novità Lamborghini: Urus e Jota?

[gentle-man]

da autoblog:

Lamborghini si prepara a presentare l?erede della Murcielago, la Jota, ma avrebbe anche allo studio un nuovo modello, chiamato Urus (nome già ipotizzato a suo tempo per la Estoque), da contrapporre all?erede della Ferrari Enzo. I progetti Lamborghini non sarebbero direttamente collegati, infatti la Urus potrebbe utilizzare una versione rivista e corretta del futuro telaio in carbonio della Jota. La carrozzeria dovrebbe essere totalmente in fibra di carbonio e corredata da appendici aerodinamiche attive. Le due supercar dovrebbero utilizzare lo stesso e rinnovato V12 6 litri, con step di potenza diversi: circa 700Cv per la Jota e circa 800 Cv per la Urus: se così fosse la Urus potrebbe persino raggiungere i 100 km/h in meno di 3 secondi.

Il debutto della Jota è atteso nel corso del 2010, mentre la Urus potrebbe fare il suo debutto nel 2011 ed essere nei garage dei più facoltosi collezionisti del globo nel 2012. Guarda caso, proprio in quell?anno debutterà anche l?erede della Enzo, che secondo le ultime dichiarazioni di Amedeo Felisa monterà ancora un motore aspirato zeppo di tecnologia, e non un biturbo come ipotizzato quando iniziarono a circolare le prime anticipazioni della FX70.

non sbagli

As if the Miura wasn't already radical enough, Lamborghini let test driver Bob Wallace make an experimental version that was even better. Prepared as a quasi-racecar, it had no compromises to comfort. Known internally as 'Miura Privata' by the factory, the project was later named Jota to potential customers.

Wallace described the car as a testbed "to see what could be done to improve engine oiling, stabilize handling and provide overall better build quality." Although eligible for Appendix J racing, Ferruccio's strict no-racing policy meant the Jota remained as one of the huge 'what ifs?' in automotive racing history.

Only one original Miura Jota was ever made, and it was Bob Wallace's personal test car built around chassis #5084. He used it to test various ideas that would prepare the Miura for the track and improve overall performance. Having plenty of time on his hands, the Jota became evermore radical to the point were it eclipsed standard Miura performance by several degrees.

The main focus of Bob's modifications was to decrease and balance weight. This meant the car had a completely stripped interior, single window wiper, Plexiglas windows and fixed headlights. Most of weight savings came from the use of a light-gauge aluminum alloy called Avional which was used for the new body, floor pan and front spoiler.

A proper weight balance was achieved by repositioning the fuel tanks into the sills and the spare tire just behind the engine. This reduction in weight, combined with the a near perfect front to rear balance, must have made the Jota handle on par with other race cars of the period.

From the outside, the new Jota was instantly recognizable from its Plexiglas headlight and aggressive front splitter used to decrease front lift. At the side were new air apertures to increase brake cooling with riveted-in ducts.

Under the hood, the V12 received a comprehensive race treatment that used aggressive cams, an increased compression ratio of 11.5, unfiltered Weber carburetors, and a straight-through 'Megaphono' exhaust. Depending on the state of tune, 370 to 440 bhp was reached which was more than enough for the 1764 lbs (800 kgs) it propelled.

To keep everything in check, the transmission and engine cooling systems were separated and a dry sump lubrication system was installed. Power was transferred to the rear wheels trough a close-ratio ZF differential.

Soon after Wallace's modifications proved the Miura could become even more serious, customers began to request Jota-like options in their orders. Lamborghini obliged and six cars, sometimes called Miura SVJs, cosmetically mimicked the performance of Bob's original.

Unlike the original, these customer cars had some interior comforts, but kept the purposeful body modifications and engine tuning. They also had suspension, exhaust and brake cooling upgrades. One or two received dry sump lubrication and an auto blocking differential.

While the customer cars didn't match the raw performance of Wallace's original, they did offer a huge improvement on an already outstanding supercar. No doubt they are now the most sought after Lamborghinis in existence.
