2018 Kia Stinger V6 3.3 T-GDI – Video
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®2 disc brakes are standard on the 3.3-liter twin turbo and feature quad-piston front calipers and dual-piston rear calipers.
