The Volkswagen Polo VI 1.0 TGI (90 Hp) CNG is a subcompact hatchback produced by the German manufacturer Volkswagen from 2017 to 2018. This model represents a significant step in Volkswagen’s efforts to offer alternative fuel vehicles, specifically designed to run on Compressed Natural Gas (CNG) in addition to gasoline. While the Polo has been a mainstay in the European market for decades, the sixth generation saw increased refinement and technology, aiming to compete with rivals like the Ford Fiesta and Opel Corsa. The TGI variant, in particular, was targeted towards environmentally conscious consumers seeking lower running costs and reduced emissions.
Volkswagen Polo VI: A Focus on Efficiency
The Polo VI, launched in 2014, marked a considerable evolution from its predecessor. Built on the Volkswagen MQB A0 platform, it offered improved interior space, enhanced safety features, and a more sophisticated driving experience. The 1.0 TGI variant, powered by a three-cylinder turbocharged engine, was a key part of Volkswagen’s strategy to diversify its powertrain offerings and meet increasingly stringent European emission standards. This model wasn’t widely sold in North America, as the subcompact hatchback segment is less popular than in Europe, and CNG infrastructure is limited in the US.
Engine & Performance
The heart of the Polo VI 1.0 TGI is a 999 cc inline three-cylinder gasoline engine, designated DBYA. This engine utilizes direct fuel injection and is equipped with a turbocharger, allowing it to produce 90 horsepower at 5000 rpm and 160 Nm (118.01 lb.-ft.) of torque between 1800 and 3800 rpm. The engine is designed to run on both gasoline and Compressed Natural Gas (CNG), offering drivers the flexibility to switch between fuels depending on availability and cost. When running on CNG, the engine delivers a reduced output, but significantly lowers emissions. The powertrain is coupled with a five-speed manual transmission, driving the front wheels. Acceleration from 0 to 100 km/h (0-62 mph) takes 11.9 seconds, while the top speed is rated at 183 km/h (113.71 mph). The engine’s power-to-weight ratio is 75.9 Hp/tonne, and the torque-to-weight ratio is 135 Nm/tonne.
Design & Features
The Polo VI 1.0 TGI maintains the classic hatchback body style, offering five seats and five doors. Its design is characterized by clean lines and a relatively understated aesthetic, typical of Volkswagen’s design philosophy. The interior is well-appointed for its class, with a focus on practicality and ergonomics. Key features include ABS (Anti-lock Braking System), electric power steering, and a steering rack and pinion system for responsive handling. The trunk space is a practical 251 liters (8.86 cu. ft.) with the rear seats up, expanding to 1025 liters (36.2 cu. ft.) when folded down. Safety features were a priority in the Polo VI, with a robust chassis and available options like multiple airbags and electronic stability control. The TGI model also benefits from the inherent safety advantages of CNG vehicles, as CNG tanks are typically more resistant to rupture than gasoline tanks.
