Frankfurt 2007 brings us another concept based on the new cee’d family of cars – the Kia eco_cee’d concept. It is based on the 3-door pro_cee’d hatchback and is powered by a 1.6 litre CRDi turbodiesel engine. Through minimal Volkswagen BlueMotion-style modifications to the base vehicle, CO2 emissions drops to 104g/km and fuel consumption is now just 3.9 litres for every 100km travelled.
The 1.6 litre CRDi engine power output remains at the stock 115 PS output levels, and the brake system remains unchanged. This improved emissions and fuel consumption level is thanks to a reduction of drag coefficient to 0.29 cD from 0.33 Cd. This is achieved via lowering the suspension by 15mm, fitting under-floor coverings to the front, middle and rear of the vehicle, adopting plastic wheel arch linings with spoiler lips to smooth airflow around the wheels, a special front grille designed for low-drag, ultra-low rolling resistance Michelin Energy 205/50R17 tyres, and special alloy wheels designed to generate minimum disturbance to airflow along the sides of the car. The car has also been lightened with the use of a tyre repair kit in place of a spare wheel.
The powertrain is also fitted with Kia’s Idle Stop & Go system, which uses Smart Battery Power Management jointly developed with automotive electronics specialist Bosch. This system recharges the battery automatically during deceleration and switches the engine if the ECU determines that the car is in a stopped and idle status with conditions that are appropriate to switch the engine off. When first gear of the 6-speed manual gearbox is selected, the engine is restarted instantly.
The new 6-speed manual is an improvement over the standard 1.6 litre CRDi pro_cee’d’s 5-speed unit, with higher ratios for the last 3 gears to reduce engine RPM while cruising, taking advantage of the turbodiesel’s good low end torque. The ECU also displays the optimum gear to be in on a shift indicator fitted in the instrument cluster.
