Joining the company from BMW in December, 2014, Albert Biermann’s first look at the Stinger signaled to him a car that had to live up to its stunning design from behind the wheel. “I think for the Kia brand, the Stinger is like a special event,” notes Biermann. “Because nobody expects such a car, not just the way it looks but also the way it drives. It's a whole different animal.”
Riding on a chassis comprised of 55 percent advanced high-strength steel, the Stinger provides an ultra-stiff foundation for the ride-and-handling engineers to work with. This rigidity also contributes to reduced NVH and a quiet cabin. The MacPherson front and multi-link rear suspension has been tuned to provide optimal feedback to the driver. A Kia first, ride-damping and vehicle handling traits may be modified by the driver through an electronically adjustable suspension known as Dynamic Stability Damping Control. While always reacting predictably to the driver’s inputs, depending on road conditions and driving style, the Stinger 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 through five drive modes (another Kia first): Personal, Eco, Sport, Comfort and Smart.
Standard variable ratio Rack-mounted Motor Driven Power Steering (R-MDPS) offers razor-sharp feedback through direct mounting of the electric motor on the steering rack, enhancing steering response and reducing unwanted vibration from transmitting through the column. Steering boost is also adjustable through the five selectable drive modes.
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 are available.
While both engines are still under development, the standard 2.0-liter turbocharged four-cylinder Theta II engine produces an estimated 255 horsepower at approximately 6,200 rpm. Max torque of 260 lb.-ft. is available from 1,400 – 4,000 rpm. Performance credentials are further enhanced through the available 3.3-liter twin-turbo V6 Lambda II engine, which is anticipated to produce 365 horsepower at an estimated 6,000 rpm and offer max torque of 376 lb.-ft. from 1,300 – 4,500 rpm. Kia is targeting 5.1 seconds to 62 mph and a top speed of 167 mph with the twin turbocharged V6.
The Stinger features a second-generation eight-speed rear-drive automatic transmission. First offered in the K900 luxury sedan, the gearbox has been designed in-house and rewards drivers with crisp shifts and maximized fuel efficiency. More typically found in aviation- and racing-engine applications, the transmission features Kia’s first use of a Centrifugal Pendulum Absorber (CPA) torque converter to help reduce torsional vibrations through the drivetrain. Drivers can let the gearbox manage shifts on its own or may selectively run through the gears via paddle shifters mounted aft of the steering wheel. As with the suspension and steering, up to five different shift patterns may be selected through the vehicle’s electronic drive-mode system. Throttle mapping is also adjusted accordingly.
Recognizing that passionate drivers may not always reside in optimal climes, the Stinger is Kia’s first sedan available with rear- or all-wheel drive. Rear-wheel biased for optimal control in the wet or dry, the AWD system features a new Dynamic Torque Vectoring Control system which monitors driver inputs and road conditions and automatically applies power and braking force to the appropriate wheels to maintain course in adverse conditions. Rear-drive vehicles get the benefit of a mechanical limited slip differential to help evenly distribute power through the rear wheels.
A choice of alloy wheels and tires are also offered. The 2.0-liter turbocharged 4-cylinder models ride on 225/45R-18 performance tires while the 3.3-liter V6 is shod with staggered ultra-high performance rubber; 225/40R-19 in front and 255/35R-19 at the rear. Vented Brembo® disc brakes are standard on the 3.3-liter twin turbo and feature quad-piston front calipers and dual-piston rear calipers.
Advanced Technology & Convenience
Offering luxurious amenities and unexpected features have become part of Kia’s DNA and the Stinger continues that tradition. Multiple Advanced Driver Assistance Systems (ADAS) seamlessly work together to enhance the driving experience.
In the United States, The National Highway Traffic Safety Administration conservatively estimates that 100,000 police-reported crashes are the direct result of driver fatigue each year. This results in an estimated 1,550 deaths, and 71,000 injuries annually. A Kia first is the new Driver Attention Alert (DAA) system 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 a 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 Assistance (FCA)Ⅳ with integrated Autonomous Emergency Braking (AEB)Ⅳ with pedestrian detection can detect a potential collision with another vehicle or pedestrian and help bring the car to a halt. Advanced Smart Cruise Control (ASCC)Ⅳ maintains a pre-set distance between the Stinger and the vehicle in front and can bring the car to a full stop in congested traffic. Lane Keep Assist (LKA)Ⅳ actively monitors the vehicle’s intended lane and will alert the driver with an audible warning along with providing steering input to help maintain the vehicle’s position. Rear Cross Traffic Alert (RCTA) Ⅳ scans the area behind the vehicle when backing from a parking space and will alert the driver with an audible warning if cross traffic is detected.
Connectivity, entertainment and vehicle information can be as important as a dynamic driving experience and the Stinger comes to market with the latest infotainment systems. The height-adjustable color Head-Up Display (HUD) display enables the driver to see key driving information reflected on the windshield glass, including speed, turn-by-turn navigation, audio and cruise control settings and Blind Spot Detection information. Resting within the center console is a wireless Smartphone charging pad and Bluetooth® hands-free operation is standard while many of the vehicle’s subsystems may be accessed through the steering-wheel-mounted controls.
