How to Increase the Electric Range of a Chevrolet Bolt EV with Aerodynamic Tweaks?

As electric cars become increasingly popular, one of the most pressing concerns for potential owners is the range, or how far the car can travel on a single charge. For Chevrolet Bolt EV owners, the all-electric range is impressive but there’s always room for improvement. If you’re looking to squeeze out every last mile, you’ll be happy to know there are several aerodynamic tweaks that can help.

Understanding the Science of Driving Range

Before we dive into specific modifications, let’s take a moment to understand what influences an electric car’s range. Battery capacity and energy consumption are the most direct factors, but it’s a bit more complicated than that.

The total energy an electric car can store is determined by its battery capacity, typically measured in kilowatt-hours (kWh). The Chevy Bolt, for instance, comes with a 66 kWh battery. However, not all of this energy is used to drive the wheels. Some of it powers the car’s electronics, heating, and cooling systems. The rest is used to overcome rolling resistance and air drag – the two main forces acting against your car when it’s in motion.

Reducing these two forces can significantly improve your Bolt’s range. Here are some tweaks you can apply to achieve this.

Efficient Use of Energy

Common sense dictates that the less energy you use, the longer your car’s battery will last. However, with electric cars, this idea takes on a new dimension. Beyond just turning off unnecessary electronics, there are more complex energy management strategies that can help extend your range.

Regenerative braking, for instance, is a technology that recovers energy normally wasted during braking and feeds it back into the battery. Tesla cars are well-known for their aggressive regenerative braking, but the Chevy Bolt also has a decent system. Learn to use it well, and you could add a few extra miles to your range.

Another strategy involves managing your heating and cooling. Whilst necessary for comfort, these systems can be energy hogs. Pre-conditioning your car while it’s still connected to the charger can save significant energy. The Bolt even has a setting that allows the car to draw power directly from the charger during preconditioning, so it doesn’t deplete the battery.

Optimizing Tire Pressure and Rolling Resistance

Rolling resistance is the force your car needs to overcome to keep moving. A significant part of this resistance comes from your tires. Under-inflated tires can increase rolling resistance and, consequently, energy consumption.

A good rule of thumb is to always keep your tires inflated to the manufacturer’s recommended pressure. But if you’re serious about extending your range, you can experiment with slightly higher pressures. Be cautious, though, as over-inflating your tires can lead to uneven wear and potentially unsafe driving conditions.

Low rolling resistance tires are also an option. These tires are designed to reduce energy loss, increasing your Bolt’s range. Note, however, that they can be more expensive than regular tires and may not perform as well in certain driving conditions.

Reducing Aerodynamic Drag

Just like airplane wings, cars have to be designed to slip through the air efficiently. The smoother and slicker the design, the less energy it takes to push the car forward. This is why most electric cars have a sleek, rounded design.

But if you’re looking to go beyond what the manufacturer has done, there are further tweaks you can apply. Mud flaps, for instance, can create additional drag. Removing them can help reduce this. You can also install aero wheels, which are designed to minimize air resistance.

Another major source of drag is roof racks. If you don’t need them, take them off. If you do, try to keep them empty whenever possible. The less you have sticking out of your car, the less air resistance you’ll encounter.


By now, you should have a good idea of how to extend the range of your Chevy Bolt EV. Remember that it’s not just about one big change but a series of little tweaks that add up. With careful energy management and thoughtful modifications, you can significantly increase your Bolt’s range. And the best part? Most of these tips apply to other electric cars as well.

Driving electric is a new experience, one that requires a different mindset. But once you get the hang of it, you may find it hard to go back to driving a conventional car. So get out there, try these tweaks, and see how far your Bolt can take you.

Sorry, you thought we’d end this with a conclusion? We’re taking a leaf out of the EV playbook – breaking conventions and keeping you on your toes. So, instead of wrapping things up, we’ll leave you with this thought: How much farther could you go with a little more efficiency?

Maximizing Efficiency with the Right Driving Techniques

Driving range is not only dependent on the vehicle’s design and systems but also on how it’s driven. With the right techniques, you can significantly boost the range of your Chevrolet Bolt or any other electric car.

One of the most effective methods is eco-driving. This technique involves avoiding rapid acceleration and deceleration, maintaining a steady speed, and anticipating traffic flow to reduce unnecessary braking. It’s all about smoothness and predictability. By maintaining a constant speed, you can reduce energy consumption and extend your driving range.

Similarly, cruise control can also be beneficial. It maintains a constant speed, reducing the need for acceleration and braking, which can be energy intensive. The Chevy Bolt, among other electric vehicles, comes with an adaptive cruise control feature that can adjust the speed based on the traffic ahead.

Another useful driving technique is coasting, where you let the car roll freely without acceleration. This can be especially beneficial when going downhill, where gravity can do the work for you, saving energy in the process.

Remember, every small effort can lead to significant improvements in your car’s range. These techniques, combined with the aforementioned tweaks, can help you get the most out of your Bolt’s battery.

Evaluating the Effect of External Factors on Range

The driving range of electric cars, including the Chevrolet Bolt, can also be influenced by external factors. Weather conditions, for example, play a crucial role in determining the vehicle’s range.

Cold temperatures can affect the efficiency of electric cars. The battery performance can drop in cold weather, reducing the range significantly. In chilly climates, using the heating system can further deplete the battery. Conversely, hot weather can also pose challenges as use of air conditioning can drain the battery.

Driving on rough or sloping terrains can also reduce the range as it requires more energy to overcome the resistance. The same applies to driving at high speeds, as air resistance increases exponentially with speed, leading to higher energy consumption.

In conclusion, understanding these external factors and planning your trips accordingly can help you optimize your driving range. For instance, you could pre-heat or cool your car while it’s still charging, or plan your routes to avoid steep hills or rough terrains.


Increasing the electric range of your Chevrolet Bolt EV doesn’t have to be a daunting task. By understanding the science behind the driving range and making a few strategic tweaks, you can significantly extend your car’s battery life and reduce the frequency of charges. Whether it’s optimizing tire pressure, reducing aerodynamic drag, adopting efficient driving techniques, or being mindful of external factors, these little changes can collectively have a big impact on your driving range.

Adopting an electric vehicle like the Chevy Bolt is a step towards a more sustainable future. With their increasing popularity, understanding how to maximize their efficiency is crucial. So, take these tips, get out there, and discover the full potential of your electric car. After all, the road to sustainability starts with a single charge.

Remember, the electric vehicle journey is just beginning. With evolving technology and growing awareness, the possibilities are endless. So, how much farther will you go with your Chevrolet Bolt EV?
