And the wishful thinking is that soon they offer the 1.8 TSI in Jetta Comfortline!

That would be a killer, and if it is priced in the range of 13-14, we have a winner !

Well the reliability will definitely tend to go up a notch. The electrical problems that plagued passat will definitely lessen. Looks like VW has adopted a strategy to try out stuff with Skoda cars and whatever is successful..implement it with VW,, It`s important for them to retain the prestige of the mother brand and avaoid a negative image like Skoda. That said, do you guys think that with the Tsi engine, the turbo lag issue of the Passat would be sorted??

Sorry for my ignorance. Does TSI have a turbo lag? I heard its only for diesel.
I know TSI is turbo charged, bit even TSI has a turbo lag issue?

It should not have a turbo lag. Tsi engines have a supercharger in addition to the turbocharger. I believe the supercharger comes into play instantly as the engine is fired up and provides the boost at lower RPMs. As the engine spools up the turbo charger takes over hence no room for the lag.

Not really, TSI engines are only turbocharged. As far as I know VW has only a 1.4L 'twin charged' engine (an award winning one at that) with both a super and a turbo charger.

will the new downtuned 2.0 crdi engine find it's way into the laura aswell? as a replacement for 1.9 PD I mean...

Cheers

You are confusing FSI with TSI

All TSI engines have both the Super Charger as well as the Turbo charger.

To bring you up to speed I have attached the TSI brochure. It uses the 1.4L for illustrations, as this is the base engine for the TSI range.

For those amongst us who are pining for the DSG gear box read what the father of TSI technology Dr. Rudolf Krebs has to say on the DSG at #9 on page 10.

Thanks for the brochure, it was interesting to read up on this particular engine.

However, the brochure is for the twin-charged engine. This concept is only available on the 1.4. The other larger engines, which have also been labeled, somewhat confusingly, TSI by VW are just turbocharged.

Please refer to the Team-bhp thread discussing this class of engines.
http://www.team-bhp.com/forum/modifi...-vw-infos.html

Also, if you read the brochure (Page 13), you will find why this technology is not useful for higher capacity engines:

"Why not apply TSI technology to larger engines for even more power and performance?
In one word – efficiency. In a few more – because there really isn’t a need for it. Larger engines usually produce enough
gas flow to enjoy efficiency and power gains from a turbocharger alone."


TSI in its general sense refers to Fuel Stratified Injection with Turbocharging.

If this was the case, why would VW give the 2.0 CRDi engine to the Superb & and Laura? Moreover, why would VW give up the DSG after its huge success in the Superb?

As far as I know the 1.8 TSi unit has both a turbocharger and a supercharger. I recall reading this in several magazines but wiki say's this:

"TSI, an acronym used by Volkswagen Group for petrol engines featuring its "twincharger" (turbocharger plus supercharger) and Fuel Stratified Injection technologies; latterly, also used for engines featuring only a turbocharger and Fuel Stratified Injection."

Now I'm confused... I clearly recall reading that it was thanks to it's twin charger it could put out max torque at as low as 1500 rpms!

As long as I dont see a lag in the engine, it is fine with me.
Jokes apart, we should see a deluge of TSI options (1.2/1.4/1.6) in the next 2 years being bombarded by VW.

For starters:

Polo 1.2 TSI (may/may not)
Yeti 1.2 TSI
Golf 1.4 TSI

Polo may not come in with TSI soon, as VW would like to keep the prices down. But it may change tactic as TSI gains mass acceptance.

[anekho]

I have a gut feeling their going to plonk the 1.2 TSi engine in the facelifted fabia that's coming out soon along with some more premium features to justify the price

I mean they have to differentiate the fabia from the polo somehow... what's the point of the same parent company (vw) having two hatches with identical specs? They probably want to differentiate them to get more mass acceptance!

All just pure speculation - let's see what really happens.

Methinks you really do have a point there. Fabia was the original premium hatch in India, that got diluted with the launch of so many around it's price range.
They might be tinkering around with the engine specs to justify the higher price.

Than that should be a detuned 1.2 TSI. Even the Yeti is planned for the 1.2TSI 100 BHP. Dont know how the two can match?

[avishar]

If they decide to plonk the 1.2 tsi engine in the fabia,give it a few more bells and whistles,and price it at around jazz territory or higher will it get buyers?
