Well-informed sources have recently mentioned the preference of a Maserati-derived 4.3 litre V8 engine by Alfa Romeo for their 159, Sportwagon, Brera and Spider GTA models. This engine - which is an evolution of the 4.244 cc GranSport unit - will be fitted with Uniair (which was recently showcased in the CRF Sportiva Latina at the Barcelona Motor Show) and will allegedly pump out 440 bhp at 7000 rpm with 505 Nm of torque. The engine has similar dimensions to Alfa’s V6 and only weighs 183 kg. With minimal modifications, open to after market tuning specialists, the Maserati V8 has the potential to deliver well over 500 bhp. An out-bored, in-house high output variant, for use in possible future Alfa Romeo Supercars and the 169 GTA, is also under development, and will yield approximately 500 bhp.

A benefit of this V8 engine over the initial plan to use a twin turbo version of the 3.2 JTS V6 is the reduced torque (505 Nm compared to the Biturbo 3.2 V6’s asphalt-ripping 680 Nm), enabling the possibility to not only have a 6-speed automatic transmission but also manual and Selespeed options as well. Another problem with the serial Twin Turbo 3.2 litre V6 engine, which has been actively tested under an Alfa Romeo 166 prototype, lies in the power-band, with maximum power being achieved at only 6000 rpm.

True to the Gran Turismo Allegerita tag, these high performance Alfa’s will be lightweight: the 159 GTA will have a 130 kg weight reduction. The V8-engined GTA’s will retain AWD, as the V8 engine is to be mounted transversely similar to the old Lancia Thema 8.32. Part of the weight saving objective could be achieved through using high-performance parts such as Brembo CCM (Composite Ceramic Material) brakes. These alone weigh 30% less than alternative cast iron discs, and are currently used on high performance cars such as the Ferrari F430.

Offering top end performance is a prerequisite in future Alfa Romeo’s, strongly understood by Alfa Romeo engineer Paulo Massai, who believes that future cars should offer more power than their competitors. Centro Ricerche Fiat also play a crucial role in this respect, having developed the Uniair system, as well as a high performance adaptive rear differential which will feature on the more powerful models. Another recent design, which may be used on future GTA cars, is a retractable front spoiler mounted aerodynamic barrier, offering additional braking in a method similar to that of the Mercedes-McLaren SLR. Clearly, future GTA models will surpass the 250 km/h limit imposed on their German counterparts, requiring all the stopping power available.

cari ragazzi l'articolo di italiaspeed dice tutte cose vere, ho parlato lunedì con un tizio che ha visto qualcosa + di un progetto/product plan e mi ha anticipato esattamente le stesse cose.

Sogniamo finchè non le vediamo nei saloni... stanno x arrivare, tutto sta alle capacità finanziarie del gruppo da gennaio in poi. Se 159 mantiene le aspettative siamo a cavallo.

Granturismo, il V6TT selespeed non si può: ss è un cambio meccanico elettroattuato e la coppia sarebbe effettivamente troppa da sopportare. Hanno testato proprio come dice l'articolo 3 166 muli, con TI e V6TT con i vari cambi: i meccanici si stracciavano, mentre l'automatico cmq non rendeva benissimo.

Mica potevano andare a prendere un cambio auto da GM mutuandolo dai grossi pickup, p oeggio da una el camino con 700cv... :mrgreen:

trasversale..................scusate ma sono e rimango scettico

per ora non si poteva fare altrimenti, troppo costoso riposizionare tutto... 169 sarà longitud.

Accontentiamoci, anche perchè è un accontentarsi di lusso e da quanto ho capito sarà una spanna sopra alle concorrenti a livello prestazionale (RS4 e M3, la C AMG non la considero manco).

Pare che siano riusciti ad avere una ripartizione ottimale nonostante tutto...

D'altrone, so che mi mocolerai ;) , se porsche da 50 anni è un mito con i sacchi di sabbia nel muso....

purtroppo il mito c'è... tanto quanto i sacchi di sabbia :redd:
