We know that the Nissan GT-R's ECU wizardry is impressive, but this little tidbit left us in awe. According to our friends over at the GTChannel, the GT-R's integrated computer limits the vehicle's speed in Japan to 111 mph (180 km/h), but once the GPS system detects that you've arrived at a domestic circuit, it removes the top speed limiter for all-out track assaults.

In the U.S., they've bumped up the electronically-limited top speed to 156 mph (250 km/h), but there's no integration with the GPS here in the States, meaning that anyone that wants to go faster on track has to have the ECU modifed. Nissan has made several overtures that the GT-R's ECU will be a tough nut to crack, but we're sure that enterprising tuners both here and abroad will be able to coax a few extra ponies out of the twin-turbo'd 3.8-liter mill and remove any electronic nannies that go with it.

      Dear Nissan,

      Be serious, please. If its the law in Japan to limit the top end, that's fine. But I would warn you, Porsches and Corvettes are NOT governed in North America.

      That ecu function was a source of paranoia for some makes and years (all while not happening.) Here it is out loud. Hmmm.
      • 7 Years Ago
      Boys, 50 years ago we ran old bias tires that came apart at 75 MPH. that didn't stop us from running hotrods up to and over 120 MPH. Sounds tame today, but back then we had king pin front ends, drum brakes all round, and power steering was "that new stuff". Bonus- the suspension would let you reach out the side window in a sharp corner at speed and palm slap the pavement. Seat belts? Air bags? You gotta' be kiddn'.
        • 7 Years Ago
        True, true... my mom has stories about once going 160mph on a public road with a then-boyfriend who was a cop. And that was in an area which had mostly dirt roads until the 1980s (and still has a good number of dirt roads today).

      I fail to see a person's logic purchasing a 200 mph street vehicle when they are not permitted to exceed 75 mph in the United States.

      Would it not be a better idea to spend less on a capable street vehicle and purchase a dedicated track vehicle instead? Why race a vehicle with performance degrading, air conditioning, leather seats, full carpeting, sound insulation, 12 speaker audio systems.......?

        • 7 Years Ago
        That is the joy of freedom. You can buy what you want. The great part about this car and the ZR-1 is that you can drive it to the track, on the track, and back home. Speeding is against the law, but that is the choice of the owner of the car and how fast that person would like to lose their license. I would not want to be limited how fast I drive by a computer nanny. I do believe that no one should test the top speeds of these cars outside a track environment though.

        Can you imagine cars being electronically limited to a maximum top speed of the speed limit? Police agencies would lose so much revenue and movies would be really boring!!
        • 7 Years Ago
        Well I guess you could buy a track car, commuter car, truck and trailer to tow the track car to the track.
        • 7 Years Ago
        Edsel -

        It sounds like you're on the wrong site...
      • 7 Years Ago
      People with the Japan version will have no problem hacking this. Even I could do it if I didn't mind the GPS being stuck in one position when I wanted to go fast. Make a dongle that feeds the coordinates of a track to the computer and the limiter would be off anywhere you wanted it to.

      The American version sounds a little tougher though.
      • 7 Years Ago
      What kind of 'supercar' has an electronic speed limiter? I'm in awe, as to how dumb Nissan is.
        • 7 Years Ago
        Road cars made by the major automakers in Germany are limited by a "gentlemen's agreement" to 155mph. That means that the CL55 or M5 you see in the showroom is crippled by design. I don't think Porsche is in that group of automakers though.

        Of course this isn't a law so it's not particularly well-enforced. Clarkson pushed an M5 wagon to 175mph in a recent runway test for Top Gear.
        • 7 Years Ago
        How about telling that to the folks who created the upcoming Audi RS6? It might not be a supercar but it's definitely a superwagon.
        • 7 Years Ago
        It ain't a supercar, 156mph is laughable now a days.
        Do Porsches have limits? Sure it can be modified, all other cars can be modified and tuned.
        • 7 Years Ago
        So its more lawsuit happy in Japan where its limited to 111mph instead of 156 in the states? Its not like this car isnt designed to handle that kind of speed, not that any speed over 90 is usable on the freeway. I just think a halo car such as this should not be limited. Some cars are limited because they become unstable at higher speeds. This is not one of those cars. Maybe the Veyron should have a limiter on it.
        • 7 Years Ago
        captainslow, thanks for proving my point, on that level go F yourself.

        Matt, I would say people buying Porsches, Ferraris and Lambos are not the most capable considering the # that get wrecked every year. Anyone buying an $80,000 car or $120,000 or $200,000 can afford driving lessons and track time. You or who ever you hit are just as dead at 150mph than 190mph.
        • 7 Years Ago
        It's not that nissan is being dumb by limiting the car, it is more like they are being smart. They realize that this is a very powerful car and is very cheap compared to cars with similar performance. They understand that this car will therefore get into the hands of less than capable drivers, who will crash it trying to hit it's near 200mph(non limited) top speed. So they limit it to places that aren't tracks to prevent them from hurting themselves or others in an uncontrolled environment. They do this in the US because the same thing will happen here, and since this car's major market is Japan they haven't fixed the car to recognize US tracks, which is also why the limit is at 156 instead of 111(so Americans can use it at the track and not be hampered 90% of the time)
        • 7 Years Ago
        thanks for making my point
        • 7 Years Ago
        Wow, smart comment-I live in the US. The replies just continue to prove the point. Pathetic.
        • 7 Years Ago
        The Veyron does have a limiter on it, its just set to 253 as thats how fast the tires are rated to go safely.

        The German cars probably have limiters on because they have some of the only roads in the world where you can (and are allowed to) reach those sorts of speeds. While the engines can do those top speeds, it probably puts far more strain on the engine and transmission than is wise, so they limit it just for safety.
        • 7 Years Ago
        relax man. you made a stupid comment, just accept it
        • 7 Years Ago
        Rob, you're an idiot.
        • 7 Years Ago
        Wow, smart comment - its the law in Japan
        • 7 Years Ago
        It's because you live in lawsuit-happy ol' USA that they have the limiter.

        "Oh no, my car went off the road at 175mph, it's Nissan's fault because I can't drive! Sue sue sue!"
      • 7 Years Ago
      A simple method to drop the number of deaths in vehicle accidents caused by excessive speed would be for the not so bright Fed's to apply the same idea to all vehicles with GPS.
        • 7 Years Ago
        "excessive speed" doesn't mean over 156mph. It's easy to outdrive the conditions at a mere 150mph, it doesn't require being at 157.

