Lot's of newcomersWe’re approaching the halfway mark of the IMSA iRacing Pro Invitational Series next week, with the third of six rounds taking place at the virtual Mid-Ohio Sports Car Course on Thursday, April 30, at 6 p.m. ET. The track is a fitting location, as several IMSA racing series would have been onsite next weekend in Lexington, Ohio in real life for the Acura Sports Car Challenge. While racing activities next weekend have turned virtual, the actual event is rescheduled to take place on September 25-27. In a Lotus at EstorilIt was 35 years ago, in monsoon conditions, that a determined young Brazilian raced to his first Formula 1 victory and cemented his name in motorsport folklore. It was Sunday 21 April and the 1985 Portuguese Grand Prix. Behind the wheel of a Lotus 97T was Ayrton Senna, just turned 25 years old. With the car at the absolute limit of its grip, he delivered a masterclass in wet-weather driving for the hardy Estoril crowd and powered to the checkered flag. Such was his dominance he lapped the entire field up to second place, finishing over a minute ahead of his nearest competitor.

Austria and Silverstone to open F1 season with 'ghost' racesAustria and Silverstone appear to be headlining F1's return to racing action. It is believed a new race calendar will be published as soon as May, with the first two or three races to be held at the Red Bull Ring, followed by Silverstone. 'We have been asked if we could hold a race or two and could they be behind closed doors,' Silverstone boss Stuart Pringle told the Guardian. 'The answer is absolutely, we are open to looking into anything and everything.'
