Conti to introduce winter EV tyre
Starting in autumn 2013, Continental will produce a winter tyre for electric cars. The company previewed this tyre, the Conti.eContact Winter, at the Geneva Motor Show and shared that it can cut rolling resistance considerably compared with its standard equivalent. “The 20-inch size was decided upon due to rolling resistance and wear criteria,” commented Alexander Bahlmann, head of media and public relations for Continental’s Tires division. “It was the best size in comparison to a standard winter tyre; rolling resistance has been reduced by 25 per cent compared with a 16-inch tyre.”
This large but very narrow tyre features a new sidewall design that offers enhanced aerodynamics. By greatly reducing rolling resistance, Continental aims to cut the energy required by electric cars and thus extend the operating range of this new type of vehicle. In winter, there is a particular need for low rolling resistance as, in addition to what the powertrain requires, more energy is needed for heating and headlights than during summer. Continental states that the extended range made possible by the tyres will significantly boost end-consumer acceptance of these vehicles, while at the same time reducing the energy used and battery charge times.
Continental says the driving characteristics of the Conti.eContact in typical wintry conditions are on par with those of standard Continental winter tyres. Bahlmann explained that the tyre maker’s design priorities were a good level of braking and safety plus good rolling resistance, and according to Continental the tyre “displays excellent braking properties on wet road surfaces and delivers the same level of protection against aquaplaning as conventional winter tyres from Continental.”
The Conti.eContact will initially be produced in size 195/55 R 20 and is suitable for both electric and hybrid vehicles.
