Earlier this month GM announced it was scrapping development of a new V8 engine for Cadillac. At the time, GM did not disclose a reason for the move. But at the Detroit auto show this week, CEO Rick Wagoner confirmed the U.S. government’s new 35 mpg CAFE standard is the sole cause.
The cancellation of a successor to the Northstar engine family was “the direct result of the 35-mpg fuel legislation,” Wagoner told Car and Driver magazine.
He said when the project was first started, his company had “more optimism” about the future of V8 engines and the effect of emissions and fuel economy regulations. As it turns out, GM’s wishful thinking wasn’t enough to prevent controversial law from claiming one of its first victims.
The move also raises questions about the future of fuel-thirsty engines in general — not only at GM but at other automakers as well. Ford, for examples, is putting an increased focus on turbocharged V6s. Even BMW is moving to turbocharging as a means of decreasing displacement. Some American luxury cars are already debuting as V6-only — take the new Cadillac CTS and Lincoln MKS as examples.
Because CAFE standards look at the overall fuel economy average for an entire company, low-volume high-performance vehicles are unlikely to be affected by CAFE. As for everything else, we could be witnessing the beginning of a trend away from large engines all together.

If Porsche started hybrid production, I see no reason Caddy can not do the same. And if performance of hybrid system is good enough for Porsche, it may be good enough for Caddy.
Unless someone expects Caddy (any Caddy) to outperform Porsche.

Good! We don’t need no stinking V8!!
Go with what Ford’s doing now, creating a twin-turbo V6 with 400 hp with a performace of a V8, but better fuel economy. “Eco-Boost”, hello GM????

Anything that is “special” edition (V-series, ZR1, Z06,) A car that maybe won’t see anything over 10,000 units a year won’t be affected so V8’s won’t die they just will be limited in what they are put in. And hey if Caddy can squeeze 306hp out of a 3.6 V6 with no boost and on 87 octane gas I would go that route over a V8.

I also think boost is the answer… Slapped a blower on my buddies 93 mustang and he would get 25-26mpg on the freeway…about 5 mpg better then what it got stock.

Well, as odd as it may seem, their OHV engines are plenty powerful, compact, and can be surprisingly efficient in a light, aerodynamic package. (like the Vette) Sure it doesn’t have the complexity and panache of a DOHC, but who cares? Because of CAFE, all automakers are going to have to drastically trim weight and improve aero anyway, so putting the “small block” in a top line model would still be a great performer, and efficient enough not to really kill their CAFE #’s. I think if they make their next-gen platforms 1000lb lighter, they could eek out 30mpg hwy/ 25 combined with a 400hp engine and their rumored 8sp tranny. The C6 Vette at over 3k lbs, already comes pretty close to that when driven normally. Heck, I got 32mpg in a C5 driving from LA to PHX once, and not always at the speed limit either, and it only had the 4sp auto. It wasn’t as good around town, but it wasn’t terrible either, prolly in the low 20’s mixed.

You need to ask yourself whether 300+ HP V6’s are sufficient, and I bet the answer would be unless you do track time, it would be more than good enough for any public street application in US. Porsche doesn’t have the most HP but its combination of handling and speed is a charm. Audi TT-S is of the same philosophy making it a cheaper alternative to the Cayman S.

I concur. The six does 0-60 in what, say, 6.5 seconds or so? I don’t think Caddy’s typical customer needs much more than that. Hell, I don’t need much more than that. I’ve asked before though, and I still can’t figure it out- GM seems completely occupied with this CAFE reg, while BMW, for example, which doesn’t sell anything remotely economical (MINI doesn’t count toward they’re CAFE regs) and comes out with a new V8 seemingly every 3 days, hasn’t shown any concern. It’s weird..

