BMW 335i vs 535i vs 340i – Which is the Better Buy?

For many BMW enthusiasts, choosing between a used 335i, 535i and 340i is far from straightforward. At first glance, the larger and more expensive 535i would appear to be the obvious winner. However, the reality is far more interesting.

Let's take a closer look.

BMW 335i vs 535i – Same Engine, Different Philosophy

One of the biggest surprises is that the BMW 335i (F30) and BMW 535i (F10) share exactly the same engine.

Both are powered by BMW's excellent 3.0-litre N55 TwinPower Turbo inline-six producing:

• 306 hp

• 400 Nm of torque

So why is the 335i actually quicker?

The answer is simple: weight.

The 335i weighs around 150 to 200 kg less than the larger 535i. With identical power, the lighter car naturally accelerates faster, brakes better and feels more agile through corners.

The 535i, on the other hand, is designed with a different purpose. It offers a quieter cabin, a smoother ride, more interior space and outstanding high-speed comfort. It is a luxury sports saloon rather than an outright sports sedan.

Enter the BMW 340i

In 2015 BMW introduced the 340i, replacing the legendary 335i.

Although it still uses a 3.0-litre turbocharged inline-six, the engine changed from the N55 to the all-new B58.

Power increased to 326 hp while torque rose to 450 Nm.

On paper these numbers don't appear dramatically different, but behind the wheel the improvement is immediately noticeable. The B58 delivers stronger acceleration, more torque throughout the rev range, quicker throttle response and improved fuel efficiency.

Many enthusiasts regard the B58 as one of the finest six-cylinder turbocharged engines BMW has ever produced.

Reliability

The N55 has earned a solid reputation and is generally considered one of BMW's most reliable turbocharged petrol engines when serviced correctly.

Typical maintenance items include:

• Electric water pump

• Valve cover

• Oil filter housing gasket

• Ignition coils

• Charge pipe

The newer B58 improved upon many of these areas with:

• Stronger closed-deck engine block

• Improved cooling system

• Better timing chain design

• More robust fuel system

As a result, the B58 is often regarded as one of BMW's most durable modern engines.

Which BMW Gives the Best Value?

This is where many buyers are surprised.

Despite costing considerably more when new, today's used market often prices the 535i below the equivalent 335i.

Why?

The answer lies in demand.

The 335i has developed something of a cult following among enthusiasts who appreciate its lighter weight and huge tuning potential. Consequently, prices remain relatively strong.

The 535i attracts fewer buyers because of its larger size and the perception that maintenance will be more expensive, leading to faster depreciation.

For buyers seeking luxury and effortless performance, the 535i may well be one of the best bargains available in the BMW range.

Meanwhile, the 340i commands the highest prices because demand for the B58 engine continues to grow worldwide.

Final Thoughts

If outright driving enjoyment is your priority, the 335i remains one of BMW's finest driver's cars.

If you spend long hours on the motorway and appreciate refinement, comfort and effortless performance, the 535i is difficult to beat—especially considering today's attractive prices.

However, if your budget stretches to a 340i, you'll be rewarded with BMW's superb B58 engine, stronger performance, outstanding reliability and one of the best six-cylinder turbo engines the company has ever built.

No matter which model you choose, all three deliver the smoothness, soundtrack and character that have made BMW's straight-six engines legendary.

Take care!
