Continental and Renault Partnership Develops Tires That Boost EV Range by Up to 30 km

Rolling resistance reduction

35%

Additional range per charge

30 km

Test tires saved annually

10,000

What Happened

Continental has developed a highly efficient tire for Renault that reduces rolling resistance by up to 35% compared to the EU tire label's top A rating. For a vehicle with a 500-kilometer battery range, this translates to approximately 30 extra kilometers per charge. The tire is based on the EcoContact 7, adapted with a modified tread compound, sidewall design, and optimized construction.

Rolling resistance reduction

35%lower than EU A-rating requireme

Directly translates to extended EV range.

“Together with Renault Group, we are improving the efficiency of its new electric vehicles. Our tailor-made tires have very low rolling resistance, which significantly increases range.”

— Dr. Christian Strübel, Continental expert on rolling resistance

Key benefits of the collaboration

Up to 30 km additional range per charge
Up to 35% lower rolling resistance than EU A-rating
Use of virtual simulators to reduce physical prototypes
Continental saves up to 10,000 test tires annually

Why this matters

Tires are a key factor in EV energy efficiency; this partnership shows how tire innovation can directly improve driving range, a major concern for EV buyers.

Rolling resistance: The energy lost as a tire deforms and creates friction while rolling, which affects fuel or battery efficiency.
EU tire label: A European Union classification that rates tires on rolling resistance, wet grip, and noise to help consumers choose efficient and safe tires.
Driver-in-the-Loop simulator: A virtual testing system that allows engineers to evaluate tire performance with a human driver in a simulated environment.
