2025 Chevy Corvette C8 Horsepower: Every Trim Compared
The 2025 C8 lineup spans an unusually wide performance range, from the naturally aspirated Stingray all the way to the twin-turbo ZR1 — four distinct engine philosophies under one nameplate.
Stingray
The base Stingray uses a naturally aspirated 6.2L LT2 V8 producing 490 horsepower, or 495 horsepower when equipped with the optional performance exhaust, along with 465 lb-ft of torque — the most accessible entry point into C8 ownership.
E-Ray
The E-Ray pairs that same Stingray-based 495-hp V8 with a 160-hp front electric motor and a 1.9-kWh battery, adding all-wheel drive and a combined output of 655 horsepower. It's the quickest-accelerating C8 for the money, capable of reaching 60 mph in roughly 2.5 seconds.
Z06
The Z06 uses a completely different, purpose-built naturally aspirated 5.5L LT6 V8 that revs to a much higher redline than the Stingray's engine, producing 670 horsepower at 8,400 rpm and 460 lb-ft of torque at 6,300 rpm.
ZR1
The range-topping ZR1 uses a twin-turbocharged version of the Z06's architecture, the 5.5L LT7, producing a claimed 1,064 horsepower at 7,000 rpm and 828 lb-ft of torque at 6,000 rpm — making it the most powerful production Corvette ever built.

Frequently Asked Questions
Which C8 trim has the best power-to-price ratio?
The Stingray offers the most accessible entry point with genuinely strong performance for its price, while the Z06 delivers a significant power jump for owners prioritizing higher-revving, naturally aspirated performance.
Is the E-Ray faster than the Z06 in a straight line?
The E-Ray's combined power and all-wheel-drive traction give it an edge in straight-line acceleration to 60 mph, while the Z06's higher-revving engine and higher total output favor it in extended high-speed performance and track scenarios.
Why does the Z06 use a completely different engine than the Stingray?
The Z06's LT6 is purpose-built for high-RPM performance with a flat-plane crankshaft design borrowed from motorsport applications, allowing it to rev significantly higher than the Stingray's more traditional cross-plane V8.
Is the ZR1 available with all the same options as other trims?
Trim-specific packages and options vary, so it's worth checking current model year availability directly with a dealer for the ZR1's specific configuration options.
