Let’s break down the key components that contribute to the overall reliability of this model, so you know what to expect when you hit the road.
Engine Performance
The heart of the 740i is its 3.0-liter inline-six engine, equipped with BMW’s TwinPower Turbo technology. This engine is known for its smooth power delivery and impressive acceleration. However, some owners have reported issues related to oil consumption and coolant leaks, which can lead to more significant problems if not addressed promptly. Regular maintenance is essential to keep this engine running smoothly, so make sure to keep an eye on oil levels and service intervals.
Transmission Durability
The 740i comes with an 8-speed automatic transmission that generally receives high marks for its responsiveness and smooth shifting.
