2014 Chevrolet Cruze Diesel Rated At 46 MPG Highway

Follow Antony

The 2014 Chevrolet Cruze Diesel will be something of a highway star when it goes on sale, with an EPA-estimated rating of 46 mpg highway.

That's better than previous estimates of around 42 mpg, and if other diesels on the market today are anything to go by, some owners may find themselves beating even those figures.

The healthy highway rating should be enough to endow the Cruze Diesel with a 700-mile highway range, or ten hours of highway driving--you'd be stopping for food or bathroom breaks more than you'd need to stop for fuel.

Chevy has been keen to pair economy with performance on the diesel Cruze, mindful of some customers' perceptions of diesels as slow and noisy. The 2.0-liter diesel unit develops a punchy 258 pounds-feet of torque and 148 horsepower, and an overboost function can raise torque to around 280 lb-ft when you really need the performance.

Equipped with a six-speed automatic transmission as standard, the Cruze TD can reach 60 mph in 8.6 seconds, so performance shouldn't be an issue for most buyers.

2014 Chevrolet Cruze Diesel Ultimate Guide

The 46 mpg highway rating puts the Cruze 4 mpg ahead of the Volkswagen Jetta diesel equipped with either manual or DSG automatic transmissions.

The Jetta TDI DSG does have a lower starting price, at $24,950 including a $795 destination charge compared to the Cruze's $26,505 including $810 destination, but Chevy says the Cruze is better value--offering a MyLink infotainment system, leather trim, 17-inch alloy wheels, a 5-year, 100,000-mile powertrain warranty and a two-year maintenance plan as standard.

Chevy has high hopes for the Cruze diesel. The Cruze itself has passed the 2-million car mark globally since its introduction in 2010, and 33,000 diesels have already been sold worldwide.

Some estimates suggest that diesels could make up 10 percent of the U.S. car market by 2015.

The Detroit News reports Milwaukee and Baltimore have been identified as two key cities for diesel cars, and the Cruze TD will debut there first--the first cars arriving late June. The car will then be available nationally by early fall.

With its 46 mpg highway rating, would you pick Chevy's diesel over the German competition? Leave your thoughts in the comments section below.

  1. As I recall VW's small diesel pick-up got over 50MPG back in the late 70s. I don't think we are really making that much progress. I am sure this vehicle is a lot cleaner emission wise

  2. It's hese kinds of ridiculous comparisons that irritate me. Emissions are down what, 90-99% from the era you referenced and you're also comparing this to vehicles without ABS, without AWD, without complex air bag systems, without much more stringent emissions equipment, etc... The EPA testing pattern was also changed a few years ago to make the stated EPA mileage closer to real world results.

    There has been tremendous improvement in ICE technology, emissions, mileage, etc. but it's people like you making unfounded statements not rooted in facts that keep that completely incorrect stereotype out there and alive... Thanks...

    It doesn't mean we don't need EVs, hybrids, diesels, etc. but again, your comments are nonsensical.

  3. Most of those old car advertisements from the late 70's and early 80's were false on their MPG numbers.

  4. Do we really need 250-280 foot lbs of torque in a car whose regular engines do just fine with 120 foot lbs of torque? I want to see a 20 psi eco boost putting out 120 ft./lbs like the regular engines do. Then lets compare diesel to Gasoline.

  5. huh?

    If you look at the power of the diesel vs. its gasoline engine, it is very close. The extra torque just means the transmission gearing ratio will be different and engine will be running at a much lower RPM.

  6. The gasoline engines do about 120-130 hp while this is doing 154 hp which is base Engine CUV territory. But torque on those gasoline engines is also 120-130 foot pounds of torque. Truck V8s make 250-300 foot pounds of torque, right around twice the power of the compact car engines. Horse power is not real power, torque is real power.

  7. Also what I meant with the comparison is not just eco boost a gasoline engine but also make a diesel variant at the base/normal engine power level.

  8. Real Power? Torque is a measure of turning force (think torque wrench). There does not have to be any motion to have torque, thus no work.
    Horsepower is the rate at which you can do work and is dependent on torque and RPM.
    Torque is a component of horsepower. HP = torque X RPM ÷ 5252

  9. NO! After rebates and guv'ment tax credits, I will have paid $27k for my Volt, a vastly superior car to the overpriced diesel smoker Cruze. After adjusting for the higher cost of deisel, it does no better than the Cruze ECO in economy, but at $6k more? Fugghetttabouttit.

  10. I'm eager to see how the Mazda6 with their new diesel will stack up. It is supposed to be available by the end of the year.

