What does 300TGI mean?
2 Answers
300TGI is the code name for a vehicle engine. This code does not represent the engine model but refers to a model launched by SAIC Motor, specifically the Roewe RX5 MAX. It corresponds to a 1.5-liter turbocharged four-cylinder engine with a maximum horsepower of 173, a maximum power output of 127 kW, and a maximum torque of 275 Nm. Below is an extended introduction: Model Introduction: The vehicle dimensions are 4647 mm in length, 1891 mm in width, 1725 mm in height, and 2760 mm in wheelbase. The model is a 5-door, 5-seat SUV version with a fuel tank capacity of 55 liters. The vehicle is positioned as a compact SUV and is equipped with either a 1.5-liter or 2.0-liter turbocharged engine. It uses a 6-speed automatic, 6-speed dual-clutch, or 6-speed manual transmission.
Nowadays, many car tails are marked with alphanumeric combinations like 300TGI, and I've studied this naming system. '300' indicates that the engine's maximum torque is around 300 N·m, with the actual range likely being 280-320. 'T' stands for turbocharging technology, which uses exhaust gases to drive a turbine for forced induction, allowing a small 1.5L engine to deliver power comparable to a 2.4L naturally aspirated engine. 'G' refers to gasoline fuel, and 'I' represents direct injection technology. Taking a certain brand's 1.5T engine as an example, although the displacement is modest, the turbocharger enables it to output 300 N·m of torque, delivering noticeably stronger acceleration from a stoplight compared to a typical 2.0L naturally aspirated car.
