Mercedes is one of the pioneers in the field of diesel engines in passenger cars, the new TO 654 according to the Germans an important milestone in that long dieseltraditie.

Proudly informs Mercedes that she the average use of the range in the past twenty years have almost managed to halve. From an average of 9.2 l/100km in 1995 to 5.0 l/100km in the last year. The from scratch designed new tweeliter diesel, code-named TO 654, which figures to further improve.

Mercedes pulls this new block will be fully out of aluminum, according to Mercedes-Benz the first time that a four-cylinder diesel completely made from this material is*. The power source weighs only 168.4 pounds, compared to 202.8 pounds for its predecessor. The pistons are of steel, but a special Nanoslide coating the internal friction to a minimum. Also fits Mercedes an improved Common-Rail injection, the fourth generation of the brand, which was one of the first was, after the Alfa-Romeo 156 2.4 JTD.

All that nature must, of course, lower fuel consumption, ensure that succeeded. The consumption is 13 percent lower than that of its predecessor. And that while the ability of the tweeliter diesel 195 hp, where the old 2.1 it kicked up to ‘only’ 170 horses. Mercedes reports and passing, just that the engine complies with the future emissions test, the WLTP cycle. This test, which the chronically failing NEDC cycle should be replaced, need a better picture of the consumption in practice. Also the direct testing of emissions, in practice, something since dieselgate often raised, is something that Mercedes supports. Incidentally, used Mercedes-Benz called AdBlue to the emissions as low as possible, to get.

The first car that this new engine will find its way, is the Mercedes-benz E 220 d. Later, the engine will also be in the C-Class and other models the old 2.1 diesel to replace. Or the new block, also some uitvoerigen with the 1.5-litre Renault diesel will replace, want Mercedes not yet say. Perhaps they develop a variant with a smaller stroke volume in order not to depend on of the French power.

*According to a number of observant readers would Mercedes not be the first, and so with hands on heart. So would Peugeot in 1965, already an all-aluminium diesel in the 204 have spooned, while also Honda this years back already did.
