VW announces new 2.0 TDI engines with Hybrid tech & power increases

We've seen various initiatives by VW to shrug off its diesel gate scam most of which didn't even have the word diesel in it.

The word ‘diesel’ is probably taboo at Volkswagen and for good reason, as the cheating emissions scandal is still fresh. However, the automaker won’t let oil burners die just yet.

In fact, they have presented their first-ever 2.0-liter TDI with a mild hybrid system. Detailed during the Vienna Motor Symposium, the powertrain will eventually make it into series production.

The EA288 Evo, as it is named, has a 12V belt starter-generator and a lithium-ion battery. This “reduces fuel consumption and increases comfort”, according to Volkswagen, which adds that the SCR components and diesel particulate filter have been re-dimensioned and improved. Also, the turbocharger now responds quicker, but, more importantly, the CO2 emissions have dropped by up to 10 g/km compared to the previous generation.

Volkswagen hasn’t cut down on power; in fact, this has increased by up to 9 percent. The output of the mild hybrid 2.0 TDI ranges between 136PS (134hp / 100kW) and 204PS (201hp / 150kW). And that’s not all, because engineers managed to reduce frictional and heat losses and to shave some weight from the engine.

Audi will be the first brand within the Volkswagen Group to get the reworked four-cylinder diesel. The automaker will use it in vehicles with longitudinally installed drivetrains, but it will eventually be adopted by other brands and be mounted transversely in some models underpinned by the MQB platform.

re: VW announces new 2.0 TDI engines with Hybrid tech & power increases

Is this same as the ones they had announced in new golf? Found some details about that in the following article, but otherwise very little info on the exact technology they are referring to.

But engine cut off and coasting using electric motor idea seems interesting.

Quote:
The eighth generation of Golf will be fitted with a 48-V belt-integrated starter generator and a 48-V battery that would complement the existing combustion engine. That means the new Golf would be alternately powered by other fuel or by electricity, as this system would allow for coasting with the engine switched off.

The hybrid is capable of recuperating braking energy, and stores the power in a 48-V lithium-ion battery. According to VW, the fuel consumption rating of the future Golf, when the system is switched on, is of 0.3 liters of per 100 kilometers. That’s over 780 miles per gallon.

re: VW announces new 2.0 TDI engines with Hybrid tech & power increases

This article: Volkswagen’s Decision To Not Offer A Mass-Market e-Golf, Focus On 48V Hybrid Instead, Raises Questions clears many questions about the new 2018 Golf Hybrid, and why the all-electric e-Golf is not being continued by VW.

In India, Maruti's home-grown SHVS system uses a similar (but 12V only) setup, using a starter-generator connected to the engine by a belt; however, it does not supply torque to drive the vehicle with the IC engine switched off, or when moving off from a standstill as the VW system does.

The 48-V mild hybrid makes it possible to ‘coast’ with the combustion engine completely switched off, thereby saving up to 0.3 liters of fuel over 100 kilometers. Moreover, this mild-hybrid solution offers much improved dynamics and convenience as a result of providing an electric boost upon start-up.

I think not. The Hybrid golf that has currently been introduced runs on a 1.5 turbo petrol engine. Additionally VW has plans to introduce about 300 variants of hybrid engines.

As the plans mentioned in the link are stated to be around 4 years away to production, it would be difficult to state which engine would actually make into the Golf although the link states a slightly varying spec to the ones mentioned in the 2.0 TDI. Maybe the 2.0 TDI would go onto it at some point in time.
