Iowa Speedway Uses First SAFER Barrier in New Construction

Iowa Speedway, which hosts the IndyCar Series and Indy Pro Series this weekend for the first time, became the first track to be constructed using the SAFER (Steel and Foam Energy Reduction) Barrier developed by the Indy Racing League and the University of Nebraska.

The SAFER Barrier was first installed in all four turns at the Indianapolis Motor Speedway in 2002. Subsequent installations of the system around the globe have been retro-fit to existing concrete walls of racetracks.

That changed with the design and construction of Iowa Speedway. At the suggestion of Indy Racing League senior technical director Phil Casey, the track became the first to install the new Alternative Backup Structure around the entire perimeter of the 0.875-mile racing surface. The new system incorporates anchored steel posts with bundles of closed-cell polystyrene foam between them and the (40-inch tall, 28-feet long) square structural steel tubing (8 inches each, stitch welded at seams every 12 inches) that comprises the “soft wall.”

“Racetracks that are already built have cement walls, so it was easy to put the SAFER Barrier and the foam against the cement walls,” Casey said. “If you have temporary circuits like road courses or building a new racetrack, you need a way to put up SAFER Barriers and it’s so expensive to put up cement walls (about $4 million on a mile racetrack). Consequently, the Alternative Backup Structure saves about a third of the cost.”

All 12 ovals on the IndyCar Series schedule contain the SAFER Barrier.

Impacts in early races at the speedway have supported data of development and testing by the University of Nebraska group.

“It’s very strong,” Casey said. “There was considerable testing. A few ARCA cars and Silver Crowns have hit it and it performed well.”

A similar structure – a steel post imbedded in a concrete barrier with the foam and steel tubing fronting it -- could soon be incorporated in sections of road/street courses (selected corners) and ovals (pit lane walls, inside racetrack).

“Any new facility or road course that needs it in high-speed corners, the recommendation would be to put the latest generation in,” Casey said.

The sanctioning body also is working with the University of Nebraska team on development of a pit lane attenuator system (nose of pit lane wall), which is entering the testing phase. Upon impact, the device compacts (slides on a center rail) to absorb the energy.

“There is always room for development,” Casey said.

Robert Kubica Released from Hospital with Minor Injuries

Poland's Robert Kubica emerged from a Montreal hospital on Monday to say he had recovered from minor injuries sustained in a horrific crash in Sunday's Canadian Formula One Grand Prix and hoped to race next weekend in Indianapolis.

On Monday, Robert Kubica said he remembered "nearly everything" about Sunday's crash which shattered his car.

"As you see I'm quite in good shape and I'm hoping [to be] going to Indianapolis if the doctors will say OK for my driving," Kubica told reporters outside Montreal's Sacre-Coeur Hospital.

"I feel very good. I was very lucky -- big accident, but fortunately, nothing hurt," he added after walking gingerly down the steps of the hospital.

Kubica said he remembered "nearly everything" about the crash in which he suffered a slight concussion and sprained ankle.

The accident occurred when the 22-year-old BMW Sauber driver's car made contact with the rear wheels of Jarno Trulli's Toyota on the approach to the hairpin on lap 27 on the Gilles Villeneuve circuit and his car took off, flying through the air and slamming into a concrete wall before barrel-rolling across the track.

The crash shattered Kubica's car to the extent that his feet could be seen through the sheared off front end of the vehicle.
