The Daihatsu Boon (Japanese: ダイハツ・ブーン, Daihatsu Būn) is a subcompact car produced by Japanese automaker Daihatsu since 2004, and also sold under Toyota brand as the Toyota Passo (Japanese: トヨタ・パッソ, Toyota Passo). The Passo was once sold at Toyota Corolla Store Japanese dealerships until it was consolidated with other Toyota dealers in 2020.

Outside Japan, the first and second-generation Boon is sold as the second and third-generation Sirion. The first-generation Sirion was sold as the Storia in Japan.

According to Daihatsu, the name "Boon" is derived from the English word boon, and also inspired by the sound that Japanese children make when imitating the sound of a car,[1] while the name "Passo" is Italian for "step". According to Toyota, the name conjures up the image of a casual and approachable car.[2]

The development for the first-generation Boon was led by Toyota chief engineer Tetsuya Tada.[3] For the Japanese domestic market, the Boon were available with 996 cc and 1.3 L engines. The major difference between the Japanese Boon and Sirion are automatic version where the gear-changing located beside the steering on the dashboard and the handbrake below the steering. Both the Japanese Boon and European Sirion were offered in both front-wheel drive and four-wheel drive versions. A 936 cc turbocharged version with four-wheel drive was also available, known as the Boon X4.

The Boon was designed for European tastes and the model took on a larger and stockier frame. It weighs about 940 kg (2,072 lb). With the back seats down, its luggage capacity increases from 225 L (8 cu ft) to 630 L (22 cu ft).

On 25 May 2005, Malaysian automaker Perodua launched a variant of the Boon known as the Perodua Myvi. Sporting a few cosmetic differences, the Myvi became Perodua's best-selling car in Malaysia for 2006, 2007, 2008 and 2009.

On 25 December 2006, the Boon was restyled. This version was exported to Europe as the Sirion in 2007.

In 2007, Daihatsu launched the Sirion in Indonesia using the facility and parts from the Myvi.[4]

The Subaru Justy was unveiled at the 2007 Frankfurt Motor Show using the Boon model. It is positioned as an entry-level model in Subaru’s lineup.[citation needed]

In April 2013, Toyota New Zealand announced its decision to stop selling the second-generation Sirion, still on sale, stating it was unable to secure Daihatsu products that comply with future regulatory standards for New Zealand.

The second-generation Sirion was discontinued in South Africa in April 2015, when Daihatsu left the South African market.[citation needed]

The Boon Luminas and Passo Sette were discontinued in early 2012 due to poor sales. The Malaysian variant was launched in the country as the Perodua Alza.

The third-generation Boon and Passo were unveiled in Japan on 12 April 2016. Both received the first update on 10 October 2018, along with the introduction of "Style" variant for the Boon. The Passo has an improved collision avoidance support system (Smart Assist III) which can grasp various information such as pedestrians, vehicles, preceding and oncoming vehicles, and obstacles and then activate various driver assistance systems such as alerting the driver or switching between low and high beams.[11]

The third-generation Boon is currently the only model that does not share any mechanical/visual components with the third-generation Myvi/fourth-generation Sirion.
