Previously rumored for the 2024 model year, the ZR1 is now expected for 2025 or 2026, according to Muscle Cars & Trucks. Approximately 850 horsepower are rumored, which isn’t wishful thinking if you remember that the LT6 in the Z06 cranks out 670 ponies at 8,400 revolutions per minute.
Referred to as the LT7, the force-fed mill should be a torque monster as well. The LT6 makes do with 460 pound-feet (624 Nm) at 6,300 revolutions per minute, as in fewer pound-feet than the Stingray’s LT2 small-block V8.
Torque estimates range from wild to really wild, as in circa 825 pound-feet (1,119 Nm). Sensible pants on, even 600 pound-feet (813 Nm) would be more than adequate if you remember that the McLaren 765LT makes 590 pound-feet (800 Nm) at 5,500 rpm from a displacement of 4.0 liters. The more realistic of the two guesstimates would make the ZR1 a genuine alternative to thoroughbred supercars like the aforementioned special-edition Macca.
As for pricing, well, it’s nearly impossible to make an educated guess with the limited amount of information we currently have. For reference, the previous-generation ZR1 used to retail at $122,095 for the 2019 model year, including $1,095 for the delivery fee and $2,100 for the gas-guzzler tax.
