Boot-mounted rotary range-extender for Audi s A1 e-tron prototype

21 2012

AUDI is pressing with research and development of technologies, part of which is a iteration of its petrol-electric A1 e-tron as part of a German government-funded for electric mobility program will start early year.

Rather than the prototype s 15kW rear-mounted rotary range-extender engine, the A1 now has a three-cylinder 1.5-litre petrol and two electric motors to boost power output by 73 per cent to

Fuel consumption has been halved, to about 1.0 litre per 100 0.2L/100km lower than a Volt and top speed has been beyond 130km/h.

More a second has also been off the A1 e-tron s 0-100km/h acceleration which is now claimed to be less nine seconds.

Audi the new A1 e-tron a dual-mode hybrid its 17.4kWh battery pack a range of up to 90km at speeds of up to with the petrol engine in to generate power or drive the for longer journeys or higher started and assisted by a second motor that also as a generator to charge the battery

A single-speed transmission and claw enable the engine and motor to be or disengaged from the driveline on the operating mode.

The original A1 s range-extender engine was not directly to the driven wheels and the car could hit but had a shorter 50km electric-only from the smaller 12kWh

At speeds of 130km/h or more the new A1 s petrol engine provides of the propulsion but the electric motor can be at any time to improve fuel-efficiency or performance.

The motor used for electric-only produces 85kW of power and of torque, while the petrol produces 95kW and 200Nm of and its attached electric motor is at 50kW and 210Nm.

Providing the pack under the rear has enough charge, drivers can an electric-only running mode for driving, with efficiency or petrol-electric running modes can available.

Audi says the A1 s driving feel is similar to of a battery electric vehicle as the does cannot detect changes or the switch between or petrol-electric running.

A fleet of first-generation A1 e-trons covered more than as part of a trial in Munich will conclude at the end of this

The first stage of the trial the participants being lent a 1.4-litre petrol A1 to provide a comparison before being an e-tron to use just as they have the conventional car.

participants got used to maximising its range and travelling more the average distances travelled on alone rose from 76 per to 91 per cent.

Initial participants charged A1 e-trons at public charging and at their workplace, while the round had a wall charger at their home for overnight

Other Audi technologies this week include a iHEV idle-stop system also deactivates the engine freewheeling.

The system works when used with new technology Audi calls efficiency assistant (PEA), helps the driver save by helping them plan for the ahead and reduce reactive and braking inputs.

Audi has committed to offering at least one variant under the e-tron in each vehicle segment by
