The Enzo successor 920 HP!!!

P 4/5 CM (2012) race configuration with new aero package (a lot of downforce but much less drag), developed engine, and KERS could easily run a 6:45 on the Ring that you know with qualifying tires. The one we race on is the regular Ring plus the GP course. On endurance race rubber and tune we'll run 7 minute laps on that section for 24 hours lap after lap.

Unrestricted in sprint tune, super soft tires which would last about one lap, and DRS on rear wing we'd run about 6:30.

Ferrari P 4/5 by Pininfarina would be about 10-15 seconds a lap faster than an Enzo but could also do a lot more laps than an Enzo before overheating the suspension as it's a lot lighter.

As for KERS. Pure KERS captures braking energy and converts it to electrical energy which can be called on with the push of a button. At the Ring because of the need for a lot of braking during one race lap we can recapture enough energy to produce about 60HP for 40 seconds on the straights and two 5 second push to pass boosts. On the road there won't be enough braking to produce this HP so the gas engine will produce it and while producing it will make less HP available to drive the car. Once stored it can be used but on the street it will really be more like a stored shot of NOS in that during street driving won't recapture nearly enough to charge the system. This is what the system in the new Enzo will really do in real world road conditions.

The first photograph is some of our batteries. We will use 200 of them in a engineered pack with air cooling. The inverter will be water cooled as will be the motor.

The second photo is us testing the KERS system in virtual reality using our last years race data and running the car for 24 hours at racing speed, stint length, and braking and measuring just how much energy we can recapture without boiling the batteries.

When the flag drops we'll see if we can keep up with the Porsches and other factory cars which last year were a lot faster than us. This year we'll also be up against Mc Laren GT3's. This is a very serious race and the Factories are very serious so it won't be easy.

Jim, this is great info and I really appreciate you sharing this.

1. What's your estimate for the last P 4/5 C you ran at the ring?
2. Don't you think an Enzo with super soft tires and corrected suspension would run in the low 7s? Even a Porsche GT2 RS with the same HP can do that with less downforce.
3. KERS for the street will be interesting. How does the Porsche 918 with a 550 HP V8 get 70+ mpg? When it's running 16 miles on batteries? A Prius can't even get that mpg.

I'm wondering if Porsche figured out how to do it in a meaningfull way for the street with the battery system? The flywheel system is a no-brainer for the track. Ferrari hinted they would do something very different for the street. My guess is the batteries will charge when braking and will also be charged by the gas engine when coasting or idling. Then they're likely to be charged most of the time.

I wonder what will be happen when you go for a top-speed test in the 918 or new Enzo? I suspect the battery will run out before you hit Vmax.

 

The mpg and CO2 g/km numbers are based on what is in the real world the defunct euro test cycle/s. You can turn up at the test with the battery fully charged- it's meaningless. The street 918 is porsche laughing at the rule makers.

The street 918 doesn'y have KERS, it's hybrid. The track 918 RSR has KERS- the Williams system.

I'd imagine a street 918 driven normally, that is spirited, will turn in an mpg around 20.

 

The "facts" in this article are anything but facts. Its just someone speculating and making up things as they go along. I've heard some numbers from insiders and its not a 7.3 liter.

 

what numbers?

 

2011 P 4/5 C was about 30 seconds a lap slower than P 4/5 CM will be. It had too much downforce and not enough mechanical grip (Tires). We're 15 seconds faster today without KERS, developed engine, re engineered suspension, less frontal area nose, but with more mechanical grip (tires), less drag (Sharkfin), airscoop engine inlet and different wing and splitter.

No an Enzo would have to have hundreds of pounds less weight not to overheat it's
suspension at the Ring. Re engineered suspension is a massive job. (look at our re engineered suspension in the P 4/5 C thread).

