Audi still hasn’t released any images of its new electric A1 e-tron concept, but it has suggested alittle details of the car. Distinct a dual previous e-tron sports automobile concepts which were both pure battery electric models, this asingle is the range-extended EV. Like a Chevrolet Volt, a A1 e-tron uses the notasbig battery pac k which allows it to go up to 31 miles upon the single assign with no emissions.

Once the battery is depleted, an internal combustion engine kicks in to driv e the 15-kilowatt generator as well as keep the A1 starting. However, unlike a Volt or Fisker Kismet, a A1 is using the single-rotor Wankel engine to expostulate the generator. Whilst Wankels have been not renowned for their fuel efficiency (much the conflicting in fact), in this application it could work well thanks to its high power firmness.

A range with the Wankel using is bumped up by another 124 miles to a total of 155. With only the 15kW generator accessible to sustain the battery, it will be engaging to see how most performance is degraded in that mode. Audi claims a A1 e-tron achieves 123.8 miles per gallon (U.S.) upon a breeze EU standard for ER-EVs. We should have some-more sum tomorrow, so stay tuned.

AUDI AG: driveline plan for a future – electric mobility as an integrated concept

* Q5 hybrid to be unveiled in 2010, A8 hybrid can be systematic from late 2011
* World premiere for A1 e-tron study at Geneva Engine Show
* “e-tron” to be Audi’s brand name for electric mobility

Audi is working intensively to answer questions of destiny mobility. In late 2010/early 2011 the Q5 hybrid will reach the marketplace, the initial Audi with a multiple of gasoli ne engine as well as electric motor. In Geneva Audi is exhibiting a A8 hybrid for the initial time as the judgment automobile: Its CO2 emissions of 144 g/km (231.75 g/mile) are the best figure in the full-size difficulty. Another world premiere in Geneva is the A1 e-tron pattern study, that shows that Audi’s imagination in electric expostulate systems extends down into the compress car shred. At a finish of 2012 Audi will launch a e-tron electric car which was seen last year during the Frankfurt Engine Show (IAA). THE small series will be built, and will be the initial electric car to reach a market.

In a words of Rupert Stadler, Authority of a House of Government of AUDI AG: “In future our customers will be means to choose from an increasingly broad range of driveline technologies. To accompany our high-efficiency TDI and FSI engines, you shall suggest electric energy in the most appropriate probable forms for a far-reaching range of mobility needs. A hybrid driveline will be followed by all-electric vehicles.” The “e-tron” name will have an important partial to foolaround. “Just as “quattro” has become the equivalentterm for all-wheel expostulate, so “e-tron” is to be a Audi code name for electric mobility,” continues Stadler.

When building pick drivelines, Audi is pursuing a strategy of introducing any record where it is appropriate for specific indication lines as well as markets, in other words where it will suggest customers poignant benefits.

“We regard the full hybrid as you know it today essentially as the very specific record for reducing fuel expenditure. In due march plug-in variety will demonstrate their strong points when drivers expect to cover longer distances in the pure electric mode, in combination with a conventional engine,” says Michael Dick, Member of a House of Management for Technical Growth during AUDI AG.

According to Dick: “A strength of a electric automobile obviously lies in the civic mobility area, where a demand for emission-free internal travel will strongly increase.” In addition to variety and electric cars, Audi continues to develop the long-term competence in the growth of simple propulsion concepts using fuel cells as well as hydrogen as an appetite carrier.

Each year Audi invests around dual billion euros in development projects, with the concentration on one after another swell in inne r combustion engine design as well as compared areas. Electric mobility is the further priority: In this area a e-tron uncover automobile seen at the IAA was a dramatic vigilance. During the same time, the assorted activities have been being grouped together strategically. Audi has established the e-performance plan house to deal with elect ric mobility topics. Given the autumn of 2009 a group has been at work upon the research plan of a same name, with support from a Sovereign German Ministry for Preparation and Research. Members of a group, consisting of AUDI AG development staff and scientists from assorted universities, have been working upon a growth of a brandnew overall electric vehicle concept, togetherwith the body, battery as well as energy electronics.

Audi A1 e-tron
Audi will be expanding its “e-tron” model family step by step: a A1 e-tron design study that a company is exhibiting at the Geneva Engine Uncover is an innovative Mega City Car (MCV). Like a sports cars in a same family, it is electrically propelled as well as has the operation of some-more than 50 kilometers (31 miles) in city traffic. With a rise energy outlay of 75 kW (102 hp), the A1 e-tron is additionally fun to drive.

When a battery’s appetite supply is tired, it is recharged by an unusually compress “operation extender” consisting of the single-rotor Wankel engine and an electrical generator with the charge rating of up to 15 kW.

This device gives the A1 e-tron an one more operation of 200 kilometers (124 miles). According to the breeze standard for determining the fuel consumption of range-extender vehicles, the mean fue l expenditure is 1.9 liters per 100 kilometers (123.8 US mpg), homogeneous to CO2 emissions of only 45 g/km (72.42 g/mile).

Audi A8 hybrid
Audi is displaying the A8 hybrid as an engineering investigate during a Geneva Engine Show. The dual power units – the 2.0 TFSI engine as well as a electric engine – have a total outlay of 180 kW (245 hp) as well as the torque of 480 Nm (354.03 lb-ft). They give the automobile the same outstanding performance as the large-capacity conventional six-cylinder engine. This oneafteranother downsizing demonstrates the fuel-consumption advantages in multiple with the electric driveline: a normal fuel expenditure is usually 6.2 l/100 km (37.94 US mpg), homogeneous to CO2 emissions of 144 g/km (231.75 g/mile).

The Audi A8 hybrid uses the together hybrid configuration – a highly efficient element which avoids nonessential friction and energy losses. The absolute electric engine integrated in between a 155 kW (211 hp) four-cylinder petrol engine as well as a eight-speed tiptronic delivery can supply the serve 33 kW (45 hp) to the driveline, as good as the vigorous 211 Nm (155.63 lb-ft) of torque.

The A8 design investigate is a full hybrid, which is to say a gasoline engine or the electric motor can propel it either alone or together. In the pristine electric dri ve mode the car can strech 65 km/h (40.39 mph) and cover a distance of more than two kilometers (1.2 miles).
