What: Big Machine Music City Grand Prix / Race 13 of the 2023 NTT IndyCar Series

Where: Nashville, Tenn. — 11-turn, 2.1-mile temporary street course 

When: Sunday, Aug. 6, noon ET (green flag 12:30pm ET)

When it comes to the NTT IndyCar Series, there’s a well-proven mantra: “It’s IndyCar — anything could happen.” And that’s never truer than in the Big Machine Music City Grand Prix.

In IndyCar, the margins between triumph and disaster, confidence and confusion, and winning and losing, are fine ones, but they’re seldom finer than on a weekend in downtown Nashville, Tennessee. 

The 2.1-mile street course that zips past the Nissan Stadium, home of the Tennessee Titans NFL team, and crosses the Cumberland River via the Korean War Veterans Memorial Bridge, is one of the most distinctive race tracks in the world, and the first two IndyCar races there have been suitably memorable. 

The first, in 2021, saw Chip Ganassi Racing’s Marcus Ericsson caught up in an accident in the opening laps — one violent enough to lift his nose almost to the vertical after running into the rear of Sebastien Bourdais’ AJ Foyt Racing machine. But after limping to the pits for makeshift repairs, then suffering a drive-through penalty, and spending the remainder of the race with askew steering and bent suspension, the Swede came home the winner.

Remarkably, another Ganassi driver, ageless master Scott Dixon, won last year’s Nashville race (below) after suffering early damage and dropping way down the order. He shrugged off the seemingly debilitating effects of major damage to his car’s floor and multiple early pit stops to run a very long final stint. Despite extremely worn tires, he survived a late-race restart to hold off fellow Kiwi and polesitter Scott McLaughlin of Team Penske on the run to the checkered flag and his 53rd career IndyCar win.

Can the third Music City GP produce similar drama this weekend? You better believe it. It’s as if track designer Tony Cotman of NZR Consulting devised the layout in the heart of country music land to throw as many challenges as possible at the drivers, engineers, engine manufacturers and tire supplier Firestone. 

Damper setup is key as the cars pitter-patter over the bumps in the braking zones, and the differentials need to help a driver rotate the car on turn-in, yet be forgiving enough to help settle it and allow the outside rear to dig in rather than spin away its 750hp-plus. The Firestones are worked hard too, the green, guayule-infused sidewalls of the alternate compound and the black “primaries” providing enough stiffness to maximize the footprint, but enough flexibility to work with the suspension and grip the pavement even when lightly loaded or on off camber turns. 

The engines, too, must provide enough lowdown torque to push the cars hard out of the tight corners, yet the power must arrive progressively enough not to leave the rear tires scrabbling for grip and burning off their shoulders. The long “straight” of the gently curving bridge, particularly on the return leg from Turn 8 to Turn 9, sees the engine working hardest, from a slow (greater than 90-degree) right-hander taken at 47mph onto a flat-out blast that sees the cars reach 177mph
