What Is 1958 United States Grand Prix

Overview

The 1958 United States Grand Prix marked the final round of the 1958 Formula One World Championship. Held on November 30 at the Sebring International Raceway in Florida, it was only the second F1 race ever held in the United States and the first at Sebring, a venue better known for endurance sports car racing.

This race was pivotal in deciding the Drivers' Championship, with a close battle between Mike Hawthorn and Stirling Moss. Despite Moss winning the race, Hawthorn’s fourth-place finish was enough to secure him the title by a single point—the closest margin in F1 history at the time.

• November 30, 1958 was the official date of the race, making it the season finale of the 1958 F1 campaign.
• The Sebring International Raceway circuit measured 8.350 km (5.2 miles), combining paved track and temporary road sections.
• Stirling Moss claimed victory driving for Vanwall, completing the 40-lap race in 2 hours, 32 minutes, and 2 seconds.
• Mike Hawthorn, driving for Ferrari, finished fourth, which earned him just enough points to win the championship by one point over Moss.
• The race featured 20 starters, with only seven classified finishers due to mechanical failures and accidents on the bumpy circuit.

How It Works

The 1958 United States Grand Prix followed the standard Formula One regulations of the era, including a 2.5-liter engine limit and point-based championship scoring. The race format included practice sessions, qualifying, and a final 40-lap race, with points awarded to the top six finishers.

• Championship Scoring: Points were awarded 8-6-4-3-2-1 for the top six, with only the best four results counted from the eight races.
• Sebring Circuit Layout: The temporary circuit combined sections of the airfield runway and surrounding roads, creating a bumpy and challenging surface.

• Ferrari Dino 246 was Hawthorn’s car, featuring a 2.4L V6 engine and crucial reliability in the final race.
• Time Constraints: The race lasted over two and a half hours, testing both driver endurance and mechanical durability under Florida heat.
