Urban traffic is characterized by constant stop and go. This causes torsional deformation of the tires in response to the applied torque, causing energy to dissipate in the process. The Conti CityPlus technology is designed to improve total energy efficiency under these kinds of driving conditions by up to ten percent. And with the same very low rolling resistance levels. This is especially beneficial for electric vehicles because their higher torque and weight additionally amplify energy loss in tires. 

The Conti CityPlus is based on Continental's EcoContact 6 series tire. It has been specially engineered to offer high mileage and low rolling resistance. To achieve higher overall energy efficiency, the concept tire includes a range of modifications designed to reduce tire deformation during braking and acceleration. The tread strip features a special V-shape pattern, which creates a stiffer pattern structure. In addition, a new construction method results in a stiffer carcass which reduces tire deformation. The special system of fillers and an optimized polymer network in the rubber compound also contribute to the tire’s high overall energy efficiency.
