Continental has introduced a new line of tires EcoContact 7 and EcoContact 7 S. As the name suggests, the main goal of these tires is efficiency. To achieve this goal, Continental engineers drew inspiration from golf balls.
Yes, golf balls are made with dimples to give them better aerodynamic characteristics, and it has been proven to work. Continental has taken this concept and applied it to the new tires.
The technology is called Aerodimples - hundreds of small dimples located along the entire sidewall and edge of the tread. According to engineers, this solution should reduce air turbulence behind the tire, allowing it to roll, consuming less energy.
The dimples are not the only innovative factor found in the new tires. The company uses a new Green Chili 3.0 tread rubber compound, designed specifically for low rolling resistance. In the sportier EcoContact 7 S model, the compound has been slightly modified for better grip and handling, especially in wet conditions.
The inner parts of the tire use Smart Energy Casing technology, which Continental says reduces friction, although no specific measurements are mentioned. The tread design further helps reduce rolling resistance and also reduces road noise.
As you might expect, these tires are designed for electric vehicles, where efficiency is paramount for range. However, they are also suitable for cars with internal combustion engines. The new tires are already approved for use on Volkswagen, Mercedes-Benz and BYD vehicles.