  11. "NO! After rebates and guv'ment tax credits, I will have paid $27k for my Volt, a vastly superior car to the overpriced diesel smoker Cruze"

    Superior in what way? With a gasoline engine and a hybrid drive, it is much more complex than the diesel Cruze. There is no way, laden with all that extra complexity in mechanics, electronics, electrical and software, that the Volt could possibly be superior.

    Sorry, but go to your nearest library and pick up some starter books on mechanical engineering, physics, electronics and software engineering, then come back to discuss.

  12. The Volt is superior b/c it has more torque, smoother, quicker response and far quieter ride...

    And so far, my so called "fake" MPG of 133 is cheaper to operate than the comparable Cruze with the current diesel price.

  13. Superiority is measured not only in performance, but in longetivity and simplicity. We do not have enough data to conclude that Volt will indeed be a long lasting vehicle, and it would have to last at least 20 years (yes, that long!) for us to be able to conclude that; and we already know that the Volt is anything but simple.

    It does not make sense to own such a complex vehicle if your intent is not to waste money. If you do not care, then that is a different story.

  14. Government subsidies for the Volt are unsustainable as are the $5,000 cash incentives from GM. Your $27k car is really a $40k with handicaps. I'm not a fan of diesels but ridiculous comments like this need to be called out. We can't design every new car assuming the government and the manufacturer are going to foot a large portion of the bill ($14,000). It's not a sustainable business model for the manufacturer or society.

  15. Is government incentives for Toyota's Prius Plugin and e-Rav4 equally unsustainable?

  16. There are more comments in this thread
  17. How much/yr to fill the Urea tank?

    As Chris said I owned an 80? Rabbit diesel which got over 50mpg version of the pickup which I wish I could find one of to convert to electric. So why is it so hard now?

    I did run mine on 75% filtered veg oil/25% diesel, biodiesel or kerosene made it very cheap to run.

    But I'm getting 250mpg equivalent now on electric which now PV has dropped so low, I only need 500watts/$500 now, of for 25 yrs of fuel. sunelec for the panels among other sources.

  18. Jerry... seriously feel free to do even five minutes research on this. I've commented above, but what's the point after awhile? People like you ignore the reasons despite their easy availability.

    Vehicles now get much better mileage than in the 1970s, as every possible metric confirms. This despite an average roughly 1,000 extra lb. in weight and a more difficult EPA mileage/emissions test that was not in place in the 1970s.

    But please, keep incorrectly stating that there hasn't been any progress. There has been a lot of it despite your apparent need to pretend that there hasn't been. Does emissions being down over 90% from the 1980s, even, also not count in your world?

  19. Chevy says $10 every 10,000 miles. 4.5 gallons of it

  20. Well, 1 step in right direction.

  21. I'd love to consider it - as soon as Chevy offers either the 5-door hatchback or true wagon version, both of which are available outside the U.S.

  22. By the way, I had the opportunity to study the diesel engine in the Cruze for the U.S. market; I am sorry to have to write that it is a what we call interference engine, and it does not appear to use a chain, which means that if the timing belt skips just one tooth, the pistons can hit the valves.

    Once this happens, the valve will be bent and the valve seats will shatter.

    I am also sorry to write that this engine is basically the same design we had in the Opel Kadett 1.6D in the '80's, which is a shame.

  23. So is it still "superior" to Volt in your opinion with this kind of design?

  24. If the gasoline engine in the Volt is also an interference engine, then yes, it is. Even if it is not, this is a tough call. In the Volt, you will always have the complexity of the htybrid drivetrain and the software. There is no escaping that in the Volt. The Cruze will be very, very simple. They are two opposites that could not be more different from each other.

  25. Here in American the Opel Kadett was sold as the Isuzu I-Mark.
    I have the I Mark advertisement from '82 on my Pinterest if you want to see the write up on it:

  26. Actually, it was sold as Pontiac LeMans.

  27. Pretty good for a 2 Liter turbodiesel. I hope it comes with auto start/stop and I hope it gets a CVT for an automatic eventually so the automatic can get decent city mileage. Hmm, only rated for 27MPG in the city and only 33MPG combined according to some sites (like gmauthority) due to the heavy 3475 pound curb weight + slushbox. Impressive 0-60 of 8.6 seconds with the diesel and the heavy weight.

