Après la sortie en 2008 du Bridgestone Ecopia EP100, et de l'ER300 Ecopia en Avril 2009 (Février pour l'OE), le fabricant lance un nouveau pneu à faible résistance au roulement, l'EP150 :   http://www.forum-auto.com/pole-tec [...] 385161.htm
 
Ecopia is Bridgestone’s flagship brand of low rolling resistance tires. In Japan, Ecopia tires were first used on electric-powered cars in 1991, setting the stage for the Ecopia M881 and Ecopia R221 series of tires for trucks and buses, which were released in the replacement market in 2002. Bridgestone launched the Ecopia M812 tire for light trucks in 2005, and then the Ecopia EP100 for passenger cars in April 2008.
 
Bridgestone Corporation also supplies Ecopia EP25 tires as standard equipment for Toyota Motor Corporation’s iQ.
 
Current Ecopia tires employ a compound that applies NanoPro-Tech, Bridgestone’s materials technology, which contributes to a reduction in rolling resistance and better fuel efficiency. NanoPro-Tech (Nanostructure-Oriented Properties Control Technology) draws out the characteristics required to control the microstructure of materials through molecular design.
 
NanoPro-Tech was announced in July 2006, and was first employed in the BLIZZAK REVO2 winter tire for passenger cars which was released in September 2006. It has also been employed in the Ecopia M891 II fuel-efficient tire for trucks and buses. The NanoPro-Tech is now one of Bridgestone’s core technologies.
 
With a conventional tire polymer, the carbon molecules can clump together, causing friction and generating heat, leading to energy loss. In the Ecopia compound, the microstructure of the end-functionalized polymer, which is controlled by NanoPro-Tech, fuses with the carbon molecules. This keeps the carbon molecules dispersed, minimizing energy loss cause by friction between carbon molecules. (See diagram at right).

ECOPIA EP150 has a 15% improved rolling resistance (versus current Bridgestone products in the same dimensions) which makes it, on average, 3% more fuel efficient and achieves a reduction of 3% in CO2 output.
 
The ECOPIA EP150 will be introduced as an integrated replacement and original equipment product during 2010, targeting compacts and mid-sized passenger cars with 14” to 16” rim sizes in 55 to 70 series.
 
In Europe, the ECOPIA brand appeared for the first time in 1999 when the ECOPIA B381 was fitted to the VW 3L Lupo, followed by the Audi A2. In 2008, the Toyota IQ city car left the factory on ECOPIA EP25 tyres.  
 
Bridgestone introduced the range of eco-friendly premium Turanza ER300 ECOPIA tyres in Europe in April 2009. The tyre has also been fitted to some car models as original equipment. With the ECOPIA EP150, Bridgestone will bring the safety and ecology benefits of ECOPIA to small and medium-sized vehicle users.
