For the first time in over a decade, the IndyCar Series field will not be made up of identical cars. Aerodynamic development has opened up for the new season, although usually it’s the engine developers who take the lead rather than the teams themselves.

Chevrolet and Honda have produced the new aero kits and it’s up to the teams themselves to choose what parts they use.

A new era of Technical Regulations

The add-ons are a mixed bag from an aesthetic point of view, the possibility of different cars using different parts for their aero kits will introduce a new element of variety to the series at least in terms of how the cars look.

Will this have an effect on the competition? A major attraction of the IndyCar Series since the current chassis was introduced in 2012 was how close and competitive the racing was. A different champion was crowned every year and 52 races with the Dallara DW12 chassis has seen 17 different winners, more than twice Formula 1 has managed over the same period.

The first pre-season test with the new body kits, however, showed encouraging signs that the field will remain close. The top 17 were covered by one second in the final test at Barber Motorsport Park.

The cars are visibly faster both on camera and on the stopwatch due to the new aero kits generating a lot more downforce. Reigning World Champion for Team Penske, Will Power, beat his pole position time from last year’s race by a full second. This is despite other changes to the cars intended to control speeds and prevent them from launching in the event of a high speed spin.

Testing suggested that Chevrolet may start the season with a performance advantage over Honda. Many in IndyCar Series paddock believes that the power-to-grip ratio should have favoured engine horsepower over more downforce.

The 2015 Verizon IndyCar Series Season was meant to begin a few weeks ago in Brasilia but it was cancelled by its promoter. It has, however, ensured that the new aero kits will be ready for the first round in St Petersburg this weekend.
