Škoda Auto Presenting Second-Generation Greenline Models at Paris Show; Start-Stop, Braking Energy Regeneration
27 September 2010
Škoda Auto, a member of the Volkswagen Group, is presenting a range of second-generation GreenLine cars at the 2010 Paris International Motor Show; the second-generation GreenLine models incorporate technologies such as a start-stop system and braking energy recuperation.
The 1.6 TDI CR 105 bhp (Octavia, Yeti and Superb) and 1.2 TDI CR 75 bhp (Fabia and Roomster) engines are equipped with diesel particulate filters (DPF).
Design measures in second-generation GreenLine versions deliver enhanced fuel consumption and a reduction in CO2 emissions. The Fabia GreenLine and the Fabia Estate GreenLine have combined fuel consumption of 3.4 L/100km (69 mpg US), with CO2 emissions of 89 g/km. The Roomster, a compact MPV, has a consumption of 4.2 L/100km (56 mpg US), with CO2 emissions of 109 g/km.
The Škoda Octavia GreenLine will be available as both a hatchback and an estate. The hatchback version has combined fuel consumption of 3.8 L/100km (62 mpg US) and CO2 emissions of 99 g/km; while the Estate achieves 4.2 L/100km (56 mpg US) with CO2 emissions at 109 g/km.
The Yeti GreenLine crossover vehicle has combined fuel consumption of 4.6 L/100km (61.4 mpg US) with 119 g/km of CO2. GreenLine versions are also offered on the range-topping Škoda Superb and Superb Estate. Both versions have combined fuel consumption of 4.4 L/100km, with CO2 emissions of 114 g/km.
These modifications have already been available for VW Golf, Polo and other models since (roughly) this spring.
I have been considering the Golf Estate as candidate for my next car but the Octavia Estate might also be an option. It is a pity though, that neither of them could break the 100 g/km CO2 barrier. Yesterday, I did a test drive of the corresponding VW Golf. The power of 105 hp does not sound impressive but the torque of 250 Nm is quite adequate. A naturally aspirated gasoline engine to equal this would have to be about 2.5 liters in size and then we are talking about a (small) V6 engine. However, for highway overtaking, the mentioned horses are rather small.

It is difficult to understand that CO2 missions are not much lower with the very low fuel consumption reached. The ICE used must have some design or tweaking problems.

Diesel just has more carbon per litre than petrol: 4l/100km of diesel burned completely corresponds to 105g/km of CO2. Lower CO2 relative to fuel consumption would indicate incomplete combustion and so a design problem.

Combustion in a diesel engine is more complete than in an otto engine. Proof of that is that unburned hycrocarbon and CO emissions are lower for diesel cars. The explanation to the observation is that diesel fuel has a higher density than gasoline. Carbon content per MJ or kg of fuel is almost exactly the same for both fuels but per liter, diesel fuel contain more carbon. This is the simple explanation...
Most important is CO2 emissions are lower for diesel cars compared to gasoline cars. Moreover, less carbon is emitted in production and distribution of diesel fuel.
