CEO Confirms Chevy To Sell Diesel Cruze In US 349

s122604 writes "For the first time in almost 30 years, a U.S. carmaker is planning to market a non-truck diesel vehicle in the U.S. — the Chevy Cruze. Estimated MPG for the automatic transmission version is in the mid 40s, which is better than the only other small diesel sedan sold in the U.S. (the Volkswagen Jetta), and slightly better than their gasoline powered 'Eco' model... I'd like to know what the MPG on the 6-speed manual version is."

    There's other niceties with diesel, the engines last longer and run at a lower RPM. There's more torque, people buy horsepower but drive torque as the saying goes.

    There's no ignition system to worry about, no plugs and so on.

    The downside is the soot that comes out the back when accelerating hard.

      The down side is price. It can cost almost twice as much for the engine in a TD as in an ordinary gasser, and the price of the vehicle comes up significantly in such a case. It has to do partly with economies of scale, which is why auto manufacturers used to simply buy diesels for their light trucks; Dodge using Cummins and Ford using International-Navistar. And indeed, they always have and still do buy the engines for their heavier trucks; Everyone buys from everyone, except IIRC only Ford still buys from International. I believe everyone else is using a Cat or a Cummins; so does Ford. Chevrolet, as the owner of Allison, is the only company which didn't have to do this back in the day. Unfortunately for them, Allison totally blew the 6.5, which was designed to be built on gasser production lines. This is not precisely the same thing as saying that it was modified from a gas engine, but it's the next best thing.

      The good news for Chevy is that they no longer wear the "I can't build diesels" crown, that now goes to Ford. I just got the line from a euro mechanic who also owns a bunch of domestics, and who used to have a truck similar to mine but much older (with a 6.9 -- the 7.3 is a bored out 6.9, basically.) Ford has a coolant-filled EGR that frequently fails. Because the turbo is tucked into the valley to save space, the exhaust manifolds turn up instead of down. The result is that when the EGR fails (and it invariably does) the coolant empties into the cylinders. Very classy. The tendency away from Ford diesels worth buying actually began with the 7.3 powerstroke, which is the last machine worth buying from them, I believe it ended in 2000. In an effort to make the valve covers cheaper (I am not making this up) they put everything under the valve covers. As a result you have a valve cover gasket with wires and connectors integrated into it that frequently fails and costs a mint to replace.

      Finally, it costs about four to eight times as much for the 'stroke HPOP as for my fuel pump, and I get the same mileage as a 'stroke, and with the aftermarket turbo I have the same power as an early 7.3 'stroke without modifications.

      The best diesel I've ever messed with is the OM617.951 Mercedes engine, anemic by modern standards but I have all the power I need in my car. It's a work of art in a way that very few engines are, and it's matched by a truly excellent injection pump that can take a raft of abuse, unlike the DB-2 in my Ford... and which was also used by Chevy/Allison on the 6.2 and 6.5 lemons.

        I paid $21.5k for my 06 VW TDi Golf. At the same time the same model with the eco 4 cylinder gas engine was selling for just a hair over $19k.

        I get 45 miles per gallon, and I drive like my feet are made of led. I put 40 miles of interstate driving on to my car twice every day. Toss in a few random arrands and I'm easily doing 350+ miles per week. But I usually get 650-700 miles per tank. Only having to fill up every other week really takes the edge off of fuel price hikes. I bumped into a hyper miler last summer in an 06 Jetta TDi (sedan version of the Golf) he was getting 56mpg, and he was going to swap his 5th gear for a higher ratio and was projecting 60+ mpg.

        In 2010, my wife's car died. So we figured we'd get her a new one in the cash-for-clunkers deal. Only I wasn't about to shell out $500+ in car payments. So we went to the bank to see about refinancing the Golf. That's right, a CAR with enough equity to be able to refinance. With 40k miles and 4 years on it, it still blue booked for $17k. Compared to the gas version that had a KBB value in the $10-12k range.

        So yeah, the Diesel engine costs more. But if you intent on reselling your car in 5 years or so, you'll come out up on the deal. And if you don't intend to sell it, you'll come out ahead on fuel savings over the life of the car.

      I have a 2010 Golf TDI, there is no soot, there is no smell either. Had a big doubter at work who spouted all those anti-diesel myths of days gone by come out with some others to see the car when I bought it. He even sat right behind the exhaust pipe when I started it and acknowledged all he could detect was hot air.

      My commute is 26 miles to work, 27 on the way home; yeah its not the same, based on traffic patterns. I track my fuel usage on fueleconomy.gov and my average since June of 2010 has been 41.7. My commute has no interstate, there are some four lane areas but many more 45 and 35 mph two lane country roads past subdivisions and such.

