Bridgestone completes successful MotoGP tyre test at Phillip Island
Wednesday, March 5 2014
Phillip Island Circuit, Australia
Bridgestone slick compounds available: Front: Extra-soft & Soft. Rear: Hard (various test compounds - asymmetric)
Weather: Dry. Ambient 17-33°C; Track 22-52°C (Bridgestone measurement)
Bridgestone completed a successful three-day tyre test at Phillip Island, as the Official Tyre Supplier to MotoGP? met its objective of testing a range of new rear slick tyres to deliver safety, performance and durability for a full race-distance at the Australian Grand Prix in October.
Bridgestone brought two front and eight rear specifications of slick tyre to the test, with six of the rear slick specifications being brand new test tyres developed specifically for the Phillip Island circuit. Five riders; Ducati's Andrea Dovizioso and Cal Crutchlow, Repsol Honda's Dani Pedrosa, and Yamaha Factory Racing's Jorge Lorenzo and Valentino Rossi took part in the three-day test, completing a total of 861 laps.
The experimental rear slicks provided for the tyre test featured developments in compound, construction and profile technology in order to find the optimum solution for a circuit that is the toughest on rear tyres on the whole MotoGP? calendar. The first day of the test was used for initial testing of all six experimental tyres; the second and third days of the test were dedicated to race simulations on the tyres that were more found to be more suitable following analysis of tyre data and rider feedback. Out of the six experimental rear slicks provided, three specifications proved to be more promising both in terms of durability, performance, and rider feedback. These three rear slick options were tested extensively over the final two days of the test and the further positive rider feedback and data analysis acquired on these three options on the final two days means that they will form the basis of tyre development for the Australian Grand Prix in October.
The weather at Phillip Island was changeable over the three days, allowing Bridgestone to acquire tyre performance data in a wide variety of conditions. Track temperatures ranged from 22°C to 52°C and brief periods of rain were recorded on the final day of the test. The lower ambient and track temperatures on the final day of the test were a welcome change, as they allowed the riders to test the tyres in similar conditions to what can be expected for the Australian Grand Prix in October.
Bridgestone now heads to Qatar to support the final MotoGP? pre-season test of 2014 at the Losail International Circuit from March 7-9.
Shinji Aoki - Manager, Bridgestone Motorsport Tyre Development Department
"This was a very positive test for Bridgestone as we achieved all our objectives. I would like to thank the riders and teams for all their hard work over the three days, as without them we couldn't have achieved what we set out to do. Our primary focus was to find some suitable rear tyre options for this circuit, and out of the six experimental rear slicks we provided for the test, three options yielded some very encouraging results. These three rear slick options will now steer development for the race tyres we will provide for October's Australian Grand Prix and following a successful three days, we are confident of delivering an allocation of tyres that will last the full-race distance while maintaining very high levels of safety and performance."
Bridgestone tyre test comes to an end with Pedrosa in second
Repsol Media Service | Australia, Phillip Island Circuit | Wednesday 03/05/2014
Repsol Honda's Dani Pedrosa has completed the three-day tyre test in Phillip Island, signalling an end to his Winter testing schedule and a gruelling six days testing in the past eight days.
With weather conditions changing drastically from yesterday, air temperatures down by 13ºC and the track 20ºC cooler, Dani waited until 12pm to go out on track, as light rain threatened the cliff top circuit. Fortunately, the rain never came and Dani was able to follow Bridgestone's schedule. He recorded his fastest time of 1'29.458 on lap 18 and ended his day with a longer run of 14 laps, taking his total for the day to 32, and over the three days to 178 laps.
The next time Dani will be on track, he will be rejoined by his teammate Marc Marquez, for the first practice session of the season opening Qatar Grand Prix, on Thursday 20th March.
1:29.458, 32 laps, 142 km.
"Overall, this has been a positive three days. Today we tried to do another 20-lap race simulation with the second best tyre that we had. I didn't fully complete it, only managing 14 laps, because after so many days riding I had some neck ache. In any case, generally speaking it was a test that went well. We have enough data gathered not only for Bridgestone, but also for ourselves, so I think that it has been positive and now we shall try to rest up a bit. It's all about continuing our training now, with the first race in Qatar on the horizon."
IRTA tests at Phillip Island conclude for Ducati Team
Today was the third and final day of testing for the Ducati Team at the Phillip Island circuit. The Australian session had been organized by IRTA and Bridgestone with the specific aim of developing the Japanese tyres in view of the Australian Grand Prix in October, and it was reserved for the official teams of the three manufacturers taking part in the MotoGP World Championship.
Following the good results obtained at Sepang last week, in Australia the two Ducati Team riders were able to carry out the work requested by Bridgestone, which included an appraisal of compound, construction and profile technology, and race simulation, as well as a continuation of development work on the Desmosedici GP14 in ?Open' configuration. The tyres available for the three teams present at the tests were however the same for all.
After three days of intense work, Andrea Dovizioso concluded the test with an overall third fastest time of 1m29.387s, three-tenths of a second away from the quickest rider, while his team-mate Cal Crutchlow ended up fifth with a best time of 1m29.576s.
Andrea Dovizioso (Ducati Team #04) - 3rd (1m29.387s)
"Unfortunately I wasn't feeling at 100% these days, but when I was able to lap my feeling with the bike was good and so I'm pretty satisfied with this test at Phillip Island. We continued development work on the GP14 and on this track, which is very different to Sepang, we were again able to obtain results that make us feel confident for the future. Our pre-season tests have been quite positive and now I can't wait for the championship to start."
Cal Crutchlow (Ducati Team #35) - 5th (1m29.576s)
"The team worked great at Phillip Island. We had a lot of stuff to try for Bridgestone over the three days to evaluate the rear tyre. I'm happy enough to go away from here feeling positive at this circuit. At no point did I push for a one-off lap time over the three days, so I'm confident we could have made an improvement if we'd needed to but the test was about evaluating the tyres for Bridgestone and I wasn't taking any unnecessary risks."
Luigi Dall'Igna (Ducati Corse General Manager)
"For us it was important to show that we could also make progress at Phillip Island, on a track that is so different from Sepang in Malaysia. We also tried to do a race simulation, which is always very useful. I am quite pleased with the results, but in any case we still have a lot of work to do before becoming really competitive."
