据传通用将正式公布6.2升V8双顶置凸轮轴引擎。从正式文件看，这台被称为“LT5”的引擎是一台“6.2升SIDI,DOHC BBT,ALUM”引擎，仅提供给考维特车型。这也是LT5 V8引擎文件的第二次曝光，上次是在今年7月，当时通用赛车合作公司Katech在其网站上注明这台LT5引擎是C8考维特ZR1所搭载的引擎。现行版考维特搭载的是自然进气LT1和LT4机械增压引擎，这两台引擎仍将搭载于2018款车型上，而LT5则是第三台引擎，该引擎将配备在下一代C8中置引擎车型上，另外该引擎也是C7 ZR1的候选引擎。

 

Corvette's rumored 6.2-liter DOHC V8 surfaces in GM document leak

General Motors' rumored 6.2-liter dual-overhead cam V8 may have been confirmed in official paperwork.

 

An official service document, spotted by a Reddit user, listed a new 'LT5' engine with the description "6.2L, SIDI, DOHC, BBT, ALUM" alongside a code indicating it will be a Corvette exclusive, according to details posted by The Drive before the PDF was removed.

 

This is the second leak surrounding a resurrected LT5 V8. The first indication surfaced in July when GM racing partner Katech briefly had a website page titled "C8 Corvette ZR1/Zora LT5."

 

The Drive points out that the current Corvette's engines -- the naturally aspirated LT1 and supercharged LT4 -- are still listed in the model lineup for the 2018 model year. The LT5's presence as a third Corvette engine for 2018 is viewed as evidence that it will be arriving in the next-generation mid-engine C8, though the C7 ZL1 is also considered a potential candidate.
