111 Meters a Second

111 Meters a Second is a bronze-level PSN trophy from Gran Turismo 5. It is acquired upon travelling at 400km/h (111.1 ms-1, 250 mph) for the first time.

Walkthrough
Several cars are capable of travelling above 250mph (with some modifications), including:
 * Red Bull X2010 '10
 * Red Bull X2011 Prototype '11
 * Bugatti Veyron 16.4 '09
 * Formula Gran Turismo
 * Suzuki ESCUDO Dirt Trial Car '98

The two Red Bull cars can reach 250mph on almost any circuit. For other cars, a circuit with long straights is required to do so.

Among the best circuits on which to achieve this are:
 * Special Stage Route X
 * Special Stage Route 7
 * Daytona Superspeedway
 * Indianapolis Superspeedway
