New Cars, better engines!??

Re: New Cars, better engines!??

the only thing i dont understand is why GM likes pushrods so much... even the LS7 is a pushrod if i'm not mistaken..

Because GM likes to live in the past.... Besides, who wouldn't want little metal rods going up and down, opening and closing valves like a carusel? ;)

Gm likes to make big power on big displacement engines in small outer packages. (LS7 is the same size as the GM 4.8 V8) Hell, the 5.0L Ford engine is much smaller than the 4.6L DOHC.

They make great power on pushrods. BTW, pushrod engine is newer technology than SOHC or DOHC.

Some of you guys are starting to disappoint me...

Re: New Cars, better engines!??

the new Impalas are like 3.4liter but make 250hp

while my 3.4 makes a tiny 160 :(:spank:

also the 350 runs rediculously high compresssion.

Re: New Cars, better engines!??

Technology is beautiful!
Mercedes has been offering for several years the 65 AMG engine.

604 HP @ 4,800-5,100 rpm's
738 TQ @ 2,000 - 4,000 rpm's

This is done on a little 365 CI V12 engine

Our new N/A 63 AMG engine makes:
507 HP
465 TQ

Just wait for the bi-turbo version of this engine.... care to make guesses on how close to 700 HP??? ;) Nothing official at this time though ;)

Re: New Cars, better engines!??

Nobody cares about your stupid Chryslers... :p

J/K, i drove a S55 AMG yesterday.... thing went like a raped ape, pretty freakin cool :)

Re: New Cars, better engines!??

GM's problem isn't a lack of "technology" in engines, if you want to call DOHC VVT engines technologically superior- they haven't done a good job of marketing in the past 10 years- people still think they make crappy cars like they did in the 70s and (to a lesser extent) the 80s. They've been doing better about it lately, but GMs cars have been largely bland and unexciting.

Why change from tried and true pushrod motors that make gobs of power with good efficiency (especially with the technology now that allows an engine to run on half its cylinders under normal driving conditions.)

GM may be "stuck in the past" in many regards, but engine technology isn't one of those categories.

In the JD Power And Associates quality rankings, 3 GM brands fall in the top ten: Cadillac (7) and GMC (9) Chevrolet is 14th, right under Nissan. While that's not as good as Lexus and Toyota, it's still very respectable, and isn't proportional to the large sales difference and PERCEIVED quality superiority of the Japanese companies. BTW: why is Chrysler behind GMC? For that matter, look at Mercedes-Benz: 139 problems per 100 vehicles!!!!! Perception of quality isn't accurate in assessing the quality and value of a car. Statistics matter more. The only thing I don't like about this survey is that it doesn't address what KIND of problems arise, or cost of repair. I'm betting a lot of the problems with MB are electronically-related.

Hey Firebird guys: look at Pontiac's rating ;)

IWISHIHAD$$$: you make a good point about torque curve. It's well known the LS1 has an amazing power curve: it's a good engine, that's why I used it as an example.

I don't know what the power curve is like on Nissan's 3.5 liter motor that they put in the 350Z.

Good post. MB are a joke when it comes to reliability in my experiences, looks like a lot of other MB owners are having problems for quite some time now.

I can take a guess on the 350Z TQ curve

Re: New Cars, better engines!??

Frigin JD powers

Those are customer percieved problems!!

Customer percieved problems:
Brake dust
Brake squeal
Tires don't last long enough
Brake pads don't last long enough

Bwahahahahahahah I've had several MB's at this point in my life. I have no complaints at all.

Brake dust...... it happens on ALL cars
Brake squeal.... clean your damn brake dust off your wheels!
Tires don't last long enough.... check your tire psi!
Brake pads don't last long enough.... stop riding your brakes! Constant stop/ starts aka city driving will shorten the life of them!

I've had:
2003 C230 - 38,000 miles - no problems - given back on original tires, brakes etc.
2006 E350 - 18,000 miles - no problems - given back on original tires, brakes etc
2007 E350 - 1,500 miles so far - no problems.


Obviously I can't go into this further... on the internet. Mercedes-Benz sales have hit new records every single month this year..... and for the past 11 years we have had record sales every single year.

Obviously they are doing something right ;)

Re: New Cars, better engines!??

Yeah, LS1 actually has 350hp.

You also have to think about compression ratio. 350z has 11 to 1 compression while ours has 9 to 1. They also have agressive cams that can make full use of the RPM. Plus Nissan has already maxed out the NA engine. There's a discussion of dropping the Titan V8 that would be rated at 400hp. Which will compete with Vette. Because the 350z is Japanese version of the Vette.

Also there's a Monte Carlo with a Dale Earnhardt signiture known as the Intimidator with a 3.8 engine rated at 297 hp with compression of 11.

Re: New Cars, better engines!??

Oh, and I should add this..... I have recieved prior JD Power's Survey's.

I answered them honestly - no problems with my car.

I no longer get JD Power's sruvey's.....they don't send them to me anymore.

They have no idea I work for MBUSA

Re: New Cars, better engines!??

Man, I remember when the first 3.8 came into the F-body in late 95. There wasn't a whole lot of V6 cars running 200hp. The V6 Stangs were still 145hp.

That's too bad that GM didn't continue to upgrade the engine. I guess they were too busy with the Vette.

Shhhhhh, you sound like a car salesman ;)

Anyway, i'm not suprised to see VW at the bottom of that list...

Good lord no!
