The 2011 BMW 335is is a performance-oriented variant of the 3 Series that combines luxury with a sporty edge. As an auto owner, you want to know if this car can hold up to daily driving demands without constant trips to the mechanic. The 335is is equipped with a robust engine and a well-engineered transmission, but like any vehicle, it has its strengths and weaknesses.
Engine Performance
The heart of the 335is is its turbocharged inline-six engine, which delivers impressive power and torque. With 320 horsepower on tap, this engine is known for its responsiveness and smooth delivery. However, potential buyers should be aware of a few common issues. Some owners have reported problems with the high-pressure fuel pump and fuel injectors. Regular maintenance and using high-quality fuel can mitigate these issues, but it’s something to keep in mind.
Transmission Reliability
The 335is comes with either a six-speed manual or a seven-speed dual-clutch automatic transmission. Both options are generally reliable, but the dual-clutch system can be a bit finicky if not properly maintained. Owners have noted that the transmission fluid should be changed at regular intervals to ensure longevity. If you’re considering a used model, check for any signs of rough shifting or delayed engagement, as these could indicate underlying problems.
Suspension and Handling
When it comes to suspension, the 335is features a sport-tuned setup that enhances its handling capabilities. The ride is firm but not overly harsh, striking a balance that many drivers appreciate. However, the sport suspension can lead to premature wear on components like bushings and struts, especially if the car has been driven aggressively. Regular inspections can help catch any issues before they become costly repairs.
Other Key Components
In terms of electrical systems, the 335is has been known to have some quirks. Issues with the battery and alternator can arise, particularly in older models. It’s wise to keep an eye on the battery’s health and replace it if you notice any signs of weakness. Additionally, the cooling system is crucial for maintaining engine performance, so be sure to check for leaks or signs of wear in hoses and the water pump.
Final Thoughts
Overall, the 335is is a solid choice for those who want a blend of performance and luxury. While it does have its reliability concerns, many of these can be managed with proper maintenance and care. If you’re willing to stay on top of regular service, this car can provide a thrilling driving experience without too many headaches.
