The Gauntlet event for a the Aston Martin Vulcan has started.

This one is totally different, as the challenges are are randomized, and you need to win 300,000 pts over 8 days get the car.

So far I've done 3 challenges, first two were with the BMW Z4 Coupe a 1-lap cup at Mazda and an Autocross at Brands Hatch.  I think everyone is different.  The 3rd challenge of the set is a boss challenge where you get the race and upgrade the Vulcan.  

Looks like I can continue to run challenge 4 right away, not sure if there is a daily limit.

Update: #1
I'm onto challenge #7 now, looks like you only accumulate pts after you win a boss challenge.  #6 was a bit scary as I had a 2-lap cup at Melbourne with 0 upgrades on my car.  Will probably wait the 2hrs now for the 1st set of upgrades to complete, as I'm not sure what happens yet if you lose a challenge.

Looks like all the crazy stuff is here too, as I had one challenge where the steering was pulling left.  But not as bad as it was before.

I also think the cars for to use in the challenges are set, as one of the rewards increases the roster of cars to choose from.  So far, I only have the Z4 Coupe and 350Z to choose from.

Update #2:  Found a screen that shows the cars.
