H Audi έδωσε μερικές φωτογραφίες από το πως αναπτύσσει το R8 e-tron μέσα στο εργαστήριο της. Η έκδοση παραγωγής του, που θα βγει στην αγορά από τα τέλη του 2012, θα κατασκευάζεται στο εργοστάσιο του Neckarsulm. Μια μικρή ομάδα εργάζεται πάνω στην τρόπο κατασκευής του στο ίδιο εργοστάσιο και η Audi μας δείχνει το πως. Το σασί του θα είναι από αλουμίνιο και χάρη στην τεχνολογία Audi Space Frame technology (ASF) θα ζυγίζει μόλις 200 κιλά. Συνολικά, το R8 E-tron θα ζυγίζει ακριβώς 1.600 κιλά. Είναι γνωστό εξάλλου ότι η Audi την πενταετία 2011-2015 θα επενδύσει στα εργοστάσια του Ingolstadt και του Neckarsulm περισσότερα από 5 δις ευρώ με τα περισσότερα από αυτά τα χρήματα να πηγαίνουν για την ανάπτυξη νέων προϊόντων καθώς και στις μελλοντικές τεχνολογίες ηλεκτρικών και υβριδικών συστημάτων,

Αποδίδοντας 313 άλογα και 457 κιλά ροπή οι 4 ηλεκτροκινητήρες του R8 e-tron, θα του επιτρέπουν να κάνει τα 0-100 χλμ/ώρα σε 4.8 δευτερόλεπτα. Οι άνθρωποι της Audi έχουν σκεφτεί τα πάντα και έτσι τοποθέτησαν τις υδρόψυκτες μπαταρίες λιθίου βάρους 550 κιλών πίσω από τα καθίσματα ώστε και το e-tron να έχει αναλογία βάρους 42:58 ίδια με αυτή του R8 V10. Η χωρητικότητα των μπαταριών είναι 53 KWh και δίνει την δυνατότητα στο supercar να έχει αυτονομία 250 χλμ. Η επαναφόρτιση τους γίνεται μέσα σε 6 έως 8 ώρες μέσω απλής οικιακής πρίζας ενώ με χρήση ταχυφορτιστή ο χρόνος αυτός μειώνεται στις 2.5 ώρες

Φυσικά το αυτοκίνητο είναι τετρακίνητο αλλά “by default” η κίνηση μεταφέρεται κατά 70% στους πίσω τροχούς, φυσικά σε περιπτώσεις που χρειαστεί, η κίνηση μπορεί να μεταφερθεί στον τροχό που χρειάζεται, ώστε να αποκτήσει το αυτοκίνητο ξανά πρόσφυση. Η Audi εφοδίασε επίσης το e-tron με ένα σύστημα “Torque Vectoring” το οποίο επιτρέπει στο supercar να εξαλείψει τα φαινόμενα υπόστροφης και υπερστροφής.

Η παραγωγή του θα περιοριστεί στις 1000 μονάδες με την τιμή του να κυμαίνεται γύρω στις €100.000. Φωτογραφίες και δηλώσεις τον ανθρώπων της Audi στο δελτίο τύπου που ακολουθεί

Audi R8 e-tron: A look inside the development workshop

  • quattro GmbH builds technology platform at satellite site in Biberach
  • Werner Frowein, Managing Director of quattro GmbH: “The staff is highly skilled in small series production.”

The first all-electric Audi will be built at the Neckarsulm site, with a small production run of the R8 e-tron sports car to hit the roads in late 2012. quattro GmbH is currently building the first technology platform for the electric model at the Neckarsulm plant’s satellite site in Heilbronn-Biberach. Specially qualified employees are borrowing from the series production of the successful Audi R8 mid-engine sports car as they assemble the R8 e-tron at the development workshop.

The 122nd Annual General Meeting of AUDI AG in Neckarsulm gave business and product journalists their first opportunity to look inside the development workshop for the Audi R8 e-tron.

“With the R8 e-tron, we are showing how inspiring electric mobility can be. Every system in this car has been tuned for maximum performance and range,” says Franciscus van Meel, Head of Electric Mobility Strategy at AUDI AG. “The R8 e-tron is a very important project for Audi because the competence and experience we glean from it will later flow into the large volume production of electric automobiles.” The expectation is that e-tron will become a synonym for advanced electric mobility, just as the term “quattro” today stands for pioneering all-wheel drive. “We want to be the leading premium manufacturer of electric vehicles by 2020,” says van Meel.

Systematic lightweight construction is one of the key preconditions for efficiency and range in electric vehicles. The Audi development engineers are therefore drawing on one of the company’s core competences for the R8 e-tron: The body is aluminum; thanks to Audi Space Frame technology (ASF), it weighs barely more than 200 kg (441 lb). The lightweight body is an important reason why the R8 e-tron weighs in at just 1,600 kg (3,527 lb).

Employees at the Pre-Production Center in Neckarsulm and quattro GmbH are currently building the first technology platforms for the electric car. “The successful production of our Audi R8 high-performance sports car has given the employees of quattro GmbH a high level of competence in the area of small production runs and sports car manufacture,” explains Managing Director Werner Frowein.

The aluminum body of the technology platform is being built in conditions very close to those for volume production in the body shop for the R8 mid-engine sports car. Specific assemblies for the electric model, such as the center tunnel, are being produced by the Pre-Production Center in Neckarsulm. The R8 e-tron also goes through the coating process with the volume model. The technology platform is then sent to the satellite site in Heilbronn-Biberach for final assembly. “The production process is designed so that we can exploit synergy effects from R8 volume production,” explains Frowein.

For example, the sophisticated logistics concept that supplies the R8 factory with parts is also used for the body of the technology platform. Pre-picked components are delivered to the employees in “shopping baskets.” The parts are installed in the vehicles in a defined sequence in four cycles. “Small-series production places great demands on our employees,” says Frowein. This is why the development workshop is staffed with experienced employees who worked in R8 series production, where they gleaned key competence in small-series production.

“The development workshop staff are specially qualified for high-voltage vehicles,” explains Andreas Heine, quattro GmbH project manager for the body of the R8 e-tron. They are trained in three stages – depending on their function and technical training – to work with the high-voltage technology. The basic level is sensitization for driving and working on high-voltage vehicles. The training then builds on this to qualify the workers as electronics experts for defined activities. Finally, the extended training as Certified Electronics Specialists for Automotive Technology provides the employees with the expertise required to perform the complete range of activities associated with high-voltage models.

AUDI AG is investing more than €5 billion in the two German sites at Ingolstadt and Neckarsulm between 2011 and 2015. A majority of this investment will flow into the development of new products and into future technologies such as electric and hybrid drive systems.

The future of mobility – the history of the Audi R8 e-tron

September 2009 Audi presents the e-tron high-performance sports car with all-electric drive at the Frankfurt Motor Show. With 230 kW (313 hp) and 4,500 Nm (3,319 lb-ft) of torque, the two-seater accelerates from 0 to 100 km/h (62 mph) in 4.8 seconds.

June 2010 quattro GmbH in Neckarsulm is chosen to build the R8 e-tron because of its competence in the areas of small-series production and the manufacture of high-performance sports cars.

July 2010 The Audi R8 e-tron wins the Silvretta E-Auto Rally. The two-seater beat 23 other electric cars in the three-day race covering 167.5 kilometers (104 miles).
