Welcome to the Jalopnik , where we let you know what's going on in the world of racing, where you can see it, and where you can talk about it all in one convenient place. Where else would you want to spend your weekend?

This is a big weekend with a little bit of everything: IndyCar, Pirelli World Challenge, NASCAR, F1, NHRA, MotoGP, AMA Supercross, and shoot, I'm even attempting not to crash a boyfriend's car at a time-speed-distance rally. There's magical frozen water in white clumps everywhere here. I'm from Texas. WE DON'T GET THAT. (Help!)

Last week's Formula One race was like watching Formula Ultra-Wacky Knockout . Look, a higher percentage of cars make it to the end of a 24 Hours of LeMons race than to the end of the 2015 Australian Grand Prix. Is this week going to be any better? Well, for one, we've at least got a delightfully clean and largely sponsorless pair of Manor Marussia cars now turning laps in practice, so whoohoo! Maybe those 2014 cars, y'know, work?

The Formula One Australian Grand Prix itself was a bit of a turd, with more excitement over which…

Place your bets now for when (not if, but when) the Red Bull Renaults 'splode. I'm so glad my background is in LeMons racing. I feel like I understand Formula One's reliability plight so much better as a result. There are lemons. Turds. Rolling poopbaskets. This is the so-called pinnacle of motorsport? Okay. I'm pretty sure I could take on at least one McLaren in a Volkswagen Type 3, though. I'm just sayin'. It's bad. Really bad. Please get better soon, F1. Deliver sweet racing action like you should. Otherwise, this feels like a must-watch for all the wrong reasons.

F1, of course, isn't the only show on TV. We finally get IndyCar's season opener! Will the Honda IndyCars catch up with the Chevrolets in the race? It seems like Chevy's whole car package nailed it out of the bag, and now Honda's being forced to play catch-up. The fastest Honda in practice came in sixth, though, so thankfully, they're not too far off the pace. C'mon, Honda. Give us the cross-manufacturer battles we all deserve.

And oh, there's some crazy stuff going on with NASCAR tires, apparently. The rumor is that some teams have devised a system (read: drilled some holes) that allow tires to maintain a certain pressure instead of ballooning up when they get too hot. Who's cheating and how there? And why on earth are they doing that with something that's considered a safety item by nearly every racing series on the planet? Tampering with safety items is generally considered a bad idea, guys. Must we whip out the lecture about inadequately-tubed roll cages and unsafe fueling mods again?
