Powertrain and Driving Dynamics
Turbocharged Four-Cylinder Performance
The 2021 Mustang’s turbocharged engine comes from the Focus RS. This four-cylinder engine is quick and responsive, almost matching the real-world speed of the GT model. While the GT’s naturally aspirated V8 will still pull ahead at high speeds, the turbo unit delivers impressive acceleration and feels eager when pushed. It stands out for its efficiency, often returning over 20 mpg in city driving and up to 25–26 mpg on the highway. Compared to the V8, this engine offers better fuel economy while still providing spirited performance.
Key Points:
- Turbocharged Focus RS engine
- Strong mid-range power, nearly as fast as the GT in daily driving
- Fuel-efficient for a sports car (see table below)
| Engine Type | City (mpg) | Highway (mpg) |
|---|---|---|
| 2.3L Turbo (I4) | 20+ | 25–26 |
| 5.0L V8 (GT) | ~16 | 22–23 |
10-Speed Automatic Gearbox
The available 10-speed automatic transmission pairs well with the turbo engine. Around town, shifts are smooth and predictable. In Sport mode, it becomes more aggressive and responsive, making driving more exciting. Paddle shifters work quickly, allowing the driver to manually shift gears and even bounce off the rev limiter. This automatic transmission handles both relaxed and spirited driving with ease.
Highlights:
- Smooth, quick shifts in normal driving
- More aggressive behavior in Sport mode
- Paddle shifters are responsive and easy to use
Manual Shifting Feel
Manual transmission fans may be disappointed with the standard six-speed found in the Ecoboost and other regular Mustangs. The clutch pedal often feels vague, making it difficult to judge engagement points. This feedback issue can make spirited driving less enjoyable. In contrast, the Tremec six-speed manual available in other models like the Camaro, Challenger, and Mach 1 Mustang delivers a more precise and satisfying shifting experience. Those seeking the best manual feel in a Mustang should look for models with the Tremec gearbox.
- Standard six-speed manual has an unclear clutch feel
- Tremec six-speed manuals in select models are much more precise
- Other brands offer manuals with better feedback and control
On-Road Performance
Everyday Speed and Pickup
The 2021 EcoBoost High Performance Mustang uses a Focus RS engine paired with a 10-speed automatic transmission. Around town, the transmission shifts smoothly and doesn’t feel rough. When pressing the car harder, it responds quickly and feels nearly as fast as a GT Mustang in regular driving situations. On the highway, the GT still has an advantage at higher speeds because of its extra power. The EcoBoost model is still quick and offers good gas mileage, often getting over 20 mpg in the city and around 25–26 mpg on the highway.
Response in Sport Driving Settings
Switching to sport mode improves the Mustang’s responsiveness. The transmission and paddle shifters react sharply, letting drivers push the car more aggressively. The engine feels lively and likes to be revved. Drivers notice a clear difference in how the car acts when sport mode is on, especially when using the manual shifting option with the paddles.
Sport Mode Features:
| Feature | Experience |
|---|---|
| Transmission Response | Fast and smooth shifts |
| Paddle Shifter Input | Quick to react |
| Engine Feel | Eager and willing |
Steering Feel and Driver Feedback
The Mustang offers a balanced ride for daily driving, but some drivers feel the steering and chassis could communicate better at the limits. There can be an unclear feeling from the front and rear when driving aggressively, making it hard to judge exactly what the car is doing. This lack of feedback can make the car less forgiving, especially in wet conditions.
Newer models have shown improvements, as Ford continues to adjust the handling each year. The Mustang is still capable, and many owners upgrade suspension parts for better response. Its competitors, like the Camaro and Challenger, offer clearer feedback to the driver, but the Mustang remains enjoyable for regular driving.
Powertrain Choices and Proven Performance
5.0L V8 Coyote Pros and Cons
The 5.0L V8 engine is known for its strong sound and lively performance. Many people think it is one of the best-sounding options for the price. It has a reputation for being reliable, especially compared to some other high-power engines. While it may not have the most horsepower in its class, it still delivers fast acceleration and a classic muscle car feeling.
