Hmm this might be the end of the die hard MB Diesel Drivers.:surprise::frown:



Back in 1936, Mercedes-Benz unveiled the first diesel-powered passenger car. It was a 2.6L four-cylinder engine that used a Bosch injection pump, made 45 hp at 3,200 rpm, and achieved 24.7 mpg. The 260D quickly became a favorite of taxi companies in Germany because diesel not only cost less than gasoline but, with a passenger transfer license, it also cost 25 percent less per liter. It was no surprise when the diesel car became a hit. The 260D led to the introduction of the 1.8L 170D in 1949.
Then, in 1954, a 1.9L, 50hp version of the diesel was put into the new Ponton unibody chassis (also called the W 121) and became the 190D. That year, journalist Bill Carroll drove this diesel car across the USA to create awareness of the new import. A Fintail (W 110) 2.0L was also sold beginning in 1961. You're less likely to find any of these models because of their age and the lower production numbers, but if you're looking for a simple car with old-fashioned styling, a 190D may be right for you.

In 1973, the W 115-series 240D was added to the Mercedes-Benz lineup, and by 1974, it came with a 3.0L, five-cylinder engine with an improved injection system. This engine produced 80 hp at 2,400 rpm, giving the car a respectable 92-mph top speed and knocking about 10 seconds off the 0-60 time (to 19.9 seconds). The 240D became one of the best-selling diesel cars of all time, with 945,206 of the W 115 cars being sold. This model with vertical headlamps also became a favorite in the U.S., so there are a lot more of them on the market than the 190D.
In 1976, due to high demand, Mercedes-Benz sold the W 115 diesel cars alongside the new W 123 models (with horizontal headlamps). It's confusing, but with the new W 123 body, a 240D comes with four cylinders and the 300D is the five-cylinder model-so count the injector lines when you go for a testdrive. The new diesels received an upgraded engine that featured a stronger Ferrolastik head gasket, an improved exhaust system, and new oil- and fuel-filter designs.
Thanks to Corporate Average Fuel Economy (CAFE) regulations in the U.S. and Canada, Mercedes-Benz decided to sell the 300CD coupe starting in 1977. By offering an additional body style (which was lighter and got better mileage), the company was able to raise its overall consumption statistics. A W 123 station wagon was also sold during this time, and now these spacious diesels are often being sold at a premium price.

At the 1977 Frankfurt International Motor Show, Mercedes-Benz debuted the turbocharged S-Class 300SD (W 116) specifically for the North American market. It had the 3.0L, five-cylinder engine and a Garrett turbocharger that bumped the output up to 115 hp. The extra power allowed the heavy sedan to reach 60 mph in about 14 seconds while getting 16.8 mpg (compared with 10.7 mpg for the gas version).
In 1981, tougher CAFE rules prompted Mercedes-Benz to add a turbocharger to the W 123-series cars. The 300CD coupe gained a turbo, and the 300D turbo sedan appeared-both were reserved for the North American market (sorry, Eastern Hemisphere). A station wagon with the turbo-powered mill was also available. For our money, the turbocharged cars are the best buys because they can be found for about the same price as the normally aspirated models but offer much better performance and still get terrific miles per gallon.

n 1983, the W 201-series got two diesel engines for the new 190D, which were called Whisper Diesels because they were completely encapsulated to trap noise. The 190D 2.2 used a four-cylinder engine, and the 190D 2.5 was equipped with a turbocharged five-cylinder that made 122 hp at 4,600 rpm and had a top speed of 119 mph. The W 201 body style is a big improvement over the models previously mentioned, and we'd suggest you jump on a 190D 2.5 if you find one for around $2,000.

and here is the story on the new petro engine that wants to kill the Diesel.

The variable compression petrol engine will arrive in an Infiniti QX50 and its efficiency gains could make diesel redundant

The Renault-Nissan Alliance is to launch the world’s first ever variable compression engine in a production car – amid claims that it will greatly reduce reliance on diesel power.

The groundbreaking 2.0-litre turbo VC-T petrol unit is claimed to offer the performance of a V6 but with much improved efficiency, and is being hailed as the ‘most advanced internal combustion engine ever created’. It will be unveiled at the Paris Motor Show next month.

I can't see gasoil dying in my lifetime.

The returns would have to be massive to make it worthwhile.

Taxis, Trucks, Diggers, Standing engines, Boilers, the hard infrastructure is an expensive outlay.
Until there are diminishing returns gasoil will be king in the industrial world.

Only the environmentalists can hurt gasoil.
