NEW TRACK
Hampshire, England
Hampshire, England’s Thruxton Circuit traces its history back to 1950, when the former RAF Thruxton airfield—home base for many key Allied efforts during World War II—first saw use in motorcycle races. The main circuit was established in 1968, following the outline of the airfield’s perimeter road. It currently hosts major British touring car and superbike events each summer, as well as series like the F4 British Championship and TCR UK.
Befitting a circuit built around active runways, Thruxton is known as “The Fastest Circuit in the UK.” A lap of Thruxton features just 12 turns in its 3.793 km (2.356 mile) layout, and few of them are particularly sharp. While its race lap record is still over a minute, owing to the levels of racing it typically hosts, there’s potential for a much faster time in higher-class equipment with its gradual curves. Damon Hill turned a lap of 57.6 seconds with an average speed of over 147 miles per hour in his Williams FW15C in 1993 that serves as the unofficial track record.
NEW TRACK
Brandon, South Dakota, USA
Named after farmer and businessman Til Huset, Huset’s Speedway was built in 1953 and opened the next year. As with so many of America’s premier dirt ovals, the track was built out of former farmland—in this case, a soybean field—and has hosted many of the top national series in the country, including the World of Outlaws Sprint Car Series. After a brief stint as the Badlands Motor Speedway in the mid-2010s and subsequent closure, the track was rescued in the summer of 2020 by Tod Quiring, who returned top-level sprint car racing to the South Dakota circuit quickly thereafter.
Huset’s Speedway measures in as a high-banked, 1/3 mile bullring. It typically hosts both weekly and national level racing through Labor Day weekend. The Huset’s High Bank Nationals and Huset’s Hustle for sprint cars each offer six-figure payouts to their winners, while the Silver Dollar Nationals pay $75,000 to win for top late model racers. Adding to the track’s prestige, Quiring also prominently displays the Huset’s brand on his Big Game Motorsports 410 Sprint Car on the World of Outlaws national tour, where he and driver David Gravel have teamed up for dozens of checkered flags in recent seasons.
Our latest tire model evolution, debuting on the GTP and LMP2 classes, features improved dynamic response and a new degradation mechanism. In addition, more realistic compounds and constructions produce more appropriate responses and grip levels.
The lighting for the entire iRacing world has undergone an improvement which increases contrast and reduces some excessive brightness.
AI drivers will now flash their headlights as they approach behind you when they prepare to overtake.
Your spotter will now inform you if any damage you receive is going to have a negative impact on an aspect of your vehicle performance.
