BMW M4 G82/G83 Buying Guide

BMW M3/M4 G80/G82 Buying Guide

The BMW M3/M4 G80/G82, equipped with the powerful S58 engine, marks the latest generation of the M3/M4 lineage. Launched in the last few years, the M3/M4 G80/G82 brings substantial improvements over their predecessor, blending performance, precision, and technology in a more aggressive and modern package. With its 3.0-litre twin-turbocharged inline-six engine, the M3/M4 offer impressive power and handling, making them a popular choice among performance enthusiasts.

If you're considering purchasing a used M3/M4 G80/G82 with the S58 engine in the UK, this buying guide will provide the essential details to help you make an informed decision. Although these cars are relatively new to the market, there are still some key considerations to keep in mind, especially when it comes to performance vehicle ownership.

Pre-LCI vs. LCI Models

The M3/M4 G80/G82 come in two main variants: Pre-LCI and LCI models. The term "LCI" stands for "Life Cycle Impulse," which refers to a mid-life facelift that typically includes changes to design, features, and sometimes performance. As they are relatively new models, any potential differences between the Pre-LCI and LCI versions are more likely to involve minor updates rather than major changes.

• Pre-LCI Models (2022-2023): The initial production models of the G80/G82, featuring the latest S58 engine but with the original design and features as seen in the 2022 release.
• LCI Models (2024 and onwards): The facelifted versions will feature updates such as revised headlights, new technologies, or tweaks to the interior. Check with the dealership or seller to verify the exact details of the LCI changes, as they may affect pricing or feature availability.

For buyers, the key considerations when distinguishing between Pre-LCI and LCI models will mostly centre on design preferences and feature updates, rather than significant differences in performance or reliability. Please note the dates above are for new build vehicles, there are quite often Pre-LCI models that have not been registered that may fall into 2024, check with your dealer to be sure. 

S58 Engine Performance

The M3/M4 G80/G82 are powered by the S58 engine, which is known for its strong and reliable performance. With around 453bhp (470hp in some markets) and 550Nm of torque, the S58 provides plenty of power for daily driving as well as thrilling track performance. Thanks to its twin-turbo setup, the engine delivers strong low-end torque and high-revving performance, making it a joy to drive.

Given that they were released only in 2022, the engine has not had time to show any widespread reliability issues. The S58 engine is an evolution of the S55, known for being both powerful and dependable, and it has been used in various BMW M models, including the X3 M and X4 M. The S58 also shares parts and configurations from the B58 engine, another highly reliable performance motor. 

Buying Considerations for the M3/M4 G80/G82

Whilst the M3/M4 G80/G82 are relatively new models, it’s important to follow the standard checklist for purchasing any performance-oriented vehicle to ensure you're getting the best possible example.

1. Service History and Documentation

Ensure that the car you are considering has a comprehensive service history, even if it is relatively new. The car should have undergone its regular scheduled maintenance, and you should check for any signs of neglect or missed service intervals. BMW vehicles come with a scheduled maintenance plan, so it’s essential to ensure that the car has adhered to these guidelines.

If the car is being sold by a private seller, ask for any receipts or records of maintenance. This can be particularly important for performance cars, as modifications or track usage may influence the condition and value of the car.

New M-Cars are required to have a "running-in service" usually around 1200 miles. BMW owners often frown upon cars that have missed this service, or had this service late. Check the iDrive Service History of the vehicle to make sure this has been carried out. 

2. Modifications and Aftermarket Parts

Many performance car owners tend to modify their vehicles, and the M3/M4 G80/G82 are no exception. When inspecting a potential purchase, pay attention to any aftermarket modifications, especially to the engine, suspension, or exhaust system. While modifications can be exciting and may improve performance, they can also affect the car’s long-term reliability.

If the car has been modified, ensure the work has been done professionally by a reputable company. Modifications should be documented, and it's worth ensuring that any changes are reversible if you're looking for a more standard driving experience.

3. Track Use and Wear

Performance-oriented cars like M-Cars are often used on track days, which can cause accelerated wear on certain components. Even though the car is relatively new, it’s still worth checking for signs of heavy use. Here are a few areas to check:

• Suspension: Track driving puts significant strain on suspension components. Listen for any knocking or clunking noises when driving, as these may indicate worn bushings, control arms, or dampers.
• Tyres: Check the condition of the tyres for any signs of uneven wear, especially on the inner edges. Inner tyre wear is often a sign of aggressive cornering or misalignment, common in cars driven hard on track days.
• Brakes: Inspect the brake pads and discs for excessive wear. Track driving can cause brakes to wear quickly, so make sure the braking system is in good condition.

If the M3/M4 G80/G82 you're considering has been used heavily on track, it's important to ensure that the brakes, suspension, and tyres have been properly maintained or replaced.

4. Engine and Transmission Health

The S58 engine is known for its reliability, but as with any high-performance engine, it’s essential to ensure that it’s in good condition. When inspecting the car, pay attention to the following:

• Oil Changes: Regular oil changes are crucial to the health of the engine, particularly in turbocharged engines. Check the service history for confirmation that the oil has been changed at the recommended intervals.
• Transmission: Whether the car is equipped with the manual gearbox or the 8-speed dual-clutch automatic, ensure that the transmission operates smoothly without any hesitation, grinding, or jerky shifts.

If the car has been driven hard, be sure to check the clutch (if manual) and the gearbox for signs of wear.

Common Problems and Considerations

As the M3 and M4 are relatively new, there are no widespread or common issues reported at this time. However, some general considerations for any performance vehicle still apply:

• Cooling System: High-performance engines like the S58 generate a lot of heat, particularly when driven hard. While they are designed with an advanced cooling system, it’s always worth checking that the system is functioning properly, particularly if the car has been used on track.
• Brake Fluid and Clutch Fluid: As with any performance car, it's important to ensure that both brake and clutch fluids are regularly maintained. If the car has been used on track, fluid should be checked or replaced, as high temperatures can cause fluid degradation.
• Warranty and Recalls: M3/M4's may still be under BMW’s warranty. If buying from a dealership, check if any extended warranties are available or if there are any outstanding recalls.

Conclusion

The BMW M3/M4 G80/G82's with the S58 engine are exciting and capable performance cars that offer thrilling driving dynamics. While these vehicles are still new, it’s important to consider the usual factors when purchasing a performance car, including service history, potential modifications, and any signs of heavy use.

Whether you're considering a Pre-LCI or LCI model, the M3/M4 G80/G82 represents an exceptional blend of performance and technology. By following the standard buying checklist and paying attention to key details such as suspension, engine health, and track use, you can ensure that your M3 or M4 continues to deliver a rewarding driving experience for years to come.
