2014 chevy cruz diesel

[Scooby074]

Preaching to the choir there bud :thumbsup:.

That is my preference, and I wouldn't be buying new w/o a traditional stick trani.

Some people want/must have an automatic though..... GM is probably correct to launch with an automatic, esp. in the USA market.

If Cruze diesel sales do well, hopefully a stick option gets added soon.

They should launch with BOTH. As I mentioned earlier, several reviews I read pointed out that the automatic trans was the cars weak point, the engine was strong. Having a manual would allow those who dont like that particular auto an option. It could keep a buyer from looking at the competition. Not that I personally would even bother looking at the auto in the first place

Very interesting,

Instead of the 150 lb-ft of torque offered by the Cruze痴 gasoline-burning counterpart, the new turbo diesel will provide 258 lb-ft of torque at 2,000 rpm, delivering a fuel efficiency of 46 mpg to the Cruze

And

Torque @ RPM 264 @ 2600

from Compare Compact Cars: 2014 Chevy Cruze | Chevrolet

While the VW TDI puts out 236@1750.

I noticed last night at 2000 rpm I was doing about 70 in my TDI.

Oh -
And

To some extent in this thread, but I've also read it many times in others, plenty of tDI owners do NOT baby the throttle, as these diesels don't degrade their mileage performance to the extent gas motors do when driven hard.

According to thoughts in 2009 the proper way to break in a TDI was to have frequent applications of the throttle. I know that I've found myself on the open road thinking I was doing 70 only to look down and see 80 plus.

Torque - there ain't no substitute ! Well, at least until Matter Transporters are affordable

Years ago (talking pre-tDI), a buddy of mine got his worst speeding ticket ever (and, back in those days, he already had some doozies), test driving a VW diesel.

Back then, I hadn't seen him for a while, and he told me this story when I commented that those VW diesels might not keep up that well on the highway. We both had a good laugh. It was a well controlled drive (salesman was in the car with him), just way too quick for the guy with the radar gun.

With a typical well planted German designed chassis, and a torque laden diesel, you really have to pay attention, esp. if you don't drive 'em often. It's deceptively easy to get clipping along at significant speed.

i once had to rent a car in germany to get from point a to point b, which was about 100 miles away. i ended up with an audi wagon with a tdi engine (i presume the high output version, although i have no proof of that). great, i said, this thing will be sluggish as **** and i'll be on the autobahn almost the whole way. it wasn't what i would call sluggish, not at all. that thing would move along rather briskly. and then i got on the autobahn.

i decided that i would bury my foot and "see what she'd do" once i got out of the metro area and the speed limit disappeared. i figured it would top out at 100 mph or so. heh. after 5 minutes of moving right along, i scared myself silly passing a truck. i was running at night, and that truck just jumped right out of the night and up into my grill. i got out of the throttle, made a veryfastindeedthankyewverymuch lane change, said several foul words in a very shaky voice, and then looked down at the speedometer. i was still going faster than 150 mph. i don't know how fast i was going, but my porsche 911 won't go that fast. that is the fastest i've ever driven and i don't really know how fast it was.

as far as automatic transmissions, i was a hard core manual transmission for almost all my life. then i spent ten years dragging 80000 pound trucks up and down the rocky mountains in colorado, wyoming, and montana and if i never shift another gear as long as i live it is perfectly ok with me. automatics uber alles!

To reduce the loss of combustion chamber thermal energy inherent in un-throttled diesels and gas turbines. Then yes the variable duration intake cam limits airflow into the engine at part load. Breathing 100HP worth of air through the engine when it's cruising along making 30HP just washes heat from the combustion chamber out the tailpipe instead of pushing on the piston.
The variable cam timing also allows full combustion chamber filling with short duration and short overlap while cranking for max heat generated on the compression stroke in order to start. However when reved up the cam timing increases to allow the VM diesel to breath and make power a 1000rpm past where a conventional diesel falls on it's face.
The dual over head cams also allow aggressive acceleration and deceleration ramps on the cam lobes not practical with a pushrod engine. More flow due to more area under the curve with the same duration. Valves can be opened faster and farther off the seat for more breathing with the same duration with the DOHC than with pushrods.

People here have no idea, unless they've actually driven a modern diesel like you describe. Not for nothing, even a "sedate" estate like you drove would have dinner plate sized brake rotors.

Aversion therapy - I understand your point - big difference when doing something because you have to.... a million times with a stick.....

Thanks for that explanation.

I seriously doubt you will see a manual. Just like in trucks they seem to be a thing of the past.

Manuals are up in the last few years. Plus they offer manuals in most of the Cruze trims as it is.

At this stage of the GDI market cycle, that is a selling point in my mind.

In addition, if they still have an inline (with the fuel line) Fuel Filter, they'd get 2 extra points from me.

The Cruze eco manual has one of the highest rated EPA highway milage for non hybrid gas engine at 42 mpg it ties the vw diesel. So what if its not a gdi engine. that high pressure fuel pump is something people complain about in diesels when it comes time to fix it because they are so darn expensive. The ECO will generally give 43-46 mpg at 70 - 75 mph on summer fuel.