    It seems like too little advantage for the increased price, weight and reduced cargo space.
    Increased weight: 3100 pounds for the regular Cruze, 3475 for the diesel.
    Reduced cargo space: 4.5 gallon Urea tank for emissions takes up space.
    Because of the increased weight and the slushbox automatic, city MPG isn't improved. If you cut down the cur

  28. If you cut down the curb weight to something less than 3,000 pounds and took out the slushbox for a CVT or dual dry clutch and add auto start/stop. It'd be a better rounded vehicle. Maybe reduce the diesel to 1.6 liters if you can get the curb weight down enough.

    But see, you can't beat a Prius on the EPA tests and difficult to beat in the real world. Their Atkinson cycle gas engine and Hybrid-Synergy-Drive system is too good. But you can get close on the highway with a tad more power, though the heavier curb weight (~3050 vs ~3475lb) kind of saps that away.
    Also keep in mind that a modern diesel isn't much more efficient than a similarly sized modern gas engine, it just has more energy to work with since diesel contains more energy than g

  29. contains more energy than gas. An Atkinson cycle gas engine can be more efficient than a diesel because of simple emissions equipment and good thermal efficiency


  30. ...Note again that this is based on the same displacement (3.0 liters) and same max power output (225 kW).

    The 1.8 liter Atkinson cycle gas engine in the Gen 3 Prius has a minimum BSFC of about 220 g/kWh, so even that is not as efficient on an energy-equivalent basis as the 3.0 liter BMW diesel.

  31. Sometimes, people want diesel b/c they care about performance that Prius lacks...

  32. Diesel fuel does have more volumetric energy than gasoline, but that's only part of the reason diesel cars get better fuel mileage.

    For example, BMW has gasoline (turbo-GDI) and diesel (sequential turbo) versions of a 3.0 liter, 225 kW engine. According to BMW data ("BMW Technology Day 2009.EfficientDynamics."), the diesel version has a minimum brake-specific fuel consumption (BSFC) of 197 g/kWh while the gasoline version has a minimum BSFC of 245 g/kWh.

    Since gasoline actually has slightly more energy per unit mass than diesel fuel (http://en.wikipedia.org/wiki/Brake_specific_fuel_consumption ), the diesel is 26.8% more efficient than the gasoline equivalent.

  33. I see many are disappointed that this engine won't put big bucks back in your pocket. Like all American myths ie; cut taxes [it never really happened] GM should have been auctioned off to save money because it can't compete [now quite laughable] and Republicans hate big government [just the opposite when you look at federal employee figures by president. The idea behind the huge increase in mileage is to reduce dependence on foreign oil. The USA is now at a point of producing as much oil as Saudi Arabia. Republicans don't like anybody to be dependent on anyone--so why do today's Republicans want to go back to DEPENDENCE on foreign oil. Please make up your mind.

  34. My 1992 Geo Metro Xfi's window sticker says 53 city/58 highway, with my best being 62.8 mpg. It has 355,000 miles on it. I bought it new and will buy another Chevy when mileage is at LEAST equal to my 21 year old relic. I am still waiting. Also the emissions were the lowest of them all (tied with the original Honda Insight)

  35. @Marty: Yes, but as we frequently have to point out, your 1992 Geo Metro could not be sold new today.

    It does not meet current emissions or fume-capture standards, and it is grievously far from complying with current crash-safety standards. Its acceleration of 13.8 seconds would also likely be deemed unacceptable by a majority of today's buyers.

    Note that the current two-seat Honda CR-Z weighs fully 700 pounds more than the Honda CRX of 20 years ago whose styling it evokes. Aside from 100 pounds or so of hybrid hardware, the majority of that is for much, much stronger crash-safety structures.

    Bring a 1992 Metro up to current new-car standards and let's see what kind of mileage it gets.

  36. Odd that they could not be sold today, when in 2014 Elio Motors can make a two seater that boasts 84 MPG hwy.

  37. This car is a joke when not piloted by the great Ivan Muller. Rental styling and overpriced and not even spacious - I've held up better in the backseat of an old civic.

    That curb weight puts the punchline on the joke though - what a porker. Most obscure Euro cars just crib a TDI.

    If gas engines could do leanburn and be throttleless like diesel, they would absolutely bury diesel. These are old ideas, but shouldn't the advent of DI help make this possible?

  38. I recently sold my VW Sportwagen TDI because I have a very short commute......the lifetime fuel mileage was 33.8......
    I bought a 2013 Jetta Hybrid.....Now this is what a hybrid should be!!! a real transmission! and Turbo charged engine and my average gas mileage is already way above what my TDI was.....Like it!

  39. I would buy the Chevy Cruze in a heartbeat if only it was available as WAGON with AWD!!!
