2017-2019 Nissan Sentra VII (B17 facelift ) NISMO 1.6 (188 Hp) Xtronic CVT

The Nissan Sentra VII (B17), specifically the NISMO 1.6 variant equipped with the Xtronic CVT, represents a performance-oriented iteration of the seventh-generation Sentra, produced from 2017 to 2019. This model aimed to inject a degree of sportiness into the traditionally economy-focused compact sedan. Positioned as the top-tier trim level during its production run, the NISMO 1.6 offered a more powerful engine and unique styling cues compared to the base and mid-range Sentra models. It was designed to appeal to buyers seeking a blend of practicality, fuel efficiency, and a more engaging driving experience within the compact car segment.

Nissan Sentra B17 NISMO 1.6: An Overview

The B17 Sentra underwent a facelift in 2016, introducing revised front and rear styling, along with interior enhancements. The NISMO 1.6, introduced shortly after, capitalized on these updates with further aesthetic and mechanical upgrades. It was built on the Nissan Sylphy platform (B17), shared with other global Nissan models. The introduction of the NISMO trim signaled Nissan’s intent to broaden the Sentra’s appeal beyond its core customer base, attracting a younger and more performance-conscious demographic.

Powertrain & Engine Architecture

The heart of the NISMO 1.6 is the MR16DDT 1.6-liter inline-four cylinder engine. This engine is a turbocharged gasoline direct injection (GDI) powerplant, producing 188 horsepower at 5600 rpm and 240 Nm (177.01 lb-ft) of torque at 5200 rpm. The direct injection system optimizes fuel delivery for improved efficiency and power output. The engine utilizes a DOHC (Double Overhead Camshaft) valvetrain with Continuously Variable Valve Timing Control System (CVTCS) to enhance responsiveness and broaden the torque curve. The turbocharger, coupled with an intercooler, significantly boosts power output compared to the naturally aspirated engines offered in other Sentra trims.

The engine is transversely mounted at the front of the vehicle. Power is transmitted to the front wheels via Nissan’s Xtronic CVT (Continuously Variable Transmission). This CVT is designed to provide smooth, seamless acceleration and contribute to improved fuel economy. While CVTs are known for their efficiency, Nissan tuned the Xtronic CVT in the NISMO 1.6 to simulate stepped gear changes, offering a more conventional driving feel. The engine requires 4.4 liters (4.65 US quarts / 3.87 UK quarts) of engine oil, specified to Nissan’s standards, and the cooling system holds 8.7 liters (9.19 US quarts / 7.65 UK quarts) of coolant.

Transmission Details: Xtronic CVT

The Xtronic CVT used in the NISMO 1.6 is a belt-driven system, offering an infinite number of gear ratios within its operating range. This allows the engine to operate at its most efficient point for any given driving condition. While some drivers prefer the direct feel of a traditional automatic transmission, the Xtronic CVT in the NISMO 1.6 was programmed to mimic traditional gear shifts, providing a more engaging experience. The CVT’s programming prioritizes responsiveness and acceleration, aligning with the NISMO trim’s performance focus.

Driving Characteristics

The NISMO 1.6 offers a noticeable performance upgrade over the standard Sentra models. The turbocharged engine delivers strong acceleration, particularly in the mid-range, making overtaking and merging onto highways easier. The CVT, while not offering the immediate response of a dual-clutch transmission, provides smooth and efficient power delivery. The weight-to-power ratio of 7.5 kg/Hp and a weight-to-torque ratio of 5.9 kg/Nm contribute to a reasonably spirited driving experience. Compared to the base 1.8L Sentra, the NISMO 1.6 feels significantly more powerful and responsive. However, it doesn’t match the outright performance of sport-compact cars like the Honda Civic Si or Volkswagen GTI.

The steering is light and precise, providing adequate feedback for everyday driving. The suspension is tuned for a balance between comfort and handling, offering a slightly firmer ride than the standard Sentra but remaining compliant enough for daily commutes. The NISMO trim benefits from subtle suspension tweaks that reduce body roll and improve cornering stability.

Equipment & Trim Levels

The NISMO 1.6 came standard with a comprehensive list of features, including NissanConnect with Mobile Apps, a 5.8-inch touchscreen display, Bluetooth connectivity, and a rearview camera. Standard interior features included sport seats with unique NISMO upholstery, a leather-wrapped steering wheel, and aluminum pedal covers. Exterior features included a unique NISMO front fascia, side skirts, rear spoiler, and dark-finished alloy wheels. Optional extras included a premium audio system, navigation, and advanced safety features like blind-spot monitoring and rear cross-traffic alert.

Chassis & Braking

The Sentra NISMO 1.6 utilizes an independent coil spring suspension in the front and a torsion beam suspension in the rear. The front suspension geometry is optimized for handling, while the rear torsion beam provides a balance between ride comfort and stability. The braking system consists of ventilated discs in the front (297 mm) and solid discs in the rear (292 mm). The vehicle is equipped with ABS (Anti-lock Braking System) as standard. The tires are size 215/45 R18, mounted on 18-inch alloy wheels.

Market Reception & Comparison

The NISMO 1.6 was generally well-received by automotive critics, who praised its improved performance and sporty styling. However, some reviewers noted that the CVT, while improved, still lacked the engagement of a traditional automatic or manual transmission. Fuel economy was rated at 8.7 l/100 km (27 US mpg / 32.5 UK mpg combined), which is competitive for its class. Compared to other Sentra trims, the NISMO 1.6 offered a more engaging driving experience but came at a higher price point. Reliability was generally good, consistent with Nissan’s reputation for building durable vehicles.

Technical Specifications

Legacy

The Nissan Sentra B17 NISMO 1.6 represents a relatively rare and sought-after variant within the seventh-generation Sentra lineup. While not a high-volume seller, it offered a compelling combination of performance, fuel efficiency, and features. On the used car market, the NISMO 1.6 commands a premium over the standard Sentra models. The MR16DDT engine, when properly maintained, is known for its reliability. Common maintenance items include regular oil changes, timing chain inspection, and turbocharger health checks. The Xtronic CVT, while generally durable, requires periodic fluid changes to ensure optimal performance and longevity. The B17 NISMO 1.6 remains a viable option for buyers seeking an affordable and sporty compact sedan.
