2020 Nissan Sentra Vs 2020 Nissan Altima

The 2020 Nissan Sentra and Altima represent two distinct classes within the Nissan sedan lineup: the compact and the mid-size, respectively. While both share a similar design language, they cater to different needs and preferences. This article provides an in-depth, technical comparison of the two vehicles, delving into their mechanical differences, performance characteristics, interior appointments, and technological features. We aim to equip you with the knowledge necessary to understand the nuances that separate these two popular Nissan models.

Powertrain and Performance

Perhaps the most significant difference lies beneath the hood. The 2020 Nissan Sentra typically offers a smaller, more fuel-efficient engine, while the Altima boasts a larger, more powerful option. Let's break down the specifics:

2020 Nissan Sentra

The Sentra typically features a 2.0-liter naturally aspirated four-cylinder engine. This engine is designed for fuel economy and everyday usability rather than outright performance. Expect horsepower figures in the range of 149 hp and torque around 146 lb-ft.

Key technical aspects of the Sentra's engine include:

• Engine Code: MR20DD (typically)
• Valve Train: DOHC (Double Overhead Camshaft) with four valves per cylinder. This allows for precise control over intake and exhaust timing.
• Fuel Delivery: Direct Injection (DI). DI injects fuel directly into the combustion chamber, resulting in more efficient combustion and improved power output compared to port injection.
• Transmission: Continuously Variable Transmission (CVT) is the standard offering. The CVT provides seamless gear changes, optimizing fuel economy by keeping the engine in its most efficient operating range.

The Sentra’s CVT, while smooth, can sometimes feel less engaging than a traditional automatic transmission, especially during spirited driving. However, Nissan has made strides in improving the responsiveness and feel of their CVTs over the years.

2020 Nissan Altima

The Altima offers two engine options. The base engine is a 2.5-liter naturally aspirated four-cylinder, producing approximately 188 hp and 180 lb-ft of torque. An optional turbocharged 2.0-liter VC-Turbo (Variable Compression Turbo) engine is also available, offering significantly more power, around 248 hp and 273 lb-ft of torque. This innovative engine dynamically adjusts its compression ratio to optimize for either power or efficiency.

Here’s a closer look at the Altima’s engine options:

• 2.5L Engine Code: QR25DE
• 2.0L VC-Turbo Engine Code: KR20DDET
• Valve Train (Both): DOHC with four valves per cylinder
• Fuel Delivery (Both): Direct Injection
• VC-Turbo Technology: The VC-Turbo engine utilizes a multi-link system that varies the piston stroke, effectively altering the compression ratio. This allows the engine to operate at a high compression ratio for fuel efficiency during cruising and a lower compression ratio for increased power under acceleration.

  This technology is a major advancement in internal combustion engine design.

• Transmission (Both): CVT. Similar to the Sentra, the Altima utilizes a CVT for both engine options. However, the CVT in the Altima is generally engineered to handle the higher torque output of the larger engines.

The Altima’s VC-Turbo engine stands out for its innovative approach to maximizing both performance and fuel efficiency. This engine represents a significant technological leap compared to the Sentra’s powerplant.

Chassis and Suspension

The chassis and suspension systems also differ significantly between the Sentra and Altima, reflecting their intended purposes and target markets.

2020 Nissan Sentra

The Sentra employs a front-wheel-drive configuration with a MacPherson strut front suspension and a multi-link rear suspension. This setup provides a good balance of ride comfort and handling. The suspension is tuned to prioritize a smooth and comfortable ride for everyday driving.

Key suspension components include:

• Front Suspension: MacPherson struts with coil springs and stabilizer bar.
• Rear Suspension: Multi-link independent suspension with coil springs and stabilizer bar.
• Steering: Electric Power Steering (EPS). EPS provides variable steering assistance, making it easier to maneuver at low speeds while providing a more stable feel at higher speeds.

2020 Nissan Altima

The Altima also utilizes a front-wheel-drive configuration, but with a slightly more sophisticated suspension setup, particularly in higher trim levels. The front suspension is also MacPherson strut, but the rear suspension is a multi-link design optimized for improved handling and stability. All-wheel drive (AWD) is also available on certain Altima trims, further enhancing traction and handling in adverse weather conditions.

Key features of the Altima's chassis and suspension:

• Front Suspension: MacPherson struts with coil springs and stabilizer bar.
• Rear Suspension: Multi-link independent suspension with coil springs and stabilizer bar, often tuned for a slightly firmer ride than the Sentra.
• Steering: Electric Power Steering (EPS). The EPS system in the Altima may be calibrated differently to provide a heavier and more responsive feel compared to the Sentra.
• Available AWD: The Intelligent AWD system available on the Altima can automatically distribute torque between the front and rear wheels to optimize traction based on driving conditions. This system uses sensors to monitor wheel slip, throttle input, and steering angle to proactively engage AWD.

The Altima’s available AWD system is a significant differentiator, providing enhanced stability and control in slippery conditions, a feature not offered on the Sentra.

Interior Space and Features

The Altima, as a mid-size sedan, offers significantly more interior space than the compact Sentra. This translates to more legroom, headroom, and shoulder room for both front and rear passengers. The trunk capacity is also larger in the Altima.

The interiors of both vehicles generally follow a similar design aesthetic, but the Altima often features higher-quality materials and more advanced technology, particularly in higher trim levels. For example, leather upholstery, larger infotainment screens, and advanced driver-assistance systems are more commonly found in the Altima.

The key difference is the *experience*. The Sentra offers a great value, while Altima gives a taste of luxury.

Technology and Safety

Both the Sentra and Altima come equipped with a range of standard and available technology and safety features. However, the Altima typically offers a more comprehensive suite of advanced driver-assistance systems (ADAS).

Common Features (Both):

• Automatic Emergency Braking (AEB)
• Lane Departure Warning (LDW)
• Blind Spot Warning (BSW)
• Rear Cross Traffic Alert (RCTA)

Features More Common on Altima:

• Adaptive Cruise Control (ACC) – Maintains a set distance from the vehicle ahead.
• ProPILOT Assist – Combines ACC and Lane Keep Assist for semi-autonomous driving in certain conditions.
• 360-Degree Around View Monitor – Provides a bird's-eye view of the vehicle for easier parking and maneuvering.
• Larger Touchscreen Infotainment Systems – Often with more advanced features and smartphone integration.

The Altima's ProPILOT Assist is a noteworthy feature that enhances driving convenience and safety by providing semi-autonomous driving capabilities. While the Sentra may offer some similar features, they are typically less advanced or comprehensive.

Conclusion

The 2020 Nissan Sentra and Altima cater to different needs and priorities. The Sentra is an excellent choice for buyers seeking a fuel-efficient and affordable compact sedan. Its smaller size makes it easier to maneuver in urban environments, and its lower price point makes it an attractive option for budget-conscious consumers.

The Altima, on the other hand, offers more space, power, and advanced features. Its larger size makes it more comfortable for families and those who frequently transport passengers or cargo. The available VC-Turbo engine and AWD system provide enhanced performance and capability, while the more extensive suite of ADAS features contributes to a safer and more convenient driving experience. The availability of AWD in certain Altima trim levels adds to its versatility.

Ultimately, the best choice depends on your individual needs and preferences. Consider your budget, driving habits, and passenger/cargo requirements when making your decision. By understanding the technical differences between these two vehicles, you can make a more informed choice and select the Nissan sedan that best suits your lifestyle.
