The model will sit in Kia's "EcoDynamics" range of fuel-saving vehicles, and has 11% less CO2 emissions than the current model – 98g/km compared with 110g/km for the current cleanest cee'd.

The EcoDynamics cee'd is powered by Kia's new 1.6-litre diesel engine, which uses the latest generation common rail diesel injection system and is fitted with a Variable Geometry Turbocharger. The unit produces 90PS at 4,000rpm and maximum torque of 235Nm across a wide rev band, from 1,900 to 2,750rpm.

In the EcoDynamics cee'd, the engine features improved engine mapping and fuel injection strategy with new software and is fitted with a variable water pump which absorbs less power, a high efficiency alternator with power-saving management system and a Diesel Particulate Filter. The model also features a revised top gear ratio for the six-speed manual transmission.

In addition, the EcoDynamics cee'd is equipped with a range of fuel-saving features including Kia's fuel-stretching Intelligent Stop and Go system, which automatically switches off and then restarts the engine in congested city driving, and now features optimised system logic. There's also a gear-shift up/down indicator, dubbed the Eco Driving Guide.

Other revisions to the model include lowered suspension, the use of a smooth under-floor with airflow deflectors ahead of each tyre and a rear spoiler, plus low rolling resistance tyres.

On-sale dates for the revised EcoDynamics cee'd have not yet been confirmed.
