Vauxhall and its parent company General Motors are in the process of rolling out 13 new engines between now and 2016, as the manufacturer looks to improve the refinement and emission levels of its powertrain line-up.
One new unit has already debuted in the new Cascada convertible and more petrol and diesel engines ranging from 1.0-litre to 2.5-litres are on the way as Vauxhall Opel works to address criticism of current engines.
Engineers have been working on making big improvements in issues such as noise, vibration and harshness as well as fuel economy and emissions.
The new engines will cut the brands CO2 emissions by 27 per cent by 2020 according to Mike Ableson, Vice President, engineering, at GM Europe.
He added: "That equates to 1 million tonnes less of CO2 in that time period. The new engines, along with brand new manual and automatic transmissions that we are also rolling out are part of our Drive 2022, 10-year action plan.
"We have taken on board a lot of constructive criticism from customers in terms of our engines and transmissions and we have been working on these new products for the past five years."
As part of this, the development of diesel engines has been taken in-house by GM after many years of collaboration with other carmakers including Isuzu and Fiat.
With the new engines being rolled out over the next three years, Ableson said the more recent strategic alliance with PSA Peugeot Citroen of France will play an important role. "Anytime you have that sort of technical exchange you are going to learn things," he added.
It is not just new engines which will help the carmaker cut emissions, there will also be new manual and automatic gearboxes for low-, mid- and high torque engines. Also under development are new continuously variable and dual clutch transmissions, although details are yet to be revealed.
