Cadillac's President Reminds Us A New Cadillac V8 Is Coming

This is good news, there need to be more V8s.  But 2-3 more years wait?  I guess the problem goes back to not keeping the V8s going in the 2009-2015 time frame.  So it is back to square one.

Hopefully a V12 is to follow, but no business case would exist for one, so they won't do it, even though they should.

BMW and MB will be forced to kill their V12, Europe is pushing to pass even more stringent standards on engines and technology is already showing that the days of the V12 are very limited. V8 will be the new V12.

Maybe they've dusted off the UV8 that was supposed to replace the Northstar? I was under the impression it was fairly far along. 

My impression is that this is an all new engine.

Maybe a V8 based off the new V6 the CT6 is getting? 

Mercedes will never kill that V12, they just redid the 5.5 liter V12 to a new 6.0 liter V12 for 2015 model year, and the plan is to keep it going. BMW won't drop the V12 because they need it for Rolls Royce. Those two brand have enough hybrids and diesels and the Mercedes V12 has start/stop on it to curb emissions.

With the Maybach variant coming along w the Pullman I don't see the V12 going anywhere at MB..

A V-12 didn't save the first maybach revival...

A V-12 didn't save the first maybach revival...

It ran for over a decade...and this one is just a stretched S-class, so the investment can't be much..

The Mercedes V12 is Bin5 ULEV III 125 emissions rating so it meets California emissions for 2025.   The S600 scores a 6 on a scale of 1-10 with 10 being an all electric, zero emission car, a CTS also scores a 6 in smog rating.    The V12 will be around a while.

will it be a normally aspirated L86 type high-torque normally aspirated V8 though

I'd think twin turbo 4.0 liter.  If they have a 2.0 liter turbo four and a 3.0 liter turbo 6, it only makes sense.

I would expect their own engines fully new and not some rehash of some outdated still born design.
 

Based on what the engineers are finding I would expect a 4.0 TT V8, 3.0 TT V6 and 2.0 Turbo.  No V12

SMK you need to get a grip that it takes more than 2-3 years to build, design and build 3 engines not really due in cars set for 2020 and later. This is not just some rehash of a head gasket blowing N Star.

The fact is for that they intend to do is amazing in todays market let alone for GM to be willing to do it. This will be something special as this kind of stuff just dose not get the full support in this kind of business climate.

The fact is that GM going along with the fact that they admit even if they have good cars today that they are still not good enough and allocate $12 to make them even better is amazing.
 

The key here is if GM can get these cars right they don't have to beat MB and BMW in sales but make high profits per unit to be successful. These cars if done right will generate profits in the area where trucks have been doing for years. It is not like a Malibu where you have to sell 150K units of each model as with low volumes only a third of that will generate profits 3-4 times a BU.
 

This is how this segment is being looked at and why GM is willing to put money. Cars like the 300 and Lincoln are not doing this as they are cheaper and then get further discounted from there. That is why price point at Cadillac is a priority. If they can't get the higher price for what they have now they will fix the cars, marketing and dealers to attain that goal.

I really have a gut feeling what we see in 2020 will be something we never though GM or Cadillac would ever do again. They will build a car that is a standard of the world in more than just slogan.

I think so too: maybe two 2.0L blocks paired?

Wouldn't that make it an inline 8?

I'd rather see two 3.0 v6 blocks paired for a V12.

A V12 should be considered if that configuration will still be used by European brands.

But the 4.0L V8 twin turbo speculation is the most reasonable.

Keep in mind that the Cadillac El Miraj had a 4.5 liter twin-turbo V8 that produced 500 horsepower and 500 lb-ft of torque. Seeing as the new 3.0TT can produce 400 hp and 400 lb-ft of torque (133 hp/l) the El Miraj's numbers seem about 100hp and 100 lb-ft soft.  

My take?  The horsepower number of the concept is the correct one, but Cadillac will do it with 4 liters instead of 4 and a half.

Oh God no. This is not the old GM where they will do cheap short cuts to save a buck.

The V8 will be a entire new engine and not stuff grafted together to save money.

The only reasons I say 2.0-3.0-4.0 is because with a turbo engines this size has been found to be the most efficient for power and economy. In the SAE story I read a while back they said these sizes were found to be the sweet spot and are why they are so common today.

God you made me think of that awful Quad 4 grafted V8 they did. At least it never went production and gave way to the N star that had its own issues with underfunded development.

Excuse me while I go wash my memory. LOL!

My bash on the N star is not as much design as it was on the quality of the build. The engine needed things like head studs vs. the cheap head bolts and it could have avoided many of the blown head gaskets in several of the years. Also the ring issue was never solved for the people who did not run them hard. Carbon build up lead to a lot of oil use issues. This was most problematic on Cadillac's owned by older people who never saw hard RPM. You often could take them and blow them out to fix it but many never knew to do that.

and in theory, you can use the same pistons from the 2.0 in the 3.0 and 4.0.

^ That's exactly what GMC & Electromotive did, mid 20th century.

That sounds like Ford's modular engine idea from the last 25 years...

LOL I meant paired as in basic specs like bore, stroke, cylinder wall thickness. not gluing a couple 2.0L engines together

It goes back s lot further than that.

I know but it brought back some bad visions of the past.

I could see this parts sharing on Chevy or other GM models but if you want exclusive engine you don't want to show a lot of parts sharing with a V8 with 4 cylinder pistons. While this is smart economically it is not smart in a higher class vehicle you are going to ask 2-3 times the price for. Sharing parts comes across as cheap cost savings in a class where you expect the engine to be well crafted for each and every vehicle.

In this segment they can afford to spend more as they are making a lot more profit per each unit.

Part of the problem Cadillac and many other GM car have had is they have shared too many drivetrain parts on models where it matters. Pontiac's heart and soul was their own engines and tunes. While the last TA models with Chevy engines were great cars they really were just rebodied Chevy models and really had little Pontiac DNA. IF they had not looked better than the Camaro they would have failed long ago.

Cadillac needs to make 3 distinct engines with tunes for each and every model they serve. The engines need to be a part of each model not just what ever they had that they could put under the hood.

Most consumers have no idea if what's under the hood is shared with other brands let alone care. I doubt if exclusive engines would help sales.

Yeah.. the only brand I can see really sharing any of Cadillac's engines would be Buick.. and only in the top-end if an Avenir type vehicle was built. I think even in that iteration it would be overkill to go the Enthusiast's route for what really should be GM's Lexus rival.
