You know a video game is awesome when it deems itself as still subject to further improvements even after it's already being played in households all over the world.

That's what we think of Gran Turismo 6 because, for all the incredible and realistic gameplay it offers, Polyphony Digital still cranks out updates and downloadable contents like the game depends on it. Even more impressive is the fact that developers can do it barely two weeks after the game hit shelves.

You know where we're going here. Gran Turismo 6 has a new content gamers can download, and like most of what it's produced for its predecessors, this one comes with a whole load of new cars and new features, including in-game mentoring coming from four-time Formula One->ke190 world champion Sebastian Vettel->ke3801.

As for the cars, there's a list that runs the gamut of Red Bull race cars, ranging from a racing kart all the way to the Red Bull X2014 Junior race car.

There's a lot to like about this new content but the best thing about it is that it's free, which means you won't have to spend an iota to acquire it.

That's about as good a holiday present as you can get from GT6 at this stage of the game.

2013 Red Bull X2014

As a partner of the Gran Turismo franchise since the fifth installment of the game, Red Bull is always looking to find ways to have its race cars in the game. So when Gran Turismo announced that a slew of exclusive concepts were being prepared for the game.

That's what Red Bull is doing with the creation of the X2014. It comes in three different versions, including the Red Bull X2014 Fan (X2014/F), the Red Bull X2014 Standard (X2014/S) and the Red Bull X2014 Junior (X2014/J).

So, we’re not talking about just one car, but three different concepts imagined for the racing world. That's three times the fun!

All three concepts were designed by Polyphony Digital Inc. in collaboration with Adrian Newey, Chief Technical Officer of four-time F1 champions, Red Bull Racing and just like the other concepts that are a part of the Vision Gran Turismo program, the new X2014 will be offered exclusively int he GT6, so if you want to drive it, you’ll have to buy the game.
