European Le Mans - Goodyear 4 Hours of Silverstone

The Goodyear 4 Hours of Silverstone returns to the European Le Mans Series calendar. This endurance race brings prototype and GT cars to Silverstone Circuit in Northamptonshire, UK. The event features four categories of racing machines competing over a four-hour distance. The Automobile Club de l'Ouest (ACO) organizes this race, the same body that runs the 24 Hours of Le Mans. The weekend includes support races from the Michelin Le Mans Cup, Ligier European Series, and Eurocup-3 single-seater championship.

Race Format and Weekend Structure

The Goodyear 4 Hours of Silverstone tests driver skill, team strategy, and car reliability. Teams must manage fuel consumption, tire wear, and driver changes across the four-hour duration. Each driver in a car must complete at least 40 minutes of the race. The weekend begins with two 90-minute Free Practice sessions and a 30-minute Bronze Test session. Qualifying consists of a 15-minute session for each category.

The qualifying format varies by class. Any driver can qualify LMP2 and LMP3 cars. However, only Bronze-rated drivers can qualify cars in the LMP2 Pro/Am and LMGT3 categories. This rule adds a strategic element to these classes. Race officials can deploy Full Course Yellow, Virtual Safety Car, or Safety Car procedures for safety reasons.

Silverstone Circuit

Silverstone Circuit hosts the race at a venue with significant motorsport heritage. The circuit began as a World War II airfield and held its first race in 1948. It hosted the inaugural Formula One World Championship Grand Prix in 1950. The modern configuration measures 5.891 kilometers (3.661 miles) and features 18 turns. The layout includes seven left-hand corners and eleven right-hand turns.

The circuit combines fast corners like Copse with the technical Maggots-Becketts complex. This combination challenges drivers across all categories. The flowing nature of Silverstone suits endurance racing, where drivers must find rhythm while managing traffic from multiple classes. The track surface and corner speeds demand precise car setup and tire management.

Categories and Participants

The ELMS grid at Silverstone includes 47 cars across four categories. Each class has distinct characteristics and driver rating requirements.

LMP2 (Le Mans Prototype 2)

The premier prototype class features 11 entries. These teams run carbon monocoque chassis from Dallara, Ligier Automotive, Oreca, or Riley Tech/Multimatic. All LMP2 cars use the Gibson GK428 4-litre V8 engine, which produces approximately 600 horsepower. Cosworth Electronics supplies the control electronics package. Driver lineups must include at least one Silver-rated driver. Confirmed entries include Forestier Racing by Panis and Inter Europol Competition with Jakub Smiechowski, Tom Dillmann, and Nick Yelloly.

LMP2 Pro/Am
