GT4
The Mercedes-AMG GT4 features twin-turbocharged 4.0-liter V8 producing 510-544 horsepower depending on specification and Balance of Performance regulations through six-speed sequential transmission operated pneumatically and rear-wheel-drive in transaxle configuration at 1,390kg (3,064 pounds) curb weight reduced approximately 300kg from road-going GT R through extensive carbon fiber construction. GT4 specification includes motorsport neural network enabling power adjustment from 400-544 horsepower meeting various championship requirements, racing ABS with multiple adjustment settings, mechanical limited-slip differential, adjustable suspension geometry, competition brake package, integrated roll cage with FIA compliance, racing seat with six-point harness, and aerodynamic package optimized for GT4 homologation balancing downforce generation with drag reduction.
AMG GT4 represents Mercedes-AMG Customer Racing entry into GT4 category based on production AMG GT sports car platform, establishing competitive presence across global championships including SRO GT4 European Series, British GT, and IMSA Michelin Pilot Challenge through combination of powerful twin-turbo V8 architecture and sophisticated electronics management. The 25,000 racing miles recommended rebuild interval demonstrates durability engineering supporting cost-effective customer racing operations, while transaxle configuration optimizes weight distribution and allows precise handling balance adjustment through setup changes, with optional power increase to 544 horsepower positioning AMG GT4 among most powerful entries in category though Balance of Performance regulation typically limits output to maintain competitive parity, creating accessible platform combining German engineering precision with factory technical support infrastructure establishing Mercedes motorsport credibility in customer racing segment.
