Imposter LT5?

[Mr.Yuck]

I'm out at SEMA looking at the 6.2 liter LT5 in the ZR1 C7? I didn't know they offered the LT5 in a C7? You can buy it as a crate package with ECM for $20,000 on up. I didn't realize they called this overhead valve engine a LT5 ? it's supercharged it does have 16 injectors with direct injected keep in mind. 755 horsepower is pretty impressive. I'm mildly offended they're calling it the LT5.IMAG1588.jpegIMAG1589.jpegIMAG1590.jpegScreenshot_20181101-225744.jpeg

Wonder if it would fit in a C4/ZR-1
w/o a whole lot of backyard engineering?

The rest of us are pissed they defiled the LT5 name w an OHV, in block cam motor.

Why on earth does GM insist on reusing engine codes? What is the purpose of a code identifying an engine, if it's not unique to the particular engine?

Remember the ZL1 engine Corvette of which only 2 were produced. Now they have the ZL1 engined Camaro.

Remember the ZR-1 Corvette from the early 70’s. Now you have our C4 ZR-1 cars.

All marketing hype.

Zr-1 is a flagship model, like an M5 vs 540i or CL65 AMG vs CL600. Makes no sense to not continue using the brand name. None of them do however re-use motor codes. They might re-use a letter, like BMWs letter S in M-cars (S62B50 for example), but not an entire code.

Doesn't make sense to me. Doesn't the code identify the engine?? Not any more.

So I had lunch at SEMA today with a engineer from the NEW LT5 development branch and he said "it's marketing it's all about the marketing." He's had many bench racing Round Table meetings going back to 2015 involving long conversation with the GM brass about the dilution of the market with the use of the ZR1 and LT5 logos as he called it. He informed me they spend millions of dollars on Market Research, product Association and population Dynamics studies. That this is good for all parties because of the history of the LT5 success and performance which is a testament to our cars and we should hold on to them..... I thanked him for lunch and his time then I ended it with "I'm not buying what you're selling and it's a good sales pitch for an engineer but unless your NEW LT5 is a DOHC motor it's not a LT5." He nodded with acknowledgement smiled shook my hand and thanked me for my input..... I know it's not going to make a bit of difference but I felt it needed to be said.

I'm surprised they haven't used L88 yet. But GM can't help but reuse what they figure the public can identify with from the past. Why not? Hell the Chrysler Hemi isn't a true Hemi like the original. They sold the LS6 as a crate engine for many years. Then in 92 you had the LT1 come back. The Trans Am still used the WS6 package and Ram Air returned. It's kind of like when Hollywood does a remake of an old movie. Hey it sold before lets do a remake of this or that. Since I'm not up on Ford do they reuse designations like GM? Do they have a Cobra Jet or Super Cobra Jet?

You did the right The fact that they never acknowledged or touted the LT5 as the only production motor to ever go 5000mi in 24hrs? For Pete Sake.
