Audi A1 e-Tron Concept
As expected, Audi revealed today its brand new A1 e-Tron Concept at the Geneva Motor Show. The new concept represents the third vehicle from the e-Tron family, the first was unveiled back in 2009 at the Frankfurt Motor Show while the second made its debut in January at the Detroit Auto Show. This third concept represents another approach from Audi and it was designed as a four-passenger, two-door MCV city car specifically for use in the metropolitan areas of Europe and North America and in the rapidly growing megacities of Asia and South America. The new car uses a synchronous electric motor delivering a peak power of 102 hp or 75 kW (continuous output is rated at 45 kW or61 hp) but also 150 Nm (110.63 lb-ft) of torque continuously available and peak torque of 240 Nm (177.01 lb-ft). The whole amount of energy us transmitted to the fron wheels via a single-speed transmission. A fully depleted battery can be recharged in approximately three hours from the 380 volt grid. The large electric motor powering the A1 e-tron can convert braking energy into electric current and feed it back into the electrical system. The energy can be stored in the storage unit arranged below the floor, ideal for the center of gravity and weight distribution.
The battery pack is shaped like a T, with the short transverse beam filling the rear section of the center tunnel and the cross-beam filling that area in front of the rear axle where the fuel tank is otherwise located. The 380 volt lithium-ion rechargeable battery has a nominal energy content of 12 kilowatt hours. It comprises 96 prismatic cells and weighs less than 150 kilograms (330.69 lb). The Audi e-Tron has a range of 50 kilometers (31.07 miles), while on longer trips the battery is recharged by a particularly compact internal combustion engine mounted below the luggage compartment. The range extender is in fact a Wankel engine, but other compact concepts are also possible. The small single-rotor Wankel has a chamber volume of 254 cc and runs at a constant 5,000 rpm in its peak efficiency window.
The driver can also turn the range extender on and off as necessary with the push of a button. The fuel tank holds 12 liters (3.17 US gallons). The extra range, which is intended primarily for interurban driving, is 200 kilometers (124.27 miles). Regarding its performances, the car, which weighs only 1,190 kilograms (2,623.50 lb), can sprint from 0 to 100 km/h (62.14 mph) in 10.2 seconds and has a top speed of more than 130 km/h (80.78 mph). According to the manufacturer, the car has a fuel consumption of just 1.9 l/100 km (123.80 US mpg), which corresponds to CO2 emissions of 45 g/km (72.42 g/mile) Regarding the design, the car that you see in the photos has a special Aqua Mint, pearl effect paint finish and a contrasting roof arch finished in High Gloss Steel dark The looks are completed by the 18-inch wheels with a 20-spoke turbine design.
