ceramic brakes, sticky Michelin Pilot Sport Cup 2R tyres, and additional aerodynamic enhancements.
What This Means for You
For performance enthusiasts, the availability of these advanced performance packages is a significant selling point. Whether you prioritize comfort for daily driving or the raw performance of the track, the 2027 Corvette Grand Sport offers the flexibility to cater to your needs. This means that if you are considering a Corvette, you no longer have to choose between comfort and performance; you can have both.
Exhaust Systems
Also available on the updated Stingray, the Grand Sport offers buyers the option of the quad-centre exit exhausts. This distinctive design, previously unavailable on the LT2-equipped car, adds to the visual appeal and audible drama of the LS6 engine.
Wheels and Tyres
Standard equipment for the 2027 Corvette Grand Sport includes 20-inch front wheels and 21-inch rear wheels, wrapped in Michelin Pilot Sport All-Season 4+ tyres. For those who want to push the performance envelope, Michelin Pilot Sport 4S rubber can be optioned as well.
The factory-fit wheels are a classic 10-spoke forged aluminium design. However, Chevrolet is also offering five-spoke carbon-fibre rims, understood to be produced locally in Australia by Carbon Revolution. This adds a touch of cutting-edge technology and weight savings to the Grand Sport.
Styling and Heritage
Chevrolet has linked the C8 Grand Sport to its lineage with specific ‘hash marks’ on the rear wheel arches, a nod to its C2, C4, C6, and C7 predecessors. The Admiral Blue Metallic paintwork, strongly associated with the Grand Sport, has also made a triumphant return.
A new finish, Pitch Gray Metallic, will be available across the wider 2027 Corvette lineup. Additionally, the asymmetrical Santorini Blue and Jet Black interior upholstery, first seen in the Z06, will be offered on the Grand Sport, adding a touch of sophistication to the performance-focused interior.
The 2027 Corvette Lineup Overhaul
It’s not just the Grand Sport that’s getting an upgrade. Chevrolet has announced that the LS6 engine will replace the LT2 in the standard Corvette Stingray. The entry-level model is set to receive a host of other improvements for the 2027 model year.
These upgrades include an updated Magnetic Ride Control calibration, a shorter final drive ratio for the Z51 Performance Package, and Michelin Pilot Sport S 5 tyres for the latter. These changes signal a commitment from Chevrolet to elevate the entire Corvette lineup, ensuring that every variant benefits from the latest technological advancements.
What This Means for Australian Buyers
The burning question for Australian enthusiasts is whether the updated 2027 Corvette will be available in our region. A spokesperson for GM’s Australian outpost, GMSV, told Torquecafe: “At this time, we have no announcements to make on future models for the ANZ region.”
This leaves Australian buyers in a state of uncertainty. While the performance gains are undeniably exciting, it remains unclear if and when the updated Chevrolet Corvette will come to Australia. This ambiguity has led many potential buyers to explore alternative options, while others remain hopeful that General Motors will bring this extraordinary machine to our shores in the near future.
Should You Buy, Wait, or Rent/Invest?
For those in Australia considering the 2027 Corvette, the decision is complicated. On one hand, the performance enhancements of the Grand Sport are staggering, and waiting for an official release could mean missing out on one of the most exciting sports cars of the year. On the other hand, if the Corvette does not come to Australia, buyers will be forced to look for alternatives, which may not offer the same blend of performance, heritage, and iconic status.
Best Financial Strategies Right Now (2027)
Given the uncertainty surrounding the availability of the 2027 Corvette in Australia, there are several financial strategies that potential buyers should consider.
One option is to explore the secondary market for existing Corvette models. While the Grand Sport is a new offering, there may be opportunities to acquire previous-generation models at a lower price point. However, buyers must be cautious and ensure they are getting a good deal, as prices can fluctuate.
Another option is to consider leasing instead of buying. Leasing allows buyers to enjoy the latest performance without being tied down to a long-term commitment. This is a particularly attractive option if the 2027 Corvette does not come to Australia, as buyers can simply return the car and explore other options.
Finally, potential buyers should research international shipping options. While this may not be the easiest option, it is possible to import a Corvette from another country, although this will involve additional costs and complexities.
Cost Breakdown / Pricing Impact
While specific pricing has not been announced, the 2027 Corvette Grand Sport is expected to be more expensive than the current Stingray. However, when compared to other high-performance sports cars, the Grand Sport offers excellent value for money.
For those who opt for the performance packages, the cost breakdown will increase significantly. The Z52 Performance Package will add to the overall price, as will the Z52 Track Performance Package. However, these upgrades are necessary for those who want to get the most out of the Grand Sport’s performance.
Mistakes to Avoid That Could Cost You Money
When considering a high-performance sports car like the 2027 Corvette, there are several mistakes that potential buyers should avoid.
One mistake is to buy the wrong model. If you are primarily interested in performance, you should opt for the Grand Sport or the Z06. If you are looking for a comfortable daily driver, the standard Stingray may be a better option.
Another mistake is to overspend on unnecessary options. While some options are essential for performance, others are purely cosmetic and can add to the overall cost. Buyers should be mindful of their budget and only choose the options that they truly need.
Finally, potential buyers should be aware of the cost of insurance. High-performance sports cars are expensive to insure, and buyers should factor this into their budget.
