The i20 Blue runs on a 1.4-liter CRDi diesel engine producing 90PS and 220 Nm of torque, matted to a new six-speed manual gearbox – instead of the car’s usual five-speed unit – in which the ratios have been modified in 3rd, 4th and 5th gear. Hyundai’s engineers updated the engine’s electronic software and at the same time improved performance by minimizing driveline friction and utilizing high-performance, low-friction engine oil. Furthermore, the i20 Blue benefits from the addition of a Hyundai-specific ISG Start-Stop system.
In terms of aerodynamics, Hyundai reduced ground clearance by 15mm, added a full-length underfloor cover and performed subtle changes to the design of the grille and bodywork. The package is complemented by a set of Michelin Energy low rolling resistance tires
Together, these changes offer the i20 Blue a reduction of 15 percent in CO2 emissions over the standard car to just 99g/km and an improvement of 15 percent in fuel efficiency consuming 3,75 liters/100km or 63.7 MPG US. As for performance, the i20 blue accelerates from 0 to 100 km/h (62 mph) in around 13 seconds and achieves a top speed of 176km/h or 110 MPH.
When Hyundai says Blue, what the Korean automaker actually means is green as the i20 Blue concept study that will debut in
