With the rising cost of fuel and the increasing negative effects of CO2 emissions in the climate change arena, governments around the world are putting pressure on motor manufacturers to reduce fuel consumption and therefore the CO2 emissions of their engines.
In fact they have been mandated to decrease their CO2 emissions to a maximum of 95 grams per km by 2020, where presently the maximum limit is 130 grams per km.
Hence motor manufacturers are tweaking their engines and bringing out vehicles with smaller turbocharged “Eco” engines.
Opel is ahead of the curve and new vehicles are being launched with 1.0 Turbo and 1.4 Turbo Ecotec engines.
The Opel Adam, Opel Mokka, Opel Corsa and Opel Astra models all come out with these engines.
Fewer cylinders mean less friction, lower revs mean less friction. Smaller engines are also lighter. This all means that the vehicles are more fuel efficient and produce lower CO2 emissions.
In order to keep the power levels up with the larger, naturally aspirated engines, turbo chargers have been added to produce greater torque at low speeds. Turbos also improve fuel consumption at lower speeds, which is perfect for in city driving.
The old problem of turbo lag is no longer the case with these new engines, the manufacturers have researched and developed engines that operate smoothly and powerfully, there is no more turbo lag.
It is projected that 90% of US passenger and light commercial vehicles (bakkies), will all have small turbo charged engines within a decade. With manufacturers like Opel bringing in the most modern vehicles into our country, South Africa will not be far behind.
Buy an Opel with a smaller turbo charged engine and you will be buying a fuel efficient, cost effective vehicle that doesn’t harm the environment as much as before.
