Well, if Mulsanne Mike agrees with me ... he must be right!

R15+, really? That "lets throw a can of red paint over the car in a wind tunnel and see where it sticks" livery was hideous.

I'm hoping for Mobil 1 colors...

I'm hoping for red, it won't happen but it'd be a nice 'tribute' to the 917.

But if they want to use batteries then they'll need to keep the weight down in all other areas of the car including the engine. So no V8. If they are using Zytek Engineerings electric motors then there will be additional weight savings there. Of course those motors are very expensive. But they are featherlite in every sense of the word. |

From looking at the A123 website, the battery packs can be sculpted to fit the space. They will probably provide a very centralized and low center of gravity in a compact package that can be constructed to distribute weight as needed. That was my first impression after seeing some of the products of A123.

If you wanna go the 4 MJ way, than you need about 40kg of batterypack to reach 0,7 MJ of energy to store. |

You are looking at this wrongly. Energy density is not an issue for lithium ion battery, power density is! The hybrid system needs to be charged in a very short period of time.
http://ev.sae.org/article/10599 gives the following numbers for the A123 battery pack in the electric Drayson Lola. Quote:
Again using the Drayson battery pack as example. Quote:
Power density is the main reason why Toyota went for supercapacitors. The electric motor in the TS030 is 300 hp = 221 kW. A lithium ion battery would have to weigh more than 100 kg. |

Just one exhaust hole... it means the car will probably be fitted with a 4-in line turbocharged engine, and displacement will be 1.8-2.2 litres. Smaller engine means lower weight and more space in the chassis to place hybrid system. This choice is to reduce the weight of the car, to fit the battery package as a ballast, placing it in the best way to lower the centre of gravity of the car as much as possible.
I think this choice can be the right one, to have a very well balanced car saving weight as much as possible. Petrol engine is lighter than diesel one, so Porsche could be further advantaged with a 4-in line in confront of Audi and maybe Toyota (assuming they will preserve their 3.4 V6 engine). |
