Hyundai has revealed details for its third-generation i20, which launches next spring with all-new styling, mild hybrids and revised trim levels.

The third-gen i20 is longer, lower and wider than before and introduces a new mild hybrid engine

Priced from £18,595, the latest incarnation of the supermini was revealed earlier this year and arrives in the UK next spring.

It’s Hyundai’s first car in Europe to use its new ‘Sensuous Sportiness’ design language that will be rolled out across other models. The i20 is also longer, lower and wider than before, with a 10mm longer wheelbase, enabling a 25-litre increase in boot space to 351 litres overall.

The engine line-up now includes a 1.0-litre turbocharged GDi engine with 48V mild hybrid powertrain – the first mild hybrid to launch in the i20 line-up and the sole engine in the UK line-up. It offers 100hp of power and 172Nm torque with CO2 emissions from 115g/km. Fuel economy hasn’t been announced yet. It’s married up with a six-speed automated manual transmission as standard, with an optional seven-speed dual-clutch version also available.

More sporty performance will be offered when the i20 N Line and i20N join the range, the latter offering 204hp from its 1.6-litre turbocharged GDi engine with a 0-62mph time of 6.7 seconds.

Trims for the standard i20 have also been streamlined, as with the i10 city car earlier this year. The three-grade range ditches the former S Connect and now starts with the SE Connect, rising to the Premium and a new Ultimate trim, focused on offering higher equipment. Hyundai says the enhanced specification across the new i20 range has ensured a significant increase in residual values, which are up by 4.6 percentage points over the previous i20.

Entry-level equipment includes 16-inch alloy wheels, LED daytime running lights and halogen projector headlamps with static cornering function. Interior equipment brings an 8-inch touchscreen display audio with subscription-free Apple CarPlay and Android Auto, 10.25-inch instrument cluster with customisable functions, manual air con, cruise control with speed limiter function and rear parking sensors with rear view camera and electrically adjustable and heated wing mirrors.

Hyundai’s SmartSense safety package is also standard, offering forward collision alert, driver attention alert, intelligent speed limit warning, high beam assist and lane keep assist.

The i20 Premium is available from £20,795 and adds in a range of features, including a larger 10.25-inch touchscreen navigation, as well as Hyundai’s Bluelink telematics system with a free five-year subscription. The premium also gets lane follow assist added to the SmartSense safety package.

The new Ultimate trim is available from £22,095 and includes a two-tone roof as standard and grey interior trim. Additional features include smart key with keyless entry and engine start/stop button, a wireless charging pad for compatible devices, blind-spot collision warning and forward collision assist with cyclist detection.

The i20 Ultimate also introduces a Bose Premium Sound System; a first for a Hyundai.

All new i20 models also come with Hyundai’s usual five-year unlimited mileage warranty, along with its roadside assistance package, five-year annual health check, and 12-year anti-corrosion warranty.
