The Ford Focus ST is a performance-oriented hatchback that has been captivating enthusiasts for years. Available with both diesel and petrol engine options, the ST offers a unique blend of power, handling, and practicality. In this comprehensive comparison, we delve into the key differences between the diesel and petrol variants of the Ford Focus ST to help you make an informed decision about which one is right for your needs.
Power and Performance
At the heart of the Ford Focus ST diesel lies a 2.0-liter EcoBlue turbocharged four-cylinder engine that produces 185 horsepower and 310 lb-ft of torque. The petrol-powered ST, on the other hand, features a 2.3-liter EcoBoost turbocharged four-cylinder engine that generates 280 horsepower and 310 lb-ft of torque.
While the petrol ST boasts a significant advantage in horsepower, the diesel ST delivers impressive torque at lower RPMs, resulting in better acceleration from a standstill. However, the petrol ST’s higher horsepower output provides a more exhilarating driving experience at higher speeds.
Fuel Economy and Emissions
Diesel engines are traditionally known for their fuel efficiency, and the Ford Focus ST diesel is no exception. With a combined fuel economy rating of up to 47 mpg, the diesel ST is significantly more economical than its petrol counterpart, which has a combined fuel economy rating of around 35 mpg.
Moreover, diesel engines produce lower CO2 emissions compared to petrol engines. The Ford Focus ST diesel emits approximately 115 g/km of CO2, while the petrol ST emits around 155 g/km. This makes the diesel ST a more environmentally friendly option.
Handling and Dynamics
Both the Ford Focus ST diesel and petrol offer exceptional handling and driving dynamics. They feature a sophisticated suspension system, quick steering, and a limited-slip differential that enhances cornering performance.
However, the petrol ST‘s lighter weight (by approximately 100 pounds) provides it with a slight edge in terms of agility and responsiveness. The petrol ST also benefits from a more aggressive suspension setup that results in flatter handling and reduced body roll.
Comfort and Refinement
The Ford Focus ST diesel is generally considered to be more refined than the petrol ST. The diesel engine produces less noise and vibration, especially at idle and low RPMs. The diesel ST also features better sound insulation, which helps to reduce road and wind noise in the cabin.
On the other hand, the petrol ST offers a more engaging driving experience with its throaty exhaust note and responsive throttle. The petrol ST’s stiffer suspension setup may compromise ride comfort slightly, but it provides a more direct and connected driving feel.
Technology and Features
The Ford Focus ST comes equipped with a range of advanced technology and features. Both the diesel and petrol variants feature a 8-inch touchscreen infotainment system, navigation, and a premium sound system.
The diesel ST offers a few additional features, including a heated steering wheel, heated front seats, and a rearview camera. The petrol ST, on the other hand, comes standard with Recaro sport seats that provide excellent support and comfort.
Price and Value
The Ford Focus ST diesel typically has a lower starting price than the petrol ST. However, the higher fuel economy and lower CO2 emissions of the diesel ST can offset the initial price difference over time.
The petrol ST offers more power and performance, but it comes at a premium. Ultimately, the best value for you will depend on your individual needs and preferences.
Which Ford Focus ST is Right for You?
The choice between the Ford Focus ST diesel and petrol depends on your priorities and driving style. If you prioritize fuel economy, refinement, and lower emissions, the diesel ST is an excellent choice. However, if you crave more power, performance, and a more engaging driving experience, the petrol ST is the way to go.
Takeaways: A Balanced Decision
Both the Ford Focus ST diesel and petrol offer unique advantages and drawbacks. The diesel ST provides impressive fuel economy, refinement, and lower emissions, while the petrol ST delivers exhilarating performance and engaging driving dynamics. By carefully weighing your needs and preferences, you can make an informed decision about which Ford Focus ST is right for you.
