Hyundai’s Rear-drive Sport Coupe Receives More Powerful Powertrain Technologies, More Aggressive Design, Upscale Interior Refinement and Blue Link(r) Telematics
DETROIT, Jan. 9, 2012– Hyundai Motor America today introduced the significantly redesigned 2013 Genesis Coupe in a North American debut at the Detroit North American International Auto Show. In keeping with impressive performance upgrades, Genesis Coupe now sports more aggressive coupe styling, complemented by improved interior materials and design. Both 4-cylinder and V6 engines benefit from significant technology enhancements, with the 3.8-liter V6 engine receiving sophisticated direct-injection technology and the 2.0-liter turbocharged engine upgrading to a more precise twin-scroll turbocharger and larger intercooler. Automatic transmissions for these two models now have 8-speeds, with paddle-shift SHIFTRONIC(r) manual-shifting capability. Hyundai’s proprietary telematics platform, Blue Link(r), is now available, providing Genesis Coupe owners with a variety of infotainment services to meet their individual connectivity needs.

AGGRESSIVE DESIGN CUES MATCH ENHANCED DYNAMIC PERFORMANCE
The refreshed Genesis Coupe strikes a more menacing demeanor, with an aggressively redesigned front fascia, grille, headlights, LED daytime running lights, fog lights and hood with heat extractor cues. The side view reveals new, aggressive 18- and 19-inch alloy wheel designs with deeper dimensional sculpting. Finally, the rear taillights provide a visual spark via premium LED illumination and new contours. Of course, the traditional rear-drive sport coupe proportions remain, with a long wheelbase and short front and rear overhangs producing a classic wedge-like profile. Genesis Coupe’s bodyside character line is an innovative “Z”-shaped design that integrates seamlessly with a unique, drop-beltline rear window graphic.
Genesis Coupe’s arching roofline and tapering greenhouse highlight the exterior profile and emphasize the car’s broad shoulders and wide stance. To complete the aggressive sports car look, the depth between the fenders and the greenhouse has been maximized.
Enlarged openings in the front fascia allow for better engine breathing along with a more aggressive look. Dual asymmetrical exhaust tips integrated with the blackout rear diffuser treatment complete the performance message from the rear.
POWERTRAIN ENHANCEMENTS
Both Genesis Coupe engines receive significant technology upgrades, backing up its new design statement with impressive performance gains. The 3.8-liter Lambda DOHC V6 engine adds sophisticated direct-injection technology, adding 42 horsepower (a generous 14 percent increase) and 29 lb.-ft of torque (an eleven percent increase). Peak horsepower rises to 348 at 6,400 RPM, with peak torque increasing to 295 lb.-ft. at 5,300 RPM on premium fuel. In addition, lambda-engine anti-knock technology gives this V6 the versatility to run on regular fuel. This new direct-injected engine will easily propel the Genesis Coupe from zero to 60 mph in the lower five-second range on its way to an impressive 149 mph electronically-limited top speed. The Lambda V6 intake system also now employs an intake sound induction pipe into the cabin to ensure this engine’s aural character matches its visceral appeal.
To further broaden the power band, the 3.8-liter engine uses Dual Continuously Variable Valve Timing (Dual CVVT) and a Variable Intake System (VIS) that helps cylinders breathe most efficiently at both low and high RPM. The combination of high-pressure, precisely-metered direct injection with efficient cylinder breathing results in outstanding throttle response and off-the-line acceleration coupled with remarkable fuel efficiency. The V6 engine uses an alloy block and cylinder heads for lighter weight and thermal efficiency and features durable, quiet timing chains with no scheduled maintenance.
All these technologies serve to give Genesis Coupe 3.8 an impressive power-to-weight ratio of only 10.0:1; significantly lower than the more expensive Infiniti G37 and BMW 335i.

Not to be outdone by its bigger brother, the turbocharged, intercooled 2.0-liter DOHC inline four-cylinder substitutes a new twin-scroll design for its turbocharger in addition to a larger intercooler with enhanced thermal efficiency. The twin-scroll design is more efficient at recovering exhaust energy and produces cooler cylinder temperatures than the former single-scroll design. In addition, the twin-scroll is more precise, with improved combustion efficiency, reduced turbo lag, leaner air/fuel ratios and more evenly distributed pressure in the exhaust ports, resulting in simultaneous power, efficiency and emissions improvements. Also, a 53 percent larger intercooler further reduces intake temperatures, providing denser, cooler air from which to develop even more power.
This turbocharged engine also benefits from Dual CVVT on both intake and exhaust camshafts. The 2.0-liter turbo now generates 274 horsepower (a massive 30 percent increase) and 275 lb.-ft. of torque (an impressive 23 percent increase) on premium fuel. And, unlike many competitive turbo engines, this turbo’s anti-knock sensors automatically adjust ignition timing and engine mapping to run perfectly on regular fuel, yielding 260 horsepower at 6,000 RPM and 260 lb.-ft. of torque at 2,000 RPM. The turbo engine also features a cast-aluminum cylinder block and cylinder head. All these improvements give the Genesis Coupe 2.0T a power-to-weight ratio of 12.3, superior to the upcoming Scion FR-S sports coupe and the Honda Civic Si.

Both V6 and 4-cylinder engines also feature deeper, baritone-sounding dual cat-back exhausts to complement more efficient breathing on the intake side. To ensure that all this new power is evenly distributed to the pavement, Genesis Coupe also offers an available Torsen(r) limited-slip differential on R-Spec and Track models.
REAR-WHEEL-DRIVE ARCHITECTURE
2013 Genesis Coupe Body Shell Architecture
Genesis Coupe’s body shell makes generous use of ultra-high-tensile steel. The rear-wheel drive powertrain configuration provides a well-balanced 55:45 front-to-rear weight distribution for the 2.0T, and 56:44 for the 3.8 model.
SPORT-TUNED SUSPENSION
No well-tuned sport coupe chassis should give the perception of being overwhelmed by its powertrain, and Genesis Coupe is no exception to this rule. Spring, damper, and bushing ratings all have been precisely recalibrated to match these new powertrains with better road feel, more precise body motion control and improved ride comfort.
Genesis Coupe employs a MacPherson strut dual-link front suspension and a five-link rear suspension setup. The front suspension is mounted to the body via a solid subframe that is lighter and stronger than a comparable multi-piece component would be. To help reduce body roll and tune the Genesis Coupe’s at-the-limit handling for maximum predictability, 23-mm diameter front and 19-mm diameter rear stabilizer bars are fitted.

While all Genesis Coupe models offer a true rear-drive sport driving experience, the high-performance Genesis Coupe R-Spec and Track models raise the bar even higher with differentiated, track-tuned suspension calibrations. The R-Spec/Track suspension features both firmer front spring rates (seven percent) and rear spring rates (eleven percent), with matched damper rates. The Genesis Coupe R-Spec/Track models also deliver a significant increase in roll control over other versions of the Genesis Coupe via thicker stabilizer bars (24mm front/20mm rear). For 2013, all Genesis Coupes receive improved low-velocity-control dampers for refined ride comfort coupled with improved body control.
In addition, all R-Spec and Track models now receive front strut camber adjustment bolts that can be easily installed in the front strut assembly at their owner’s discretion. These camber adjustment bolts allow approximately -1.5 degrees of negative front camber adjustment for sharper, more responsive apex turn-in and significant understeer reduction in competitive events.
Of course, superb Genesis Coupe structural rigidity sets the fundamental foundation for dynamic precision, regardless of specific suspension calibration.
