Just speculating, but could the new LT5 engine be a derivative of the recently released Mercury Racing 775hp DOHC SB4 engine???
The new GM LT5 is likely to hit the Chevrolet Corvette lineup in one of 3 ways - all of which will be appreciated by lovers of fast cars. Reprinted from TorqueNews.com with permission.
Yesterday we talked about the arrival of a new LT5 engine for the Chevrolet Corvette in the GM dealer service system and today, I bring you a look at how I am guessing GM could use this new engine – most likely in a new trimline or even the long-rumored mid-engine Corvette.
Based on information which has seemingly been removed from the General Motors dealer service computer system, there is a new LT5 engine coming soon and it will seemingly motivate some variety of the Chevrolet Corvette. It was originally expected that the LT5 would power the next generation Corvette ZR1, but with the simple details of the next LT5 making this mill a bit too mild for the ZR1 – it seems unlikely that this LT5 will be tucked under the hood of the mysterious, masked supercars caught testing around the US.
All that we really know from the GM dealer service listing is that the new LT5 will be naturally aspirated, it will be all-aluminum, it will feature direct injection, it will measure 6.2 liters and – most importantly – it will be a dual overhead camshaft engine. The last DOHC V8 used by GM was the previous LT5 in the C4 Corvette ZR1, but it is expected that the C8 ZR1 will offer more than 700 horsepower and 700hp from a naturally aspirated 6.2L V8 seems unlikely. Realistically, this engine is more likely to offer power in the range of 500-600 horsepower, and with less power than the LT4 in the Z06, there is a good chance that this will not be the ZR1 engine.
So, if the new LT5 isnt being used for the long-rumored Corvette ZR1, but it is earmarked for use in a Corvette in the computer system information, we are left guessing how this LT5 will fit into the Corvette lineup.
Why Things Happen in Auto Industry
I was told the same thing by a corvette performance shop that Mercury Racing had already developed a 700+ DOHC engine and GM was most likely going to use that engine in the ZR-1!
But of course we are all sitting on pins and needles for the release of this monster!
