Hyundai Genesis Coupe
Hyundai’s popular Genesis Coupe continues building its appeal in the fiercely-competitive sport coupe segment. For 2014, Genesis Coupe offers a number of key features and enhancements that add to its recognized market success as a rear-drive, high-output performance sport coupe for everyday enthusiasts.
The Genesis Coupe strikes a menacing demeanor, with an aggressively designed front fascia, grille, headlights, LED daytime running lights, fog lights and hood with heat extractor cues. The side view reveals aggressive 18- and 19-inch alloy wheel designs with deep dimensional sculpting. Finally, the rear taillights provide a visual spark via premium LED illumination and new contours. Traditional rear-drive sport coupe proportions are clearly evident, 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. Also, for 2014, heated outside mirrors and fog lights are standard on all Genesis Coupes.
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 is maximized. Large openings in the front fascia allow for optimal engine breathing coupled with an aggressive look. Dual asymmetrical exhaust tips integrated with the blackout rear diffuser treatment complete the performance message from the rear.
Both 4-cylinder and V6 engines offer sophisticated engine technology, with direct-injection on the 3.8 liter engine and a precise twin-scroll turbocharger with a large intercooler for the 2.0-liter turbocharged engine.
The 3.8-liter Lambda DOHC V6 engine produces 348 peak horsepower at 6,400 RPM, with peak torque of 295 lb.-ft. at 5,100 RPM on premium fuel. In addition, Lambda-engine anti-knock technology gives this V6 the versatility to run on regular fuel whenever required. This 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 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 Q60 and BMW 435i.
The turbocharged, intercooled 2.0-liter DOHC inline four-cylinder utilizes a twin-scroll design for its turbocharger with a large intercooler for enhanced thermal efficiency. The twin-scroll design is more efficient at recovering exhaust energy and produces cooler cylinder temperatures compared with a single-scroll design. In addition, a twin-scroll design 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 benefits over a single-scroll type. Also, a large 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 generates 274 horsepower and 275 lb.-ft. of torque 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 lightweight cast-aluminum cylinder block and cylinder head. All this gives the Genesis Coupe 2.0T a power-to-weight ratio of 12.3, superior to the Scion FR-S sports coupe and Honda Civic Si.
Both V6 and 4-cylinder engines also feature deep, baritone-sounding dual cat-back exhausts to complement efficient breathing on the intake side. For 2014, 2.0L Turbo models also feature an intake sound induction pipe, enhancing driver involvement during spirited driving. To ensure that all this power is evenly distributed to the pavement, Genesis Coupe also offers an available Torsen® limited-slip differential on R-Spec and Ultimate models.
The automatic transmissions for both engines have 8-speeds, with an enhanced paddle-shifter design for the SHIFTRONIC® manual-shifting capability. In addition, the 8-speed automatic now precisely rev-matches engine RPM to the exact selected-gear speed, for smooth downshifts into corners and superb dynamic balance.
Both engines are mated to standard six-speed manual transmissions that feature new carbon synchronizer rings for smoother shift action and enhanced synchronizer durability. Each transmission has been specifically tuned to match its engine’s unique power and torque curve characteristics.
In addition to the steering wheel-mounted paddle shifters, each automatic offers shift capability via the shift lever according to individual driver preference. A clear LCD readout on the instrument panel shows the selected gear at all times for the driver.
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.
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 calibrated to match these powertrains with superb road feel, precise body motion control and good 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, 23mm diameter front and 19mm diameter rear stabilizer bars are fitted.
While all Genesis Coupe models offer a true rear-drive sport coupe driving experience, the high-performance Genesis Coupe R-Spec and Ultimate models raise the bar even higher with a differentiated, track-tuned suspension. The R-Spec/Ultimate suspension features both firmer front spring rates (seven percent) and rear spring rates (11 percent), with matched damper rates. The Genesis Coupe R-Spec/Ultimate models also deliver a significant increase in roll control over other versions of the Genesis Coupe via thicker stabilizer bars (24mm front/20mm rear). Genesis Coupes also use low-velocity-control dampers for refined ride comfort coupled with excellent body control.
In addition, all R-Spec and Ultimate models 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 reduction of understeer in competitive events.
Of course, superb Genesis Coupe structural rigidity sets the fundamental foundation for dynamic precision, regardless of specific suspension calibration.
Hydraulic, RPM-sensing rack-and-pinion steering has been calibrated with a quick, 13.8:1 ratio, delivering both linear feel and agile response to driver inputs. This steering ratio yields intuitive steering response and precision. To further optimize driver ergonomics, tilt and telescopic adjustment is standard.
Brembo® four-piston calipers clamp down on fade-resistant 13.4-inch ventilated front brake rotors and 13-inch ventilated rear rotors on both R-Spec and Ultimate models. All other models get substantial 12.6-inch front ventilated rotors and 12.4-inch rotors in the rear with floating single-piston calipers.
The 2014 Genesis Coupe interior offers distinctive, upscale features and design cues. The leather steering wheel uses a more premium grade of leather. The instrument panel crash pad features a stitched-seam appearance for a distinctly upscale look, and the parking brake lever is leather-wrapped on leather-equipped models. The instrument cluster features an electroluminescent gauge cluster for premium ambience and superior readability. A driver-side rear seat walk-in assist function provides convenient rear seat access from the driver’s side. Convenient seatbelt assist guides make it easy for front passengers to buckle up. Cruise control and floor mats are now standard on all Genesis Coupes, and the Proximity-entry key has been redesigned. A center stack multi-gauge cluster with instantaneous mpg, torque level (3.8 models) or turbocharger boost pressure (2.0T models), and oil temperature is standard on all trims. A center fascia tray with cover provides extra storage, and interior surfaces have a soft touch with low sheen for an up-market feel. Sport front seats with deep side bolsters offer superb lateral support for enthusiastic driving in all trim configurations. For 2014, R-Spec seat bolsters are even deeper for extra support during spirited driving.
