How are the European-spec and North American-spec M coupe interiors different?
The interior of all M coupes are essentially identical except for the instruments. In the main cluster, early Euro-spec cars have a 280 kph/170 mph speedometer and a tachometer that reflects the S50 engine’s 7,200-rpm redline, while North American models have a 160-mph/260 kph speedometer and a tachometer with a redline graduated between 6,500 and 7,000 rpm to reflect the S52 engine’s variable redline. In the center console, European models have an outside temperature gauge instead of the voltmeter used in North American editions. The later S54-powered M coupes all have essentially the same grey-faced instruments, including a 280 kph/170 mph speedometer and an outside temperature gauge (Fahrenheit on U.S. models, Celsius for all others). All M coupes sold in North America are equipped with cruise control and the Harmon/Kardon audio system, optional features in some other markets.
