2018 Chevrolet Corvette ZR1 spotted at Nurburgring, DOHC LT5 Questions Abound!
2018 ZR1 is coming, will the DOHC LT5 V8 engine make it’s debut?
A dual-overhead cam V8 engine, dubbed LT5, is coming. Manufacturers file patents all the time, some fall through, and others come to fruition. However, this is a bit different, as it’s an entire engine. GM isn’t going to publicly disclose a storied name like LT5 by coincidence. Of course, LT5 was the 32-valve, DOHC V8 engine as used in the C4 ZR1, a technological powerhouse and world-beating sports car.
Additionally, we know that Chevrolet has been testing a hardcore, extreme track-focused C7 Corvette. Track day junkies have bemoaned that the current Corvette Z06 doesn’t really work on track. The chief issue being overheating, an inherent issue with supercharged engines on track. It makes sense that GM would prepare a response to owners disheartened, who are looking for more.
So, what constitutes more? In this case, it looks like a substantially more aggressive aero package and the aforementioned LT5 engine. Did we mention the aggressive aero? That wing and splitter setup would shame some Trans Am cars.
More volume also seems to be the name of the game. In this latest spy video, which captures the ZR1 on the Nurburgring, the mega ‘Vette is insanely loud. The sound is of particular interest, because at least to my ears, it doesn’t sound like a typical uncorked small block Chevy V8. Perhaps I am hearing more than is there, but it also sounds like some serious RPM is coming from the engine. Even the mighty LS7 could only spin to 7,000RPM. Of course, push rod motors can be built to spin, NASCAR guys sit at 9,000RPM all day. However, this may be another hint that points towards the DOHC LT5 being a reality.
