Futuro A5......más ligero motor 2.5 TFSI 408 CV's.

[NeverMinds]

Parece que el futuro del A5 pasa por el menor peso en combinación con motores TFSI de cinco cilindros (TT-RS-RS3).

 

 

Driving experience with the technology of the Audi quattro concept showcar.

 

"An especially attractive technology platform can be experienced in the form of an Audi A5. The lightweight 2.5 TFSI 5-cylinder turbocharged engine with 300 kW (408 hp), familiar from the quattro concept showcar, accelerates the test vehicle. The body of the is hand-built from aluminum components according to the ASF principle. Add-on parts such as the hood and the rear hatch are made of a carbon fiber composite material. Lightweight sport seats are installed up front. This one-off model weighs just 1,400 kilograms (3,086.47 lb). Its power-to-weight ratio is 3.4 kilograms (8.16 lb) per hp, better than even that of the Audi RS 5, whose 4.2-liter V8 produces 331 kW (450 hp). The technology platform’s performance is awesome, when accelerating, when braking and especially when cornering.

 

The Audi quattro concept, of which a 1:4 scale model will be on display at Tech Day, is the ideal successor to the Audi Sport quattro from 1984. This is true for the compact length of 4.28 meters (14.04 ft), for the powerplant – a five-cylinder turbo with 300 kW (408 hp) – and for the low weight of around 1,300 kilograms (2,866.01 lb). Each hp only has to move 3.2 kilograms (7.05 lb) of weight, leading to exhilarating performance. The quattro concept catapults from 0 to 100 km/h (62.14 mph) in just 3.9 seconds.

 

Unlike the 1980s classic, the Audi quattro concept has a body of aluminum. This is assembled in typical ASF fashion from extruded sections, pressure diecast components and aluminum panels. The bodyshell weighs only 159 kilograms (350.53 lb), around 40 percent less than a comparable body made of steel sheet. The hood, the rear hatch and the moveable spoiler are made of a carbon fiber-reinforced composite."

Es el futuro... gasolina turbo, menos consumo, mejores prestaciones, será un avión ese motor.

Me gusta ese motor en sus actuales variantes de 300, 343 y futura version de 408 CV, aunque me gustará más todavía cuando saquen los motores diesel biutbor de 2 litros de 204CV e igual también con 220CV, y por supuesto las versiones del 3 litros nuevo de los A6, A7 y A8 con los 245CV actuales o los rumoreados 265CV que debe llevar en breve ese motor en el restyling del A5...

Se perderá el mágico sonido de un V8 :o

Pero las prestaciones hablan por si solas
