You can do it but it will have to have a very high redline and reliability/durability/NVH issues are likely to come up, fuel economy will be pretty bad. The 3.7VQ engines are very rough and thrashy in the higher rev ranges and they get poor fuel economy along with having some other issues. The power does not seem to really transmit to the pavement either as competitors with less hp generally perform very similarly or even beat them. I have not read any reviews yet on the new Hyundai V6. There are very few NA V6s putting out more then 330-350hp or coming close to 100hp per liter, most high hp ones are in the 300-306hp range. Porsche gets really big numbers from their 6cylinders in the 911, but they are flat 6s that are really expensive.

I would like to see the IC engine in the next NSX make at least 350hp, maybe a little more but I don't know if it is really necessary for it to be closer to 400hp if the car is getting an extra 100hp boost from the batteries/motors.

The 1990 NSX made 90 hp / liter and the 1999 S2000 made 120 hp / liter. Either of them had direct injection.

You don't think Honda can easily make a direct injected 3.5L V6 to put out 400 hp today? That is only 114 hp / liter.

Sure they can do it but it is not as easy getting 100hp per liter out of larger V6s or making a 3.5 get 400hp especially when you have to take into account stricter emissions, avoiding poor fuel economy, and durability, NVH, etc that will go with having such a high strung engine. With the S2000, Honda was already getting 200hp out of 4 cylinders so getting an extra 40 was not as big, some complained about the lack of torque and having to rev it so much to get the power. Getting 400hp out of a 3.5 means trying to extract an extra 95hp out of what they have now. DI helps but it won't help that much. With the hybrid set up they won't have to stress the IC engine as much to get the hp and performance and they are going for good fuel economy which will be hard to achieve with 100+hp per liter. If it was that easy to get 400hp from a NA V6, more companies would be doing it, getting 400hp from a regular V8 has not even been occurring that long with most companies.

I am not really a huge fan of using a hybrid set up though as it adds weight, complexity, cost, and will most likely affect the purity/interaction of the car and driver.

God forbid they try to get another 95hp out of the current J-series. The engine was great when it debut in 1996, but the design is so old that trying to get more power out of it would mean your fuel expenditure may jump up quite a bit.

How will the new engine fare? Not sure, but I have no doubt the current technology can support a 400 hp V6. There is nothing wrong with a high revving engine. Yes it can translate into more wear, but if the engine was built to withstand it, then I have no problem with a high redline. Honda has shown they can combine reliability and high stung motors in a road car. They showcased that in the S2000. The NSX doesn't need to rev to 9000RPM, but I would be happy with only 8000. Honda engines sound fantastic when they rev

it does nothing to me if it indeed comes as a gas-electro hybrid. people don't spend 100k on a freaking car worrying about gas prices. i don't get all the 6 figure cars with hybrid system, it'll just take the joy our of the driving excitement compare to plain 'ol simple gas motors. it's just too gimmicky for me.

I'm sorry but it looks too much like an Audi R8. That being said, I feel as if this second gen NSX will not be as cool or land marking as its predecessor. Seriously its as if its entirely based on an R8 or McLaren MP4.

edit: It will be cool.

When I saw this pic on Prime it had just about sold me on the new style. Aside from the original HSC, this is the only concept car that clearly shows some NA1/NA2 roots and history. IMHO, I can now see the original NSX design concept in the so called NSX 2. If I can afford on I'd like to own one someday. Depending on how good this car actually turns out to be, I would even sell my NA1. Would love to have both though.

Recent patent filings for the convertible, so it might make production.

Pics galore of the convertible. It looks sweet!

It's clearly built on an existing NSX with 252k miles. Give me the body kit!
