Τελικά η Audi δεν πήγε το R8 e-tron στο Nürburgring για δοκιμές εξέλιξης, αλλά για να πάρει το ρεκόρ του ταχύτερου γύρου από ηλεκτρικό αυτοκίνητο στη Πράσινη Κόλαση. Το R8 e-tron με οδηγό τον Markus Winkelhock σημείωσε χρόνο 8:09.099, συντρίβοντας το προηγούμενο ρεκόρ του E-Ra, το οποίο είχε σημειώσει το χρόνο 8:42.72.

To R8 e-tron διαθέτει 4 ηλεκτροκινητήρα απόδοσης 230 kW (313 άλογα) με 820 Nm ροπής. Ζυγίζει 1.780 κιλά και τα 0-100 χλμ/ώρα τα κάνει σε 4.8 δευτ με την τελική ταχύτητα να περιορίζεται ηλεκτρονικά στα 200 χλμ/ώρα, αλλά για τις ανάγκες του ρεκόρ, η τελική περιορίστηκε στα 250 χλμ/ώρα. Η Audi έκανε δύο γύρους και με τελική ταχύτητα περιορισμένη στα 200 χλμ/ώρα όπου σημείωσε χρόνους 8:30.873 και 8:29.096.

Η χωρητικότητα των μπαταριών είναι 49 KWh και δίνει την δυνατότητα στο supercar να έχει αυτονομία 215 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. Οι υδρόψυκτες μπαταρίες λιθίου βάρους 550 κιλών έχουνε τοποθετηθεί πίσω από τα καθίσματα ώστε και το e-tron να έχει αναλογία βάρους 42:58 ίδια με αυτή του R8 V10.

Τo αυτοκίνητο είναι τετρακίνητο αλλά “by default” η κίνηση μεταφέρεται κατά 70% στους πίσω τροχούς και 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. Μόλις 1.000 αυτοκίνητα θα βγούνε στη παραγωγή με την τιμή του να κυμαίνεται γύρω στις €100.000.

World record for the Audi R8 e-tron: with 8:09.099 minutes at the Nürburgring

  • Superior peak performance for electric-drive production vehicles
  • Racing driver Markus Winkelhock piloted the new electric sports car with 280 kW output
  • Michael Dick: “To us, electric mobility means dynamics and driving pleasure”

The future of electric mobility at Audi is highly dynamic: The R8 e-tron has set a world record for a production vehicle with an electric drive system on the Nürburgring Nordschleife – the toughest test track in the world. Racing driver Markus Winkelhock piloted the high-performance, all-electric-drive sports car around the demanding 20.8-kilometer (12.92-mile) track in 8:09.099 minutes. With this Audi has achieved yet another milestone in its history, following overall wins at the 24-hour races at the Nürburgring and Le Mans.

“The R8 e-tron has given a magnificent demonstration of its potential on the toughest race track in the world,” said Michael Dick, AUDI AG Board Member for Technical Development. Dick, who completed a fast lap himself in the R8 e-tron, added: “The record-setting drive confirmed that we are on the right track. To us, electric mobility has never been about sacrifice, but rather is about emotion, sportiness and driving pleasure.”

A comparison with the current record lap driven by a combustion engined production car shows just how impressive the 8:09.099-minute time really is. The record time of 7:11.57 minutes was achieved with a Gumpert Apollo Sport, which is powered by a 515 kW (700 hp) Audi V8 gasoline engine.

The drive system of the Audi R8 e-tron that Markus Winkelhock drove to the world record corresponds in every detail with that of the production model that will come on the market at the end of the year. Both of the car’s electric motors generate an output of 230 kW and 820 Nm of torque; more than 4,900 Nm (3,614.05 lb-ft) are distributed to the rear wheels nearly from a standing start.

The Audi R8 e-tron accelerates from zero to 0 to 100 km/h (62.14 mph) in just 4.6 seconds. Its top speed is normally limited to 200 km/h (124.27 mph); 250 km/h (155.34 mph) was approved for the record-setting lap.

The R8 e-tron’s rechargeable lithium-ion battery stores 49 KWh of energy – enough for a distance of about 215 kilometers (133.59 miles). Its “T” shape allows it to be installed in the center tunnel and in the area between the passenger compartment and the rear axle. It is charged by energy recovery during coasting and braking. The ultralight car body of the Audi R8 e-tron is made primarily of aluminum, along with CFRP components; this is a main reason why the high-performance sports car weighs just 1,780 kilograms (3,924.23 lb), despite the large battery.

In order to further underscore the production-relevance of the R8 e-tron and the capability of its drive technology, Audi has set another record on the Nordschleife in addition to the single lap record time. Immediately afterwards, Markus Winkelhock drove two fast laps in one go in a second R8 e-tron that was limited to 200 km/h (124.27 mph). At 8:30.873 and 8:26.096 minutes, both laps were well under the important nine-minute threshold.

“The record drives were a fantastic experience for me,” said Markus Winkelhock. The 32-year-old, who lives near Stuttgart, has a high standard for comparison – the Audi R8 LMS ultra, in which he, along with Marc Basseng, Christopher Haase and Frank Stippler, won the 24-hour race at the Nürburgring a few weeks ago.

“Of course, the R8 e-tron is a production car, not a racing car with the assistance of aerodynamics,” Winkelhock emphasized. “But with its low center of gravity and rear biased weight distribution, it brings with it a lot of sporty qualities. The torque with which the electric motors propel the car uphill beats everything that I know – even if they make hardly any noise in the process, which at the start was really a completely new experience for me. In places where I really need traction, the torque vectoring – the displacement of the torque between the powered wheels – really helps me.”

Michael Dick proudly summed up events after the record-setting drive at the Nürburgring. “Within just a few weeks we’ve taken on some big challenges and in the process we’ve shown that we are at the forefront with all of our drive concepts,” he said, adding:“We won the 24-hour race at the Nürburgring in May in the Audi R8 LMS ultra with a ten-cylinder engine.

In mid-June we triumphed at the 24 Hours of Le Mans with the Audi R18 e-tron quattro – the first overall victory for a hybrid-electric vehicle in the toughest race in the world. And now we’ve set another record with the all-electric-drive R8 e-tron on the most demanding track there is.