Turbocharged Four-Cylinder with RS Origins
The turbocharged four-cylinder engine comes from the Focus RS. When paired with the 10-speed automatic, it shifts smoothly around town and provides quick response with sporty driving. The paddle shifters are easy to use and react quickly, making the car feel sharp. Although it does not match the V8 on the highway, this engine still delivers strong real-world performance.
Components from Shelby and Special Editions
Newer models use several parts from Shelby and Mach 1 editions. For example, the Mach 1 uses a Tremec six-speed manual, which many drivers prefer over the regular Mustang manual because it has a better clutch feel. Special edition parts often add track capability and confidence. Drivers have noticed improvement in steering feedback and handling over the years due to updates from these top models.
Things to Consider with the Voodoo Engine
The Voodoo engine from the GT350 had exciting power and a unique sound, but it had known reliability issues. While it was fun to drive and very capable, the concerns about longevity made it less attractive for some buyers. Many are now happy that the newer combinations use proven, more reliable engines and components.
Cabin Look and Comfort
Classic-Inspired Interior Details
The inside of the Mustang draws on past styles. Features like the steering wheel, metal toggle switches, and the engine start button all have a vintage look that stands out. Oil pressure gauges are right in front, adding to the classic feeling.
Modern Digital Displays
A digital gauge cluster gives key driving information. Many drivers appreciate how easy it is to read and how it updates in real time. It offers a good mix of useful data and modern styling.
Center Screen and Button Layout
The center infotainment system is simple to use and set up in a user-friendly way. Owners will find that all major controls are easy to reach. The panel uses physical buttons for climate, volume, and tuning, which is helpful for quick adjustments.

It is possible to transform the driving experience for those willing to invest in these changes. For daily driving, upgrades are not necessary, but enthusiasts have plenty of ways to make the Mustang their own.
Everyday Use Behind the Wheel
Driving the 2021 EcoBoost High Performance Mustang every day is a pleasant experience. The 10-speed automatic transmission works smoothly at low speeds and feels quick when switching to sport mode. Paddle shifters respond right away, making the car feel lively. The EcoBoost engine provides strong acceleration, close to what is found in a GT Mustang for city driving.
Fuel efficiency is a strong point for this car. City: over 20 mpg is common. Highway: around 25-26 mpg is typical. These numbers are better than the GT version, which uses more gas in both city and highway situations.
Here is a simple comparison of gas mileage:
| Model | City (mpg) | Highway (mpg) |
|---|---|---|

The digital gauge cluster and infotainment system are easy to use, though sometimes a little slow. There are physical controls for the radio and air conditioning, which make adjusting settings simple.
One downside is that the inside uses a lot of plastic, which comes from keeping the Mustang affordable. Still, for the price, the sporty feel and tech options are good. Getting the upgraded sound system makes a big difference compared to the basic audio.
While the car is fun, it does not always give the driver the best sense of what is happening at the front and rear. In wet weather, the rear-wheel traction can be tricky. Ford has made improvements for the 2021 model, but some drivers may still notice the lack of feedback compared to competing cars.
For normal driving at legal speeds, the Mustang is comfortable and reliable. The car is also easy on gas and has features that make daily trips enjoyable.
Pricing and Value
Mustang models come at different price points. The EcoBoost version can typically be found for about $38,000 when well equipped. The V8 models cost more, usually in the $45,000–$47,000 range. For the level of performance these cars offer, the pricing is considered reasonable compared to similar vehicles.
Here’s a quick look at average pricing:
| Model | Approximate Price |
|---|---|
| EcoBoost | $38,000 |
| V8 Mustang | $45,000–$47,000 |
The Mustang delivers strong performance even in the four-cylinder version, which is nearly as fast as the more expensive GT in everyday driving. Additionally, the four-cylinder model gets better fuel economy:
- City: Over 20 MPG, sometimes close to 25–26 MPG
- Highway: About 25–26 MPG
This makes it a more budget-friendly option for fuel and regular use than the V8, which averages closer to 16 MPG in the city and about 22–23 MPG on the highway.
Interior materials lean towards the basic side, with noticeable use of plastics. Despite this, the retro design elements and features like the digital gauge cluster and user-friendly infotainment system add value. There are also features such as physical buttons for climate and radio controls, which are practical and easy to use. Getting the upgraded sound system can improve the in-car experience without a big price jump.
