Welcome to Porsche Ontario, where luxury, passion, and heritage come together to create an elevated automotive experience. As part of Kienle Motorsports, a specialized division of the Walter’s Automotive Group, we proudly continue a family legacy built on craftsmanship, integrity, and an unwavering love for the Porsche brand.
A Heritage of Excellence
Our story begins with Walter Kienle, who arrived in the United States from Switzerland in 1948. After serving in the U.S. Army and building a respected career as an automotive mechanic, he opened Walter’s Automotive Service in Riverside in 1960, setting the foundation for what would become one of Southern California’s most trusted automotive families. Today, Porsche Ontario carries that legacy forward with the same commitment to honesty, expertise, and personalized care.
A Destination for Porsche Enthusiasts
Porsche Ontario is more than a dealership. It is a community hub built by true Porsche enthusiasts for Porsche enthusiasts. Our team brings a deep appreciation for the engineering, artistry, and spirit behind every Porsche model. Whether you arrive in a new 911 or a cherished vintage air-cooled icon, you will be welcomed by people who share your passion.
Porsche Ontario is an Authorized Porsche Classic Service Center, one of the few in the region. This certification allows us to care for both modern Porsche vehicles and classic models with factory-approved tools, parts, and expertise. From routine maintenance to intricate restoration-level repairs, our master technicians provide meticulous service that preserves the performance, precision, and value of every Porsche.
Community, Events, and Connection
As a family-owned dealership, we are deeply invested in the community we call home. Through philanthropic partnerships, local involvement, and ongoing support of charitable organizations, we continue the Kienle family tradition of giving back.
We also believe in celebrating Porsche culture. Our regular Cars and Coffee gatherings and enthusiast-focused events bring together owners from across Ontario, Rancho Cucamonga, Chino Hills, Walnut, Los Angeles, and beyond. These experiences create lasting relationships and foster a community united by passion, design, and performance.
