In the wake of Formula One's near collapse and the shock resignation of Indy chief Tony George, it'd be all to easy to assume these are the only two racing series in serious trouble. However, emerging reports indicate that they're only the tip of the proverbial iceberg.

According to the latest, both the Speedcar and A1GP series are on the verge of total collapse. The former, for those unacquainted, is a stock car series pitting former F1 drivers like Jean Alesi, Heinz-Harald Frentzen and Jacques Villeneuve against each other on tracks around the Middle and Far East. After only two short seasons of operation, Speedcar's official website is offline and reports suggest the cars have been parked along with it.

Meanwhile, the A1GP World Cup of Motorsport, an open-wheel feeder championship between various national teams, appears to be going down the same path. Only one season after unveiling their new Ferrari-designed and -powered spec single-seaters, A1 Grand Prix Operations Ltd has reportedly declared bankruptcy and began liquidating its assets. A1 was starting to position itself as an alternative to the likes of GP2 and the new Formula 2 as a feeder series for aspiring F1 drivers, but its purported collapse will leave that territory to the mainstream series, while Speedcar's demise will leave one less sunset into which burnt-out grand prix pilots can ride off.
