Hybrid Ferrari: 09 Ferrari F60 with KERS system (yes, it's a hybrid!!!)
« on: January 12, 2009, 06:42:47 PM »

Technical analysis of the Ferrari F60 , now "only" revs up to 18000RPM per regulations...with the KERS hybrid system (kynetic energy recovery system).  Just like a Prius does, sort of... Grin

At a low-key event at Mugello today, Ferrari launched their 2009 car, called simply the F60. Despite being built to the dramatically different 2009 rules, the car appears to retain the DNA of its predecessor.

Ferarri F60 detailNow equipped with a KERS system, slicks and bodywork to meet the new rules, the car is the first chance we have seen to see a definitive 2009 car. Slightly shorter than the F2008, the F60 cleverly exploits every blind spot in the bodywork rules to recoup the 50% loss in downforce from its smaller wings and diffuser.

(...)

The sidepod fronts are the main area of aerodynamic freedom, as they are described in the rules as the area for side impact protection and thus excluded from the limitations placed on the three volumes making up the rearward part of the sidepod. To exploit this, Ferrari have shortened the sidepod front as much as possible to allow more vanes to be added.

As this area still needs to contain the side impact protection, a curious extension to the upper front of the sidepod has been added. Nick Tombaziz said this was for aerodynamic reasons rather than for a side impact structure.

(...)

Mechanically the car sports a new Brembo braking system and new geometry for the front suspension to maximise use of the slick tyres. The engine, coded as the 056, has been re-tuned to 18,000rpm limit and to last three race weekends as per the new rules.

The engine has been submitted to the FIA for homologation and the changes largely have involved inlet and exhaust tuning, as well as oil and fuel development. Still allied to a carbon titanium gearbox, the power train now includes the KERS system, which appears to drive its motor\generator off the front of the engine.

Wow, this sounds eerie!  Somebody just posted this, who was there at the track today:

"Ferrari was testing something very strange (IMO). Gene was driving the car, and at the straight, the engine just stopped, no sound from the engine, running by inertia, but then at the end of the straight, I don't know how, but he could start again the engine and complete the lap, they did it 3-4 times."

Running by inertia or running from batteries?  Or something else?  I believe that with the KERS, and you tap on the brakes, the engine simply stops running to save fuel (essential in a racecar, this way you can make a pit stop later etc, or even win a fuel strategy race).

Maybe they can just run the car like this for many laps for fuel efficency, and then later use the stored energy for extra power when overtaking when needed?  Hummm...

Boy, this year's F1 looks exciting!

Where do they keep the batteries?  In the driver's lap?

The Bosch system, used by other teams, don't use batteries, it uses a flywheel "battery", spinning in a vacuum at 140.000 to 160.000 rpm :   Cool

Quote
The system is not only suitable for Formula 1 where the German firm is speaking to “a lot of teams, not quite all but a lot” but it can also be applied in the WRC or Sportscar racing.

(...)

we are trying to keep individual rotational masses down, and to counteract the gyroscopic effect we mate pairs of flywheels, you can expand the storage system endlessly in multiples of 2” reveals Wildner. “The flywheels are basically a simple electric motor, which run at between 140,000 and 160,000rpm.  You spin them up using the drive motor as a generator, and store up the electric energy as rotational energy the to boost is the opposite process and the energy is released as electricity to the motor generator
(Racecarengineering.com)

Ferrari will use some chemical batteries with some super light and exotic materials, that need to be water cooled.  I think they're located around the driver cockpit:

Magneti Marelli has revealed it is to join Flybrid, Williams, Zytek and Bosch in offering an off the shelf solution for Formula 1. Its KERS is capable of a maximum energy storage of 400Kj per lap with a maximum 60Kw power boost as per the regulations. The system itself is fairly conventional, using a single liquid cooled brushless direct current motor generator unit (MGU), which operates at around 120 degrees C. Also included in the system is an in house designed KERS Control Unit (KCU) with a similar temperature capability. The battery pack is an ousourced part due to the complex chemistry involved in its development.
It was developed with a team (many suspect Ferrari) and is fully integrated with that operations powertain and is not an optional extra like some other systems.]Magneti Marelli has revealed it is to join Flybrid, Williams, Zytek and Bosch in offering an off the shelf solution for Formula 1.
