THE MICHELIN PILOT SPORT EV2 PERFORMS IN MEXICO CITY DUST
Round 4 of the 2016/2017 FIA Formula E Championship at Mexico City’s Autodromo Hermanos Rodriguez saw victory go to Lucas di Grassi (Audi Sport Abt Schaeffler). The Brazilian was joined on Saturday’s podium by Frenchman Jean-Eric Vergne (Techeetah) and Briton Sam Bird (DS-Virgin Racing).
As expected, the race took placed in hot sunshine, with high temperatures for the time of year, since Michelin’s technicians recorded 27°C and 47°C for the ambient and track temperatures respectively when the clash kicked off at 4pm local time.
The circuit is rarely used and consequently quite dirty, while the day’s wind blew an additional coating of dust onto the surface. As a result, the drivers spent race day battling with changing grip levels, especially through the baseball stadium portion which is used only by Formula E, as well through the most exposed turns.
The 12-turn 2,092km configuration (five left-handers / 12 right-handers) used the complete oval section (Formula 1 uses only half of it), plus a tighter and twistier run through the baseball stadium grandstands. Like last year, the 40,000 available tickets were all sold out well ahead of race day.
“This year’s Mexico City ePrix certainly lived up to expectations in terms of the show it provided,” remarked Serge Grisin, manager of Michelin’s Formula E programme. “The temperature fluctuations, the quantity of dust on the track and the grip differences due to the surface changes kept the drivers on their toes. Thankfully, we dialled all these situations into the design of the MICHELIN Pilot Sport EV2 to make it as versatile as possible. We knew the championship would throw up a wide variety of conditions and difficulties such as drain covers and painted road markings, and we were also aware that some venues, like Mexico City’s permanent racetrack, would pose other challenges. The portion through the baseball stadium is a unique feature of the season. Today’s exciting race is further evidence that the MICHELIN Pilot Sport EV2 allows the drivers to keep fighting to the very end!”
The MICHELIN Pilot Sport EV2
Michelin is one of the founding forces behind the creation of the FIA Formula E Championship and its objective from the outset has been to deliver a single, durable tyre that is both resistant to wear and capable of racing in wet and dry conditions alike.
The first-generation MICHELIN Pilot Sport EV (EV = Electric Vehicle) was developed especially for Formula E and was the first tyre of its type to be conceived for a world class single-seater racing championship. Thanks to its patterned tread and interior diameter of 18 inches, the MICHELIN Pilot Sport EV bears a striking resemblance to a road tyre, yet it packs several advanced technologies which, after being evaluated in racing, will go on to benefit the drivers of everyday vehicles. Indeed, a number of Michelin road tyres already make use of the lessons that have been learned in Formula E.
The MICHELIN Pilot Sport EV2, which made its debut at the opening round of the 2016/2017 championship, takes energy efficiency in motor racing another step forward. Thanks to the use of new technologies and advanced materials, its rolling resistance is 16 percent lower, with no detriment to its other performance-related characteristics. The front and rear tyres also mark weight savings of 1.1kg and 1.4kg respectively, which equates to a total gain of 5kg per set of four. That in turn means the use of some 2,500kg less raw materials over the course of the season and the equivalent of 250 fewer tyres to be transported around the world. The MICHELIN Pilot Sport EV2 is motor racing’s most efficient tyre.
24/64-18 (front) / 27/68-18 (rear), in accordance with the system used by Michelin Motorsport, i.e. tread band width (cm) / exterior diameter (cm) – rim diameter (inches). This is equivalent to 245/40R18 / 305/40R18 using the road tyre system, i.e. overall tyre width (mm) / aspect ratio (%) / rim diameter (inches). The letter ‘R’ indicates that it is a radial tyre.
