Love the little video clip. Awesome!

I am guessing Gen V will be in the corvette in 2012 Model year and in the camaro in 2013 Model year.

BMW has had it for years, and it is on the Nissan 3.7L VQ V6.

The 3.7L has a cam though doesnt it? I swear to god it does. And thank you Captain Awesome!

Hmm... Maybe it was BMW then. I couldn't tell ha' because the article was in GMHTP but they didn't report on what company it was. Learn something new everyday

It is? I've never seen any mention of it.

The VQs have 4 cams that are all driven by the crankshaft. Their new thing is an electric motor that varies intake lift so it can cruise with the throttle wide open for higher efficiency and better "throttle" response.

I think that their variable compression is a much cooler initiative. When the turbo(s) spool up the compression can drop to allow higher boost, but it can run higher compression at low loads for higher mileage and lower emissions.

BMW's do have Cams with "Vanos"

I'm very interested in the Gen 5 V8's. If they're the same displacement with more power and fuel efficiency I'll be very happy. However, with the push for fuel economy so high, I expect the power level to be the same with smaller displacement and much better fuel economy. If that's the case, I don't know if I'd rather have the LS3 for displacement, or the Gen 5 for its DI advantages.

If it was the same power/torque, would it really matter that much what the displacement is? The way I look at it is, we can't keep increasing displacement...at some point it becomes excessive, and somethings gotta 'give'. A nice 5.3L or 5.7L ~400hp/tq engine and 26mpg (in a Camaro or G8 sized vehicle) would be great, imo.

I tend to agree with you, and besides, the LSX and other crate engines are always going to be out there for those "special" occasions.

hmmmm...... I like the sound of a Generation 5 HEMI V8, I hope SRT will based it off the new Phoenix platform, and not a LS based engine they found out of a junk yard lol

LOL! It's so strange how close the HEMI looks, block-wise. I don't understand why they continued to use iron blocks though, particularly with the 6.1s. It's my understanding the cylinder walls could be considered a liability, somewhat, and the pistons ring pack thin, but I think the bores are close to the same as LS3/L92 so why not aluminum?

The 6.1 is somewhat unique lets see I mean redline of 6400, large engine, forged pistons, beefer rods, forged crank, bigger valves bigger cam etc. i think same applies on it too. More like 450-460 hp at the crank .... I don't know why they use iron blocks.....for the torque?....

hmmm.....scratch that

Actually the pistons are still hyper-eutectic (cast) on the 6.1, the rods are powdered metal like the 5.7 but slightly heavier, the valves are now the same size (2009 5.7 went from 2.00in. to 2.05 same as the 6.1L), the compression ratio on the 5.7 is actually slightly higher now (10.5 versus 10.3) and the heads flow as well as or better than the 6.1 head. The cam lift is still higher, but that can be changed. The gap between the engines has gotten a lot smaller than it was a few years ago. The 6.1 really is due for an update.

BTW for those who want a challenger really go for the R/T........its way more mod friendly, cheaper than the SRT and its underrated......because dodge did not want the R/T to compete with the SRT8..... HP is really north of 390 and north of 400 torque
