We don't imagine that many new-car buyers are cross-shopping their local Infiniti and Porsche dealerships, but there's at least one segment of the automotive industry where the two automakers both play ball: high-performance hybrid luxury sedans, which may be the single most conflicted niche of the automotive sphere in the known universe.

In any case, here we are with the Infiniti M35h and Porsche Panamera S Hybrid. Each one is marketed as both a somewhat greener luxury vehicle and a performance sedan. We'd guess it's the performance side of the equation that would be most interesting to the majority of buyers, leaving fuel efficiency a welcome bonus.

So, which one is faster? That's an interesting question. Usually, we equate that term with top speed, as "fast" connotes velocity. When acceleration is being contested, we generally ask which machine is quickest. And, if it's quickness you're after, Infiniti wants you to know that its M35h will out-accelerate its competitor from Germany. How quick is it? According to Motor Trend, the hybrid M goes from 0-60 in 5.1 seconds, but that's not the stat Infiniti is claiming. According to the post-jump press release, the M35h is "faster" than the hybrid Panamera from 0-100 (11.54 seconds) and in the quarter mile (13.41 seconds).

As for the rest of the relevant statistics, the EPA estimates that the M35h will manage 27 miles per gallon in the city and 32 on the highway, for a combined rating of 29. The Porsche Panamera S Hybrid is rated at 22 city, 30 highway and 25 combined. Seems the M hybrid takes both the acceleration and economy awards. Check out a video released by Infiniti after the break, where you'll also find the press release, if you're into that kind of thing.

Infiniti Presents World's Fastest Full Hybrid: The Duel

– The 2012 Infiniti M Hybrid races against the 2012 Porsche Panamera S Hybrid –

FRANKLIN, Tenn. (Jan. 23, 2012) – Once again challenging the status quo when it comes to hybrid vehicles, Infiniti today released 'The Duel' exclusively online to showcase the power of the 2012 Infiniti M Hybrid, live on Youtube.com/Infiniti.

Teased online last week, the full 90-second spot opens on the 2012 Porsche Panamera S Hybrid, which is quickly passed by the 2012 Infiniti M Hybrid, affirming the thrill of the luxury environmentally-friendly vehicle.

"'The Duel' is an exciting way to remind everyone that the Infiniti M Hybrid is the world's fastest accelerating full-hybrid with 360 horsepower and 32 miles per gallon," said Infiniti Americas Vice President Ben Poore. "At Infiniti, we believe that luxury should always thrill and inspire."

Inspiration for the video originated when the Infiniti M Hybrid made it into the Guinness World Records® as the world's fastest accelerating full-hybrid car last fall, when the 360-horsepower gas/electric luxury performance sedan covered the standing quarter mile in 13.9031 seconds (average of all runs). Infiniti secured AMCI Testing, a third-party testing firm, to substantiate the speed of both vehicles and Certified that the Infiniti M Hybrid actually was faster in its tests, covering the quarter mile faster in 13.41 seconds and accelerating from 0-100mph in 11.54 seconds.

      The Toyota TS030 begs to differ on "fastest" hybrid title heck, even the 911 GT3 R Hybrid :)

      As i said in the previous video, the Mhybrid is faster than the Panamera hybrid by atleast .5sec. We need a proper test between this two though, they are both amazing.

      Ugh, I like Porsche and generally am disappointed by Asian brands of late ('cept Hyundai/Kia) but if this is true, bravo Infiniti. I can't even say the Porsche beats it in appearance either. It looks good in a round sorta-way.

      Lol, If you drove this vehicle from the disclaimer saying 0-60 in 5.1 seconds, You assuredly would not get the 27 miles per gallon in the city and 32 on the highway it boasts in its claims. As for the hybrid Panamera and its boast of 0-100 (11.54 seconds) and in the quarter mile (13.41 seconds), There are no 100 MPH Highways in the States, and you would just be making the oil companies richer trying to drive in those parameters if there were. I can't help but wonder if Car manufactures have been, and are way off on every direction they are moving in manufacturing vehicles without any thought to economics and environment when it comes to new models. This may be why most are in trouble financially, and then beg for help of Government and tax payers to bail them out in the end.

        i take it youve never been in arizona,

        Thanks for clarifying that that when accelerating to 60 mph at full throttle, the Infiniti will not deliver the advertised fuel economy. Really f***ing insightful. Also, because there are no 100 MPH highways, you can't drive 100 mph? Grow a pair. One last point- most car companies are definitely not in financial trouble as of now. I hope to God you don't have a driver's license. Your level of stupidity and ignorance that you have so aptly displayed is proof that you shouldn't be on the road endangering the rest of us.

      13.41 1/4? That's pretty quick.

        Nah... I put a mini fusion reactor in the trunk of my Prius and now I can run 11's all day. The only thing that sucks is finding the plutonium to initiate the hydrogen based fusion.

      Who cares? It's still an Infiniti.

      Ok... and Audi vehicles are revishing and have better straight line performace and nearly the same economy from non-hybrid models. The A7 for example. Sorry to be the sceptic, but I'm still not sold on the strength of this hybrid tech as a result.
        • 3 Years Ago
        haha, I didn't proof that at all, sorry "Ok... and Audi vehicles are ravishing and have better straight line performance and nearly the same economy from non-hybrid models. The A7 for example. Sorry to be the skeptic, but I'm still not sold on the strength of this hybrid tech as a result."

      It's funny that you chose to bring up the distinction between the terms "quickest" and "fastest", because you guys mix those terms up on a regular basis.
      • 3 Years Ago
      you forgot about the Tesla S model.All electric and 0-60 in 3.6
        • 3 Years Ago
        It also doesn't exist.
      • 3 Years Ago
      I can't even tell how many Porsche buyers consider buying an Infiniti... Mostly because they don't exsist....
      • 3 Years Ago
      I love my Infiniti, but in this case I would still go with the Porsche.
