Even with two completely redesigned models debuting in the coming weeks, Hyundai won't leave its carryover models alone for the 2010 model year. Engineers have tweaked the 4.6-liter V8 in the Genesis sedan and extracted an extra ten horsepower from the Tau to bring peak output up to 385 hp at 6,500 rpm.

Hyundai Technical Center powertrain director John Juriga acknowledged that the performance stats will remain the same, but drivers will be able to feel the increased grunt. The revisions not only increase output, but also improve the refinement and driveability of the V8 to feel more responsive at the low end of the tach.

To achieve its goals, Hyundai added a two-step variable induction system that varies the flow through the intake manifold at low and high rpm, along with continuously variable valve timing on both intake and exhaust, larger valves, and a chromium nitride coating on the pistons to reduce friction. The updated Genesis sedans will be arriving in dealerships later this year.

      OMG after 2009, it must be 1950!

      What crackpot gives a damn about horsepower in 2010!
      Where's your high MPG engines.

        My Accent gets 40mpg on the highway and competes very well for its class in auto-x. Shut up.
        • 5 Years Ago
        Wow Matt, he much bigger Taurus SHO gets 3 less HP and gets the same MPG... but that just goes right over your head I guess.
        • 5 Years Ago
        WTF are you talking about?
        • 5 Years Ago
        Uhh, how 'bout Hyundai's new DI 4 cyl which likely will push the Sonata's listed MPG up to over 35 MPG?

        Besides, for a V8, the Genesis w/ the Tau engine does pretty well w/ regard to highway fuel use - there have been owners getting 31/32 MPG going 71-72.

        And yet there's always a troll or two in every crowd, especially in forms relating to Hyundai. THis being probably the most retarded anti-Hyundai comments yet.

        Let me just add, Peak Oil may hit us in 2020, so, you're right no need to Rush to Prepare for it. Let's stay Unprepared for the Next Nine Years.

        I do...I could care less about silly MPGs...but on that front...Hyundai's 385 HP V8 is just as economical as a 3.5 V6 from Ford.

        So...I 'll take the proper V8...and let you to drive some POS rollerskate.
        • 5 Years Ago
        some get rid of that fool Mike....if you want something with mpg, get a chevy that drives boringly down the road....at least some other manufacturers are letting the last of us gear heads have some fun (yes i'm aware of the corvette and maro ss, so save it with the comments )
        • 5 Years Ago
        If you can get people to stop buying them, I'm sure auto manufacturers will stop making them, but until then V8's will still be around. I think your argument falls on deaf ears here, especially when you bring up politics. Perhaps you should try http://green.autoblog.com.

      I love that Hyundai continues to better themselves...this is not a bash or in any way a negative comment towards the company....BUT

      "Hyundai Technical Center powertrain director John Juriga acknowledged that the performance stats will remain the same, but drivers will be able to feel the increased grunt."-Can anyone really feel 10 extra horsepower?
      • 5 Years Ago
      This is the kind of continuous refinement I like to see.
      Honda, are you listening ([cough] INSIGHT [/cough])?

      Great job Hyundai.

      Most companies need to learn by this example, which is once you got a hot product, don't just sit on it and wait for other manufacturers to come out with something better. I myself follow that example for my business.

      As for the technology Hyundai has put into this V8, I definitely congratulate them for their efforts, teamwork, and strides to bring the company that once was rubble to becoming one of the manufacturing leaders showing others how a successful business should be ran.

      Keep up the great work

        I am very impressed.

        I have been saying this for years.......This is why I can't stand GM.

        why is it that some car companies like Hyundai and Ford, can get this much horsepower out of such a small engine, but GM has to have a monster 6.2 liter, which is what like 390 cubic inches, to get 426 horsepwer, which is only 30 hp more that this tiny 4.6 liter engine.

        Its like GM has to rely on bigger and bigger engines, not to be funny, but its like GM is literally making up for something. It's like they can't be competitive without putting monster sized engines in their cars.

      Nice. I would like the Genesis if it didn't look like other cars combined but instead had it own personality.

        • 5 Years Ago
        @JDM Life
        Guess you don't like the Accord or Legacy either.
      • 5 Years Ago
      I wonder what the torque increase is. 385hp is hugely impressive from a 4.6L V8, however the current car gets by with only 333lb-ft, which isn't anything special from an engine this size.
        • 5 Years Ago
        Maybe 333ft-lbs is now on regular?
        It used to be 375hp 333ft-lbs on premium 368hp, 324ft-lbs on regular.

      I'd be terrified of Hyundai as an automaker.
      • 5 Years Ago
      all they need it to do is direct inject it like their forthcoming 4-pot

      @Purplewon Hyundai wanted to develop a luxury line but it would require a heavy finacial investment upfront (somewhere in the area of 500M or more maybe to start a brand) and that would be risky. It was a smart move that they didnt because shortly after the Genesis launched the economy went up in flames lol. They would have had a hard time supporting a luxury brand with only one car in a down-turned economy.

      385...not bad, hyundai, not bad
      • 5 Years Ago
      Hyundai is certainly not sitting back and resting on their laurels. They continue to improve year after year after year. Most people don't want to admit it but the Genesis is a very capable vehicle that easily competes with in the luxury arena. Once the Equus comes around, there's going to be very little question that Hyundai cannot stand side by side with the likes of Mercedes, BMW, Lexus, Audi and others.. It's a shame to see how quickly they're excelling into "top tier" status while our own domestic luxury automobile companies fall further into the unknown...
