Feature Spotlight: The 2019 C7 Corvette ZR1’s 6.2L LT5 V8 Engine11
No, the 2019 C7 Corvette ZR1 does not feature a DOHC V8 engine as once rumored, though it’s unclear where such plans stand at GM. That’s a different discussion.
Instead, Chevrolet revealed the most powerful Corvette ever with a 6.2-liter supercharged LT5 V8 engine, which invokes the original C4 Corvette ZR-1‘s DOHC V8 engine. The destination returns only in name, not in packaging. But, what makes the LT5 different from the LT4? Two major things.
Foremost, the 6.2-liter LT5 V8 features a larger supercharger with 52 percent greater displacement over the LT4 V8’s supercharger. More boost means more power, and the 2019 Corvette ZR1 isn’t short on horsepower at 755 hp. Secondly, GM’s first-ever dual-fuel-injection system surfaces with the new LT5 V8 engine. The system employs direct injection as a primary and port injection as a supplementary method.
We’ll have to wait for the full debrief on the LT5 engine, but it’s certainly not just an LT4 by another name.

will dual injection make it into the 2019 Silverado? it could be a good sign that it will. the 2019 Silverado with DSF and dual injection could top 480tq and include a 20% efficiency boost. That would be a beast of an engine. I only hope they offer it in the mid trim silverados and gmcs
I believe its the future for all engines, the secondary primary use to clean deposits off valve and intake port. Ever tear apart a direct injection engine after 50k miles, half the port is coked up to the point if feels like part of the casting. Subaru BRZ/86/FRS motors have this same injection system for the same reason. Again another domestic automaker spouting off they are first production motor with secondary injection, much like ford first mass production flat plane crank which is what every Porsche and Subaru motor is.
Toyota figured out the secondary injection trick more than 10 years ago.
Truth hurts I guess for the fanatics. Every Lexus with Di has had it for years.
No one has it on a OHV engine’s but gm. DOHC engines yes.
This gives me serious hope for the 2019 Camaro SS, ZL1 & Z/28. I’m quite sure GM will introduce this into the whole V8 lineup along with the truck lineup. I’m psyched for what is coming to the high performance V8 world!!! This is awesome!!!!!!!!!
Gm’s new DOHC V8’s is coming to :: TT V8’s DI and Port injection (4.2-liter and 5.5-liter).
C7 Corvette Chief Engineer Tadge Juechter said that a DOHC-4v engine is very wide and tall; this is why it’s possible to slip the LT1 and LT4 into any GM car that uses the 3.6L DOHC-4v V6; if the C8 Corvette features an engine with a DOHC-4v configuration, it will mean this new engine will be exclusive to the mid-engine C8 Corvette because it will be too big to fit in any current production vehicle.
Walter Rohrl, rally ace and general Porsche legend says modern supercars are getting too fast for the Nurburgring.
He goes on to say that the current production car record holder. The 911 GT2 produces up to 416kg of downforce, way more than most supercars. That’s 917.123 lbs.
The C7 ZR1 is said to produce about 950 lbs. of downforce, This is starting to sound interesting.
I dont see this happening (too crazy to have a 750hp Caddy perhaps?) but not only would i LOVE to see what the current ctsv could achieve with this dropped in but i’m curious if some of the powertrain engineers at GM/Cadillac arent toying with the idea of dropping this in one for the hell of it to see the results. The LT4 isnt a slouch by any means but in terms of packaging i dont THINK there would be a problem fitting this is the current ctsv’s engine bay since the only differences in dimensions are the height because of the blower, but modify the area in the hood where the vents are a bit and i dont see why the appropriate clearance cant be achieved. OR they could give the ctsv’s hood the treatment they did for this new vette and just let the blower stick out loud, proud, and beautiful with the carbon/vents surrounding it. They put the LT4 in the Z06 AND CTSV…now that they’ve come out with this new monster in the ZR1 now all there’s left to do is just drop this in a special-edition limited production ctsv! I’m not sick of or bored with the current ctsv, but you cant tell me dropping this new monster in one isnt a compelling frigen idea! It only seems right, and it makes complete sense to me! C’mon, someone at GM make this happen!
Why would you put a dime in a car that doesn’t sell. Sedans are dead.
