About riley 


“I’m so excited to be involved in the continuation of the MkIV.
Being a part of a Riley program with both Bill and Bob is always great, and I am looking forward to seeing these awesome cars back on track.”

-JIM MATTHEWS


“It is amazing and somewhat humbling to even have the chance to be involved in continuing the legacy of such an iconic car. For sure, this has always been one of my favorite race cars, and to be able to continue producing it makes me very proud.”

-BILL RILEY

To continue a legend

Start with legendary people

In the 1960s, a young design engineer named Bob Riley was working for Kar-Kraft in Detroit. Ford had commissioned Kar-Kraft with a top secret project that eventually went on to win Le Mans. Since those early days, Bob, and eventually his son, Bill, would go on to design, engineer and build cars that have been dominant forces in nearly every major racing series, including NASCAR, IndyCar, Grand-Am, IMSA and Trans-Am. Add in the fact they are responsible for thirteen overall 24 Hours of Daytona victories and more when including class wins, and you realize why Riley is perfectly suited to carry on the continuation of the MkIV project.

The partnership between Bob & Bill Riley and long-time friend and customer, Jim Matthews carries on the legendary tradition first started in the 1960’s that Bob himself was closely involved in.

“The original MkIV was developed by a group of individuals that wanted to win. We all would stop everything to get something designed, fabricated and tested quickly. We were not  afraid of the hard work and the enthusiasm to achieve those successes with the MkIV was without question. That is the same philosophy that the Riley staff has had from the beginning and that same enthusiasm will go in to each MkIV continuation that leaves here.”
