The BMW X3 G01 is the third generation of BMW's mid-size SUV, built from 2017 to 2024. It offers a spacious interior, xDrive all-wheel drive in most versions and a wide range of engines, from economical diesels to the powerful M Performance models.
It is a popular family car and a strong used buy. In this buying guide we explain the engines and versions, practicality, the points to check and what to look for when buying a G01 X3.
Why the G01 X3 is popular
The G01 X3 offers:
- Space and comfort for five people.
- A large boot and practical interior.
- xDrive all-wheel drive on most versions.
- A wide choice of engines.
- Good driving dynamics for an SUV.
- Towing capability.
It is an all-rounder that suits families, long-distance drivers and those who need a capable car in winter.
The G01 is larger and more refined than the previous F25 X3, with a more modern interior and better driver assistance systems. On the road, it feels composed and comfortable, with precise steering for an SUV. Many owners say it combines the practicality of a family car with the driving feel they expect from a BMW.
Engines and versions
The G01 X3 was offered with many engines, depending on the market:
- Petrol: xDrive20i and xDrive30i with the B48 four-cylinder. Our article on the BMW B48 engine explains it.
- Diesel: xDrive20d with the B47 four-cylinder and xDrive30d with the B57 six-cylinder. Our articles on the B47 and B57 diesel explain them.
- Plug-in hybrid: xDrive30e. Our article on BMW plug-in hybrids explains how it works.
- M Performance: M40i with the B58 petrol six-cylinder and M40d in some markets. Our article on the BMW X3 M40i explains it.
- Full M: the X3 M with the S58.
A fully electric version, the iX3, was also built on a related platform in some markets.
Updates during production
The X3 was updated around 2021 with revised styling, a larger kidney grille, new lights, an updated interior and new technology. Mild hybrid technology was added to several engines.
Many buyers prefer updated cars for their improved equipment and refinement, but earlier cars can offer good value.
When comparing cars, check the production date and equipment list rather than relying only on the year of registration. Some cars registered after the update were built before it, and the reverse can also happen.
Practicality
The X3 is one of the most practical cars in its class:
- A large boot with split-folding rear seats.
- Good rear legroom.
- An electric tailgate on many cars.
- Roof rails for roof boxes and bike carriers.
- Towing in many versions. Check the approved trailer weight in the documents.
It is ideal for families, holidays and outdoor activities.
BMW X3 G01: points to check
The G01 X3 is generally reliable, but check:
- Service history and oil changes.
- DPF and AdBlue on diesel models, especially those used for short trips. Our articles on the BMW DPF and BMW AdBlue explain these systems.
- Hybrid system and charging on the xDrive30e.
- Coolant and oil leaks on high-mileage cars.
- xDrive and gearbox for smooth operation.
- Panoramic roof drains on cars with a large sunroof.
- Software updates for infotainment and driver assistance. Our article on BMW Remote Software Upgrade explains updates.
Equipment worth looking for
Popular options include:
- Adaptive LED headlights.
- Head-Up Display. Our article on the BMW Head-Up Display explains it.
- Driving Assistant Professional. Our article on BMW Driving Assistant Professional explains it.
- Parking Assistant Plus.
- Comfort Access and an electric tailgate.
- M Sport package and adaptive suspension.
A well-equipped X3 is comfortable, safe and easier to sell later.
Cars with the M Sport package look sportier and often have firmer suspension and larger wheels. If comfort is a priority, test drive cars with different wheel sizes, because large wheels with low-profile tyres can make the ride firmer on poor roads. Adaptive suspension, where fitted, offers a good balance between comfort and control.
Test drive checklist
On the test drive:
- Check for warning messages.
- Test the gearbox and xDrive in slow, tight turns.
- Listen for noises from the suspension.
- Test all driver assistance and parking systems.
- Read the fault memory.

Is the G01 X3 a good buy?
The G01 X3 is one of the best all-round family SUVs on the used market. For mostly short trips, choose a petrol or plug-in hybrid. For long distances and towing, a diesel such as the xDrive30d is excellent.
Many cars still have warranty or approved used cover. Our article on BMW extended warranty explains options. Our article on BMW diesel or petrol helps you choose the right engine.
