NASCAR The Game 2011

The quickest way to get this out of the way is to go into eliminator. You can select "By manufacturer." The four you need are:

Chevrolet
Ford
Dodge
Toyota.

You can set it to the shortest track (Martinsville) with the lowest amount of opponents (1) and the race will only take 25 seconds to win. rinse and repeat for each manufacturer.

While eliminator is indeed a quick way to get this cheevo, I feel the need to clarify things a bit.

Eliminator events can be found in career and single player. About half way through my first season, I had unlocked an eliminator event. It was Pocono and was found in the Invitational Events section of career mode. The AI were not that hard and I was able to gather quite a bit of NXP through overtaking and drafting while working my way through the field. I then stayed behind the first place car for even more NXP until I thought it was time to secure first place to win the event. I also got the "Tailgating" cheevo on one of the straights during this event. Since you can't change manufacturers during career mode, it's now time to go to single player mode for the remaining three manufacturers.

Start from the main menu screen and select Single Player. From there you will find a screen with , among other things, the three remaining manufacturers. Pick one of the remaining ones needed and then select a driver. You should now have a screen to select the Eliminator Event. You can now select a track. I chose Dover as it's my "home" track. You now have a screen to select opponent difficulty and number of opponents. No brainer on difficulty unless you're a glutton for punishment. I chose 42 opponents to gather up as much NXP as possible during these events as well. This helps to contribute to the "ranking up" cheevos. When you win a 43 car eliminator event you will also get the "Last Man Standing" cheevo. ;-)

I hope this helps.
