1.6 dCi/CDTi - are they the same engine?

ltdslipdiff

Ok, so I know Opel/Renault/Nissan/Fiat/Merc share this engine in the LCV range. However, the newest Insignia has a 1.6 CDTi which according to Wikipedia was developed by Opel in Germany and has no mention of it being a shared powerplant with the Nissan/Renault family. It boasts of loads of market-leading technological advances and patents etc etc. But is it the same unit? Now that Peugeot has acquired the Opel/Vauxhall arm of GM, does that mean that Peugeot will start using it too? Are we getting to the stage where there will only be x-amount of particular powerplants (more-so diesel) that you'll be able to chose from? On paper it looks like an identical unit to the dCi one,but not even a deep Google search can give me the definitive answer!

An Opel mechanics that can confirm my suspicions?

I never heard of engine sharing between Renault and Fiat or GM. What LCV shares this engine? I think that the engines are only shared between Renault/Nissan and Mercedes

The Fiat Talento is basically a Nissan NV/Trafic/Vivaro sharing everything but names.

I'm convinced that the 1.6 is now being rolled out across the Opel range (in the new Zafira since 2014) slowly replacing the older JTD unit.....

No, these are unrelated AFAIK

And the Renault engine was used in the Vitara 1.9 also in its earlier version and the 1.5 dCi was used in Jimnys on the continent. Suzuki are partly GM/Fiat owned too?

I'd have thought that too Colm, but given the amount of platform/engine sharing going on, surely Opel didn't go out and invest millions in developing a new engine given they were using this engine in the Vivaro's already and would have all the parts in stock for servicing etc. Also, the bore,stroke,cc's power outputs (single and twin turbo's etc) all match the dCi unit.

I think the Insignia B uses a B16DTH, which is one of these: https://en.wikipedia.org/wiki/GM_Medium_Diesel_engine

Seems to be an Opel in-house design.

The LCVs are pure badge engineering, I don't think any Opel/GM technology goes into them. But the new Vivaro (next year?) is based on the Citroen Jumpy/Peugeot Expert/Toyota ProAce, as the Renault deal has ended with the PSA buyout.

Last time I checked, Suzuki were using PSA diesels, but maybe it's Renault now? GM own 3% (or less?) of shares in Suzuki. Nissan have more of an interest in them these days, as Suzuki produce badge-engineered kei cars/trucks for them, and also the Nissan Pixo which we saw (a rebadged Indian-built Alto).

The 1.6 diesel engine found in the likes of the Astra, Insignia, etc is an inhouse GM made engine. It's not shared with any other manufacturer. The 1.6 diesel found in some of GM's commercials are badge engineered with the likes of Renault, Nissan etc who supply the mechanicals and bodies. These commercial vehicles are all made in the same factory but just have different badges put on them.

Ok I think that I’ve accepted the GM-Opel unit is not the same as the dCi unit,but I do suspect that there was some reverse engineering at play with GM when they developed their 1.6 cdti version.

Not sure why you’d assume that.

Absolutely no trace anywhere on the web of any kind of joint venture between the two and built in different plants. Are you withholding some info from me Colm?

Do you know more?

colm_mcm

No, I’m saying I’m not sure why you’d assume there was some copying going on

They have the same cc fair enough, but bore and stroke are different.

Indeed they are, maybe it’s the sceptic in me, too similar to be a coincidence with twin turbo set ups etc. But who knows for sure?

GM had an agreement to sell rebadged Renault/Nissan commercial vehicles for well over 10 years. It never included supplying diesel engines for any other use in GM products as they already had an agreement to modify engines from Fiat which were eventually replaced by in house engines.

The new one was sort-of developed with Fiat.

The most universal 1.6TD is probably the PSA DV6 in 16 and 8 valve guise.
Its in most cars from the mid 2000's and many vans.
Manufacturers have realised that a common rail 1.6 Diesel has enough power and torque to power pretty much most small to medium vehicles without problems.
Honda have a 1.6 IDTEC and a 1.5 for other markets does that make it a shared engine? I don't think so only the capacity that is the same and the same engine in different states of tune make from 100ps to 160ps.
