Alongside the 2017 Rogue, the Nissan Sentra is getting a refresh and a new engine when it debuts at the 2016 Miami International Auto Show. The Nissan Sentra SR Turbo will put to use a turbocharged four-cylinder engine and some exterior enhancements, which Nissan claims brings its “fun-to-drive factor to a whole new level."
The 1.6-liter Direct Injection Gasoline (DIG) turbocharged engine will produce 188 horsepower (140 kilowatts) and 177 pound-feet (240 newton-meter) of torque. The new power figures represent a 50 percent increase and 41 percent increase respectively over the standard Sentra SR 1.8-liter. If you’re doing the math, that’s 64 more horsepower (47 kilowatt) and 52 more pound-feet (70 newton-meter) torque. That newfound power is paired to either a CVT or a six-speed manual gearbox.
But the power isn’t alone in the performance upgrades. A revised suspension and steering rack - including stiffer front springs - gives the Sentra SR Turbo a sportier feel. Furthermore, the body has been reinforced, larger front disc brakes have been fitted, and even an Active Understeer Control system helps better deliver power to the front wheels.
On the exterior, the SR Turbo doesn’t get much new in the way of looks compared to the standard SR (not that we’re complaining). The LED low beam projector headlights, lower body side sill extensions, and rear spoiler remain, the only noticeable addition coming in the way of 17-inch aluminum-alloy sport wheels.
Inside is a slightly different story. Standard features include a power sliding glass moonroof, a sport interior trim, premium cloth seats, and a 5.8-inch touchscreen display with Apple CarPlay and Android Auto. Opt for the SR Turbo Premium Package, and that includes leather seats, a Bose audio system, a blind spot monitoring system, and Rear Cross Traffic Alert.
Though Nissan hasn’t given official pricing or a release date just yet, expect to see this Sentra SR Turbo in dealers in the next few months, with a price tag slightly above the $20,410 MSRP found on the non-turbo SR.

The Nissan Sentra, the company's third best-selling vehicle behind the Altima and Rogue, has been a mainstay in the compact sedan segment for 35 years and seven generations. Following a consistent stream of product enhancements year after year – along with steadily increasing sales – Sentra kicks things up a few notches – 64, to be precise, if measured in horsepower – with the addition of the new 2017 Sentra SR Turbo.
Based on the popular Sentra SR grade level, which accounts for more than 15 percent total Sentra sales, the new SR Turbo maintains the SR's unique sporty exterior, interior and wheel treatments. Under the skin, however, things get radically different.
At the heart of the 2017 SR Turbo is its new 1.6-liter Direct Injection Gasoline (DIG™) turbocharged engine rated at 188 horsepower at 5,600 RPM and 177 lb-ft of torque at 1,600 - 5,200 RPM – 64 more horsepower and 52 more lb-ft of torque (41% more) than the non-turbo 2017 Sentra SR grade's 1.8-liter powerplant1.
The new 16-valve DOHC aluminum-alloy inline 4-cylinder engine includes a 10.5:1 compression ratio, Continuously Variable Valve Timing Control System (CVTCS), spray-coated and mirror-finish cylinder bores, a variable pressure oil pump and a low-pressure EGR system, which helps lower exhaust gas temperature and improve knock sensitivity.
The Continuously Variable Valve Timing Control System (CVTCS) includes an intermediate lock function on the intake side, while the use of spray-coated and mirror-finish cylinder bores (versus the iron liners) provides an estimated 12 percent reduction in internal friction, which also improves anti-knock performance and reduces engine weight.
The DIG™ system helps improve combustion, enhancing power, torque, economy and emissions, while the use of the turbocharger and intercooler helps boost power. The variable timing control for both intake and exhaust cycles improves low-end engine response.
As expected of a vehicle with an engine like the 1.6-liter turbo, the Sentra SR Turbo is available with a 6-speed manual transmission, with gear ratios selected to take maximum advantage of the engine's powerband and torque curve.
The SR Turbo is also offered with an advanced Xtronic transmission, a version unique to the SR Turbo to match the new engine's performance. The transmission offers a wide gear ratio range of 7.3:1 through use of a sub-planetary gear and smaller pulleys, resulting in high-speed fuel efficiency and responsive acceleration. The SR Turbo's powerful acceleration feel is enhanced with the Xtronic's D-mode step shift program that simulates shifts, giving a more natural acceleration feeling without holding a high rpm constant, letting rpms build as speed builds.
Of course, the new SR Turbo's performance is not only about the engine. To help handle the increased power and torque, significant changes were made to the suspension, steering and brakes to give the new SR Turbo a great driving feel.
The enhancements to the independent strut front/rear torsion beam suspension are designed to handle the increased power and include a 10 percent increase in front spring stiffness. The SR Turbo-specific front and rear dampers have been optimized for use with the 17-inch wheels and tires – front damping has been increased 23 percent and rear damping by 50 percent.
