2010 BMW 535i GT

The 2010 BMW 535i GT (Gran Turismo) is a unique vehicle blending sedan, wagon, and SUV characteristics. The 535i GT was available with either a 3.0L Turbo Inline-6 (N54) or a 4.4L Twin Turbo V8 (N63). For the 2010 model year, both engines were paired with a 6-speed automatic transmission. The 3.0L Turbo Inline-6 produced 300 horsepower and 300 lb-ft of torque. Owners generally appreciate the 535i GT for its spacious interior, comfortable ride, and luxurious features. Common complaints include the complex iDrive system, the divisive styling, and the potential for expensive repairs due to the vehicle’s advanced technology and BMW’s generally high maintenance costs.
