What is the AMG C 43 • The C 43 is a performance-tuned version of the compact sedan/sports-sedan from Mercedes‑Benz, built under the tuning and performance sub-brand Mercedes‑AMG.  • It sits above the “regular” C-Class but below the top-end (insane horsepower) AMG models, delivering a balance between everyday usability and sporty performance.  🔧 Engine & Performance • Newer C 43 sedans use a hand-crafted 2.0 L inline-4 turbocharged engine (with mild hybrid assist / electric turbo assistance)
