Nissan Altima 2024: Fuel Economy and Safety Shield 360 Analysis

When choosing a family sedan, you shouldn’t have to decide between saving money at the pump and keeping your loved ones safe. The 2024 Nissan Altima makes a compelling case that you can have both, offering standout fuel efficiency for a non-hybrid alongside Nissan’s comprehensive Safety Shield 360 suite.

But is it the perfect package? While the standard safety technology is impressive, a recent and crucial safety test revealed a specific weakness for rear-seat passengers. This analysis breaks down the Altima’s true strengths—its remarkably efficient powertrains and extensive driver-assist features—and provides clear insight into its most important safety consideration for 2024 buyers.

Decoding the 2024 Altima’s Fuel Economy

The Altima’s fuel efficiency is one of its biggest selling points, especially since it achieves these numbers without a hybrid system. The key is its pairing of a responsive yet frugal engine with an efficient continuously variable transmission (CVT).

Engine Choices and MPG Breakdown

You have two main engine choices, each with a clear purpose:

• Standard 2.5-Liter Four-Cylinder: This 188-horsepower engine is the efficiency champion. It’s paired with Nissan’s Xtronic CVT and is available with either front-wheel drive (FWD) or intelligent all-wheel drive (AWD).
• Available 2.0-Liter VC-Turbo Four-Cylinder: Exclusive to the SR VC-Turbo trim, this variable-compression turbo engine delivers 248 horsepower for a much more spirited driving experience. It is FWD-only and recommends premium fuel for optimal performance.

The following table details how your choice of drivetrain and trim affects the official EPA estimates.

Trim & Drivetrain	EPA City MPG	EPA Highway MPG	Estimated Driving Range*
Altima S, SV (FWD)	27	39	Up to 518 miles
Altima SR, SL (FWD)	27	37	~490 miles
Altima SV, SR, SL (AWD)	26	36	~480 miles
Altima SR VC-Turbo (FWD)	25	34	~470 miles

*Estimated range calculated from EPA MPG and a 16-gallon fuel tank. Actual range will vary.

Real-World Tips to Maximize Your MPG

The EPA numbers show potential, but your driving habits make the final difference. Here are expert-recommended tips to get the most out of every gallon:

• Maintain Tire Pressure: Check monthly and keep tires inflated to the recommended PSI (typically 32-36 psi). Underinflated tires create drag and lower efficiency.
• Reduce Weight and Drag: Remove unnecessary items from your trunk and cabin. Avoid using roof racks when not needed.
• Drive Smoothly: Avoid rapid acceleration and hard braking. Use cruise control on the highway to maintain a steady speed.
• Limit Idling: Turn off the engine if you’re stopped for more than a minute.
• Follow Maintenance Schedule: Regular oil changes and engine air filter replacements are crucial for peak engine efficiency.

Safety Shield 360: Standard Protection, with a Critical Context

Every 2024 Altima comes standard with Nissan’s Safety Shield 360, a suite of six advanced driver-assist systems (ADAS). This is a significant value, as many competitors charge extra for these features.

What’s Included in Safety Shield 360?

• Automatic Emergency Braking with Pedestrian Detection: Can help detect vehicles or pedestrians and apply the brakes if a potential collision is sensed.
• Blind Spot Warning: Alerts you if a vehicle is detected in your blind spot.
• Rear Cross Traffic Alert: Warns of approaching traffic when reversing out of a parking space.
• Lane Departure Warning: Alerts you if you begin to drift out of your lane without a turn signal.
High Beam Assist: Automatically switches between high and low beams based on surrounding traffic. Rear Automatic Braking: Applies the brakes to avoid collisions with objects detected behind the vehicle while in reverse.

Crash Test Report Card

Here is a summary of the 2024 Altima’s key IIHS safety ratings:

Test Category	Rating	Notes
Driver-Side Small Overlap Front	Good	Top score for this severe test.
Passenger-Side Small Overlap Front	Good	Top score for this severe test.
Updated Moderate Overlap Front	Marginal	Downgraded due to Poor rear passenger restraint performance.
Standard Front Crash Prevention (Vehicle-to-Vehicle)	Poor	System did not meet IIHS’s updated, more stringent 2024 criteria.
Headlights	Acceptable	Varies by trim; some trims offer Good-rated lights.

Making the Decision: Is the 2024 Altima Right for You?

Choosing a car is about prioritizing what matters most. Here’s how the Altima stacks up for different buyer priorities.

Choose the Altima if… Your top priorities are excellent fuel economy for long commutes, a comfortable and spacious cabin, and you value having a strong suite of standard driver-assist technology. It is a rational, cost-effective choice for a daily driver.

Consider other options if… Maximum safety for all seating positions is your non-negotiable top priority. The IIHS moderate overlap test result is a significant factor to weigh, especially if you frequently transport adult rear-seat passengers. Also, if you desire an engaging driving experience, reviewers note rivals like the Honda Accord are more fun to drive.

Your Top Altima Fuel Economy & Safety Questions

1. What is the single biggest factor that hurts the Altima’s fuel economy? Choosing all-wheel drive (AWD) has a small, predictable impact, reducing highway MPG by 1-3 MPG depending on the trim. The more significant drop comes from choosing the powerful VC-Turbo engine, which trades some efficiency for performance.

2. How serious is the “Marginal” IIHS crash test rating? It is a serious consideration that distinguishes the Altima from models with top ratings in the same test. The issue specifically involves the safety of rear-seat adult passengers in a frontal crash. Front-seat protection remains highly rated. This information is crucial for making an informed choice.

3. Does the VC-Turbo engine require premium fuel? For optimal performance (the full 248 horsepower), Nissan recommends using premium unleaded fuel. It will run on regular, but you may experience reduced power and efficiency.

4. What is “submarining” in a crash? Submarining occurs when a passenger’s body slides forward under the lap belt during a frontal collision. Instead of restraining the strong pelvic bones, the belt can ride up onto the softer abdomen, increasing the risk of serious internal injuries.

5. How does the Altima’s MPG compare to hybrid sedans? The Altima’s top 39 MPG highway is impressive for a non-hybrid but is generally lower than the combined MPG of modern hybrid rivals like the Toyota Camry Hybrid (44-46 MPG combined). The Altima’s advantage is a lower initial purchase price compared to most hybrids.

6. Is ProPILOT Assist worth it? Available on higher trims, ProPILOT Assist is a hands-on driver-assist system that combines intelligent cruise control with lane-centering. It can significantly reduce driver fatigue on long highway trips and is a worthwhile upgrade for frequent commuters or road-trippers.

The 2024 Nissan Altima presents a compelling case as a smart, efficient, and well-equipped family sedan. Its standout fuel economy and standard Safety Shield 360 tech package offer tremendous everyday value. However, the recent IIHS crash test results introduce an important and complex safety consideration that prioritizes front-seat over rear-seat protection.

Your final decision should weigh the car’s excellent efficiency and features against this specific safety profile. For drivers primarily concerned with front-seat safety and low running costs, the Altima remains a strong contender. For families who prioritize maximum safety for all passengers, this new data is essential to review before making a choice.
