Buying Guide for the BMW M135i F40

The BMW M135i F40, introduced in 2020, is BMW's high-performance compact hatchback. Built on BMW's front-wheel-drive-based platform, it offers a departure from its predecessor’s rear-wheel-drive setup. For prospective buyers, this guide provides insights into what to look for when purchasing a new or used M135i, along with considerations for those who may plan to modify their vehicle.

Overview of the BMW M135i F40

  • Engine: 2.0-liter inline-4 turbocharged engine, delivering 306 hp and 450 Nm of torque.
  • Drivetrain: BMW xDrive all-wheel-drive system, ensuring excellent traction and stability.
  • Transmission: 8-speed automatic, providing smooth and quick shifts.
  • Interior: Premium materials, with advanced technology such as BMW’s iDrive infotainment system and digital instrumentation.

Although the F40 is still relatively new, here are factors to consider when purchasing either a new or used M135i.

Buying Considerations

1. Vehicle History and Condition

For pre-owned models, confirm the vehicle’s maintenance history and overall condition:

  • Service Records: Ensure that all routine maintenance has been performed according to BMW’s schedule (e.g., oil changes, brake fluid replacements).
  • Warranty: Many M135is from 2020 onward will still be under BMW’s factory warranty. Verify coverage details and remaining terms.
  • Accident History: Use a VIN check service to confirm the car’s accident-free status.

2. Known Issues to Watch For

While the M135i F40 is generally reliable, some areas deserve attention:

  • Tires and Suspension: The M135i's sporty nature may lead to tire and suspension wear, especially if driven aggressively. Inspect for uneven tire wear or suspension noises.
  • Interior Electronics: Check that all electronics, including the infotainment system, digital displays, and driver aids (e.g., adaptive cruise control), are functioning correctly.
  • Brakes: Inspect brake pad and rotor wear, as the M135i’s performance capabilities can lead to faster consumption of these components.

3. Mileage and Usage

The M135i is often used as a daily driver or performance vehicle. Ensure the car has been used appropriately:

  • Low-Mileage Cars: These are ideal for a new-owner-like experience, though ensure low mileage matches overall condition.
  • High-Mileage Cars: If mileage exceeds 30,000 miles, verify maintenance for wear-prone items such as the turbocharger, suspension, and fluids.

4. Modifications

Some M135i models may have been modified by previous owners. While modifications can enhance performance, they may affect reliability, resale value, and insurance:

  • Quality of Modifications: Check for reputable brands and professional installation, particularly for performance parts like ECU tunes, exhaust systems, or upgraded suspensions.
  • OEM vs. Aftermarket: Many buyers prefer OEM components for reliability. If modifications are present, ask if the original parts are included.

Key Features to Consider

When selecting an M135i, ensure the configuration aligns with your needs:

  • Options and Packages: BMW offered various options for the M135i, such as premium audio systems, adaptive suspension, and enhanced driver-assistance features. Verify included packages like the M Sport Pro Pack or Technology Pack.
  • Color and Trim: Some paint colors and interior trims may be more desirable, affecting resale value.
  • Wheels and Tires: The M135i typically comes with 18-inch or 19-inch wheels. Check the condition of the tires and ensure they are suitable for your driving environment.

Cost Considerations

Running Costs

  • Fuel: The M135i uses premium gasoline and achieves an average of around 30 mpg. However, spirited driving or modifications can reduce fuel economy.
  • Maintenance: Routine service costs for oil changes, brake pads, and inspections are comparable to other vehicles in its class, though premium parts may increase costs for wear-and-tear items. Check out our Maintenance Guide here
  • Insurance: Insurance costs may be higher due to the M135i’s performance classification. Modified cars may further increase premiums.

Tips for Test Driving

When test-driving the M135i, pay close attention to these areas:

  • Engine Performance: Acceleration should feel smooth, with no unusual turbo lag or hesitation.
  • Steering and Handling: The steering should feel precise and responsive. Check for any pulling or instability at higher speeds.
  • Brakes: Ensure firm and predictable braking with no vibrations or squealing.
  • Ride Comfort: The suspension should provide a balanced ride. Test different drive modes (e.g., Comfort, Sport) to experience the car’s versatility.

Is the M135i Right for You?

The M135i is ideal for buyers looking for:

  • A high-performance hatchback with everyday usability.
  • All-wheel-drive capability for year-round driving confidence.
  • Modern technology and premium features in a compact package.

However, buyers seeking a more traditional BMW rear-wheel-drive experience may prefer other models in the lineup.

Conclusion

The BMW M135i F40 is a compelling choice for those seeking a premium, high-performance compact car. By inspecting the vehicle thoroughly, verifying maintenance records, and considering your preferences for features and modifications, you can ensure a rewarding ownership experience.
