Specs side by side
What owners say
4 Series
Overall
Sentiment is mixed and heavily dependent on the specific model, engine, and generation. For the F-generation (e.g., 428i, 430i, 435i, 440i), owner feedback is generally positive regarding driving dynamics, styling, and the overall package of technology and comfort. These cars are frequently described as "amazing," "solid," and "great all-rounders" that offer a satisfying blend of performance and luxury features.
Best version to buy
Models equipped with the B58 inline-six turbocharged engine (e.g., 435i, 440i, M440i) receive the most consistent praise for performance, smoothness, and being a "great drivetrain." The M440i with its mild-hybrid system is specifically noted for its refined start-stop and improved low-end response. For the F-generation, the 435i is frequently mentioned as a desirable and reliable powertrain choice.
Known issues
- High cost of ownership and unexpected repairs: budgeting $1,000-$3,000+ annually for maintenance and repairs is frequently mentioned, with major services (e.g., timing chain) potentially costing $4,000-$5,000. Frequency: very frequent.
- N55/B58 engine oil filter housing cracking: a well-known issue on certain engines, particularly noted on the N55. Frequency: recurrent.
- Timing chain rattle on cold start (4-cylinder engines): specifically mentioned for the 2.0L petrol engines, a sign of potential wear. Frequency: recurrent.
RC
Overall
Mixed to positive sentiment, heavily dependent on model variant and owner expectations. The RC F (V8) is consistently praised for its bulletproof reliability, exceptional build quality, comfortable and luxurious cabin, and the character of its naturally aspirated V8 engine. It is widely regarded as a superb grand tourer and daily driver that excels in comfort and long-term ownership confidence.
Best version to buy
RC F with the Torque Vectoring Differential (TVD). This configuration is specifically highlighted for improving handling dynamics over non-TVD models.
Known issues
- Underwhelming 8-speed automatic transmission (RC F): described as decent but not snappy or engaging, with laggy response in normal mode, slow shifts when cold. Not a dual-clutch. Frequency: very frequent.
- Substantial weight negatively impacts handling: car feels heavy, not as agile or communicative as competitors, limits spirited canyon/track driving. Frequency: very frequent.
- Firm ride quality (Non-F, especially F Sport): ride is noticeably firmer and less comfortable than a contemporary IS 350, described as less "cloud-like". Frequency: recurrent.
