This topic is only about 2.0 TSI, 190HP engines.

INFO 1:

• Skoda Superb III - facelift 2019

• DSG - 2019, 2020, 2021

• engines code - EA888 / DKZA (gen 3B), with Budack combustion cycle and, direct injection and multi-port injection

• Compression ratio - 11.65:1

• Fuel consumption (economy) - combined (NEDC) - 6.2 l/100 km

INFO 2:

• Skoda Superb III - facelift 2019

• DSG - 2021, 2022, 2023

• engines code - EA888 / DNNA (evo4), without Budack combustion cycle, direct injection only

• Compression ratio - 12.2:1

• Fuel consumption (economy) - combined (NEDC) - 5.7 l/100 km

From the specifications, it seems that the correct choice (related to fuel consumption) is option no. 2 (EA888 / DNNA evo4). I want to ask your opinions:

1. does evo4 consume less than the Budack engine? How is in real life? I would expect it to be the other way around.

2. what type of gearbox/corresponding code is mounted?

3. in terms of reliability, what would be the correct recommendation?

And second part of this topic, i am looking at:

INFO 3:

• Volkswagen Passat B8 - facelift 2019

• DSG - 2019, 2020

• engines code - EA888 / DKZA (gen 3B), with Budack combustion cycle and, direct injection and multi-port injection

• Compression ratio - 11.65:1

• Fuel consumption (economy) - combined (NEDC) - 6.3 l/100 km

INFO 4:

• Volkswagen Passat B8 - facelift 2019

• DSG - 2021

• engines code - EA888 / DNNA (evo4), without Budack combustion cycle, direct injection only

• Compression ratio - 12.2:1

• Combined fuel consumption (WLTP) - 7.1 l/100 km

From the specifications, it seems that 2021 evo4 consumption values according to the NEDC standard are not available, and been available WLTP ones.

1. can't understand if evo4 will consume less than the Budack engine or vice versa?

2. what type of gearbox/corresponding code is mounted?

3. same question as Skoda Superb, in terms of reliability, what would be the correct recommendation?

Thank you all, i am waiting for your professional answers with great impatience :)

Best regards!

On a run I get 50mpg+ from a DNNA.

Gearbox is a DQ381 7 speed wet clutch DSG as fitted to all 2.0 facelift auto's.

NEDC was a car on a rolling road inside a building going through a programme, so not Real World.

Even the WLTP is not real world, possible real ambient temp etc etc.

& then VW / Audi can somehow manage to get a heavier car with the same drivetrain as a Skoda / Seat get better test results / figures.

Thank you!

I hadn't heard of the Budack Cycle; after a quick search, I have found out what it is!

However, I am intrigued by the original post; if I remember correctly, indirect injection was added in order to try to prevent/reduce the coking-up of the inlet valve backs (caused by the exhaust gas circulation) which the direct injection engines suffered from.

How are the backs of the inlet valves kept clean now?

It was for economy and emissions on part throttle, Euro6 was just around the corner. Any benefit in reducing carbon build up in the ports was just a convenient side effect.

When the regulations tightened again (WLTP/RDE) and they started using GPF to control emissions, dual injection was no longer necessary.

VW Used pure magic and software on 1.5 TSI ACT,s to get the WLTP Certification.

It worked, they got the scores on the doors.

The cars run like sh!te and eventually a Safety Recall was required because of Lack of Torque, which was the Kangerooing issue.

But they sold them, supposedly fixed ones, never had to do a buy back.

Vorsprung Durch Technik. You can get away with any old crap.

Hello. What do you recommend though? Budack or evo4?

Neither. I'd base my decision on the overall car and deal rather than chasing a specific engine.

Yes I agree.

In real terms the differences in economy are small so this will be really down to finding the right car with the spec the OP wants at the right price..
