Optim insulation is a hybrid material that combines the biostability and flexibility of high-performance silicone rubber with the strength, tear resistance and abrasion resistance of polyurethane, to provide increased durability and flexibility.
While traction batteries are heavy, and mass is bad for acceleration and agility, the lower center-of-gravity often compensates with higher levels of cornering, especially when a car wears rubber like the Signature Performance edition's sticky 21-inch summer tires.
