McLaren P1: nouvelle Mclaren F1 (codenamed P12)

[Corsugone]

Synthèse des 15 trucs à retenir sur le modèle :

1. The 90kg carbonfibre tub — McLaren calls it the MonoCage — that forms the basis of the P1 differs from the 12C’s because it incorporates the car’s roof and snorkel air intake, plus space for the battery and electronic systems. At its stiffest point it measures 5000 gigapascals (more than twice the stiffness of steel), while the fibres are stronger than 6000 megapascals (more than five times the strength of the highest-grade titanium).



2. Two clamshells fit over the MonoCage, at the front and rear. They are single-piece carbonfibre mouldings, and light enough to pick up with a pinched thumb and forefinger.



3. The obsession with weight saving extends to the windscreen. At 3.2mm thick (including a plastic interlayer), it’s 1mm thinner and 3.5kg lighter than the 12C’s.



4. The interior’s carbonfibre has had its top resin layer removed. It gives a more natural look and saves 1.5kg.



5. Each seat weighs 10.5kg. They can be manually slid fore and aft, but the backs are set at 28deg as adjusters would have added weight. The seat height is custom set to suit the driver.



6. The turbocharged 3.8-litre V8 is considered to be 90 per cent new, despite being based on the same unit as in the 12C. Changes include the cranktrain, fuel system, cylinder heads, block design, transmission and turbo systems.



The turbo operates at around 980deg C, with temperatures at the exhaust exit of around 900deg C.



7. The electric boost system was originally going to be called KERS, as it is in Formula 1. But the system has been dubbed IPAS (for Instant Power Assist System) as its capabilities and operating parameters are so different. The electric motor weighs 26kg and is more than twice as powerful as a KERS system, producing 176bhp versus the KERS set-up’s 81bhp.



8. The IPAS system’s battery weighs 96kg and has six modules, each carrying 56 cells. Power can be transferred between cells, to ensure the maximum battery power is always available. The P1 can run on electric power alone at up to 99mph and 
has a 6.5-mile range based on the combined European driving cycle. The battery is lifed for 10 years, based on the expected usage of the car, provided it is maintained properly.



9. The electric motor is used to sharpen throttle response and increase peak power. In addition, at the press of a steering wheel-mounted button marked ‘Boost’, it can deliver its 176bhp for up to 20 minutes, depending on the battery’s charge and the operating temperatures.

10. The battery charges using surplus power from the engine, or it can be plugged in and charged in two hours on a standard charge or 10 minutes on a fast charge. The V8 engine can also be used as a generator in preparation for electric use. McLaren took the decision not to recoup power from the brakes, as it felt the loss of brake feel far outweighed the benefits.



11. The P1 has been engineered to ride as well in town as it does on the race track. Key to this is its suspension, which is based on the 12C’s system but with added hydraulic control of heave (vertical body movement) that allows for independent control of ride height and vertical stiffness. In Race mode, the car automatically drops by 50mm and spring rates increase by up to 300 per cent. The P1 can corner at 2g, even on road-legal tyres.



12. With the rear wing extended to its maximum 300mm and angled to its maximum 29deg, and the front wings adjusted to their most extreme setting, the P1 develops 600kg of downforce. This is achieved at 160mph, after which the front and rear wings adjust to shed any additional downforce. If they didn’t do this, the amount of downforce generated by the P1 (around 1000kg at 217mph) would require its suspension to be reinforced.



13. A Drag Reduction System (DRS) mimics that used in Formula 1. It is operated by a button on the steering wheel and within half a second can flatten the wing angle and reduce drag by 23 per cent. It deactivates if the button is released or if the driver brakes heavily or steers significantly.



14. Another F1-derived performance enhancement is McLaren’s Brake Steer system. Pioneered in the sport in 1997, and subsequently banned, it uses the ESC system’s hardware to brake an inside rear wheel if the P1 enters a corner too fast, in order to tuck the nose in.

15. The carbon-ceramic brakes are infused with a surface layer rich in silicon carbide — one of the hardest substances known. It delivers immense stopping power close to 2g, good pedal feel and greater heat dissipation and durability. The materials were first seen on the Ariane space rocket.

