The ZR1's Twin-Turbo LT7
The ZR1 shares its architecture with the naturally aspirated Z06's LT6 but adds twin turbochargers, resulting in the LT7 engine that produces 1,064 horsepower at 7,000 rpm and 828 lb-ft of torque at 6,000 rpm.
How Far Ahead It Is of the Rest
The next most powerful C8, the naturally aspirated Z06, produces 670 horsepower — meaning the ZR1 delivers nearly 400 additional horsepower over the next trim in the lineup, a genuinely massive gap within a single model range.
What That Power Translates To
The ZR1 has demonstrated a top speed of 233 mph in testing without the ZTK downforce package, cementing its position as the fastest Corvette ever produced by a wide margin.
Is the ZR1 Right for You?
The ZR1 is aimed squarely at buyers chasing outright performance numbers and track capability; for most owners prioritizing everyday usability and value, the Stingray or Z06 deliver excellent performance at a considerably lower price point.

Frequently Asked Questions
Is the ZR1 the fastest Corvette ever made in every metric?
By horsepower and top speed, yes — it's the outright fastest and most powerful Corvette ever built, though specific track lap times can vary by course and conditions.
How much more expensive is the ZR1 than the Z06?
Pricing varies by model year and options, so it's worth checking current MSRP directly, though the ZR1 commands a significant premium given its dramatically higher performance ceiling.
Does the ZR1 come with the same warranty as other C8 trims?
Warranty terms are generally consistent across the C8 lineup, though it's worth confirming any performance-specific coverage details directly with your dealer.
Is the ZR1 practical as a daily driver?
It can be, given the C8's genuinely usable everyday ergonomics across all trims, though its extreme performance capability is arguably underutilized in typical daily driving compared to track use.
