A racecar driver from Redding was killed when his car crashed into a wall at the Calistoga Speedway on Saturday night, Calistoga Fire Chief Steve Campbell said.

Napa County sheriff's Capt. Tracey Stuart identified the driver as 20-year-old Tyler Wolf. He died at 9:56 p.m. at St. Helena Hospital, Stuart said.

The crash happened while at least 20 cars were racing on the half-mile dirt track during the 25-lap main event celebrating the 75th anniversary of the Speedway, Campbell said.

Wolf's car hit a wall along Turn 2 around 8:30 p.m., Campbell said. Wolf was wearing a helmet and seatbelt when he crashed, and his car did not catch fire.

Saturday's race was the last of six races this year at the Speedway, where cars can reach speeds of up to 150 mph, Campbell said.

The last fatal crash at the raceway happened in 1982, Campbell said.

An autopsy on Wolf was scheduled for Monday.
