Roger Penske spent part of Tuesday walking Indianapolis Motor Speedway, using a cool, sunny day to look over the historic venue that will soon be his.

Mari Hulman George, the "quiet pioneer" of auto racing who was instrumental in the expansion of Indianapolis Motor Speedway and became known to millions of fans over the years as the one who ordered countless drivers to start their engines before races, died Saturday. She was 83.

Hulman George, the speedway's chairman of the board emeritus, died in Indianapolis with her family at her side, the speedway said in a statement.

INDIANAPOLIS (AP) — Ed Carpenter spends the entire year thinking about the Indianapolis 500, even though he runs a full-time IndyCar effort with other drivers in the seat the rest of the year.

The race is quite literally in his blood: He is the stepson of Tony George, whose family has owned Indianapolis Motor Speedway for decades and who founded the Indy Racing League in the 1990s.

That explains why Carpenter had such a hard time processing things Sunday.
