Source-derived summary

The 2019 IMSA SportsCar Championship (known for sponsorship reasons as the 2019 IMSA WeatherTech SportsCar Championship) was the 49th motor racing championship sanctioned by the International Motor Sports Association (IMSA) (which traces its lineage back to the 1971 IMSA GT Championship). It was the sixth season of the United SportsCar Championship and fourth to be held under the name as the IMSA SportsCar Championship. It began on January 26 with the 24 Hours of Daytona, and ended on October 12 with the Petit Le Mans. The 2019 season marked the 50th anniversary since the founding of the International Motor Sports Association.

Series news

NBC Sports Group took over from Fox Sports as the series' official broadcaster. Coverage alternates between local NBC stations, NBC Sports Network, CNBC, and livestreams.

Michelin increased its IMSA involvement by becoming the sole official tire supplier of the series, following the departure of Continental Tire at the end of 2018.

As part of a plan to attempt to cut costs for the series' GT Daytona (GTD) class, the 2019 season featured a new support championship called the WeatherTech Sprint Cup. The championship was held for the GT Daytona class at the sprint events of the calendar.

After an eleven-year partnership, Tequila Patrón ended their involvement with IMSA altogether at the end of the 2018 season.

Editorial analysis

Why this record matters

The phrase “49th season of the racing series organized by IMSA” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 13, 2026. The linked authority identifier is Q56042836. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2019, 1971 and 2018.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
