Sophisticated hybrid systems that utilize an internal combustion engine to power one axle and an electric motor spinning the opposing one seems to be all the rage these days and could potentially form the next wave of green car technology to sweep the auto industry.

By powering two axles instead of one, the innovative drive systems, also known as a ‘through-the-road’ hybrid, offer all-wheel drive capability without the associated heavy weight of multiple driveshafts and gearsets typical of most all-wheel drive vehicles.

Not surprisingly, several major automakers are flocking to the technology, the leader being France’s PSA Peugeot Citroen, which will be launching the world’s first diesel-electric hybrid complete with a through-the-road system in the form of the new Peugeot 3008 HYbrid4.

Audi, too, is investigating the technology, previewing an A5 prototype fitted with a similar setup. Falling under its e-tron division for development of electrified cars, the new A5 e-tron quattro is only a prototype but it shows the expanded direction Audi is taking for its next-generation of cars.

Under the shell of the regular-looking A5 is a 211 horsepower and 258 pound-feet of torque 2.0-liter TFSI turbocharged gasoline engine, which is matched to a compact electric motor with 45 horsepower on tap.

Both of these powerplants are used to drive the front axle via a dry clutch and lightweight four-speed automatic transmission.

In the rear is a second electric motor, this one with 81 horsepower and 221 pound-feet, which drives the rear axle. Note that this motor is only used when additional acceleration is required or if sensors at the wheels detect a loss of traction.

Both electric motors, however, can also be used to recover brake energy when the driver hits the brakes in order to top up the car’s lithium-ion battery pack.

The story doesn’t end there. The prototype can also be plugged into a regular household power outlet to charge up the batteries. Once fully charged, an electric only driving range of 40 miles is possible at speeds of up to 62 mph. If increased range or performance is needed, the driver need only keep his or her foot on the pedal and the internal combustion engine will kick in.

Of course, all of this extra technology adds weight so engineers have used more lightweight aluminum and carbon fiber to shed some pounds. Thanks to their efforts the prototype tips the scales at around 3,500 pounds, which is about the same as the all-wheel drive A5 fitted with just the 2.0-liter TFSI engine.

As mentioned, this is only a prototype and any production release would still be years away--at the earliest.

é un veicolo-laboratorio.

come dicevo prima, a me richiama un po' troppo questo logo:

hk047-wiesmann-logo-40x50.jpg

Su un numero arcaico di AlVolano comparve una prova "auto da sogno" di una Wiesmann gt4, e in quell'occasione riportarono che il geco era stato scelto dalla Wiesmann quale simbolo di tenuta di strada eccellente etc etc.

Ora sarà il simbolo della tenuta di strada premium :)

Il logo del geco è associato da una vita alla sigla "Quattro" di Audi.

Mi sembra addirittura che lo fosse sin dagli anni 80.

ma nelle auto ibride è obbligatorio lo scempio della strumentazione?

Confermo e sottoscrivo.

Può apparir nuovo ai più perchè non vien usato praticamente mai.

cavolo, è un marchio storico. Pure azzeccato perchè si arrampica fin sopra i muri. E' diventato un po' zarro anni dopo mica per colpa sua, ma delle migliaia di tatuaggi che si vedono in giro..

Beccatevi questa:

che figuraccia ho fatto :/ scusate :(((.. sinceramente però tra le ultime "quattro" non l'ho mai visto applicato..

@Cosimo l'audi da te postata è più vecchia di me di ben 10 anni :§:mrgreen::mrgreen::mrgreen:
