A 21st Century 240D

The Mercedes-Benz ML is the latest victim of powertrain downsizing, but this time, it’s the diesel version that’s getting its cylinder count trimmed.

For 2015, the ML350, with its 3.0L V6 diesel, will be killed off, replaced by an ML250, using the 2.1L 4-cylinder diesel used in the GLK and E-Class diesel. While the old V6 was good for 240 horsepower and 455 lb-ft of torque, the new 4-cylinder will put down 200 horsepower and 362 lb-ft. Fuel economy is said to improve with the new mill, but a big car and a small engine tends to sometimes hurt real world figures, as the smaller mill must work harder to motivate the same amount of mass. Official fuel economy and towing ratings will be released later.

While AutoGuide.com quotes an M-B product manager as saying that the change comes from consumer demand for increased fuel economy, you can bet that CAFE had a lot to do with this change. Mercedes-Benz sells plenty of gas-guzzling cars, SUVs and AMG models and has been fined over $260 million for not meeting CAFE standards. No surprise that M-B has been a vocal opponent of the regime, which it says favors large trucks and SUVs.

So what better way to juice their CAFE averages than by saddling a large SUV with a tiny diesel engine? It’s not like this is something unknown for Mercedes-Benz. How many gutless, MB-TEX equipped 240Ds did they foist upon the American public, painted in hideous hues and sold at prices far beyond what many Americans expected a Cadillac or Lincoln to sticker at. Decades later, you’ll still have to fork out a $50,725 base price for the privilege of driving an ML250 BlueTec.

We may not exactly be in the Second Malaise Era – not with the advances made in automotive safety, fuel economy and power outputs, that let us have a 22 mpg Hellcat – but this ML250 is mostly definitely a modern day Brougham. Or a 250TD, if you prefer.

    a friend burnt out his land cruiser's engine. the orig was 4 litre I-6 and he dropped a chebby 327 in it, he told me it uses less fuel and more power so. the 327 = 5.55 litre and 2 more cylinders to tote around. i guess something didn't quite added up for a smaller engine.

      There are all sorts of things that can cause a smaller engine to get worse mileage. Even when getting better mileage, cost of operation can be much better in a larger engine because it may need less repairs due to not being wrung out all the time. Theories don't always work so well in actual application. Politics or engineering, it's the same. Otherwise, you could get get a free lunch by simply building itzy bitzy engines. And as we all know, TINSTAAFL. And in case someone wants to talk about Physics, go find a physics professor and ask him how to get a fee lunch. Isn't one in physics. All laws of physics follow TINSTAAFL.

    This is unfortunate. The ML350 Bluetec drove far better than the ML350 with the gasoline 3.5L. Their customer base probably doesn't use enough throttle to know the difference between the two anyway.

  • MaintenanceCosts "But your author does wonder what the maintenance routine is going to be like on an Italian-German supercar that plays host to a high-revving engine, battery pack, and several electric motors."Probably not much different from the maintenance routine of any other Italian-German supercar with a high-revving engine.

  • 2manyvettes I had a Cougar of similar vintage that I bought from my late mother in law. It did not suffer the issues mentioned in this article, but being a Minnesota car it did have some weird issues, like a rusted brake line.(!) I do not remember the mileage of the vehicle, but it left my driveway when the transmission started making unwelcome noises. I traded it for a much newer Ford Fusion that served my daughter well until she finished college.
  • TheEndlessEnigma Couple of questions: 1) who will be the service partner for these when Rivian goes Tits Up? 2) What happens with software/operating system support when Rivia goes Tits Up? 3) What happens to the lease when Rivian goes Tits up?
  • Richard I loved these cars, I was blessed to own three. My first a red beauty 86. My second was an 87, 2+2, with digital everything. My third an 87, it had been ridden pretty hard when I got it but it served me well for several years. The first two I loved so much. Unfortunately they had fuel injection issue causing them to basically burst into flames. My son was with me at 10 years old when first one went up. I'm holding no grudges. Nissan gave me 1600$ for first one after jumping thru hoops for 3 years. I didn't bother trying with the second. Just wondering if anyone else had similar experience. I still love those cars.
