Under the hood of the new 2018 BMW M5 is the newest version of BMW’s 4.4 liter twin-turbocharged V8 engine. Now, it makes 600 hp on the nose and 553 lb-ft of torque. All of that fury is sent through an eight-speed ZF-sourced automatic that’s been specifically tuned for M5 duty. To match the new tech in the M5, BMW has paired the engine with an M-engineered exhaust system, available in standard form, and also an M Sport Exhaust system available at an extra cost and initially incorporated into the special edition BMW M5 “First Edition”.
M Sport Exhaust
The cross-bank exhaust manifolds for the all-new BMW M5 have also been modified to optimize the flow of energy from the exhaust gas to the turbine wheels of the two twin-scroll turbochargers ensuring the best possible gas-exchange cycle. By fitting a Helmholtz resonator between the two silencers of the dual exhaust system, the M engineers have reduced its weight by 11 lbs.
Standard M Exhaust
The sound from the active flap-controlled exhaust system varies depending on the selected mode for the engine characteristics, while the M Sound Control button allows further acoustic customization.
In the M5 “First Edition”, the sports exhaust comes in high-gloss black. BMW has yet to release the full details on the M Sport Exhaust, but instead, they gave us a few short clips to see the difference.
