Hyundai is preparing to launch its all-new Equus sedan in regions outside of the U.S., but it appears some of the big sedan’s parts will make it State-side in the Genesis sedan. Although the Genesis just launched with Hyundai’s new 4.6L Tau V8, the Korean automaker is reportedly working on a larger 5.0L version of the new powerplant for U.S. consumption.
According to Motor Trend, Hyundai engineers are currently working on a 5.0L version of the Tau used in the Equus for use in the North American market. However, fuel economy will determine if the new engine will ultimately get the green light for the North American market. The Korean automaker has set an internal goal of 17/25 mpg city/highway – which matches the 4.6L Genesis – and is trying to achieve that goal through the use of direct injection. Once development is complete, the new engine will likely have between 400 and 420 horsepower.
Of note, Hyundai also has a 5.5L version of the Tau in its arsenal, but has deemed that engine to thirsty for North America.
It has also been rumored that Hyundai is working on forced induction versions of its Tau V8, which could be applied to 4.6L and 5.0L versions.
No word on when the new engine could hit the market.

Wow lots of hp, but gas mileage? I’d stick with Ford Ecoboost instead.

I’m glad North America has become the poster child for restraint. I’d hate to see what the Triple Whopper would look like if Burger King really let fly.

Hyundai just keeps biting off more than it can chew. It should really try to sell the Azeras & Geneses first before jumping the gun.

The Genesis really is impressive. However,I have already seen 0.9% financing on the Genesis V6. Incentivized rates already? It is a crowded car market. And I’m in Houston with the oil boom. Hell, I even saw $12,000 off MSRP of the Audi A8. If you judged by the Olympics commercials you’d think that Audi could set any price it wants.

I thought the trend in engine development was towards smaller more fuel efficient units? Here someone goes again making an even bigger V8. I doubt we’ll ever see it here.

its not the same team that made the excel tho. the hyundai team now has all the top designers from ford, gm, & vw. the team thats responsible for the NEWEST caddy CTS is working for Kia. Peter schreyer thats responsible for the new beetle, audi tt, GTI, a3, a8, a4, & a5 is working for both hyundai & kia & is solely responsible for the soul, koup, knd4, & kee concepts… hyundai & kia have got it together.

Cool. I hope this works out. 400-420HP from a 5.0L means that they will out do Infiniti’s 390HP 5.0L, and possiblely beat last-gen BMW M5’s 400HP from their 5.0L. Me likes horsepower.

Their 5.5L which is suppost to be more than 420hp. I bet YO that then can’t top 0-60 under 5.1 second. I think the Horsepower is just a scam…..

In regards to forced induction, the Tau V8 was designed for it from the beginning. In these times where gas prices are unpredictable (right now, they’re low – under $2.00 per gallon for regular in West Palm Beach, Florida), it’s probably not a great idea to have something too thirsty.. However, Hyundai is obviously prepared for whatever BMW or Mercedes throws out there…
