The BMW X3 M Competition is a fantastic performance SUV that boasts a practical, luxurious interior combined with a potent twin-turbocharged 6-cylinder engine rated at over 500 horsepower. This particular X3 M features some great equipment like the Executive and Driving Assistance Pro packages, ventilated front seats, and a Harman Kardon surround sound system – and it's finished in an attractive Brooklyn Grey Metallic over Tartufo color combination. Power comes from a 3.0-liter S58 twin-turbocharged inline-6, which produces 503 horsepower and 479 lb-ft of torque. Output is sent to all four wheels via an 8-speed M Sport automatic transmission and BMW's xDrive all-wheel drive system.
