The new 2021 BMW M3 and M4 include water and oil cooling systems designed to stand up to the high temperatures of track use. Large front intakes ensure that there is a sufficient flow of air to the low-temperature and high-temperature radiators in the upper part of the grille opening. The lower area air flow is used to support the engine oil cooler, and in Competition models, a separate transmission oil cooler.
The low temperature cooling circuit features an electric cooling pump which supplies flow for the intercooler. The high temperature circuit supplies coolant to the engine and turbochargers through a mechanical coolant pump, main radiator and two supporting radiators in the front wheel wells. An additional electric cooling pump allows for turbocharging cooling to continue even after the engine has been switched off.
Decades of BMW M GmbH’s racing experience shows in the oil system where the oil sump features two chambers and a map-controlled oil pump. When extra, controlled lubrication is needed, such as during high longitudinal or lateral loads, oil is pulled from the smaller sump chamber to ensure proper supply.
Powered by the latest version of the 3.0-liter, inline-cylinder, BMW TwinPower Turbo S58 motors producing up to 503 hp, the new M3 Sedan and M4 Coupe also offer the choice of traditional 6-speed manual transmission, something that is rare in the cars’ segment.
MSRP pricing is $69,900 for the M3 Sedan, $72,800 for the M3 Competition Sedan, $71,800 for the M4 Coupe and $74,700 for the M4 Competition Coupe. $995 Destination is in addition to all MSRP pricing.
