Bay Area natives and brothers Ed and Martin Lauber are in the field for the sixth annual Classic Sports Racing Group Charity Challenge, which returns to Infineon Raceway Saturday and Sunday in Sonoma. There will be more than 200 historic race cars with drivers racing throughout the weekend on the 12-turn, 2.52-mile road course.

Ed Lauber is a resident of Redwood City. Martin Lauber has residences in Napa and Mill Valley. They will be competing in a 1965 Alfa Romeo Spider Veloce and 1965 Alfa Romeo Sprint GT.

Big brother, Ed, taught Martin all about cars as they were growing up, but now the student is schooling the teacher on track.

Martin acquired two vintage Alfa Romeo race cars, one for him and one for his brother. Martin races several times a year, but Ed, a father of two young boys, only comes out a few times a year. But the two thoroughly enjoy racing together.

The brothers have also found success off of the track. Martin is the founder and creative director of a San Francisco-based marketing agency, Swirl Integrated Marketing. Ed is the founder and general manager of Auction City, a wholesale auto auction open to the public in Redwood City.

More than 200 vintage race cars will grace the road course over the weekend. Some of the featured cars include 600-plus horsepower CanAm Series cars. There will also be more than 200 vintage open-wheel, production and sports-racing cars from the 1930s through 1970s. There are many well-known groups, including Ferrari, Aston-Martin, Porsche, Alfa Romeo, Shelby, Corvette, MG and Jaguar.

There will be several timed feature races each day.

Local enthusiasts from Porsche, Ferrari, Audi, Alfa Romeo and other clubs will display their cars on the paddock.

All proceeds from the event will benefit Speedway Children’s Charities, the charitable arm of Infineon Raceway. Over the last five years, CSRG has generated more than $400,000 for SCC.

Admission is $20 for adults (weekend pass) and $10 for youths (ages 12-16). Children 12 and under will be admitted free of charge.

There is no charge for parking.
