Electric vehicles are heavier than their internal combustion counterparts largely because of the mass of their battery packs, and that extra weight creates real challenges for ride comfort, handling, and design. Automotive engineers are working to balance the needs of comfort and dynamics as electric vehicles (EVs) grow in market share, but the solution isn’t simple. The central issue, according to industry tests, is that EV battery packs can add roughly 1,500 pounds compared with a similar gasoline-powered vehicle. That mass forces stiffer springs and suspension setups to control body motion, which in turn can transmit more road harshness into the passenger cabin, tells Design News.
Suspension engineers and OEMs are responding with a range of tactics. Larger dampers and advanced systems such as semi-active or fully active suspension can help absorb bumps and maintain better control, though these add cost and complexity. Engineers also point out that tires play a part: many EVs come with fashion-driven large wheels and low-profile tires that offer little compliance over rough surfaces, exacerbating the stiffness already required by the vehicle’s mass. Optimizing tire compounds and construction to improve compliance without sacrificing range or grip is part of the solution.
Design trade-offs extend beyond suspension hardware. Reducing unsprung mass, such as lighter wheels, can improve ride quality, but consumer demand for large wheels often outweighs engineering preference. At the same time, higher rolling resistance for range efficiency can lead to higher tire pressures, further reducing cushioning and comfort. The article notes that until battery weight itself comes down substantially, automakers must work within the limitations of current technology. Improvements in battery energy density over time could cut battery mass and make ride comfort easier to achieve without compromising range.
In the near term, achieving a comfortable, well-handling EV involves thoughtful integration of suspension design, tire selection, and consumer expectations, underscoring the complex trade-offs inherent in modern electric vehicle design.
