When buying your first car, understanding power and torque is key to picking the right vehicle. Here's a quick breakdown:
Power (kilowatts, kW): Determines how fast a car can go - important for highway driving and maintaining speed.
Torque (pound-feet, lb-ft): Affects acceleration and towing - key for city driving, climbing hills, and hauling loads.
For city driving, aim for 110-150 kW
For highway cruising, look for 150-185 kW
For towing or hauling, go for 185+ kW
Balance matters: More power means higher speeds, while torque ensures quick acceleration and towing ability. Choose based on your driving habits and needs, then test drive to feel the difference.
Engine power, measured in kilowatts (kW), reflects how much work an engine can perform. More kw generally means higher top speeds. For most everyday drivers, a moderate kw level is enough to ensure an efficient and responsive driving experience during daily commutes.
Torque refers to the twisting force generated by the engine, measured in Newton-meters (Nm), the standard unit used in Australia. This force impacts how quickly a vehicle can accelerate from a standstill and how well it handles tasks like towing or hauling. Trucks and heavy-duty vehicles are designed with higher torque for demanding tasks, while everyday cars balance torque for smooth and responsive driving.
Power and torque work together to shape a car's performance. Here's how they play different roles in various driving scenarios:
|
Performance Aspect |
Power's Role |
Torque's Role |
|---|---|---|
|
City Driving |
Rarely needed – full power isn't often used |
Key for quick acceleration from stops |
|
Highway Driving |
Essential for maintaining high speeds |
Less important at steady speeds |
|
Hill Climbing |
Helps maintain speed uphill |
Critical for starting climbs and low-speed ascents |
|
Towing |
Keeps speed steady under load |
Vital for moving loads and climbing hills |
In everyday driving, torque often feels more impactful than power, especially in stop-and-go traffic or when merging onto highways. A car with balanced torque provides a responsive and capable driving experience, even if its power figures aren't particularly high.
Let’s take a closer look at how power and torque influence your driving experience.
Kilowatts (kW) determine a car’s top speed, while torque (Nm) is what gets you moving quickly. For instance, a sedan with 149 kW and 251 Nm of torque can go from 0 to 100 km/h in 7.5 seconds. On the other hand, the 2024 Toyota GR Supra, boasting 285 kW and 499 Nm of torque, achieves the same in just 3.8 seconds.
Here’s how power and torque come into play in different driving scenarios:
|
Driving Situation |
Role of Power |
Role of Torque |
|---|---|---|
|
Highway Merging |
Helps with 64-113 km/h acceleration |
Provides the initial thrust |
|
Mountain Driving |
Keeps speed steady on long climbs |
Essential for handling steep inclines |
Torque is the real hero when it comes to towing. While speed and acceleration are important for everyday driving, torque enables vehicles to tow heavy loads effectively. Take the 2025 Ford F-150 with its 3.5L EcoBoost V6 engine. It generates 540 Nm of torque, allowing it to tow up to 6,350 kg. This capability ensures it can pull from a standstill, climb hills, and handle varying road conditions with ease.
Power and torque also play a role in fuel efficiency. Turbocharged engines, for example, strike a balance between performance and fuel economy. The 2025 Honda Accord’s 1.5L engine delivers 143 kW and 260 Nm of torque while achieving an impressive 7.4 L/100 km in the city and 5.7 L/100 km on the highway. This combination offers:
Choosing the right power and torque for your vehicle is all about aligning features with your driving habits and needs.
Start by thinking about where and how you drive. For city driving, moderate power is usually enough to keep things efficient. If you’re on the highway often, you’ll want more power to handle smooth acceleration. Tackling hilly terrain or hauling heavy loads? That’s when higher torque becomes essential. Don’t forget to factor in how many passengers or how much cargo you typically carry - these affect performance requirements too.
The type of vehicle you choose also plays a big role in determining the right power and torque levels.
Different types of vehicles are built to meet specific driving needs:
Compact Cars: Designed for efficiency, these are great for daily commutes and urban driving, offering just enough power to get the job done.
Midsize Sedans: Striking a balance between performance and fuel economy, these vehicles deliver a smooth and responsive drive without guzzling gas.
SUVs and Crossovers: Built for versatility, they pack enough power for quick acceleration and can handle occasional towing when needed.
When you’re test driving a car, focus on how it handles in real-world conditions:
Test how quickly and smoothly it accelerates from a stop.
Drive up an incline to see how well the engine manages the climb.
Merge onto a highway to check if the transition into traffic feels seamless.
Also, pay close attention to how responsive the engine feels at different speeds. Many modern cars now come with adjustable driving modes - these let you switch between settings focused on fuel efficiency or performance, depending on your style of driving.
Once you've determined your performance needs, it's time to find financing that fits your budget.
Upgrading performance features can increase both the initial purchase price and ongoing expenses like fuel, insurance, and maintenance. If you're a first-time buyer, it's crucial to weigh these costs against the benefits. Ensuring these upgrades align with your financial situation can help you make a practical and sustainable choice for your driving needs.

Understanding power and torque is crucial when choosing a car, as they impact both driving performance and costs. Your ideal power and torque depend on how you plan to use the vehicle.
For city driving, a power range of 110-150 kW and torque of 200-300 Nm is usually enough. This setup offers good fuel efficiency and makes parking easier. If you frequently drive on highways, look for vehicles with 150-190 kW of power and 300-350 Nm of torque for smoother cruising and confident overtaking. For towing or hauling, you'll need over 190 kW of power and 350 Nm of torque to handle heavy loads effectively.
Here’s a quick guide to match performance with your driving needs:
|
