The M139 engine seen in the A 43, C 43 and GLC 43 normally developed 450 BHP but in the C 63 S E Performance, it develops 476 BHP due to the larger turbocharger and better thermal management. This is built in Affalterbach, using the "One Man, One Machine" method.

Expensive at Rs. 1.95 crore. Typical CBU pricing
Brakes bite very late
Clinical compared to its peers and predecessor
Complexity means it depends on AMG support forever
