GV80 3.5TT

[Backslack]

I don't know what Daehanminguk is talking about, but the major difference is that the 3.5TT is both port and direct injection whereas the 3.3TT is only direct injection. Korean reviewers say that the 3.5TT in the G80/GV80 uses port injection at lower speeds and launch, making it feel smoother yet more sluggish off the line than the G70 and Kia Stinger. However, recent reviews say that the GV70 (which uses the same 3.5TT) feels way faster off the line than the 80 counterparts, similar to the G70 sedan. So I think it's just a matter of different engine tuning, since the 80 series is more focused on luxury and smoothness rather than the sensation of off-the-line acceleration like the 70 series.

I pinged Terry at BMS...and they are working on the 3.5TT already

I only live 3 miles from them and am happy to loan them my car if it helps.

Do we hope the additional port injection in the 3.5t will help reduce it's valve carbon deposits?

So, you can't explain it. They would not add an ounce of weight unless it was justified with economy and/or performance. I'm sure Barney and Friends here would really like to know the details as many are very engineering oriented and love to get details.

he thought he was smart and got defensive when called out by people who actually know what they are talking about. Dont waste your time

I would think so!

That, along with a likely different transmission programming, with the shifts in the GV70 more geared to performance as opposed to being a cruiser like for the GV80.

Yes, Hyundai spent massive money to produce the new 3.5t which is solid. However, they failed to implement engine capability.

How so?

The 3.5TT offers more power while offering a little bit better fuel economy (more efficiency).

There will be a higher output variant of the 3.5TT 1st headed to the G80 Sport (remains to be seen if the GV80 will be getting a Sport variant) with around 420 hp, but the engine is capable of putting out even more power (as is the 2.5T), but then you start to get into reliability/warranty issues/costs.

And don't think they spent massive money as it's not a total clean sheet design.

It should yes. Best of both worlds I think. My G37S which was all port injected, at 50k miles when I was doing some injector wiring work and saw all my valves, they looked almost new. See picture. If Genesis can do that and improve efficiencies at the same time, bonus.

Thanks Pulsar. I miss that engine... in my prior '09 G37.
