Kia today unveiled the brand’s most aggressive concept car ever when wraps came off the GT4 Stinger at the North American International Auto Show (NAIAS).
Kia’s eye-catching design language moves in a bold new direction with the introduction of the GT4 Stinger. The concept pushes the boundaries of performance with a rear-drive 2+2 sports car that places man and machine in harmony on the road or track. It comes as no surprise that the GT4 Stinger is the wild style child of Kia’s California design team, home to its 2012 predecessor, the Track’ster concept. And like the Track’ster, the GT4 Stinger’s racy appeal is more than skin deep.

“Driving enjoyment was the number one priority in designing the GT4 Stinger,” said Tom Kearns, chief designer, Kia Design Center America (KDCA). “It’s a 2+2 sports car that can turn heads as a daily driver while also being right at home on the track. It’s about purity, simplicity and timelessness. The GT4 Stinger is a throwback to days when driving a car was a visceral experience that wasn’t muted by electronic gimmickry.”
Emboldened by the brand’s on-track success in the Pirelli World Challenge racing series with a pair of turbocharged, GTS-class Optimas, Kia’s U.S. design team approached the GT4 Stinger project with an eye toward weight reduction, functionality and pure driving enjoyment. The concept shuns the luxury trappings of a traditional Grand Touring car and embraces the elemental experience of truly engaging with the vehicle. “If anyone were to ask if Kia has the credibility to build a car like the GT4 Stinger,” noted Kearns. “I would simply point out that Kia races – and wins – against some of the world’s most legendary performance brands.”
Kia Racing and partner Kinetic Motorsports captured the Grand-Am Continental Tire Sports Car Challenge Drivers and Team Championships in 2012 with the Forte Koup and are currently preparing the turbocharged Optimas for their third season of duty in the Pirelli World Challenge in 2014 following a second-place finish in the Manufacturer’s Championship last year.
Kia GT4 Stinger Concept Power and Performance
Beneath the low wedge of the GT4 Stinger’s hood resides a tuned version of Kia’s proven 2.0-litre turbocharged gasoline direct injected (T-GDI) four-cylinder engine putting out an impressive 315 horsepower. “Our Optima racecars use the same engine and can produce more than 400 horsepower,” said Kearns. “So why not infuse our concept with the kind of power that will make people take notice?”
That power is put to the ground via a close-ratio six-speed manual transmission driving the rear wheels, which are wrapped in 275/35R-20 Pirelli P-Zero performance tires. Staggered 235/35R-20 Pirelli P-Zeros nestle beneath the front fenders, ensuring loads of corner-carving grip. Custom 20-inch aluminum centre-lock wheels feature carbon fibre inserts for strength and weight reduction. Tucked inside the massive wheels are Brembo Gran Turismo two-piece 15-inch cross-drilled rotors and four-piston calipers with plenty of stopping power.
Underpinning the GT4 Stinger’s sculpted “Ignition Yellow” body is a custom chassis with independent double wishbone suspension. With a shorter wheelbase (103.1 inches) and overall length (169.7 inches) than a Forte sedan, a width (74.4 inches) greater than a Cadenza, and a swooping roofline nearly nine inches lower (49.2 inches) than a Rio subcompact, the GT4 Stinger cuts a menacing figure. It tips the scales at a scant 2,874 pounds, and weight distribution is spread nearly perfectly at 52 per cent up front and 48 per cent at the rear. The GT4 Stinger also features a quick-ratio steering rack for direct feedback and uncompromised control.
