You've driven faster than a Russian torpedo, which incidentally is 230 mph.

To get this achievement, you'll want to first progress to WSR Season 5, where you will introduced to Tier Four vehicles. During the season, you'll want to do the ESPN Endurance Promo Event, where you use the Koenigsegg Agera R. During the race, you will take a big hairpin turn after about 20-30 seconds, coming into a long straight. Just accelerate down the long straight until you get the achievement. You might need go full speed into a wall to get the extra few clicks on the speedometer.