        And furthermore, R&T did a small investigation of accidents in which "excessive speed" was considered a factor and upon reviewing the reports, there was absolutely no evidence of excessive speed in almost all of them.
      • 7 Years Ago
      Haha, nice, a 350Z tops out at 159 with a limiter on. Of course, it'd be dumb to go that fast on a public road, but it's still funny that a Z can pull past a GT-R in a top speed run.
        • 7 Years Ago
        I know what you're saying, I just meant it was funny that the gt-r is more restricted than a z.
      • 7 Years Ago
      What track can handle 150+ mph? Sounds like a boring track if there's so much space you can run up to 150.
        • 7 Years Ago
        Suzuka to name one - It won't take it long to get to 150. Yea, slow corners and low speeds are the best - not.
      • 7 Years Ago
      think about it......it accelerates 0-60 in 3.3, but yet tops out at 156. And it weights 2+ tons. Am I the only one to think that this could be a gearing issue? Such a heavy car should not accelerate so fast, and if it does, the gearing is reallllly fast. And if the gearings fast, it tops out early. my 2 cents.
        • 7 Years Ago
        @why not the LS2/LS7?:
        Why, oh why are you debating this still? My original post said 480whp, your original rebuttal stated "470 or so". Now you post the correct article stating 475. Since we're splitting hairs, were both initially off by 5hp... a fact which I already knew, btw. I rounded up to 480 on purpose... debating fractions of percentage in hp on a dyno is pointless. I guess I just liked how 480 sounded. lol. You're not any more right than I was.
        There's really no point to this actually. I don't expect you to love the GT-R, or agree with anything I say about it. If debating fractions and nit picking other people's posts make you happy, go right ahead. But it's kinda silly now. I come here because I love the cars, not to pick a fight. I dare anyone to find any post with me hating on ANY car here. The cars I'm not interested in or don't like, I don't even read the articles, let alone post a comment on them.
        • 7 Years Ago
        That's 480BHP, thank you. Even the suspect dyno plots posted give it a "mere" 470WHP or so.
        • 7 Years Ago
        why not the LS2/LS7?:
        Here you go again... lol. You use this place to vent ur GT-R frustrations. God help anyone who likes it. I use a Dynapack Dyno all the time, up to last week where my daily driven G35x put down 255whp, and my Evo IX belted out 502whp. I don't know of any Dynapack that gives flywheel horsepower. It says flywheel hp but that's just a software glitch... if you told it to say lug nut hp, that's what it would read. But I'll clear up any misconceptions for good when I put my own GT-R on the dyno. Till then, believe what u want.
      • 7 Years Ago
      This is impressive technology. Sure this car plays with the big boys in the supercar league performance wise, but it's still a GT in essence. The electronically limited top speed is not surprising. Even the $185k Mercedes SL65 AMG and $100+k BMW M6 is limited to 155mph. I suppose they're lame cars as well. And almost every JDM car is limited to 180kph, so no surprises there either.
      Just like all the BMW and Mercedes tuners figured out how to disable the limiters on those cars, GT-R tuners will do the same here. Nothing to cry over really. And these same people complaining a few weeks ago about the guys doing 200mph on the street in a Murcielago are bashing Nissan for limiting the GT-R's top speed on the street... hilarious. Keep the stupid comments coming guys... damn hypocrites. I can be guaranteed a laugh every time.
        • 7 Years Ago
        why not the LS2/LS7?:
        Did I step on your toes here? MY comments about being hypocritical has nothing to do with Geography... I made reference to those two German cars just to show that there are speed governors on other high performance machines, German or otherwise.
        The hypocrites I'm criticizing are the likes of those who were complaining about the guys doing 200mph in the Murcielago, but now they're bashing Nissan for limiting the GT-R's performance on the street. That is hypocritical by any definition. If you fall into that category... and I suspect you do based on your rebuttal... wipe your tears. I'm just stating the obvious. Don't try to deflect the issue, trying to turn it into a German vs Japan argument.
        People are entitled to their opinions... and you have the nerve to accuse me of "crapping on people" who disagree with me? I never made any comments to disagree with... except this one. And guess what? You're the only one who has. Just like you've disagreed with about a dozen other comments on this blog alone. It's you who seems to get off crapping on other people. Disagree with me if you like, but the shoe doesn't fit. You should be trying it on yourself.
        • 7 Years Ago
        You took the words right out of my mouth...
        • 7 Years Ago
        Your post spends an entire paragraph explaining how German cars are limited too so why are people complaining a Japanese one is. So of course I assumed that's what the summary sentence was about. If I was wrong I am sorry.

        For the record, I didn't complain about the 200mph Murci.
        • 7 Years Ago
        Hypocrites how?

        You apply that word capriciously. Did you hear anyone on here saying this was bad because it's Japanese but it's okay for Europeans? Nope.

        You just want to crap on people for disagreeing with you and so you ascribe certain views to other people so you can rail against them.

        Any company that wants to say their car is a supercar needs to have no limiter. AMGs limiter is optional in Europe. It's not present on the SLR at all.

        Nissan should get rid of this nanny crap. Yes, it won't come into play for most drivers, but then again most drivers don't but cars of the level of performance of this one.

        I really suspect there's more to this story than we're hearing here. One track that does need speeds over 111mph or even 150mph is the N-Ring, and either Nissan has been modding cars for the magazines to test or the limiter has more than just Japanese exceptions programmed in.

      They have higher speed rated tires. (pirelli and continental)
