概念車除了向世人展示車廠的願景和抱負之外，還可以用來嚇人。Piaggio在09年EICMA意大利車展中所展示的概念車USB，賣相便絕對"嚇人"！USB全名是Urban Sport Bike，若純以電能推動，以時速60公里巡行，可跑50公里路程。結合2T GDI  heat engine聯手推動，極速約有100km/h。如果Suzuki Gemma見到USB的話，第一個反應應該係：咦？見到親戚？

At EICMA 2009, Piaggio explores the idea of urban mobility of the future: the result is Piaggio USB, a prototype, an exercise of
style, a workshop of solid ideas.  Designed by the Style Centre of Pontedera, directed by Marco Lambri, Piaggio USB takes our references beyond the boundaries of existing categories, combining ecology, pleasure, safety and connectivity to give shape to an original and innovative, two-wheeled mobility proposal for the third millennium.

Piaggio has always stood for innovation on two wheels. This has been the case ever since Corradino D’Ascanio’s intuitive spirit
who, more than sixty years ago, created the scooter par excellence – the Vespa - a bestseller whose philosophy of construction and use has been reinterpreted by different models, such as Beverly, up to the most technological scooter - MP3 Hybrid - the first
scooter incorporating a parallel hybrid propulsion system, with three wheeled technology and Ride By Wire accelerator.

In line with this tradition, Piaggio has now developed Piaggio USB (Urban Sport Bike), a prototype that represents the synthesis
and, at the same time, the potential evolution of the idea of urban mobility on two wheels. It is designed to offer an innovative
solution where environmental protection, safety, fun driving and connectivity become the key to the cities of the future.

A hybrid of shapes, technologies, motor vehicle architecture: Piaggio USB breaks the mould and stands as a new species in the
metropolitan scenario of the future.  In a world where the range of vehicles is constantly changing, Piaggio USB draws inspiration from the scooter, motorcycle and car world. Its design, whose distinguishing feature is its pure and sinuous shape, draws from worlds that are not the ones that are conventionally referred to for two-wheeled scooters. Its enveloping shape turns the scooter driver into the protagonist and conceals what is superfluous. Man is once again the centre of attention and the vehicle becomes a modern instrument to move SMARTLY in all conditions.

The benefits of innovative ergonomics, scooter-typical protection and convenience are combined with motorcycle dynamism. Rationality and excitement merge into fluid and dynamic shapes. Piaggio USB is incredibly sinuous and its smooth surfaces make it a quick, dynamic scooter, ready to take over any road.

Easy and intuitive, light and compact, Piaggio USB is designed to offer the convenience of a scooter and the comfort of a compact
car, without giving up sporty and fun driving. Utmost comfort is guaranteed by its highly protective surfaces, ensuing from a smooth
and aerodynamic design, and by its ergonomic seat, an innovative position that is halfway between a scooter and a car.

The prototype can develop into three different configurations: single-seater, like a sporty vehicle, two-seater like a coupe, or
with top-box, for the highest load capacity.  Innovation and distinction, in line with Piaggio’s outstanding tradition, both in its design and technology.  The propulsion is guaranteed by a power-pack made up of an evolved 2T GDI heat engine, coupled with an innovative electric machine installed in the back wheel. The electric propulsion makes the most of the innovative quality of nanotechnologies, thus offering top performances and top reliability.

The series hybrid configuration, with plug-in option, has been devised to ensure an average speed of use of 60 Km/h, and an over 100 Km/h maximum speed. For the electric propulsion only, the 2.5 Kw/h lithium-polymer batteries installed in the vehicle guarantee a 50 Km endurance at a cruising speed of 60 Km/h.  In performance terms, the power pack stands out for its high torque values – around 200 Nm – that guarantee excellent acceleration and very low consumption – around 1.5 l every 100 Km.

By making the most of the plug-in option, the vehicle turns into a ZEV (Zero Emission Vehicle).  Its weight – less than 130 Kg – its high torque values and its low centre of gravity make Piaggio USB an easy and fun-to-drive, other than an eco-friendly vehicle.
