Tech Spec: 2018 Kia Stinger

Kia Motors has followed through on the promise of a production model of the GT Concept. The all-new 2018 Kia Stinger is the culmination of a years-long journey into the sportback segment.

Riding on a chassis comprised of 55-percent advanced high-strength steel, the Stinger provides an ultra-stiff foundation. This rigidity also helps to reduce NVH for a quieter cabin. The MacPherson front setup features large diameter shock absorbers, high-strength wheel bearings and an aluminum strut brace, while the reinforced five-link rear suspension is mounted to a stiffened rear subframe.

The base Stinger rides on a passive suspension tuned to offer a balance of handling and ride comfort, while the GT trim is available with Kia’s first continuously damping electronically controlled suspension, called dynamic stability damping control (DSDC). While aiming to predict the driver’s inputs, depending on road conditions and driving style, DSDC can be tuned to respond with more agility through corners as the system softens the front shocks and firms up the rear. Conversely, improved high-speed stability is achieved when the system stiffens the front shocks and softens the rear. The system is accessed by the driver through five modes: custom, eco, sport, comfort and smart.

If the chassis symbolizes the bones of a gran turismo, then surely the available powertrains represent its heart. Oriented longitudinally and set rearward beneath the long, sculpted hood, a choice of two turbocharged engines is available.

The 2.0-liter twin-scroll turbocharged four-cylinder Theta II engine produces 225 horsepower at 6,200 rpm with 260 pound-feet of maximum torque available from 1,400-4,000 rpm, propelling the Stinger from 0-60 mph in just 5.9 seconds. Performance credentials are further enhanced through the available 3.3-liter twin-turbo V6 Lambda II engine, which produces 365 horsepower at 6,000 rpm and offers 376 pound-feet of torque from 1,350-4,500 rpm. Pushing the twin turbocharged V6 to its full potential will allow the Stinger GT to achieve a governed top speed of 167 mph.

The Stinger is Kia’s first sedan available with rear- or all-wheel drive. Rear-wheel biased for control in the wet or dry, the in-house engineered AWD system6 monitors driver inputs and road conditions and automatically distributes power in real-time based on driving situation. The advanced AWD system is engineered to enhance turn-in and reduce understeer by applying braking force to the inner wheels. The system also freely distributes torque between the front and rear wheels, depending on driving conditions. Should the system detect slip, power is seamlessly directed toward the front or rear wheels, depending on the driving condition. Up to 50 percent of torque can be distributed to the front wheels, and the Stinger’s AWD system is fully integrated with its drive mode settings.

A choice of alloy wheels and tires is also offered. The 2.0-liter turbocharged four-cylinder models ride on 225/45R-18 performance all-season tires while the 3.3-liter V6 is shod with staggered ultra-high performance Michelin Pilot Sport 4 tires that have been specifically engineered and tuned for the Stinger, 225/40R-19 in front and 255/35R-19 at the rear.

The Stinger is equipped with numerous safety features. One, a Kia first, is the driver attention warning system, which is designed to help combat distracted or drowsy driving. The system monitors a number of inputs from the vehicle and the driver and will sound a warning chime and display graphic in the instrument binnacle that it’s time to take a break from driving if it senses the driver’s attention level has been significantly reduced.

Forward collision avoidance with pedestrian detection is designed to monitor vehicles and pedestrians ahead of the vehicle, and if it detects a potential collision with another vehicle or pedestrian, it works to help bring the car to a halt. Smart cruise control with stop and go is designed to maintain a pre-set distance between the Stinger and the vehicle in front and can bring the car to a full stop in traffic. Lane keeping assist is designed to detect and monitor the vehicle’s intended lane, and in certain situations, alert the driver with an audible warning along with providing steering input to help maintain the vehicle’s position. Blind spot collision warning includes rear cross-traffic collision warning, which scans the area behind the vehicle when backing from a parking space and can alert the driver with an audible warning if it detects cross traffic.

The available height-adjustable color head-up display enables the driver to see driving information projected on the windshield glass, including speed, turn-by-turn navigation, audio and cruise control settings and blind spot collision warning information. Bluetooth hands-free operation is standard, while many of the vehicle’s subsystems may be accessed through the steering-wheel-mounted controls.

The base audio system for the 2.0-liter turbo features six speakers and a seven-inch touchscreen with the latest version of UVO, Kia’s telematics system. The standard system found in the 3.3-liter twin turbo ups the speaker count to nine and includes an external amplifier.  The available premium Harman/Kardon audio system pumps out 720 watts through an external amplifier to provide crystal-clear music.

The Stinger comes in five trim levels: entry-level Stinger 2.0L, Premium, GT, GT1 and GT2. The Stinger 2.0L has a starting MSRP of $32,900. A top-of-the-line GT2 — with 3.3-liter V6 twin turbo GDI engine, Kia drive wise system, shift-by-wire, Nappa leather seats, head-up display, AWD, all season tires and remote start — carries a price tag of $53,680.
