Alexandra Asmasoebrata (Allida Alexandra)

Alexandra Asmasoebrata, also known as Allida Alexandra or Andra, is an Indonesian driver who competed up to international Formula Renault level. 

After four or so years of karting, she first stepped up to single-seater racing aged 16, taking part in the 2004 Formula BMW Scholarship shooutout in Spain. She was not among the winners and did not make her competitive debut until the following year. Her first races were in 2005, when she did some rounds of the China Formula Campus series, winning her class.

She first drove in the Asian Formula Renault Challenge in 2006, aged eighteen. She was 24th overall after participating in seven races. The best of these was her last one at Shanghai, where she was ninth overall. The following year, she did six races, starting at Zhuhai, Sepang and Beijing. Her best finish was a fourteenth place at Beijing.

In 2008, she reappeared in AFR. She was twelfth this time, with a best finish of fifth at Zhuhai, in her first race of the season. This was one of four top-ten finishes she had that year, the others being an eighth and two ninths at Shanghai and Sepang.

For most of her career, she combined Formula Renault and karting. The following year, she was third in the 

A shorter season in 2009 meant that eighth was her best finish, also at Zhuhai, a feat she bettered in 2010 with a fourth place at Zhuhai. She was eighth in the championship. By then, the series was being held entirely in China. 

In 2011, she drove in both the Asian Formula Renault Challenge and Formula Pilota in China. It was her best season yet; she was third in Formula Renault with five podium finishes, four thirds and one second, at her favoured Zhuhai. 

Unfortunately, she only entered four races in 2012: three rounds of Asian Formula Renault. Her finishes were two sevenths, and two DNFs. 

She bounced back in 2013, taking part in six Asian Formula Renault races and earning two thirds and four fourths. She was fourth overall. 

In 2014, she was set to race in Asia Formula Renault again, but does not appear to have competed. A long lay-off followed, where she had three children among other things. She returned to the tracks in 2026, racing in the Mandalika Kartini race, a women's championship held at the Mandalika circuit in Indonesia. There were seven other entrants in Krida Agyas. Alexandra was third.

Alexandra is the daughter of former Indonesian racing driver and politician, Alex Asmasoebrata. It was him who first took her karting and she is open about how this helped her during her own career.

Diana Rosario

Diana Rosario is a racer from Macau who is best-known for her efforts in single-seaters, and later, sportscars.

As there is only one circuit in her home country, which is a street circuit and therefore not usually in use, she had to cross the border to race, in China and further afield in Asia. 

Her first time in a single-seater was in 2004, when she was 20. She took part in the Formula Racing Development training school following several successful years of karting in Macau. In order to gain more experience, she worked at kart circuits after school. Her career almost came to a premature end in 2000 when a 16-year-old Diana broke her collarbone during karting practice, but she later credited the experience with helping her mature as a driver.

In the early part of her career, she concentrated on single-seaters, sticking to championships promoted by FRD. She entered the 2005 Formula Campus Challenge in China, driving for the Perfect Beauty team. After eight races, she was unplaced. A few years later, she would return to the Ford-powered series, finishing second in 2009 and winning the title in 2009. Her 2009 victory was by 38 points over her nearest rival, La Wai Lung of Hong Kong.

She competed sporadically in Asian Formula Renault from 2008, with a best finish of fifth overall in 2011. The championship was run in China and her best result came at Zhuhai, where she was fourth.

At the same time, she was developing a parallel career in sportscars. She competed at the prestigious Macau Guia race meeting in 2010 and was 22nd in the Macau GT Cup, driving a Ferrari F360. Presumably in the same car, she took on the Zhuhai rounds of the Asian GT Series, finishing second and third. Her second run in the Macau GT Cup in 2011 gave her an 18th place, competing against Chinese driver Rose Tan Ying. Eduardo Mortara was the winner.

She committed fully to sportscars in 2012. The GT Cup was not her best event and she was 25th in a Ferrari F430, but her two races in the Asian GT Series were enough for eighth in the championship. Further afield, she took the Ferrari to Sepang for a round of the Malaysian Super Series, finishing eleventh in the GT class.

In 2013, she was linked with a drive in the Asian Le Mans series, but does not appear to have competed. 

Later, in 2018, she made a comeback in the Asian Blancpain GT Series, driving a Mercedes GT4 for Craft Bamboo Racing. Her best finish was fourth at Ningbo, alongside team-mate Naomi Ran Zhang. She had shared the car with James Tang earlier in the season.

She has not raced since then.
