Ripple Effect

When testing the new Indy car at Indianapolis Motor Speedway last fall, drivers James Hinchcliffe and Scott Dixon reported bumps on four areas of the track, not necessarily visible to the naked eye, but clearly felt at 200 mph. Engineers took core samples down to the iconic bricks and found that the culprit for at least one of the irregularities was a missing line of bricks that had buckled and was replaced with asphalt around 1939. Over many freeze/thaw cycles, the new material expanded and contracted differently than the surrounding brick and mortar, causing a ripple to form. Areas of concern have been smoothed in hopes that the curr

THE CARS

Welcome to the 2026 Road & Track Performance Car of the Year. I am delighted to bring you the following work of a select team of pros at R&T. The coverage of this year's PCOTY spread out over the next 28 pages is the result of nearly a year of planning, a week of long but glorious days, and a not inconsiderable amount of money. That said, before you flip furiously to the final page of this presentation to see what won, or head to roadandtrack.com to watch the Performance Car of the Year video and read the myriad other stories about these nine cars, I ask that you hear me out on a couple of provisos.