In addition, the suspension benefits from body enhancements that range from increased front cowl thickness to new steering gear mounting. The Electric Power Steering (EPS) system changes include a larger steering motor and revised electronic mapping to provide a balanced feel between reduced effort at parking and low speed situations and enhanced feedback on highways and winding roads.
Larger front brakes and calipers are utilized in the SR Turbo's 4-wheel disc brake system – 11.7-inch vent front (versus the 11.0-inch front discs of the standard Sentra) and 11.5-inch solid rear discs. In addition, the Active Understeer Control system has been optimized for the SR Turbo.
The result of the new powerplant, unique suspension tuning and other enhancements is an improved acceleration feeling from standing starts and highway passing, along with improved handling response and enhanced ride comfort.
Other enhancements to all 2017 Sentra grades include improved interior quietness due to increased front and rear window glass thickness and nearly double the storage capacity in the front center console.
Like the non-Turbo Sentra SR, the exterior is marked by LED low beam projector headlights with LED accents, lower body side sill extensions, rear spoiler with integrated LED brake light, fog lights, chrome exhaust finisher, heated outside mirrors with LED turn signals, and unique design 17-inch aluminum-alloy wheels with 205/50R17 all-season tires.
The new SR Turbo includes a standard power sliding glass moonroof with tilt feature and SR Turbo badging.
The SR Turbo is offered in seven exterior colors: Red Alert, Brilliant Silver, Gun Metallic, Super Black, Aspen White (premium color) and Deep Blue Pearl.
Inside, the SR Turbo (like the non-turbo SR) includes sport interior trim, premium sport cloth seats, driver's seatback pocket and heated front seats. Like all 2017 Sentra SV, SR and SL trim levels, it also features 5.0-inch Advanced Drive-Assist™ Display (ADAD) located between the tachometer and speedometer.
All Sentra grades offer ample roominess in a compact-size exterior – featuring one of the largest interiors in class, with 111.0 cubic feet of total interior volume. Helping make this possible is the long wheelbase (106.3 inches), which helps provide both ample rear seat legroom of 37.4 inches and large trunk capacity of 15.1 cubic feet. The rear seat is a standard 60/40-split fold-down design, adding versatility to the large trunk space.
The high-quality Sentra SR Turbo interior design features soft-touch instrument panel and door armrests, Nissan Intelligent Key® keyless entry and push button ignition system and RearView Monitor. Other features include tilt and telescopic steering column, power windows with driver's one-touch auto up/down with auto reverse, power door locks with auto-locking feature, remote keyless entry and remote trunk and fuel-filler door releases.
An AM/FM/CD system with 5.0-inch color display, SiriusXM® Satellite Radio (SiriusXM® subscription required, sold separately), Bluetooth® Hands-free Phone System and smartphone integration for iPhone® and Android phones are also standard on the SR Turbo.
The optional SR Turbo Premium Package adds leather-appointed seating, auto-dimming inside mirror with HomeLink® Universal Transceiver, Bose® Premium audio system with eight speakers, Blind Spot Warning (BSW)2 and Rear Cross Traffic Alert (RCTA)2.
The Rear Cross Traffic Alert (RCTA) system utilizes radar to help detect a vehicle approaching from either side of the Sentra when backing out of a parking space. The radar-based Blind Spot Warning (BSW) system provides an audible alert if the driver puts the turn signal on with a detected vehicle in the blind spot area of an adjacent lane, and issues a visual alert if a detected vehicle enters the blind spot area in the adjacent lane.
Also offered with the SR Turbo Premium Package is NissanConnectSM with Navigation and Mobile Apps – with 5.8-inch color touch-screen display, Nissan Voice Recognition for audio and navigation, SiriusXM® Traffic and SiriusXM® Travel Link® (SiriusXM® subscription required, sold separately) and NissanConnect Mobile Apps.
The SR Turbo also includes standard Siri Eyes Free™ Voice Recognition, which makes it easy to make and receive calls, receive and send text messages and emails, select and play music from a compatible device, get notifications, request directions and more via a hands-free voice connection to Siri™ commands.
The Sentra SR Turbo's list of standard safety and security features includes the Nissan Advanced Air Bag System (AABS) with dual-stage supplemental front air bags with seat belt and occupant classification sensors; front seat-mounted side impact supplemental air bags; roof-mounted curtain side impact supplemental air bags with rollover sensor for front and rear-seat outboard occupant head protection; 3-point front and rear seatbelts, front seat belts with pre-tensioners and load limiters and adjustable upper anchors; and LATCH System (Lower Anchors and Tethers for CHildren).
All trim levels of the 2017 Sentra also offer child safety rear door locks; Zone Body construction featuring front and rear crumple zones and occupant zone; Nissan Immobilizer system and anti-theft alarm system; and Tire Pressure Monitoring System (TPMS) with position monitoring and available Easy Fill Tire Alert system.
In addition to the new Sentra SR Turbo, the 2017 Sentra is offered in four other grade levels: Sentra S (6MT and Xtronic), SV (Xtronic), SR (Xtronic) and SL (Xtronic). For full information, please visit NissanNews.com.
