The vehicle’s lightweight construction, with a curb weight of just 2403.04 lbs (1090 kg), contributed to an excellent weight-to-power ratio of 10.4 kg/Hp, or 96.3 Hp/tonne, further aiding its lively character.

Fuel Economy and Environmental Footprint

Fuel efficiency was a major selling point for this model. The combined NEDC (New European Driving Cycle) fuel consumption was an impressive 5.3 l/100 km, which translates to approximately 44.4 US mpg. Urban driving yielded 33.6 US mpg (7 l/100 km), while extra-urban conditions saw consumption drop to an outstanding 53.5 US mpg (4.4 l/100 km). With CO2 emissions rated at 124 g/km, the Ibiza IV ST 1.2 TSI met Euro 5 emission standards, reflecting its environmentally conscious design for the era. The 11.89 US gallon (45 liter) fuel tank provided a substantial range between fill-ups.

Design and Features
