AUDI METROPROJECT QUATTRO
Audi paid homage to Japan's flair for miniaturization with its sub-compact metroproject quattro design study, which made its debut at the Tokyo Motor Show.
Condensing the premium quality, innovation and design for which Audi is renowned into less than 4 metres of road space, the metroproject could provide clues to the future Audi A1 sub-compact production car.
Power is provided by a modified version of the 1.4-litre Turbo FSI petrol engine recently adopted by the A3 in Europe, combined with a lithium-ion battery-powered electric motor mounted behind the rear seats, reducing fuel consumption and emissions by around 15%.The petrol engine's increased 150hp (up from 125PS in the A3) is delivered at 5500rpm. The electric motor adds 41hp and considerably more torque, so that when both in unison, the metroproject is able to accelerate 0-62mph in 7.8sec.
Delivered via the S tronic dual-clutch transmission, the impressive performance can, in the right conditions, culminate in a top speed of 124mph. With slightly more judicious accelerator control, a combined economy figure of 57.6mpg is possible.
If the driver opts for electric operation alone - an advantage for urban driving and shorter distances - the metroproject is able to cover up to 62 miles at speeds of up to 62mph, silently and cleanly, before its lithium-ion batteries need to be recharged. Energy released during braking is transformed back into electrical energy, helping to conserve resources more effectively.
When only the petrol engine is running, the metroproject sends drive through its front wheels, and while powered by the electric motor on the back axle alone, it is effectively rear-wheel-drive. When the two operate simultaneously, the Audi is able to offer four-wheel-drive.More enthusiastic driving, which would call the two power sources into play simultaneously, is enhanced by a sophisticated McPherson strut front and four-link rear suspension configuration, electromechanical speed-sensitive power steering with a low energy draw and Audi magnetic ride adaptive damping technology which has won plenty of praise already in the TT and R8 sports cars.The Audi drive select system introduced recently in the all new A4 Saloon, which enables the driver to fine-tune suspension, steering and transmission characteristics to suit their preferences, also helps to bring the best driving experience.
The highlight of the cabin is the new, removable hand-held Audi mobile device, which not only offers mobile telephony, GPS navigation plus audio and video playback, but also serves as the control unit for numerous vehicle systems which can be set and adjusted from outside the car. The driver can, for example, enter destinations into the satellite navigation, program the audio system or switch on the heating from the comfort of his armchair at home before setting off. The handheld, touchscreen system can even decipher handwriting and communicates with the car by way of a WLAN connection.
