When it goes on sale this month, the F80 2015 BMW M3 Sedan will cost $62,000 and 2015 BMW M4 sells for $64,200. Destination and handling is $925.
BMW has reverted to an inline six cylinder for the new M3 and M4. But unlike the S54 in the E46 M3, the new S55 is turbocharged. Based on the N55 six cylinder, the S55 utilizes VANOS and Valvetronic as well as gasoline direct injection in the cylinder heads.
Unlike the N55′s twin-scroll single turbocharger, the S55 utilizes two turbochargers, one turbo per three cylinders.
The S55 is set to deliver 425 HP and 406 lb-ft of torque. The torque developed by the S55 is fully available from 1,850 to 5,500 RPM.
