Ford Focus ST Emissions Guide

When you’re looking for a new car, whether it’s a brand-new vehicle or a used car, it’s important to be aware of the ongoing running costs to make sure it’s affordable over the long-term. CO2 emissions can have an impact on the ongoing costs of your car so this is a key factor to consider.

This section discusses a range of Ford Focus ST models and their emissions.

CO2's impact on car ownership

Let’s take a look at the impact that vehicular emissions can have on two key elements of running costs for car owners.

Tax costs

The VED (Vehicle Excise Duty) was introduced in April 2020. While this impacted most car owners in some way, the hardest hit are those looking for a brand new vehicle, with newly imposed costs amounting to an average of £300. Costs can vary depending on the make and model of car you choose, so research this thoroughly before deciding on your next car, as running costs on account of VED could push your budget over the edge.

Fuel costs

A petrol engine is invariably cheaper than diesel, irrespective of CO2. However, when it comes to fuel costs in relation to emissions, efficiency is key: g/km, or grams of CO2 released into the atmosphere per kilometre, will have an impact on how hard your car’s engine works. The lower the g/km used, the more efficient and more economical in terms of fuel, your car will be.

Ford Focus ST emissions

Ford Focus ST Petrol models

The Ford Focus ST petrol hatchback model with a 2.3L engine producing 179g/km of CO2 as standard. This also pushes the model into the higher bracket of VED.
The torque on the petrol Ford Focus ST outperforms the diesel at 310lb ft.

Ford Focus ST Diesel models

The diesel Ford Focus ST is slightly better in terms of emissions efficiency and also carries a smaller 2.0L engine. In turn, this means it produces 148g/km, significantly lower than when the Ford Focus ST model is driven at full speed.
This diesel engine produces 295lb ft of torque.

Ford Focus ST EcoBoost and EcoBlue engines

The key difference between the EcoBoost and EcoBlue engines is their fuel type, with the former being a petrol engine and the latter, diesel. Apart from this, both offer exceptional emissions performance, having been designed by Ford to meet Euro 6 emissions standards and ultra-low emissions of 91g/km of CO2. The petrol engine, as mentioned, is also slightly larger than the diesel.

Emissions for newer Ford Focus ST models

The 2020 Ford Focus ST range is more efficient for emissions than the models of previous years. Updates for the 2020 range of Ford Focus ST models include the diesel engine, as well as the “turbocharged” petrol engine, both more efficient on emissions, particularly on the lower PS end of the range. For example, the diesel ST at 120PS emits just 94g/km; the 95PS diesel engine just 91g/km.
The new range of petrol Ford Focus ST models (125PS, 100PS and 80PS) start with emissions from 107g/km, though this is higher as you move up to a 2.3L capacity engine.
However, if you’re looking to keep your emissions low, the smaller end of the new Ford Focus ST range is a great place to start without swaying into electric or hybrid territory.

Older Ford Focus ST models

VED came into place in 2017 so, cars registered before this date are not affected. However, running costs on less-efficient older Ford Focus ST’s can increase fuel and maintenance costs.

Why are new Ford Focus ST CO2 emissions higher than other Ford Focus models?

The simple answer here is performance. The new 2020 Ford Focus ST range offers consistency and fluid power, which can be seen in the torque offered in both the diesel and petrol models.

Is the Ford Focus ST better than other Ford Focus models?

There is no ‘better’ Ford Focus model. The model you choose will be subject to the specifications you’re looking for. But, for emissions, let’s compare the Ford Focus ST to other popular models, such as the Zetec, Titanium and its sister model ST-Line.

Ford Focus ST vs. Ford Focus Zetec

If you’re looking to save on emissions, the Ford Focus Zetec is more efficient at 98g/km, which is worth considering when looking into road taxes and fuel economy.

Ford Focus ST vs. Ford Focus Titanium

The most recent Ford Focus Titanium utilises the EcoBoost engine. The 1.5L engine is economical and green enough to ensure you don’t have to pay road tax at 98g/km of CO2.

Ford Focus ST vs. Ford Focus ST-Line

The Ford Focus ST-Line Edition X, this year's offering, is middle of the range when looking at its g/km output at 134. That makes the ST more favourable choice for those looking for a lower VED rate.
