Overview

2020 BMW M8

The 2020 BMW M8 is a formidable grand tourer, blending aggressive performance with luxury appointments. Under the hood, its twin-turbocharged 4.4-liter V8 engine delivers between 600 and 617 horsepower, paired with an 8-speed automatic transmission and all-wheel drive. While its EPA combined fuel economy is 17 MPG, owners should be aware of its premium fuel requirement. This M8 presents a compelling, albeit high-stakes, used performance car option.

Critical Failure Risk

A critical recall addressed potential issues with the integrated brake system due to improper welding of the rotor and shaft. This could lead to separation during hard braking, causing a loss of ABS and braking assistance. While addressed by recall, owners should remain vigilant.

Early detection can help you avoid a $1,500-$3,000 repair.
