When it comes to vehicle safety, braking performance is paramount. It's not just about how quickly a car can accelerate; it's equally, if not more, important to know how effectively it can bring itself to a halt. Subaru, a brand renowned for its All-Wheel Drive systems and robust engineering, has consistently focused on delivering a comprehensive safety package in its vehicles. The Subaru Impreza Sport Premium, a popular choice for those seeking a blend of practicality, all-weather capability, and engaging driving dynamics, is no exception. This article delves into the braking performance of the Impreza Sport Premium, exploring its effectiveness and how it compares to key competitors in its class.

Understanding Braking Metrics
Before we examine the Impreza Sport Premium's specific figures, it's crucial to understand what constitutes good braking performance. The most common metric used is the stopping distance from a specific speed, usually 60 or 70 miles per hour (mph). A shorter stopping distance indicates a more efficient and responsive braking system. Factors influencing this include the brake pad material, disc size and type, tyre grip, the vehicle's weight, and the effectiveness of the anti-lock braking system (ABS).
The Subaru Impreza Sport Premium, when tested, demonstrated some truly remarkable braking capabilities. Rolling on its standard 205/50-17 all-season tyres, the Impreza managed to stop from 70 mph in an impressive 164 feet. This figure is not just good; it's deceptively so, meaning it might perform even better under optimal conditions or with different tyre choices. What makes this particularly noteworthy is the context provided by comparative tests. In one instance, the Impreza Sport Premium stopped a staggering 20 feet shorter than a 2012 Honda Civic EX sedan and 19 feet shorter than a 2012 Mazda 3 i Touring that were also tested. This significant difference highlights the advanced engineering and tuning Subaru has applied to the Impreza's braking system.
Why Such Strong Performance?
Several elements likely contribute to the Impreza Sport Premium's superior braking. Firstly, Subaru vehicles often feature a well-balanced chassis and a well-calibrated braking system that works in harmony with their Symmetrical All-Wheel Drive. While AWD is primarily associated with traction during acceleration, it can also play a role in stability during braking, helping to keep the vehicle planted. The specific brake components, such as the brake calipers, rotors, and brake fluid, are chosen and engineered for optimal performance. Furthermore, the all-season tyres, while designed for versatility, in this specific test, provided ample grip to achieve these short stopping distances.
To truly appreciate the Impreza Sport Premium's braking prowess, a direct comparison is invaluable. Let's look at the figures mentioned:
| Vehicle Model | Stopping Distance from 70 mph | Notes |
|---|---|---|
| Subaru Impreza Sport Premium | 164 feet | Standard 205/50-17 all-season tyres |
| 2012 Honda Civic EX sedan | 184 feet | Competitor tested under similar conditions |
| 2012 Mazda 3 i Touring | 183 feet | Competitor tested under similar conditions |
As the table clearly illustrates, the Impreza Sport Premium significantly outperforms its rivals in this critical safety aspect. These aren't minor margins; these are substantial differences that could be crucial in an emergency situation. For a driver, an extra 19-20 feet of stopping distance can be the difference between a minor incident and a serious collision.

Factors Influencing Real-World Braking
While test figures provide an excellent benchmark, it's important to acknowledge that real-world braking performance can vary. Several factors can influence how effectively a car stops: * Tyre Condition and Type: While the Impreza performed well on its stock all-season tyres, switching to performance-oriented summer tyres could yield even shorter stopping distances, albeit at the expense of all-weather capability. Conversely, worn tyres or tyres with less tread depth will naturally increase stopping distances. * Brake Condition: Regular maintenance is key. Worn brake pads, glazed rotors, or contaminated brake fluid can all degrade braking performance. Ensuring your brakes are in good condition is vital. * Road Surface and Conditions: Braking distances will be longer on wet, icy, or gravel surfaces compared to dry asphalt. The test figures are typically achieved under ideal dry conditions. * Driver Input: How a driver applies the brakes can also make a difference. Modern ABS systems are designed to provide optimal braking pressure, but smooth, firm application is generally recommended. * Vehicle Load: A heavier vehicle will generally require a longer distance to stop.
The Importance of a Responsive Braking System
A responsive braking system is not just about stopping distances; it's also about the feel and confidence it inspires in the driver. The Impreza Sport Premium's braking system is designed to provide consistent pedal feel and effective deceleration, allowing drivers to feel more in control, especially in challenging driving conditions. This confidence is amplified by Subaru's commitment to safety, which includes a suite of advanced driver-assistance systems that often work in conjunction with the braking system.
FAQs about Subaru Impreza Braking
Q1: Does the Subaru Impreza have good brakes?A1: Yes, the Subaru Impreza Sport Premium has demonstrated exceptionally good braking performance in tests, stopping significantly shorter distances than some of its key competitors.
