R27 is a step forward in overall quality - Densham

The ING Renault F1 Team's Chief Designer of the new R27, Tim Densham, doesn't like to over-complicate things when it comes to producing an F1 car. Here's his down to earth take on Renault's new championship challenger.

"R27 is our second-generation V8 car, following on from last year’s championship-winning R26. That clearly gave us a very solid platform to work from, and we have honed it according to the same in-house design philosophy that has worked very successfully in recent seasons."

"The most important regulation changes have been new impact tests at the front, rear and side of the car. These have required some fairly intensive design work to integrate them into the overall packaging at the car, particularly when it comes to the rather bulky side intrusion protection panels. The second important element for the design process was the shift to Bridgestone tyres. We had an early idea of the tyres’ basic characteristics, and began the project with the aim of making the car’s weight distribution as flexible as possible. The subsequent tyre data and track testing confirmed that we needed more weight towards the front of the car in order to get the most from the tyres. Much of our design work has focused on saving weight in order to give the race engineers the ability to find the optimum handling characteristics for every circuit."

"I think that it proved a little easier, because in 2006 we were designing a car for a brand new engine. For 2007, we were starting with a known quantity, and we understood a lot more about the vibration levels involved, and how components needed to be designed to cope. Our improved understanding made the process easier. The second important factor was that we chose to run a hybrid car during pre-Christmas testing. This meant that the rear end of the car was effectively ready by late November, which helped us balanced the workload during the winter months."

"As always, our goal has been to push hard in the traditional development areas: we have tried to improve the stiffness of the package, to save weight where we can – and to package the car as tightly as possible in order to give our aero team the maximum opportunity to generate performance gains. In general terms, the R27 is a car in which we have taken a good step forward in overall engineering quality."

"This is a programme that has been up and running for quite a long time. We ran a prototype version of the gearbox in testing throughout the season, and were able to integrate the information from that prototype into the definitive version. That gearbox ran for the first time during the final tests of 2006, and performed well, in spite of some normal teething problems."

"I think the new car features as many improvements relative to its predecessor, as R26 did relative to R25. Of course, some areas have not changed, but we have targeted our design and development resources on those areas that can bring us maximum performance advantage. And we are pushing very hard on development already, with a continuous stream of improvements already planned. That was a strength in 2006, and we are aiming to maintain that through the new season."

"We have deliberately maintained a consistent mechanical layout, as this will allow the trackside teams to find their feet very quickly – and the same will be true for the drivers. Our recent cars have all been very driveable, and they have allowed the drivers to really push to the limit and have confidence in its reactions. We hope this will be an advantage in the close, competitive environment during 2007."
