In an interesting development earlier this week Mercedes-Benz announced their rather odd DiesOtto engine. A petrol powered engine that uses diesel technology, the DiesOtto is quite unique.
The DiesOtto is a 1.8-litre four cylinder engine that features direct petrol injection, turbo-charging, variable compression and controlled auto ignition which MB describe as a “highly efficient combustion process similar to that of a diesel”.
The by-product of this wizardry is 177Kw and 399Nm all from an engine that is said to use less than 6 L/100km! The really interesting part is that this level of economy wasn’t achieved in a small MB passenger car like the C-Class but in a vehicle around the size of the current S-Class…
Mercedes have also confirmed that they are giving their attention to a full hybrid option for their diesel and petrol vehicles. At least these will be hybrids with a bit of a spring in their step.
The days of standing in that oily patch of diesel at the service station may be drawing to a close for consumers looking for diesel economy and efficiency without the mess.

That’s excellent! I hope that MB brings this engine to market quickly ~ it will most certainly spurr on rivals like Toyota to do better in the mileage game. We’ve had the horsepower wars, now let the mpg or km/L games begin!
I’m a big fan of diesels, in particular todays high power high efficiency types, so a petrol engine that offers the benefits
normally associated with a diesel is a step in the right direction.
Although, unless it results in a more refined engine with perhaps an improved ability to rev it is sort of pointless in some ways…ie why bother if the DiesOtto does not offer some form of benefit over a normal diesel powered engine.
