Old dog learns new tricks

Mercedes has outfitted a 1992 190 E 2.6 Sportline with a modern diesel engine from the C 250 CDI BlueEFFICIENCY.

Designed to demonstrate the progress diesel technology has made in the past 20 years, the "new" 190 D BlueEFFICIENCY boasts a OM651 common-rail diesel engine with 150 kW (204 hp) and 500 Nm of torque. 0 to 100 km/h comes in 6.2 seconds, which is insanely faster than the 1983 190 D's time of 18.1 seconds.

This huge leap in performance is due (in part) to the OM651's 500 Nm of torque, which is more than twice as potent as the most powerful W 201-series model (the 190 E 2.5-16 Evolution II, built for DTM homologation rules). Another interesting fact is the OM651 engine produces 72 hp more than the OM 601 engine of 1988, while consuming 2.4 liters/100km less.

Compared to the Mercedes 190 D, the C 250 CDIBlueEFFICIENCY is 385 kilograms heavier but boasts more interior space, a longer wheelbase, the latest luxury items, enhanced safety features, and improved aerodynamics.

The Mercedes 190 D BlueEFFICIENCY experimental vehicle - Back to the future

Baby-Benz with an up-to-date C-Class diesel engine

  • Driving enjoyment: almost three times the output of a 190 D
  • Economy: considerably more frugal fuel consumption
  • Protection: many more safety and comfort features today
  • What if? Practical implementation of a theoretical discussion

From the outside it looks just like a more than 20 year-old Mercedes 190, tens of thousands of well-preserved examples of which can still be seen on Germany's roads. Pressing the accelerator tells a different story: equipped with the ultra-modern OM651 common-rail engine developing 150 kW / 204 hp, the Mercedes 190 D BlueEFFICIENCY shows the full potential of this new four-cylinder diesel engine. With a maximum torque of 500 Nm between 1600 and 1800 rpm, this experimental car has more than twice the torque of the most powerful model in the old W 201-series. The 190 E 2.5-16 Evolution II, which was presented in 1990 and produced 502 times as a homologation model for the Group A DTM touring cars, "only" manages 245 Nm.

The idea for this unusual experimental vehicle came about during an evening discussion about the enormous developments in diesel technology over the last 20 years. The question was: "How might one make this progress directly tangible, in isolation from the equally profound changes in the safety and comfort of the car as a whole?" The result was a factory-tuned car of a different kind: the 190 D BlueEFFICIENCY. It accelerates from 0 to 100 km/h in 6.2 seconds. It therefore manages this standard sprint 11.9 seconds faster than a 190 D of the time, which caused a sensation on its 1983 introduction with its newly developed, fully encapsulated "whisper-diesel".

The differences between the two diesel generations are even more impressive when it comes to fuel consumption: despite the significant increase in output by 72 hp (OM 601, 1988) to 204 hp (OM651, 2009), the new engine in the old body consumes 4.9 litres per 100 kilometres (NEDC) instead of the 7.3 litre figure for 1988.

But what is really astonishing is that measured according to the DINstandard used during the time of the 190 D, the Euro-Mix consumption of the current C 250 CDI BlueEFFICIENCY is a mere 4.6 litres per 100 kilometres, and 5.1 litres per 100 kilometres according to the present NEDC method. This represents an improvement of around 30 percent - not to mention the exhaust emission levels.

The playing field is by no means level: a Mercedes 190 D is 385 kilograms lighter than a current C 250 CDIBlueEFFICIENCY, for example. In addition to more interior space - the current C-Class model is 16 centimetres longer, and around nine centimetres wider and higher than a 190 - this is due to the high standard of comfort and safety features.

As a genuine Mercedes, the model 190 was ahead of its time in terms of safety technology. Nonetheless, customers at the time enjoyed nothing like the extensive array of passive and active safety systems to be found as standard in the current C 250 CDIBlueEFFICIENCY. These include seven airbags, the adaptive AGILITY CONTROL suspension and numerous assistance systems such as ESP® and

ADAPTIVE BRAKE. Comfort-enhancing features like the ergonomically exemplary, multi-adjustable seats or electrically adjustable and heated exterior mirrors also contribute to the higher weight.

A number of factors are responsible for the outstanding efficiency of the current C-Class. Aerodynamics is one of them: with a Cd figure of 0.34 the 190 set an example for its time. The new C-Class betters this figure by far, however, and is once again the trendsetter in this segment with a Cd figure of 0.27. The progress is equally impressive where the powertrain is concerned: while the 190 D was equipped with a four- or optionally five speed manual transmission, the C 250 CDIhas six gears available. Plus a large number of friction-reducing measures. The radiator fan, power steering and generator also operate much more efficiently than 20 years ago.

Great idea and implementation. Proves again that weight spoils all the fun in modern cars.

It was very nice. I have a similar project, w201 with engine a gearbox SLK 200 Kompressor 2003 (R170). Now I need to star the engine. How do you do the electric instalation? If you can help me, please contact me vascpires@gmail.com Thank you Vasco

that car STILL looks good, the 80's and early 90's had some of the best looking Mercs IMHO. but im liking the new ones (2010+) too...

Are you kidding, is that c class 350kg heavier than the 190D, that's just too much.

the Merc 190 was one hell of an indistructable Merc... Hope that the electronics in this case wont ruin its reliability! I know a garage who have been running a fleet of 190Ds since the mid-80s, with over 300 000km, practically all of them are still going strong!

Very clever "backwards compatible" trick, they make this concept seem so cool, that lots of people will want this on their oldies, now they will sell a bundle of these motors to people wanting the transplant, prob. not only on mercs either, and make a killing in supplying fully built engines for a demand they created, thus lifting their spares divison's incomes, as well as their suppliers'.Nice one merc.- clever marketing! ps. Looks like a R8 ;)

Like the idea...retaining the classic looks and solidity with a fresher and more efficient heart...although I'd still want a 190 with all its original parts :)

I hope they will show better progress pictures, how they build it, with a list of everything needing changing. There are plenty of people that think W124 and W201 Mercs being the best built cars in the world, including the modern ones. I have one W201 2.5D standing beside the garage and one E28 BMW behind it, waiting for BMW S-engine transplant :)

how economical will that be? Presumably even better than the C250. The classic looks and modern engine combination are pretty appealing- I want one.
