If you’re shopping for a used or certified pre-owned BMW, chances are you’ve come across the 330i and 335i—two of the most talked-about models in the 3 Series lineup. They may look similar on the surface, but underneath, they cater to different types of drivers. Whether you’re after efficiency, tuning potential, or pure performance, understanding the key differences between the 330i and 335i is essential. Let’s break it all down so you can make the right choice.
BMW 330i vs 335i: Quick Overview

|---|---|---|
| Production Years | 2001–2006 (E46), 2017–Present (G20/F30) | 2007–2015 (E90, E92, F30) |
| Engine | 2.0L Turbocharged I4 (B48/N20) | 3.0L Turbocharged I6 (N54/N55) |
| Horsepower | 248–255 hp | 300 hp (stock) |

Performance Comparison
The 335i is the clear performance winner between the two, thanks to its inline-6 engine. Whether equipped with the N54 or N55, it delivers a smoother, more powerful driving experience. It’s especially popular among enthusiasts due to its tuning potential. The N54 in particular—used in earlier models—is known for handling 400+ hp with simple bolt-ons.
The 330i, however, should not be underestimated. With BMW’s newer B48 or N20 engines, it offers great low-end torque, a quick-shifting 8-speed automatic, and excellent efficiency. While not as explosive as the 335i, it provides more than enough power for everyday driving and sporty weekend runs.
Engine Highlights
- 330i (G20): B48 2.0L I4 turbo – more efficient, lighter, and lower emissions
- 335i (E90/E92): N54 twin-turbo or N55 single-turbo I6 – more raw power, better tuning
Driving Dynamics
Both cars are built on the same chassis platforms for their respective generations, so you’ll find a familiar balance and BMW’s signature steering feel. The 335i offers a more thrilling experience, especially in rear-wheel-drive form. The 330i feels more refined and lighter up front, with slightly better weight distribution due to the smaller engine.
If you’re after sharper cornering and everyday comfort, the 330i has the edge. For straight-line speed and engine sound, the 335i wins.
Reliability and Maintenance
This is where the 330i shines—especially newer models with the B48 engine. It’s more fuel-efficient, easier to maintain, and generally more reliable over 100,000+ miles. The 335i, particularly those with the N54 engine, is notorious for several common issues:
Common 335i Problems
- High-pressure fuel pump (HPFP) failure
- Turbo wastegate rattle
- Carbon buildup on intake valves
- Water pump and thermostat failures
Common 330i Issues
- Timing chain concerns on N20 engines (2012–2015 models)
- Oil leaks from valve cover and filter housing
- Occasional turbo actuator issues
Tip: If long-term reliability with fewer headaches is your top priority, the 330i is the better bet. If you’re okay with more maintenance for higher performance, the 335i can be very rewarding.
Interior and Technology
Later 330i models (F30/G20) offer significantly more modern tech compared to most 335i variants. You’ll find larger infotainment screens, digital driver displays, improved iDrive systems, and more driver-assist features in the 330i. Earlier 335i models lack Apple CarPlay, advanced navigation, or voice assistants unless retrofitted.
330i Interior Features (G20):
- Digital instrument cluster
- Touchscreen with iDrive 7
- Apple CarPlay and Android Auto
- Standard driver assist tech
335i Interior Features (E90/F30):
- Smaller infotainment displays (depending on year)
- iDrive 4 or 6, depending on model year
- More analog controls and classic BMW feel
Which One Should You Buy?
Buy the 330i if you want:
- Better fuel economy
- Newer tech and driver-assist features
- Lower cost of ownership and fewer long-term repairs
- Smooth power delivery with solid performance
Buy the 335i if you want:
- Raw performance and tuning potential
- Smooth, refined inline-six engine feel
- Classic BMW driving dynamics and sound
- A better foundation for a performance build
Final Verdict
The BMW 335i is the enthusiast’s pick, while the 330i is the smart daily driver. The 335i delivers old-school BMW thrills, especially if you’re willing to invest in maintenance and upgrades. On the flip side, the 330i is more modern, efficient, and hassle-free—ideal for someone who wants sporty luxury without the extra effort.
Tip: If you’re buying used, always get a pre-purchase inspection—especially on the 335i. Ask for records on the HPFP, water pump, and valve cover gaskets. For the 330i, confirm timing chain updates if it’s a 2012–2015 model.
