Simona de Silvestro

On 21 May, using her backup car, she qualified 24th for the race with a four-lap average of 224.392 mph.

After a crash at the Milwaukee Mile during qualifying, de Silvestro was cleared to drive in the race, but withdrew after experiencing dizziness and impaired vision.

At the next race, in Iowa, she was not cleared to compete, due to continuing dizziness.

De Silvestro missed round 13 of the season at Sonoma, after being refused entry to the United States.

De Silvestro said she did not know why she was turned away.

She finished 24th overall in the series standings.

Simona de Silvestro (born 1 September 1988) is a Swiss-Italian racing driver, who is currently employed by Porsche as a factory driver.

She raced for Newman Wachs Racing's Nuclear Clean Air Energy-Entergy team in the Atlantic Championship in 2008 and for Team Stargate Worlds in 2009.

She won the Atlantic race at the 2008 Grand Prix of Long Beach, making her the second woman to win in that series – after Katherine Legge – and providing NWR with its first win.

She won four times during the 2009 season and led in points for most of the season, but ultimately finished third in the standings after retiring on the first lap during the season finale at Mazda Raceway Laguna Seca.

De Silvestro participated in an IndyCar Series test over 8–9 December 2009 at Sebring International Raceway, a joint effort between HVM Racing and Team Stargate Worlds.

De Silvestro competed full-time in the IndyCar Series for HVM Racing for the 2010 season.

On 22 May 2010, she qualified in the 22nd position for the 2010 Indianapolis 500.

She suffered a burned right hand after a fiery crash at the Firestone 550 at Texas Motor Speedway on 5 June 2010.

Her team strongly criticized IndyCar Series safety officials for their response to that accident.

For the season, de Silvestro started 17 races, finished ten, and recorded two top-10 finishes, with a best finish of eighth at Mid-Ohio.

The 2011 season began with fourth- and ninth-place finishes at St. Petersburg and Barber; however the next race, at Long Beach, was not as successful: she started 18th and finished 20th.

At the next race, the São Paulo Indy 300, an accident between her and Hélio Castroneves put her nine laps down, after the race was postponed to the next morning due to severe rain conditions.

She received second degree burns on her right hand and superficial burns on her left hand in a crash during practice for the 2011 Indianapolis 500 on 19 May.

The crash, which sent her car sailing into the catch fence before flipping and landing on its left tires, was caused by a mechanical failure in the left rear of her No. 78 Dallara-Honda.

She finished 20th overall in the 2011 series standings.

De Silvestro returned to HVM Racing for the 2012 IndyCar Series season, piloting the No. 78 Nuclear Clean Air Energy sponsored Dallara-Lotus.

The entry was one of five cars to start the season powered by the new Lotus engine.

The Lotus proved to be significantly underpowered compared to the Chevrolet and Honda engines used by the rest of the field.

By the end of May, all entrants other than de Silvestro's No. 78 had abandoned the Lotus powerplant and switched to either Chevy or Honda.

De Silvestro was saddled for the entire season with the inferior Lotus.

The underpowered engine made it impossible for de Silvestro to be competitive, resulting in consistently poor qualifying and race results.

On several occasions the car was black flagged for failing to maintain the minimum safe speed, including the 2012 Indianapolis 500.

For the season, de Silvestro qualified for all 15 races on the schedule, started 14, and finished 6.

On 30 October 2012, de Silvestro signed on with KV Racing Technology for the 2013 IndyCar Series season, driving the No. 78 Dallara-Chevrolet with sponsorship from Nuclear Clean Air Energy.

She started 13th and finished 20th, nine laps down, but recorded the fastest lap of the race.

De Silvestro joined veteran driver Tony Kanaan to make KV Racing Technology a two-car team for the 2013 season.

On 5 October 2013 at the Grand Prix of Houston, de Silvestro finished second in the first race for her first podium finish, joining Danica Patrick and Sarah Fisher as the only women in IndyCar history to record a podium finish.

She finished the race in 14th position, and earned Indianapolis 500 Rookie of the Year honors.

Her best finish was 14th at Detroit and Iowa.

She has previously driven for Amlin Andretti in the 2015/16 season of the FIA Formula E Championship as well as several years competing in the IndyCar Series.

Her nicknames are the "Iron Maiden" and "Swiss Miss".

On 2 April 2015, de Silvestro announced she would drive the Andretti Autosport No. 29 Honda in the 2015 IndyCar Series season in an attempt to make the Indianapolis 500.

De Silvestro finished fourth in the second race of the season, the Indy Grand Prix of Louisiana.

She finished 19th overall in the series standings and was runner-up to Alex Lloyd for rookie of the year honors.
