The shift to electric and hybrid drivetrains is redefining how vehicles are designed, built, and experienced. With higher demand for noise, vibration harshness, and the increasing reduction of compact architectures, traditional solutions for vibration and load control are being pushed to their limits.This development demands smarter components that can balance performance, durability, and efficiency without adding unnecessary complexity.
At Angst+Pfister, we’ve reimagined the differential mount for this new era. By combining innovative elastomer compounds with a simplified, integrated design, our engineering team has created a solution that not only tackles high-frequency vibration challenges but also helps OEMs streamline assembly, reduce weight, and cut costs. The result is more than a component upgrade: it’s a step toward the next standard in drivetrain technology.
The Challenge: High-Frequency Vibrations in Modern Drivetrains
As electric, hybrid, and autonomous vehicle platforms become more sophisticated, one challenge remains stubbornly persistent: managing noise vibration harshness (NVH) in high-frequency environments. Traditional differential mounts, often based on standard rubber compounds and outdated axial snubbing designs, struggle to keep up.
Especially in electric powertrains, high-frequency excitations lead to hardening of elastomer components. This causes unwanted vibrations to transfer into the chassis, undermining comfort and creating a noticeable disconnect between vehicle performance and driving experience.
The Solution: Smarter Mount Design and Fewer Components
Enter Angst+Pfister’s newly engineered differential mount, developed specifically for the demands of modern mobility systems. Developed by our powertrain engineering experts, this mount features:
- Ultra-low hardening compound at high frequencies: For superior vibration isolation
- Integrated axial stopper: No separate snubber discs or washers needed
- Proprietary inward-folded outer tube geometry: Functional integration at its best
“Through rethinking rubber, metal, and geometry, we created a solution that challenges the traditional mount design.”

Use Case: Smoother Rides for High-Performance EVs
In a recent project, we worked on a high-end electric sports car. The goal was to provide great comfort and to keep noise low during tough driving conditions.
The Angst+Pfister differential mount was selected for this project due to its ability to:
- Minimize high-frequency transmission into the passenger cabin
- Fit within a tight packaging envelope
- Reduce component count for more efficient assembly
The result: A quieter, more refined driving experience without compromising durability or mechanical protection.
Supply Chain & Production Benefits
The new advanced differential mount with integrated axial snubbing performs better, streamlines manufacturing, and simplifies supply chains:
- Fewer parts per unit: Reduces BOM complexity and inventory overhead
- Integrated design: Lowers assembly time and tooling cost
- Durability: Increases service intervals and lowers lifetime cost
Why It Matters for Procurement and Engineering
Engineers value the integration of NVH comfort and robust axial protection without added mechanical parts.
Procurement professionals appreciate the reduction in total cost of ownership through weight savings, simplified logistics, and higher production efficiency.
And for both, it supports the broader move toward smart, compact, and integrated drivetrain components: absolutely crucial in the age of electrification and rapid developments in off-highway and agricultural machinery.
Electrification Trends in Agriculture and Construction
Electrification is no longer confined to passenger and commercial vehicles; it is increasingly shaping the future of agriculture and construction machinery as well.
Key developments include:
- Alternative drivetrains are emerging as central solutions for decarbonizing construction sites and agricultural operations.
- Electric motors have become established technology for compact equipment such as excavators, loaders, rollers, dumpers, and compactors.
- Leading manufacturers are setting ambitious timelines, with some pledging to phase out fossil-fuel-powered vehicles by 2040.
- Market research projects show that the global electric construction machinery market could exceed $100 billion by the early 2040s.
Battery-electric systems are currently best suited for compact machines, where daily energy needs are manageable and charging strategies can be efficiently implemented. For larger and heavier machinery, electrification still faces technological and economic barriers, though steady progress is being made.
Hydrogen-powered machinery is also gaining traction, with prototypes of hydrogen combustion engines and fuel-cell-based systems signaling potential for broader adoption in the near future.
At the same time, alternative fuels such as hydrotreated vegetable oil (HVO) offer additional pathways to reduce emissions, particularly for use cases like mobile cranes, where life cycle analyses indicate significant CO₂ savings.
The pace of adoption will ultimately depend on overcoming critical challenges around infrastructure, sourcing, and scalability. To deliver meaningful environmental benefits, supply chains for electricity, hydrogen, and alternative fuels must be both sustainable and widely accessible.

Frequently Asked Questions About Hydrogen Safety
1. What NVH challenges do electric and hybrid drivetrains pose that traditional differential mounts struggle to address?
Electric and hybrid drivetrains generate significantly more high-frequency excitations compared to internal combustion systems. Traditional differential mounts, typically designed with standard rubber compounds and separate axial snubbers, tend to harden under these frequencies. This hardening transmits unwanted vibrations directly into the chassis, resulting in increased noise, harshness, and a less refined driving experience. As vehicles become quieter overall, these vibrations become even more noticeable, making NVH control a critical design priority.
2. How does the new Angst+Pfister differential mount improve NVH performance?
Our new mount uses an innovative low-hardening elastomer compound combined with a fully integrated axial stopper. This design cuts high-frequency hardening by about 20%, enabling superior isolation of high-frequency vibrations. By preventing these vibrations from reaching the passenger cabin, the mount delivers a smoother, quieter ride – even in high-performance EV applications – while also protecting drivetrain components from premature wear.
3. What makes this mount more efficient and lightweight compared to conventional solutions?
We re-engineered the mount’s metal geometry and functional integration to eliminate separate components like snubber discs or washers. This resulted in about 20% weight reduction and a single-piece design that simplifies assembly steps. Fewer components mean faster production, less tooling, and lower inventory complexity, all while improving durability and extending service intervals.
4. How do sealing solutions reduce the risk of accidents?
Electrification demands smarter, more compact, and more efficient drivetrain components. Our mount’s lightweight design helps lower overall vehicle weight, supporting energy efficiency and longer range. By simplifying the bill of materials and improving durability, it also reduces material usage, production waste, and logistics overhead. These factors align with the industry’s broader push for eco-efficient, low-emission, and sustainable solutions, especially in emerging markets like electric construction and agricultural machinery.
5. What are the benefits for both engineering and procurement teams adopting this new differential mount?
For engineers, the mount offers integrated NVH comfort and robust axial protection without added mechanical complexity – enabling them to meet strict packaging and performance targets. For procurement teams, it reduces total cost of ownership through fewer parts, lower assembly time, lighter weight, and longer service intervals. Overall, it accelerates production efficiency while helping OEMs achieve both cost and quality targets in next-generation EV and hybrid platforms.
