Diesels are slowly starting to get popular in the United States, with German automakers leading the front with diesel variants of their most popular gasoline models.

Of course there are some obvious benefits to diesel over gasoline, including the increase in fuel-economy, a boost in torque and the final price differential over gasoline models is generally much smaller than that for hybrids. Nonetheless, diesel fuel is a bit pricier than gasoline, which may be the reason why Americans still seem to be a bit hesitant about purchasing them.

So we figured we’d ask you guys whether or not you would consider buying a diesel over a gasoline model? If yes, then which one? Some choices you have include the 2010 Volkswagen Golf TDI, 2010 Volkswagen Jetta TDI, 2010 Volkswagen Touareg TDI, BMW 335d, BMW X5 xDrive35d, 2010 Mercedes-Benz ML350 BlueTEC, 2010 Mercedes-Benz GL350 BlueTEC, 2010 Mercedes-Benz R350 BlueTEC, Audi A3 TDI and the Audi Q7 TDI.

    Funny you guys bring this up. I'm actually considering the 2010 Volkswagen Golf TDI. Will you be reviewing that anytime soon?

  • Hedorah

    I don't know … CR just reported that it cost over $300 to refill that urine thing … that negates any cost advantage in milage ….

  • Bumblefoot

    The Jetta and Golf TDI's don't use the Urea injection.
    The Touareg TDI does, but it's only about $50 every 5,000 miles

  • Bumblefoot

    I just bought one and it is a great car! I'm on my 2nd tank of gas and averaging 40 mpg so far.

  • KC

    Yes, bought a TDI Sportwagen for the wifey. It's a fantastic vehicle. I'd consider a 335d for my next car but for the price premium & the only transmission being an automatic.

  • watcher68

    absolutely would consider it and I am! I previously owned a 2000 VW Golf diesel which was a good but not great car. Super mileage, useful though too slow to keep up traffic. I currently own a gas BMW 330i but I am looking at buying a used Mercedes E-Class diesel 2006 – 2008. Superb mileage and all the space and usefulness you could want in a mid-size sedan. Also, I might wait a year to see if any BMW diesel's get traded in early. They should be quite the bargain next year.

  • Travis D

    Already bought a 2010 Jetta TDI with no hesitation over a gas car. With some patience and persistence I got a killer deal.

  • zermatt

    I have to agree with you on the premium that is attached to the cost of the diesel on the 335 or the X5 for that matter. To recover the increase in price takes much longer than the lease period and that defeats the benefits of the lease.

  • Mogar

    Don't think so. The Diesel premium where I live almost completely negates any savings that the increased fuel economy would deliver.

  • Marvin I. Honig

    I bought a X5 diesel 6 months ago and am totally pleased with its performance. My last SUV was a Mercedes V8 ML500 and the best mileage I got on the highway was 19 mpg with premium; now I usually get 20 mpg around town, and the diesel has all of the power I could want.

  • grasspress

    sure, but i'm already sold. i bought a sprinter van 4 yrs ago. it's reliable, torquey, and i can get over 30mpg with all-day interstate travel at 55 (over 700 miles/fill-up), and i can get over 25mpg around town without being careful.

    i buy a new car every 10 yrs so i try to buy one that will last. my 10 yrs are up this year and i'm looking at the 2010 vw golf tdi (i would be looking at the polo but it's not available here).

  • AFA

    Absolutely. Pros (many) and cons (few) have been noted by others here. A concern brought up occasionally is recouping the cost differential. I prefer to place the emphasis instead on the fact that diesels consume less fuel. Some of the non-U.S. suppliers of the crude oil range from friendly nations to unsavory and brutal regimes. The less we buy from the latter group the better. As diesel technology evolves over time, the possibility of “manufacturing” fuels from non-petroleum, non-food sources will emerge.

  • lindtech

    As a long time VW and diesel owner (currently have a 2009 Jetta TDI Wagon), I am completely sold on diesel. The overall cost benefits overcome by a great margin any differential in fuel costs. The EPA ratings on VW diesel fuel mileage is severely underrated and the gas ratings are overrated. Real world mileage is similar to the best hybrid numbers and better than some. Used diesel car prices are considerably higher as well.

    My wife and I are keeping a close I on the rebirth of the diesel engine market in America as we shop for new, fuel-efficient transportation to replace her aging 2003 Toyota Prius.

    My wife loves her hybrid, but the ever looming question of “how long is this hybrid battery going to last” is a concern that is always in the back of our minds. (Both my wife's mother and sister drive Honda Civic hybrids and both have had to have their hybrid batteries replaced…one under warranty and one out of pocket.)

    We have looked hard at the new Volkswagen Jetta TDI Sportwagen, but with the supply/demand issues, dealers aren't willing to budge much off of MSRP and I can't stomach the thought of paying sticker price for a vehicle so we are still weighing our options. Plus, I've been reading reviews about poor VW quality & reliability issues from consumers on Edmunds.com which has me concerned.

    Diesel fuel is about $0.20-$0.25/gal. more expensive than regular unleaded in our area so the math works out in the diesel's favor due to the better fuel economy. Historically, diesel engines will last longer than a gasoline equivalent but you just need to have a car that surrounds your engine that won't completely fall apart after 100,000+ miles like most vehicles seem to do today.

    Hopefully, American automakers will get a clue and start offering environmentally-friendly diesel options in their small/mid-size car fleets….but I'm not holding my breath!

  • rloring

    Yes count me in.
    Diesel technology and biofuels are finally getting some decent attention. Many folks do the math at a point in time and consider diesel not worth it, but things change. Diesel fuel prices seem to fluctuate more dramatically than gasoline. Diesel engines are surprising forgiving on fuel mixtures so lets hope the bio kicks in a big way sometime soon.

  • gooster

    Another factor to consider is that the diesels are eligible for a tax credit (the lean burn credit). I just put a deposit down on an Audi A3 TDI; considered the BMW 335d. The 335d is a great car as well. Right now, BMW has an additional mfg incentive that makes it less expensive than the gas version. Diesel in California is about the same price as mid-grade gasoline. I also drove for 18 months a MB B200 diesel while in Europe; it was terrific and I would buy one of those if they sold them in the US.

  • SR

    I plan to buy a new car in the next 12 months and I have already fixed my mind; it is going to be a diesel. I cannot help but think about it every day. Either it is going to be a Golf TDI, A3 TDI or Jetta SW TDI.

  • Ralph

    I bought the Jetta Sportwagen TDI in October 2009. It is an exceptional car with many advantages. During a recent trip to Arizona from California, driving between 75-80 mph, we averaged 41 mpg. I researched this car for a year before buying, and I'm completely satisfied.

  • Lynn

    Yes I would buy a bio-diesel running car. I save up and pay extra to use as much as I can. I do wish the glow plug manufacturers could make a glow plug though that doesn't burn out so fast with the higher temps of the bio-diesel. I would love to see a diesel hybrid.

  • SR

    Don't forget that by the end of this year, you get a $1,300 tax credit if you purchase a diesel-powered car/truck.
