Delphi Pioneers New Racing Technologies With Pi Research

Products Improve Data Accuracy and Help Teams Better Understand Racecar Performance

TROY, Mich., Dec. 3 -- Delphi Corp. said it is continuing to lead the race for advanced technology in motor sports with the introduction of groundbreaking sensor technology developed in conjunction with Pi Research, a world leader in motor sports electronics for nearly all racing segments including karting, stock and open-wheel.

The products, a three-axis angular rate sensor, a single-axis angular rate sensor, a three-axis accelerometer and a single-axis accelerometer uniquely feature built-in temperature compensation. Racecar temperatures can fluctuate between 32 and 158 degrees Fahrenheit, and that can warp data. The built-in temperature compensation in Delphi's products inhibits the effect those changing temperatures can have on data output, making the information more accurate. Engineers and crewmembers can use the more accurate data, along with input from the driver, to make changes to the racecar for better performance.

"In racing, accurate information is becoming more critical to the chase for the checkered flag and we are excited to be able to help teams through these enhanced sensor innovations," said William A. Lafontaine, Delphi's corporate director of media relations and marketing communications. "Working with Pi Research, a company known for setting the standard in motor sports electronics, to bring these technologies to the sport is a huge step in our efforts to meet the needs of the racing community and is a great opportunity to share research and development capabilities."

Delphi's three-axis angular rate sensor is the first of its kind to measure information on the car's roll, pitch and yaw, in one small package. The sensor, which measures 1.05" x 1.05" x 1.3" and weighs only 2.35 ounces, is usually mounted in the center of the vehicle to determine rotation in the x-, y- and z-axes. The single-axis angular rate sensor is 1.05" x 1.05" x 0.77" and weighs only 1.35 ounces while providing rotational rate data for a single axis.

Delphi's three-axis accelerometer measures acceleration in (Gs) in the x- y- and z-axes, while the single-axis accelerometer does the same for only one of the axes. Usually mounted in the center of the vehicle to show the forces on the car in all three axes, the three-axis accelerometer is a sleek 1.05" x 1.05" by 1.3" and weighs 2.35 ounces. The single-axis accelerometer is typically attached to a suspension component to show that component's movement during race conditions. It is 1.05" x 1.05" x 0.77" and weighs only 1.35 ounces.

Kelley Racing and driver Scott Sharp, sponsored by Delphi, have been testing the new sensors since the Motegi race earlier this year in Japan where Sharp took the checkered flag. "The output from Delphi's new sensors seem to be really helping us make better, and ultimately fewer, changes to the car in order to get maximum performance," said Tom Kelley, owner, Kelley Racing and president, Kelley Automotive Group.

The new sensor technology is key to advancement of Delphi's accident data recording technology. The sensors and associated circuitry design will be the primary driver in improvements such as size, weight, accuracy and reliability of Delphi's next-generation accident data recorder (ADR3) launching in 2005. Delphi currently provides its ADR2 to Formula 1, Championship Auto Racing Teams (CART) and the Indy Racing League (IRL).

Today, Delphi is the official electronics provider to the IRL and has been involved in open-wheel racing since 1988. A majority of the vehicles in the IRL are equipped with several of Delphi's racing products including the ADR2. Delphi has cooperated on several motor sports products with Pi Research since 1994.