CAFE rivals the stupidity of No Child Left Behind. This is a bunch of crap and really does only hurt the American auto industry. What the government SHOULD be emphasizing is what comes out of the tailpipes. MPG’s are not the sole cause of global warming, emissions are. When the V6 out of the accord can put out 268hp and still get a ULEV-2/PZEV CARB emissions rating, you have a car that may not get great gas mileage, and certainly would not live up to CAFE standards in an entire fleet, but puts out less global-warming-inducing gases than many cars with smaller engines and better fuel economy. Restrictions on how much gas is used is not going to solve global warming, but a setup much like the one in Europe, focusing on parts-per-million, rather than fuel economy, is a much smarter and much more logical, not to mention friendly setup.

Scrappin the V8? That’s bs.. Look at BMW.. They won’t even scrap their V12s and I bet they won’t have a problem with fuel economy.. It’s just a matter of technology. A V8 can be just as fuel efficient as a V6 if the company designs it right.

‘A4′, what hurts the American auto industry is the American auto industry … no significant change in fuel economy in decades. And if CAFE never existed, where do you think these cry babies would be now? You’d be the first to blame a consumer who is in debt because he didn’t save money (ironically, many Americans) and now can’t afford to spend anything in bad times, but you’re just as quick to not blame the auto industry by not investing in its future through R&D. Be fair.
CAFE is more about energy policy than emissions regulation … so your analysis is moot. Not to say that emissions don’t or shouldn’t matter, only that depending on foreigners for oil imports at ever-increasing prices is a problem. At some point in the future, switching over to Europe’s practice may be an option.
For the ignorant monkeys here, educate yourselves before you fill these threads with your usual fecal matter.

So let’s say you’ve got a choice of 2 engines for your next car: both are 3.5l in displacement and both get 30 mpg highway. The only difference is one’s a V6 and one’s a V8. Which one are you going to pick? Am I just running off 8% Canadian beer fumes here or is it really this simple? V8s are an inherently better design than V6s, so just make them smaller! Granted 8 cyl costs more to make than 6, but if I’m buying a Cadillac…

Well, the US manufacturers are obsessed with fuel-guzzling V8s, and many of them would have a hard job finding an American designer competent at developing an OHC or DOHC engine under 2 litres. Engine size does not mean higher performance, (as for instance, any Porche owner will comprehensively prove) although it does have to be said it is amazing they have managed to squeeze huge amounts of power out of relatively antiquated engine designs.
The Dodge Viper’s V10 engine is indeed a considerable advance, but then the British car manufacturer Bristol, using the same power plant, has shown that the highest performance version of the Dodge Viper, is a pretty feeble thing compared to the Bristol FighterT which extracts over 1000bhp and 1000 ft/lb of torque from the same powerplant.
( http://www.bristolcars.co.uk/BristolFighter.htm ) Having said that, there is also an immense price difference between the Viper and the Fighter T!!!

Although I realize they have to meet the CAFE standards, I still think it’s a shame that GM isn’t going to have any OHC V8’s. I realize that the LS V8’s are really good, but a high-revving, low-displacement, direct-injected V8 would have been sweet.
I also agree with johnnycanuck. Why don’t they just try to make a very low-displacement (under 4 liters) OHC V8 with all of their fuel saving technology… direct-injection, VVT, cylinder shutoff, etc.

Good. Anyone against the (reasonable) reduction of emissions and consumption of fossil fuels is a selfish ass.
There’s nothing wrong with V6s, and with boost they can easily deliver the performance of a V8. Now if they were asking us to drive 4-cylinders…that’d be another story.

Considering GM makes more power than the Northstar engine with their 3.6L DOHC V6, I’m not particularly concerned. A DOHC V8 isn’t all that important when you have V6s that are perfectly adequate at propelling even larger cars and crossovers at a decent pace.
Besides, GM has proven time and time again that you don’t need to abandon OHV to make a world-class V8 engine. Cadillac can draw on that if they need a V8.

