IndyCar has unveiled its next-generation race car, the IR-28, which will replace the current chassis when it enters competition in 2028, ending a 15-year run for the existing model. The reveal, made on Tuesday, marks the biggest overhaul of the series' cars in over a decade, with the new design retaining recognisable IndyCar characteristics while introducing updated styling and technical changes.

While the current car has benefited from ongoing technological and safety upgrades throughout its lifespan, the chassis itself has remained fundamentally unchanged since it was introduced roughly 15 years ago. The new IR-28 is intended to modernise the series' equipment ahead of its 2028 debut, though full technical specifications have yet to be detailed.
