The latest generation of the all-electric compact Renault Twingo has been fitted with original equipment tires from Continental – 18-inch Continental EcoContact 7 – as standard worldwide.
The 18-inch tire has earned top ratings on the EU tire label for energy efficiency and rolling noise, and meets key requirements expected for electric vehicles today: low rolling resistance to help maximize driving range and low rolling noise for a quieter, more pleasant driving experience.
The EcoContact 7 achieves high energy efficiency through a new rubber compound and Smart Energy Casing technology. This technology uses new materials in the tire’s carcass, liner and sidewall to reduce internal friction and lower rolling resistance. Additionally, the tire’s aerodynamically optimized sidewall design enhances efficiency. Continental has combined several technologies to achieve this, including the Aerodimple structure borrowed from golf balls. Dimples in the sidewall reduce air turbulence behind the tire, meaning the vehicle requires less energy to keep the tire moving.
Continental has also focused on quiet driving, with the newly developed Silent Pattern tread design reducing rolling noise. Developers optimized the spacing and angles of the tread blocks to align with the noise frequencies typically generated at low speeds when driving in urban areas. As a result, the tire contributes to a quieter ride – for vehicle occupants and local residents.