Big mistake, IMO. BMW will have V-8’s, Mercedes will have V-8’s, Infiniti will have V-8’s, even Lexus will have V-8’s, and Cadillac will have only V-6s? If that’s the case, they will go the way of Lincoln – down the tubes.
V-8’s can be made to be fuel efficient, and besides, you’re never going to make ground on CAFE numbers with your luxury models anyway. Focus on improving the MPG’s on your mainstream and economy models – don’t handicap your luxury models when your competition is ready to eat your lunch.

BMW doesn’t meet the current 27.5 mpg CAFE standards. They just pay the fines and pass the cost onto the consumer. They will continue to do so under the 35 mpg CAFE standards. They can afford to do this because they are a luxury brand and can charge higher prices. GM, however can not do the same because they don’t have the same prestige.

Okay point taken. But GM isn’t a single company with one brand image. Cadillac has a different one than Saturn for example, just as Bentley and Volkswagen are not mixed up.
So if they put some effort into making Cadillac a luxury brand again, they can pass the cost on, too. Right now they are shooting themselves in the leg.
I personally only consider companies that have V12s in their lineup as luxury, so basically Mercedes, BMW and Audi, and of course the small companies like Maserati or Aston Martin.
So Cadillac with only V6s? That means that no Cadillac will have more cylinders than a top-range BMW 1-series. Come on.
And plus: Europe will have much harder regulations to face (130g of CO2/100 km = 37 mpg for gas and 42 mpg for diesel engines..)
And I’ll bet any amount of money and my genitals that none of the mentioned manufacturers will give up V8s or even V10s and V12s.
With a camless engine all those worries shoulkd be forgotten.. and if Fiat is developing one, Cadillac definetely should be able to afford it.

I agree with you that GM could pass the cost along to consumers by charging more for Cadillacs. GM is probably in panic mode right about now and is looking to improve mpg in anyway that they can. There will still be V8 Cadillacs, just less of them, and probably at a higher price.
Another reason BMW can get away with simply paying the fines is because they are a small company and very profitable as it is. They can afford to pay CAFE fines based on production volume.
GM is such a large company that it can’t afford to pay big CAFE fines. They could make Cadillac as fuel inefficient as they want, but they would be forced to work even harder to make up the mpg difference in their other lines with cars that get even higher mpg.
I see two types of cars becoming more common in the near term. Inexpensive, slow, low displacement subcompacts and cars that can “afford” to be a little quicker in the 0-60 because they are loaded with expensive technology be it hybrid, diesel, etc.

I guess GM can no longer put a ridulously tall 6th gear in its V8 cars so they can claim 26mpg. GM doesn’t know how to build effecient V8’s Thats why I laugh at people who brag about the great economy of the vette. It drinks gas in every gear, guzzles it when you press the throttle. I guess the government will no longer allow GM to cheat this way with misleading claims of great highway fuel economy.

The move to cancel the V8 for a standard engine option does not bother me. As is the new direct injection V6 is making good power, almost as much as the V8 Northstar does now. Add turbocharging to this and there is plenty of power on tap for all but the most hardcore. For them there is the V series anyway. Some great fuel saving technologies have surfaced in the past few years that have allowed us to still have the power we demand while increasing fuel economy. Ain’t it cool.

I also wonder how they are going to count the plug in hybrids such as the Volt. That should give GM a little wiggle room for their truck and luxury car division.
Also, GM is working hard to present itself as a greener company as that is starting to sell with the advent of $4 a gallon gas. If higher milage wasn’t in GMs pocketbook’s best interest they wouldn’t be doing it.

G: The auto industry is already moving away from fossil fuels whether CAFE is the reason or not. Most likely because of the cost of energy than the resulting emissions. But, what would you rather have?.. a new V8 from Cadillac (which you can count on being more efficient) or Toyota making a killing selling more Prius than ever before? We all know about the Prius’s production emissions.
So, GM doesn’t get their V8 for Cadillac but you have Kia moving introducing a V8 into market.