As 250P said by gaming the rules. You can easily make and store 120 HP by charging a hybrid system with a petrol motor as the new Enzo and 918 will do but you can't do it by re capturing kinetic energy otherwise turned into heat by braking as we will do. Even on a long Ring lap with a LOT of braking we'll only be able to recapture about 60 HP for 50 seconds of use. IF they stuff enough storage capacity into the new Enzo I could see the extra boost lasting 2 minutes which is more than enough time to reach VMAX. At the Ring we reach VAX max MUCH quicker than that. Twenty seconds of KERS on the long straight will get us to a VMAX as much as 30 KPH faster than last year. Even today we're 12 KPH faster just with half of our new aero package.

Nothing is for free it will take more than 120 HP for the new Enzo to store 120HP and IMO street braking and idling won't be enough and you'll notice the drag when the system recharges.

 

As I see it, the questions for the new Enzo will be : how much energy, in joules, will the electrical system be capable of storing? And how fast will the combination of motor plus regenerative braking be able to recharge it?

The horsepower boost will depend on how fast that energy is released, or used, to augment the gas motor. Power (in watts, or HP) = energy/time. It may be that the electrical boost in the new Enzo is user-variable, in this sense : If you release/use that stored energy quickly, you get big HP boost ... but only for a short time. If you use that same stored energy slowly, you get small HP boost ... but for a longer time.

This should prove to be very interesting ...

 

It will...

 

Is the 29th press-release by Ferrari to cover the Enzo replacement?

 

I'm not sure but I hope so!

This is the F152, i.e. the 599 replacement, not the next Enzo. The car will be unveilled next Wednesday, the 29th of February, and is going to be amazing. Front-mid engine V12, RWD, 750 CV, 350 km/h top speed.

 

think of the liabilty if somebody gets shocked by the KERS system

 

Thanks Jim. It sounds like a few mods to the Enzo might get it close to P 4/5 C. (-:

BTW, the Enzo's philosophy was to have a compact shape without extruding wings, spoilers, fins, etc... thus the shape it is (i.e., form meets function).

I believe Ferrari intends to recharge the batteries seamlessly using regenerative braking and something they call "load-point moving". My understanding of the latter is that they plan to use a system that allows the V12 engine to operate in a more efficient region (i.e., higher in its powerband), but maintain a lower vehicle speed. The excessive energy would then be used to charge the batteries. I guess when you work out all the math under normal driving conditions, the overall effect is lower emissions and greater fuel economy.

BTW, Ferrari still calls it KERS because it's recovering kinetic energy while braking. They add "HY" to it to show it's more than that: HY-KERS because the electric motor is used not just for acceleration. Basically it's a Toyota Prius that uses the excess energy of the V12 to charge the batteries.

 

Think of the liability if someone gets shocked by a toaster.

Or burnt by a stove.

Or shocked by a Toyota Prius.

Or burnt in a fire caused by an internal combustion engine.

I hope not.

 

Fortunately these are from '10, and not based on newer information!

 

They're in the latest issue in an article on Fellisa. They may be wrong but I bet there's some truth in them.

 

You would most certainly know much more than I would, I just thought it was an older ps done on a koenigsegg, functional, but not really attractive.

You've proven that a car can still be both, and I think that has set the bar quite high.

 

I haven't seen the new Enzo so I'm just guessing here but somehow I don't think they'd use something in an article about Fellisa that was WAY off base.

I'm also sure they'll do everything possible to make it look different than P 4/5.

It will be interesting to see how it turns out.

Late one evening Andrea turned to me and said:

"Jim you have killed my business. Your car will be a hard one to follow."

 

doesn't the KERS system assist breaking, IE it is connected to the wheel shaft and uses the EM force that is applied when the charging is done. Also Porsche 918 has e-motor in its front wheels, thus directly charges the batteries during the braking process.

 

The P system is the way to go as most braking is from the front but we can't fit electric motors on the front wheels.

Our system is attached to the primary shaft of the gearbox and works as you say as rear brakes when generating electric energy.

 

Air flowing through the doors?

 

ehh.

Hopefully the successor to the Enzo will remain unique and different in it's styling compared to Ferrari's current lineup. I'd be disappointed to see styling ques similar to the FF or 458.

 

Our 2012 nose will have even more airflow through that area by narrowing and lowering the front fenders.
