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.
