What BMW Can Be Flat Towed?

If not done properly, flat towing a BMW can seriously damage the vehicle. Each BMW owner has their own opinion on whether flat towing is safe or not—it’s really up to you to decide if you should risk it.

However, this article seeks to answer what BMW can be flat towed based on the evidence that we’ve found.

There are two very distinct realities when discussing what BMW can be flat towed. Anything from 2006 or earlier can be flat towed, as long as it’s a manual transmission and RWD.

Any BMW model that falls in this category can be flat towed for a limited distance of no more than 500 miles, and at a very slow speed. However, towing a BMW any distance further or at a faster speed can seriously damage the vehicle. It is recommended to tow a BMW using a flatbed trailer.

BMW has historically advised against flat towing. So, when looking at what BMW can be flat towed, the short answer is “none.”

Each owner must carefully consider the risks of flat towing before deciding on whether it is worth it for them and their vehicle.

What BMW Can Be Flat Towed?

Currently, there are no BMW models that can be flat towed. That’s because all of them have advanced transmissions that require constant lubrication.

Even the manual M3 cannot be flat towed, as the transmission and differential need constant lubrication. The rest of the lineup is either an automatic or AWD. These are usually not able to be flat towed, because the rolling movement damages internal components.

If you want to know what BMW can be flat towed and you’re looking at the electric models, it’s important to note that no EV can be flat towed. This happens because electric vehicles don’t have a true neutral, which is critical for flat towing.

Why Can’t The Current BMW Lineup Be Flat Towed?

BMW assembles its lineup into 10 distinct groups, and each group has its own specific guidelines when it comes to towing.

The sport type BMW are grouped in even numbers: the 2 series, the 4 series, and the 6 series. The sedan-style BMWs are grouped by odd numbers: the 3 series, the 5 series, and the 7 series. SUVs usually fall under the X category, such as the X3 and X5.

Each model has its own demands and manufacturer’s instructions, but it is a general rule of thumb that BMWs should not be flat towed. There are some exceptions, such as in the case of an emergency; there are some tricks to prevent serious damage to the vehicle.

Consult with your vehicle’s user manual before towing, but when in doubt, hire a professional to ensure that your vehicle will be safe.

What Damage Can Occur From Flat Towing A BMW?

While chances are low, flat towing can damage your vehicle and BMWs are no exception. As this article seeks to answer what BMW can be flat towed, we will also see what kind of damage occurs if you do so.

The most common form of damage caused by towing is bumper damage.

This often occurs when the hook is positioned to tow your car. Other damage can include scratches to the exterior, dents, and dings. While these are mostly cosmetic issues, other, more serious mechanical damage can also occur.

If a vehicle is left in ‘park’ when towed, the wheels will skid and shred on the road, and the linkage that leads to the transmission will be damaged. For this reason, all vehicles should be placed in ‘neutral’ when towed.

When towed in any gear besides neutral, a vehicle with manual transmission or automatic transmission can be seriously damaged. However, automatic transmissions will not disengage the wheels, even when in neutral, so towing could force the transmission to go into a direction that it can’t turn. The wrong movement can prevent the oil from moving through the gears and transmissions.

What Damage Can Happen To The Electric Motor When Flat Towing A BMW?

Now, a big factor contributing to the answer to what BMW can be flat towed is no is that they are electric vehicles. For example, some of the BMW 3 and 4 series have electric motors.

Guidelines for these cars say the vehicle should not be towed by its axles, except in extreme circumstances. In emergency situations, they can be pulled slowly over a short distance, and only when the vehicle is in neutral gear.

If improperly towed, the electric motor could supply current to the high-voltage system. This means towing with the tires on the ground, spinning, and creating more voltage than the system can take. This will cause damage to the motor and transmission.

It’s an expensive fix, and chances are that the dealership won’t cover it under warranty.

Can You Damage A BMW Transmission When Flat Towing?

The short answer is, “yes.” However, there are some nuances.

When looking at what BMW can be flat towed, you will see that towing a BMW with manual transmission would be all right, as long as you follow the manufacturer’s guidelines.

However, flat towing a BMW with automatic transmission will tear up the transmission because the wheels are running but the transmission oil pump isn’t working.

If towing is your only option, you can avoid this damage by removing the driveshaft. The drive shaft moves the torque from the engine to the wheels. When the drive shaft is removed, the vehicle is technically out of gear, and the tires can roll without affecting the engine or transmission.

The problem with this strategy is that learning how to remove the driveshaft requires several hours. Plus, with many BMWs being so low to the ground, it’s a hassle to do. Not only that, doing so in a new BMW could void your warranty.

No matter which way we look at it, the overwhelming answer to what BMW can be flat towed is that none of them should be.

Can Wheels Get Damaged When Flat Towing?

When flat towing, all four wheels turn. As a result, the drivetrain and transmission can be damaged.

If you tow a BMW with all four wheels in contact with the pavement, the wheels can drag. To prevent this, keep the ignition on, and the car in neutral.

This way, the tires can still spin. This, however, can come with its own problems if you are not careful.

It is not recommended, but if you tow your BMW on only its back tires, you risk frying your transmission.

How Can You Tow A BMW?

One common discussion you could find goes like this: “if the answer to what BMW can be flat towed is that none can be, then why does it have tow hooks?”

Most BMW models have threaded holes on the bumper where the tow hooks should be attached. Tow hooks are used to secure the towing chain or strap and to distribute the force of the pull along the frame of the vehicle.

These points are ideal for pulling the vehicle out of a ditch, or to help in placing it on a trailer. They’re only to be used in an emergency.

While towing a BMW, it is important to have a tow bar. The tow bar mates to the tow hook and will distribute the weight of your vehicle more evenly. Choose a tow bar that is rated for more than your BMW weighs to compensate for any extra equipment or luggage.

Towing with improperly installed tow hooks and bars could have disastrous results and should never be attempted. There is a high risk of the car veering while being towed, which can lead to a wreck and further damage to your vehicle. Be sure your equipment is properly in place, or you can cause front-end damage and ruin the alignment of your tires.

Closing Thoughts To What BMW Can Be Flat Towed

The reality is that no BMW can be flat towed. You could take a chance with the older models, but it’s still a risk.

Be sure to cover the flat towing laws in your area, as well as any area you are traveling to; the laws can vary from state to state.

Make sure that the vehicle doing the towing can handle the full weight of your BMW, including any extra equipment or luggage.

With this information, you can make a more informed decision about whether or not to flat tow your BMW.
