Can You Reduce the Kerb Weight of a Lotus Evora for Better Power-to-Weight Ratio?
When you look at the Lotus Evora, you already see a lightweight sports car with a balance of power and agility. But, is it possible to reduce the kerb weight of this sporty vehicle for an even better power-to-weight ratio? Let’s delve into this topic and explore the possibilities.
Can the Lotus Evora Be Lightened Further?
To begin, let’s discuss the standard specifications of the Lotus Evora. As a sports car, it’s already designed with weight considerations in mind. Its lightweight construction makes it a favorable choice among performance enthusiasts.

The Lotus Evora weighs 3149 lbs. or 1429 kg. It has a power output of 276 bhp and can go from 0-60 mph in just 4.9 seconds. The car’s kerb weight is distributed in a 38:62 front-rear ratio. The body is primarily made of aluminum and composite materials, contributing to the lightweight nature of the car. However, when it comes to further reducing the car’s kerb weight, there are a few options.
Performance Parts
One option for reducing the weight of the Lotus Evora is to replace some of the standard parts with performance parts. This can include switching out the stock wheels for lightweight alloy wheels or replacing the seats with racing versions.

For instance, the standard wheels of the Evora are made of aluminum alloy. While these wheels are already light, there’s a possibility to switch them with carbon fiber wheels. Carbon fiber is lighter than aluminum and equally strong, thus reducing the overall weight without compromising the integrity and safety of the car.
The same goes for the seats. The standard Evora seats are comfortable and ergonomically designed, but racing seats are generally lighter and designed for sports performance.
Carbon Fiber Body Parts
Another way to reduce weight is by replacing some of the body parts with carbon fiber. The standard Lotus Evora already incorporates some carbon fiber in its construction, but further utilization of this material can potentially reduce the weight of the car.
The front and rear bumpers, for instance, are significant parts where weight can be cut. Carbon fiber bumpers are lighter than their aluminum counterparts, and they also offer excellent resistance to damage.
Moreover, the hood and the trunk lid can also be replaced with carbon fiber parts. Even the door panels can be switched to lightweight carbon fiber. All these modifications can contribute to a significant reduction in the overall weight of the car.
Will Reducing Weight Improve Performance?
Now, the real question is, will reducing the weight of the Lotus Evora improve its performance? The answer largely depends on the extent to which the weight is reduced and how it affects the car’s balance and handling.
A lighter car benefits from an improved power-to-weight ratio, which can result in faster acceleration and higher top speed. However, it’s essential to consider that the weight distribution of the car can also be affected by these modifications – and this can alter the car’s handling characteristics.
Handling and Balance
If you think about it, the Lotus Evora is already a well-balanced car with its 38:62 front-rear weight distribution. This balance contributes to the car’s exceptional performance on the road and track. However, if the weight reduction is not evenly distributed, it could lead to a change in this delicate balance, potentially affecting the car’s handling.
For instance, if more weight is removed from the rear than the front, it could lead to a change in the car’s center of gravity, which may affect handling. Therefore, when considering weight reduction, it’s essential to ensure that the weight loss is evenly distributed throughout the car.
Power-to-Weight Ratio
Apart from handling, the other significant factor that’s affected by weight reduction is the power-to-weight ratio. A lower weight means the engine has less mass to move, which can result in quicker acceleration and a higher top speed.
With a standard weight of 1429 kg and a power output of 276 bhp, the Lotus Evora already has a good power-to-weight ratio. But, if you were to reduce the weight of the car by, say, 100 kg, the power-to-weight ratio would improve, resulting in even better performance.
What About the Lotus Emira?
Within the Lotus family, the Emira is the latest sports car that has made headlines for its performance and design. With a kerb weight of 1405 kg and a power output of 296 bhp, the Emira also boasts a favorable power-to-weight ratio.
Like the Evora, the Emira also makes use of composite materials and aluminum in its construction. However, if you’re considering modifying a Lotus to reduce weight, you might wonder whether the same principles apply to the Emira.
The answer is yes. The same modifications that can be done to the Evora, like replacing standard parts with carbon fiber or lightweight alloys, can also be applied to the Emira. However, as with the Evora, you’ll need to consider how these changes will affect the car’s balance and handling.
The Lotus Emira and Evora reflect the Lotus brand’s commitment to lightweight design and high performance. While these cars already offer an impressive power-to-weight ratio, there is potential to further improve these figures by reducing the kerb weight. However, any modifications should be done with careful consideration for the car’s balance and handling characteristics.
Enhancements in the Interior and Other Parts
In addition to the major components mentioned above, minor tweaks in the interior and other parts of the Lotus Evora can contribute to weight reduction. This could be as simple as removing the rear seats or replacing the steering wheel with a lighter one.
The default Evora sport steering wheel, for instance, can be replaced with a carbon fibre steering wheel. Not only is carbon fibre lighter, but it also offers the driver a better grip, making it an excellent choice for a sports car. The reduction in weight might be minimal but every little bit counts when working to improve the power-to-weight ratio.
The same principle applies to other parts of the car’s interior. The floor mats, door panels, and dashboard components can all be replaced with lighter materials. Lotus exclusive components like lightweight aluminium shift knobs and foot pedals can make a significant difference in the overall weight.
One common practice among sports car enthusiasts is the removal of non-essential parts. This includes the air-conditioning system, the stereo, and in some cases, the rear seats. While this might not contribute to comfortable everyday driving, it certainly benefits the power-to-weight ratio on track days.
Conclusion: Balancing Power, Weight, and Comfort
To sum up, it is certainly possible to reduce the kerb weight of a Lotus Evora to achieve a better power-to-weight ratio. Replacing standard parts with carbon fibre or lightweight aluminium, removing non-essential components, and implementing Lotus exclusive parts can all contribute to weight reduction. However, it’s crucial to remember that these modifications should not compromise the car’s balance and handling.
The Lotus Evora is already an excellent sports car with a favourable power-to-weight ratio. Any modifications made to enhance this ratio should be done carefully and with expert guidance. This is to ensure that the balance between the front rear weight distribution is maintained while maximizing power output.
Meanwhile, the same principles can be applied to other Lotus cars, such as the Lotus Emira. Again, the key lies in preserving the vehicle’s balance and handling while working towards weight reduction.
Overall, the quest for the optimal power-to-weight ratio in a sports car like the Lotus Evora or the Lotus Emira requires a delicate balance. It’s not merely about reducing weight but ensuring that the car’s performance and handling characteristics are preserved, if not improved. That’s the beauty of driving a Lotus – experiencing the thrill of top speed and unparalleled handling in a lightweight, agile package.
In the end, the best thing about owning a Lotus is the ability to customize and fine-tune it according to your preferences. Whether you’re aiming for a speed mph record or just want a more responsive driving experience, there are plenty of options to make your Lotus truly yours.
