After the first two months of 2019 have been largely dominated by pre-season testing events, the racing season starts in earnest in March.

F1, MotoGP and IndyCar all begin racing this month, while WEC returns to action for the first time after its winter break, as the action ramps up to provide some busy weekends of racing.

Here is a comprehensive guide to this month’s top motorsport to watch out for.

Qatar MotoGP (March 8-10)

With testing wrapping up at the end of February at the Losail International Circuit, all that remains left is to get racing underway with MotoGP starting in Qatar for the opening round.

Andre Dovizioso held off Marc Marquez to win the opening round at the same track 12 months ago, while the Ducati riders have impressed during winter testing, but the true pecking order will become clear at the opening race under the floodlights as the first grand prix race of the year takes place at night in the Qatari desert.

Formula E: Hong Kong ePrix (March 10)

Formula E heads East once again in the 2018-19 season with a return to Hong Kong on March 10. The all-electric series last visited back in 2017, when Hong Kong hosted the 2017-18 season opener with a double-header, and will welcome the championship back for round four of the current campaign.

All four of the opening rounds have been won by four different drivers from four different teams, helping create the unpredictable nature of the first season of the Gen2 cars, while the three previous Hong Kong ePrix have also all been won by different drivers.

Formula E stays in Asia for an all-new race in China, the Sanya ePrix, two weeks later on March 23 before starting its European leg in April.

St Petersburg, IndyCar (March 10)

A highly-anticipated 2019 NTT IndyCar Series gets underway this month, starting in familiar surroundings in Florida with the Firestone Grand Prix of St. Petersburg (March 10) before an all-new trip to Circuits of the Americas in Texas for the IndyCar Classic two weeks later.

Sebastien Bourdais enjoyed the perfect start to his 2018 IndyCar campaign at St. Petersburg, taking a second consecutive win in Florida, but with 2019 kicking off a new era of the America single-seater series the new season looks wide open.

The first-ever IndyCar Classic at COTA takes place on March 24.

F1 Australian Grand Prix March 15-17

The 2019 Formula 1 World Championship begins at its traditional starting point down under at Albert Park in Australia. New faces, new teams (sort of) and tweaked technical rules throws up plenty of uncertainties for this season, with Liberty Media’s attempt to improve racing set to face its biggest test at the tight and tricky Melbourne street circuit.

Ferrari showed impressive pace during pre-season testing with reigning F1 world champions Mercedes trailing but with Sebastian Vettel winning the past two Australian Grand Prix it has proven a red herring for where the big prizes would end up.

Two weeks later F1 hosts its 999th race, the Bahrain Grand Prix, on the final day of the month as the sport races at night for the first time this year.

1000 Miles of Sebring World Endurance Championship/IMSA 12 Hours of Sebring (March 15-16)

Sebring International Raceway hosts a historic double-header of action this month as the World Endurance Championship and IMSA unite at the Florida circuit.

WEC ends its winter break of the 2018-19 Super Season with the 1000 Miles of Sebring on March 15, which will be cut-off if it reaches eight hours of racing, as Toyota Gazoo Racing looks to tighten its grip on the world title.

One day later the 12 Hours of Sebring takes place to host the second round of the 2019 IMSA championship following on from the dramatic opening round, Daytona 24 Hours, in January.
