Detroit, Michigan – BMW has unveiled two new members of the 5 Series lineup, the ActiveHybrid 5 and M5, at the North American International Auto Show in Detroit.
The ActiveHybrid 5 uses a 3.0- litre turbocharged inline six-cylinder engine, electric drive system and eight-speed automatic transmission, providing a combined 340 horsepower with the ability to run on battery power alone at speeds of up to 60 km/h. The new hybrid accelerates from zero to 100 km/h in 5.9 seconds, but delivers fuel economy of between 6.4 and 7.0 L/100 km. A lithium-ion battery pack is integrated into the trunk.
The fifth-generation M5 uses a newly-developed 4.4-litre twin-turbocharged V8, the most powerful engine used in a production M vehicle, producing 560 horsepower and 502 lb-ft of torque. A seven-speed M Double Clutch transmission also includes start/stop technology for improved fuel efficiency.
Features include electronically-controlled dampers, M-specific Servotronic steering, M Dynamic mode stability control and high-performance compound brakes, along with sport seats, M steering wheel and instrument cluster, and for the first time, two M Drive buttons for driver control of engine and suspension settings.
