Car technology has evolved rapidly in recent years, offering features that make driving safer, more convenient, and more enjoyable. Whether you’re shopping for a new vehicle or just trying to understand what’s available, it’s important to know how these features work, and which ones might best fit your needs. For a deeper dive into affordability, read our cost comparison of combustion, PHEV, and EV vehicles.

This guide breaks down the most common car technologies available today, providing easy-to-understand explanations so you can make informed decisions when buying your next car.

Safety Features: Protecting You on the Road

Modern cars come equipped with a variety of advanced safety features designed to prevent accidents and protect passengers. Here are some of the most popular ones you’ll encounter:

Blind Spot Monitoring (BSM): Blind spot monitoring uses sensors to detect vehicles in your blind spots—those areas just outside your rearview mirrors where another car can “hide.” If a car is detected, the system alerts you with a visual or audible warning to avoid potential collisions.

Lane Departure Warning (LDW) & Lane Keeping Assist (LKA): LDW alerts you when your vehicle drifts out of its lane without signaling, helping prevent unintended lane changes. LKA takes it a step further by gently steering your vehicle back into the lane if you don’t correct your position in time.

Adaptive Cruise Control (ACC): This smart version of traditional cruise control adjusts your car’s speed to maintain a safe following distance from the vehicle ahead. It can slow down or speed up automatically, making highway driving more relaxing and efficient.

Automatic Emergency Braking (AEB): AEB systems detect potential collisions and automatically apply the brakes if you don’t react in time. This can help prevent accidents or reduce their severity.

Cross-Traffic Alert: When backing out of a parking space, cross-traffic alert warns you if a vehicle is approaching from the side. This is especially useful in crowded parking lots with limited visibility.

360-Degree Camera Systems: By using multiple cameras positioned around the car, this system provides a “bird’s-eye” view of your surroundings, making parking and maneuvering in tight spaces easier and safer.

Parking Assist: Some cars can now park themselves! With parking assist, sensors guide the car into a parking space with minimal input from the driver, making parallel and perpendicular parking a breeze.

Convenience Features: Making Driving Easier

Many modern features are designed to enhance your driving comfort and convenience, turning your vehicle into a mobile command center.

Keyless Entry & Push-Button Start: No more fumbling for your keys—keyless entry allows you to unlock and start your car without taking the key fob out of your pocket or purse.

Digital Keys: Some manufacturers now offer digital key technology, allowing drivers to use their smartphones to lock, unlock, and start their vehicles, adding a layer of convenience and security.

Apple CarPlay & Android Auto: These systems connect your smartphone to the car’s infotainment system, allowing you to use apps like navigation, music streaming, and voice commands safely while driving.

Head-Up Display (HUD): HUD projects important information, like your speed and navigation directions, onto the windshield so you can stay focused on the road.

Voice Control: Modern cars allow you to control many functions—such as adjusting climate settings, making phone calls, and setting navigation—using simple voice commands.

Over-the-Air (OTA) Updates; Some vehicles now receive software updates remotely, adding new features or improving performance without requiring a trip to the dealership.

Wireless Charging: Forget tangled cords—wireless charging pads built into the vehicle allow you to charge your compatible smartphone without plugging it in.

Driver Assistance Features: The Future of Driving

Many newer cars come with driver assistance systems that can help you drive more confidently and safely.

Adaptive Headlights: These headlights automatically adjust their angle and brightness based on your speed and road conditions, improving visibility at night.

Traffic Sign Recognition: Traffic Sign Recognition (TSR) uses cameras to detect road signs, such as speed limits, stop signs, and no-entry signs, and displays them on your dashboard or HUD. Some systems also cross-reference GPS and mapping data to verify speed limits and provide information when road signs are missing or obstructed.

Driver Attention Monitoring: This system can detect signs of drowsiness or distraction, such as erratic steering or long periods without steering input and provide alerts to encourage you to take a break.

Semi-Autonomous Driving (Hands-Free Driving): While not fully self-driving, semi-autonomous systems can control steering, acceleration, and braking on highways. However, they still require the driver to stay attentive and ready to take over when needed. While semi-autonomous driving systems like Tesla Autopilot, GM Super Cruise, and Ford BlueCruise can assist on highways, they still require driver attention. No consumer car today offers fully self-driving capabilities.

Additional Consideration

Subscription-Based Features: As noted, certain features like heated seats or advanced driver assistance systems may require ongoing subscriptions. It’s advisable to clarify which features are included and which require additional payments when considering a vehicle purchase.

Electric and Hybrid Cars: What You Need to Know

With the rise of electric vehicles (EVs) and hybrids, it’s important to understand their key features and benefits to determine if they’re right for you.

Electric Vehicles (EVs): EVs run solely on electricity, using large batteries instead of gasoline engines. They offer zero emissions, lower operating costs, and quiet operation. However, range and charging availability should be considered before purchasing.

When buying an EV, consider charging infrastructure in your area. Home charging is ideal, but for road trips, fast-charging networks like Tesla Superchargers, Electrify America, and EVgo vary in availability and speed.

Key features to look for in an EV:

• Battery Range: The distance an EV can travel on a single charge. Typical ranges vary from 150 to over 400 miles, depending on the model.
• Charging Time: Some EVs offer fast-charging capabilities, which can add significant range in under 30 minutes.
• Regenerative Braking: This feature captures energy when slowing down, sending it back to the battery to improve efficiency.
• Connectivity: Many EVs offer apps that allow you to monitor charging, schedule departures, and pre-condition the cabin remotely.

Hybrid Vehicles: Hybrids use both a gasoline engine and an electric motor, offering improved fuel efficiency and lower emissions compared to traditional gas-powered cars. They don’t require charging, as they generate electricity through braking and the gas engine.

Key features to look for in a hybrid:

• Fuel Economy: Hybrids offer excellent gas mileage, especially in stop-and-go traffic.
• Hybrid Modes: Many hybrids have selectable driving modes that let you prioritize fuel efficiency or performance.
• Battery Longevity: While modern hybrid batteries are built to be durable, their longevity can vary. Understanding the manufacturer’s warranty and being aware of factors that affect battery life are essential steps in making an informed decision

Plug-In Hybrid Vehicles (PHEVs): PHEVs combine the best of both worlds—allowing you to drive short distances solely on electric power alone and switching to gas for longer trips. They require charging but offer flexibility for various driving needs.

Choosing the Right Tech for Your Needs

With so much technology available, it’s important to focus on the features that best suit your lifestyle and driving habits.

If you prioritize safety, features like adaptive cruise control, automatic emergency braking, and blind-spot monitoring should be at the top of your list.

For drivers who enjoy connectivity, Apple CarPlay, wireless charging, and voice controls can make every trip more enjoyable and seamless.

If you’re looking for fuel efficiency, hybrids and EVs offer excellent options with long-term savings on fuel and maintenance.

Be aware that some manufacturers now offer certain features, like heated seats and advanced driver assistance, as subscription-based upgrades. Be sure to check if key features require additional payments over time.
