Turbo Diesels how far can they go

G`day Bruce,
I`m waiting for the new 0.2 TD intercooled Whipper Snipper to come out. LOL

Plurry weeds !

Scrubby.

I guess it's all to do with the obsession to make things lighter Bruce.

I would imagine the engine would be lighter because of the smaller capacity, and goodness knows how many high tech light alloys are in there too.

I wonder if they will last as long as an old 351 though?

I have a Mercedes 315 van with a 2.1 twin turbo pushing 2.4 tonnes empty - 115 kw and 330 nm. I think it is a fantastic motor - wish it was in my Cruiser. It eats the Cruiser off the lights, up the hills and in overtaking, and does half the fuel doing it. It is my second diesel Merc and the motor in these things do last if proper servicing is undertaken. They do NOT like bad diesel - one dose can be very costly: new injectors and pump can be around $6000. So no biofuel.

We have Mercs in our fleet with 400,000 km without the head being taken off. (I can't say the same for the other bits attached to the motor - that is where Mercedes makes their money I reckon...).

If the Kia is pushing 436 nm - that's a lot. Wonder where it comes in though - the Merc is seamless off the idle all the way to redline.

The new Disco 3.0 V6 is an interesting motor too - over 500 torks and most available half a second from prodding the throttle...

Go Diesel! Long time coming, I reckon...

Been wondering the same thing. I drove a VW Polo diesel for a few hours last week. Incredible performance for a little engine. I was wondering just how long it would last. Diesels used to last for evr and were built extra heavy. The new ones are very light, relatively.

I have never minded the Sorrento and now with this new 2.2 diesel it may just be time to look a bit more serious on flogging off one of my dinosaurs on one of these Sorrento's for Judy???? Bloody good fuel figures reportedly. I just wonder why all these KW's and NM's are only being let out of the bag recently, I am sure the knowledge was there a few years back too?

Cheers, Trevor.

When the common rail with pezoid injectors (spelling?) came out a few years ago, I remember the chief engineer from VW said 80kw/litre may be possible.

The racing audi R10 of 5.5l is putting out about 522kw, 95kw/litre, but only for short bursts.

Power needs fuel however, so wonder what the fuel consumption would be on full throttle. :o)

I am so impressed by the specs on the range of 4x4 today. I wonder how they get so much power out of them.

My V8 landcruiser only produces 151kw and 430nm - makes me wonder why I shelled so much money to get this vehicle when I could have nipped out and bought a Kia Sorento. Wait no I don't - I am happy with my cruiser.

Reckon the technology can only advance further from here and that the old adage of "you can't beat cubes" is now really a thing of the distant past :-). Advances in metallurgy, fuel management systems, engine design and greater use of boost (especially with twin and/or variable vane turbos) have largely been driven but the rapidly advancing 'peak oil' - and governments around the world but moreso in Europe demanding cleaner engines. When will the capacity / power / torque optimum be met? That's anyone's guess really and I never cease to be amazed at what each generation of engineers/physicists design/discover.

I would imagine with every new model vehicle coming out there will be an increase in power and torque. It's going to be catch up for a few manufacturers though.
Has the new Pardo got more horses then the last model?

The Europeans are the diesel front runners. A garage in Europe has way more diesel pumps than petrol because most of the cars are diesel. The Japanese are playing catch up at the moment. I have a Freelander 2 with a 2.2 diesel that has 400 nm torque and gets combined 8.5l/100km economy. Hard to beat those numbers but it looks like Kia has...a pity they dropped the low range in the Sorento though? They've turned it into a good looking pussy.
