What GM uses is outdated, they still use pushrods in this day and age....push rods. It is not rocket science why Japanese cars last longer...less parts. Mean a less likely chance of break down. GM knows this, but it costs too much (they say) to meet the standards of the world. Nissan, Toyota, BMW, and Mercedes and every other manufacturer in the world are more than happy to accomodate us with world standards.

Really? Longer lasting? I have a 1988 Buick Park Avenue with the 3.8 litre V-6 and a 1989 Cadillac Brougham with a 5.0 litre V-8. Both are pushrod engines. They're still here as are millions of older cars with pushrod engines. Most of the Japanese cars of the same vintage around here have collapsed into piles of iron oxide dust about five to ten years ago.
 
My 2002 Cadillac Seville STS had a DOHC Northstar V-8 and my current 2007 Cadillac DTS Performance has the same engine. To be brutally honest, I can't tell the difference between how well a OHC/DOHC engine performs versus a OHV design except that the pushrod engine has more of a punch with the torque. I miss that little "kick in the butt" with the OHC/DOHC designs.

If one counts the cam lob as one part and valve as a second part, then a DOHC engine with 4 valves per cylinder (the usual case), has eight valve train parts per cylinder and at least two, if not four cams per engine. The pushrod has the valve, lob and the pushrod and rocker arm for a total of four parts per valve. However, the pushrod engine has half as many valves per cylinder, so the total parts in the valve train are the same. But there is one one cam per engine, so a pushrod engine has fewer expensive parts.

Your STS's engine is tuned for high speed performance and does not have much low end torque. The 3800 is tuned for low end torque and has little power or torque at high engine speeds (over 5500 RPMs). My supercharged 95 Riviera and my 98 Aurora had very similar performance. My 2002 Seville, tuned for low end torque, was very similar to the Riviera for performance. The Riviera's supercharger made icy roads much more difficult to start up on.

Longer? by imidazol97

More reliable? I have 2 3800s in full-sized comfortable cars that get great gas mileage and don't cost me double for service in a foreign car store's service department for repair let alone piled on maintenance mandates from a dealer who sold me a totally reliable car but seems to think it needs constant over-servicing and replacements to keep it 100% perfect?
 
I'm not sure where this world commission is that determines what is out-dated and what is world standard choices. I want a car that has lots of torque and doesn't have to wind to 5000 rpm before high torque appears and then it's time to shift again...
 
As for Japanese cars don't break down--I have been collecting complaint posts asking for help with those Japanese brand cars failing their owners in my Watched Items page. I can link to some of them if lykourinou needs help finding them.
 
Sometimes I realize that people live in the past and think they can still hang problems of the 80s and 90s where a higher problem rate occured for some owners of US brand cars rather than stepping into the current world where JDPowers ratings show US built cars on a par with the Japanese brands. Things have changed in the build of US brand cars; and things have changed in those Japanese cars.
Does anyone have a link to the JDPowers ratings. I have to look through lots of bookmarks to find the last ones I saved and can't find it quickly.

I've driven my fair share of OHV engines over the years, and I didn't find the low-end torque to be a "kick in the butt" at anything less than WOT, and even then the "kick" didn't last long. I don't think that's a good trade for the loss of rpm range, horsepower, and smoother power delivery.

I think that it can be said that a well designed pushrod engine will last just as long as a well designed DOHC engine. I also think that in the case of a poorly designed DOHC engine, the cost of replacing it when it fails will probably be twice as much as a failed pushrod engine.

I Give UP by lykourinou

the 3 of you must work for GM. I give up, It will make you happy to hear this so I'll say it.ok GM builds the most modern and most dependible cars in the world. The rest of the world is wrong for having standard intelligent keys with push button start on base models.
 
The rest of the world is also behind GM for having DOHC engines and independent rear supsensions. Although GM is starting to sway and build cars backwards. 2007 Buick Enclave DOHC engine, 2007 CTS DOHC engine.

I don't think I would agree with that either.
 
GM does have DOHC engines. Their 4 cylinders are either all, or mostly all DOHC designs. The V6 and V8 engines are a mix.
 
Intelligent keys are cute, but not needed for anything useful.

while I am not sure, I think that the SRX's (and CTS and STS) shocks can be replaced without replacing the strut. This would save money.
