Is It For The Corvette ZR1?"},"content":{"rendered":"<p>A lot of digital ink has been used to write rumors pertaining to what sort of engine the hotly anticipated Corvette ZR1 is going to use. We finally might have a good understating of the powertrain in question thanks to an item included in the GM Parts catalog discovered by the folks at the <em>Mid Engine Corvette Forum<\/em>. As seen in the screenshot below, an &#8220;LT7&#8221; is listed as an eight-cylinder gasoline engine with a 5.5-liter displacement.<\/p>\n<p>Deciphering the subsequent acronyms is quite easy as &#8220;DI&#8221; stands for direct injection while &#8220;VVT&#8221; is variable valve timing. As for &#8220;AFM,&#8221; it means active fuel management, but it&#8217;s apparently not planned for the Corvette ZR1 despite being listed in the GM Parts catalog. The LT6 doesn&#8217;t have cylinder deactivation tech, and insiders claim the LT7 is unlikely to add it. The leak still doesn&#8217;t confirm whether the engine is getting the Z06&#8217;s flat-plane crankshaft or not.<\/p>\n<p>Equally interesting is the &#8220;M1K&#8221; codename for the gearbox, which is different than the &#8220;M1M&#8221; used by the Z06, the &#8220;M1L&#8221; of the regular Stingray, and the &#8220;MLH&#8221; installed in the E-Ray. Given the extra oomph provided by forced induction, one can presume &#8220;M1K&#8221; is a beefier transmission able to cope with the additional power.<\/p>\n<p>Adding a pair of turbos is rumored to increase output to 850 hp and 825 lb-ft to create the most powerful Corvette ever. However, its status as the beefiest variant could be short-lived since Chevy is allegedly planning an even hotter Zora with a twin-turbo hybrid V8 producing as much as 1,000 hp and 975 lb-ft, according to a <em>Hagery<\/em> report from early 2021. Add into the mix the already-confirmed fully electric Corvette, and the future looks bright for the American supercar.<\/p>\n<p>Meanwhile, the Corvette ZR1 is expected to land next year as a 2025MY and command a significant premium over the Z06, which kicks off at $112,700 for the 2024MY.<\/p>\n<p>Source: <a href=\"https:\/\/www.motor1.com\/news\/693988\/lt7-turbo-engine-gm-parts-catalog\/\" target=\"_blank\" rel=\"noopener\">Read Full Article<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A lot of digital ink has been used to write rumors pertaining to what sort of engine the hotly anticipated<\/p>\n","protected":false},"author":2,"featured_media":243647,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v21.8 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>LT7 Turbo Engine Appears in GM Parts Catalog.
