Bushes and electric cars: an indispensable evolution in the face of growing weight

The electrification of the vehicle fleet is profoundly transforming the technical requirements for vehicles. Among the parts heavily impacted are the suspension bushes, key elements in suspension and ride comfort. At SilentBlocks.com, we’re keeping a close eye on this development to ensure that our products are compatible and long-lasting, even in the face of the increased weight of electric cars.

What is a suspension bush and why is it essential?

A bush is a rubber or polyurethane component inserted between two metal parts. Its role is crucial:
✅ Absorb vibrations
✅ Reduce unwanted noise
✅ Preserve suspension flexibility
✅ Improving roadholding

They are found in suspension arms, engine mounts, stabilizer bars and other parts of the running gear.

The weight of electric cars is changing the game

Electric cars are on average 300 to 500 kg heavier than their internal combustion equivalents. This is mainly due to the high-capacity batteries and the reinforced structure to house them.

This extra weight has a direct impact on the running gear, and therefore on the suspension bushes, which have to withstand more mechanical stress, torsion and permanent loads. The result? Traditional bushes are no longer always sufficient.

The evolution of suspension bushes for electric vehicles

At SilentBlocks.com, we’ve incorporated the new technical requirements of EVs (electric vehicles) into our selection. The manufacturers we work with are now designing reinforced silentblocs specifically for electric cars.

✅ New generation materials

Use of high-strength polyurethanes or rubber formulated to withstand constant loads and prolonged vibrations.

✅ New design

The shapes and dimensions of the bushes have evolved to distribute loads more evenly, reduce premature wear and maintain the flexibility required for driving comfort.

✅ Enhanced durability

New-generation bushes offer superior longevity, even under the extreme constraints imposed by EVs (cold climates, heavy loads, instant acceleration…).

Why replace suspension bushes on an electric car?

Bushes can deteriorate more quickly on electric vehicles. Here are the signs of wear to watch out for:

• Clattering noises when cornering or on bumpy roads

• Unclear or imprecise steering

• Reduced driving comfort

• Uneven tire wear

• Vibrations felt in the cabin

🛠️ Preventive replacement of bushes can prevent costly suspension damage and optimize handling.
