New NSX Engine Revealed

Isn't the wheel pattern functional: aero helps induce air over the intercoolers?

.I think spinners would look better..........
 
When I first saw the new NSX I thought this back window would show the engine nicely but now that the engine wont be transverse I wonder if Honda will elongate this window to make more of the engine visible. Or will they even need to. I'm gonna see the new NSX again on Saturday....will be interesting to see if any changes have been made yet to the body. Would be really Sweet to be able to actually see the engine in the back at the show but doubtful I think.

Does anyone realize slowly but surely we have gotten everything we asked for? We started with some front engine 4 seat V10 concept that was scrapped. The car went back to mid-engine and 2 seats. We were told hybrid and everyone thought fuel miser non-trackable car. That was wrong. We wanted power and it looks like that will be there too via two turbos. We wanted it t be able to compete with a GTR, and looks like that, it will be able to do. We wanted longitudinal and it looks like that is happening too. If there is one car I really like and wanted it to be the benchmark it would have been the 458. That is also the car they precisely pegged, just like 1990 with the F355. The NSX was a responsive, visceral, reliable Ferrari fighter. And that is what we seem to be getting, AGAIN. If that doesn't excite you, you need to go have a cardiogram.

Don't worry they have it in itunes now:

In yellow no doubt. ;)

I certainly hope so. Ferrari, Lambo, etc, does it and it nicely frames the engine to an almost picturesque level. IMHO, it's a great opportunity to provide that extra finishing touch - especially for those in the target market.

I think the reason no engine was shown is because they had it under wraps.
Now that it's in the public domain we may well see a glass or plastic panel in the engine cover.
It's a nice looking driveline and well worth showing.

it will be most interesting to see how Ted and Co. design the front and rear storage areas.
That large rear clutch pack/electric motor might interfere with a regular style trunk
I've never seen a Japanese car that wouldn't hold two golf carry bags.

Exactly!
 
I am so happy Honda is going this route. I think they have a few other tricks up their sleeves for this engine. My guess will be high compression to spin the turbos quicker (11:1 +) and a new technology for the turbos rather than traditional turbochargers. For those of you that are hung up on NA power you might as well live with the new age emissions requirements. With the new requirements you cannot have the traditional high HP per liter small displacement NA engines. They are not clean enough. This is the reason for turbos. I said it a while back that a lot of manufacturers will be using turbos .

My only gripes with the car are the hybrid system and loss of sharpness on the front end. I'm not a fan of the blunt R8 type front end. Maybe I need to see it in person to appreciate it more.

I also like it better than trying to take a small engine - with little torque relative to turbocharging the same capacity - and getting "only" 400 to 450 hp.

What is it exactly about a small displacement/high-rev engine that is not emissions-compliant, yet the larger displaced (all N/A) Ferraris, Lambos, R8s can be? If bore & stroke are identical in, let's say a 3.3L V6 and a 6.6 V12, how is it that the smaller motor can't pass EPA?

Also, I wouldn't worry about rev limits. Ferrari and Porsche build turbos with 8000-9000 limit, so Honda can do it too.
Not sure where you got that info as Ferrari has had one turbo'd production car which ended over 2 decades ago, and the couple of Porsches (Turbo, GT2) don't rev anywhere near those numbers; they make peak power somewhere in the mid 6Ks, IIRC.

It does feel like they have been reading Prime and incorporating the suggestions of those most vocal here (and with the most post counts)! :tongue:
I think it's going to be at the SF Autoshow in the next few days. I need to head over there and see it with my own eyes. I would love to consider getting one.

Why do you think Honda would use an 11.1 compression ratio in a turbo application?

That's not happening. No reason why you'd want to do that unless you want to destroy longevity. Two turbos can spool fast, and with the electric motors there's probably a trick way to make that happen even faster. You throw some torque into the engine from the batteries at lower RPM, that gets the car going fast, that raises RPM's fast, that brings the turbos online fast. In fact the combining of turbos with electric motors can be really cool, though I won't play armchair engineer anymore.
 
If twin turbos and a hybrid is good enough for the mclaren p1, it's good enough for me. ;)
 
Nissan will now chase this route with the GT-R. Looks like this time Honda is ahead. As for the aftermarket they will just have to learn. Ted Klauses reply to the editor of super street about how easy will it be to modify the car was funny. A bit of silence followed up by an uncomfortable "things like aero" in other words: "please don't F with my car". :D modifying cars to an original engineer is like saying "how much salt and ketchup can I add to your food?" to a chef.

When the chef asks why you dumped a fistful of salt onto his food you say "well I wanted individualize it". LOL
 
Direct injection (DI) Engines are high compression by design, they are like Diesel engine, so the compression ratios will be high on this engine regardless if they are Turboed or not.
Another interesting bit of F1 Technology that has not been discussed, is that, Honda Engineers have the ability to spool the turbo using the Electrics on the car, so the turbos could be running at optimum range all the time - therefore No Lag.

From Csaba Csere at Car and Driver

"Compression ratios still need to be reduced in turbo engines, but when the turbo comes with a switch from port to direct fuel injection, the engine’s compression ratio is only reduced fractionally. Even when you add turbocharging to a naturally aspirated engine that already has direct fuel injection, the compression ratio might only drop from 12.0:1 to 10.5:1, as in the case of the European version of BMW’s 3.0-liter sixes. "

The new MDX 3.5 L GDI V6 non-turbo engine has an 11.5 compression ratio
If we were to assume a higher performance Honda GDI non-turbo V6 would have the same 12.0 compression ratio as the BMW, then wouldn't we expect a turboed high performance Honda V6 GDI to be around 10.5, similar to the BMW?

In any event, neither the BMW nor the Honda GDI engines, NA or turbo, have diesel-like compression ratios of 18-21:1

Interesting thought, Bram. B/c Honda is already working on the 2015 F1 engine, I wonder just how many F1 ideas and tech will make it to the NSX hybrid drivetrain and how that'll effect sales. Particularly if the partnership w/ Macca produces good/bad results.
 
I think all options are on the table, so don't rule out anything....We are going to see some great Technologies being introduced on this car, after seeing the Engine and it's layout, I for one can't wait.
 
..so we got kers/electric turbos/pneumatic valves.........all for 120k......sounds like a bargain!
