Most efficient Mercedes ever riding on Bridgestone tyres

Progressing from white paper to completed vehicle in just 18 months, Mercedes-Benz says it is “setting new standards for electric range and efficiency” with the Vision EQXX. This prototype car can potentially travel more than 1,000 kilometres or 620 miles on a single battery charge, which equates to consumption of less than 10 kWh of energy per 100 kilometres – an efficiency of more than 6 miles per kWh. Mercedes-Benz attributes this generous range to numerous factors, including an exterior design that offers a benchmark drag coefficient of 0.17, as well as lightweight design that sees the Vision EQXX weigh in at around 1,750kg, battery innovations developed together with Mercedes-AMG High Performance Powertrains, and new materials. Ultra-low-rolling-resistance tyres with optimised aerodynamic geometry also combine with lightweight magnesium wheels for increased range.

The tyres are a tailored version of the Bridgestone Turanza Eco. Engineers from Mercedes-Benz worked in cooperation with Bridgestone to develop tyres for the Vision EQXX. In addition to including Bridgestone’s Enliten and ologic technologies, the tyre design also features aerodynamically optimised sidewalls to match the covers mounted on the 20-inch, lightweight, forged-magnesium wheels. These wheel covers, incidentally, are of a semi-transparent double-spoke design that pair with an air curtain/air breather at the car’s front bumper to “remove almost every last whisper of aerodynamic separation” from the front wheels.
