GRID Legends

I chose Achevée as my sponsor. The event is located under Grid Challenges in Semi-Pro.

You need to complete the following objectives:
425 Damage against Voltz.
Top 3 with 50% health.
136km driven in Demolition Derby cars.

The Voltz drivers are Lauri Dixon and Prince Venter. I chose Achevée sponsor before starting the story mode and got 90 damage and a few km driven at the end.

For the remaining damage I created a quick race in the Demolition Derby class with the Belta Frostbite car and 4 drivers. 2 drivers will only spawn your teammate. 4 drivers will give you the 2 Voltz drivers as enemies. Ram them while grinding for the 136km.

Once you get the 425 damage you can go back to 2 drivers and work on this achievement:

**Updated with info from: neil3646
Once you complete the 3 objectives for one of the 3 new sponsors, it should unlock a new career event within the Semi-Pro section (I think), under Grid Challenges

Complete one of these 3 new events and the achievement should unlock

You don’t get the achievement for fulfilling the sponsor objectives, rather for doing the new event that unlocks within the career mode section

**The new sponser objectives are as follows:

ACHEVEE:
Damage dealt to Volts
Top 3 finishes with 50% Health remaining
Km driven in Demolition vehicles

LUGNA:
Damage Dealt to Seneca
Air Overtakes
Laps completed in Demolition Derby
