Allianz Safety Focus - New Era

The new regulations have not changed the basic task of exploiting the rules as much as possible and so gaining a valuable advantage even before the season starts. “We set ourselves a target of a top engine speed of 20,000rpm,” said Alex Hitzinger, “and we’ve managed that.” The new engine for the Williams FW28 drove its first kilometres on the test stand on October 12, 2005, and the first test drives on the track were held just five weeks later. Despite the engineers’ love of detail, it was important to keep an eye on the bigger picture, such as delivering a compact, mechanical package to the aerodynamic engineers to leave them as much freedom as possible for their work.

Because a V8 is much shorter than a V10 and by its nature also needs less cooling, it was possible to visibly streamline the new car at the rear, which helped the aerodynamics.

New engine concepts are also in the pipeline for road car production. “The increase in fuel prices will be a major driving force in the next few years for the development of engine technology,” said Dr. Christoph Lauterwasser from the Allianz Centre for Technology (AZT). On the one hand, that means low-consumption, efficient engines, which explains the continued trend towards diesel vehicles, whose engines are about 30% more efficient than comparable petrol engines. But, on the other hand, there is a growing proportion of hybrid vehicles that combine a combustion engine with an electric engine and produce excellent fuel consumption and lower CO2 values. “The significance of alternative fuels like natural gas and biofuels will increase all over the world,” said Lauterwasser. “If you also consider the tests on hydrogen vehicles and fuel cells, it’s easy to see that we are heading towards a new level of variety under the bonnet.”

In Formula 1, the engine capacity was reduced from 3.5 to 3 litres for safety reasons in 1995. However, that did not interrupt the power explosion, and to halt it further, the Fédération Internationale de l’Automobile (FIA) then decided to impose more restrictions: for instance, in the 2004 season, each engine had to last a full grand prix weekend, and since 2005 it has only been permissible to use one engine for two racing weekends. Of course, all these rules are open to exceptions: with the permission of the FIA, the smaller teams will still be permitted to use ten-cylinder engines, but their engine speed must be limited to a maximum of 16,700rpm.

The new engine concept will also affect the racing strategy of the teams, because at the end of the day a V8 at full power consumes about 15% less fuel than a V10. That will either shorten the distances that can be driven between pit stops or it will shorten the pit stops themselves, because the car does not need as much fuel as before. The strategists are already racking their brains. According to Hitzinger, “there will certainly be lots of changes in terms of the tactics.”

Allianz Safety Check: Bahrain International Circuit – by Mark Webber:

“On this track, the latest safety standards have been implemented beautifully. Especially in the run-off zones, which are designed so generously that a driver error doesn’t immediately lead to an accident. We will lose time, but we can carry on driving. Even if one of us makes a mistake in one of the fast sections, there is always enough space so you don’t immediately hit a wall. It was also a good idea to cover the areas to the left and right of the track with grass: that stops cars that are driving past from swirling sand and dust up on to the track.”
