The EcoBoost 2.3-liter could be replaced with the Atkinson-cycle 2.5.
We were optimistic last December about the next-generation Ford Focus RS, which was rumored would receive an electrified engine with more than 400 horsepower (298 kilowatts). The ever-stricter emission standards in Europe could mean that Ford will have to rethink its strategy regarding the hot hatch.
Initial plans were to use a mild hybrid version of its turbocharged four-cylinder engine of 2.3-liters to power the front wheels, and an electric motor for the rear axle. A new report by Autocar states that a mild-hybrid version of its turbocharged four-cylinder engine will power the front wheels and an electric motor to drive the rear axle. However, this model won’t meet the EU CO2 emission regulations.
An unnamed Ford executive stated that they are still waiting for the engineering team to find a solution to the powertrain problem. This is because of the new CO2 regulations. As “the mild hybrid is not sufficient,” a full hybrid could be the solution.
Even more, the likelihood of the new Focus RS being launched this year is very slim due to the changes in plans. According to Autocar Ford’s revised strategy includes a launch for 2022 or 2023.
Manufacturer will also switch from the 2.3-liter EcoBoost engine in the Focus RS to a modified 2.5-liter Atkinson cycle motor. This new motor is mated with a CVT and all-wheel drive system. This engine is used in the Kuga’s European version. It could be tuned to produce about 300 horsepower (224 kW), with an additional 100 horsepower (74 kW), coming from the electric rear-axle.
