Jfjr, there is no actual legitimate reason to put the ttv6 in the ats-v.
You could argue fuel economy but you'd just be kidding yourself. Look at the f150 with the ecoboost v6. Truth is, the only benefit to the v6 is that you can say you have a v6 and sound Eco friendly.
Totally untrue. The main advantage of the ecoboost v6 isn't in the window sticker or "real world mpg" to its users - it is
actually what the CAFE numbers are. Due to variations in testing for the EPA and DOT testing (Window Sticker and CAFE) manufacturers now have to calibrate a powertrain for one method or the other (or somewhere in the middle). In the case of replacing a V8 with a TTV6 (where the CAFE testing leaves the engine
entirely out of boost, it blows the V8 out of the water something fierce. GM putting the TTV6 in the ATS/CTS/XTS helps to allow the vehicles to do better on CAFE, which allow boosted V8s through without killing the entire curve. It's dumb that the government has multiple ways to test the same thing and multiple departments to do it - but it's been that way for decades.
You could argue weight but you wouldn't actually be basing that on hard facts at this point. You'd just be speculating and the truth is, with the small block being a smaller engine dimensionally than the DOHC v6, plus the LT1's lack of forced induction hardware, the weight of the engines will be very similar.
From what I've heard (for a year) it's not the total weight - I'd wager good money the TTV6 with intercoolers and all hardware will be slightly
heavier than the LT1 - but the center of mass will be several inches closer to the firewall and
apparently if you were interested in maximizing steering feel and handling performance, that makes a big difference.
You could say that the car will do 60 in 4 seconds, but I guarantee the m3 will do it sooner.
If you're going to accuse others of speculation about engine weights, you gotta admit your comment about a "guarantee" of under 4 seconds is speculation as well. We know the fastest times won't be with manual transmissions now, but that's about it. The first big hurdle is the addition of Euro6 emission standards on the M3 - the penalty it hits having to hit those standards will also apply to the US, which is something that Cadillac actually doesn't have to deal with. Second, any car that
can hit a 0-60 about 4 seconds or faster with only 2WD starts to become increasingly inconsistent on the street to hit that time - I suspect BMW will be slightly
conservative with the car's 0-60 and set up the car to be
consistent instead of just balls-to-the-wall fast. The last M3 and 335i are actually really close in 0-60 despite all the advantages the M3 had. The new one isn't adding
that much to the table.
The new e63 does 60 in 3.3 seconds.
There is no "New E63". Lets be specific here. The new E63 AMG hits it in 3.4 seconds (rated). It also has AWD, which is how it hits those numbers. Second, the E63 AMG
starts at $93,000 - which is in the stratosphere compared to the second gen CTS-V at $65,000.
That said, you do hit a good talking point that doesn't belong in this thread, but is valid. Should GM really "kick up" the CTS-V's price from one generation to the next by $25,000? Does GM
really push the CTS-V that high? Or would it make more sense in some strange way to have a "CTS-V+" sitting above it, much like an "AMG Black"?
The new ctsv needs to be no slower than 3.5.
In order to get to 60 that fast consistently, it'll need AWD, which is a whole new direction for the CTS-V.
Oh and if the 7 speed isn't put in the atsv, Cadillac will really have missed the boat.
Agreed 110% - I hope it fits. The next question becomes will they eventually offer the 7 speed manual with the TTV6 in the CTSV-Sport? GM has this habit of having the same engine in different cars on the same platform with different transmissions, and it needs to stop. The Germans are getting away from manual transmissions these days and I think it would bring GM credit to offer them - even at a price premium - in as many vehicles as possible. Just take the hit in engineering for the street credit you gain.
