GM Parts Catalog Hints at Possible Corvette ZR1 Engine

The GM Parts catalog may have revealed details about the engine for the upcoming Corvette ZR1, as reported by Motor1.

 

  • An “LT7” eight-cylinder, 5.5-liter gasoline engine is listed in the GM Parts catalog.

  • The LT7 engine features direct injection, variable valve timing, and possibly excludes active fuel management.

  • The Corvette ZR1 is anticipated to debut next year, with pricing expected to surpass the Z06’s starting price.


 

Motor1 has recently shed light on the potential powertrain for the eagerly awaited Corvette ZR1. The clue comes from the GM Parts catalog where an engine labeled “LT7” was found. This engine is described as an eight-cylinder gasoline powertrain with a displacement of 5.5 liters. The specifications also mention features like “DI” (direct injection) and “VVT” (variable valve timing).

Interestingly, while “AFM” (active fuel management) is noted, there are speculations that it might not be incorporated into the Corvette ZR1. This speculation is strengthened by the fact that its predecessor, the LT6, lacks cylinder deactivation technology, and sources suggest that the LT7 might continue in this vein. Furthermore, it remains uncertain whether the LT7 will utilize the Z06’s flat-plane crankshaft.

Adding to the intrigue, there are rumors that the inclusion of twin turbochargers could boost the LT7’s performance, potentially elevating its output to an impressive 850 hp and 825 lb-ft. This could make it the most potent Corvette to date. However, Chevrolet might have grander plans.

Reports from 2021 suggest that Chevy is contemplating the launch of a more formidable Zora variant, which could be equipped with a twin-turbo hybrid V8 engine capable of delivering a staggering 1,000 hp and 975 lb-ft. Moreover, Chevrolet has already confirmed plans for a fully electric Corvette, indicating a promising trajectory for this iconic American supercar.

To round off, while the Corvette ZR1 remains under wraps, it is projected to be unveiled next year as a 2025 model. When it comes to pricing, it’s anticipated to carry a price tag considerably higher than its sibling, the Z06, which starts at $112,700 USD for the 2024 model year.
