Key Points
— Line 17-Gold’s 6.7-kilometre elevated route links São Paulo’s southern zone to Congonhas Airport, with interchange connections to Line 5-Lilás and Line 9-Esmeralda — closing a decades-old transit gap at the cost of R$5.8 billion (approx. US$1.1 billion).
— BYD is now the only company in the world operating as both a dominant electric-vehicle manufacturer and a deployed urban rail supplier in Brazil — its SkyRail system marks the first BYD railway project outside China.
— BYD holds roughly 74% of Brazil’s pure-EV market and is targeting 250,000 vehicle sales and a 10% overall auto market share in 2026, up from 112,800 units in 2025.

The Chinese conglomerate is the only player in Brazil occupying two strategic lanes at once — selling electric cars on the street and running the monorail above it. The inauguration of Line 17-Gold turns that duality from talking point into infrastructure reality.
São Paulo’s long-delayed Line 17-Gold monorail entered preliminary service on 31 March 2026, more than a decade after it was first conceived to ferry football fans to the 2014 FIFA World Cup. The line is operated using BYD’s automated SkyRail technology — and it is the first time the Shenzhen-based company has deployed a railway system anywhere outside China.
The elevated line runs 6.7 kilometres through the city’s southern zone, connecting directly to Congonhas Airport — one of Latin America’s busiest domestic hubs — and integrating with Line 5-Lilás at Campo Belo and Line 9-Esmeralda at Morumbi. Eight stations form the corridor, with each five-car consist carrying up to 616 passengers. The state government is running the line on reduced hours as full commercial service ramps toward the third quarter of 2026, when the system is projected to handle 100,000 daily passengers.
The project’s journey from groundbreaking to ribbon-cutting was anything but smooth. According to InforCapital, the final bill came to approximately R$5.8 billion — nearly three times the original R$2 billion estimate — after contractor disputes, legal proceedings, and pandemic disruptions compounded the delays. BYD entered the picture after a competitive rebid, signing a contract with São Paulo Metro in 2020 to supply 14 four-car train sets, advanced signalling, and supporting infrastructure. The result is the first operational SkyRail system outside Asia.
BYD’s Expanding Brazilian Footprint
The rail inauguration lands at a moment when BYD‘s footprint in Brazil is expanding on every front. The company sold 112,800 vehicles in Brazil in 2025 — making it the first Chinese automotive brand to surpass 100,000 annual sales in the country — and has since raised its 2026 target to 250,000 units, a more than 120% increase, according to CARBA. In February 2026, BYD commanded 78% of Brazil’s pure-EV registrations, with the Dolphin Mini topping the segment at 4,874 units. By March, Rio Times reporting showed BYD ranked fifth among all Brazilian auto brands, with four models in the top 50 and year-on-year growth of nearly 49%.
Underpinning the sales surge is a major manufacturing push. BYD’s Camaçari plant in Bahia — built on the former Ford factory site — is ramping toward an annual capacity of 150,000 units by late 2026, with longer-term plans to scale to 300,000 or more, according to Gasgoo Auto News. The company is also targeting 50% local component sourcing by the end of the year. Separately, a new bus and commercial vehicle factory is in planning, as BYD’s electric bus backlog has already filled 2026 capacity at its Campinas facility.
Strategic Logic and What It Means for São Paulo
The strategic logic behind Line 17-Gold extends well beyond São Paulo. With access to the US market constrained by tariffs, Brazil has become a proof-of-concept market for BYD’s global ambitions — a place where the company can demonstrate both volume manufacturing and infrastructure delivery at scale. A successful SkyRail operation in Latin America’s largest city opens the door to similar bids across the region, where urban rail investment needs are substantial and Chinese financing competitive.
For São Paulo commuters and travellers, the immediate benefit is concrete: an airport link that previously required a bus transfer or a taxi through some of the city’s most congested corridors. When the line reaches full capacity, the 100,000 daily passengers it is designed to carry will represent a meaningful addition to the metro network — and a visible symbol of what Chinese infrastructure investment looks like on Brazilian soil.
