The 4 Series coupe, convertible, and four-door Gran Coupe hatchback--based on the 3 Series sedans--pack in healthy doses of style, luxury, and exclusivity. Lower and wider than the 3 Series, the plush and comfortable 4 Series is meant as a touring car rather than a pure sportster. Yet they are quite capable. Handling is taut, the ride is steady and compliant, and the interior is plush.

Owner Reports

Worse Better
Reliability History Reliability History The reliability charts are based on responses on hundreds of thousands of vehicles from our latest Annual Auto Survey. Consumer Reports subscribers reported on any serious problems they had with their vehicles during the past 12 months that they considered serious because of cost, failure, safety, or downtime, in any of the trouble spots included in the table below. The results are presented relative to the average model that year. Extra weight is given to the more serious areas such as major engine or transmission problems. Based on this data and further analysis, we predict reliability for the latest year. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Owner Satisfaction Owner Satisfaction To learn about satisfaction, CR has collected survey data from our annual survey on more than half a million vehicles. Our subscribers provide great insights into their satisfaction by answering one simple question: If they had it to do all over again, would they definitely buy or lease the same model? In addition, respondents also rate their cars in six categories: driving experience, comfort, value, styling, audio, and climate systems. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Model Summary
The 4 Series coupe, convertible, and four-door Gran Coupe hatchback--based on the 3 Series sedans--pack in healthy doses of style, luxury, and exclusivity. Lower and wider than the 3 Series, the plush and comfortable 4 Series is meant as a touring car rather than a pure sportster. Yet they are quite capable. Handling is taut, the ride is steady and compliant, and the interior is plush. The turbocharged 2.0-liter four-cylinder is sparing with fuel; the 3.0-liter six-cylinder turbo is supersmooth and delivers effortless go. All-wheel drive is optional. The ultra-high-performance M4 is a track-ready version. First-year reliability has been above average.
