Martinsville II

The Martinsville II NASCAR Cup Series race, officially named the Xfinity 500, represents a critical moment in the NASCAR playoffs. This race at Martinsville Speedway determines which drivers advance to compete for the championship. The 2026 edition continues the long tradition of high-stakes competition at America's oldest track still hosting NASCAR Cup Series races.

Martinsville Speedway Circuit Details

Martinsville Speedway sits in Ridgeway, Virginia, near the city of Martinsville. The track measures just 0.526 miles in length, making it the shortest circuit on the NASCAR Cup Series schedule. Its distinctive shape has earned it the nickname "The Paperclip" due to long straightaways connected by extremely tight, hairpin turns.

The track features 11 to 12 degrees of banking in the corners and completely flat straightaways. This layout creates unique challenges for drivers and teams. Martinsville Speedway uses a special surface combination: asphalt covers the straightaways while concrete paves the lower lanes of the corners. This concrete withstands the intense wear from racing tires and Virginia's harsh winter weather better than asphalt.

Race Format and Competition

The Xfinity 500 runs for 500 laps, covering 263 miles of racing. The short track length means drivers complete laps quickly, creating intense, close-quarters competition. Track position matters greatly at Martinsville Speedway because passing opportunities are limited. Drivers often must make aggressive moves to advance their positions.

The 2026 Martinsville II event will feature the full field of NASCAR Cup Series competitors. Championship-contending teams from Chevrolet, Ford, and Toyota will battle for one of the final spots in the Championship 4. The race brings together the series' top drivers and multi-car organizations in a decisive playoff round.

NASCAR Next Gen Car Technical Specifications

The NASCAR Cup Series uses the Next Gen car, introduced in 2022. This Generation 7 car was built to promote closer racing, reduce team costs, and increase connections to production vehicles.

Chassis and Body

The Next Gen car uses a steel tube frame with an integrated safety roll cage. Front and rear clips bolt onto the center section. The body consists of composite materials that offer improved durability and easier repairs. Teams can replace individual panels instead of entire body sections. Each manufacturer fields a distinct body style: Chevrolet runs the Camaro ZL1, Ford uses the Mustang, and Toyota campaigns the TRD Camry.

Engine and Performance

A 5.86-liter naturally aspirated V8 engine powers the Next Gen car. At short tracks like Martinsville Speedway, the engine produces approximately 670 horsepower. The car uses a 5-speed sequential manual transmission with one reverse gear. This transmission requires drivers to shift manually using a gear stick, adding another dimension to race strategy and driver skill.

Suspension and Wheels

The Next Gen car features independent rear suspension with 5-way adjustable Öhlins TTR dampers. This system replaced the solid rear axle used in previous generations. The car rides on 18-inch forged aluminum wheels wrapped in lower-profile Goodyear tires. A single lug nut secures each wheel instead of the traditional five-lug system.

Weight and Aerodynamics

The minimum car weight is 3,200 pounds without driver and fuel, increasing to 3,400 pounds with both. Aerodynamic features include a stepped front splitter, hood vents, redesigned side skirts, and a rear diffuser. For short track configurations like Martinsville Speedway, teams use a 4-inch rear spoiler to reduce downforce and allow closer racing.

Martinsville Speedway History

H. Clay Earles founded Martinsville Speedway in 1947. The track hosted its first race on September 7, 1947, before NASCAR's official formation. Martinsville joined the NASCAR schedule in 1949, hosting a Cup Series race on September 25, 1949, won by Red Byron. The track holds a unique distinction: it has hosted NASCAR Cup Series races every year since the division began in 1949, making it the only track with this continuous history.

The track started as a dirt oval. In 1955, workers paved the surface with asphalt. The current concrete-and-asphalt combination was added later to improve durability in the corners. In 2017, Martinsville Speedway installed permanent lighting, expanding race scheduling options after successful temporary lighting tests beginning in 2005.

Unique Track Characteristics

Several features make Martinsville Speedway distinctive among NASCAR Cup Series venues. The track's short length creates constant action as the field circulates quickly. The tight turns and flat corners demand heavy braking and precise throttle control. Cars run close together, often making contact during passing attempts.

Since 1964, race winners at Martinsville Speedway receive a grandfather clock instead of a traditional trophy. This award honors Martinsville's furniture manufacturing heritage. Richard Petty won 12 grandfather clocks during his career, the most of any driver.

Martinsville Speedway is also famous for its concession-stand hot dogs, which have become a beloved tradition among race fans. The combination of hard racing and unique track characteristics makes the Martinsville II race a defining moment in the NASCAR Cup Series season. The 2026 edition promises to deliver the intense competition that has made this race a fixture in NASCAR playoff history.
