Hyundai Shows Off 460 HP Prototype Supercharged Tau V8

Coming from BimmerMike, wow I'd say watch out!

I just want to know, where's the outrage? Give me a break. If this were GM/Ford/Chrysler, every last environmental whackjob on the face of the planet would be whining & complaining and calling for the death of the Big3. Now that an Asian company does it (along with Toyota), it's awesome and cool again.


Good for Hyundai, build powertrains that people REALLY want, even if its politically incorrect. Im seriously here, Kudos to them for really making a massive effort in the past few years. Lord knows GM has done the same but no one recognizes it.


As for the economy gains... somehow I am a bit skeptical (same engine with forced induction USUALLY means poorer fuel economy) but maybe they've played a few engine management tricks to get better numbers. Usually the boost in fuel economy is "a turbo DI V6 that gets the power of a V8 but economy of an economical V6".

Awesome point and I totally agree. At Chicago, the Tundra was one of the major focus of Toyota. Glad this wasn't Ford, every activist would have lost their minds.

greenplease,

you're aboslutely correct, however a transmission change would need to be made (and most times it isnt). THere's thousands of variables to consider in such calculations, Im not saying one or the other... but "in general" is the case Im referring to.

GreenPlease...deactivating cylindars under boost probably wouldnt occur. I'm assuming you mean under full boost (aka foot planted to floor) in which case you would want all cylindars activated.

However if you mean when you just got off the pedal and the boost is still high...I also believe the cylindars wont diactivate. There will more than likly be a saftey setting of around 3psi of boost where the cyl deactiviation will be allowed to take place. This is a roots type blower so there wont be any lag and boost will not be all that high as you would find in a vortec style supercharger. Anticipate the cylindar deactivation to occur only when crusing at a constant speed.

Another aspect of this cylidar diactivation is the inverse...cylindar activiation. As the accelerator is depressed, the computer figures how much power the driver truly wants and only activates the necessary amount of cylindars...a little similar to ETC(electronic throttle control) nowadays...just applied to cylindars.

The question I would like answered is will they use this aspect in the Tau?

As to your your statment of efficency...there are few minor tweeks I'd like to address. In this case I believe the cylindar deactiviation and not the supercharger are causing the fuel efficiency gain. There are factors such as parasitic drag loss (which you mentioned) and thermal inefficancy (both of which are highly prevelant in a roots type blower...even with an intercooler)which would actually lead to less efficiency.

Also you have to look at the AFR. When boosting you are compressing air. So when it fills the cylindar it is at a greater density than standard amibient 1 atm. This requires the engine to inject MORE fuel to maintain the optimal 14.7 to 1 AFR. So in essence when you boost you actually use more fuel.

This is why turbocharged cars get far worse MPG (with the exception of diesels...but thats because of the fuel itself) than an NA car.

However the bright side...Much more HP :-)

Man, at this rate Hyundai will have their own supercar in a few years.

"hyundai" means in Korean "ambitious"

Now a Hyundai hybrid please, and a plug-in one following.

Oh, I just wanted to say something matching the context. As long as they make decent cars I don't care what Hyundai really means, it may even translate to "an elephant crapped its pants".

Nice move. More power and efficiency, I like it. Drop that baby in a Genesis and I'm SOLD!!!!

Should put that thing in the Genesis Coupe.

This will be in the new Hyundai flagship ( I can't remember the name lol)