      My highest average over the commute in was 51.2, the lowest which only occurs on the way home was 37+. Acceleration is my mileage killer. If I catch every light green I can see some great numbers. Since I do not use an interstate or other limited access road I have alternatives and never get trapped in stop and go.

      Another note, I pay the same as premium gasoline. However in two recent run ups in price Diesel stopped increasing in price and I actually saw regular gas cost more. Even when I pay $4 a gallon and regular is at $3.60 I do better than everything short of a Prius for efficiency. Most of the current 40+ crowd I see advertised are lucky to get above the low 30s consistently.

      Only improvements I want to cars are regenerative braking and electric propulsion assist. I have two wheels that aren't powered. A small battery pack or something used only at launch would do wonders to overcome the losses I incur when accelerating from a stop. Plus I would not mind some of it back when I am stopping to aid that starting.

      What does this mean? There has to be some sort of ignition system [to worry about :-]. I wonder how well this car will start in -20F weather.

      > The downside is the soot that comes out the back when accelerating hard.

      I always saw that as a PLUS. Usually don't accelerate _hard_, but when that idiot is riding you it's fun to "dust them" and with the torque ... buh-bye.

      • Diesels don't rely on coils and spark plugs. The compression ratio is high enough that the air heats sufficiently during the compression stroke to make the fuel autoignite when it is injected into the cylinder at/near top dead center. On the other hand, that means the injector pumps (or single pump in a common-rail system) must develop extremely high pressure in order to actually inject the fuel.

        For cold starting, there are glow plugs to help heat the air - they are basically heating elements.

      • What does this mean? There has to be some sort of ignition system

        Nope!

        Diesel engines ignite the fuel/air mixture by compressing it. As the mixture is squeezed, the temperature rises, and if you squeeze it enough, it goes bang. No external ignition systems such as spark plugs are needed.

        Old-fashioned diesel engines did not, in fact, have any electrical system other than the starter motor --- once they were running, you could disconnect the battery and it would continue running fine. In fact, they were pr

        "A diesel engine (also known as a compression-ignition engine) is an internal combustion engine that uses the heat of compression to initiate ignition to burn the fuel, which is injected into the combustion chamber. This is in contrast to spark-ignition engines such as a petrol engine (gasoline engine) or gas engine (using a gaseous fuel as opposed to gasoline), which uses a spark plug to ignite an air-fuel mixture"

      another downside of modern diesels is that the engine will outlive the vehicle by a substantial margin. 200k is nothing for a diesel. gas engines start to give up the ghost before that.

    • by dfghjk ( 711126 )

      "... people buy horsepower but drive torque as the saying goes."

      It's a stupid saying offered, and repeated, by stupid people. Torque is an intermediate mathematical term. Horsepower is what gets the work done, and when people talk torque, what they're really talking about is power curve. You can get any torque you want through gearing.

      • To be fair, when people talk about torque, they mean the peak torque figure published by the auto manufacturer. The saying comes from the fact that almost all gasoline engines reach peak torque at lower RPM than peak power, and most people operate their engines predominantly at those lower RPM ranges. So an engine with a quoted 200 lb/ft of torque at 2800RPM and 200 hp at 6000RPM will seem faster under normal driving conditions than an engine with 150 lb/ft of torque at 5200RPM and 250HP at 8000RPM. It's a

    I love driving my 300SD, when I drive the Astro (our only gasser; my F250 is a turbo diesel also) it feels totally gutless until I stick my foot all the way in it because comparatively it has no low-end torque. Amazingly the 300SD has good pedal response up to about 90... that's amazing because it has 120 bhp and 170 rated foot-pounds, and an estimated top speed about 105.

        That varies but bear in mind that it is actually cheaper on a per-horsepower basis. Diesel has to be 15-20% more expensive to cost more for the same amount of horsepower. $/watt, diesel generally comes out ahead, even if it is slightly more per gallon at the pump.

      Not at all. A manual in a car without 200+ horsepower is a big advantage. Not everyone wants to get 12 mpg just so they can avoid learning to drive a car. An automatic can't know a steep grade is coming soon and to shift down early, by the time it shifts it is already too late. Sure you never notice in your mustang, but those of us with normal cars sure do. An automatic also can't shift down and coast in gear to slow as you come to a red light. Instead it lets you coast without engine breaking and you get t

    • The range is a big reason for choosing a diesel.

      Also, the torque on a diesel makes it well suited for many applications.

    • A non-turbo diesel engine and a diesel engine are nearly identical, the process that is used to make a engine a 'diesel' engine needs very little work to be turbocharged. This is why often diesel engines only come 'turbocharged' and one reason I've heard it said that turbocharging a diesel is 'free'. So I don't think you quite understand how a diesel works or why turbocharged diesels are so common. While I'm not an expert by any means, I have in fact read up on the subject I suggest you do to.