Bon, EVO ils n'ont pas été très tendres dans les compte-rendus de leur long term, en fait ils ont fait comme nous, ils louent les mérites de la voiture qui est probablement mieux aboutie que la 4C et ils dénigrent le fait qu'elle ait des lacunes graves dans le design des accessoires. Ce que je retiens c'est que pour l'achat d'une P1 comme pour celui d'une voiture normale, quand il s'agit de poser son autographe au bas de la commande les vrais arguments sont plus émotionnels que rationnels et que les aspects de brand identity notamment jouent un grand rôle. Pour reprendre l'exemple de la 4C, on peut voir sur le thread dédié que les personnes ayant passé commande sont surtout fans de Alfa et de l'image que cette voiture promet, plus que de dire, je compare la 4C avec l'Elise et je prends celle qui rempli le mieux mes critères.

Florilèges de couleurs ... Ma préférée, la première qui doit être Orange Blood (Orange Sanguine), les autres sont aussi superbes, un bémol sur la noire ...

Les photos de la première McLaren P1 "suisse"... c'était juste avant la livraison au client, sa première sortie pour faire le plein, vendredi dernier chez McLaren Geneva !





Puis, le lendemain, à Bresse, la chance de la revoir à nouveau...





Tellement plus belle en situation réelle !!

La P1 set sold out ça y est !!
C'était pas gagné d'avance, félicitations !!

Ils sont pas tendre avec Porsche...

Back in May McLaren's sales and marketing director Greg Levine told us in confident mood that "Porsche doesn't have a chance of selling 918 units" of its contender in the three-way electric-assisted power war and that "if the P1 was in a class of one we'd still only build 375 because you need the exclusivity."

[Corsugone]

Il serait tentant d'écrire que Mclaren a réussi un coup de maître mais non, ils ont simplement écouté les prospects sérieux demandant pas plus de 350 voitures (dixit Ron Dennis), l'usine en produira 375, on n'est pas loin. Les prospects (Anglais) avaient bien précisé qu'ils ne passeraient pas commande d'un modèle de plus dans la gamme ou produit au-dela d'un seuil ne garantissant pas sa côte.

Ferrari applique la même politique à une différence, ils n'ont encore rien annoncé et parions qu'il reste encore une poignée de voitures à vendre. Au final, cela se conclura comme Mclaren, sold out. Concernant Porsche, à la vue du prix et du nombre de 918 produites, cela devient une quasi-série, bizarre comme démarche. Exception faite de la F40 qui fut produite bien au-delà du quota annoncé, pas souvenir qu'il exista un jour une demande aussi importante pour une hypercar. Au départ Ferrari annonça une production très inférieure au 1043 sorties de l'usine si je ne me trompe pas sur le nombre.

Au final, le grand gagnant sera surement le client Mclaren, moins chère que la Ferrari et la plus exclusive des trois. Et que dire de l'expérience client ...

Le plus intéressant dans cette affaire reste qu'il aura fallu attendre plusieurs mois avant que l'un des protagonistes annonce officiellement "sold out". Il fut un temps où tout serait parti en un claquement de doigts. Les temps changent ...

Dernier point, contrairement à LaFerrari, on ne trouve pas (déjà) de P1 sur le boncoin ou lacentrale

De l'intérêt de la valeur d'une Mclaren F1 ...

All examples of the P1 destined for the Americas, Asia Pacific and the Middle East had already been sold earlier this year. The continued economic uncertainty in Europe has been put down as the reason why the P1 took longer to sell in Europe.

McLaren received a sales push for the P1 in North America on the back of its appearance at the Pebble Beach after a McLaren F1 sold for $8.47 million at an auction, raising interest in the firm. Confirmation that the P1 had lapped the Nurburgring in under seven minutes earlier this month is believed to have prompted another raft of sales.

Potential customers are now being asked to register their interest with McLaren, lest any of the existing buyers change their plans during the build process. To date, 12 McLaren P1s have been completed.

Around 75 per cent of P1 customers have opted for some level of unique design from McLaren Special Operations, pushing the average sale price of a P1 above £1 million.

ça roule aussi en escadrille ...

Suis-je le seul à trouver dommage de choisir le noir pour une super-car?

[Greezer]

Je suis de ton avis aussi, même si je lui trouve un côté vraiment sympa en noir. Ma préférence irait vers une jaune mclaren, certainement...

[Corsugone]

Une couleur sombre ne semble pas la chose la plus proprice sur cette P1.

[sylvain007]

L'aileron est pas censé sortir qu'au besoin?

Ils trouvent la ligne si ratée que ca pour le laisser "ON"?

[Greezer]

A mon avis cela dépend partiellement du mode utilisé. Je ne serais pas surpris qu'il soit d'office déployé en "Track" pour maximiser l'appui.
