- Engine line-up tuned to optimise day-to-day driveability
- European powerplants provide greater maximum and low-end torque
- Turbocharged 1.0 T-GDi engine joins 1.2- and 1.4-litre petrol units
- Five and six-speed manual and four-speed automatic transmissions
- All engines are Euro 6 compliant
- The i20 is available with a choice of three petrol engines – the 1.0 and 1.2 units from the ‘Kappa’ petrol engine family and the ‘Gamma’ 1.4.
The highlight of the range is the 1.0 T-GDi turbocharged petrol engine - available with 100ps or 120ps - which joins the proven powerplants carried over from the previous-generation model. Each features a number of improvements to enhance driveability and ensure compliance with new Euro 6 emission regulations.
Hyundai's European engineering team, based at the Technical Centre in Rüsselsheim, Germany, focused on developing powertrains to better suit the demands of the region's buyers. The 1.0 T-GDi is just one of those resulting powertrains, with excellent performance, smooth, quiet running and impressive fuel economy
Hyundai engineers also tuned every other unit in the range to deliver more maximum and low-end (2000 rpm) torque, enabling a more accessible and responsive driving experience day-to-day. As a result, for example, the i20 can accelerate between 50 and 75 mph faster than before.
The much-praised 1.2-litre 'Kappa' four-cylinder is available in two different power outputs dependant on trim specification. The low power (75 ps) offers 58.9 mpg (combined cycle) and 112 g/km. The higher power (84 p)s version returns 55.4 mpg on the combined cycle and emissions of 119 g/km.
The Kappa 1.0-litre three-cylinder T-GDi 100ps unit is a 998 cc engine, turbocharged and downsized to ensure responsive performance with ultra-low emissions. This engine produces just 99g/km of CO2, and is capable of 65.7mpg. The i20 Active 1.0-litre 100PS figures differ slightly with CO2 of 110g/km and a combined fuel economy of 58.9mpg. In i20 Premium models and above, customers can also opt for a higher-powered 1.0 T-GDi engine producing 120ps. Fitted with a six-speed manual gearbox, it's the fastest and most exciting powertrain in the i20 line-up and delivers impressive combined fuel economy of 58.9mpg.
Customers looking to buy an i20 fitted with an automatic gearbox, can opt for the Gamma 1.4-litre engine, which at only 87 kg is nearly 14kg lighter than the engine it replaced.
Outstanding features of the Kappa engine's modern architecture include dual overhead camshaft (DOHC), dual continuously variable valve timing (CVVT), a very stiff cast aluminium block with cast iron liners, aluminium cylinder head, lighter connecting rods and maintenance-free long-life timing chain.
Both the five-and six-speed manual transmissions fitted to the i20 have been extensively tested to deliver a smoother, quieter and more tactile shift, in keeping with the other quality enhancements made for the model. The transmissions now feature multi-cone synchroniser rings on the first two ratios, a carbon-coated synchroniser ring on ratio three, and an anti-vibration mechanism fitted to the reverse gear to prevent 'grinding' noise and feel. Shift accuracy and snap-in feel has been improved with the addition of a guide plate inserted in the control shaft coupling.
